How can the outdoor LED display be effectively waterproof during the flood season?

Posted on

Heavy rains occurred in many places in Guangdong Province, and the emergency response to flooding in Guangzhou was upgraded from three to two. On the morning of the 31st, the morning peak of work, the black clouds in the urban area of ​​Guangzhou, the heavy rain poured, and many guilts in the urban area. Heavy rain continued to occur in many places in the south. In May, the situation was even worse. In the past weekend, Fujian Taining’s 2-day rainfall was nearly 300mm, and the single-day rainfall was 235.9mm, setting the largest single-day rainfall in the local record in 1956. value.

As we all know, the LED display screen is divided into indoor and outdoor, the indoor display needs to be protected from moisture, and the outdoor display not only needs moisture proof, but also waterproof. If the waterproof and moisture-proof work is not in place, it is very easy to cause a short circuit in the display screen, and serious fire may occur. Therefore, in this season when rainstorms are faster than flipping books, waterproof and moisture-proof are essential tasks for LED displays.

How to make the LED display moisture-proof and waterproof?

For indoor displays, first moderate ventilation. Moderate ventilation can help the moisture attached to the display to evaporate quickly, reducing the relative humidity of the indoor environment. However, avoid ventilating in some windless and humid air, which will increase the humidity in the room; secondly, put desiccant indoors, use physical moisture to reduce the moisture in the air; or turn on the air conditioner for dehumidification, if the display Air conditioning is installed in the installed space, and the air conditioner can be turned on in humid weather for dehumidification.

The environment of the outdoor LED display itself is more complicated than indoors, and the moisture-proof can adopt the indoor method, but the outdoor screen should not only consider the wet problem, but also do the daily maintenance work such as waterproofing, especially in the rainy season, so it is good. The sealed installation can help the display reduce the risk of water ingress, regularly clean the dust attached to the outside of the display, and also help the display to better heat dissipation and reduce the adhesion of water vapor.

At the same time, in the later process, the humidity of the LED display board, power supply, power supply line and other zero devices are more likely to be oxidized and corroded, resulting in failure, so this requires us to make the LED display when the PCB board Do anti-corrosion treatment. For example, the surface is coated with three yellow paint, etc. The power supply and power cord should be made of high-quality accessories. The welded joint is the most easily corroded place. Pay attention to the protection work, especially the frame is easy to rust, it is best to do well. Anti-rust treatment.

Finally, whether it is indoor or outdoor, the most effective way to avoid moisture damage to the display function is to use it frequently. The working display itself generates some heat and can evaporate some water vapor, which greatly reduces the amount of water. The possibility of a short circuit caused by moisture. Therefore, the frequently used display screen has a much smaller humidity effect than the less commonly used display.
