Linux can also be beautiful

Some of my friends around me still seem to have the impression of Linux on the dark command-line interface. When I told him or suggested him to use Linux, I would be surprised and ask me, how to use it (for development or daily use)?

Linux has a graphical interface

desktop

starter

File manager

set up

This is the "domestic" operating system deepin, which I have used for nearly two years. I don't know whether the interface is beautiful. I'm sure it can be used.

For other Linux, please refer to:

These are just my daily use, and many excellent software are not listed.

As for whether it can replace Windows, the problem varies from person to person. For me, in my two-year experience, I haven't encountered any problems that can't be solved under Linux, so I have to go back to windows.

Besides, I can't. There are virtual machines.

Running Android applications under Linux

Xdroid enables Android applications to run on Linux, greatly expanding the Linux ecosystem.

Yes, you are right. It is not based on virtual machine or simulator. It has considerable speed and takes up less resources.

This seems to be something windows can't do at present.

What are the advantages of Linux?

The cost of moving from one system to another is huge. What is the charm of Linux worth doing?

Linux is elegant

When I install a software under windows, I first need to open the browser, search the software you want, and carefully avoid advertising. When you find a website that looks right, you still have to carefully find the download address rather than the huge download button. Finally, when installing a small wing, you must not miss some checks, Once you accidentally miss it, you will find that the computer seems a little stuck. Soon, its friends will appear on your desktop.

Under Linux, commands such as apt install or Yum install can complete the whole installation.

Linux does not need to choose whether to put the software on Disk C or disk D. It has defined which files should be placed in which places,

You don't need anti-virus software,

There's no need to clean up the garbage,

There is no need to free memory,

There is no need to activate the system. It is open source and free,

No disk optimization is required,

No annoying pop ups,

There is no forced update.

Linux is efficient

This is what attracts me most about Linux

command line

The command line is not a backward way to manipulate computers. On the contrary, it has always been efficient and expressive.

When you want to copy, cut or delete a file, I believe there is no command to open the file manager and jump between different windows.

When you want to check the system running status, I believe that moving the mouse, right clicking and selecting task manager is not as fast as a command.

When you want to write a simple script or file, I believe that there is no command to open the editor, create a new file, write, select the file location and save.

...

The mouse is a good tool, but it has its limitations. After all, it has only three buttons. The expressive power of using parameters on the command line is infinite.

Reduce mouse use

Through the command line, the vimium plug-in of the browser (operate the browser interface in a way similar to VIM), Albert (call an input box through the specified key to open app, file, URL, direct search, calculator...), system shortcut and idea (its design idea is keyboard first), I can rarely use the mouse.

Of course, the mouse is not hot. When your hands hit the keyboard quickly, using the keyboard directly is faster than moving your right hand to the mouse and back, and this uninterrupted experience is very comfortable.

As for why this is the advantage of Linux, in my past years of windows experience, I have not found an entry to customize the system shortcut keys, let alone customize macros. Of course, windows also has a command line, but I think its command richness and cooperation between commands are not as good as Linux (some people call it an accessory).

Reduce duplication of labor

I have a folder dedicated to all kinds of scripts I write. Most of the time, your problem can be solved by the software on the market, but when there are some small, unique and repetitive tasks. Scripts can help you solve these problems.

For example, I have a script to monitor the production environment (in fact, it should come with the project itself), an OA Guardian script (in fact, it is to monitor whether I write a daily report or send a text message to remind me if I don't), and even a script to send wechat regularly

These scripts can solve the repetitive work in the information world to a certain extent, and let me focus more on creative work.

Starting speed

On my computer, both the system startup speed and the software (idea, chrome) startup speed are slightly better than windows.

There is no accurate test data based on use experience. However, idea has been measured, which is faster than a second

Memory usage

Linux is free

The above only explains the benefits of scripts, not Linux.

Because only Linux is so open and customizable, you can easily modify the system configuration and change the system state through commands, and even modify the kernel code, compile and use it.

If you don't like the current desktop environment, you can easily switch through commands.

If you love Mac OS as like as two peas, you can change Ubuntu to exactly the same way (including logo on boot).

If you don't like the file manager of the system, you can choose other excellent software, such as Nautilus.

If I don't like the current terminal, I have too many choices. I even used a terminal that imitates the geek style that appears in a movie.

On the contrary, take fonts for example. Under Linux, I can install and switch system fonts through commands, but there is no such setting or entry under windows. I don't quite understand why I don't have the right to choose.

And these are just trivial examples.

3 Reasons Why a Windows Screen Repair Company Is Better Than Others
3 Reasons Why a Windows Screen Repair Company Is Better Than Others
Sony A300 Compared to Olympus E-510 The Olympus E-510 was one of the most feature-packed DSLRs of 2007 and heavy discounting means it remains one of the best buys in the market. Like the A300, the E-510 has Live View and built-in sensor-shift stabilisation which works on any lens you attach. In its favour, the E-510's SuperSonic Wave Filter is the best anti-dust system we've tested, and while it may not eliminate all foreign particles, it does a great job of making them virtually impossible to see. And while its built-in stabilisation may not be visible through the optical viewfinder, unlike the Sony A300, it can be previewed on-screen. By using the main sensor for Live View, you will also see an exact preview of what you are taking. In its favour, the A300 has quicker AF in Live View, a tiltable screen which is also bigger at 2.7in, and a slightly longer 18-70mm kit lens. But while the E-510 may be out-featured in these respects, there's no arguing with its bargain price, especially with the twin lens kit which simply offers remarkable value right now.1. Why can girls have toys but men can't watch porn?I think you are perfectly right. Also point out that her "penis replica" is based on some REAL guy's REAL penis, so she is effectively having sex with someone else every time she uses it. I consider that far worse than porn - you are not actually having sex with anyone, just looking at images on screen2. Automatic AutoIndent while editing a Package (.wl)I recently found myself wanting a similar thing, that is, for the saved .wl to be formatted with the autoindentation and autospacing of the frontend's editor.The frontend will apply autoindentation for Input style cells in the Package stylesheet, so I first change the cell style from the default Code to Input (initialization cell).I found I can then capture the frontend's formatting by toggling the cell style to CodeText and back to Input. This inserts explicit spaces for autoindentation and autospacing in the cell, and upon saving the .wl file will be formatted similar to what you see on screen in the package editor.Programmatically, this can be done withHowever, this will leave the in-editor package with a bunch of redundant spaces, which should be removed, being careful not to delete spaces in comment blocks (* *) or strings ""In addition to removing redundant whitespace, this also replaces line endings with [IndentingNewLine]. This is necessary when opening a previously saved .wl file in the editor, since this will have line endings which means there is no autoformatting applied.3. Please help in my monitor dimensions?yes that sounds about right the screen is 22" but 1/2" is covered up by the frame to stop it falling out giving you a visual screen of 21.5 " you measure your tv and you will find that is also 1/2" smaller then it states 32" is actually 31.5" viewing screen4. How to change resolution on samsung series 6 hdtv?You can not change the resolution. The tv will only display what it is being feed. Keep in mind that you are not going to see any difference between 720P and 1080P is screen smaller than a 46". Hope this will help you out5. Which phone would you choose? Samsung Captivate Glide or LG Thrill 4G?Depends on what is important to you. The Thrill has 3D capability, the Captivate Glide has a keyboard. Also, the Captivate Glide ships with Android 2.3 "Gingerbread" while the Thrill ships with 2.2 "Froyo." Supposedly a 2.3 update has been promised by LG but for right now it has 2.2. The Captivate Glide uses a Super AMOLED screen that is very battery-efficient and has rich color saturation (rich to the point of inaccuracy but it looks great). The Thrill has a 3D LCD screen. I bought a Captivate Glide and am very happy with it. It's the most powerful keyboard Android phone available for AT&T (and I do not even use the keyboard all the time, since the on-screen Swype keyboard is excellent for short bits of text). The Thrill is a good value but you lose the keyboard, and you risk staying with Android 2.2 (which, among other things, does not have proper front-camera support and APIs). Apps have to be written to take advantage of 3D, and there are some, but not a huge number. But I would base it on whether a keyboard is more important to you, or a 3D screen.
LED Display Screen Has Become More and More Popular and Has Become One of the Important Display Windows
LED Display Screen Has Become More and More Popular and Has Become One of the Important Display Windows
There is no doubt that in the process of global economic ups and downs and industrial development and Reform in recent decades, China's LED display industry has walked out of a new path of "self-development, self driving and self guidance" with its courage, strength and endurance, and finally won the dominant position of the global LED display industry.1 China speedIn 30 years, we have completed the road of 50 or even 70 years of the same industry in other countries, which is the speed of China's LED display industry!At the same time, the speed of China's LED display industry is not only reflected in the "rapid development and rise" of production scale, but also in the learning speed of a series of new technologies, new models and new ideas "from reference to independent innovation". In the early stage of development, subject to the limitations of imperfect industrial chain, lack of experience of industrial workers and imprecise production and manufacturing process, China's LED display screen really belongs to "barbaric growth". However, after years of quality revolution within the industry and consumption upgrading in the terminal market, China's LED display manufacturing and innovation has led the global industry.2 Industrial Cluster"The world's LED display manufacturing looks at China, and China's LED display manufacturing looks at Shenzhen". A complete industrial chain of LED displays from raw materials, lamp beads, chips, packaging and supporting design has been formed in Shenzhen, China, as well as industrial clusters applied in various subdivided fields. At the same time, driven by policies and market demand in recent years, it has also been in Jiangxi, Fujian and other places, The establishment of new industrial bases and clusters has promoted the rapid development of LED display industry.From the LED display manufacturing in the midstream to the core components in the upstream and then to the channel retailers in the downstream, it can be said that China's LED display industry has established a terminal oriented "user-centered" market-oriented operation system and forced mechanism, forming a vertical integrated industrial layout covering all categories, so as to achieve faster speed and higher efficiency, Lead the innovation of LED display technology and products in the world.3 Scale costCompared with foreign enterprises, Chinese LED screen enterprises can produce LED display products with the same quality and performance at only half the cost. This is not cutting corners and shoddy goods, but based on China's complete industrial chain, efficient operation and management level, low labor cost and a series of advantages.Until today, although the cost advantage of LED display manufacturing in China is lower than before, China still has a great leading advantage compared with the world. Driven by the unique "scale cost" advantage of Chinese LED screen enterprises, LED display has become more and more popular and has become one of the important display windows.
Apple still Uses Cheaper LCD Screens and Decides to Produce Them by Itself, Endangering the Interests of Many Screen Suppliers
Apple still Uses Cheaper LCD Screens and Decides to Produce Them by Itself, Endangering the Interests of Many Screen Suppliers
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.

Will the LED Transparent Screen Become the "Darling" of the LED Screen Market?
Will the LED Transparent Screen Become the "Darling" of the LED Screen Market?
Led transparent screen is a popular subdivision screen in the LED field in recent years. We often see the figure of transparent screen whether it is glass curtain wall, glass window or shopping mall. As one of the high-end display products, the price problem of the original transparent screen makes many users can only wait and see from a distance.With the rapid development of LED transparent screen, its price has also decreased significantly to the acceptable range of users, and various spacing and special-shaped display products emerge in endlessly. Transparent screen is gradually emerging in the commercial display field because of its unique display style.Scientific and technological progress is the core of social development and the first productive force. The transformation and upgrading of science and technology has not only greatly improved the modern production capacity of enterprises, but also further improved human vision in social development. In recent years, with the strong support of the construction industry in big cities, the glass curtain wall area of commercial buildings has reached a new peak. In this regard, led transparent screen manufacturers have made major technical upgrades to the transparent display scheme of large-area glass curtain wall. As a provider of indoor and outdoor LED transparent screen display solutions, Shenzhen Jingang vision is also very happy to contribute to our strength under the mainstream of this market.In order to expand the scope of commercial display application market, we continue to integrate new technologies and introduce various innovative technologies, products and solutions to the market. In recent years, led transparent screen solutions have become more and more common due to the use of advanced technology and most market participation. This popularity has also prompted the outbreak of urban commercial exhibition industry, which is also due to the continuous improvement of infrastructure and the rapid development of urbanization.When it comes to transparent screens, the market segments are relatively broad, and the market segments are based on products, technologies, components, display types, screen sizes and application scenarios. Based on various segments, led transparent screen can help enterprises choose growth niche market and strategic development, and determine the difference between the core application field of products and the target market.
Principle of Touch Screen Capacitance Screen_ What Are the Application Areas of Touch Screen
Principle of Touch Screen Capacitance Screen_ What Are the Application Areas of Touch Screen
Principle of touch screen capacitance screenTouch screen is the most friendly computer user interface at present. It is more and more widely used in consumer electronic products. The touch detection device and touch screen controller are good. The mechanical structure of the detection device is damaged in the process of touch screen device, resulting in the decline of touch accuracy and shortening of service life of the touch screen; In addition, the cost of commonly used capacitive and resistive touch screens is relatively high. Inductive touch screen can avoid damage to the touch detection device during touch and prolong the service life of touch screen products.The working principle of inductive touch screen, as well as the hardware circuit and part of the program design of the controller, all of the controller circuits have passed the verification. The non-direct contact touch of inductive touch screen avoids the damage to the touch detection device, prolongs the service life of the whole touch control system, and the repetition accuracy and touch sensitivity of touching the same point meet the expected design requirements.The capacitive induction touch screen is not affected by dirt, dust or oil stains, but it will be affected by the surrounding environment to varying degrees because it adopts the electric field coupling principle. At the same time, the capacitive induction touch screen has serious drift phenomenon.What are the application areas of touch screenTouch screen has become a hot spot in the market. In the market, shopping malls, hotels and other places, it is still dominated by smart phones. The growth momentum of the smartphone market slowed down and entered a period of gentle development. The application of touch screen outside mobile phones, such as automotive electronics, retail, medical treatment, public facilities, leisure and entertainment, will promote the rapid growth of touch screen market.In addition to applications in large fields, touch screens can be innovated in subdivided fields. In the field of "pen writing tablet", innovate the touch screen.The products have been extended to tablet with pen writing function, e-book, all-in-one machine, electronic whiteboard, etc. And the pen and hand can be used at the same time. When one hand is touching, the pen can also write at the same time.The traditional materials of capacitive touch screen are ITO, metal grid, nano silver wire, carbon nanotube, conductive polymer, graphene, etc. Metal mesh and nano silver wire have more supporters. Both materials are metals (silver or copper) and their conductivity is better than ITO.
Screen Fingerprint Identification Will Be Applied to LCD Screen, Not Just OLED
Screen Fingerprint Identification Will Be Applied to LCD Screen, Not Just OLED
Fingerprint identification on mobile phones has become an indispensable part of our daily life.Especially during the epidemic, face recognition is mostly paralyzed due to wearing masks, and fingerprint recognition has become the current optimal solution.Of course, if you use a mobile phone without fingerprint identification such as iPhone x, you have to find a way by yourself...9to5mac also gave a tutorial on using face ID with mask Screen fingerprint identification has become the mainstream, and the technology is also very mature. However, Tony saw a news while surfing the Internet today, saying that Tianma, a domestic LCD and LCM design company, released the world's first LCD Screen multi-point fingerprint identification scheme (Ted finger print, referred to as TFP).The strength of this scheme is that the off-screen fingerprint identification mobile phones we use now are basically OLED screens, while the LCD screen basically has no on-screen fingerprint identification...One plus 6T off screen fingerprint identification diagram As we all know, the screen fingerprint unlocking needs the illumination of the light source for fingerprint identification, but the LCD screen is relatively thick and has poor light transmittance; Second, the LCD screen cannot emit light actively, and the backlight will interfere with the identification of optical fingerprints.These two problems make LCD basically bid farewell to screen fingerprint recognition.Therefore, mobile phones with LCD screen basically adopt side fingerprint identification, and some will be combined with the power key on the side of the mobile phone.But OLED screens don't have this problem. Because the OLED screen is thinner and more transparent, it is natural to use fingerprints on and off the screen.Then why do manufacturers not directly on the OLED screen, but want to operate madly on the LCD screen? The reason is also simple: because LCD screens are cheap...Although Lu Weibing, vice president of Xiaomi, said publicly some time ago that Hongmi team successfully realized fingerprint recognition under LCD screen on a redmi note8 Pro prototype, so far, no manufacturer has officially announced this technology, and Tianma is the first.So Tony was surprised when he saw the news. This fingerprint identification scheme can be said to break through the two obstacles of current screen fingerprint identification technology - LCD screen and identification area.If the multi-point fingerprint identification in the LCD screen can achieve mass production, it means that the LCD screen can also use fingerprint identification!Another point is the identification area of off screen fingerprint identification.So far, the identification area of screen fingerprint is basically fixed, almost at the lower position of the screen. People will subconsciously put their fingers at the approximate position when unlocking the mobile phone.But no one can guarantee that every time the finger is pressed on the fingerprint identification area, because the identification area is so large, it is inevitable that there will be deviations...The scheme announced by Tianma this time shows that it can make the whole LCD screen recognize fingerprints!Tony mended his brain, that is, I could identify my fingerprint and unlock my mobile phone by placing my finger anywhere on the screen.If this multi-point fingerprint identification technology can be mass produced, the efficiency of unlocking the screen will be much higher than now. You don't have to find the identification area and poke it on the screen.It can be said that Tianma's operation directly makes the LCD screen ride on the head of OLED in fingerprint identification. Once LCD screens didn't even deserve fingerprint identification. Now they not only have fingerprint identification, but also can identify 5 at a time...As for why the multi-point fingerprint solution in the TFP screen can realize these functions, high integration has played a great role.In short, it is to integrate touch, display and fingerprint identification, replace the previous design of fingerprint identification module and reduce the thickness of the screen, so that the screen fingerprint identification is feasible on the LCD.At the same time, in order to realize fingerprint identification on the whole screen, Tianma covers the whole screen with optical path and sensors.As for how multi-point fingerprint identification can play new tricks, it still depends on the subsequent operations of manufacturers.As for the fate of LCD screen after mass production of this scheme, we still don't know, but before that, LCD screen has never been the first choice for mobile phone manufacturers.After all, the OLED screen is thinner, can emit light by itself, and the color is more bright. The experience is much better than that of LCD, but there are still problems of stroboscopic and screen burning, and the price is relatively expensive.When it comes to the LCD screen, the advantages and disadvantages are reversed...The price of iPhone 11 with LCD screen is lower For most users, OLED screen is their first choice, but there are still a group of people who stick to the LCD screen.In addition to having a larger viewing angle, another reason is that they can't accept the strobe of OLED screen. They think it's really hurting their eyes...Therefore, once the TFP scheme realizes mass production, the defect that the LCD screen has no off screen fingerprint will be supplemented. If the price can be controlled well, the current situation of the screen in the mobile phone market may change a lot.However, before that, the mobile phone market was still dominated by OLED screens, not to mention the suoper AMOLED screens such as Samsung. The evolution of LCD screens has a long way to go...
What Is the Forming Process of the Flexible Touch Screen
What Is the Forming Process of the Flexible Touch Screen
Every day, new products, new experiences, professional membrane switch proofing factory, 12 hour expedited shipmentFrom the hot sale of Samsung Galaxy edge flagship series to the advent of various curved screen bracelets and TVs, it is no doubt that curved screen technology has been widely valued and sought after by consumers and the industry in recent years. In the future, with the continuous development and improvement of fixed curvature curved screen technology, the flexible touch screen that can realize arbitrary bending will become an important development direction. On the 25th, at the 13th International touch screen and display technology development forum, Huang Hanfeng, deputy general manager of touch R & D from Shenzhen oufeiguang technology, made a detailed introduction to the flexible touch screen from the perspective of the industrial chain around the four key elements of flexible display, flexible touch, flexible cover plate and flexible bonding.Flexible displayFor LCD display, the LCD is usually responsible for controlling the display gray, and the three primary color filters control the display color, which requires them to correspond one by one in order to display normally. If the LCD panel is used as a curved screen, the inner circumference and outer circumference will be unequal, and the original one-to-one corresponding liquid crystal and filter will have position deviation, resulting in color distortion. In addition, it will also cause a series of problems such as light leakage, dark screen ghosting and snowflakes. Therefore, for the curved screen, the OLED display technology represented by AMOLED has almost become the best choice.Huang Hanfeng said that at present, Samsung is the undisputed AMOLED overlord in terms of patents, production capacity, yield and technology accumulation. The sixth generation AMOLED panel that began mass production at the end of 2014 can now produce 50000 pieces per month, and the yield can reach 60%. The second is LG, but LG has been focusing on large screen curved TV. At present, with the increasingly obvious trend of small screen AMOLED, LG is also accelerating the layout of small and medium-sized flexible screens. Although its output is not as good as Samsung, its yield can also reach more than 60%. The latest release of Xiaomi note 2 is the flexible AMOLED screen of LG. In addition, Japan's JDI and sharp (already acquired by Hon Hai), Taiwan's Youda, domestic BOE, Rouyu and other screen manufacturers are also accelerating the layout of their own AMOLED technology. It is the general trend for AMOLED to replace LCD.Flexible touchIn terms of touch control, ITO (indium tin oxide) transparent conductive film has become the most important touch layer material for display screens such as non curved LCD and OLED due to its good light transmittance, low thickness, excellent hardness and conductivity, mature manufacturing technology and many other reasons. However, as ITO itself is a brittle material, it is not suitable for making flexible touch layer with large curvature or even free bending, and the cost and cost are high. At present, it accounts for about 30% - 40% of the cost of the upstream material part of the whole touch screen industry, and uses "indium", a rare metal with limited reserves. Therefore, with the advent of the era of curved surface and flexibility, it is likely to be replaced.Huang Hanfeng said that at present, the main substitutes for ITO materials are graphene, carbon nanotubes, nano silver and metal mesh. Graphene and carbon nanotubes are very good substitutes for ITO from the characteristics of the material itself. However, graphene is still in the R & D stage and is still far from mass production. The industrial mass production technology of carbon nanotubes is not perfect, and the conductivity of the thin film products made of carbon nanotubes is not as good as that of ITO. Therefore, from the perspective of technology and marketization, metal grid and nano silver technology will be the protagonists of development in recent years. Metal grid technology has been applied in some PC display markets.The metal mesh technology mentioned here is a conductive metal mesh formed by pressing metal conductive materials such as silver and copper or oxides on thin film substrates such as pet. Its main advantages are low raw material cost and good folding ability. However, due to the problem of Murray interference ripple caused by yield, output and high-speed pixels, it is more suitable for desktop all-in-one computers, laptops, televisions and other products with low resolution and relatively long-distance use.Nano silver technology means that nano silver ink material is coated on pet or glass substrate, and then laser lithography is used to depict the conductive network of nano silver wire. Its main advantages are high yield, small linewidth, good conductivity and folding resistance, while its disadvantage is high cost. Moreover, compared with metal mesh, nano silver material has smaller radius of curvature and small resistance change rate during bending. In addition, due to the linewidth, it is more suitable for high-resolution close-up scenes such as mobile phones, smart watches and bracelets."By comprehensive comparison, I think nano silver has more advantages than metal grid," Huang Hanfeng said.Flexible cover plateIn order to bend at will, in addition to solving the flexible display and flexible touch, the last and most critical part is the flexible cover plate and fitting. However, due to its hard and fragile characteristics, glass cover plate is not the best choice in the field of flexibility.Huang Hanfeng said that compared with glass, pet and PI (polyimide) materials with high surface hardness and high light transmittance are better choices, but at present, pet and PI also have many problems to be solved. On the one hand, they are not resistant to high temperature and have poor light transmittance: pet and PI will have problems of partial melting and property change at low ambient temperature, and they do not have good light transmittance compared with glass.Secondly, it is difficult to achieve a balance between hardness and folding. Huang Hanfeng said that if you want to meet certain hardness requirements, you need to apply the hardened layer, but after coating the hardened layer, after repeated folding, the hardened layer will crack and reduce the hardness. Therefore, how to achieve a balance between the two is the biggest bottleneck at present.Compared with the flexible cover plate that needs further development, the 3D glass cover plate necessary for curved screen mobile phones has a very good development prospect.Some data show that 2018 may become the outbreak year of 3D glass cover plate. It is expected that the mobile phone penetration rate of 3D glass cover plate will exceed 50% around 2020. With the maturity of 3D glass cover plate processing technology and the decline of unit price, the penetration rate will further improve. It is expected that the market scale will reach more than 19 billion yuan in the future.Huang Hanfeng said that the common manufacturing processes of 1R (single radian bending) and 2R cover plates have been basically mature. They basically achieve a bending effect through hot bending technology. The difference is mainly in the coating of hardened layer. However, the yield is a problem to be solved, which is basically only 30%, and there is no room for improvement in the short term. If 4R is to be done in the future, the yield will be lower. Therefore, the yield is one of the urgent problems to be solved in the manufacture of cover plate.Flexible fitAfter the cover plate is selected, it is fitted, that is, the cover plate is integrated with the touch and display layer below to form a complete module. At present, there are two common methods: roller type and vacuum bonding: the roller has high efficiency and needs to roll the pasted object. The efficiency of vacuum type is relatively low, but it does not need to roll the pasted object, so it is not easy to cause damage to the pasted object.Huang Hanfeng said that if the curvature is large, you can only choose vacuum bonding. However, for the possible 4R bonding in the future, due to its special four side bending characteristics, it is difficult to avoid wrinkles and bubbles in places with large radians even if vacuum is adopted. At present, the industry has adopted customized extrusion airbags or plastic parts to alleviate this problem, but it has not been completely solved. Therefore, the industry still has room for progress in multi surface and high curvature fitting technology.Huang Hanfeng frankly said: "from the perspective of the supply chain, it will take several years for the flexible screen to really realize mass production. At the same time, it also needs the upstream and downstream supply chain to jointly overcome the relevant technical problems."For future development, Huang Hanfeng believes that the integration of various modules will be the general trend. He said: "in the incell technology of LCD, ITO touch film and liquid crystal layer are integrated together, which is a good integration. Now the fingerprint module is independent, and it can also be integrated with touch in the future. I think there will be a process of mutual integration and progress between functional modules in the future."
LG Will Mass Produce Mobile Phone Flexible Screen in the Fourth Quarter of This Year
LG Will Mass Produce Mobile Phone Flexible Screen in the Fourth Quarter of This Year
In the early morning of June 20, Beijing time, according to the English version of Korea Times, in order to further consolidate the leading position in the display market, LG display will mass produce a new version of smart phone flexible display from the fourth quarter of this year and provide it to major customers.LG researchers and technicians said that the purpose of producing flexible display is to meet the growing demand for innovative solutions. LG spokesman Frank Lee said that the company is trying to meet the rapidly growing market demand for advanced display screens. Li stressed that the new display screen is foldable and not fragile, and the product will become a major innovation in display technology.LG said it was investing in flexible displays and high-tech panels for mobile devices, namely OLED panels that support high-definition (UHD) displays. "We have completed the development of the first flexible display and will start mass production from the fourth quarter of this year," LG said in a statementThe E2 production line of the company's display manufacturing plant in pozhou, South Korea, will be responsible for the production of flexible displays. LG said that the OLED flexible display will adopt generation 4.5 glass cutting technology, and the monthly production capacity of the production line will be 12000 pieces.Koo Bon moo, chairman of LG, hopes to revive the enterprise by launching leading products. Therefore, as a major shareholder of LG display, LG Electronics will launch its first flexible display smartphone later this year.LG predicts that flexible display may become the latest trend of mobile devices, so the company may also consider selling flexible display to major mobile device manufacturers.It is reported that LG's competitor Samsung display is also developing similar products. At present, Samsung display is testing flexible display products to improve product quality. Due to manufacturing problems, the upcoming Galaxy note 3 should not be configured with a flexible display in the short term.Kim Yang Jae, an analyst at Woori investment securities in Korea, said: "mobile phone manufacturers are increasingly pursuing bright images, beautiful shapes and thin display screens, while flexible display screens cater to this demand. LG display is expected to help them seize a greater market share." Kim said, LG's strategy of switching to flexible display can break the industry conventions and make the company earn stable profits.In fact, flexible display is only one step for LG to invest in different businesses and seize the global market share of OLED. LG is the first company to mass produce OLED display and foldable OLED screen. At the same time, the company is also developing OLED TV supporting high-definition display.Lim Joo soo, manager of LG OLED Technology Strategy Department, said that in order to remain competitive, LG is trying to reduce costs, reduce power consumption and improve image quality. Lim Joo soo said: "LG display is developing high-definition OLED TV screen. In order to improve the brightness, we plan to replace the existing 'bottom light' technology with 'top light' technology. In addition, the company will develop new materials to extend the service life of OLED display."In the next few years, OLED TV will become the mainstream product, and LG plans to expand the TV screen size to 65 inches and 77 inches. LG said that the above two OLED displays will be produced by the M1 test production line of pozhou factory.
