What are the methods for making outdoor LED displays waterproof?

The waterproofing methods for outdoor LED displays mainly involve the production process, on-site installation and construction, as well as daily usage.
During the production process, ensure that the PCB board undergoes anti-corrosion treatment, such as surface coating of three-proof paint, etc., and select high-quality power supplies and power lines. Use waterproof boxes with good sealing performance, and the screen body reaches the IP65 standard. Special attention should be paid to the rust prevention treatment of the frame. For different unit board materials, use professional waterproof coatings and ensure that the unit board kits have waterproof grooves. At the same time, pay attention to the waterproof problem of the back plate, as the back plate not only handles heat dissipation but also bears the responsibility of waterproofing. When processing the waterproof coating on the back side, pay attention to the waterproof performance of the aluminum-plastic board, and design a row of drainage outlets, which is beneficial for waterproofing as well as heat dissipation.
During on-site installation and construction, design a structure that combines prevention and drainage, select sealing strip materials with specific performance, design appropriate contact surfaces and forces according to the material characteristics, and make the sealing strip compress to a dense state.
During daily use, outdoor LED displays are frequently used. The heat generated during operation can evaporate water vapor, reducing the possibility of short circuits caused by dampness. It is recommended to use the LED display screen for at least 2 hours or more every week during the rainy season to maintain the normal operation of the display.
