Six tips for installing outdoor LED 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, with a grounding resistance of less than 3 ohms, to ensure timely discharge of high currents caused by lightning; The display screen may be subjected to strong electric and magnetic attacks caused by lightning.
2. The waterproof measures of the LED display screen itself and the junction between the screen body and the building must be strictly waterproof and leak proof; The screen should have good drainage measures, so that any accumulated water can be discharged smoothly; Pay attention to waterproofing and moisture prevention. The display screen is installed outdoors and often exposed to sunlight, rain, wind, dust, and harsh working environments. Electronic devices exposed to moisture or severe dampness can cause short circuits or even fires, leading to malfunctions or even fires, resulting in losses;
3. Select industrial grade integrated circuit chips with a working temperature between -40 ℃ and 80 ℃ to prevent the display screen from failing to start due to low winter temperatures.
4. Install ventilation equipment to cool down and keep the internal temperature of the screen between -10 ℃ and 40 ℃. Install an axial flow fan above and behind the screen to dissipate heat; The display screen itself generates a certain amount of heat during operation. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned out, causing the display system to malfunction;
5. Ultra high brightness light-emitting diodes must be selected to ensure long-distance visibility in strong ambient light; Increase contrast The audience has a wide range, with a requirement for long visibility and broad field of view; The ambient light changes greatly, especially when exposed to direct sunlight.
6. The display medium uses a new type of wide-angle tube with a wide viewing angle, pure color, consistent coordination, and a lifespan of over 100000 hours. The outer packaging of the display medium is currently the most popular square cylinder with a shielding edge, sealed with silicone, and assembled without metal; It has an exquisite and beautiful appearance, is sturdy and durable, and has the characteristics of being resistant to direct sunlight, dust, water, high temperature, and short circuit.
The installation precautions for outdoor LED display screens involve the future use and safety of the product, and must be treated strictly and seriously.
