1. Install lightning protection devices on LED display screens and buildings: the main body and shell of the LED display screen are well grounded, and the grounding resistance is 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 display screen 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: select industrial-grade integrated circuit chips whose working temperature is between -40°C and 80°C 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 body is between -10 °C and 40 °C: Install an axial flow fan above the back of the screen body to discharge heat; the display screen itself will generate a certain amount of heat when it is working. 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.
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; increase the contrast. Variations are large, especially when exposed to direct sunlight.
6. The display medium adopts a new type of wide viewing angle tube: wide viewing angle, pure color, consistent coordination, and life expectancy of more than 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.
The installation precautions of outdoor LED display involve the future use and safety of the product, and must be treated strictly and seriously.
