With the rapid development of society, the use of LED display screen is becoming more and more common. Wet and rainy weather is a great challenge to LED display screen. How to be waterproof and moisture-proof in rainy season is a problem to be solved by outdoor LED display screen. Because the environment of outdoor LED display is more complicated than that of indoor, we should not only consider the problem of humidity, but also do the routine maintenance work such as waterproof, so a good sealing installation can help the display screen to reduce the risk of influent. Regular cleaning of internal and external dust screen can also help the display better heat dissipation, reduce the adhesion of water vapor.
1. Waterproofing in the production process
In the production of LED display screen, its PCB plate to do a good corrosion prevention treatment, such as surface coating, such as three anti-paint, power supply and power cord to choose high-quality accessories. The selected waterproof box should be well sealed and the screen must reach IP65.. Welding is the most vulnerable to corrosion, we should pay attention to the protection work, especially proposed is the frame, easy to rust, rust prevention treatment.
2. Waterproof work to be done in site installation and construction
In the concrete construction site, the combination of prevention and arrangement in the structural design; after the structure is determined, according to the characteristics of the structure, we can consider the sealing strip material with the characteristics of hollow bubble tube structure, small compression permanent deformation rate, high elongation at break, etc. After selecting the sealing strip material, the suitable contact surface and contact force should be designed according to the characteristics of the sealing strip material, so that the seal strip can be squeezed into a compact shape. In some installation, waterproof tank and other locations, do key protection to ensure that there is no water inside the screen.
3. Attention in the course of daily use
Finally, for outdoor screens, they need to be used frequently, because the working state of the screen itself will produce some heat, can evaporate some of the water vapor, greatly reduce the possibility of short-circuit caused by moisture. Xincai Chen recommends that you use the LED screen at least once a week during the rainy season, turn on the screen at least once a month, and light up for more than 2 hours.
