as we all know, led display screen is divided into indoor and outdoor, indoor display screen needs moisture-proof, outdoor display screen not only needs moisture-proof, but also waterproof. if the waterproof and moisture-proof work is not in place, it is very easy to cause short circuit of the display screen, and serious fire may also be caused. therefore, in this rainstorm season faster than turning over a book, waterproof, moisture-proof led display screen is an indispensable work.
how to do a good job of anti-moisture and waterproof led display?
for the indoor display screen, the first is moderate ventilation. moderate ventilation can help the water vapor attached to the display screen evaporate rapidly and reduce the relative humidity of the indoor environment. however, avoid ventilation in windless and humid weather, which will increase indoor humidity; secondly, place drying agent in the room, reduce moisture in the air by physical moisture absorption; or turn on air conditioning to dehumidify, if air conditioning is installed in the space of display screen installation, it can be opened in wet weather. the air conditioner is dehumidified.
the environment of outdoor led display screen itself is more complex than that of indoor. moisture-proof method can be adopted indoors. but the outdoor screen should not only consider the problem of humidity, but also do daily maintenance work such as waterproofing, especially in rainy season. therefore, good sealing installation can help the display screen reduce the risk of water intake and clean up regularly. the dust attached inside and outside the display screen can also help the display screen to better heat dissipation and reduce the adhesion of water vapor.
at the same time, in the latter stage, excessive humidity causes the pcb board, power supply, power cord and other components of the led display to be easily oxidized and corroded, resulting in faults. therefore, when we make the led display, the pcb board of the led display should be well treated for corrosion protection. for example, its surface is coated with three yellow paint, power supply and power line should choose high-quality accessories, welding is the most vulnerable to corrosion, we should pay attention to the protection work, especially the framework, easy to rust, it is best to do a good job of anti-rust treatment.
finally, whether indoor or outdoor screens, the most effective way to avoid dampness damaging the function of the display screen is to use it frequently. the working status of the display screen itself will generate some heat, which can evaporate some water vapor, thus greatly reducing the possibility of short circuit caused by dampness. therefore, the humidity effect of the frequently used display screen is much smaller than that of the rarely used display screen.
