  • Drainage system:

Set up a complete drainage system around the display screen to ensure that rainwater can be drained quickly to avoid damage to the display screen caused by accumulated water.

Through properly designed drainage ditches, drainage holes, and other structures, accumulated water can be quickly guided to a safe area and a dry environment around the display screen can be maintained.

3). Thunder and lightning weather response strategies

  • Lightning protection equipment:

Thunder and lightning weather pose a serious threat to the safety of LED displays. Installing lightning protection equipment such as lightning rods and lightning protection strips above or near the display screen can introduce lightning into the ground and effectively protect the display screen from lightning damage.

These lightning protection devices can quickly guide lightning current underground to prevent lightning from directly hitting the display screen and ensure its safe and stable operation.

  • Power outage protection:

In thunder and lightning weather, timely cutting off the power supply of the display is an effective protection measure. By cutting off the power supply, you can prevent lightning from entering the display through the power cord and causing damage.

After the thunderstorm is over, reconnect the power supply to ensure that the display can work normally.
