Users who use outdoor led display screens know that condensation is a big killer of outdoor display screens, especially some connecting parts that are not waterproof. These parts will not get wet by water when it rains, but they cannot prevent condensation. . If condensation occurs, it is extremely likely to cause corrosion to these components. After a long time, it will directly affect the use of the LED display panel. In some cities with relatively high humidity, due to the relatively large temperature change, the circuit board and various components Condensation is prone to appear on the above, and the water droplets condensing from the inside are particularly likely to cause permanent damage to the internal components. In this case, the service life of outdoor led display screens can be shortened by 30 percent to 50 percent , which will cause great damage to the company's property.
How to effectively prevent outdoor led display condensation and improve the service life of the display is an important daily work. Doing a good job in daily work can not only extend the service life, but also greatly save after-sales maintenance costs. Based on years of working experience, Bobangcheng has summarized some solutions to deal with outdoor display condensation:
In view of the condensation problem of outdoor led display screens, many outdoor led display screen applications in our country have not done circuit board product protection, so the problem is widespread. In view of the analysis of this situation, the use of anti-condensation three anti-paint solutions, on the one hand, solves the problem of circuit board condensation, on the other hand, it can increase the life of the product.
The principle of the anti-condensation solution for the removal of anti-condensation three-anti-paint is mainly through low-concentration micron coating technology, so that a layer of micron-thickness anti-condensation three-anti-paint is attached to the surface of the circuit board, which has extremely low surface tension, so Otherwise, the condensation on the circuit board will automatically fall off, thus achieving the anti-condensation effect.
Using the electric heating method: adding an anti-condensation device inside the LED display; keeping the temperature inside the display higher than the ambient temperature outside the display, and reducing the relative humidity inside the display as much as possible to prevent condensation inside the display.
