Hello, will using LCD for a long time affect the notebook screen? When using the LCD screen, pay special attention to its working time. When it works continuously at full load for more than 96 hours, it will age rapidly and even burn out in serious cases, resulting in huge economic losses to users. This is because the pixel points of the LCD screen are composed of liquid crystals. Working for a long time, it is easy to overheat some pixel dots. Once the limit is exceeded, it will cause permanent damage. This forms what is often called a "bad spot" (some media call it a "black spot"). Therefore, if the user has to work for a long time, the screen must be intermittently rested, and the same content cannot be displayed for a long time. When the screen is waiting to work, it is necessary to reduce the brightness. Using screen saver is a good habit. It can not only delay the aging of LCD screen and prolong its service life, but also avoid hardware damage. 　 If there is something wrong with my screen, can I take it apart? For the LCD screen, because its structure is very delicate, no matter what problem occurs to the user's screen, do not disassemble the LCD screen by yourself. If you suspect that your LCD screen is not working properly, you should ask the manufacturer to send professional eyes to help solve the problem. The transformer in the LCD background lighting assembly may still carry 1000V high voltage (although it is micro current) after shutdown for a certain time. If non professionals do not handle it well, it may cause new faults of the assembly, and in serious cases, it may also cause the screen to permanently fail to work - this is an unwise move to lose money for small things. 　 Hello, how can I prevent the laptop screen from aging? The lighting lamp in the LCD screen is the only natural consumption part. After a long time of use, it will age, resulting in the darkening of the screen and the decrease of brightness. If the screen darkens due to aging, you only need to replace the lighting lamp to bring the screen back to life and return to youth. Of course, the most important thing is to pay attention to maintenance at ordinary times. Prevention lies in the future. Based on the author's years of experience in screen maintenance, users can pay attention to some problems: for example, the brightness cannot be adjusted too high, and long-term high load work will accelerate the aging of the screen 　 Excuse me, do different flashing modes of LCD screen have different meanings? Due to the influence of the analog signal output interface, for example, the clock and phase of the pixel are not synchronized with the analog signal output, which will lead to flicker. This phenomenon is usually called pixel jitter. It is an occasional flicker phenomenon, which is inevitable in the process of analog / digital conversion. In order to solve this kind of problem, there are two methods. It can be "automatically adjusted". There is a "automatic setting" function on the LCD screen, which is used to adjust the LCD screen to the best state after analyzing the input signal. It can also be "manually adjusted", which can be adjusted by two functions: phase and clockHello, the weather is very bad recently. It's wet all around. Does it have any impact on the laptop screen? Dampness is the taboo of LCD screen. When using LCD screen, it must be placed in a ventilated and dry environment to avoid the invasion of water vapor. This is because the internal design of LCD screen is very precise. Once there is short circuit caused by oxidation and corrosion due to humidity, it will bring huge economic losses to users. If you accidentally wet the screen, don't panic and turn off the power first. If there is only moisture on the screen surface, wipe it gently with a soft cloth, and then turn on the power to work. If the moisture has entered the LCD screen, you must put the LCD in a well ventilated or warm place to let its moisture evaporate. If the situation is very serious, users should ask professionals to help solve it. Remember, first of all, turn off the power supply and do not let the LCD power on when the moisture is not removed, otherwise it will easily lead to the corrosion of the LCD electrode, and the best technicians will have no way to recover.

The cost to repair your Itel Vision 1 screen totally depends on which method you choose to fix it up. Few of the methods are like getting it fixed from authorized Itel service center or getting it fixed by a local repair shop in your area or to do it yourself. * The 1st option is to go to authorized Itel service center. They will charge a hefty amount on the same, but this will ensure 100% genuine replacement screen with warranty. Means this is the only method to ensure that you will get 100% genuine original screen and will get some limited time warranty on the part. * The 2nd option is to go to some local mobile repair shop in your area, where you can get your Itel Vision 1 repaired for a better price deal but this wo not ensure good quality part and an unreliable warranty. Just make sure that you do not get fooled by a shop who claims to have a original screen for a higher price. Do you really think he can have tie ups with Itel and get original genuine parts from them? The only way these shops can have a original screen is if they took out the screen from some other phone. Do It Yourself * The 3rd and the best option is to get a high quality replacement LCD Screen with Touch Digitizer for your Itel Vision 1 from a reliable online store (like maxbhi.com) and get it fitted from the local repair shop for just 200-300 Rs. This way you will get a good quality display screen with good prices and a reliable warranty. You can even try to do this yourself with the help of youtube videos and phone opening toolkit for Itel Vision 1. As per our research, Itel Vision 1 screen replacement should cost something around 3400 Rupees in India.Given current technology, could TV display screens double as video camera sensors?Given enough time, a very low resolution image could be recovered by changing the displayed image such that the liquid crystal layer allows light in through only a single pixel (or a small group of pixels). This would correspond to a black screen with a small white spot. By moving this white spot around the black screen and measuring the voltage at the backlight LEDs, some amount of spacial detail could be recovered (depending on the physical dimensions of the screen and the depth of the liquid crystal layer). The size and thickness of the spot will cause light rays to be rejected by angle based on the spot position.The minimum transmission area will be limited by the total amount of light transmitted by the black pixels, so your resolution will effectively be limited by the screen's contrast ratio as the white spot must be large enough to transmit more light than the black pixels over most of the screen.This would only be suitable for taking still images due to the time required to capture one frame, but the necessary mask frames could be hidden between frames during the display of a normal video on the screen.Can camerasdisplay screens with window/mirror-like optical behaviour exist?Transmitting each individual photon is infeasible, given the amount of computation that would be required, but technology for capturing some information about incoming light direction already exists and is used in the Lytro "light field" camera.The corresponding light field display does not exist, as far as I am aware. The Lytro system uses a conventional display with postprocessing that lets you adjust focal point, depth of field, etc. after the photo has been taken.what is the best brand and type of case for the iPhone 4s?pass with an otterbox or if you want display screen risk-free practices for the front get a pockets case for the iPhone you open and this is like an iPhone with a pockets very on hand. you will get them of eBay it is what I didSince the last Microsoft update to Windows 10, my display screens keep switching to a darkened version.

(source: Keke house)Whether it is the functional computer era more than ten years ago, the current smartphone era, or the 5g era that is about to enter, the security of devices has always been a hot topic. The iPhone x launched by Apple two years ago won the hearts of many fruit fans with its unique ID design. It is from this generation of iPhone that the home key used for many years disappeared. At the same time, fingerprint identification is also a stranger to Apple's mobile phone, and "face ID" has replaced it and become the symbol of the new iPhone.Compared with apple, some Android phones have found the best of both worlds in recent years. Among them, Xiaomi digital series and Huawei mate series are not only equipped with 3D face recognition technology equivalent to the security of face ID, but also place the continued fingerprint recognition function at the bottom of the screen. BOE's breakthrough in LCD screen fingerprint technology makes screen fingerprint identification no longer the "patent" of OLED.Although the face ID unlocking method has higher security, through the survey of some users, more than 65% of users think that fingerprint unlocking is more attractive to them, because fingerprint unlocking is more convenient than face unlocking. However, more than 90% of users want the mobile phone to support both face and fingerprint unlocking methods. The reason is like what toy Dragon said, "I can't use it, but you can't do without it".But the new iPhone released by apple in the past two years has always adhered to face ID, just like a boyfriend who has entered the sage mode, without mentioning fingerprint identification. Recently, it was reported that apple is studying a full screen fingerprint recognition scheme. If this technology is mature, fingerprint recognition will return to the iPhone.

key word:Corning, touch screen, notebookThe new protective glass helps to prevent damage to the touch screen; Corning gorilla glass enters new marketsCorning gorilla glass NBT, the latest protective glass launched by Corning today, aims to protect the touch screen laptop display from scratches and other damages caused by daily use.Gorilla NBT glass is a unique screen protection solution launched by Corning for touch screen laptops. Touch has become the main way of interaction between users and devices, and with the increase of touch interaction, the potential risk of glass scratch is also increasing. When these equipment are in intensive use every day, scratches will lead to the breakage of protective glass. Corning gorilla NBT glass has stronger scratch resistance. In case of scratch, the scratch visibility is smaller and the residual strength is higher, which can prevent the damage of notebook computer display when using sodium calcium glass with poor performance.Consumers pursue thinner, smoother and lighter personal computers with touch function. The market research conducted by market research institutions on the next wave of touch technology shows that in the next few years, in terms of protecting the glass market, laptops with touch function may reach the market share of smart phones. Corning gorilla NBT glass brings the world's leading protective glass solution with low cost, scratch and damage resistance expected by consumers to this new mobile device market."As the preferred protective glass for global equipment manufacturers, Corning gorilla glass has now entered the emerging touch screen notebook computer market with its special performance," said James R. Steiner, senior vice president and general manager of Corning special materials department. "As the demand for touch screen laptops continues to grow, we believe Corning gorilla NBT glass can challenge the current performance of soda lime glass, and its scratch resistance is 8-10 times that of soda lime glass. In fact, customers can now get the best protection glass solution at only 1% to 2% of the retail price of a laptop, which comes from gorilla Solution. In short, we believe that if you don't use gorilla glass on your device, it's not good enough. "Similar to handheld devices or tablet devices, consumers' physical contact with touch screen laptops includes tapping, tapping, grasping and cleaning. These interactions with laptop devices every day may cause scratches on the protective glass and affect the user experience. Corning consumer survey shows that the complaint rate of scratched laptop screens is more than four times higher than that of other mobile devices. Changing the screen can be very expensive, sometimes as much as half the price of the entire laptop, and users have to wait a few days."As a leader in touch computers, Dell is always looking for the best materials to ensure that our laptop screens can resist collision and scratch," said Sam Burd, vice president of Dell PC products group. "We used Corning gorilla NBT glass in the new client device to be launched this fall, which further strengthened the reliability and durability of our products to maintain the leading position in the industry."Corning gorilla NBT glass is now available and is expected to be applied to several notebook products of several world leading computer brands later this year.For more information about Corning gorilla NBT glass, please visit.

QFN package (quad flat no leads) - QFN is the name specified by Japan Electronic Machinery Industry Association (JEDEC).Four side pinless flat package, one of the surface mount packages, is a new surface mount chip packaging technology with pad at the bottom, small size, small volume and plastic as sealing material. Because QFN package does not have gull wing lead like traditional SOIC package, and the conductive path between internal pin and pad is short, self inductance? S number and package body? How long does it last? Therefore, it can provide excellent electrical performance, and because there is no gull wing lead, it can reduce the so-called antenna effect and reduce the overall electromagnetic interference (EMC / EMI). In addition, it also provides excellent heat dissipation through the exposed lead frame pad, which has a direct heat dissipation channel to release the heat of the chip in the package. Usually, the heat dissipation pad is directly welded on the circuit board, and the heat dissipation via in the PCB helps to diffuse the power consumption of the multi harrier into the copper grounding plate, so as to absorb the heat of the multi harrier; It can also achieve better land sharing effect. At present, QFN package has been widely used in general mobile phones and laptops, but it is about to flourish in LED display.Comparison of heat dissipation, size and volume between QFN and SOPGenerally, the size of SOP used is 104 mm2 (8x13x1.9mm), while the relative size of QFN is only 16mm2 (4x4x0.9mm), which is only 6 7 times the size of SOP; It has greater flexibility in the design of some small spacing display screens.Thermal resistance Ja) the coefficient is SOP = 59 / W, QFN = 39 / W, that is, the temperature from the chip node to the surface at the power of one watt. The following is the calculation formula of thermal resistance commonly used in the industry:TJ= ja*PDTaTJ= jc*PDTc Ja= jc* caSymbols and units used in the formula TJ C: node (chip) temperature Tc C: actual temperature Ta C: ambient temperature PD W: power supply voltage JA ( C / W): heat transfer impedance from actual to external surface JC ( C / W): heat transfer impedance from node to actual Ca ( C / W): heat transfer impedance from actual to external surfaceIn other words, if the same return temperature and power consumption, the node temperature on the chip will be different due to different packages. For example: if the ambient temperature is 85 C and the power consumption of the chip is 0.5W, the temperatures of SOP and QFN are as follows:Design of lamp drive in oneDue to the two characteristics of small volume and good heat dissipation of QFN, in the past, the specifications below pitch 16mm of outdoor display screen will choose the design of lamp drive separation because of the limitation of PCB board size routing and heat dissipation; That is, the LED light board and the driver chip board are placed on two to three different PCB boards respectively, and then connected with each other through connectors and cables. Although this design can solve the heat dissipation problem, the inductive effect generated through the connectors and wires may greatly reduce the color resolution of the display screen, and the inductive effect will also increase the chance of electromagnetic interference. When using QFN design; Because of its small size and no heat dissipation problem, the chip can be placed in the gap of the LED lamp. Therefore, it does not need to use more PCB boards and transmission lines. It is simpler in design and its cost can be reduced. Similarly, if the QFN design is used for the indoor display screen, the heat dissipation problem can also be greatly improved.

As a high-tech product, LED display has attracted great attention. The intelligent full-color display, which is controlled by computer and integrates light and electricity, has been applied in a wide range of fields. The pixel points adopt LED light-emitting diodes, and many light-emitting diodes are arranged in a dot matrix to form an LED array and then an LED screen. Through different LED driving modes, images with different effects can be obtained. Therefore, the advantages and disadvantages of LED driver chip play an important role in the display quality of LED display screen. LED driver chips can be divided into general chips and special chips.General purpose chips are generally used for low-end products of LED display screens, such as indoor single and dual color screens. The most commonly used general chip is 74HC595, which has the functions of 8-bit latch, serial shift register and three state output. Each channel can output 35mA non constant current at most.Because LED is a current characteristic device, that is, on the premise of saturated conduction, its brightness changes with the change of current, not with the change of voltage at both ends. The biggest feature of the special chip is to provide constant current source output, ensure the stable driving of LED and eliminate the flicker of LED. With the characteristics of high output current and constant current, it is suitable for occasions requiring high current and high image quality, such as outdoor full-color screen, indoor full-color screen, etc.LED driver chip series products for LED display smt5026.smt5026 has built-in CMOS shift register and latch function, which can convert serial input data into parallel output data format.Part II: system architecture of LED display screen(1) Display unitThis is the main part of the LED display screen, which is composed of luminous materials and driving circuits. The indoor screen is the unit display board of various specifications, and the outdoor screen is the unit box.(2) Main controllerThe function is to buffer, transform and reorganize the input RGB digital video signal, and generate various control signals.(3) Switching power supplyThe purpose is to change 220V AC into various DC to supply various circuits.(4) Transmission cableThe display data and various control signals generated by the main controller are transmitted to the screen body by twisted pair cable.(5) Scan controllerThe function of the circuit board is to buffer data and generate various scanning signals and duty cycle gray control signals.(6) Special display card and multimedia card (video card)In addition to the basic functions of the computer display card, the LED full-color display card also outputs digital RGB signals, line, field, blanking and other signals to the main controller. In addition to the above functions, the multimedia card can also change the input analog video signal into digital RGB signal (i.e. video acquisition).(7) Other signal sources and their external devices
