In order to keep the outdoor led display in a long-term normal operation state, engineers will consider many possible problems during design and installation, such as the following:
The main problems of outdoor screens are as follows:
(1) 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;
(2) The display screen may be attacked by strong electricity and 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) Wide audience area, long viewing distance and wide field of view are required; the ambient light changes greatly, especially it may be exposed to direct sunlight.
In response to the above special requirements, outdoor display screen display screens 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 water accumulation occurs, it can be discharged smoothly;
(2) Install lightning protection devices on display screens and buildings. The main body and 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 flow fan is installed above the back of the screen to discharge heat;
(4) Select an industrial-grade integrated circuit chip with an operating temperature between -40 °C and 80 °C to prevent the display from being unable to start due to the low temperature in winter. ;
(5) 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.
(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 life span of more than 100,000 hours. The outer packaging of the display medium is currently the most popular square cylinder with a cover, sealed with silicone, and without metallized assembly; its appearance is exquisite and beautiful, durable, and has the functions of preventing direct sunlight, dustproof, waterproof, high temperature and short circuit Five defense features.
