The main technical problems of small-pitch LED display
Date: 2019-09-28
Undoubtedly, the development of any industry will encounter the bottle of technical problems, especially high-tech industries such as LED display. Only when producers face up to the problem can they promote the development of the entire industry. Jinghui Smart Optics will analyze the following main problems of LED display:
1, the problem of insufficient brightness.
The main advantage of the small-pitch LED display is the super adaptability to the complex and complex outdoor environment. The characteristics of the outdoor environment require the LED display to be guaranteed on sunny, cloudy, rainy and snowy weather, long distance and multiple viewing angles. Sufficient brightness to transmit information, so brightness is especially important, and due to insufficient LED brightness, LEDs can only act as supporting roles in the lighting industry, mainly for decoration, which is a huge comprehensive application for tens of thousands of LEDs. challenge.
2, 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.
3, the LED display control chip.
True color high-resolution LED electronic display as a new display medium, with its clear image and high-performance playback capabilities, has been increasingly valued by people. For the LED display unit, the three primary color 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 large companies.
4, 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.
