LED display will generate a certain amount of heat in the working process, if the heat dissipation is poor, it will affect the performance and life of the display. You may find that the screen appears to flicker, spend screen and other phenomena, or the life of the display is significantly shortened.

There are several main reasons for poor heat dissipation. 

One is the unreasonable design of the display. If the heat dissipation structure of the display is poorly designed, or the heat dissipation area is not enough, it will result in the heat not being able to be emitted in time. 

Second, the ambient temperature is too high. If the ambient temperature in which the display is located is too high, and the heat dissipation system is unable to effectively reduce the temperature, poor heat dissipation will occur. 

Third, long time continuous work. If the display works continuously for a long time, the heat generated will continue to accumulate, thus leading to more serious heat dissipation problems.

In order to solve the problem of poor heat dissipation, first of all, in the design of the display, we should give full consideration to the problem of heat dissipation, and adopt reasonable heat dissipation structure and heat dissipation materials to ensure that the heat can be emitted in a timely manner. In the process of use, pay attention to the control of environmental temperature, avoid placing the display in a high temperature environment. 

At the same time, to avoid prolonged continuous work, you can arrange appropriate rest time, so that the display has enough time to dissipate heat. In addition, you can also regularly clean and maintain the display to ensure the normal operation of the cooling system.
