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"
