There is no doubt that the development of any industry will encounter technical problems, especially high-tech industries like LED displays. Only when producers face up to the problem can they promote the development of the entire industry. Below, Fly-LED LTD will analyze the main problems of LED screens technically for everyone.
One is the problem of insufficient brightness. The main advantage of the LED display is its strong adaptability to the ever-changing and complex outdoor environment. The characteristics of the outdoor environment require that the LED display be sufficient in sunny, cloudy, rainy and snowy weather, long-distance, and multiple viewing angles. Brightness is used to convey information, so brightness is particularly important. Due to the lack of LED brightness, LEDs can only serve as supporting roles in the lighting industry, mainly for decoration. This is a huge challenge for the comprehensive use of tens of thousands of LEDs.
The second is the problem of LED color difference. The application of a single LED basically has no chromatic aberration problem, but if a large number of LEDs are used in a comprehensive manner, the chromatic aberration problem will become prominent. 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 color zone and the same batch of LEDs, and this difference is difficult to escape the naked eye, so 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 screens have attracted more and more attention with their clear images and high-performance playback capabilities. As for the LED display unit, the three-primary color LED die is its core device, so high-quality die with small wavelength difference and good luminous intensity consistency should be used, and this technology is mainly in the hands of world-renowned large companies.
The fourth is heat dissipation. Because the outdoor environment temperature changes greatly, and the display itself has to generate a certain amount of heat when it is working, if the environment temperature is too high and the heat dissipation is poor, it will likely cause the integrated circuit to work abnormally or even be burned, making the display system unable to normal work.
