The installation of outdoor LED display involves the future use and safety of the display, so what problems should we pay attention to when installing LED display?  

1. Install lightning protection devices on LED display screens and buildings: The main body and shell of the LED 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 affected by strong electricity caused by lightning. Magnetic attack.


2. Waterproof measures for the LED display itself: the screen body and the junction of the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, so that water can be discharged smoothly in the event of water accumulation; pay attention to waterproof and moisture-proof. The LED display is installed outdoors, often exposed to the sun and rain, and the wind blows the dust cover, and the working environment is harsh. Wetting or serious damping of electronic equipment can cause short circuit or even fire, causing failure or even fire, resulting in losses.


3. Circuit chip selection: choose industrial-grade integrated circuit chips with operating temperature between -40℃~80℃ to prevent the display screen from being unable to start due to the low temperature in winter.


4. Install ventilation equipment to cool down, so that the internal temperature of the screen is between -10°C and 40°C: install an axial flow fan above the back of the screen to discharge heat; the LED display itself will generate a certain amount of heat when it is working. If the ambient temperature is too high High and poor heat dissipation, the integrated circuit may not work properly, or even be burned, so that the display system can not work properly.


5. Ultra-high brightness light-emitting diodes must be selected: in order to ensure long-distance visibility in the case of strong ambient light, ultra-high-brightness light-emitting diodes must be selected; the contrast is increased. Variations are large, especially when exposed to direct sunlight.


6. The display medium adopts a new type of wide viewing angle tube: the viewing angle is wide, the color is pure, consistent and coordinated, and the outer packaging of the display medium is the most popular square cylinder with a cover edge, which is sealed with silicone and has no metallization assembly; its life span exceeds 100,000 hours. The appearance is exquisite and beautiful, strong and durable, and has the characteristics of five preventions: direct sunlight, dustproof, waterproof, high temperature resistance, and circuit short circuit prevention.
