Installation requirements and precautions for outdoor led wall screen display indoor display screens:
1. Install lightning protection devices on display screens and buildings. The main body and shell of the display screen should be well grounded, and the grounding resistance should be less than 3 ohms, so that the large current caused by lightning can be discharged in time; the display screen may be attacked by strong electric and magnetic fields caused by lightning
2. The screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, and once water accumulation occurs, it can be discharged smoothly; pay attention to waterproof and moisture-proof. The display screen is installed outdoors, often exposed to the sun and rain, the wind blows the dust cover, and the working environment is harsh. Wet or severely damp electronic equipment can cause short circuits or even fires, causing failures or even fires, resulting in losses;
3. Select industrial-grade integrated circuit chips with a working temperature between -40°C and 80°C to prevent the display from being unable to start when the temperature is too low in winter.
4. Install ventilation equipment to cool down, so that the internal temperature of the screen is between -10°C and 40°C. An axial flow fan is installed on the back of the screen body to discharge heat; when the display screen is working, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned, so that the display system cannot work normally. Work;
5. In order to ensure long-distance visibility under strong ambient light, ultra-high brightness light-emitting diodes must be selected; increase contrast, wide audience, long viewing distance, and wide field of view; ambient light changes greatly, especially if it is likely to be affected by sunlight direct shot.
6. The display medium adopts a new type of wide viewing angle tube, which has a wide viewing angle, pure colors, consistent coordination, and a service life of more than 100,000 hours. The outer packaging of the display medium is the most popular square cylinder with a cover, silicone seal, and no metallized assembly; Exquisite and beautiful appearance, sturdy and durable, with the characteristics of anti-sunlight, dust-proof, waterproof, high-temperature-proof, circuit-short-proof
