For indoor display screens, first of all, moderate ventilation. Moderate ventilation can help the water vapor attached to the display to evaporate quickly and reduce the relative humidity of the indoor environment. However, avoid ventilation in some windless and humid air, which will increase the indoor humidity; secondly, place a desiccant indoors and use physical moisture absorption methods to reduce the moisture in the air; or turn on the air conditioner to dehumidify, if the display If an air conditioner is installed in the installation space, the air conditioner can be turned on for dehumidification in humid weather.

    Outdoor LED display focuses on waterproofing:

    The outdoor LED display itself is in a more complicated environment than indoors, and indoor methods can be used to prevent moisture. However, the outdoor display must not only consider the problem of moisture, but also perform daily maintenance work such as waterproofing, especially in the rainy season, so it is good The sealed installation can help the display reduce the risk of water ingress, regularly clean the dust attached to the inside and outside of the display, and can also help the display better heat dissipation and reduce the adhesion of water vapor.

    The entry of moisture may cause the LED display to die. Therefore, the most important thing is that the waterproof of outdoor full-color LED display is the most important prevention in the production and construction process.

    In the process of use, excessive humidity causes the PCB board, power supply, power cord and other components of the LED display to be more likely to be oxidized and corroded and cause failure. Therefore, when we make LED displays, the PCB board should be treated with anti-corrosion, such as coating the surface with three anti-corrosion paint, etc., and the power supply and power cord should use high-quality accessories. The selected waterproof box has good airtightness, and the screen must reach IP65. Welding is the place most likely to be corroded. Pay attention to the protection work, especially the frame, which is easy to rust, and do a good job of anti-rust treatment.

    Secondly, for different unit board materials, professional waterproof coatings are needed. Here is an example of P10 full-color outdoor LED display. First of all, confirm whether the P10 full-color outdoor unit board is magnetized or screwed (the screwing effect is good, the magnet is slightly worse); secondly, whether there is a waterproof groove on the unit board kit, if there is, the front waterproofing is basically not a big problem, even The unit board is fixed with magnets, no problem. Finally, we also need to pay attention to the waterproof problem of the backplane of the outdoor LED display, because in the process of using the display, the backplane LED display is not only a heat dissipation treatment, but also a great convenience in dealing with the waterproof performance. sex. When dealing with the waterproof coating on the back, pay more attention to the waterproof performance of the small strip-shaped display aluminum-plastic panel on the back. It is necessary to use an electric drill to design a row of drains under the aluminum-plastic panel, which is conducive to the waterproof of the display and the heat dissipation of the display. The best display processing method.

    The other part needs to be implemented in the concrete construction site; in the structural design, prevention and drainage are combined; after the structure is determined, according to the characteristics of the structure, it can be considered to have a hollow bubble tube structure, a small compression set rate, and a breaking elongation rate. Sealing strip material with large performance; after selecting the sealing strip material, it is necessary to design a suitable contact surface and contact force according to the characteristics of the sealing strip material to make the sealing strip squeeze to a dense shape. In some installations, waterproof grooves, etc., do key protection to ensure that there is no accumulation of water inside the display. Only in this way can the display screen be used in the rainy season without any quality problems caused by human factors.
