Entering the spring, the south will usher in the "return to the south", and then will enter the "rainy season". In this season, water can be squeezed out of the air. If the pervasive water vapor stays in the LED display, it will cause dead lights and dim lights. , short circuit, open circuit and lamp body damage, etc., resulting in performance failure! Therefore, in order to ensure that the LED display can shine beautifully in wet weather, we must do a good job of preventing moisture in the spring.
LED module (unit board) moisture-proof method
The first step in the moisture-proof LED display is to ensure that the LED module has moisture-proof function.
The LED module needs to be dry and ventilated. It should be raised with pallets or other objects during storage, and should not be in direct contact with the ground.
Install a temperature and humidity monitor in the storage environment, control the ambient humidity below 60 percent RH, and the LED module is very comfortable.
When the unsealed LED module (unit board) is stored, it needs to be repackaged and put in a suitable desiccant.
If the storage time of the LED module exceeds 1 month, the brightness of the module should be gradually increased and aged for 6 hours before use: the full brightness is set to 10 percent /1 hour, the full brightness is set to 30 percent /1 hour, the full brightness is set The setting is 60 percent /2 hours, the full brightness is set to 80 percent /1 hour, and the full brightness is set to 100 percent /1 hour. After 6 hours of aging, it can be used for the whole screen assembly.
Moisture-proof method of outdoor LED display
1. Outdoor fixed display is moisture-proof
1) Configure a temperature and humidity monitor at the installation site of the outdoor LED display to monitor the humidity around the screen in time;
2) After the first rainy day or heavy rain after the screen is installed, check whether there is damp, water droplets, water vapor, etc. inside in time;
3) Under the ambient humidity of 10 percent 85 percent RH, open the screen at least once a day, and each time the display works normally for more than 2 hours;
4) If the ambient humidity is higher than 90 percent RH or encounters returning to Nantian, dehumidify the use environment of the screen body, and ensure that the display screen works normally for more than 4 hours a day.
2. Moisture-proof outdoor rental screen
When the outdoor rental LED display is in use, it must be powered off immediately in case of rain. If it is too late to dismantle the screen, use the prepared rain cloth to cover it quickly. When it is sunny, take the box out to dry. If it encounters continuous rain, it is necessary to open the back cover of the box and use a fan to dry it with cold air. Then hang in a ventilated and dry room for more than 8 hours. The low brightness is guaranteed to be lit for more than 4 hours, and the moisture in the electronic components is fully emitted.
Moisture-proof Dafa of Indoor LED Display
1. Moisture-proof indoor fixed display
1) Under the ambient humidity of 10 percent to 65 percent RH, the display screen should be turned on at least once a day, and each time to ensure normal work for more than 4 hours;
2) If the ambient humidity is higher than 65 percent RH or when returning to Nantian, the use environment of the screen body should be dehumidified, and the display screen should work normally for more than 8 hours a day; the relevant doors and windows should be closed at night to prevent the screen from returning moisture at night. body damage.
2. Moisture-proof indoor rental screen
1) After each use, it should be immediately put into an air transfer box for sealed storage;
2) In each air transport box, there must be no less than 50g of desiccant or moisture-absorbing bag; and the desiccant or moisture-absorbing bag must be checked for failure regularly, and it needs to be replaced every 2 months;
3) Under the ambient humidity of 10 percent 65 percent RH, the display screen should be taken out every half month to light up (play video) for more than 2 hours;
4) When the ambient humidity exceeds 65 percent RH or encounters southerly winds, the display screen should be taken out to light up (play video) for more than 2 hours per week;
5) During the rental and use of the screen, the screen should be prevented from being exposed to rain or water. If it is not very wet, it should be wiped dry in time and dried with a hair dryer. At the same time, the screen should be placed for 2 hours before lighting up. 2 hours of work;
6) It is strictly forbidden to use the indoor rental screen as an outdoor rental screen, especially in the open air environment;
In short, whether it is indoors or outdoors, the most effective way to avoid moisture damage to the function of the display is to use it frequently. The working display itself will generate some heat, which can evaporate some water vapor, which greatly reduces the short circuit caused by humidity. possibility. Therefore, the frequently used display screen has much less humidity effect than the less commonly used display screen.
In this wet season, it is necessary to choose a display screen with moisture-proof function, choose a good screen and use the correct moisture-proof method, your led display screen will be able to display perfectly without fear of wet weather.
