The LED digital display is constantly developing, and the technology is constantly being upgraded. In the future, LED digital display will develop towards thinness and high power, and LED digital display large-screen splicing technology will become more and more mature. As the development time of LED digital display is getting longer and longer, and the application fields are becoming wider and wider, users' understanding and understanding of LED digital display are also deepening, and the problems that were not understood before are gradually exposed. Speaking of which, there are still some problems in my country's LED digital display technology.


One is the lack of brightness. The main advantage of led digital screen is its strong adaptability to the changeable and complex outdoor environment. The characteristics of the outdoor environment require that the led digital display is guaranteed in sunny days, cloudy days, rainy and snowy weather, long distances and multiple viewing angles. Enough brightness to transmit information, so brightness is particularly important, and due to insufficient brightness of LEDs, LEDs can only play a supporting role in the lighting industry, mainly used for decoration, which is a huge problem for the comprehensive use of tens of thousands of LEDs. quantity. challenge.

The second is the problem of LED chromatic aberration. There is basically no chromatic aberration problem in the application of a single LED, but if multiple LEDs are used in combination, the chromatic aberration problem will become prominent. Although the existing technology can improve this problem, due to the limitation of domestic technology and production level, there are still differences between LEDs in the same color area and the same batch. This difference cannot escape the discernment of the naked eye, so it is difficult to ensure the quality of the LED digital display. . Color reproduction and realism.


The third is the LED display control chip. As a new type of display medium, true-color high-resolution digital display screen has attracted more and more attention for its clear image and high-performance playback capability. For the LED display unit, the three-color LED die is its core device, so high-quality die with small wavelength difference and good luminous intensity consistency should be selected, and this technology is mainly in the hands of world-renowned large companies, such as Japan Japan Asia Company, etc.


The fourth is heat dissipation. Since the outdoor ambient temperature changes greatly, the display itself will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work normally, or even burn out, and the display system will not work normally.


The development of any industry will encounter the bottleneck of technical difficulties, especially high-tech industries such as LED digital display. Only producers who face up to the problem can promote the development of the entire industry.
