Whether it is outdoor LED display or indoor LED display, it is very important to do a good job of waterproof and moisture-proof to avoid losses due to weather factors or human operation. If the waterproof and moisture-proof work is not in place, it may cause short circuit of the display screen, or even fire.

As far as the structure of outdoor full-color LED display screen is concerned, first, the module should be outdoor full waterproof module, second, the back of the module should be painted with three proofing paint, and third, the box should be waterproof box with good sealing.

 

Waterproof test is required for all outdoor boxes. Sprinkle water on the surface of the display screen to test. After several tests, ensure that the protection level reaches IP65, so as to achieve real waterproof, and finally deliver the goods to the customer. In addition, the perishable parts of the structural parts of the LED display box generally include metal columns, circuit boards, terminal blocks and connectors of the screen body; Components sensitive to water vapor are circuit boards and electronic component pins. Other parts are engineering plastics (polycarbonate), epoxy, rubber, etc., which are insensitive to water vapor.

At present, more and more customers have more requirements on the waterproof box structure of LED display screen, and begin to develop into thin and light boxes that are easy to disassemble. However, from a professional perspective, it is not completely closed and thin that can certainly play a waterproof role. The box structure only plays a role in dust prevention and foreign matter prevention. Small space is not convenient for heat dissipation, and large area of water inflow is not conducive to treatment and maintenance. The above solutions are solutions for traditional outdoor LED display.

 

Method of waterproof and moisture-proof for 3 LED displays

Moderate ventilation

Moderate ventilation can help the water vapor attached to the indoor LED 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.

Place desiccant indoors

The method of physical moisture absorption is used to reduce the moisture in the air and dry the room, so that the LED display screen will not be affected with moisture.

 

Turn on the air conditioner for dehumidification

If an air conditioner is installed in the space where the indoor LED display is installed, the air conditioner can be turned on for moisture extraction in humid weather.

If the LED display screen is not often used, the manufacturer of the LED display screen reminds everyone that in the plum rain season, the LED display screen should be used at least once a week, turned on at least once a month, and lit for more than 2 hours to prevent damage to the LED display screen.
