With the improvement of LED display manufacturing technology, the resolution of traditional LED displays has also been greatly improved. Small-pitch LEDs have faced many doubts since they entered the market, and they have continued to grow and be recognized amidst such doubts. Because small spacing can bring richer pictures and image enjoyment, and it also has a different visual experience from previous LED displays, many dispatching command centers and monitoring centers are paying great attention to it. In addition, as the density of small-pitch high-density products increases, they have a certain substitution effect on the original indoor large-screen displays, such as indoor projection, DLP and other spliced large-screen walls. However, will the indoor application of small spacing replace these original applications?
At this year’s Infocomm exhibition in the United States, Absen’s laser projection and Sony’s COB were eye-catching and had very good display effects. Therefore, some people in the industry speculated that our LED display industry is now facing fierce competition and the rapid changes in the entire industry environment. These may cause disruptive challenges to our industry, and indoor small spacing may also be replaced.
Indoor small spacing may be replaced for many reasons. As for the small-pitch LED itself, first of all, when the LED display is used indoors, the ambient brightness will be much lower than outdoors. Therefore, in order to achieve long-term viewing without irritation to the human eye, the brightness must be reduced. However, as the brightness decreases, the gray scale will also suffer a corresponding loss, which will lead to distortion of the display content, which will inevitably have a certain impact on user use. Secondly, the LED display screen is composed of LED lights one by one, so the problem of LED lamp bead failure is a major problem it faces. The smaller the density of the display screen, the more stringent the requirements for the blind rate indicator. In addition, although small spacing has the advantage of being seamless indoors, it is not inherently seamless. LED screens still have splicing problems between modules, unit boards, and boxes. The density of small-pitch screens is high, and the requirements for seams are also high. Therefore, how to control the seams of the display in terms of structural design and process of the display to truly make the entire screen completely seamless is still a test for LED displays. Finally, in the indoor professional application market of small spacing, there will be a massive amount of image data that needs to be displayed on a large screen. The signal sources that the display needs to access are not only large in number, but also complex in type. Therefore, the access and management of multiple signals 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 spacing indoors has a series of advantages, however, it has some problems of its own, as well as the continuous expansion of LCD screens, the continuous improvement of laser projection brightness, and the better and better display effects. It is likely to be replaced in the near future. As for the LED display industry, we need to look at the development of small spacing objectively. For example, the failure rate of lamp beads has increased from 500,000 to 5 million, and now to 1 million, which is a huge progress. Therefore, in the face of a new round of doubts that indoor small spacing may be replaced, we must strengthen our confidence. Finally, to make LED small-pitch display technology progress, we need the entire industry to work together, cooperate with each other, and coordinate the entire industry chain such as chips, packaging, driver ICs, and cabinets to make progress together and push the entire industry to a higher development direction. The entire industry also needs to work together to solve the technical problems faced by indoor applications of small spacing and jointly develop small spacing.
