LED Display Technology Upgrade Direction

The development of LED displays continues, although there are many LED display manufacturers, but the direction of technology upgrade is probably the same, the future of LED displays tends to thin, high power, LED display large screen splicing technology is becoming more mature. As the development time of LED display screens has increased and the application field has become more and more widespread, the people’s awareness and awareness of LED displays has also become deeper, and those who did not understand the problems have gradually emerged. From the aspect of technology, At present, China's LED display technology mainly has the following problems:

One is the lack of brightness. The main advantage of LED display is the super adaptability to the changing and complex outdoor environment. The characteristics of the outdoor environment require the LED display to ensure sufficient in sunny, cloudy, rain and snow weather, long-distance, multi-angles. The brightness transmits information, so the brightness is particularly important, and due to the lack of LED brightness, the current LED can only act as a supporting role in the lighting industry, mainly for decoration, which for the comprehensive application of tens of thousands of LED is a huge challenge.

The second is the LED color difference problem. The application of a single LED, there is basically no problem of color, but the comprehensive use of many LEDs, color problems will be highlighted. Although there are technologies to improve this problem, due to limitations in domestic technology and production levels, there is still a difference in the same batch of LEDs in the same color zone, and it is difficult for this difference to escape the nuisance of the naked eye, and it is difficult to ensure the color of the LED display. Reducibility and fidelity.

The third is the LED display control chip. As a new display medium, true-color high-resolution LED electronic display has received more and more attention due to its clear image and high-performance playback capability. For LED display units, three-color LED dies are the core devices. Therefore, high-quality dies with small wavelength differences and good luminescence intensity consistency should be used. Such technologies are mainly held in the hands of world-famous companies, such as Japan's Nichia Corporation.

The fourth is heat dissipation. Because the outdoor environment temperature changes greatly, plus the display itself must generate a certain amount of heat, if the ambient temperature is too high and coupled with poor heat dissipation, it will most likely cause the integrated circuit to work abnormally, or even burned, so that the display system can not normal work.

The development of any industry will encounter the bottleneck of technical problems, especially the high-tech industries like LED display. Only when producers face the problem can they promote the development of the entire industry.
