What Is an OLED Display? This Article Teaches You to Understand the Difference Between LED Backlight

LED backlight refers to the use of LED (light emitting diode) as the backlight of LCD, while LED backlight display is only the backlight source of LCD, which is transferred from traditional CCFL cold light tube (similar to fluorescent lamp) to LED (light emitting diode). The imaging principle of liquid crystal can be simply understood as that when the external voltage is applied to deflect the liquid crystal molecules, it will block the transmittance of the light emitted by the backlight like a gate, and then project the light into the color filters of different colors to form an image.

The transition of backlight module from CCFL to LED can bring many benefits, which can make the brightness of the display screen more uniform, the product power consumption is lower, and the shape can be lighter and fashionable. However, w-led (white LED) backlight is widely used in the market. In fact, this backlight only replaces the luminous components, and the improvement of display effect is very weak or even not improved. Rgb-led (three color LED), which has significantly improved the display effect of LCD products, has significantly improved the display effect, but at the same time, the production cost is high, so it is applied to high-priced LCD TVs. At present, the LED display mentioned by businessmen refers to the display products with white LED backlight. The difference between it and ordinary LCD is the change of backlight.

LED display screen integrates microelectronics technology, computer technology and information processing. It has become the most advantageous public display media with its advantages of bright color, wide dynamic range, high brightness, long service life, stable and reliable operation. At present, LED display screen has been widely used in large squares, commercial advertisements, stadiums, information dissemination, news release, securities trading, etc, It can meet the needs of different environments.LED display is a display mode by controlling semiconductor light-emitting diodes. Its general appearance is composed of many usually red light-emitting diodes, which display characters by turning on and off the lights. A display screen used to display text, graphics, images, animation, market, video, video signals and other information.OLED display is considered as the emerging application technology of the next generation of flat panel display because of its excellent characteristics such as self illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panel, wide temperature range, simple structure and process.

OLED is the abbreviation of organic light emitting diode, which is translated as organic light emitting diode or organic light emitting display. In fact, this luminescence principle was discovered as early as 1936, but it was not until Kodak launched OLED double-layer device in 1987 that OLED attracted people's attention as a commercializable and excellent flat panel display technology. At present, more than 100 research units and enterprises around the world have invested in the R & D and production of OLEDs, including display giants in the current market, such as Samsung, LG, Philips, Sony and so on. On the whole, the industrialization of OLED has begun, in which monochrome, multicolor and color devices have reached the level of mass production, and large-size full-color devices are still in the research and development stage, but the production capacity is still low.

Many netizens are easy to associate OLED with the LED backlight hyped by current manufacturers. In fact, OLED and LED backlight are completely different display technologies. OLED emits light by driving the organic film itself through current. The light can be monochrome such as red, green, blue and white, and can also achieve full-color effect. Therefore, OLED is a new luminous principle different from CRT, led and liquid crystal technology.

The LED display screen is composed of LED dot matrix and ledpc panel. The text, picture, animation and video can be displayed by turning on and off the red, blue, white and green LED lights. The content can be changed at any time. All components are display devices with modular structure. The traditional LED display screen is usually composed of display module, control system and power supply system. The display module is composed of a dot matrix composed of LED lamps, which is responsible for luminous display; By controlling the lighting of the corresponding area, the control system can make the screen display text, pictures, videos and other contents. Monochrome and two-color screens are mainly used to play text. The full-color LED display can not only play text, pictures, animation, but also play video and other formats.

At present, it is widely used in every corner of the world because of its wide audience area, simple operation, long service life, energy conservation and environmental protection. In general, LED display, LED backlight and OLED are three completely different imaging technologies.

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.

How Does QFN Package Solve the Heat Dissipation Problem of LED Display Screen
How Does QFN Package Solve the Heat Dissipation Problem of LED Display Screen
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.

Analysis of System Composition and Architecture of LED Display Screen
Analysis of System Composition and Architecture of LED Display Screen
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

With the Rapid Development of Mobile Internet, the Production Qualification Rate of Display Screen I
XXX backlight panel manufacturing factoryWith the rapid development of mobile Internet, the software and hardware technology of smart phones have been rapidly improved. At the same time, the price is also developing in the direction of more and more civilians, which makes the development of smart phones in China more and more diversified and the scope of application more and more comprehensive, and plays an extremely important role in people's intelligent life.Mobile phone display screen is an important part of smart phone. The production qualification rate of display screen and the production quality of mobile phone play a very important role in the popularization of mobile phone. Unqualified mark line will lead to product display problems. The traditional mark detection is an artificial naked eye detection method. There is a phenomenon that the detection change range is too large due to the instability of the artificial naked eye, which leads to the problems of inaccurate detection and low efficiency.At present, many types of work requiring precise calculation have been replaced by automation equipment, and the visual inspection of backlight is no exception. Follow the Xiaobian:What problems can be solved?It mainly detects the mark line of the mobile phone backlight, including:Number of mark lines (excessive and missing);Mark line length, accuracy plus or minus 0.1mm;The distance from the mark line to the specified frame, with an accuracy of plus or minus 0.1mm;Camera assemblyDetection processTest effectTake two stations as an exampleTest conclusionFrom the early sample test results, the software can accurately detect the edge of each sample and the mark line on the product, and accurately calculate the length of each mark line, the distance between each mark line and the edge and the number of mark lines. The specific indicators are as follows:(1) Detection accuracy: 0.1mm (compared with the actual product, it is related to the marking and filling method, appearance and measurement benchmark, and there will be corresponding fluctuations)(2) Detection efficiency: it varies according to the number of mark lines, 20 for each piece, and the detection time is within 0.5s;(3) Product model: support multiple models of the same material, with the maximum size of 80 * 160mm.(4) Mark line color: white and black. The detection parameters need to be adjusted.

Laptop display screen won't light up?the only way that i comprehend to tell for specific if it is the backlight or inverter is to plug a regular solid backlight into the inverter. If it lights then it is the backlight, if no longer it is the inverter. The inverter is a miles less costly, ordinary restoration or it is going to be besides. The backlight section is way less costly yet is complicated (study high priced) to interchange except you pick to aim it your self. It frequently is not the two4. Why do we call a computer or TV display a "screen?I discovered a very helpful passage from the book, The Oxford Handbook of Management Information Systems: Critical Perspectives and New Directions(link takes you to the passage)The author notes that the word "screen" originates from the 14th century, andevolved from the Middle English word serene, from the Middle French escren, and from the Middle Dutch scherm. It is a word akin to the Old High German (eighth century) words skirm, which meant shield, and skrank, which meant a barrier of some kind. The word screen also suggests another interesting signification, further away from us in history. It is a word 'probably akin' (MW) to the Sanskrit (1000 BC)" words carman, which meant 'skin', and kn'z'nti, which signifies 'he injures' (MW). These are possible meanings from which the Middle Age words evolved. The Sanskrit clue suggests that the notions of protection, shield, barrier, separation arose, possibly within the older Proto-Indo-European language, as metaphors of the concept of skin-possibly that of human (or animal) skin.So there is a lot to do with protection and barrier which run through the evolution of the word. The author goes on to describe the chronological relations between the words:A barrier or a protection is something raised over and against another something. This 'other' something faces the barrier, as the wind faces the windscreen of a car, which means that the screen protects against something, to be excluded, that moves towards it. That which is moving towards the screen could have been understood as a projection (from the Latin word projectare, which meant 'to throw forward') over a surface-just like the arrows and bullets were projected over the shields, or like the heat is projected onto the fireplace screen. The screen protects and shelters (just as a skin. . . ) because it receives and holds the projection of that which is not to be received 'inside' the cover that the screen provides. But what happens when something stopped by the screen is allowed to pass through? The answer is that it was screened. This means that it was permitted to pass through that barrier, or that it simply passed through it. The screen as a barrier is now understood as a 'system for detecting [for example] disease, ability, attribute' (OPDT 1997: 681-2). This interpretation links, or so we hope, the three central themes of meaning attached to the word screen: hiding/protecting, projecting/showing, and testing/selecting (ibid.).The author goes on to argue that these three themes all have a central intent - a demand for our attention. They provide this table to help show this. P.270I think that should pretty much answer the question. The author has other interesting things to say on the word as well, and explains the phenomenology of the word and relates it to concepts like "the truth in seeing". Interesting stuff!

Aventk UV Color Changing Black Glue 1098 Can Effectively Solve the Reflection Problem of OLED Displa
Reflective problem of OLED display The core of OLED is a transparent organic semiconductor polymer, which can be made into a thin film and emit light by applying an electric field on both sides. Because the structure of OLED panel is very simple in theory, very thin products can be made. At present, the thickness of OLED display screen in mass production is only 0.95mm. Although OLED display is a self luminous product, after removing the backlight, there should be no problem of backlight leakage in theory. However, in terms of actual products, due to the existence of MF coating, there is still a problem of reflection around the edges of the display screen, as shown in the following figure:Therefore, how to solve the reflective problem of OLED display has become a concern of many manufacturers. In this regard, aventk has also studied and tested for many times, and finally determined that aventk 1098 series UV color changing black glue can solve this problem. Aventk UV color changing black glue 1098 can solve the problem. In solving the reflection problem of OLED display screen, most of them used UV black glue before. However, UV black glue needs to take into account UV light irradiation, so the blackness cannot be too deep, otherwise UV light cannot irradiate the cured glue. However, if UV glue black is not enough, it can not achieve good light blocking effect.To solve this problem, aventk 1098 series UV color changing black glue can be solved. Aventk UV color changing black glue contains aventk's exclusive NYX technology. NYX technology is aventk's unique UV light dyeing technology, which perfectly combines UV light with glue dyeing. It is a transparent color before UV curing and can well absorb UV light. After UV curing, it becomes black (or other colors). It not only meets the high efficiency of UV light curing, but also quickly completes the dyeing of glue. Put aventk UV color changing black glue is applied around the OLED display screen and between the screen and pol, which can greatly reduce the problem of reflection. fqj

The sensors will need to record at a very high data rate, on the order of petahertz. Every single pixel will be receiving all of the light that is in its field of view, and none of the light will be focused. Fortunately, light is not just photons, it's also electromagnetic waves. The sensors will behave like antennas, rather than eyes, passively collecting the radio waves at the wavelength of visible light.Radio signal sources can be tracked quite easily, by measuring the timing of a wave reaching multiple antennas. The same applies to all sorts of waves; an earthquake's epicenter is calculated by measuring the timing when the waves arrive at seismometers. We even have the same types of sensors built into our own human bodies. : Our ears can taking a wave and determine the direction that it came from, based on changes of intensity and timing. We have already proven the concept using vast antenna arrays to collect unfocused photons, to create a focused image. We imaged the supermassive black hole M87* using the Event Horizon Telescope.Of course, when astronomers use the term "photon" they do not just mean visible light; they mean any coherent electromagnetic wave. This image represents the peak of current engineering feasibility for synthetic aperture imagery. The EHT uses a Very Long Baseline Interferometry, which works in 450 GHz, using very narrowly calibrated equipment designed specifically to tease out the glow of the accretion disk at the wavelengths to detect event horizons around black holes. In order to get meaningful data, though, your sample rate needs to be at least twice the frequency of the signal rate, preferably more than 4 times the signal rate, or you start getting downsampling errors called aliasing. In order to record visible light, which has frequencies between 405 THz to 790 THz, you will need a sample rate that is at least 1.58 PHz.Due to limitations from the speed of light, and the time that it takes electrons to pass through silicon and copper in computers, this is just past the fastest speed that we can record data meaningfully.We would have to pass the data from several sensors in order to build up a meaningful synthetic aperture image from interferometry. We would need specialized recording technology that we just do not have yet.And, there's also the problem that LEDs are not designed to collect light, even though they are capable of doing it. .. just as sound coming out of a microphone would sound terrible, and sound recorded from speakers is also low quality. It would take several generations of iterating on the current science in order to use an LED-based computer monitor to record what is happening it a room, and it will always require specialized systems to just record the data in a meaningful way, much less process it into an image. It took several petabytes of data and 3 years of processing in order to build the EHT's image of M87*. It was faster to hand-carry the hard drives from the telescopes around the world to the datacenter, than it would have been to send the data over high speed internet links. It would take a lot of iterative work to miniaturize the chips necessary to do the calculations, but the technology just barely exists.Such a screen would be prohibitively expensive, as it's much easier to just put a lense in front of a cluster of photodiodes (i. e. , a webcam) and hide that in the corner of the screen, but those leave physical evidence... you can see the lense if you take the screen apart. It could be possible, with non-digital interferometry, to construct such an image of the room in real time. .. but that equipment barely fits in the basements of large telescope observatories, and requires cryogenic cooling. You would not be able to collect it clandestinely, and would be much cheaper (and higher quality) to use a webcam.

What are the components of LED displayLED display is a flat panel display, which is composed of small LED module panels. It is used to display text, image, video, video signal and other information. The components are as follows:1 LED unit board: it is one of the core components of LED display. The quality of the unit board directly affects the display effect of the display screen. The unit board is composed of LED module, driver chip and PCB circuit board. The LED module is actually composed of many LED light emitting points encapsulated in resin or plastic lattice.2 Connection: it can be divided into data line, transmission line and power line. The data cable is a flat cable used to connect the control card and the LED unit board. The transmission line is used to connect the control card and the computer. The power cord is used to connect the power supply, control card and LED unit board. The copper core diameter of the power cord connecting the unit board shall not be less than 1mm.3 Power supply: the power supply generally uses switching power supply, 220V input and 5V DC output. It should be pointed out that because the LED display screen belongs to precision electronic equipment, switching power supply should be used instead of transformer.4 Control card: we recommend using a low-cost strip screen control card, which can control a 1 / 16 scanned 256x16 point two-color screen and assemble the most cost-effective LED screen. The control card belongs to asynchronous card, that is, the card can save information without power off, and the information stored in it can be displayed without connecting to PC.Application method of LED display screenLED display screen can help a unit to show what they want to say and release some announcements and information, so as to facilitate visitors to understand some basic information of the unit.1.
