  • Can I Shut Off My Laptop's Keyboard Without Turning Off My Computer?

    Use an external keyboard. It wo not be warm, so the cat is not as likely to sit on it. If you leave for a longer time, you can simply unplug it.

    Then cover laptop keyboard with something, as in @Alexandre Aubrey's answer. An additional benefit - indeed, the reason I do it even though I do not currently have a cat - is that it's a lot easier to work with a full-sized keyboard than a laptop one. And then you can plug a 21" or so display into the laptop's external video port

  • How Can I Use My Laptop As a Monitor for a Diffrent Computer?

    Unfortunately, many people wish they could use their old laptop LCD screens as an additional monitor, but it is not an easy thing to do, nor cheap. There is no adapter to fit the LCD connector in the laptop, and there is no way to plug the laptop LCD into any external source to receive video signals. Laptop LCD's are designed to work with the laptop's system board, and most of the video processing is done on the system board and then transferred to the LCD, unlike standard external monitors that have some electronics built-in to them to process the data signals.

    Laptop LCD's are usually somewhat proprietary in nature to work directly with the laptop it's in. It is possible to do what you wish, but it takes a lot of work and a degree in electronics to create a new interface to convert the standard video signal data into what the LCD can use. Basically, it's not worth it, unless you have a lot of time on your hands to do all the research necessary and electronics know-how to build the interface.

    There are a lot of wires that you would have to figure out as to what they are for, and how to adapt the signals to them. Sorry. Best of luck.

  • How Do I Set an External Monitor As My Primary When Connected to a Laptop?

    What type of laptop? Do you want to still run extended desktop, but with the laptop screen as the secondary, or do you just want to display on the monitor, and turn off laptop lcd? Need more information from you.

    To display on external monitor, most laptops allow you to choose that by cycling through your output mode. this is done normally by hitting your Fn key + F4 or F5. your laptop might be different, but F4/F5 is a safe bet.

    if you hold down Fn without releasing it, you should see your options for type of output. choose the one that is just an external monitor. If you are trying to display with primary screen on external monitor and extended desktop as laptop lcd, then you need to use the drivers/software installed with your graphics card.

    Normally you can access that by double clicking one of the two screens displayed in your properties tab, and clicking the corresponding tab. the software for the graphics card will pop up and allow you to configure however you want. this is a generic answer, but will ALWAYS work.

    If I knew your laptop and graphics card, I would be more helpful :| Good luck, post back if no luck.

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

Step 1: pull out the screwFirst turn the laptop over, and then remove the battery and the side of the laptop screen (remember to also open the screws hidden under the battery)Then, you will remove the keyboard screw that is usually located in the middle of the laptop (usually displays a keypad image) close to it to make your work easier)The last thing we have to do is disconnect the wire of the wireless antenna.On the HP dv9000 series, the wireless network card and memory are kept on the same plate, which gives us more space and makes us very easy.Find out which board hides your wireless card (it's harmless to open it all and view the contents below them in any way, because it's a learning experience)Once you find the network card and antenna wire with black, it winds out. Please note which wires go to which side of the card (I'm not sure of the importance of reconnecting them correctly, because they are only cut wires, and they won't close any circuits, but plug them back and attach things in the right way for the first time, ha ha)OK, now you can go to the top of the laptop.Step 2: remove the speaker frame and the annoying plastic cutting step.OK, so with the computer turned off and the battery removed from the device, press and hold the power button for 20 to 30 seconds to eliminate the remaining power. Capacitor, and then use a flat screwdriver to remove the speaker bezel from the device.Take your time, you won't break any plastic clips. We really want this unit to return together when it is finished.Step 3: screen screws and wiresOnce you remove the speaker bezel, you will see a (in my case) total of 6 wires protruding from the bottom of the screen into the laptop.From left to rightVideo cable, (cable for controlling all aspects of color and brightness such as LCD, backlight, etc.)The next step will be two thin lines that control the webcam on this displayOn the right side of the screen, you already have a wireless antenna cable and a webcam controller cable, and your replacement screen should already contain all of these.So just disconnect the laptop cable and connect it to the screen.If you don't care about these wires on the new screen, the screen may be wrong or the model may be small.You can consider taking the laptop screen apart and placing it horizontally (unfortunately, this may be troublesome, but it must be feasible).But go back to it, continue and pull out 2-3 or connect the 4 screws to the hinge of the laptop screen so that it can be gently lifted from the laptop.Now move the monitor away (but still tied to the laptop through the antenna cable)We can remove the keyboard, at the top of the keyboard, you will notice that the screws on the top of the 3 to 5 keyboards pull them forward and keep them apart(they will be different colors, so it's hard to keep them apart, but if you separate the screws in some way, it will make things easier), then gently lift the keyboard and pull it up (towards the screen), then tilt the keyboard so that you can see below it, and disconnect the cable connecting the keyboard to the laptop.Do not use this cable roughly. If you disconnect the keyboard cable when trying to fix the laptop screen, it will only cause problems and more money You may feel depressed in the whole room, = O ha ha, I don't want that.Step 4: serpentine antennaAfter unplugging the keyboard, the first thing to pay attention to is the of the wireless antenna(the only reason is to go so deep), so move on, release the wires from their small tracks and clips, and gently bend the end of the antenna into a line so that they can connect to the wireless network card at the bottom of the laptopRemember, if your wireless card has any unexpected twist or hook, how it will wind through, because you will need to reinsert the new antenna cable in one second.Step 5: throw it back.Once you release them, please continue and move your screen. It is broken and far away, but don't discard it in the future. The components on it may still be useful.Then grab your new monitor and start bending the wireless antenna lead back and locking it in place.Put the keyboard back in place and don't forget to reconnect the wires under the keyboard.Screw it back in place.(this is where we started to calculate the screws. We don't want to leave any screws. I hope you can remember their whereabouts well)Reconnect the video, microphone and camera wires to the laptop, and then screw the hinge of the laptop back to the laptop.Grasp the bezel of the laptop, fix it back in place, and then close the laptop,Turn it over and start replacing all the screws. Is there any left? Congratulations on winning!Slide the battery back into place (if not, connect the wireless antenna cable, just press it back into the slot). That's all. It's done. Open the suction cup again to see if you were cheated and bought another broken screen, or if you forgot to connect the wire correctly = P ha haIf it works properly, it means that you have successfully patted your back and waited for something. Otherwise, please break it so that you can regain new confidence and repair her = D

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 Display_ Application Method of LED Display Screen
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.

What Aspects Should Be Considered When Selecting LED Display Screen
What Aspects Should Be Considered When Selecting LED Display Screen
Indoor LED screen is favored by advertisers in large hotels and supermarkets because of its good display effect and visual feeling. So what should we pay attention to in the selection of LED display in hotel banquet hall?Generally, in the indoor environment, the screen area will exceed 3 m2. Therefore, in this case, there are three options: ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display.The advantages of ordinary rear projection display screen are small pixels and high definition. The disadvantages are low brightness, small viewing angle and short lens lamp life (only a few thousand hours). DLP has the advantages of small pixel points and high definition. The disadvantage is that it has seam. At present, the minimum seam can reach 1mm. Rear projection and plasma display screens are suitable for close viewing. For indoor LED display, the advantages are high brightness and no seam, while the disadvantages are coarse pixel particles and low definition. At present, the economic model of commercialized indoor full-color LED screen is p5p6, and other models include p3p4p7.62p8. LED display screen is suitable for indoor places with long viewing distance.When selecting LED display in banquet hall, the following aspects can be considered:1 die. Like the outdoor full-color LED screen, it is generally recommended that the LED of the indoor full-color display screen adopt the LED encapsulated by Maipu brilliance, and the tube cores of Japan Riya and Cree of the United States are recommended for high-end products.2. Packaging form. The 3528211010 surface mount package has the advantages of large viewing angle, good luminous consistency and easy automatic welding processing. It is the mainstream product of full-color screen.3 density. Due to the large heating capacity of indoor full-color LED chip and high density of control circuit, the point density of commercial full-color screen can not be very high. The screen models in lianchengfa room include p1.6p22.5p3p4p5, P6, p7.62, P8, etc.4. Driving mode. The driving mode of Maipu Guangcai indoor full-color LED screen is constant current driving and adopts dynamic scanning mode (mainly 1 / 4, 1 / 81 / 16 and other scanning modes).5 refresh rate. Improve the refresh rate, and there is no flicker and tailing when shooting with the camera.Other considerations include the scale and brand, price, purpose, installation location and environment of LED display manufacturers. The above are some suggestions on the selection of LED display in hotel banquet hall.fqj
Application and Technical Index of LED Full Color Display Screen
Application and Technical Index of LED Full Color Display Screen
Since this year, the market demand for LED full-color large screen has shown a rapid upward trend. Just after the Spring Festival, large projects began bidding. In April and may, despite the impact of SARS, it only delayed the implementation plan, not cancelled the project. After SARS, many projects have been stepped up. The contract amount of major LED large screen manufacturers increased by 20% compared with the same period last year, and some even almost doubled compared with last year. There are many new companies entering the field of full-color large screen, and their achievements are also excellent. Compared with previous years, the market sprouted early this year, with many large projects, and more than a dozen projects with more than 10 million yuan have been implemented. In the third quarter, many major projects entered the bidding stage. Another feature is the significant increase in projects invested by enterprises, including applications in commercial advertising. It can be said that led large screen, as a commercial advertising media, has been favored by the advertising industry again after nearly ten years of silence. At the same time, the export situation of full-color screens is also encouraging. In early September, the annual optical Expo was held in Shenzhen. This exhibition is a big exhibition of LED industry in the past year. LED large screen, LED lighting, LED traffic lights, LED production equipment, testing equipment and other dazzling, indicating that the new climax of China's LED industry has come. The author believes that this exhibition is a sign that China's LED industry has reached a turning point of localization. Internationally renowned LED light-emitting tube manufacturers and screen manufacturers have also begun to transfer to mainland China on a large scale. Mainland China will become the manufacturer of LED and its productsManufacturing center. Broad market, good investment environment and low labor cost make China gradually become the manufacturing center of the world's electronic industry. Just like computers, mobile phones, televisions and other electronic products, China is also the manufacturing center of LED large screen industry.As a scientific and technological worker who has been engaged in the research and development of LED large screen for a long time, the author has always paid attention to the development of LED large screen in China and the new achievements of international large screen display industry. Three years ago, in the article on the development of LED large screen, the author talked about several application fields and characteristics of LED large screen in China, and proposed that full-color large screen is mainly an image project in China. It should be said that this general pattern has not changed, but the increasing demand for commercial advertising is also a very important development trend. It can be said that China's LED full-color large screen industry is ushering in a new climax. Seriously studying the new situation of market development and technological progress, taking correct countermeasures, seizing opportunities, rapid improvement and sustainable development should be worthy of study by peers. Here, I venture to raise questions about technical indicators and hope that peers and experts will correct me.Image engineering: Aiming at the international first-class level. Image engineering means that the main purpose of building a large screen is to add style to the city or a major event. It does not directly create economic benefits, but it can enhance the city's popularity, shape the city's image, improve the investment environment and create a business atmosphere, which is conducive to economic development and good social benefits, so as to indirectly create economic benefits. Image engineering is mainly government investment, focusing on social benefits, rather than or mainly obtaining economic benefits through commercial operation. In recent years, the large LED screen of large squares in urban central areas or citizen leisure squares built in many parts of the country is a typical image project. A large number of LED displays in stadiums and gymnasiums are necessary supporting facilities for modern stadiums and gymnasiums, which also belong to this category.Since it is an image project, it is bound to pursue the perfect performance and effect as much as possible, especially high-quality video images. Generally speaking, it is to make a giant color TV, which has been worked hard by many domestic manufacturers for a long time, and has made considerable progress, but it is still far from our ideal goal, and there is still a big gap compared with foreign full-color large screens.At the beginning of this year, the commercial street of Hunan Road in Nanjing invested heavily in the construction of a full-color large screen with an area of 114 square meters. The screen was built by UNITEK company in the UK and has been running for more than half a year. From the effect, it can be called the best large screen in China. The author participated in the formulation of the technical indicators of the screen and the final acceptance test, and felt that many aspects were worthy of learning and imitation by domestic peers.As a large full-color screen, its key technical indicators include: high enough brightness, viewing distance and viewing angle; Good color reduction; Sufficiently high grayscale capability; High enough scan refresh rate. High enough video signal processing capability, especially good consistency, structure and technology. The technical indicators set by Hunan Road Daping during bidding are:The white balance brightness is greater than 5000 CD / m2;White balance color temperature 6500k;The number of video processing bits is greater than 10bit;The gray level of each primary color is greater than 10bit, which can display 1.07 billion colors;Refresh frequency is greater than 400Hz;The display screen has no perceptible color difference, and the color difference of each primary color of the full screen is less than 4nm;There is no perceptible brightness difference on the display screen, and the brightness difference of adjacent pixels is less than 5%. There is no perceptible mosaic when displaying monochrome gray images of red, green and blue;MTBF is greater than 5000 hours and MTTR is less than 30 minutes;Objectively speaking, not only at that time, but also today, the products of domestic manufacturers have not been fully achieved. In many cases, due to the improvement of the level of LED, the brightness of the normally designed large screen is no longer a problem and can meet the requirements. However, brightness is only an important indicator, not all. Now we generally feel that the large screen brightness of domestic manufacturers is more than enough and the softness is insufficient. The overall effect is not as good as that of foreign well-known manufacturers. The reason is that there are more technical problems that have not been solved. The author believes that from a technical point of view, it is necessary to make efforts in the following aspects.(1) Color matching and blendingThe large screen is composed of a large number of light-emitting diodes. The photoelectric parameters of the light-emitting diodes must be designed, calculated and tested in order to achieve a good white balance. Simple estimation and judgment with the naked eye can not have good results. This involves the selection and driving design of LED, which not only affects the photoelectric performance of the screen, but also affects the reliability. Especially in the design of indoor full-color screen, thermal design should be paid enough attention, otherwise the effect and reliability will be a problem.
