As we all know, LED display is one of the most widely used large screens in the world. It covers a wide range of fields. Whether it is indoor or outdoor display, it occupies a large market, such as some outdoor advertising large screens and transparent screens in shopping malls. , Indoor exhibition hall small-pitch led display screen, etc., but in the process of its application, we also found some problems, if it can be improved, the led display screen will be more perfect.

First, the cost of indoor small-pitch LED display
The display effect of the indoor small-pitch LED display can be said to be perfect. The entire large screen will not produce blur or discomfort regardless of whether it is viewed from close or far. However, its cost is very high, with more than 100,000 yuan per square meter. It is cheap and also more than 10,000 square meters. How to reduce the cost of construction so that the user can accept it will make the application of small-pitch led display screens more common.
Second, the problem of heat dissipation
Because the outdoor environment temperature changes greatly, and the display itself generates a certain amount of heat when it is working. If the ambient temperature is too high and the heat dissipation is poor, it will likely cause the integrated circuit to work abnormally or even be burned, so that the display system cannot work normally, so the heat dissipation of the large LED display screen should be one of the key solutions.

Third, the problem of insufficient brightness
In the ever-changing outdoor environment, the LED display must be able to ensure sufficient brightness to transmit information, so the brightness is particularly important. Due to the insufficient brightness of the LED lamp beads, the current LED lamp beads can only act as a supporting role in the lighting industry. For decoration, this will be a huge challenge for the comprehensive use of tens of thousands of LED lamp beads. High-brightness outdoor LED displays may be the leader.
Fourth, the chromatic aberration problem of led lamp beads
In the application of a single LED lamp bead, there is basically no chromatic aberration problem, but if a large number of LED lamp beads 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 technology and production level, there are still differences in the same color zone and the same batch of LED lamp beads, and this difference is difficult to escape the naked eye, so it is difficult to ensure the LED display screen. Color reproduction and fidelity.
