Due to environmental factors, the brightness of the outdoor LED screen and the protection IP level of the back and side of the screen are higher than those of the indoor screen, not only rainproof, but also dustproof, high temperature proof, wind proof, lightning proof, etc., while the indoor screen does not need to consider these Question, the IP protection level is composed of two digits: the first digit represents the level of the lamp from dust and foreign objects intrusion, the second digit represents the degree of airtightness of the lamp against moisture and waterproof intrusion, and the larger the number, the higher the protection. The higher the level.

Judging from the current demand in the rental market, the mainstream of outdoor LED displays is PH4mm products, referred to as P4 for short. Although the outdoor displays are all waterproof boxes with good sealing performance, in the process of use, due to weather and environmental reasons, it is inevitable that The PCB board, power supply, power cord and other parts of the LED display are easy to oxidize and corrode, so the usual maintenance is very important.

Since the outdoor screen is rain-proof, high-temperature proof, and lightning-proof, is it suitable for any weather? The answer is no! The power load of the LED display screen is relatively large. In extreme weather, it is easy to cause leakage, conduction, collapse, etc. Safety accidents, so it is recommended to cut off all power sources as soon as possible before the arrival of heavy rain or windy weather, and do a good job in the reinforcement of the display shelf to prevent the occurrence of safety accidents.
