What If the Display Screen Is Distorted

Panasonic's vision for the future of autonomous driving is complete with surface-top 4K tablet displays, smart materials, and augmented reality.The firm revealed its Autonomous Cabin Concept at CES in Las Vegas, showing how driverless cars could soon allow your vehicle to be just like your living room.The concept not only aims to make the passengers' experience more enjoyable, but they say it could also make mobility much safer.Scroll down for video Exhibitors from Panasonic Europe at CES told Dailymail.com that the futuristic technology on display could be integrated into any autonomous car.Inside of the sleek model showing off the Cabin Concept, the exhibitors demonstrated the large, four-tablet table that could sit in the middle of a vehicle.Each display screen is roughly 20 inches wide.This would act as the main interface, exhibitor Roberto Vecciu told Dailymail.com, and would be 'where all the information flows.' The system combines 'infotainment' with connectivity, and each individual panel can be used on its own - or, a family on a road trip could open up a four-player game and all play at once.As it would work in a fully autonomous system, the 'driver's seat' is turned around to face the back of the car, as is the front passenger's seat.With this design, four passengers can sit around the large table in the center.On a long trip, kids could use individual screens to stream videos or music, while parents could check emails and do work, he explained.But, it has safety purposes as well.The screens would display any incoming alerts detected by the outside sensors, allowing the passengers to be aware of any potential hazards on the road.Along the side, the concept car also featured a stunning LED display, which the exhibitor explained could be fine-tuned to meet the needs of the passengers.A smart disk placed on one of the screens works like a knob, and when turned, it could be used to change the LED lights and brightness level or adjust the interior temperature, for example.The car even comes with a smart metal cup in the cup-holder, which can reveal different properties - like calorie count - about what's inside of it, when placed on one of the display screens.All of the technology inside is essentially ready to go, the exhibitors explained, and now only waits on a fully autonomous vehicle that could host it.According to Panasonic Europe, the design could one day make 'traveling in the autonomous car of the future as fun and as important to everyday life as a smartphone is today.'

Have you recently gotten your phone wet?... either way yes, when I worked for Verizon Wireless, our first step of troubleshooting would be to take out the battery for about 1 minute, then try to power it on if that does not work, you should call your provider, from verizon that is 611 from ur phone. but again it sounds like it might have gotten wet, not necessarily dropping in water, if you have it in the bathroom while you shower it can get condensation in it, or if it is by the sink when running water it can get splashed. Good luck1. Utility to display on screen the currently pressed keysQiPress seems to work for me.There is a lite and a pro version at $30. The lite version is enough for my needs2. Vehicle navigational systems and display screen sizes?1. All the companies that make GPS units for both the car and the independents all use the same mapping systems..... 2. The Garmin Streetpilot 7200 has a 7-inch screen and runs between $500.00 to $1100.00 dollars. 3. The Kenwood DNX7100 has a 7-inch screen but it runs between $899.99 to $1,399.99 depending on which store you buy it from.3. How do I set my display screen back to normal? After I used an old, damaged VGA (15 pin) cable?Open Display Settings by clicking the Start button, clicking Control Panel, clicking Appearance and Personalization, clicking Personalization, and then clicking Display Settings. Mess around with the resolutions here and also make sure the correct Display is selected (TV or your LCD Screen)4. How do I take a shot without the volume display on screen?I have battled this issue ever since they pushed Android version 4.2.2. On my Galaxy Tab model GT-P5113 the power volume down would work only about once every 10-20 attempts. Since the new build was pushed last week I checked it again. Now the screen shot does not work at all. But I gave up long ago and came up with a solution. I use my Samsung Victory telephone to take a picture of the tablet and send that to the tablet to by whatever share method is handy.5. When I turn on my digital camera, the words on the display screen are: warning! this cf card cannot be read.??Also make sure you have not inadvertently locked the card. There is a little slide switch on the side of the card. It should be in the UP position6. Why do people have to literally poke the display screen with their oily finger, can't they just glide over without touching it?I tried and it does not appear that way, no. The touch screen does not respond to gliding your finger near the screen, you have to touch it.Unless you are referring to a non-touch screen phone or computer where someone is just pointing and then touches the screen. I imagine that's because they misjudged the distance, or because they did not realize how oily their skin is7. Can you buy a replacement display screen for a motorala razr?properly it extremely is rather a consumer-friendly challenge w/ the silver RAZRs. First you may desire to take out the SIM card and placed it back in returned. If that does not help, you may desire to touch Motorola. good luck!.8. What can I use to clean my laptop display screen?microfiber cloth LCD cleaning solution.9. Why are mobile phone manufacturers not making an infinity display screen in a 4.5 inch device?The small screen may be something that people like you would like to have; but you are in the minority. The trend now is the big screen and people actually voted for this with their wallets.Even Apple could not fight off this trend and kowtow to the demand of the people, hence all Apple phones are big now. It still has a small phone for sell but not that many people buy it10. My 1st generation iPod display screen is partially blank. Why?Timed obsolescence. They know damn well that you are gonna spend the bucks and buy a new one. If it lasted forever, they would be outta business11. My iMacs Display Screen Fell downYou have two distinct problems with your iMac that you are unfortunately conflating with the most obvious damage - the broken display. The display is most likely broken and will need to be replaced. I can be tested, but not in a typical home or office environment. The cable connectors on the logic board may be damaged as a fall like that will literally rip them off the board. A visual inspection should be enough to verify if they are good or notThe fan spin is likely because you replaced your hard disk with a non-Apple one that does not have a temp sensor. A missing sensor will cause the fans to spin at full speedThe slow performance is likely due to the erroneous temp readings (from the missing sensor) and the Mac thermal throttling in response. To fix the fan and speed issue, you simply need an inline temp sensor to send the correct data to the SMC. However, the screen is quite expensive and you should get a quote on a replacement prior to doing this - it may be much more cost effective purchase a replacement iMac of the same vintage and sell that one for "parts."Also, if you are going to replace a HDD and go through all the trouble on an iMac, you should spring for an SSD. The performance gains are well worth it

As we all know, iPhone x is Apple's first mobile phone with OLED screen, and the screen of this mobile phone is provided by Apple's competitor Samsung. However, this situation may change in the future. It is understood that Apple will design and produce its own display. It uses a facility near California to produce a small number of screens for testing. Apple is investing in the development of the next generation of microled display, the secret project code t159.Apple will develop displayApple has a secret manufacturing plant near its California headquarters, which is currently producing screens on a small scale, mainly for testing purposes, the person familiar with the matter said. Apple is investing heavily in the development of the next generation of microled displays. Compared with the current OLED screen, microled is expected to make future electronic devices thinner, clearer and more energy-saving.People familiar with the matter said that the production difficulty of this screen is much higher than that of OLED display. About a year ago, apple almost gave up the project. But later, the engineers made significant progress and put the project into an advanced stage. Still, people may have to wait a few years to see Apple's R & D results.Last November, it was reported that Apple was designing its own iPhone power management chip, which will be enabled as early as 2018. "According to Apple's current plan, about 50% of iPhone power management chips will use their own products from 2018," the report said. Moreover, the plan was confirmed by the supplier dialog.In addition to the power management chip, apple is also developing its own GPU chip. Imaging technologies, Apple's GPU chip supplier, said in April last year that it had received a notice from apple that it was developing its own GPU and hoped to have greater control over its products. To this end, Apple will stop using the GPU technology of imaging technologies and terminate the payment of patent fees.Last September, foreign media also quoted a number of insiders as saying that Apple plans to develop its own processor for Mac laptops to replace the current Intel processor.In addition, Apple announced last December that it would invest $390 million in Finisar, a supplier of iPhone x laser chips.In February this year, it was also reported that Apple was negotiating with the miners, hoping to purchase the core raw material "cobalt" required for iPhone batteries directly from the miners, so as to ensure an adequate supply of such battery raw materials.Apple developed the display screen because of itIndustry insiders said that the purpose of Apple's move is obvious, mainly to reduce its dependence on Samsung's screen. At present, Apple's electronic products mainly use Samsung's screen. In order to control its products to a greater extent, Apple has continuously invested in new areas in recent years in order to reduce its dependence on component manufacturers.But an apple spokesman declined to comment.Now smartphones and other gadgets basically use off the shelf display technology. The apple watch screen is made by LG display. The same applies to Google's larger pixel phones. IPhone x is Apple's first OLED phone, using Samsung technology. Mobile phone manufacturers adjust their screens to their specifications, and apple has calibrated iPhone screens for years to ensure color accuracy. But this marks the first time Apple has designed its own end-to-end screen.The secret plan, code named t159, is supervised by Lynn young. The chief executive is Lynn young. He helped develop the touch screen of the original iPhone and iPad and is now responsible for supervising the screen technology of iPhone and apple watch.The 62000 square foot manufacturing plant is Apple's first of its kind. It is located on an obscure street in Santa Clara, California, 15 minutes' drive from the apple orchard campus in Cupertino, with some other unmarked Apple offices nearby. There, about 300 engineers are designing and producing microled screens for future products. The facility also has a special area for the complex process of "growing" LEDs.Another nearby factory has the technology to handle the so-called led transmission: the process of putting each pixel into the micro LED screen. In 2014, apple acquired the startup luxvue and inherited the intellectual property rights of the process.About a year after the acquisition, apple opened a display research laboratory in Taiwan (internally known as the "technology center"). In testing whether the company can realize the manufacturing of internal displays, engineers in Taiwan first built a small number of LCD screens using apple technology. They assembled it at the Santa Clara factory and converted it into a prototype iPhone 7. Apple executives tested them and then let the presentation team move on to develop Apple designed microled screens.The complexity of the screen manufacturing facility means it took Apple months to put the California plant into operation. It was not until recent months that Apple engineers had more confidence in their ability to eventually replace screens from Samsung and other suppliers.On December 14, 2015, apple building, Longtan, Taiwan.At the end of 2017, engineers successfully produced full-featured microled screens for the future Apple watch for the first time; The company's goal is to first provide new technology in its wearable computers. Although it is at least a few years away from consumers - assuming the company decides to continue - the production of functional microled Apple watch prototypes is an important milestone for companies that designed hardware produced by other companies in the past.The latest microled Apple watch prototype is not a fully operational wearable device; The screen part is connected to the external computer board. According to a person who has seen them, the screen is much brighter than the current OLED watch display, and engineers have better control over individual colors. Executives recently approved continued development over the next two years with the goal of transporting microled screens in products.People say the technology cannot be used on the iPhone for at least three to five years. Although smart phones are Apple's cash cow, apple watches first set a precedent for new screen technology. When it was launched in 2014, the apple watch had an OLED screen. The technology eventually migrated to iPhone x last year.Creating microled screens is complex. Depending on the screen size, they can contain millions of pixels. Each has three sub pixels: red, green and blue LEDs. Each micro led must be created and calibrated separately. Each piece of work comes from the so-called "donor wafer" and is then massively transferred to the microled screen. In the process, apple purchased these wafers from third-party manufacturers such as EPISTAR Corp. and OSRAM Licht AG, but has since "grown" its own LEDs to make internal donor wafers. The growth process was completed in the clean room of the Santa Clara factory.Engineers at the factory are also assembling a prototype microled screen, which is just connected to the glass. Backplane is the basic component of electronic display, which is developed by Taiwan factory. Apple is also designing its own thin-film transistors and screen drivers, which are key components of display components. At present, the Santa Clara factory can manufacture a few fully operable Apple watch size (diagonal less than 2 inches) microled screens at the same time.Until microleds are ready for the world to see, Apple will still - at least in public - bet on OLEDs. The company plans to launch its second OLED phone in the fall, a 6.5-inch giant phone, and is trying to expand Samsung's OLED production, including LG.

Whether driven by Moore's law or consumer demand, the required level of performance in today's TV may seem overwhelming. Compared with the standard definition television format (SDTV), the amount of data driven by the digital television with 1080 pixel high definition (hd) format is 6 times larger. It needs to manage digital television, IPTV, video conference broadcasting and process Dolby AC-3, MPEG and other audio formats. These functions have become the necessary functions of digital television (DTV).In terms of the highest requirements for audio, video and input signal formats, there are several viewing options: forward projection, rear projection, DLP, LCD, plasma and CRT. Whether watching TV on the 1-inch display embedded in the watch or watching TV on the whole wall with the display screen of the projection system, the requirements for the combination of size and performance are almost endless.Fundamentals of digital televisionEven though every TV on the shelf may be very different in size, appearance, shape factor and the basic description given to you by the salesperson, the basic construction modules of TV are very similar when you examine its interior.Generally speaking, digital TV can be divided into less than 10 main modules: display (and driver), core media engine, audio codec and processing, video codec and processing, tuner, interface module and power supply. The absolute performance requirements for each module are defined by the performance level of the comfort experience of your favorite seat.The following figure is a block diagram of a typical digital TV system.Figure 1: block diagram of typical digital TV systemIn Figure 1, we give the basic block diagram of HDTV, which we have considered at the functional block diagram level. Developing the TV system behind the screen requires many tools, which can be obtained from various enterprises. However, in the process of integrating solutions from different component suppliers, it is necessary to speed up the design cycle to shorten the time to market and ensure compatibility. Whether using DLP technology, DSP based digital media processor, other core processing solutions or some other high-performance analog components, it is necessary to design a highly integrated, flexible and easy-to-use digital TV for the rapidly evolving digital TV market. For converged applications, it is very important to design high-performance audio and video codec, graphics acceleration, communication and support functions into the home entertainment experience system.Video designConsumers often put forward very high requirements for video experience when watching TV. Because of this, resolution, brightness, contrast and clarity are important to the "realistic" experience. It is very important for TV to support a variety of ATSC TDV formats, NTSC and PAL decoding, composite and S-Video input and two-dimensional filtering. With the development of HDTV, supporting full HD with 1080i resolution equipped with 3D filtering will be the standard configuration. In the process of receiving the video signal chain shown in Figure 1, it is important to select a video decoder, analog-to-digital converter (ADC) and video buffer with the ability to mix various performances, so that you can adjust the performance according to the cost target of the system.Figure 2 Data stream path of video decoderFigure 2 shows the data stream path of the video decoder, which is responsible for processing NTSC, pal, SECAM, S-Video, SCART, YPbPr, RGB, 480p and other input formats. In digital TV, support for this level of flexibility is necessary, just to make a model work in any format after actual setting. Typical performance characteristics of digital TV decoder include synchronization, blanking, field, active video window, horizontal and vertical synchronization, clock, synchronous phase locking (for downlink video coding synchronization), main CPU interrupt and programmable logic I / O signal. This is a supplement to digital video output and for advanced vertical blanking period (VBI) data recovery. As an additional function, some video decoders support VBI data processor (VDP) for data slicing, parsing and error checking on text television broadcasting, transmission subtitles (CC) and other VBI data. The built-in FIFO stores up to 11 lines of text TV broadcast data, and appropriate main interface synchronization and full screen text TV broadcast recovery are several common requirements in today's system. However, some implementations require a decoder that can provide output formatted data at twice the speed of the sampled original brightness data for VBI processing based on the main CPU.For the ADC in the signal chain, PC and HD video output require improved jitter reduction performance, high image quality in the video system, and can support the increasing bandwidth demand. In the digital TV implementation scheme, an 8 / 10 bit three ADC usually provides a sampling rate of 165 MSPs, which provides rich video performance, and is also an ideal choice for commercial projectors, TVs and set-top boxes.Finally, the output resolution of the video signal chain should be matched with the performance of the display and the resolution of the input signal, so as to optimize the video design. In the era of low resolution CRT TV, it may always be acceptable to adopt a lower performance front end. However, with today's high-resolution display, any noise or irregular signal in the analog front end will be clearly displayed on the screen of digital TV.

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. 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 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...
