Does Anyone Know What to Use to Clean a Hd Plazma Tv Screen with Thank You?

Can the LCD TV screen be repaired1. If the damage is slight and the screen can still display normally, but the interface or cable is damaged, it can be repaired by replacing a new interface or re fixing the cable;2. If the screen is seriously damaged, broken or broken, and the screen cannot be displayed normally, you need to contact the after-sales service of the TV to replace the screen.Generally, the screen of LCD TV is the key component of ZD TV. The price of replacing the new screen is almost the same as that of purchasing a new machine. If the TV has been used for a long time, it is suggested to buy a new machine again, which is more cost-effective.Usual maintenance methods of LCD TV1. At ordinary times, if you need to place LCD TV, you must pay attention to handle it gently, because the LCD TV machines are relatively fragile. Once they are subject to a large collision, they will fail. In this way, it will bring inconvenience to you, so we must pay attention.2. When using the LCD TV for a period of time, you must pay attention to the cleaning of the screen, which can well protect the LCD TV screen. It is recommended that you clean it once a week and wipe it with a clean cotton cloth. Use less effort to avoid damaging the LCD screen.3. The place where the LCD TV can easily enter the dust is the back cover of the TV play, so you can make a good cover for the TV. If you can't, you can go to the nearby handicraft workshop and ask them to make one for you. In this way, you can cover the machine after watching the TV every time.4. When the TV is used, it is best to watch it continuously for three and a half hours and have a rest for at least 20 minutes, which can greatly alleviate the workload of the LCD TV. If you use it recklessly, the LCD screen will be damaged, and this damage is irreversible and cannot be repaired.

This is called AirPlay Mirroring. How to use it on a second generation Apple TV or higher can be found on Apple's site here and here1. How much will it coast to replace the screen in my iMac 24 inch screen?Is it rly too hard for you to go to apple.com and look yourself? it must have been 1000 times easier to come and log in to yahoo come to answers then click ask a question write your question. click preview click submit wait a while to hear a stoopid answer that may not actually help you and cry to your stupid self in frustration... (sounds sooooooooo much easier) Additional answer: dude just do a little research. no one on yahoo knows where you live so how the hell would they know if a little shop or repair place is close enough for you to take it to. plus if you get it repaired using an online site u have to pay shipping which is expensive for computers. plus u could probably see if apple would repair it under warranty that i cant find out for you either. stop wasting peoples time on yahoo answer. (also if you knew anything about computers or apple apple usually does not allow other companies to replace or repair their products unless they are apple certified sooo ur almost pretty much stuck with them)2.

How does the wii wheel pick up yaw?The Wii Remote contains two separate and distinct motion sensing technologies in it. The more visible one is the IR Camera in the end of the Wii Remote (under the dark plastic panel), combined with the Sensor Bar. Realy, calling the Sensor Bar is rather silly, since it senses nothing. All it is are a pair of clusters of IR LEDs, with a cord to the Wii only to syphon off the power needed to light up those LEDs. The Camera picks up images of all IR sources (hopefully just the two from the Sensor Bar) and sends them wirelessly over the Bluetooth connection to the Wii. The Wii then can translate the positions of the IR dots in the image into the position the cursor should be at on screen. hat is all the IR Camera or the Sensor Bar are used for. The second, and more core motion sensing technology, is a solid-state accelerometer (there is another one of these in the Nunchuk as well). This is basically a small weight suspended from all 6 sides by springs, with some mechanism to detect how far away from the neutral position the weight is. It's pretty similar to the mechanism inside PC joysticks, but with a third direction added. This is how all gesture-type motion controls are handled.5. My thermostat only runs on on. Why?most likely you neglected to "tell" the tstat that it has to turn the fan on during the heat cycle.....some programmable tstats have to be set up for the type system they are on [heat pump,gas or oil furnace with central ac,etc]...the tstat might think that its controlling a furnace that has its own fan control to turn fan on/off. .....consult the installation instructions to see if this is the case...the "set up" is either "on screen" or there are dip-switches o the back........dan6. Multiplication issue on spreadsheetI am giving just a shot in the dark here (until you provide other exact numbers of the cells):When multiplying (and dividing) numbers and you see (and expect) on screen 2 decimals and you want to do further calculations with 2 decimals you should always use the ROUND() function. Internally these numbers could be different. On screen you could see 0.34 but internally this could be 0,335643564. When doing further calculations with this cell the internal number (0,335643564) will be used.You have two options. Do a ROUND() around your cell value or formula on 'Route Pay and Miles'!$Q$27 or do the round in your other formula. i.e. =IF($F25=30,G25*ROUND('Route Pay and Miles'!$Q$27,2)," ") where the ,2 are the expected decimals.

What's the best way to clean an LED screen?I only ever clean mine with a damp cloth and then wipe over with kitchen towel. I do the same with the tv screen and no scratches there------What kind of tv was most watched in the late 1950s early 1960s?Variety shows were popular; these were shows where guests would appear and do skits or short shows, talk to the host, and not much else. Ed Sullivan was one such show. Senor Wenchas (? spell) was on his show a lot. The Beatles debuted on his show. All TV shows were family shows; married people had twin beds in their rooms, no cursing, no blood and guts. Kids were innocent. Gunsmoke was a western that was very popular. Game shows like What is My Line were on. There were cartoons for kids. A kid'show was Romper Room, and another one had a puppet o'possum that would give "possum kisses" to the kids on the show. I had a heavy clear plastic film (much like a heavy clear plastic shower curtain) that I could apply to the TV screen and when they did a drawing on TV I could follow the lines with crayons and copy the drawing at my house! Very exciting to me------Breaking a TV screen for an art project?The tube may implode. Wear eye protection------2018 Expedition Rear Entertainment SystemI just figured this out for myself after trying to do it via the instructions above. I was missing the step where I had to use the arrows on the tv screen to scroll on to the screen to select the Bluetooth option and click on it. It then asked up front if I wanted to connect automatically.------Can't See the Movie? Here's How You Clean a Flat Screen TVOver time, your TV gets dirty. It might be dust and hair, greasy finger marks, splashes from coughs and sneezes, or worse. At first you may not notice the dirt, but as it coagulates and builds, you could be left thinking that your TV picture has got worse. Cleaning your flat screen TV is increasingly important in an era of heightened hygiene. Here's everything you need to know about how to clean TVs and monitors.Why Do You Need a Clean Flat Screen TV? A flat screen TV looks amazing when its clean. But when its dusty and grimy the picture quality suffers and so does your enjoyment. Dusting the TV daily is wise as it ensures the TV works at its optimum capability. Excessive dust leads to heat build-up, which can result in poor performance. This is particularly relevant to smart TVs, which are essentially computers.Grease and splashes can potentially prove more dangerous than dust, however. Coughs and sneezes can end up landing on a TV if not caught; grease can harbor bacteria. TVs might not be as bad as remotes or game controllers when it comes to the inadvertent collection of bacteria, but they are still not good. So, a flat screen should be: Free from droplets from sneezing and coughing Now that's clear, here's everything you need to know about how to clean a flat screen TV. What You Need for Cleaning a Flat Screen TV What do you use to clean a flat screen TV? Before you start, make sure you have: A soft microfiber cloth: It's important that you do not use paper towels, tissue, or rags as these can cause scratches on your TV screen. If you do not have a microfiber cloth, an anti-static microfiber cloth such as the type used to clean eyeglasses and camera lenses, etc., can be used.Distilled water spray: This should suffice for most cleaning. Distilled water and soap spray: For tough grime, a mild solution of soap and water can be used. Panasonic recommends a very mild 100:1 ration of water to detergent for its screens. Antibacterial spray: this is optional, depending on how clean you want to go. While you would probably discourage people from touching the TV set, it does not hurt to ensure it is bacteria-free.Incredibly, that's all you need. How to Clean Your LCD/LED/OLED TV Screen Ready to clean your TV? Here's what you need to do: Turn off the TV. For safety, also unplug the unit from the mains electric. With the cloth, wipe the dust from your TV screen. You should also dust the sides and back of the TV. For greasy marks, spray the cloth, then wipe in small circles to loosen the dirt. It is vital that you do not spray the TV, as this can cause complications with the interior electrics. Tough muck? Use the water and soap spray, again spraying the cloth before wiping the TV screen clean. Finally, if you are planning the deep clean, wet the cloth with the antibacterial spray. Wipe this across the screen, around the edges, buttons, and anywhere else that may be touched. Your TV is now clean.Give it a moment to dry, then switch it back on. Own an Old Tube TV? Here's How to Clean That Need to clean an old TV? Old fashioned, pre-2005 TVs are typically cathode ray tube (CRT) screens, most often still used by retro gamers and some old computer systems and servers. Some later CRT models had flat screens, too, mostly for picture quality and aesthetic purposes. Surprisingly, these glass screens are easier to clean than flat screen LCD and plasma sets. The glass screen means that you can use window cleaner.What you need is: Standard window cleaner. If you do not have any, make your own with a white vinegar/water mix of one-part vinegar to two-parts water. Suitable, glass-friendly cloth. This should be clean and dry before starting. Switch off the TV and unplug from the wall. Wipe the set down with the anti-dust cloth. Spray the window cleaner onto the cloth. Polish the screen as you would a window. Leave to dry for a few moments. When you switch the old TV back on, the picture should look clean and bright once again. If you've taken the time to clean your TV and make it dust, dirt, and germ free, it makes sense to consider the remote.Prone to gathering sweat and dead skin, dust, splashes from coughs, sneezes, and drinks, not to mention crumbs of food, a TV remote control is positively filthy. Sadly, taking remote controls apart to clean them is not straightforward. If the device has bubble buttons, then wiping it clean should be straightforward. However, the type of remote control with rubber buttons is harder to deal with and for a full deep clean requires disassembly. There is not a standard way to do this as all remotes are different, but it's worth researching.Until you've found how to disassemble the remote control, tap it face down on the edge of a table. This will dislodge any loose crumbs and dirt before you wipe it down with a lightly dampened cloth. Again, consider antibacterial spray for the deep clean approach. Related: How to Clean an Xbox One Controller Now You Know How to Clean a Flat Screen TV Cleaning your TV is surprisingly straightforward. These steps will work on typical LCD and AMOLED flat screen TVs, as well as plasma televisions.Furthermore, you can use the same techniques (but with different cleaning solution) on old tube-based flat screens. With a clean flat screen TV, you can finally sit back and enjoy crystal clear shows and movies, as good as the day you bought it. But do not leave it too long next time. Establish a regular routine to keep your TV clean of dust, dirt, and disease-causing bacteria.

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.

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.

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 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.

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...

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."
