With the improvement of LED display manufacturing technology, the resolution of traditional LED display has also been greatly improved. Small-pitch LEDs have faced many challenges since they entered the market, and they have been continuously recognized and constantly recognized in this kind of questioning. Because the small spacing can bring more rich picture and image enjoyment, and enjoy the different visual experience with the previous LED display, many dispatching command centers and monitoring centers are very concerned about it. In addition, with the increase of density, the small-pitch and high-density products have a certain substitution effect on the original indoor large-screen display, such as indoor projection, DLP and other large screen walls. However, will small-space applications in the room replace these original applications?
At this year's Infocomm show in the United States, Abbison's laser projection, Sony's COB , etc. are all very bright and have a very good display effect. At that time, some insiders speculated that our LED display industry is facing fierceness. Competition and the rapid changes in the entire environment of our industry can create subversive challenges for our industry, and small indoor spaces may be replaced.
Small indoor spaces may be replaced for a number of reasons. As for the small-pitch LED itself, when the LED display is first applied to the room, the ambient brightness is much lower than that of the outdoor, so that the brightness of the human eye must be reduced if it is not stimulated for a long time. However, as its brightness is lowered, the gradation is also subject to corresponding loss, which may result in distortion of the display content, which will inevitably have a certain impact on the user's use. Secondly, the LED display is composed of one LED light. Therefore, the problem of LED lamp bead failure is a major problem. The lower the density of the display, the more stringent the requirements of the xenon lamp rate. In addition, although the small spacing has a seamless advantage in the room, it is not inherently seamless, and the LED screen still has the problem of splicing between the module, the unit board and the box. The small-pitch screen has a high density and high requirements for seams. Therefore, how to control the seam of the display screen in the structural design and process of the display screen, truly complete the seamless screen, is still a test for the LED display. Finally, in the indoor professional application market, there will be a large amount of image data, etc., which need to be displayed on a large screen. The number of signal sources that the display needs to access is not only a large number, but also a complicated type. Therefore, the access and management of multi-signal and complex signals will also be a new problem faced by LED display manufacturers.
In summary, we can know that although the application of small pitch in indoors has a series of advantages, however, some problems of its own existence, as well as the LCD screen are constantly expanding, the brightness of laser projection is constantly improving, and the display effect is also coming. The better, and for many other reasons, it is likely to be replaced in the near future. As the LED display industry, it is necessary to objectively consider the development of small pitches, such as the failure rate of the lamp bead from the beginning of five thousandths to five millionths, and then to one millionth of the present, is a kind of Great progress. Therefore, in the face of a new round of doubts that may be replaced by small indoor distances, it is even more necessary to strengthen confidence. Finally, in order to make LED small-pitch display technology advancement, we need to work together and cooperate with the whole industry to coordinate the entire industrial chain of chips, packaging, driver ICs, cabinets, etc., and make progress together, pushing the whole industry to a higher development direction. The whole industry also needs to work together to solve the technical problems faced by small-pitch indoor applications, and jointly develop small spacing.
