1. In order to prevent direct lightning strikes, install lightning rods on the support structure of the LED display (outdoor), indoor LED display or LED display with tall buildings next to it.led display wall ， There is no need to consider installing lightning rods.
2. In response to the counterattack of the steel structure, connect the rigid structure to the shell of the LED display screen, do equipotentiality, and do a good job of grounding. Ground resistance is generally required to be less than 10 ohms. If the resistance value does not meet the requirements, an artificial grounding grid can be installed. The arrester should also be grounded.
3. For the lightning current induced on the signal line, install the signal lightning protection device on the signal line. The signal arrester depends on the signal interface of the system. If it is a network cable, install a network signal arrester, and install a DB9 interface arrester on the serial port. The cross-sectional area of the ground wire should not be less than 1.5mm square.
