The LED soft screen is composed of LED dot matrix. Texts, pictures, animations and videos are displayed through the flashing of red, green and blue light bulbs. The contents can be replaced at any time. Each component is a modular display device. The clever structural design makes it possible to achieve horizontal and vertical bending deformation installation, even if it is a complex installation requirement, it can be perfectly realized; it is usually composed of a display module, a control system and a power supply system. Its characteristics are as follows: Can adapt to complex installation environment: It can be installed with horizontal and vertical bending deformation, even if the complex installation environment can present a perfect picture; Easy maintenance: Using the original LED embedded bar structure, only 3 nuts can be replaced to replace a single light bar, and the use of the site can achieve rapid maintenance; High protection level, no fear of bad rain weather: Tested by a third-party professional organization: M series soft screen protection grade up to IP65, no fear of harsh rain weather, can rest assured to use in outdoor environment; Light (12 kg/m2): Weight is only 12 kg/m2, one person can easily install and move products, saving you time and cost of product installation; Through: The pixel strip structure design, the product penetration rate of up to 60%, very low wind resistance, the highest level of resistance to 12 wind, you can rest assured that the use of the product in the windy weather; Thin: With a thickness of only 11mm, it occupies less space, saves you space on the stage and transportation space, and brings great convenience to your use and transportation.

Ordinary LED display features: 1. High brightness: The brightness of outdoor LED display is more than 8000mcd/m2, which is the only large display terminal that can be used outdoors in all weather conditions; the brightness of indoor LED display is greater than 2000md/m2; 2, long life: LED life of up to 100,000 hours (ten years) or more, this parameter generally refers to the design life, brightness is dark; 3. Large viewing angle: The indoor viewing angle can be greater than 160 degrees, and the outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED light emitting diode; 4, the led screen area can be large or small, as small as less than a square meter, as large as several hundred, thousands of square meters; 5, easy to interface with computers, support software rich; 6. Comparison of common large led display terminals. Through these characteristics analysis, we may conclude that LED soft screen screen has more advantages than ordinary LED screens: light, thin, transparent, easy to install and maintain, flexible, and more energy-saving. In the future, with the advancement of LED display technology, more, better and more energy-efficient LED displays will emerge.

The loss of control of the pixel of the full-color LED display is a relatively common problem. What is the cause of this phenomenon? How to solve it? The pixel point of the LED display is out of control, meaning that the smallest imaging unit (pixel) of the display is not working properly. The ratio of the number of uncontrolled pixels to the total number of pixels in the full screen is called the [full screen pixel runaway rate". There are two kinds of pixel out-of-control modes. One is the blind spot, that is, the blind spot. When it needs to be bright, it does not light, it is called the defect; the second is the constant bright spot. When it needs to be off, it is always lit. It is always bright. Generally, the common LED display pixels are composed of 2R1G1B (2 red lights, 1 green light and 1 blue light, the same reason below) and 1R1G1B, and the runaway is generally not the red, green, and the same pixel. The blue light is out of control at the same time, but as long as one of the lights is out of control, we think that this pixel is out of control. Therefore, it can be concluded that the main cause of the loss of control of the full-color LED display pixel is that the LED light is out of control. The main cause of LED lamp failure can be divided into two aspects: one is the poor quality of the LED itself; the other is the improper use of the method. The loss of control of the LED light is undetectable in the routine inspection test of the LED. In the harsh conditions of high temperature, low temperature, rapid temperature change, etc., due to the difference in thermal expansion coefficients of LED chips, epoxy resin, brackets, inner leads, solid crystal glue, PPA cups, etc., the internal stress is different. Electrostatic discharge causes the mechanism of LED runaway to be very complicated. Equipment, tools, utensils and human body may have static electricity and discharge it. This static electricity is as low as several hundred volts, high is tens of thousands of volts, and discharge time is in the nanosecond level. . If the blue-green tube is out of control, it is often the LED-PN junction that is broken down by electrostatic discharge. Due to the complicated production process of the LED display, the electrostatic discharge cannot be prevented. Therefore, the electrostatic protection must pass through the whole process of production. In different occasions, the actual requirements of the pixel out-of-control rate are different. The full-color LED display index is required to be controlled within one percent; the monochrome LED display indicator is required to be controlled within one tenth. At present, there is no good solution for full-color LED display pixels. It is recommended that the contact service provider return to the factory for repair. If the maintenance cost is too high, consider replacing the defective module unit board. At present, the domestic LED display will undergo aging test before leaving the factory. The LED lights of the out-of-control pixel will be repaired and replaced. The "full-screen pixel runaway rate" is controlled within 1/104, and the "regional pixel runaway rate" is controlled at 3/104. There is no problem within 104. Even some enterprise manufacturers' standards require that out-of-control pixels are not allowed before leaving the factory, but this will inevitably increase the manufacturer's manufacturing and maintenance costs and extend the shipping time. In different applications, the actual requirements of the pixel out-of-control rate can be quite different. Generally speaking, the LED display is used for video playback, and the index requirement control within 1/104 is acceptable and achievable; If used for simple character information distribution, it is reasonable for the indicator to require control within 12/104.

A pixel of led display is a unit used to calculate a digital image. Like a photo taken, a digital image also has a continuous tone of lightness. If the image is magnified several times, it will be found that these continuous colors are actually small squares with similar colors. The dots are composed of the smallest unit "pixels" that make up the image. This smallest graphic unit can display a single coloring point on the led screen. According to the color principle, it is known that red R, green G, and blue B are called three primary colors. These three colors can be combined to give any color from black to white. In the LED display classification, there are a monochrome display, a two-color led display, and a full-color led display. Monochrome is relatively simple, and only one of the three primary colors is required to achieve monochrome led display. In practical applications, there are more red LED lights. In this case, a red LED is a pixel. The two-color led display is similar to the monochrome display. You can achieve two colors by selecting any two of the three primary colors. In practical applications, choose red and green. When both red and green are on, yellow can be achieved. Therefore, the two-color display can realize three colors of red, green and yellow. Monochrome display LED illumination uses a solid semiconductor chip as a luminescent material. In the semiconductor, the carrier emits excess energy to cause photon emission, and directly emits red, yellow, blue, green, cyan, orange, purple, and white. Light. Full-color LED displays need to be able to express different colors from black to white because they have to display a wide variety of colors. Therefore, the full-color LED display requires three lights of red, green and blue to form a single pixel, in order to display a variety of colors. In the full-color LED display, it is divided into a real pixel display and a virtual pixel display. Because the display technology used is different, the way pixels are formed is different. The virtual pixel display adopts LED multiplexed virtual pixel technology, and adjacent LED light-emitting tubes can be combined to form one light-emitting tube through up, down, left and right four times; the real-pixel display screen adopts normal three primary colors to form one pixel technology. The points of the virtual pixels are scattered, and the points of the real pixels are condensed. The light-emitting point of the virtual pixel is between the tubes, and the light-emitting point of the real pixel is on the tube. Let's take a look at the LED display pixel technology: 1. Dynamic pixel technology: split a pixel into several independent LED units. Each of the LED units reproduces corresponding primary color information of a plurality of adjacent pixels in a time division multiplex manner. 2. Virtual pixel technology: In the display system, when the displayed information is scrolled in a certain direction in a certain direction, a series of movements between two adjacent pixels are generated by utilizing the characteristics of the human short-lived visual effect. Virtual pixels that do not physically exist, thereby adjusting each LED single tube to enhance the resolution of the full color LED display to achieve the best image effect, the theory is to improve the image resolution, generally 4 times. 3. Pixel sharing technology: A complete independent pixel of the display terminal is time-division multiplexed, and is cyclically refreshed by information of multiple adjacent pixels in the signal source. It is understood that a plurality of pixels in the signal source share a complete independent pixel of the display terminal in a time division multiplexing manner.

With the rapid development of modern technology, China's LED display industry continues to grow at a high speed, the scale of led display screen industry continues to expand, and technology continues to evolve. The market share of led display has continued to grow at an average annual growth rate of 40% since 1993. However, 2012 The sudden fire incident at the Yijun Hotel in Hong Kong on April 2 gave the whole LED display industry an alarm: while the industry is developing at a high speed, the LED display screen safety application technology field is still short-lived, and the standardization of LED products Standardization was once again on the agenda. In particular, the LED display screen fire safety application technology is more focused. The quality of led display screen fire prevention technology is mainly related to the fire curtain raw materials and box process. The fireproof raw materials mainly include four parts: the wire used in the display screen, the power supply, the external protective structure fireproof material and the plastic kit: First point: In most of led display applications, the larger the unit area of the display screen, the higher the power consumption, and the higher the power supply stability of the wire. Among the many wire products, the wire can meet the requirements of the national standard to ensure its safety and stability. There are three requirements: the wire core is a copper wire conductive carrier, the wire core cross-sectional area tolerance is within the standard range value, and the rubber core of the wrapped wire core is insulated. And the flame retardancy reaches the standard. Compared with the general copper clad aluminum wire core, the wire core cross-sectional area is small, and the insulation rubber grade is not enough, the electric current performance is more stable, and the short circuit condition is not easy to occur; Second point: UL-certified power supply products are also the best choice when selecting similar products. The effective conversion rate can ensure the safety and stability of the power supply load, and it can work normally even under the hot external environment. The third point: in the material of the external protective structure of the led display screen, the led display screen products with higher fireproof rating on the market mostly adopt fireproof aluminum-plastic board, which has excellent fire resistance, fire retardant and strong flame retardant. Aging performance is also very strong, melting point temperature 135 ° C, decomposition temperature ≥ 300 ° C, environmental performance, low smoke and halogen-free, in line with SGS, flame retardant B-S1, d0, t0, reference standard UL94, GB/8624-2006. The aluminum-plastic panel of the general outdoor led display screen product is aging faster with high temperature and rain and cold heat shock, so that in the relatively humid climate season, the rain dew easily penetrates into the screen body and causes short circuit of the electronic component to cause fire; The fourth point: an important part of the led display fireproof raw materials, that is, the plastic kit, the plastic kit is mainly used for the unit module mask bottom shell, the main raw material is the PC+ glass fiber material with flame retardant function, which not only has resistance The burning function can not be deformed at high and low temperatures and long-term use, and will not become brittle and cracked. At the same time, it can be combined with the glue with good sealing performance, which can effectively block the rainwater from the external environment from penetrating into the interior and causing short-circuit fire. . In addition to the internal raw materials will affect the fire prevention effect, the external configuration and design are also very important, but the external configuration mainly involves the heat dissipation in the fire prevention problem. In the display screen work, the exhaust fan and the air conditioner will be configured to cool and cool the inside of the screen body. It is recommended that every 8-10 square meters of 1P air conditioner ensure that the temperature inside the screen is kept at a normal temperature. If the air conditioner or exhaust fan is not in place, the heat treatment will be uneven, which may cause safety hazards in the screen due to temperature increase. At the same time, many LED companies simply test the spray waterproof test in the external environment when testing the protection level of the cabinet. The durability and strength of the waterproof effect are yet to be verified, so that after the display screen product has been used for a while, Water seepage occurs, which is an important reason why outdoor display screens are prone to fire or have a short service life. In response to thunderstorms, the screen device arrester is also an indispensable tool to avoid lightning strikes and burn out the internal components of the screen. It can directly direct lightning into the ground without affecting the screen. All of the above are internal reasons for the led display screen. Of course, we can't ignore the human factors caused by the post-maintenance process. For example, in the follow-up maintenance work, the operators did not follow the strict process flow (the module screws are not tightened, the wire rod If the polarity is reversed, and conductive objects are left behind after the operation, it is easy to cause a fire. The exact reason for the fire show in Hong Kong hotels remains to be investigated, but it is not possible to adopt a negative attitude towards the application of LED display products in Hong Kong. Although the entire led display industry standard has not yet been established, the industry has done a good job. There are still many LED display companies. These led display screen products that meet international certification standards are the best in the LED industry. We should be In line with these leading model companies, we will demand ourselves with high quality and strict specifications to guide the healthy development of the industry, thereby enhancing the international competitiveness of the entire industry and becoming international.

In view of people's demand for super strong visual impact and the actual demand for large-scale space applications, large led display screen has become an indisputable trend in the display field. Compared with the traditional LCD, plasma and DLP three large-screen splicing, LED display with automatic brightness adjustment function, can achieve the best playback in different brightness environments, to achieve the advantages of both indoor and outdoor applications. In addition, the led display also has the advantages of low cost, theoretically unlimited stitching, high brightness, low operating voltage, low power consumption, miniaturization, long life, impact resistance and stable performance. Based on its own unique advantages, LED displays are widely used in many fields including aerospace, aircraft, automotive, industrial applications, communications, and consumer products, covering various sectors of the national economy and thousands of households. At the BIRTV show that opened on the 23rd, as one of the popular display terminals, LED screens are also seen everywhere. In order to attract the attention of the audience, numerous manufacturers are making every effort to make the LED screen display a unique landscape on the exhibition. Manufacturers of various tricks, LED screen display features Outside the 9th pavilion, the media's ingenious "luxury beauty" effect has attracted many visitors' attention. The luxurious car with modern features is accompanied by vintage women with spears and shields. In the stadium, the smashing footage displayed video booth was full of action and attracted many viewers to stop and enjoy. High-brightness display, changing colors, gives a powerful visual impact. The changing natural landscape of multiple LED displays makes people's eyes brighten and they feel a lot closer to nature. In order to enhance the shock of the picture, LED screen on the ground showing a gorgeous picture, and the upright screen with each other, let the audience have a more three-dimensional visual experience. If you say this to the eyes of the audience, the quick approach is more practical. At the meeting, through its own launch of high-definition LED seamless big screen broadcast fuse, Avatar and other hot video, with "eyes" for "eye edge." China is currently the world's largest supplier of LED display products. The production technology of domestic LED displays is basically in sync with the world. From the technical point of view, the brightness of outdoor LED display is greater than 8000mcd/m2, which is the only large display terminal that can be used in outdoor weather. The brightness of indoor LED display is greater than 2000md/m2, which fully meets the needs of large space use. At the same time, theoretically speaking, LED screen life is as long as 100,000 hours (ten years). From the application level, the current application of LED screens is mainly advertising and information display. As a media advertising application, LED full-color screen is the user's first choice for visual impact, while display applications in financial venues such as transportation, highways, banks, and securities trading, single- and double-color led displays are more popular. According to relevant data, there are currently at least 2,000 domestic manufacturers that are known as LED screens. On the one hand, this is evidence that the LED screen market has been widely recognized as a highly promising market, proving the industry`s positive nature. On the other hand, we cannot ignore that the involvement of many manufacturers with varying levels of technology has led to uneven quality of products in the market. In addition, there is no strict standard system in the country, which seriously depletes industry standards and gives users practical applications. According to industry analysts, the establishment of industry standards for the local LED display industry is imminent. Without quality assurance, a large number of potential customers will be lost and the industry as a whole will fall into a quagmire and be unable to move forward. Due to the LED display advantages, it can be widely used in different scenarios. According to relevant personage's prediction, in the future with the new demand of various large-scale sports competitions and the vigorous promotion of the World Expo, the application market of LED display screens will be greatly expanded. And, given that the large-scale LED display screen that has been set up will experience a wave of replacement every 10 years, there will be a large burst of LED display screens in the future.

With the advent of the digital age, the emergence of digital media has dramatically changed the form of advertising and the carrier of communication. From the inkjet printing introduced in the 1990s to the large-size LED display screens today; from a single picture with poor visual performance to a dynamic performance with strong visual impact. Giant LED Screen is used in building curtain walls, municipal engineering and sports events in major cities, which undoubtedly become the most important display window for corporate brand image and city image. Known as the "Light of Asia", Asia`s first Giant LED Screen advertising is located in the center of the Guanyinqiao shopping district in Chongqing, built around the two sides of the Suning Tesco Building. This huge outdoor LED Display with a total area of 3,788 sqm combines architectural aesthetics with the business environment to showcase the prosperity of the city while keeping the pedestrian`s vision in the best viewing area Immersive experience. LED outdoor commercial display not only has the advantages of waterproof, lightning protection, anti-seismic, etc., which can be applied to various harsh environments. It can also realize regional network broadcast, and can interact with human screens such as Weibo, positioning system, infrared sensor and face recognition. Combination of technical applications. It really turns from a simple display device to a smart business company that can provide a total Giant LED Display solution. Facing the future, we will continue to grasp the core idea of [Innovation-Driven Development", give full play to the company's own advantages, and continue to develop steadily, and make unremitting efforts to build the corporate vision of "Global Audio-Visual Technology Leader".

As the technology of LED display screens continues to mature, the types of LED display screens on the market are also increasing. There are also real pixel screens, virtual screens, static screens, and scanning screens in its display effect composition. What are their respective roles in the LED display? The static screen is corresponding to the scanning screen. The static screen refers to the LED display screen displaying characters, images, and videos. The light points on the LED display screen are lighted at the same time when they are displayed; not the same as the scanning screen. Using the visual persistence feature of the human eye, each line of the LED display is lighted in a short period of time. The real pixel screen corresponds to the virtual screen. In simple terms, a real pixel screen means that each of the three kinds of red, green, and blue light emitting diodes that make up an LED display ultimately participates only in the imaging of one pixel to obtain sufficient brightness. The virtual screen is the use of software algorithms to control each color of the light-emitting tube eventually participate in the imaging of multiple adjacent pixels, so that the use of fewer lamps to achieve greater resolution, can make the display resolution about four times . As we all know, LED display is driven by the duty cycle, so the brightness of the display has a great relationship with the lighting time period. Therefore, in the same luminous tube with the same brightness, the static screen is higher than the brightness of the scan screen, so the static screen is often used outdoors in the case of high brightness display, and the scan screen is often used indoors in the situation of low brightness requirements Next, to save drive costs.

In recent years, the LED display industry has entered a high cost, low margin, high competition quagmire, although overall, LED display of the cake is more and more big, but the number of output and the enterprise growth rate of products but also not be so. It is not easy for enterprises to break the shackles and achieve greater development. To probe into the relentless competition and the endless cause of the "price war", there are many factors that contribute to the weakness of the industry's creativity and the serious homogenization of the products". Indeed, often speaking of innovation, but also in the industry "platitude" problem, it is inevitable that some people will sigh, "knowledge of the blame, the line is not easy."". Innovation, transformation, the industry has been talking about, but the specific direction and methods should be like? How can we really win the long-term development of industry and enterprises? Technological innovation: adhere to the core oriented, supplemented by shape! Throughout the course of development of LED display industry, after more than 10 years of technological innovation, has spawned a number of new products, small pitch LED display, transparent screen, special screen such as the recent hot, and the light screen, flexible screen etc.. These products, in addition to small space products for technological upgrading, most of the rest of the morphological changes, such changes for the LED display is more widely used is also very favorable. But at the same time, this phenomenon reflects the fact that technological innovations involving more central and more urgent needs are rare. As to optimize the installation process, solve the problem of heat dissipation, simplifying the operation and reduce the long time to watch the discomfort caused by the and so on, this kind of product manufacturing, stability, technology to enhance the user experience, the process is still slow. Overall, from the upgrading of LED display products, history and market demand, the core technology upgrade, innovation, the impact of more long-term and extensive. Such as the emergence of small space products, not only eliminated part of the lower definition of LED display products, but also seize a part of other display products market, driven by the current market demand. Thus, innovation involving the core technology is conducive to enhancing the overall strength and competitiveness of enterprises, and even to the overall upgrading of LED display industry, market development also has an incredible role in promoting. In addition, both the small spacing, or light screen, transparent screen and other products, the R & D and production are the views of the market application of feedback, the expression in definition, appearance and other aspects of the request, in turn, encourage enterprises to specialized development mode. Even though this kind of development mode to ensure that the market value of R & D, but also make the enterprise lack of initiative innovation consciousness, have formed a joint upstream and downstream, peripheral equipment and other parties, and in cooperation with the technical research institutes, more and more active core R & D model, limited industry innovation process. In fact, many companies do not have the ability to carry out core innovation, does that mean that they have nothing to do with innovation? Obviously not, any innovation is conducive to the promotion of products, are worthy of recognition. No product has ever been perfect since its birth, and so has the LED display. Only after the initial LED display maintenance repair, and now some manufacturers of products to do some innovative adjustment, production of LED display can be maintained, not only to expand the applications of LED display and achieve product differentiation, improve product competitiveness. Similarly, some enterprises ingenuity, research and development to produce energy-saving effects of LED display, can reduce power consumption, save costs for the user, but also become a major highlight of the product. In addition, there are some companies, with high heat dissipation performance of raw material production of LED display, the product can save cooling parts, and reduce the product due to overheating problems, greatly enhance the market competitiveness of products. In these cases, all enterprises in the warning LED display industry, innovation is not empty talk, to have the creative determination and action, can promote the performance and quality of their products to improve, so that enterprises in the advantage position in the competition. Promotion innovation: "check without this brand"? Word-of-mouth! Because the LED display industry circle is small, many manufacturers think, to expand the market, build brand image, should focus on business reputation effect, improve the industry recognition and visibility, a wide range of promotion is not essential. Undeniably, this is a precise way of promotion. Compared to the daily consumer goods, LED display is relatively narrow range of customers, too much promotion is not worth the candle. But it is such a pragmatic idea, that even in the international and domestic brands occupy a larger market share, visibility is less than some foreign brands, is not conducive to the growth of the brand construction, is not conducive to the development of the potential market. In addition, with the application of LED display more and more widely, potential customer groups also expanded, in this case, simply relying on ring reputation effect, no doubt in marketing has lost the initiative. Because people are more or less aware of preconceived ideas, it is a forward-looking propaganda to instill brand culture into potential customer groups. Not only increased brand awareness, but also virtually expanded the brand influence, the formation of enterprise soft power.

In 2018, the global market scale amount of LED display was 5.841 billion US dollars. With the increase of LED display in market demand for segmented applications such as rental market, retail department store, conference room, cinema and HDR applications, the annual compound growth rate of LED display is estimated to be 12% from 2018 to 2022. It will continue to maintain a faster growth rate, of which small pixel pitch led display is the biggest driving force for market growth. Indoor small-spacing (≤P2.5) LED display market scale was 1.197 billion US dollars in 2018, up to 39% annual growth, mainly from the continuous fermentation of small pixel pitch led display trend in the future. It is estimated that the CAGR will reach 28% from 2018 to 2022. In addition, with the maturity of small pixel pitch led display technology, outdoor led display has a tendency to gradually develop to small pitch (P3.0~P4.0). In 2018, the outdoor small-pitch market is about 155 million US dollars (35% market share), estimated to be 2018~2022. According to the fine pixel pitch led display divided by dot spacing, P1.2~P1.6 becomes the largest revenues among fine pixel pitch led display in 2018, accounting for 39%. Coupled with the gradual improvement of consumers' demand for display effects, accompanied by further decline in cost, P1.2~P1.6 and smaller pitches below P1.1 will have the most growth momentum in the next few years. The CAGR is estimated to be 32% and 62% respectively from 2018~2022. At present, the largest commercial market for fine pixel pitch LED displays comes from enterprises and education, high-end retail, hotels and theaters cultural entertainment venues. LED display currently has low penetration rate in applications industry, and there is greater growth potential to replace the traditional industries such as LCD, DLP and projection display in the future.

truths of small-pitch LED display In the past two years, the hottest topic in the LED display industry is nothing more than a small dot pitch LED display. With the decline in the price of LED packaging, the price of LED display with small dots is more approachable. Compared with liquid crystal screen (LCD) or rear projection (DLP), the small-pitch LED display has the following advantages, such as: splicing of any size without stitching, without dimming the ambient light source. In addition to LEDs, LED driver chips are also an important part for small-pitch LED displays, although many vendors claim that their LED driver chips are designed for small-pitch LED displays, but in fact they Some means still need to be used to cover up some of the defects. The following will introduce the truth and means of disguising the poor display effect when the small-pitch LED display uses an inappropriate driver chip. 1. Block unevenness and color shift (reddish) In indoor applications, the brightness of the LED display is between 300 and 1000 nits. This brightness is converted into LED forward current, which is about 1~5mA or even less than 1mA. Therefore, the small current concentration of the driving chip becomes important. When the current accuracy of the driving chip is not good, the small-pitch LED display screen is prone to uneven color blocks. However, in order to disguise the color block, the LED current is usually used to increase the brightness of the display. However, the disadvantage is that when the viewer looks at the LED display for a while, the eyes are prone to discomfort. Figure 1 demonstrates the actual difference after re-imaging the image with a small-pitch LED display that uses different quality LED driver chips. Proportionally, the forward current of green and blue LEDs is more affected by parasitic capacitance than red LEDs, so at low gray levels, the small dot pitch LED display looks reddish (red-TInt). It is the color shift we often say, as shown in Figure 2. The correct solution is to use LED driver chips with color-shift compensation instead of masking this shortcoming by increasing the LED forward current. 2. Loss of image detail at low brightness If you do not use the way to improve the forward current of the LED to cover the above shortcomings, another way is to adjust the gamma curve of the LED display with small dot spacing. The brightness of the grayscale is very important for correct image reproduction because in the video source. The medium brightness contains most of the picture data. As shown in Fig. 3. the image on the right has a small gamma value, which means that the brightness of the midtone is too high. Therefore, the overall picture is white and lacks depth, and the detail loss on the image is quite small. Compared with the left picture, the dog hair in the right picture does not. Then there are levels. 4. Bright lines or crosses caused by LED dead spots Today's LED epitaxial and packaging technology is increasing day by day, but LEDs will inevitably be damaged after a long period of use. Unlike LCD screens, broken LEDs will form bright lines or crosses at small dot-pitch LED displays. Instead of a black dot, as shown in Figure 6. It is a big problem for LED display manufacturers, operators and viewers. A good small dot pitch LED display must be able to eliminate the annoying bright lines or crosses caused by LED dead spots, as shown in the left figure of Figure 7. Only the LED driver chip with "dead pixel isolaTIon" function can maintain the normal operation of the LED display with small dot spacing, and it is convenient for the user to flexibly arrange the maintenance time. The above methods are very common in small-pitch LED displays, but limited by the knowledge and ability of buyers and users for basic image processing and LED driver chips, it is not easy to distinguish these differences and avoid the above annoying problems. The easiest way is to choose an LED driver chip designed for LED display with small dot pitch.
