LED display is an important carrier of visual display. Due to the uneven R&D and production technologies of various brand manufacturers, blind spots and black screens often occur, partly due to the poor thermal performance.

The heat dissipation design of led display is very important. Due to the heat exchange area between the heating electronic components and the cold air, the temperature difference between the heating electronic components and the cold air will directly affect the heat dissipation effect. In the air volume design of LED display screen, the design of air duct is more critical. When designing ventlation pipes, try to use straight pipes to convey air, avoiding sharp turns and bends. Sudden expansion or contraction of ventilation pipes shall be avoided.

Long term high load operation is the main reason for the huge heat dissipation of the internal structure of most LED displays. The heat dissipation quality directly affects the service life and working efficiency of the display module. Generally speaking, according to the heat dissipation mode of radiator, it can be divided into active heat dissipation and passive heat dissipation. Active cooling is the forced removal of heat emitted by radiator through cooling equipment such as fans; The so-called passive heat dissipation means that the splicing light source of the large heat source screen naturally dissipates heat into the air through the radiator, and its heat dissipation effect is similar to that of the radiator. It is proportional to the size of the radiator.

At present, the high brightness LED full color screen on the market usually adopts natural heat dissipation. By increasing the surface area of the radiator and the structure of the product, the heat dissipation is increased and the accumulated temperature is reduced. Intelligent dimming system, through the background control system, LED display can perform intelligent dimming according to the time period and ambient brightness, which not only plays the role of energy conservation and emission reduction, but also reduces energy consumption and heat dissipation. In the design of the internal structure of LED display screen, a more transparent design idea is adopted, especially the outdoor display screen, which can play a role in rapid heat dissipation.
