My LCD Screen on My Digital Camera Stays White?

sounds like you are up for another repair. Does your camera have a view finder? - use it while you are waiting for the repair. In the film days we never knew what we had until it was processed so we always shot 3 or 4 of our subject just to be sure. I still do that with my digital and I am usually not unhappy that I did. Try it.

1. Anyone know where i can buy cell phone parts.. my LCD screen broke.?

there is photonic radiation from the show reveal of a CRT show reveal. the tiers on the instantaneous at the instant are not important. Spending 18 hours an afternoon in front of the show reveal might have the comparable consequence as that quantity of time in front of a familiar television. in case you have an LED show reveal, there is not any radiation to complication approximately

2. Why do I see a white LCD screen on HP V5061u camcorder?

it is a problem with the processor which converts the image to the viewfinder to a valid image .. essentially the video processor has malfunctioned on the circuitry .. usually a dead camera. if your camera is under warranty , call them and lodge a claim , this will be the only fix for this particular problem. do not let them tell you what your options are , regardless of the price , your camera has a warranty to reflect the actions offered for this camera , unless there has been a particular waiving of your rights for post consumer advice . Deal Direct with HP in your local country , and keep the pressure on , and do not let them fob you off if you bought and have immediately bought the product back (from the store) , and there is no refund , nicely (as you can) tell the manager of the store you bought it from that you bought a DOA camera , and have quickly returned it , expecting a fair returns policy for electronic item purchased at this store , show your receipt (do not give them) and if they do not give a refund , or the same product , tell them that you are going to consumer affairs to ask them to follow up on the case .. once you have exhausted all store option work with HP in the for them to assist on a new replacement camera or repair .

3. I have just bought a new LCD screen, is there some sort of clear plastic guard I can buy that will protect it?

It is not really needed but if you feel you would be better with one then you can buy a plastic window pane to fit and use adheasive or clips to install it. I have one and have had fr over a year and have no cover for it. I clean it with water containing a small abount of detergent and then wipe it dry. Just be careful when cleaning and d not let water drip or run. Turn it off or unblutg it

4. just bought for my hdtv a lcd screen spray cleaner and came wit a cloth is this good????

Bill, how the hell are we supposed to know what you bought? A TV/electronics store will have screen cleaners - just make sure the cleaner is LCD specific! Unless you have a real problem with your screen, a soft, lint free cloth, very slightly dampened with plain water, is as good as anything

5. Is the Kindle Fire a tablet or an e-reader?

hi, Jacob, Kindle Fire is neither a tablet (too underpowered and lacks features) nor eReader (LCD screen and poor battery life.) It is rather a $200 device for shopping on Amazon web site. Take a look at recently released Nook Tablet - it's been getting rave reviews and it is the best device in it's class - much better than Kindle Fire. It's got Netflix, Hulu, Pandora, Angry Brids, etc., the best battery life, the best screen, double the RAM and space for apps/photoes/movies, microSD slot, a microphone for Skype, and physical volume controls on the side - neither is on Kindle Fire

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.

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...

1. Internal contamination: this kind of phenomenon is common. Customers often mix internal contamination with top scratch and think it is internal contamination. The general phenomenon is that there are small black spots, stains and chemical fibers in the segment code LCD. Refers to the presence of chemical fibers in the LCD.2. Rainbow: the segment code LCD screen of this kind of phenomenon is relatively serious. It is very easy to see the more serious ones. At first glance, it looks like a colorful rainbow. The lighter ones can be seen only by observing from different angles. This kind of phenomenon is mainly caused by PI or no adjustment during leveling.3. Cobwebs and small snowflakes: the segment code LCD screen of this kind of phenomenon is mainly that the electrostatic induction is not solved well or the LCD screen is not antistatic.4. Internal scratch: the general phenomenon is that there are black bars and a line in the segment code LCD screen, and the PI is scratched, mainly manifested as the wireframe.5. Color unevenness: the general phenomenon is that the color indicated by the segment code LCD screen is inconsistent, rainbow, that is, the color of LCD is uneven, and the middle rainbow or bar edge rainbow and its colorful patterns are uneven. The key is that in terms of color, this kind of may be caused by the uneven construction coating during the composite polarizer.6. Inconsistent background color: the general phenomenon is that the overall color of segment code LCD is very different from that of other LCDs. This kind of phenomenon is that the key customers have different background colors with different batch numbers after changing the dealer. It is best to produce them in batches, which is likely to lead to lower harm.7. Damage: the customer calls the glasses broken or broken. That is, part of the segment code LCD screen LCD is incomplete, including corner damage, edge damage and conductive layer damage (that is, one side of the pin is damaged, which is generally caused by many freight logistics elements, which may be caused by both enterprises and customers.8. Top injury and scratch: this kind of phenomenon is mainly caused by impact extrusion in the whole process of transportation, and it is also likely that customers encounter sharp objects after computer installation.9. Poor cutting crack of laminated glass: some bulges or dents are caused by Y-axis laser cutting and X-axis fragments. The key phenomena are cutting deviation, large cutting, small cutting and unfairness.10. Scratch on LCD pin: the pin side of LCD missing code screen (generally referred to as conductive layer) is scratched, resulting in short circuit and poor conductivity, which are easy to be caused by general customers during maintenance.11. Loose pin: this kind of phenomenon is more common for LCD segment code LCD screen. Due to the lack of code liquid screen, there is too little strong glue or polishing in the whole process of foot installation. When plugged in, it indicates that everything is normal. After a period of time, there will be a lack of painting. This kind of discrimination is very difficult. It may be a problem of IC or the pen segment code LCD screen.12. The LCD polarizer is scratched and punctured: the common phenomenon is that the insiders call it a mirage, and the mirror glass is blurred. That is, the polarizer is damaged or damaged by hard hands such as knife heads (which will be caused by customers' wrong placement and operation).13. Wave pattern of polarizer: there is a pattern on the polarizer, which can be seen only with LED backlight, because when the conductive layer stain is wiped with ethanol or toluene after the patch type, ethanol or toluene will penetrate, and the customer is also likely to penetrate when wiping the pin.14. No protective film: that is, the protective film on the surface of the polarizer is torn off. Generally, the IC is broken, and the LCD is considered to be broken during maintenance.15. Polarizer bubble: there are small bubbles on the surface polarizer of patch type rear LCD.16. Reverse pasting: it is called wrong pasting, which means that the polarizer is pasted reversely, but what should be pasted on the lower film is pasted on the upper film.17. Bumps, chemical fibers: dust, chemical fibers and other pollutants fall into the LCD surface or there are stains at the polarizer during the patch type.18. Polarizer etching: that is, the polarizer produces chemical changes with some liquid and is etched to fade or deform.19. Wrong materials: there are products of different types and characteristics infiltrated, wrong materials of different models and specifications infiltrated by revision, LCDs of foreign manufacturers and LCDs of different stages integrated, and the marks on the LCD conductive layer are used as the basis for judgment.20. Layering: there are 17 layers of polarizer in the whole process of composite type. If the composite type is not timely, there will be maintenance touch of many layers on the polarizer. In case of such problems, these batch of segment code LCD screens can not be applied. They must be pulled out and replaced again.fqj

If the LCD Screen Encounters Flower Screen Failure, How Should We Deal with It
If the LCD Screen Encounters Flower Screen Failure, How Should We Deal with It
LCD screen may encounter flower screen failure during use. The flower screen failure of industrial LCD screen may have an image, but the image is covered with dot, sheet, mosaic and other interference.If we encounter LCD flower screen, what aspects should we check? Generally, LCD flower screen can be processed from the aspects of checking signal source, logic board, LVDS signal, motherboard, screen parameter, LCD screen, etc. The specific process is as follows:1. The problem of industrial LCD screen cable arrangement is whether the cable connecting the screen and the main board is burned or loose. The interface should be plugged tightly to avoid short circuit or poor contact. In this case, just change the cable arrangement.2. Use a multimeter to check whether the power supply of the LCD is grounded. This may also be the reason for the screen flower. If there is a problem, just ground the power supply.3. If the LCD motherboard is broken, you can replace it with a new motherboard, but this probability is relatively small, but it is not ruled out. You can replace the motherboard and have a try.4. If the failure phenomenon of industrial LCD flower screen is irregular flower screen, the image in the middle of the flower screen is mixed with many small color dots. Corresponding maintenance idea: the LVDS patch cord is in poor contact.5. If the fault phenomenon of industrial LCD flower screen is that the stripes and colors of flowers change after repeated power on. Check logic board6. If the fault phenomenon of flower screen of industrial LCD is that the stripes and colors of flowers do not change after repeated power on. Corresponding maintenance idea: it is likely that the screen itself is broken.7. If there is interference in the image, there is also interference in the characters. Corresponding ideas: logic board, screen signal wiring, digital board signal output circuit.8. If the character is normal, the image has block and dot interference. YPbPr input signal, no interference. Then input from the AV port, and the image is disturbed. Corresponding maintenance ideas: false soldering of frame memory, broken control signal line of image enhancement processing IC.9. Industrial LCD screen flower screen fault phenomenon, if the images are all flower dots, finely broken flower screen, the characters are normal. Corresponding maintenance idea: the fault is in the video decoder circuit. Because the fault generated by the image enhancement processing circuit is massive, not fragmented.The above are the reasons why the LCD screen may flower. If the problem is still not found after troubleshooting, you can contact the LCD screen supplier and motherboard manufacturer to ask their professional technicians to troubleshoot the problem.fqj
Will the LCD Screen Be Equipped with Off-screen Fingerprint Identification Technology?
Will the LCD Screen Be Equipped with Off-screen Fingerprint Identification Technology?
Payment app fingerprint security authentication, joint account withdrawal encryption fingerprint authentication... Many fingerprint identification behaviors are expected to be realized in a way of higher security and convenience through under LCD screen (internal) fingerprint identification technology.Due to the opaque characteristics of LCD screen, it is difficult to realize this technology. Nevertheless, many panel and mobile phone manufacturers have challenged LCD off screen fingerprint technology, which is evolving towards high integration, full screen fingerprint multipoint identification and high screen share.Evolution from "off screen" to "on screen"At present, the off-screen fingerprint identification technology applied to OLED mobile phones has been very mature. Due to the high cost, the selling price of mobile phones is generally high. Although the cost of LCD screen is low, the LCD screen itself cannot transmit light, so it is difficult to realize the fingerprint technology under the LCD screen. Nevertheless, in recent years, many panel and mobile phone manufacturers have challenged the fingerprint technology under the LCD screen and achieved certain results.In May 2019, AU Optronics displayed a full screen optical fingerprint identification LCD screen.In June 2019, BOE revealed that the optical fingerprint sensing technology under LCD screen has been successfully developed. In August 2019, Huawei glory demonstrated the LCD mobile phone prototype equipped with off-screen fingerprint unlocking. It is reported that this prototype is the result of joint development between glory and BOE.In March 2020, Lu Weibing, vice president of Xiaomi group and general manager of Hongmi brand, announced that Hongmi team had overcome the problem of screen fingerprint, realized screen fingerprint on LCD screen and had mass production.In June 2020, TCL Huaxing announced that it had developed fixed single point on-screen fingerprint technology. It is expected to launch full screen single point on-screen fingerprint technology this year and Full Screen multi-point on-screen fingerprint technology in 2021.In July 2020, the world's first LCD on-screen multi-point fingerprint solution (Ted finger print) developed by Tianma was officially released. The scheme embeds the fingerprint image collector in the TFT display substrate, realizing the integration of touch, display and fingerprint identification.What is the evolution process from "off screen" to "on screen"?It is understood that the development of off screen fingerprint is mainly divided into off screen fingerprint (fixed single point), on-screen fingerprint (full screen single point), on-screen fingerprint (Full Screen multi-point Ted embedded), etc. Off screen fingerprint identification includes capacitive, optical and ultrasonic types. However, due to technology and cost, most of the products equipped with this technology can only realize single point fingerprint identification in a fixed area. Now, the latest R & D achievement - on-screen multi-point fingerprint solution adopts the optical fingerprint identification mode, integrates the fingerprint image collector into the display screen, and can realize "Full Screen multi-point" fingerprint identification on the full screen, which has a larger screen identification area than off screen fingerprint products.Integration and multipoint recognition become the direction of attack"The future development direction of on-screen multi-point fingerprint solution must be high integration, full screen fingerprint multi-point identification and high screen proportion." Wu Zhen, director of marketing department of Tianma Microelectronics Co., Ltd., said in an interview with China Electronics News.Specifically, the first is high integration. It is mainly to realize the three in one of touch, display and fingerprint identification. It is necessary to break through the limitation that the optical fingerprint in the LCD screen is difficult to match the thickness of the normal cover plate, so as to have more market competitiveness and mass production; At the same time, because the optical path modulation unit is integrated in the display screen, the thickness of the display screen is reduced by more than 50% compared with the external collimating optical path design scheme, making the design of terminal products lighter and thinner. The second is full screen fingerprint multipoint identification. To support full Screen multi-point fingerprint identification in any display area, it can be applied to full screen blind unlocking, APP encryption unlocking and user-defined fingerprint control to achieve high security and high privacy. The third is the proportion of high screen. The fingerprint identification function is built into the display screen to effectively improve the screen proportion of terminal products and bring users a more ultimate visual experience.In addition, the development and improvement of fingerprint under (in) LCD screen is inseparable from the dimensions of high brightness, high fingerprint recognition rate and improvement of unlocking experience. High brightness requires the brightness of the module to be more than 450 nits. To ensure that more image details are displayed, it can effectively solve the problem of serious brightness loss and bring a smooth viewing and game experience; The ultra-high fingerprint recognition rate refers to the FRR of 3%, which can reach the OLED level; in terms of unlocking experience, the use of unlocking or consumption functions is more intuitive, avoiding accidental touch, simplifying the buttons of mobile phone accessories and improving the overall beauty.It is understood that in the process of tackling the key problems of LCD off screen fingerprint technology, TCL Huaxing has solved the problems such as the development of Blu films, the improvement of TPM brightness and the improvement of infrared sensor recognition accuracy through continuous transformation and attempt of LCD backlight. Finally, TCL Huaxing has launched the LCD panel off screen fingerprint that can clearly see the fingerprint image, and realized the rapid identification function of LCD off screen fingerprint.Optimize cost and find the way of differentiated competitionThe advantage of fingerprint in LCD screen is that it can do large-area and multi fingerprint identification, and can improve the diversified space of human-computer interaction experience of intelligent terminal. For example, it can deeply encrypt app, ensure wealth security and improve vehicle driving experience; it can also provide higher-level guarantee for the information security of smart factory, smart city, smart home, smart transportation and intelligent medical treatment.According to Wu Zhen, in the future, the fingerprint on the LCD screen can encrypt any app. When users click the app icon, they need to complete fingerprint verification before they can further open and run the app. Compared with the encryption method that the existing mobile phone app needs to press the finger at the specified position for fingerprint verification, it is more convenient. The fingerprint on the LCD screen can even realize that when using a joint account on the ATM, two people need to use it at the same time The operation function of transfer can only be realized by inputting fingerprint.Since the release of full screen optical fingerprint identification LCD screen by Youda optoelectronics, Tianma's latest LCD multi touch in screen fingerprint scheme has met the conditions for mass production, and is sending samples to terminals of world-famous brands. The off screen (in) fingerprint scheme has been launched for a long time, but it has not been commercialized on a large scale. What step has the overall off screen fingerprint taken in the process of mass production application?Liu Yushi, senior analyst of cinno research, said in an interview that the under screen (inner) fingerprint of LCD has been opened up technically. Compared with the rigid OLED with optical under screen fingerprint, it has no advantage in mass production cost, so there is little practical application at present. At present, the under screen (inner) fingerprint of LCD is actively optimizing the cost and looking for a way to compete with the off screen fingerprint of OLED.Xu Jingjing, senior analyst of semiconductor device research at sigaintell, said in an interview with China Electronics News that the fingerprint scheme under the LCD screen (inside) is still in the research and development stage. From the perspective of application field, compared with mobile phone terminals, it is expected to be promoted in the vehicle display and door lock Market in the future, and mass production is expected to be realized in the second half of 2021.One of the evolution trends of touch display is to help the touch display module continuously add value by adding more functions from the device structure level. Although the latest LCD on-screen fingerprint solution still has some details to be optimized, the release of this technology has revived the confidence of practitioners in LCD fingerprint solution.

Payment app fingerprint security authentication, joint account withdrawal encryption fingerprint authentication... Many fingerprint identification behaviors are expected to be realized in a way of higher security and convenience through under LCD screen (internal) fingerprint identification technology.Due to the opaque characteristics of LCD screen, it is difficult to realize this technology. Nevertheless, many panel and mobile phone manufacturers have challenged LCD off screen fingerprint technology, which is evolving towards high integration, full screen fingerprint multipoint identification and high screen share.Evolution from "off screen" to "on screen"At present, the off-screen fingerprint identification technology applied to OLED mobile phones has been very mature. Due to the high cost, the selling price of mobile phones is generally high. Although the cost of LCD screen is low, the LCD screen itself cannot transmit light, so it is difficult to realize the fingerprint technology under the LCD screen. Nevertheless, in recent years, many panel and mobile phone manufacturers have challenged the fingerprint technology under the LCD screen and achieved certain results.In May 2019, AU Optronics displayed a full screen optical fingerprint identification LCD screen.In June 2019, BOE revealed that the optical fingerprint sensing technology under LCD screen has been successfully developed. In August 2019, Huawei glory demonstrated the LCD mobile phone prototype equipped with off-screen fingerprint unlocking. It is reported that this prototype is the result of joint development between glory and BOE.In March 2020, Lu Weibing, vice president of Xiaomi group and general manager of Hongmi brand, announced that Hongmi team had overcome the problem of screen fingerprint, realized screen fingerprint on LCD screen and had mass production.In June 2020, TCL Huaxing announced that it had developed fixed single point on-screen fingerprint technology. It is expected to launch full screen single point on-screen fingerprint technology this year and Full Screen multi-point on-screen fingerprint technology in 2021.In July 2020, the world's first LCD on-screen multi-point fingerprint solution (Ted finger print) developed by Tianma was officially released. The scheme embeds the fingerprint image collector in the TFT display substrate, realizing the integration of touch, display and fingerprint identification.What is the evolution process from "off screen" to "on screen"?It is understood that the development of off screen fingerprint is mainly divided into off screen fingerprint (fixed single point), on-screen fingerprint (full screen single point), on-screen fingerprint (Full Screen multi-point Ted embedded), etc. Off screen fingerprint identification includes capacitive, optical and ultrasonic types. However, due to technology and cost, most of the products equipped with this technology can only realize single point fingerprint identification in a fixed area. Now, the latest R & D achievement - on-screen multi-point fingerprint solution adopts the optical fingerprint identification mode, integrates the fingerprint image collector into the display screen, and can realize "Full Screen multi-point" fingerprint identification on the full screen, which has a larger screen identification area than off screen fingerprint products.Integration and multipoint recognition become the direction of attack"The future development direction of on-screen multi-point fingerprint solution must be high integration, full screen fingerprint multi-point identification and high screen proportion." Wu Zhen, director of marketing department of Tianma Microelectronics Co., Ltd., said in an interview with China Electronics News.Specifically, the first is high integration. It is mainly to realize the three in one of touch, display and fingerprint identification. It is necessary to break through the limitation that the optical fingerprint in the LCD screen is difficult to match the thickness of the normal cover plate, so as to have more market competitiveness and mass production; At the same time, because the optical path modulation unit is integrated in the display screen, the thickness of the display screen is reduced by more than 50% compared with the external collimating optical path design scheme, making the design of terminal products lighter and thinner. The second is full screen fingerprint multipoint identification. To support full Screen multi-point fingerprint identification in any display area, it can be applied to full screen blind unlocking, APP encryption unlocking and user-defined fingerprint control to achieve high security and high privacy. The third is the proportion of high screen. The fingerprint identification function is built into the display screen to effectively improve the screen proportion of terminal products and bring users a more ultimate visual experience.In addition, the development and improvement of fingerprint under (in) LCD screen is inseparable from the dimensions of high brightness, high fingerprint recognition rate and improvement of unlocking experience.
