The outdoor environment can be changeable, and rainy days and greasy weather are frequent in some areas. We may all know the waterproof function is vital for outdoor LED screens, however, how waterproof LED display work?
First, let’s know some common sense for waterproof LED display screens. The key to judging the waterproof function of the display is to understand the IP (ingress protection) rating. Generally speaking, this rating of outdoor waterproof LED display should reach IP65.
IP grade consists of two numbers – the first number means the dustproof level, rating from 0 to 6, and the second number represents the waterproof level, ranging from 0 to 8. The larger the number, the better the protection grade.
Because outdoor LED screens are assembled by different amounts of outdoor LED cabinets, so the cabinet is the basic unit. Why adopt such a structure, there are mainly three reasons, they are:
1) Easy managing and on-site maintenance;
2) Easy packing and transportation;
3) Easy installation and disassembly.
For supporting waterproof function, first, the LED display module should be waterproof as it is one of the main components of the cabinet and should have a conformal coating on the surface.
Second, the cabinet should be water-resistance and should support leakproof by scientific design. The cabinet is equipped with the waterproof LED display module in front, and display driver circuit boards inside. The switching power supply and exhaust fans and so on are installed on the back cover of the box. On the inner and outer surface, the cabinet is treated with a plastic coating, which improves the functions of anti-corrosion, moisture-proof, anti-oxidation, and flame retardant, reinforcing security for the whole screen. And after serious testing, the IP rating can be concluded.
