With the continuous development of LED electronic screen, although there are many LED display manufacturers, the technology upgrading may be consistent. In the future, Shenzhen’s LED display has ultra-thin, high output, LED display large screen connection technology, and is becoming more and more mature. With the growth of LED electronic screen and the expansion of its application field, the understanding of LED electronic screen is becoming deeper and deeper, and the situation of unknown problems is gradually revealed. At present, there are the following problems in LED display technology in China
First, insufficient brightness. The main advantage of LED electronic display is that it has strong adaptability to complex outdoor environment. As the characteristic of outdoor environment, LED electronic display must ensure sufficient brightness to transmit information in sunny, cloudy, rainy, long-distance and multi view. Therefore, due to the lack of LED brightness, LED is only used as a supporting role in the lighting industry, mainly for decoration, and using tens of thousands of LEDs at the same time is a greater challenge.
The second is led color difference. Single LED is almost no color difference problem applications, but when using multiple LEDs at the same time, the color difference problem is obvious. Although there are technologies to improve this problem, due to the limitations of domestic technology and production level, there are still differences in the same led placed on the same color area, and because it is difficult to see these differences with the naked eye, it is difficult to ensure the color restoration and fidelity of LED electronic screen.
Third, LED display control chip. True color high-resolution LED electronic display is a new display medium with clear image and high-performance playback function, so it has attracted more and more attention. For LED display equipment, three color LED core is the core equipment, so high quality core with small wavelength and uniform brightness intensity must be used. This technology is mainly used in the hands of world-famous large enterprises, such as Japan’s Japan Asia.
Fourth, febrile. The rapid temperature change of outdoor environment will produce specific heat when the display screen is running. If the environment temperature is too high and the heat is poor, the integrated circuit may not work normally, or it may be burned, and the display system may not work normally.
In any industry, will encounter technical problems of wooden bottles, especially LED electronic large screen and other high-tech industries. Mini optoelectronic is always in the LED electronic screen research and innovation, face up to and solve these problems, promote the development of the whole industry.
