How to use the car screen 1. Switching order: When turning on the screen, turn on the computer first, then turn on the screen; when turning off the screen, turn off the screen first, then turn off the computer (turning off the computer first without turning off the display will cause bright spots on the screen, burn the lamp, and have serious consequences.)

3. The screen can be turned on and powered on only after the computer enters the engineering control software.

7. When a line appears very bright on a part of the LED electronic display screen, pay attention to turning off the screen in time. It is not suitable to turn on the screen for a long time in this state.
