With the development of LED display time, the application field is more and more wide, and the understanding and awareness of LED display is deeper. The problem that has not been understood before is gradually revealed. From the technical point of view, China's LED display technology mainly has the following problems: First, the problem of insufficient brightness The main advantage of LED display is the super adaptability to the complex and complex outdoor environment. The characteristics of the outdoor environment require that the LED display should be sufficient in sunny, cloudy, rainy and snowy weather, long distance and multiple viewing angles. Brightness is used to transmit information, so brightness is especially important. Due to insufficient LED brightness, LEDs can only act as supporting roles in the lighting industry, mainly for decoration. This is a huge challenge for the comprehensive application of tens of thousands of LEDs. Second, the LED color difference problem There is basically no chromatic aberration problem in the application of a single LED, but if a large number of LEDs are used in combination, the chromatic aberration problem will be highlighted. Although there are techniques to improve this problem, due to the limitations of domestic technology and production level, there are still differences in the same batch of LEDs in the same color zone, and this difference is difficult to escape the eye-catching, so it is difficult to ensure the color of the LED display. Reducive and realistic. Third, LED display control chip True color high-resolution led electronic display as a new display media, with its clear image and high-performance playback capabilities, has been increasingly valued by people. For the LED display unit, the three-primary LED dies are the core components, so high-quality dies with small wavelength differences and good luminous intensity should be used, and this technology is mainly in the hands of world-renowned companies, such as Japan's Nichia company, etc. Fourth, heat dissipation Because the outdoor environment temperature changes greatly, coupled with the display itself, it must generate a certain amount of heat. If the ambient temperature is too high and the heat is not good, it will probably cause the integrated circuit to work abnormally or even be burned, thus making the display system impossible. normal work.
