Led display screens are divided into indoor led display screens and outdoor led display screens. Indoor led display screens need to be moisture-proof. Outdoor LED display screens refer to LED display screens used outdoors, which have to withstand daily strong light exposure, erosion by wind, frost, rain and snow, and lightning. , The threat of hail. In order to counter the above factors, the protective performance of the led display must be done well, among which waterproofness is an aspect that cannot be ignored. How to make the LED display screen moisture-proof and waterproof? For indoor led display screens, proper ventilation is required first. Appropriate ventilation can help the water vapor attached to the LED display to evaporate quickly and reduce the relative humidity of the indoor environment. However, avoid ventilation in some windless and humid air, which will increase the indoor humidity; secondly, put a desiccant indoors and use physical moisture absorption methods to reduce the moisture in the air; or turn on the air conditioner to dehumidify, if the led display If an air conditioner is installed in the space where the screen is installed, the air conditioner can be turned on for dehumidification 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. However, the outdoor LED display must not only consider the problem of moisture, but also perform daily maintenance work such as waterproofing, especially in the rainy season. A good sealing installation can help the display reduce the risk of water ingress, regularly clean the dust attached to the inside and outside of the led display, and can also help the display better heat dissipation and reduce the adhesion of water vapor. At the same time, in the later process, the PCB board, power supply, power cord and other components of the LED display screen are more likely to be oxidized and corroded due to excessive humidity in the later process, and cause failures. Therefore, this requires us to make the PCB board of the LED display screen. Do a good job of anti-corrosion treatment. For example, the surface is painted with three yellow paint, etc. The power supply and power cord should be made of high-quality accessories. The welding place is the most easily corroded place. Pay attention to the protection work, especially the frame, which is easy to rust, and it is best to do it well. Anti-rust treatment. Outdoor LED display is a precision instrument. Once water enters, it may cause electric leakage and other accidents. The display cannot be used normally, and the life of the display will be affected after subsequent repairs. In order to prevent these consequences, we can install a waterproof tank for the display to drain the accumulated water in time. In addition, apply waterproof material on the back of the display screen, gaps and other dead corners to double waterproof. If the outdoor LED display is used for a long time, it is prone to water seepage hazard. Once the display enters the water, the power must be cut off immediately, and professional and technical personnel should be sent to the site for emergency repairs. In daily waterproofing, the threat of water seepage must be dealt with in time. Finally, whether it is an indoor led screen or an outdoor led display screen, the most effective way to avoid damage to the function of the led display screen is to use it frequently. The display screen in the working state will generate some heat, which can evaporate some water vapor. Greatly reduce the possibility of short circuit caused by moisture. Therefore, the LED display screens that are frequently used have much less impact on humidity than the less commonly used LED display screens.
