As we all know, condensation is a potential LED display hidden dangers, especially for module connectors and other parts do not have to spray three waterproof, condensation is most likely to corrosion of parts of metal materials, thus affecting the plug Of the performance, affecting the display of the display. Outdoor LED display in the outdoor wind and thunder and lightning, high and low temperature changes and other uncertain circumstances, the circuit board is extremely easy to cause condensation, water droplets, thus affecting the display, in which case the product life is only indoor LED display Of about 30%.
How to effectively prevent condensation, waterproof, improve the life of the display circuit board, saving cost of repair has become a large outdoor LED display quality problems, so for outdoor led display in a harsh environment easy to condensation, short life problems, we a Look up the relevant solution:
Outdoor LED display anti-condensation solution one [painted three anti-paint]
For outdoor LED display condensation problems, many of our outdoor LED display applications are not done circuit board product protection, so the problem is widespread. In view of this situation, the use of anti-condensation three anti-paint solution, on the one hand, the circuit board condensation problem, on the other hand can improve product life. The principle of anti-condensation solution is mainly through the low concentration of micron coating technology, so that the surface layer of the circuit board attached to a layer of micron-level thickness of the anti-condensation three anti-paint, it has a very low surface tension, so that , Then the circuit board will automatically fall on the condensation, so as to achieve the anti-condensing effect.
Outdoor LED display anti-condensation solution two [electric heating method]
The use of electric heating way: in the LED display inside the anti-condensation device; so that the internal temperature of the display screen is always higher than the ambient temperature outside the screen, and try to reduce the relative humidity inside the screen, it can prevent the screen to produce condensation.
