On April 20, 2018, the sixth solar term "Grain Rain" in the twenty-four solar terms arrived as scheduled. Grain Rain comes from the ancient saying that "rain gives birth to a hundred grains". The arrival of the Grain Rain solar term means that the cold wave weather is basically over, and the temperature rises faster, which also indicates that spring is coming to an end.

The most important feature of the Grain Rain solar term is “rainy”—the high-altitude westerly jet in East Asia will again weaken and move northward, the warm and humid air mass in South China is relatively active, the circulation of the westerly belt fluctuates frequently from west to east, the low pressure and the Jianghuai cyclone Activity gradually increased. Affected by this, there will be continuous rain or heavy rain in the Jianghuai region.

This season's LED display will usher in the first test after the spring: as an electronic product, it is natural to be afraid of water and tide. As an outdoor LED display, waterproof and moisture-proof is a must. High temperature, heavy humidity, and easy expansion and deformation of the device will affect the normal operation of the circuit board, resulting in dead lights, short circuits, and damage to the function and service life of the display. Therefore, for LED display users, it is the key to do a good job of moisture-proof and waterproof.

Let's talk about the moisture-proof LED display. Outdoors, the difficulty of moisture-proof LED display is much less than indoors, but it should not be underestimated. In order to avoid abnormal display of LED display caused by moisture in the air, it is recommended that you regularly clean the dust attached to the inside and outside of the display. This method It can help the display to dissipate heat better and reduce the adhesion of water vapor. At the same time, the LED display should be used frequently, because the working display itself will generate some heat, which can evaporate some water vapor, which greatly reduces the possibility of short circuit caused by humidity.

Of course, for the improper storage of unused LED display screens, the editor of Lianchengfa has also sorted out the correct remedies for you:

1. Use a fan or other tools at the fastest speed to completely dry the water-filled LED display screen.

2. Power on and age the completely dried screen. The specific steps are as follows:

a. Adjust the brightness (full white) to 10%, power on and age for 8-12 hours.

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

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

d. Adjust the brightness (full white) to 80%, and power on and age for 12-24 hours.

 water in the air box for more than 3 days have basically no repair value, please handle with caution. The editor of Liancheng Fa here reminds everyone that when using the product in the rainy season, you must pay attention to the waterproof and moisture-proof status of the product, and beware of fire accidents caused by moisture damage in the screen.
