We know that the lamp of led display are MSD components (humidity sensitive devices), so this is a big challenge for led display in wet and rainy weather. So how to deal with the problem of preventing the mositure and water into led display?
Indoor led display should pay attention to the ventilation and dampness.
For the indoor display, the first thing is ventilation moderately. Moderate ventilation can help quickly evaporate the water vapor that has attached to the display so that to reduce the relative humidity of the indoor environment. However, to avoid ventilation in some windless and humid weather, this will increase the indoor humidity; Secondly, put desiccant in the indoor environment, with physical moisture absorption method to reduce the air in the water; or open the air conditioning for dehumidification, if the display Installed where there has an air conditioning, you can open theit in humid weather for dehumidification.
Outdoor LED display focuses on waterproofing
The outdoor LED display itself is more complex than the indoor in environment, we can apply the indoor anti-moisture methods to handle the same problem. However, the outdoor screen not only to consider the damp problem, but also do waterproof and other routine maintenance work, especially in the rainy season. Thus, well sealed installation can help to reduce the risk of water. Besides, clean the dust that was attached on the led display regularly can also help to dissipate heat better, reduce the water vapor attached.
The prevention in the process of production and construction is the most important thing in outdoor full color LED display waterproofing.
In the process of using led display, over-moisture can cause PCB board, power supply, power lines and other devices of led display are more easily oxidized corrosion, and failure. Under these requirements, we need PCB board to do anti-corrosion treatment, such as the surface coated with three anti-paint, to use high-quality accessories between power lines. We need to choose the waterproof cabinet with sealing performance, and the protection level must be reached to IP65.
Second, for different cell board materials, we need to use a professional waterproof coating.
Finally, whether it is indoor screen or outdoor screen, to use it frequenly is the most effective way to avoid the destruction of the screen function, since the working state of the display itself will produce some heat, which can be some of the steam evaporated, so it can greatly reduced Dampness causes the possibility of short circuit. Therefore, the often used display screen, relatively less commonly used display humidity is much smaller. Industry insiders recommend that in the rainy season LED screen display for at least once a week, at least once a month to open the screen once, lit for more than 2 hours.
