In summer, we should not only pay attention to the heat dissipation, but also the waterproof problem of outdoor LED screen box. Let's share how to waterproof the LED screen.
The waterproof of display screen mainly lies in prevention. The selected module should be outdoor waterproof module, the back of the module should be painted with three anti paint, and the selected led screen box should also be waterproof led screen box, with good sealing performance. The other part needs to be implemented in the specific construction site. In the structural design, prevention and drainage are combined. After the structure is determined, according to the characteristics of the structure, the sealing strip material with hollow bubble tube structure, small compression permanent deformation rate and large elongation at break can be considered.
After selecting the sealing strip material, the appropriate contact surface and contact force should be designed according to the characteristics of the sealing strip material to make the sealing strip compact. In some installation, waterproof tank and other positions, do key protection to ensure that there is no water inside the display box.
Secondly, for different unit board materials, professional waterproof coating is needed, here is the example of P10 outdoor LED display screen outside the user. First, confirm whether the P10 outdoor unit board is magnet adsorption or screw (the effect of screw is good, the magnet is slightly poor); second, whether there is a waterproof slot on the unit board kit, if there is one, then the front waterproof is basically not a big problem, even if the unit board is fixed by magnet.
Finally, we also need to pay attention to the waterproof problem of the back panel of outdoor led screen box, because in the process of using the display panel, the back panel LED display panel is not only heat treatment, but also has great convenience in dealing with the waterproof performance. When dealing with the waterproof coating on the back, pay more attention to the waterproof performance of the aluminum-plastic plate of the small strip display screen on the back. A row of water outlets should be designed under the aluminum-plastic plate with an electric drill, which is not only conducive to the waterproof of the display screen, but also conducive to the heat dissipation of the display screen. It is the best way to deal with the display screen.
