How to prevent condensation on the LED display?

As we all know, condensation is a potential hidden danger of LED display screens, especially for components such as module connectors that do not have spray-painted waterproof components, condensation is very likely to corrode the metal material of the components, thus affecting the connection performance, which affects the display effect of the display. Outdoor led display screens are extremely prone to condensation and water droplets on the circuit board under such uncertain conditions as wind, rain, lightning and snow, high and low temperature changes outdoors, which will affect the display screen. In this case, the product life is only indoor LED display screens. about 30%. How to effectively prevent condensation and waterproof, improve the life of the display circuit board, and save repair costs has become a major problem in the quality of outdoor LED displays. Let's take a look at related solutions: Outdoor black led display display anti-condensation solution one [coating three anti-paint] Aiming at the problem of condensation on outdoor LED displays, many outdoor LED display applications in my country do not protect circuit board products, so the problem is widespread. In view of this situation analysis, the use of anti-condensation three-proof paint solution can solve the problem of circuit board condensation on the one hand, and can improve the product life on the other hand. The principle of the anti-condensation solution for anti-condensation conformal paint removal is mainly to attach a layer of micron-level anti-condensation conformal paint to the surface of the circuit board through low-concentration micron coating technology. It has extremely low surface tension, so that If not, the condensation on the circuit board will automatically slide off, thus achieving the anti-condensation effect. Outdoor led display anti-condensation solution two [electric heating method] Adopt electric heating method: add anti-condensation device inside the LED display; keep the temperature inside the display always higher than the ambient temperature outside the screen, and try to reduce the relative humidity inside the screen to completely prevent condensation inside the screen.
