As we all know, LED display is divided into indoor and outdoor, indoor display needs moisture-proof, outdoor display not only need moisture-proof, as well as waterproof. If waterproof, moisture-proof-proof work is not in place, it is extremely likely to cause a short circuit, serious may also cause a fire, etc.. So, in this storm faster than the open book of the season, waterproof, moisture-proof is the essential work of LED display.
How to do LED display moisture-proof, waterproof?
For indoor display, the first moderate ventilation. Moderate ventilation can help the water vapor attached to the display screen to evaporate quickly, reducing the relative humidity of the indoor environment. However, avoid in some wind and humid weather ventilation, this will increase the indoor humidity; secondly, placed desiccant indoors, with moisture-proof to physics, reduce the moisture-proof in the air; or open air conditioning dehumidification, if the screen is mounted in the space to install air conditioning, you can turn on the air pumping damp weather wet.
The outdoor LED display itself environment than the complex indoor, indoor moisture-proof can take the method, but the outdoor screen should not only consider the damp problem, but also make daily maintenance of waterproof work, especially in the rainy season, so a good seal installation can help the display screen to reduce the influent risk, regular cleaning and display attached to the dust, can also help to display better heat dissipation, reduce adhesion of water vapor.
At the same time, late in the process, PCB board, LED display the humidity caused by power supply, power line etc components will be easily oxidized corrosion, and the failure, so this requires us to make the LED display, the PCB board to do anti-corrosion treatment. For example, the coating of Sanhuang paint, power supply and power line to use high quality accessories, welding is the most susceptible to corrosion in place, should pay attention to the protection work, especially the frame, easy to rust, rust treatment do best.
Finally, whether indoor or outdoor screen screen. The most effective way to avoid the wet damage function is often used to display, the working state of display itself will generate some heat, some water vapor can be evaporated, thus greatly reducing the possibility of short-circuit caused by damp. Therefore, the regular use of the display, the relative humidity of the display screen is not much smaller.
