Abstract(English):

The invention relates to a vehicle-borne display screen automatic recovery system, a control method and a backlight detection circuit. The system comprises an MCU module, an ARM module, a power supply module, a TFT display screen module and a backlight detection circuit module. The MCU module is connected with the ARM module and the power supply module and is used for controlling a vehicle-borne display screen to automatically recover system work. The ARM module is connected with the MCU module and the TFT display screen module and is used for controlling the work of the TFT display module. The power supply module is connected to the MCU module and the TFT display screen module and is used for providing power supply to the TFT display screen module. One end of the backlight module detection circuit is connected to the MCU module, and the other end of the backlight module detection circuit is connected between the power supply module and the TFT display screen module. Through adding a TFT display screen backlight detection circuit in a vehicle-borne display screen control system, the functions of a product are greatly enhanced, needs of a user are satisfied, and the utilization rate of a vehicle-borne display screen is maximized, especially the utilization rate of an audio device in the display screen.
