LED display application and maintenance should pay attention to the following issues：
The power supply is required to be stable and the grounding protection is good.
Do not use under harsh natural conditions (such as strong weather, etc.)
It is strictly forbidden to enter the water in the screen body, such as iron powder, which is easy to conduct. The LED display should be placed in a low-dust environment as much as possible. Large dust will affect the display effect, and too much dust will damage the circuit.
If water enters due to various reasons, please immediately turn off the power and contact the maintenance personnel until the display panel in the screen is dry before use.
LED display switching sequence:
A. Turn on the LED display after turning on the control computer to make it run normally.
B. Turn off the LED display before turning off the computer.
