Introduction on what to do with LED outdoor display screens in rainy weather

　　Because the outdoor LED module combined with a sealed box structure forms the LED outdoor display screen housing, which is then assembled into an outdoor LED display screen. Therefore, the LED outdoor display screen housing is the basic unit that constitutes the display screen.

　　The benefits of choosing an LED box structure are as follows:

　　1. It is beneficial for production scheduling, aging, and on-site maintenance;

　　2. It is beneficial for packaging and transportation;

　　3. It allows for convenient and quick on-site assembly and disassembly.

　　The moisture-proof housing of the LED outdoor display screen is equipped with display modules at the front, and the internal structure of the housing fixes the display system circuit board. The switching power supply circuit is installed on the rear cover of the housing. Exhaust fans and cold-pressed louvers are also installed on the rear cover. The housing is treated with plastic spraying on both the inside and outside surfaces, providing corrosion resistance, waterproofing, oxidation resistance, and flame retardancy, ensuring the safety of the display screen during operation.

　　Regarding the structure of outdoor LED display screens, the first module should be a fully moisture-proof outdoor module; the back of the second module should be coated with three-proof paint; thirdly, the housing should be moisture-proof with good sealing.

　　Outdoor housings are required to undergo waterproof testing by spraying water on the display surface. After multiple tests, the waterproof rating must reach IP65 to achieve effective moisture resistance before delivery to customers. Additionally, parts of the LED display housing that are prone to corrosion include some metal columns of the screen, circuit boards, terminal blocks, and connectors; components sensitive to water vapor include circuit boards and electronic component pins. Other components and modules are made of engineering plastics (polycarbonate), epoxy resin, plastic, etc., which have low sensitivity to water vapor.

　　How to extend the service life of LED outdoor display screens?

　　1. It is important to note the relative humidity of the air; objects containing moisture should not enter the interior of the outdoor LED display screen. If a damp outdoor LED display screen is used, the internal structural components will be corroded by outdoor water vapor, causing irreparable damage to the outdoor LED display.

　　2. Since the display screen is frequently touched by customers, regular maintenance is also very important. Regularly checking the display data and cleaning dust can improve the screen clarity of the LED advertising screen and enhance its impact.

　　3. The power supply of the display should be relatively stable with good grounding. During severe weather such as strong winds, rain, or thunderstorms, the screen should be turned off and not used.

　　4. The internal control should be turned off to avoid water and other substances increasing the conductivity of metal materials. The LED display should be placed indoors in a well-ventilated environment with good economic development and low smoke and dust. Coarse particulate smoke not only reduces display performance but also seriously affects the circuit operation of the LED display.
