How to protect the LED display from moisture and water?clear led video display screen

　　For indoor led display screen, first of all, moderate ventilation. Moderate ventilation can help the water vapor attached to the led display screen evaporate rapidly and reduce the relative humidity of the indoor environment. However, avoid ventilation in some windless and humid weather, which will aggravate the indoor humidity; Secondly, place desiccant indoors and reduce the moisture in the air by means of physical moisture absorption; Or turn on the air conditioner for dehumidification. If an air conditioner is installed in the space where the LED display is installed, the air conditioner can be turned on for dehumidification in wet weather.

　　The outdoor LED display screen itself is in a more complex environment than the indoor one. The indoor method can be used to prevent moisture. However, the outdoor LED display screen should not only consider the problem of moisture, but also do a good job of waterproof and other daily maintenance work, especially in rainy seasons. Therefore, a good sealing installation can help the display screen reduce the risk of water ingress, regularly clean the dust attached to the inside and outside of the led display screen, and also help the display screen to better heat dissipation, Reduce the adhesion of water vapor.

　　At the same time, in the later stage, the PCB board, power supply, power cord and other components of LED display screen are easy to be oxidized and corroded due to excessive humidity, resulting in failure, so this requires us to do a good job of anti-corrosion treatment for the PCB board when making LED display screen. For example, its surface is painted with three yellow paint, and the power supply and power cord should be high-quality accessories. The welding place is the most vulnerable to corrosion. Pay attention to the protection work, especially the frame, which is easy to rust, and it is best to do a good job of anti-rust treatment.

　　Outdoor LED display screen is a precision instrument. Once water enters, it may cause electric leakage and other accidents. The display screen cannot be used normally, and the service life of the display screen will also be affected after later repair. In order to prevent these consequences, we can install a waterproof slot on the display screen to drain the accumulated water in time. In addition, waterproof materials are applied on the back of the display screen, the gap and other dead corners to double waterproof.

　　If the outdoor LED display screen is used for a long time, it is prone to water seepage. Once the display screen is flooded, the power supply must be cut off immediately, and professional technicians must be sent to the site for emergency repair. During daily waterproofing, the threat of water seepage should be dealt with in time.
