1. The panel of the outdoor LED display screen and the joint between the panel and the building must be strictly waterproof and leak-proof, and good drainage measures must be taken in the screen body. Once water accumulates, it can be drained smoothly.

2. Install lightning protection devices on outdoor LED displays and buildings. The monitor body and the shell are well grounded, the grounding resistance is less than 3 ohms, and large currents are discharged in time when lightning strikes.

3. Install a ventilation device to lower the temperature to -10~40℃, so that the internal temperature of the outdoor led display screen will drop. The axial fan installed behind the panel dissipates heat.

4. Use industrial integrated circuit chips whose operating temperature is between -40 and 80 degrees to avoid the low temperature in winter, which may cause the led screen to start.

5. In order to be able to see far in the strong ambient light, the outdoor LED display must choose ultra-high brightness LED.

6. The outdoor LED display media adopts a new wide-view mirror tube, which has a wide viewing angle, pure color, consistent coordination, and a service life of more than 100,000 hours. The outer packaging of the display medium is currently the most popular square tube with shielding function, sealed with silicone, and assembled without metallization. The appearance is exquisite and beautiful, sturdy and durable, and has the "five prevention" functions such as direct sunlight, dustproof, waterproof, high temperature, and circuit short circuit.
