with the rapid development of society, the use of led display screen is becoming more and more common. the humid and rainy weather is a big challenge to the led display screen. how to be waterproof and moisture proof in rainy season is a problem to be solved for outdoor led display. because the environment of outdoor led display is more complex than that of indoor, we should not only consider humidity, but also do daily maintenance work such as waterproofing, so a good sealing installation can help the display reduce the risk of water intake, regularly clean up the dust attached to the inside and outside of the display screen, and also help the display screen disperse better. heat reduces the attachment of water vapor.
i. waterproofing in the production process
in the production of led display screen, its pcb board is well anti-corrosion treatment, such as three anti-paint on the surface, power supply and power line should choose high-quality accessories. selected waterproof tank body, good sealing, screen body must reach ip65. welding is the most easily corroded place, we should pay attention to the protection work, especially the framework, easy to rust, do a good job of anti-rust treatment.
2. waterproofing work to be done in site installation and construction
in the specific construction site; the combination of prevention and drainage in structural design; 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, the sealing strip material should be designed according to the characteristics of the sealing strip material. appropriate contact surface and contact force make the sealing strip extrude to compact shape. in some installation, waterproof tank and other positions, do the key protection to ensure that there is no water accumulation inside the display screen.
3. attention in daily use
finally, for the outdoor screen, it needs to be used frequently, because the working status of the display screen itself will produce some heat, can evaporate some water vapor, greatly reducing the possibility of short circuit caused by humidity. it is recommended that you use the led screen at least once a week during the rainy season, turn on the screen at least once a month and light it for 2 hours.
