How to keep the LED screen safe in the rainy season

How to keep the LED screen safe in the rainy season

The LED electronic display screen is divided into indoor and outdoor. The indoor display needs to be moisture-proof, and the outdoor display needs not only moisture-proof, but also waterproof. Otherwise, it is very easy to cause a short circuit of the display screen, and it may cause a fire in serious cases. Therefore, in this season when the rainstorm is faster than turning over a book, waterproof and moisture-proof are essential tasks for the LED display.

So, how to make the LED display moisture-proof and waterproof?

For indoor displays, first, moderate ventilation. Moderate ventilation can help the water vapor attached to the display to evaporate quickly and reduce the relative humidity of the indoor environment. However, avoid ventilation in some windless and humid weather, which will increase the indoor humidity; secondly, place a desiccant indoors and use physical moisture absorption to reduce the moisture in the air; or turn on the air conditioner to dehumidify, if the display screen If an air conditioner is installed in the installation space, the air conditioner can be turned on to dehumidify in humid weather.

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

At the same time, in the later process, excessive humidity causes the PCB board, power supply, power cord and other components of the LED display to be easily oxidized and corroded, resulting in failure, so this requires us to make the LED display, its PCB board. Do a good job of anti-corrosion treatment, such as coating the surface with three-yellow paint, etc., and use high-quality accessories for the power supply and power cord. The welding place is the most likely to be corroded. Rust, it is best to do a good rust treatment.

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