With the rapid development of social informationization, the use of lcd display screen is becoming more and more popular. The humid and rainy climate is a big challenge to LCD module. How to be waterproof and moistureproof in rainy season is a problem to be solved by outdoor LCD module. Because the environment of the outdoor LCD module itself is more complex than that of the indoor, not only wet problems but also waterproofing and other routine protection work should be considered. Therefore, excellent sealing equipment can help the display screen reduce the risk of water intake, regularly arrange the dust attached to the inside and outside of the display screen, and also help the display screen to better heat dissipation and reduce the adhesion of water vapor.
 
 

1. Waterproof and moisture-proof in outdoor LCD module production


In the production of LCD LCD display, the PCB board of LCD should be well anticorrosive, such as coated with three anti-paint, and the power supply and power line should choose high-quality accessories. The selected waterproof tank body has good sealing property, and it is necessary for the screen body to reach IP65. Welding is the most simple place to be corroded, we should pay attention to do a good job of protection work, especially the framework, simple rust, do a good job of anti-rust treatment.
 

2. Waterproofing of outdoor LCD Module in Installation and Construction


Next to the specific construction site; combining prevention with drainage in structural planning; after the structure is determined, according to the characteristics of the structure, the sealing strip material with hollow tube structure, small compression permanent deformation rate and large elongation at break can be considered; after selecting the sealing strip material, according to the characteristics of the sealing strip material, appropriate contact surface and contact force should be planned to extrude the sealing strip. To dense shape. In some equipment, waterproof tank and other directions, do the key protection to ensure that there is no water in the LCD screen.
 

3. Attention in the Daily Use of outdoor LCD Modules


Ultimately, with regard to outdoor LCD screens, the demand is often used, because the LCD display screen itself in working condition will generate some heat, which can evaporate some water vapor, greatly reducing the possibility of short circuit caused by wetting. Xun Rui suggests that LCD display should be used at least once a week in Meiyu season, open the screen at least once a month and light up for more than 2 hours.
