In practice, improving the heat dissipation performance of LED displays not only effectively improves the heat dissipation efficiency of LED displays, but also achieves the effect of power saving, which is more conducive to improving the service life of LED displays.

1. Fan cooling, using a long-lasting and efficient fan inside the lamp housing to enhance heat dissipation, is a commonly used method with low cost and good results.

2. The use of aluminum heat sink is the most common way of heat dissipation, using aluminum heat sink as a part of the shell to increase the heat dissipation area.

3. Aerohydrodynamics utilizes the shape of the lamp shell to generate convective air, which is the lowest cost method for enhancing heat dissipation.

4. Surface radiation heat dissipation treatment: The surface of the lamp shell needs to undergo radiation heat dissipation treatment. A relatively simple method is to apply radiation heat dissipation paint, which can carry away the heat on the surface of the lamp shell with radiation.

5. Integration of thermal conductivity and heat dissipation - Using ceramics with high thermal conductivity, the heat dissipation of the lamp housing is to reduce the working temperature of LED high-definition display chips. Due to the large difference in the expansion coefficient between LED chips and the metal thermal conductivity and heat dissipation materials we often use, it is not possible to directly weld LED chips to avoid damage to LED display chips due to high and low temperature thermal stress.

6. Heat pipe heat dissipation uses heat pipe technology to transfer heat from the LED display chip to the shell heat sink.

7. The thermal conductive plastic shell is filled with commercial thermal conductive materials by injection, thereby increasing the thermal conductivity and heat dissipation capacity of the plastic shell.

It can be seen that the maturity and progress of LED display screen heat dissipation technology will be conducive to its energy-saving and environmentally friendly concept. There are various ways for LED electronic display screen manufacturers to improve the heat dissipation of LED display screens when producing them. Heat dissipation may have different considerations depending on the power level and usage location.
