Humid and rainy weather on led display is a big challenge, rainy season how to waterproof moisture, is the outdoor led display is facing to solve the problem, because the outdoor LED display itself in the environment is more complex than indoor, not only to consider the problem of moisture, but also to do a good job of waterproof and other routine maintenance work.
Good sealing installation can help the display to reduce the risk of water, regular cleaning of the display inside and outside attached dust, can also help the display better heat dissipation, reduce the attachment of water vapor. And moisture into the led display may cause led display dead light, so in the outdoor full-color LED display production and construction process, it is necessary to do a good job of waterproof prevention work.
First, the production and production process of waterproof work
In the production of production led display, its PCB board to do a good job of anti-corrosion treatment, such as surface coating three anti paint, etc., power supply and power cord to use high-quality accessories.
The selected waterproof case, the seal should be good, the screen must reach IP65. welding is the most vulnerable to corrosion, pay attention to do a good job of protection, especially proposed is the frame, easy to rust, do a good job of anti-rust treatment. Secondly, for different unit board materials, need to use professional waterproof coating, followed by the unit board kit on whether there is a waterproof slot, and finally, need to pay attention to the outdoor led display back waterproof problem, because, in the process of using the display, the back led display is not only heat dissipation processing, but also in dealing with waterproof performance, has great convenience. In dealing with the back waterproof coating, pay more attention to the back of the small strip display aluminum plastic plate waterproof performance, to use electric drill in the aluminum plastic plate below the design of a row of drainage, both for the display waterproof, but also for the display heat dissipation.

Second, the waterproofing work to be done on site installation and construction
In the specific construction site, in the structure design of the combination of prevention and row, after the structure is determined, according to the characteristics of the structure, can be considered with hollow bubble tube structure, compression permanent deformation rate is small, tearing elongation and other properties of the seal material, selected seal material, according to the characteristics of the seal material, the design of the appropriate contact surface and contact force, so that the seal extrusion to the dense state. In some installation, waterproof slot and other locations, do focus on protection, to ensure that the display will not have any water inside.
Third, the daily use of the process of attention
Finally, for outdoor screen, need to be used often, because the working state of the display itself will generate some heat, can evaporate some water vapor, greatly reducing the possibility of moisture caused by short circuit. led display brand manufacturers Lianchengfa recommend that you, in the rainy season LED screen display at least once a week to use more than once a month to open the screen at least once, light up more than 2 hours.

Fourth, the correct remedy for water in the led screen body.
With the fastest speed with a fan or other tools, the water into the led display screen body completely blow dry, will be completely dry screen body power aging.
Five, the operation method of power aging
Brightness (all white) adjusted to 10%, power aging 8-12 hours
Adjust the brightness (all white) to 30% and power on for 12 hours of aging.
Turn the brightness (all white) to 60% and power on for 12-24 hours of aging.
Turn the brightness (all white) to 100% and power on for 8-12 hours of aging.
VI. Notes
Do not put the LED screen body that has been in the water into the air box, so it is easy to smother the LED lights.
When the warehouse into the water, the air box may enter the water, need to be exposed to all the air box, to prevent the box after the moisture volatilization to the LED display inside.
Into the water LED display is not timely processing may affect the stability of the screen, in doing emergency treatment, the screen power may occur after the constant dead light phenomenon.
All into the water LED display screen body in the air box more than 3 days inside the screen body basic no repair value, this screen needs to be handled with caution.
