As for outdoor LED display, there is no doubt that we need to do some waterproof measures for it. The waterproof measures must be done at both the LED module part, and the LED cabinet part.
In this article, I'm going to introduce how we acheive that at led module part:
a. For the LED modules, all LED pins which contact the PCB, are sealing with silicon glue, so that the rain water can’t insinuate into the module inside, the silicon glue will protect the circuit from short out or damage. Look at the following pictures and get a more intuitive feeling. Above the silicon glue, there are still to install a module mask, this is not only dual waterproof, but also protect the LEDs from man-made damage and to enhance the contrast of led display.
b. When the LED modules are install on the cabinet, between the modules and cabinet there must be tightly coupling without any gap. The waterproof rubber ring is the best solution for this, as the rubber rings have good strong bounce and durable. With pressing tight between the led module and cabinet, there is no worry about the water leaking in.
