Rainy Day Display Waterproof And Moisture Proof Method
- Jan 15, 2019 -

With the rapid development of society, the use of LED displays is becoming more and more common, and the wet and rainy weather is a big challenge for LED displays. How to waterproof and dampproof in the rainy season is a problem to be solved by outdoor LED displays. Since the environment of the outdoor LED display itself is more complicated than the interior, not only the wet problem but also the daily maintenance work such as waterproofing is required, so a good sealed installation can help the display reduce the risk of water ingress, and regularly clear the display. Dust attached to the inside and outside of the screen can also help the display to better dissipate heat and reduce the adhesion of water vapor.

First, the waterproof work of the production process

When manufacturing and producing LED display screens, the PCB boards are treated with anti-corrosion treatment, such as three anti-paints on the surface, and high-quality accessories for power and power lines. The waterproof box is selected for better sealing and the screen must reach IP65. The weld is the most vulnerable place to be corroded. Pay attention to the protection work, especially the frame, which is easy to rust and anti-rust treatment.

Second, the waterproof work required for on-site installation and construction

In the specific construction site; in the structural design, the combination of prevention and drainage; 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, and a large elongation elongation. Strip material; after selecting the sealing strip material, it is necessary to design suitable contact surface and contact force according to the characteristics of the sealing strip material, so that the sealing strip is squeezed to a compact shape in some installations, waterproof grooves, etc., to make key protection. Make sure there is no water inside the display.

Third, attention in the daily use process

Finally, for outdoor screens, it needs to be used frequently, because the working display itself generates some heat, which can evaporate some water vapor, greatly reducing the possibility of moisture causing short circuit. Xin Caichen recommends that you use the LED screen display at least once a week during the rainy season, and at least once a month, and light up for more than 2 hours.
