After years of research and development experience in full-color LED Displays, EAGER LED has summarized the following main problems of Outdoor LED Displays:
(1). The LED display is installed outdoors, often exposed to the sun, rain, wind and dust, and the working environment is harsh. Electronic equipment being wet or severely damp can cause short circuit or even fire, cause failure or even fire, and cause loss;
(2). The LED display may be attacked by strong electricity and strong magnetism caused by lightning;
(3). The ambient temperature changes greatly. 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;
(4). The audience is wide, the viewing distance is long, and the field of vision is wide; the ambient light changes greatly, especially if it is exposed to direct sunlight.
In response to the above special requirements, Outdoor LED Displays must:
(1). 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 accumulated water occurs, it can be discharged smoothly;
(2). Install lightning protection devices on LED displays and buildings. The main body and the shell of the 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;
(3). Install ventilation equipment to cool down so that the internal temperature of the screen is between -10°C and 40°C. An axial fan is installed on the top of the back of the screen to discharge heat;
(4). The display medium adopts a new type of wide viewing angle tube, which has a wide viewing angle, pure color, consistent coordination, and a life span of over 100,000 hours. The outer packaging of the display medium is currently the most popular rectangular tube with a cover, sealed with silicone, and no brutalized assembly; its appearance is exquisite and beautiful, sturdy and durable, with protection from direct sunlight, dust, water, high temperature, and circuit short circuit “Five defenses” features.
