LED display waterproof and moisture-proof
Ventilation and dehumidification for indoor LED display
For indoor displays, first choose moderate ventilation. Appropriate ventilation can help the water vapor adhering to the display screen to volatilize quickly and reduce the humidity of the indoor environment. Avoid the need to ventilate in windless and humid air, which will increase the humidity in the room; put a desiccant in the room, and use physical absorption to reduce the moisture in the air; or turn on the air conditioner to dehumidify, and install in the space where the display is installed It is better to install an air conditioner. You can turn on the air conditioner to perform dehumidification and other tasks in humid weather.
Outdoor LED display focuses on waterproof
The outdoor LED display is in a more complex environment than indoors. The indoor method can be used to prevent moisture. However, outdoor screens must not only consider the issue of humidity, but also need to do daily maintenance such as waterproofing, especially in rainy seasons. A good sealed installation can obviously help the display screen reduce the risk of water ingress. It is necessary to periodically remove dust attached to the display screen, and it can also help the display screen better dissipate heat and reduce the adhesion of water vapor. So the most important thing is that outdoor full-color LED display waterproofing is important to prevent during production and construction.
However, in the process of use, excessive humidity of zero components such as the PCB board, power supply, and power line of the LED display screen is more likely to cause oxidation and corrosion, thereby causing a fault condition. Therefore, we need to pay attention to the production of LED display screens. The PCB board must be anti-corrosive. For example, the surface must be coated with three anti-paints. The selected waterproof box must have good sealing performance, and the screen must reach IP65.
The welding place is very easy to be corroded. Pay attention to the protection work. The frame is particularly proposed, which is easy to rust, and it needs to be rust-proofed. For different unit board materials, a professional waterproof coating is required. Here, the outdoor P10 full-color outdoor LED display is used as an example. First confirm whether the P10 full-color outdoor unit board is attracted by magnets or screwed (the screwing effect is good, the magnet is slightly worse; see if there is a waterproof slot on the unit board kit, if it is in this case, the front waterproof is basically not large No problem, even if the unit board is fixed with a magnet.
Therefore, we also need to pay attention to the waterproof of the back panel of outdoor LED display. In the process of using the display, we can see that the back panel LED display is not only heat-dissipating, but also has a great deal of waterproof performance. Convenience. When dealing with the waterproof coating on the back, pay more attention to understanding the waterproof performance of the aluminum-plastic panel on the back of the small strip display. Under the aluminum-plastic panel, you need to design a row of water outlets with an electric drill. The heat dissipation of the display is a good way to handle the display. In the specific construction site, another duty must be implemented; the combination of prevention and drainage in the structural design; after the structure is determined, according to the characteristics of the structure, it is necessary to consider that the sealing strip material has a hollow bubble tube structure, a small permanent compression rate, Properties such as high elongation at break; after selecting the material of the sealing strip, it is necessary to appropriately design the contact surface and the contact force according to the characteristics of the materials of the sealing strip, so that the sealing strip is squeezed to a compact state. In some installations, waterproof grooves, etc., do important protection to make sure that no water will accumulate inside the display. In this way, it can be more ensured that when the display is used in the rainy season, there will be no quality problems caused by human factors.
