1. Moisture-proof indoor LED display

The indoor air humidity is lower than the outdoor, so the waterproof and moisture-proof aspect is not as strict as the outdoor. The following three methods can be used to reduce the humidity.

1. Moderate ventilation. Ventilation can help the water vapor attached to the indoor LED display to evaporate quickly and reduce the relative humidity of the indoor environment. However, ventilation should be avoided when there is no wind and humid air, which can increase indoor humidity.

2. Put desiccant indoors. Use the method of physical moisture absorption to reduce the moisture in the indoor air, and the room is dry, so that you don't have to worry about the display screen getting damp.

3. Turn on the air conditioner to dehumidify. If an air conditioner is installed in the space where the LED display is installed, the air conditioner can be turned on to dehumidify in humid weather.

Second, outdoor LED display moisture-proof

The outdoor LED display should not only consider the problem of humidity, but also do maintenance work such as waterproof and dustproof. A good sealing installation can help the display reduce the risk of water ingress. At the same time, the following two methods can be used to reduce humidity.

1. Clean the dust regularly. Cleaning the dust on the surface of the casing also helps the LED outdoor display to better dissipate heat and reduce the adhesion of water vapor.

2. Frequent use. The working LED display itself will generate some heat, which can evaporate some water vapor, which can significantly reduce the possibility of short circuit caused by humidity.

In addition, before the LED display leaves the factory, the product itself must also be well waterproof, such as module glue, etc. The LED display manufacturer Liancheng Fa (LCF) produces indoor and outdoor LED displays, waterproof boxes, waterproof connectors and other designs. Advanced, the temperature range is -20 ℃ ~ 60 ℃, the box has good moisture and corrosion resistance, the product can even be used in the air environment with high humidity and high salinity by the sea.
