What should I do if the outdoor LED screen is flooded

by JohnsonZhong on August 19, 2022

The wet and rainy weather is a big challenge to the LED screen. How to waterproof and moisture-proof in the rainy season is the problem that the outdoor LED screen faces to be solved. Because the environment of the outdoor LED screen itself is more complicated than that of the indoor, it is not only necessary to consider the humidity It is necessary to do daily maintenance work such as waterproofing.

A good sealing installation can help the display screen to reduce the risk of water ingress. Regularly clean the dust attached to the inside and outside of the display screen, and it can also help the display screen to dissipate heat better and reduce the adhesion of water vapor. And the entry of moisture may cause the LED screen to die, so in the production and construction process of the outdoor full-color LED screen, it is necessary to do waterproof prevention work.



  1. Waterproofing in the production process

When making and producing LED screen, the PCB board should be treated with anti-corrosion, such as coating the surface with three anti-paint, etc., and the power supply and power cord should use high-quality accessories.

The selected waterproof box has better sealing performance, and the screen body must reach IP65. Welds are the most easily corroded places, so we should pay attention to the protection work, especially the frame, which is easy to rust, so we should do a good job of anti-rust treatment. Secondly, for different unit board materials, professional waterproof coatings need to be used, and secondly, whether there is a waterproof groove on the unit board kit, and finally, attention should be paid to the waterproof problem of the backplane of the outdoor LED screen, because in the process of using the display In the middle, the back panel LED screen is not only heat dissipation, but also has great convenience in dealing with waterproof performance. When dealing with the waterproof coating on the back, pay more attention to the waterproof performance of the aluminum-plastic panel of the small strip display on the back. Use an electric drill to design a row of drains under the aluminum-plastic panel, which is not only conducive to the waterproofing of the display, but also to the heat dissipation of the display.


  1. Waterproofing work for on-site installation and construction

In the specific construction site, the structure design should be combined with prevention and drainage. After the structure is determined, according to the characteristics of the structure, it can be considered to have a hollow foam tube structure, a small compression set rate, and a large elongation at break. Strip material, after selecting the sealing strip material, it is necessary to design the appropriate contact surface and contact force according to the characteristics of the sealing strip material, so that the sealing strip is extruded to a dense state. In some installations, waterproof grooves and other locations, do key protection to ensure that there is no accumulation of water inside the display.


  1. Attention during daily use

Finally, for outdoor screens, it needs to be used frequently, because the working screen itself will generate some heat, which can evaporate some water vapor, greatly reducing the possibility of short circuit caused by humidity. Lianchengfa, a brand manufacturer of LED screen screens, recommends that you use the LED screen display at least once a week during the rainy season, and turn on the screen at least once a month for more than 2 hours.



4.the correct remedy for water into the LED screen:

Use a fan or other tools at the fastest speed to completely dry the water-infused LED screen screen, and energize the completely dried screen body to age.


Five, the operation method of power-on aging

The brightness (full white) is adjusted to 10%, and the power is aged for 8-12 hours.

Adjust the brightness (full white) to 30%, power on and age for 12 hours.

Adjust the brightness (full white) to 60%, power on and age for 12-24 hours.

Adjust the brightness (full white) to 100%, power on and age for 8-12 hours.



  1. Matters needing attention

Do not put the LED screen body that has entered the water into the air box, it is easy to suffocate the LED lights.

When the warehouse is filled with water, the air box may enter the water, and all the air boxes need to be exposed to the sun to prevent the water from volatilizing into the LED screen after packing.

If the LED screen screen with water is not dealt with in time, it may affect the stability of the screen body. During emergency treatment, the phenomenon of continuous dead lights may occur after the screen body is powered on.

All LED screen screens that have entered the air box for more than 3 days are basically of no repair value. Such screens need to be handled with care.
