How to prevent condensation on outdoor advertising displays?

  For outdoor advertising display, once there is condensation, it is equivalent to produce a potential hidden danger, especially for module connectors and other components that do not have the coating spray three waterproof, condensation is very likely to parts of the metal material corrosion, which affects the performance of the connector, affecting the outdoor advertising display display effect. After all, in the outdoor this kind of wind, rain, lightning, snow, high and low temperature changes and other uncertainty, the circuit board is extremely easy to cause condensation, water droplets, thus affecting the outdoor advertising display, in this case the product life is only indoor LED display 30% or so. Then you knowOutdoor Advertising DisplayHow to prevent condensation? The following is a small introduction from VisiTech:

  Methods of preventing condensation on outdoor advertising displays are as follows:

  1、Coating three-proof paint

  For outdoor advertising display condensation problem, many of China's outdoor LED display applications do not do circuit board product protection, so the problem prevails. For this situation analysis, the use of anti-condensation three-proof paint solution, on the one hand dissatisfied with the circuit board condensation problem, on the other hand can improve the life of outdoor advertising display. The principle of the anti-condensation solution using three-proof paint removal is mainly through the low concentration of micron coating technology, so that the circuit board surface attached to a layer of micron-level thickness of anti-condensation three-proof paint, which has a very low surface tension, in this case, the condensation on the circuit board will automatically slide down, so as to achieve the effectiveness of the anti-condensation.

  2、Electric heating method

  In the outdoor advertising display screen to join the anti-condensation device, so that the temperature inside the outdoor advertising display screen is always higher than the ambient temperature outside the screen, and try to reduce the relative humidity inside the outdoor advertising display screen, thus completely preventing the screen to produce condensation.

  In summary, is the outdoor advertising display anti-condensation methods, we through these methods, can effectively anti-condensation, waterproof, so as to effectively improve the life of the outdoor advertising display circuit board.
