The first step for LED display to prevent moisture is to ensure that the LED module has moisture resistance.
The LED module needs to be dry and ventilated. When storing, use a pallet or other objects to raise it, and not directly contact the ground.
The storage environment is equipped with a temperature and humidity monitor, and the environmental humidity is controlled below 60 percent RH, and the LED module is very comfortable.
When the opened LED module (unit board) is stored, it needs to be repackaged and put in an appropriate desiccant.
If the LED module is stored for more than 1 month, the module will be aged for 6 hours with incremental brightness before use: the full brightness is set to 10 percent /1 hour, the full brightness is set to 30 percent /1 hour, and the full brightness is set Set it to 60 percent /2 hours, set the full brightness to 80 percent /1 hour, and set the full brightness to 100 percent /1 hour. After 6 hours of aging, it can be used for the whole screen assembly.

Outdoor LED display moisture-proof method How to prevent moisture-proof LED display
1, outdoor fixed display screen is moisture-proof
Configure a temperature and humidity monitor at the installation site of the outdoor LED display to monitor the humidity around the screen in time;
The first rainy day or after heavy rain after the screen body is installed, check whether there is moisture, water droplets, moisture, etc. inside;
Under the ambient humidity of 10 percent -85 percent RH, turn on the screen at least once a day, and each time the screen works normally for more than 2 hours;
Environmental humidity is higher than 90 percent RH or when going back to the south, the use environment of the screen should be dehumidified, and the screen should work normally for more than 4 hours a day.
2, outdoor rental screen is moisture-proof
The outdoor rental LED display is in use, and it must be powered off immediately when it rains. If you can't remove the screen, you can quickly cover it with a rain-proof cloth prepared in advance, and take out the box to dry in a sunny day. If you encounter continuous rain, open the back cover of the cabinet and use a fan to blow dry. Then leave it in a ventilated and dry room for more than 8 hours. Use low brightness to ensure that it will be on for more than 4 hours to fully dissipate the moisture in the electronic components.
Indoor LED display screen moisture-proof method
1. How to prevent moisture from indoor fixed display LED display
Under the ambient humidity of 10 percent -65 percent RH, the display screen should be turned on at least once a day, and ensure normal work for more than 4 hours each time;
If the ambient humidity is higher than 65 percent RH or when you are going back to the south, you should dehumidify the use environment of the screen and ensure that the screen works normally for more than 8 hours a day; the relevant doors and windows should be closed at night to prevent the screen from being damaged by regaining moisture at night .
2, indoor rental screens are moisture-proof
After each use, it should be immediately put into the air transfer box for sealed storage;
Each air transfer box must have a desiccant or moisture-absorbing bag of no less than 50g; and check the desiccant or moisture-absorbing bag regularly for failure, and replace it every 2 months;
Under the environment humidity of 10 percent -65 percent RH, the display screen should be taken out every half month to work (playing video) for more than 2 hours; how does the LED display screen be moisture-proof
If the ambient humidity exceeds 65 percent RH or encounters a southerly windy day, the display screen should be taken out and lighted up (playing video) for more than 2 hours a week;
During the rental and use of the screen, avoid rain or water on the screen. If it is not very wet, dry the water in time and dry it with a hair dryer. At the same time, leave the screen for 2 hours and then light up and work for 2 hours. ;
It is strictly forbidden to use indoor rental screens as outdoor rental screens, especially in open-air environments;
In short, whether it is indoors or outdoors, the most effective way to avoid damage to the function of the display screen is to use it frequently. The display screen in working condition will generate some heat, which can evaporate some water vapor, which greatly reduces the short circuit caused by humidity. Possibility. Therefore, the display screen that is frequently used has much less impact on the humidity of the display screen that is not commonly used.
