Get waterproof and moisture-proof method for rainy day LED display

With the rapid development of society, the use of LED displays is becoming more and more common. Humid and rainy weather is a big challenge for LED displays. How to waterproof and moisture-proof in rainy seasons is a problem to be solved for outdoor LED displays. Since the environment of the outdoor LED display itself is more complicated than that of the indoor, not only the moisture problem must be considered, but also daily maintenance such as waterproofing should be done. Therefore, a good sealing installation can help the display screen reduce the risk of water ingress, and the display screen should be cleaned regularly. The dust attached to the inside and outside of the screen can also help the display to dissipate heat better and reduce the adhesion of water vapor.

1. Waterproof work in the production process. When producing LED display screens, the PCB board should be treated with anti-corrosion treatment, such as coating the surface with conformal paint, etc., and high-quality accessories should be selected for the power supply and power cord. The selected waterproof box has better sealing performance, and the screen body must reach IP65. Welding is the place that is most likely to be corroded. Pay attention to protection work, especially the frame, which is easy to rust, so do a good job of anti-rust treatment.

2. The waterproof work required for on-site installation and construction is in the specific construction site; the structural design is combined with waterproofing; after the structure is determined, according to the characteristics of the structure, it can be considered to have a hollow bubble tube structure, a small compression set rate, Sealing strip materials with high elongation at break; after selecting the sealing strip material, it is necessary to design a suitable contact surface and contact force according to the characteristics of the sealing strip material, so that the sealing strip can be squeezed to a dense state. In some installations, waterproof grooves and other positions, do key protection to ensure that there will be no water accumulation inside the display. 3. Attention during daily use Finally, outdoor screens need to be used frequently, because the display screen itself in working state will generate some heat, which can evaporate some water vapor, greatly reducing the possibility of short circuit caused by humidity.

Xin Caichen recommends that you use the LED screen display at least once a week during the rainy season, turn on the screen at least once a month, and light it for more than 2 hours. .
