Up for days, guangdong cool rain, as we all know, the LED display is divided into indoor and outdoor, indoor display need to moistureproof, outdoor display not only need to moistureproof, and waterproof. If waterproof, moistureproof work does not reach the designated position, extremely easy to cause display circuit, serious still could cause fire, etc. So, under the heavy rain season, faster than the books of waterproof, moistureproof work is an essential part of LED display. How to do the LED display of moisture-proof, waterproof? For indoor display, appropriate ventilation in the first place. Appropriate ventilation are attached to the display screen can help moisture evaporate quickly, reduce the relative humidity of the indoor environment. However, avoid wet weather in some without wind and air ventilation, it can aggravate the indoor humidity; Second, put desiccant indoors, by physical absorption of moisture, reduce the moisture in the air; Wetted or open air conditioning, if installed display space of air conditioning, is can be wetted wet weather open air conditioning. And outdoor LED display itself more complicated than the indoor environment, moisture can adopt the method of indoor, outdoor screen but should not only consider the damp problem, but also to waterproof and so on daily maintenance work, especially in the rainy season, so a good seal installation can help reduce the risk of water display screen and regular cleaning screen internal and external dust adhesion, can also help screen better heat dissipation, reduce the adhesion of water vapor. At the same time, in the process of late, humidity cause LED display PCB, power supply, power supply cord zero device is easy to oxidation corrosion, and failure, so it requires that we make the LED display screen, the PCB good anticorrosive processing. Such as its three yellow paint coating, etc. , the power and the power cord to choose high quality accessories, welding place is the place where the most easy to corrode, attention should be paid to do a good job protection, is put forward by the special frame, easy to rust, better be antirust processing. Finally, whether indoor screen or outdoor screen, the most effective way to avoid moisture damage of display function is often used to display the working state of their own will produce some heat, can some water vapor evaporates, thus greatly reduce the possibility of a damp cause a short-circuit. Often use display screen, therefore, is relatively commonly used display humidity influence is much smaller.
