IDC Released the Top Ten Forecasts of China's PC Market in 2021: the Beginning of a New Round of Processor War and the Large Screen of Notebook Screen

In the process of using notebook, whether the screen looks "comfortable" is very important, and there are many factors affecting the screen display effect. In this paper, we will comb them one by one.Screen sizeAt present, the common sizes of notebook screens include 11.6 inches, 13.3 inches, 14 inches, 15.6 inches, 16 inches and 17.3 inches. If you often go out with a notebook, please give priority to the notebook with a size of 14 inches or less; If you usually put your notebook in a fixed place such as home, office or dormitory, products with a size of 15.6 inches or larger can make you see better.display scaleThe display ratio of notebook screen is mainly 16:9 and 3:2, both of which are 14 inch notebooks. The screen with 16:9 display ratio can make the fuselage thinner and more suitable for watching video; The screen with 3:2 display ratio can shorten the length of the fuselage, reduce the width of the upper and lower borders of the screen and improve the proportion of the screen. This display ratio is also more suitable for office, and one screen can display more content.resolving powerThe higher the resolution of the notebook screen, the finer the picture will be displayed, but it will also bring problems such as too small text and icons. You need to use the "zoom" function of windows 10 display settings to zoom in to 125% 150% to see clearly. For the vast majority of ordinary users, the resolution of FHD level is sufficient, and the resolution of more than 2K is more suitable for professional design and graphics workers.Refresh rateThe standard refresh rate of notebook screen is 60Hz, and a few game books will be equipped with screens with refresh rates of 120Hz, 144hz or even 240Hz. These ultra-high refresh rate screens are often called "E-sports screens" by game players, which can effectively reduce the problems such as blurring and tearing of dynamic pictures, and make the game experience more smooth and smooth. If you like playing large 3D games, it is necessary to choose a game book with 144hz refresh rate screen and gtx1660ti or higher independent graphics card.Screen materialNotebook screen can be divided into LCD and OLED according to material. Among them, the LCD screen includes TN panel and IPS panel. The former has the lowest cost and has the problem of low visual angle (mainly in the vertical direction). When the angle is large, the screen will be color biased and white. The advantage of IPS panel is that the viewing angle is higher, ranging from 170 degrees to 180 degrees. At present, most of the screens of notebooks with a price of more than 4000 yuan are equipped with IPS panel.TN screenIPS screenOLED material screen has the advantages of rich colors and higher contrast. It hardly consumes power when displaying pure black pictures. The combination of black desktop and dark background is conducive to prolonging the battery life of notebook. However, the cost of OLED screen is very high. In the notebook field, only a few products with more than 10000 yuan have hunting clothes, which belongs to the patent of top equipped notebook.GamutColor gamut affects the restoration of color on the screen. The higher the color gamut means that the screen color display is more accurate and more comfortable. At present, the color gamut of notebook screen is generally dominated by 45% NTSC, 72% NTSC and 100% sRGB. Among them, 45% NTSC has the highest popularity and the worst color performance. Both 72% NTSC and 100% sRGB belong to "high color gamut". They have the same theoretical effect, but 100% sRGB is more suitable for people engaged in professional image design.High color gamut screen is just needed by users engaged in design workFog screenEarly notebook screens had "fog screen" and "mirror screen", both of which were directly "exposed", but the "mirror screen" added a layer of coating on the surface of the screen panel, forming a mirror like effect, which looked very high-grade. However, this mirror effect has serious reflection problems. Both sunlight and light will affect the normal viewing of the screen. Therefore, almost all new notebook products listed in recent years are "fog screen".Glass coverIn addition to notebooks that support touch operation, there are many lightweight notebooks that are covered with a layer of glass cover on the surface of the screen panel, which can protect the screen and make the machine look more high-grade. However, the protective glass will increase the weight of the whole machine and bring some reflection problems. It belongs to the advanced version of the "mirror screen" in the past.Anti glare coatingEven the "fog screen" also has a certain degree of reflection. Therefore, many notebooks now add an anti glare coating on the surface of the screen panel (or protective glass), which can further reduce the refraction of light and maximize the sensory experience of using notebooks outdoors (under lights).Replace screenMost laptop screens are removable. If you are not satisfied with the screen color or resolution, you can buy the screen panel on Taobao, and then replace and upgrade it yourself.Nowadays, most of the new notebook screen panels use EDP interface, but the interface has the difference between single channel and dual channel. The latter has 30pins and can support higher resolution signals. If you need to upgrade the screen in the future, be sure to confirm in advance whether the notebook is compatible with the (New) screen panel.

Screen the world! Talking about the use and maintenance skills of the screenWith the continuous diving of notebook prices and the improvement of living standards, more and more people use notebooks, and some people have even gradually replaced desktops with notebooks. However, all parts of the notebook have a service life, and I'm afraid the most delicate one is the LCD screen. You should know that the normal use time of a LCD screen is about 5 years. With the passage of time, the laptop screen will become more and more yellow. This is the phenomenon of aging of light tubes in the screen.It is normal, so how to reverse the aging time as much as possible? Let's extend the service life of your screen through a few simple tips on the use and maintenance of notebook screen. 1 Don't worry about the working principle of the LCD screen. Before learning how to correctly use and maintain the LCD screen, let's briefly understand how the LCD screen works, which will be of great benefit to our correct use and maintenance of the LCD screen in the future. The traditional CRT display mainly relies on the electron beam emitted by the electron gun in the picture tube to shoot the phosphor inside the display screen to emit light. Under the intentional interference of the artificial magnetic field inside the display, the electron beam will deflect at a certain angle, scan the phosphor of the target cell and display different colors. TFT-LCD adopts the backlight principle, uses the lamp tube as the backlight source, and achieves an ideal display effect through the control of light by auxiliary optical module and liquid crystal layer.Liquid crystal is an organic compound with regular arrangement. It is a substance between solid and liquid. At present, the molecular arrangement is generally used. Nematic thin column liquid crystal is most suitable for manufacturing liquid crystal displays. Liquid crystal itself does not emit light.It mainly displays images by changing the arrangement of liquid crystal molecules due to the electric field generated by the change of voltage. The liquid crystal panel is mainly composed of two sodium free glass sandwiched with an interlayer composed of polarizing plate, liquid crystal layer and color light filter. Polarizer and color filter determine how much light can pass through and what color of light can be generated. The liquid crystal is poured between two well-made planes to form a liquid crystal layer. There are many grooves on the two planes.The grooves on a single plane are parallel, but the grooves on the two parallel planes are perpendicular to each other. Simply put, if the grooves on the back plane are arranged vertically, the front plane is arranged horizontally. The arrangement of liquid crystal molecules between two planes will form a gradually distorted state of 90 degrees in the z-axis. The backlight light source is the light emitted by the lamp tube, which generates uniform backlight light through the backlight plate and reflective film on the back of the LCD. These light will be distorted by the liquid crystal in the z-axis through the rear layer, so as to pass through the plane of the front layer. If a voltage is applied to the liquid crystal layer, an electric field will be generated, and the liquid crystal molecules will rearrange, and the light cannot be twisted, so it cannot pass through the front plane, so as to block the light. 2 Correct habit of using LCD screen after understanding the working principle of LCD screen, let's learn about the correct habit of using LCD screen. 1. Do not use the screen saver.The liquid crystal screen controls the transmission of light by relying on the molecular arrangement of the liquid crystal. Each change in the image means a change in the molecular arrangement, just like a switching action of the power switch. As we all know, the power switches are frequent. Even if there is no damage to the switches, it is inevitable that the switches will be aged, resulting in slow response or even failure of the switches, which is fatal to the LCD screen! Therefore, if you don't want your notebook's screen to age prematurely, try not to open and close the LCD screen frequently when not in use. Speaking of which, what do you think? yes! Is a screen saver! For this LCD screen, the screen saver, which is very popular on this computer, is a very harmful poison!! The reason why the screen saver came into being was that the green fluorescent screen of the early IBM PC displayed the same content for a long time, which was easy to leave the displayed content after the screen was closed, which was not conducive to the confidentiality of data and even affected the service life of the display. Therefore, there was the screen saver.However, the manufacturing technology of the display has long been improved, and there will be no problem for the display to display the same content all night. However, due to the decorative function and confidentiality function of the screensaver, it still remains. As for "screen protection", even for CRT displays, it has no effect for a long time. As for LCD, not to mention that. When the screen is turned on, the lamp will light up.When you see black, only the light is reflected upward, but the screen is still working. Can it not affect his life? Therefore, the best way to protect the display (whether CRT or LCD) is to turn it off when not in use! Many notebooks now provide shortcut keys to turn off the LCD screen, such as FN F3 of IBM notebooks. You can turn off the screen or close the screen directly when you don't use the notebook screen temporarily, which can effectively prolong the screen life. 2. At ordinary times, try to reduce the possibility of direct exposure of the screen under strong light. When using it during the day, try to close the curtains to prevent the screen from being exposed to strong light, resulting in too high temperature and accelerating aging. 3. The simplest way to delay the aging of the screen is to reduce the brightness of the screen. Generally, 3-4 grids are enough during the day, and only 1-2 grids are needed at night.For brightness and lifetime, I believe we still prefer the latter? Sometimes the system will restore the default brightness after restart. At this time, the screen is generally particularly bright. For the sake of the screen life, you must remember to adjust it back. 4. The LCD screen is one of the most vulnerable components of the notebook. Remember not to "point" on the screen with sharp objects such as pens and keys. As for the consequences of doing so, I have not tried and am not willing to experiment.I just remind you that in case of bad spots or color spots, you will cry! It was too late for you to regret!! 3 As the saying goes, "if you want to do a good job, you must first sharpen the device". The most important tool for daily maintenance of LCD screen is the tool. Here, the tool I strongly recommend to you is 3M Scotch Brite lens cleaning cloth - a special rag commonly known as "magic cloth" (available in major supermarkets, selling price: 17.90 (small pieces), 27.90 (block)). The picture is as follows:.3M Sego polishing is a cleaning cloth specially used to wipe the smooth surface launched by 3M company. Although it looks very rough, in fact, due to the use of patented fiber materials and specially designed fluff structure, its cleaning ability is abnormal. It can not only effectively clean the dust and dirt on the screen, but also ensure the cleaning process There will be no fluff falling off and the screen will not be scratched! The performance is really excellent!In addition to wiping the LCD screen, it can also wipe the CRT screen, TV screen, all kinds of lenses, and even furniture. Therefore, 3M "Sego wipe light" is also recommended as a special wiping cloth for lens lens, as shown in the figure:Are you doubting that a rag can do a good job in the maintenance of the LCD screen? Hehe, of course, 3M Sego is enough for general maintenance. If your notebook is in a poor environment and you are not well protected, we have to hire two strong generals from two outside "Claire mopaco 'magic pake' scratch resistant repair towel and 3M LCD screen cleaner. Magic pake is made of Spunlaced cloth and special cleaning solution. It has the effects of dust removal, decontamination, sterilization, disinfection, anti-static, increasing brightness and so on. It can be widely used in the cleaning and maintenance of digital products. It is small and easy to carry. It has obvious effect in dust protection. It is said that its function is also good." It has the advantages of rapid sterilization, disinfection, decontamination and freshness preservation, repairing scratched seams of the shell, forming a special protective film after use, anti-static, anti moisture, anti magnetism, etc. it can resist scratches, preserve freshness and preserve value, protect environment and health, etc. but I have no chance to actually experience these functions in use. As shown in the figure:3M cleaner is also a special cleaning tool for 3M. It can clean the computer screen, the surface of the filter and the TV screen. It is convenient and easy to use, with the unique brush type antistatic wipes and spray cleaner. It can not only dust and finger marks, but also prevent static electricity and reduce the accumulation of dust. It can be applied to the computer screen as well as 3M magic cloth. LCD screen, CRT computer display, TV screen, camera, projector lens, TV, computer shell, etc. as shown in the figure:With the escort of these two generals, I believe your LCD screen can be guaranteed! Fourth, with appropriate tools for maintenance procedures, let's clean it step by step to ensure the integrity of the LCD screen! First, we unplug the power of the notebook and remove the battery to make the notebook completely powered off (I'll forget the BIOS battery. You don't want to wash it with the motherboard, do you?) In order to avoid electric leakage or short circuit due to water inflow during cleaning, we wet 3M magic cloth with water and then screw it to 90% dry to clean the LCD screen. The cleaning method is similar to that of cleaning the TV screen at home. Generally, it starts from the center of the screen and wipes it clockwise. In fact, if the screen is not very dirty, There is no need to wet 3M magic cloth. Just wipe it with dry magic cloth. In case of stubborn stains, just use a little "breath" Wipe the LCD screen with magic cloth immediately. Generally, it can be wiped clean. After wiping the LCD screen with wet 3M magic cloth, put the laptop LCD screen and magic cloth together in the shade and let it dry naturally. The LCD screen wiped with wet magic cloth may have water stains. At this time, wipe it with dry magic cloth. The cleaned LCD screen has been cleaned It's as clean as new. But we can't be satisfied, because we still have to lay a foundation for future use. Next, we open a package of magic pake's oily wipes and use it to wipe the screen clockwise from the center to the periphery according to the above steps. According to magic pake's instructions, if we can rub to generate heat during the wiping process, we can get better results Good effect. Therefore, we can wipe it for a period of time until the friction generates heat. Then place it for 5 minutes, and then wipe the screen surface with 3M magic cloth. If you don't feel at ease, you can continue to use 3M screen cleaner to add a layer of protection to the screen of your beloved notebook. Well, the cleaning of the notebook screen has been completed by now Yes. Looking at the new screen, do you have a book that has been "reborn"

On January 6, IDC released the top ten forecasts for China's PC market in 2021, including the popularization of high color gamut of consumer notebooks, the beginning of a new round of processor war, the large screen of notebook screens, etc.IDC said that 2021 will be the first year of a new round of war in the PC processor market. On the one hand, Intel will switch 11 generation CPUs on a large scale and more perfectly support AI, Wi Fi 6, Xe display and other functions.Amd continues to maintain its leading edge in the process; The M1 processor launched by Apple also allows the industry to reconsider the feasibility of arm architecture PC in the future; In addition, Qualcomm will promote the latest Xiaolong 888 processor in 2021, and its performance will be further improved.In addition, domestic PC processors will also be greatly popularized in the government and other markets. All this indicates that the prelude to a new round of processor war has begun.In 2020, China's PC market affected by the epidemic was like a roller coaster. In the first quarter of 2020, China's PC market decreased by 28.1% year-on-year, but the year-on-year growth in the following three quarters was about 10% respectively.Therefore, IDC predicts that China's PC market will grow by 1.7% in 2020. It was a milestone year for the first time after eight consecutive years of negative growth.The following are the top ten forecasts of China's PC market in 2021:Forecast 1:With the popularization of high color gamut of consumer notebooks, with the improvement of PC heavy application attributes, consumers' requirements for screen quality have significantly improved. It is estimated that more than 65% of consumer notebooks will be equipped with high color gamut screens in 2021 (NTSC 72% or sRGB 100% or more).Forecast 2:Special notebooks for primary and secondary school students. The epidemic has accelerated the use of computers for primary and secondary school students such as online learning. In 2021, the shipment of computers for auxiliary learning for primary and secondary school students will reach about 8.8 million, which is about six times the demand of K12 in 2019 and nearly 1 / 3 of the scale of consumer PC market. With the stable growth of the market in the future, manufacturers will also launch exclusive primary and secondary school computers.Forecast 3:A new round of processor war begins. 2021 will be the first year of a new round of war in the PC processor market. On the one hand, Intel will switch 11 generation CPUs on a large scale and more perfectly support AI, WiFi 6, Xe display and other functions. Amd continues to maintain its leading edge in the process; The M1 processor launched by Apple also allows the industry to reconsider the feasibility of arm architecture PC in the future; In addition, Qualcomm will promote the latest Xiaolong 888 processor in 2021, and its performance will be further improved. In addition, domestic PC processors will also be greatly popularized in the government and other markets. All this indicates that the prelude to a new round of processor war has begun.Forecast 4:The notebook screen is larger. With the notebook becoming lighter and thinner, customers are looking for a larger screen to improve the customer experience. Therefore, there will be a downward trend in the notebook market of 13 inch and below in 2021, and more customers will turn to the notebook market of more than 14 inch.Forecast 5:With the grading and integration of game notebooks, the proportion of RTX graphics cards in game books will reach about 40% in the fourth quarter of 2020, which leads to the gradual division of the game book market into two sub markets: competitive high-end game books represented by RTX graphics cards and ordinary game books represented by GTX graphics cards. It is expected that this two-level differentiation will continue in the first half of 2021. With the price reduction of RTX in the second half of 2021, the game notebook will usher in a new wave of integrated development.Forecast 6:As more and more manufacturers launch cloud PC solutions, whether the front-end computing power will decline has become an important topic. At present, in the next three years, PC scenarios will increasingly focus on heavy productivity application scenarios. Cloud computing will effectively share the problem of insufficient front-end computing power, but the improvement of front-end computing power is still the core direction in the next three years.Forecast 7:Touch screen, with the growth of digital natives, more young consumers are used to multiple modes of interaction. Voice, video, touch, etc. In 2023, more than 10% of laptops will support touch, 10% will support voice education and 7% will support visual interaction.Forecast 8:The competition pattern of subversion and defense. With the rebound of the PC industry caused by the impact of the epidemic and localization, more manufacturers will consider increasing PC sales business in 2021. They subvert through killer applications or quickly enter the market through their own customer relations. On the other hand, traditional global PC manufacturers still have strong R & D, product and scale advantages. In the next three years, 50% of new entrants will withdraw from the PC market due to acclimatization, and some intermediate PC manufacturers will experience periodic business decline.Forecast 9:Digital native enterprises drive the new demand for PC. IDC divides commercial enterprises into four categories: Digital driven, digital native, public following and sticking to stereotypes. In recent years, more new enterprise business models have been built on the basis of digitization, the number of digital original biochemical enterprises has increased significantly, and PC has helped enterprises transform in many aspects such as future culture, future labor force and future space. It is estimated that the demand growth rate of digital native enterprises for PCs will exceed 20% in 2021.Forecast 10:Online and offline integrated development. In 2020, 41% of PCs will be sold online, and the proportion of e-commerce is increasing, which has changed the marketing mode of China's overall channel system. In 2021, more than 35% of offline retail stores will open stores in e-commerce to enrich their sales channels. Online and offline coupling marketing has become a new idea in the future.

There are many parameters that affect the display effect of notebook screen, such as resolution, refresh rate and color gamut. Generally speaking, the notebook with better screen quality will be more expensive. If you are not satisfied with the display effect of the new laptop screen, you might as well try to manually adjust and optimize it through the system and driver settings.Many notebook screens feel uncomfortable, either yellow or blue, or the white display is not pure enough, and the details in the dark background picture can not be seen clearly.In this case, we can alleviate it by calibrating the display (note that it is only mitigation, which is strongly related to the quality of the panel). Enter "color management" in the search box of windows 10, switch to the "advanced" tab in the color management window, and click "calibrate display".In the display color calibration window, click "next" continuously according to the prompt to enter the interface for adjusting gamma value. Gamma defines the mathematical relationship between the red, green and blue values of the display and the final amount of light emitted by the screen, which can alleviate some display problems mentioned above to a great extent.The problem is that when adjusting gamma, you need to use the button on the front of the display panel to fine tune it through the OSD setting interface. However, there is no setting button on the notebook screen. At this time, how to accurately adjust parameters such as brightness and contrast?For notebooks equipped with intel core processors, right-click on the desktop to find and enter Intel graphics card settings; For notebooks equipped with AMD processor, you can use the same method to find and enter the "amd graphics card control panel", where you can set more advanced screen parameters.Taking Intel platform notebook as an example, enter the control panel of Intel super core graphics card, and you can adjust parameters such as brightness and contrast in "display color setting".Arrange the windows 10 system display color calibration window and the Intel graphics card control panel side by side. According to the instructions of the former interface, continuously fine tune the brightness and contrast on the latter interface until the best display state prompted by the interface is found.Next, the display color calibration of windows 10 system will enter the "color balance" window, and fine tune the red, green and blue sliders according to the interface prompts, which can make up for the color deviation of the notebook screen panel to a certain extent.So far, the manual color correction of the notebook is over. We can switch between the previous state and the current state with one button. If you are more satisfied with the display effect after correction, click OK. If you are not satisfied, you can repeat the above process until you find the most comfortable point for your eyes.

I believe you should know about the CPU, hard disk and other parameters of the notebook. When we focus on the machine configuration, we often ignore the parameters of the screen. In fact, for the screen, we can at most look at the brightness or whether there are bad points, and few people ask about the specific parameters, and few people understand.I believe you should know about the CPU, hard disk and other parameters of the notebook. When we focus on the machine configuration, we often ignore the parameters of the screen. In fact, for the screen, we can at most look at the brightness or whether there are bad points, and few people ask about the specific parameters, and few people understand. For the reasons of volume and weight, the LCD screen used in the notebook is different from the ordinary 14 or 15 inches. In addition to special needs, few laptops can be equipped with LCD more than 15 inches. In order to enable users to see more content in a limited space, LCD manufacturers have adopted the method of improving the display resolution. The display area is expanded by increasing the pixels available for display in the LCD of the same size. This is why we can see XGA, SXGA and uxga parameters in notebooks with the same screen size. So what do the English letters XGA and SXGA mean? Let's explain:VGA: the full name is video graphics array. This kind of screen has generally disappeared in this book. It is a screen used in very old books, and supports a maximum resolution of 640 480, but some small portable devices still use this screen. SVGA: the full name is super video graphics array, which is a substitute for VGA screen and supports up to 800 600 resolution, the screen size is 12.1 inches. Due to the low pixels, there are few books using this screen at present. XGA: the full name is extended graphics array, which is an LCD screen commonly used in notebooks. Nearly 80% of notebooks on the market will use this product. It supports a maximum of 1024 768 resolution, screen size from 10.4 inches, 12.1 inches, 13.3 inches to 14.1 inches, 15.1 inches. SXGA : the full name is super extended graphics array. As an extension of SXGA, SXGA is a screen specially designed for notebooks. Its display resolution is 1400 1050 Because the horizontal and vertical dot distances of notebook LCD screen are different from ordinary desktop LCD, its display accuracy is much higher than that of ordinary 17 inch desktop LCD. Uvga: full name: Ultra video graphics array. This screen is applied to the notebook with a 15 inch screen and supports a maximum of 1600 1200 resolution. Due to the high requirements for manufacturing process, the price is also relatively expensive. At present, only a few high-end mobile workstations are equipped with this type of screen. Most of the above are conventional 4:3 screens, and now the products with wide screen design are more and more loved by users. The so-called widescreen notebook is a book that widens the screen according to the ratio of 16:10. Compared with most 4:3 screens, this product is more suitable for the aspect ratio of DVD films, so there will be no problem of image deformation or inability to display images on both sides when watching DVD. It can be roughly divided into the following categories:WXGA (wide extended graphics array): as a wide screen version of ordinary XGA screen, WXGA uses a 16:10 horizontal width ratio to expand the size of the screen. Its maximum display resolution is 1280 800 Because its horizontal pixels are only 800, many 12.1-inch books use this type of screen in addition to the general 15 inch books. WXGA (wide extended graphics array): This is an extension of WXGA with a maximum display resolution of 1280 854 Because its transverse width ratio is 15:10 instead of 16:10 of the standard widescreen. Therefore, only a few books with a screen size of 15.2 inches use this product. WSXGA (wide super Extended Graphics Array): its display resolution is 1680 1050. In addition to most widescreen notebooks over 15 inches, the popular large-size LCD-TV also adopts this type of products. WUXGA (wide ultra video graphics array): like the uxga in the 4:3 specification, WUXGA screen is very rare, and its display resolution can reach 1920 1200 Because the price is too high, few notebook manufacturers use this product. At present, only workstation level Dell Inspiron 8600 and apple powerbook G4 are known to use products with this resolution.

1. Screen saver, bag selection, great knowledgeWe must not ignore the protective effect of notebook bag on notebook screen. But it is not so easy to buy a notebook bag, especially for the "mobile people" who often go out with a notebook, it is more necessary to buy a well-made, thick and reliable notebook bag for your notebook. In the market, Benben's coat can be said to be mixed, good and bad, and the price range ranges from more than ten yuan to thousands. Every penny is worth every penny. Buying notebook bags of famous brands can effectively prevent "accidents". For example, the highly praised IBM red dot bag and the professional caselogic bag are good choices. In addition, some notebook bags adopt waterproof fabrics, which can effectively prevent the erosion damage of rainwater to notebook LCD and other internal components. It is more suitable for people who often work outdoors. Of course, don't think it's all right to have a good bag. It's best to try to avoid carrying a notebook out in rainy days, touching or falling a notebook. Pay special attention to the placement of items in the bag. Batteries, power adapters, external lights, floppy drives and other accessories should be placed in special bags in the bag, To avoid squeezing the top cover of the notebook and causing damage to the LCD screen. Finally, hard objects such as keys and locks are the culprit of the book's flowers. We must avoid putting them in the bag with the book.2. Do not press the top cover of the housingSome people like to take a square book as a table and put things on it. This is not a good habit. Applying pressure on the top cover of the laptop shell will cause damage to the external LCD. Don't believe it? Try squeezing the top cover of the notebook with your fingers, and water ripples will appear in the corresponding parts of most notebook screens. This is because the liquid crystal display has several layers, which are: vertical linear polarizer, glass sheet, transparent X electrode, calibration layer, liquid crystal flow, calibration layer, transparent Y electrode, glass sheet and horizontal linear light encoder. These materials are very fragile and easily damaged, so once the external force is too large, it will cause irreparable damage to the LCD. Generally speaking, except for a few specially designed notebooks (such as the radian design of Sony's R505 series top cover, and some IBM ThinkPad notebooks adopt titanium alloy shell), the design and manufacturing strength of the top cover of most notebooks is not enough to ensure that its deformation will not affect the LCD in this case. Therefore, we should not use the book as a table for setting things in the future.3. Don't ignore the opening and closing of the upper coverThe opening and closing of the upper cover can be said to be a "habitual action" that everyone has to do every day. However, are you sure that you must be right if you do it many times a day? In fact, due to the pursuit of lightness, some notebooks have to sacrifice the strength of the top cover in design. Moreover, the connecting shaft between the top cover and the fuselage of most notebooks is made of plastic, which is easy to cause the connecting shaft to break or even separate, and then hurt the display and power supply cable of the LCD screen in the connecting shaft. Therefore, it is necessary to open and close in the middle of the front edge of the top cover, and pay attention to the uniform force and as gentle as possible.4. Pay special attention to "deadly" drinksDrinks are fatal to the keyboard and host! It also does great harm to the LCD screen, especially some juicy and greasy food, which is difficult to avoid splashing on the LCD screen and causing stains that are difficult to clean. Therefore, whether from the perspective of hygiene or safe use, please try to avoid the habit of using the computer while eating.5. Pay attention to humidity and temperature differenceAlthough it is called LCD, LCD is naturally afraid of water. Therefore, pay attention not to store the machine in a wet place. Serious moisture will damage the components inside the LCD; In addition, don't think that with air conditioning and heating control temperature, everything will be fine. The temperature difference when entering and leaving a room with heating or air conditioning will lead to "condensation". If the LCD is powered on at this time, it will lead to corrosion of the LCD electrode and permanent damage. Therefore, if you find that there is only fog on the screen surface before starting up, you must wipe it off gently with a soft cloth before starting up. If the water has entered the LCD, put the LCD in a warmer place, such as under a desk lamp, and evaporate the water gradually before starting the LCD. More troublesome is the plum rain season in the south every year. At that time, even if you don't use a notebook, you'd better turn on the power regularly and let the machine run for a period of time, so as to heat components and disperse moisture, and you'd better put a small bag of moisture-proof agent in the notebook bag.6. Pay attention to wiping and cleaningDust and stains are inevitable. Of course, wiping and cleaning are also exquisite. The LCD screen is a delicate part. If it is not too dirty, you can use a soft wool brush to gently brush it. It is recommended to use an ordinary cosmetic brush. The hair of this brush is very soft and will not scratch the screen. It is also easier to buy. If you don't have it for the time being, you can try blowing it off with an ear ball. If it is too dirty, you can use a clean cotton cloth with water for careful cleaning. Note that you must not use any chemicals to clean the LCD screen! Sometimes you may encounter some very stubborn stains. At this time, you need to hire a professional - kk-lc3, a special cleaner for LCD produced by Sony! Of course, the price of this LCD stain killer is very high. A small bottle costs about RMB 150, and the effect is naturally indisputable. In fact, you can also consider using soft and smooth cotton or suede glasses cloth dipped in a small amount of water to wipe. Although the effect is not as perfect as professionals, it is cheaper. Friendly reminder: wiping must be carried out in the off state, and the amount of detergent or clean water should not be too much.7. Leave a piece of useful cotton paperI don't know if you have noticed. The newly purchased machine will be separated by a piece of cotton paper between the keyboard and the LCD screen. Otherwise, when the laptop is closed, the keyboard and LCD may rub, resulting in a flower screen. Some advanced notebooks have their own methods to solve this problem. For example, the UM series machine of sharp adopts a novel keyboard lifting technology. When the laptop is closed, the keyboard will automatically drop by 3mm. Some books provide LCD protective covers. But for other laptop users, the most effective way is to keep the cotton paper of the new machine on the keyboard.8. Dismantling is not our job"To avoid electric shock, do not open the back cover by yourself. For service, please contact professional or authorized personnel." is this sentence familiar? These are some classic sentences in the manuals of many electronic products, including notebooks. In fact, like other electronic products, high voltage will be generated inside the LCD, so it is very dangerous to disassemble it without permission. Therefore, never attempt to disassemble the LCD. This is no longer a problem of exploration and do it yourself. If you have any problems with your beloved notebook's LCD display, you'd better hand it over to a professional to disassemble it!9. Different flicker modes of LCD screen have different meanings. Due to the influence of analog signal output interface, for example, the clock and phase of pixels are not synchronized with analog signal output, which will lead to flicker. This phenomenon is usually called pixel jitter. It is an occasional flicker phenomenon, which is inevitable in the process of analog / digital conversion. In order to solve this kind of problem, there are two methods. It can be "automatically adjusted". There is a "automatic setting" function on the LCD screen, which is used to adjust the LCD screen to the best state after analyzing the input signal. It can also be "manually adjusted", which can be adjusted by two functions: phase and clock. However, if it flickers regularly or often for unknown reasons, there may be a real problem with the screen. First check whether there is a poor contact. If not, the LCD screen itself may have failed.

First of all, we unplug the power supply of the notebook and remove the battery to make the notebook in the state of complete power failure (I'll forget the BIOS battery, don't you want to wash it with the motherboard?) so as to avoid leakage during cleaning or short circuit due to water inflow;Then, we wet the 3M magic cloth with water, then screw it to 90% dry, and use it to clean the LCD screen. The cleaning method is similar to that of cleaning the TV screen at home. Generally, we start from the center of the screen and wipe it clockwise. In fact, if the screen is not very dirty, there is no need to wet the 3M magic cloth. Just wipe it with a dry magic cloth. In case of stubborn stains, you can wipe it clean as long as you use a little "breath" and then wipe it immediately with a magic cloth. After wiping the LCD screen with a wet 3M magic cloth, put the LCD screen of the notebook together with the magic cloth in the shade and let it dry naturally.There may be water stains on the LCD screen after wiping with a wet magic cloth. At this time, wipe it with a dry magic cloth.After such cleaning, the LCD screen is as clean as new. But we can't meet it, because we have to lay a certain foundation for future use.Next, we open a pack of magic pake's oily wipes and use it to wipe the screen clockwise from the center to the periphery according to the above steps. According to the instructions of magic pake, if you can rub to generate heat during the wiping process, you can get a better effect. Therefore, we can wipe for a period of time until friction generates heat. Then place it for 5 minutes, and then wipe the screen surface with 3M magic cloth.If you don't feel at ease, you can continue to use 3M screen cleaner to add a layer of protection to the screen of your beloved notebook.Well, so far, the cleaning of this screen has been completed. Looking at the screen as clean as new, do you feel that the book has been "reborn"? However, cleaning is only temporary. You should pay attention to it in your usual use!All my tips have been taught to you. Next, it's up to you!

It is a very enviable and happy thing to have a expensive laptop."Why is the battery life of my laptop gradually shortening?" "why is the laptop screen not too bright after less than a year?" this is something we often hear from our friends. Is there something wrong with the machine itself or do we neglect some nuances when using it on weekdays?Notebook computer is a high-tech and high-precision product. In order to use it well, prolong its service life and maintain good working condition, reasonable use methods and correct maintenance are very necessary. It is hoped that the following knowledge will enable users who already have laptops to know more clearly how to use laptops correctly and reasonably, so as to prolong the service life of their "office entertainment" equipment and improve the data security in laptops.A. Do not press, squeeze, fall or smash.Applying pressure to the LCD display surface will cause damage to the LCD screen and CFL unit. Therefore, be careful not to apply pressure to the LCD display surface.In the protection of laptop screen, the most taboo is to press, top, scratch and incorrect screen opening mode. The LCD screen of laptop is composed of many layers of reflector, filter plate and protective film. Any injury to any layer will make the display of the screen flawed. Although most laptops have been tested for the pressure resistance of the top cover and the number of screen opening and closing times when they are designed and delivered, incorrect use and transportation methods may damage your laptop screen early. In the process of transporting and carrying the laptop, pay attention not to compress the screen and top cover, which may cause the broken cable of the screen and the fragmentation of the top cover, which is also the most common screen damage.B. when closing the screen, do not place any foreign matter between the display screen and keyboard to prevent damage to internal components. A layer of cotton paper is usually included in the package of the new machine. You can also put this layer of cotton paper between the screen and keyboard of the notebook computer, so as to reduce the wear between the screen and the health cap. If your laptop uses a pointing stick, we also recommend that you remove the pointing stick cap and store it separately when you take your laptop out for a long distance, so as to avoid top injury to the screen. C. do not touch the screen surface with fingernails and sharp hard objects to avoid scratching.If dust is adsorbed on the screen surface due to static electricity, do not pat it with your fingers to avoid leaving fingerprints. You can buy a special wiping cloth for LCD to clean the screen and wipe it gently. Screen protective film we suggest that you stick it when you don't use the laptop and take it off when you use the laptop. This can effectively protect the chemical coating on the outer layer of the screen so that the outermost coating will not be oxidized prematurely. During the process of using the laptop, users should never easily point / press the LCD screen with their hands or contact the screen with hard objects.If you often don't pay attention, scars such as white prints will appear on the LCD screen for a long time, and you will regret at that time. Many people use the habit of randomly pointing their fingers on the screen, which will not only leave ugly and difficult to clean finger marks on the LCD, but also the LCD is unfortunately marked by your fingernails, and your beautiful face will be colored. D. the laptop screen is the most conspicuous "face". If there is a stain or damage on it, it will definitely make the user very, very uncomfortable. So let's see how to beautify the screen? Do not use chemical cleaner (such as alcohol) to scrub the screen. You can buy a special cleaner for LCD to scrub.The cleaning method of LCD is similar to that of the shell. Except that it cannot be wiped with organic solvent, it cannot be wiped directly with water because the LCD has strong water permeability. If you don't want the screen to have color stripes due to water, remember this. You can wipe it with a wet cloth soaked in water or buy a special cleaner for LCD. Generally, the stains on the screen can be removed quickly. The following figure shows the effect comparison before and after cleaning.The screen is most likely to be contaminated with dust. Just brush it off with dry soft hair. You don't need more cleaning methods. However, if your screen is full of fingerprints, saliva (pointing out the consequences of rivers and mountains) and other unknown stains, you need some special cleaning methods. We recommend Sony's special cleaner for LCD screen (selling price about RMB 150), Friends who can't buy this kind of cleaner can also use high-grade glasses cloth and a little water to clean.Although the effect is not as good as Sony's special cleaner, and it's more laborious, it's always better than none. In addition, dust is adsorbed on the surface of LCD screen due to static electricity. It is recommended that users use a special wiping cloth for LCD screen to clean your screen, and please wipe it gently. E. moisture is the "natural enemy" of notebook computers. In addition to trying to avoid drinking drinks and eating fruit near the computer, you should also pay attention not to store the machine in a wet place.Serious moisture will damage the components inside the LCD. It is particularly noteworthy that in winter and summer, when entering and leaving a room with heating or air conditioning, a large temperature difference will also lead to "condensation". When the user energizes the LCD at this time, it may also lead to corrosion of the LCD electrode and permanent damage. Therefore, we also suggest that your ambient temperature change should not be greater than 10 / 10min. Once there is water on the screen, if you only find fog on the screen surface before starting up, gently wipe it off with a soft cloth and then start up. If the water has entered the LCD, put the LCD in a warm place, such as under a desk lamp, and gradually evaporate the water inside. In the plum rain season, we should also pay attention to running the laptop regularly for a period of time, so as to heat components and disperse the moisture. It is best to put a small bag of moisture-proof agent in the laptop bag to create a good home for loving the machine.If fog is found, wipe it gently with a soft cloth. If it has entered the LCD, the LCD must be placed in a warmer place so that the moisture and organics can evaporate. Powering on LCD with humidity can lead to corrosion of LCD electrode and permanent damage. Because the LCD screen of notebook computer is expensive, its cost generally accounts for 30% of the cost of the whole notebook computer. At the same time, its physical characteristics make it the most fragile and delicate part of notebook computer.Therefore, it is the top priority for notebook computers with LCD screen. The LCD will be aged or even burned out due to long-term operation. Therefore: at ordinary times, it is necessary to reduce the possibility of exposing the screen to the sun. When using the laptop during the day, try to pull the curtains to prevent the screen from aging due to too high temperature after being exposed to the sun. when the computer is not operated for a long time, you can temporarily turn off the power of the LCD screen through the function keys on the keyboard, or set the window. Power management option, set the waiting time to 5-10 minutes, which saves power and prolongs the screen life.If you go out for a long time, you should simply turn it off, which can prolong the service life of the backlight. reduce the brightness of the display to a darker level. when the user does not need to use it temporarily, it is best to use the screen saver or display the black screen, which will not only save power, but also prolong the service life of the LCD. Due to the physical characteristics of LCD, its service life is much shorter than that of desktop CRT display. For example, in about two years, the display will be dark and yellow due to the aging of backlight and LCD. This requires you to pay as much attention as possible in your normal use. Don't adjust the brightness too high. In fact, the screen quality of many machines is very good now. If you adjust it too high, it will be dazzling.In addition, the power management option can be set to automatically turn off the LCD without operation, which can not only effectively prolong the life of the LCD, but also save some power when using battery power.

If you find that the notebook's display screen (TFT) is very dark when you turn it on, the contrast and dark notebook screen is still very dark and can't be seen clearly. That's the screen darkHow does the screen darken? There are four common situations:The first is the problem of the lamp tube. The aging or short circuit of the lamp tube will darken the display screen. If the lamp tube has a problem, it can only be replaced by a professional maintenance company. The aging and short circuit of the lamp tube rarely occur. The aging is generally due to long-term use or collision during use (the service life of the lamp tube in normal use can reach about 3 5 years). The short circuit is caused by the metal in the screen shell, If the screen shell is broken, use it carefully to prevent short circuit.The second is that the main board has no voltage for the high-voltage board. Problems, aging or short circuit of the main board will occur. Most of them can be repaired. It is not necessary to replace the main board.The third is the aging or burning of the high-voltage board, or the loosening and burning of the power connection line of the high-voltage board. The screen darkness caused by the high-voltage board is more common, because the high-voltage board works at high temperature for a long time, the chip will be easier to age or burn outThe fourth is the broken screen line, which is often the cause of screen darkness, because NB is folding. Opening and closing the screen too hard will wear the screen line, and frequent use will easily cause the broken screen line.Generally, problems with the graphics card will not cause the screen to be dark. Most of them are flower screen or no display. In addition to the replacement of the lamp tube, the replacement of a non original high-voltage plate may cause the dimmable brightness of the LCD screen to fail (the impact depends on the individual). Generally, the high-voltage plate can be repaired.Conclusion: generally, it is not recommended to disassemble and repair by yourself.

It is reported that Apple plans to use cheaper LCD screens on most iPhone models next year, while delaying the full conversion to high-tech organic light emitting diode (OLED) screens, which also reflects consumers' price sensitivity.According to the Wall Street Journal, apple is expected to launch an LCD model and two OLED models this fall, and the LCD model is expected to account for most of its iPhone sales. It is expected that Apple will continue to use LCD next year, which is completely inconsistent with the previous report of a complete transition to OLED.Apple announced in March that it was testing its internal microled screen.Apple's decision to insist on using cheaper LCD screens has brought more uncertainty to its screen suppliers; In addition, Apple's decision to produce its own screen endangers the interests of many suppliers.Since apple is not expected to use these products in its OLED screen, the shares of Apple's three LCD suppliers, including sharp, LG display and Japan display, have fallen sharply in the past year. Subsequently, when it was revealed in March that Apple was already testing its microled screen, the shares of many display suppliers, including Samsung, sharp and LG display, fell again. This also damages the interests of general display and Synaptics. After reports showed that Apple would use more LCD screens than expected, the share price of general display company, which provides OLED display materials, began to fall.The Wall Street Journal pointed out that Apple's decision to postpone the implementation of OLED screens does not necessarily bring opportunities for LCD suppliers. For example, LG display has planned to invest in OLED screens.Apple has been facing the problem of supply shortage in the past. If suppliers have to change their production plans, Apple may face supply shortage again. It is reported that Japan display raised $320 million in April to meet the expected demand for its advanced LCD.According to recent reports, Apple has communicated its transformation plan to its suppliers, including plans to reduce parts procurement from suppliers by nearly 20% this year. At the same time, the uncertainty of the continuous expansion of Apple's supply chain will also make the new iPhone more expensive than ever.
