Abstract: A driving control apparatus, a driving control method and a display apparatus. When a display panel is in a power-on state and it is determined that a user leaves the display panel, a backlight stop signal (VBN) is first output, and a voltage stop signal (VPN) is then output. A backlight control circuit (320) stops operating in response to the backlight stop signal. In response to the voltage stop signal, a power switching circuit (330) stops outputting a driving voltage for driving the display panel to display a picture. When determining that the user returns to the front of the display panel, a voltage start signal (VPQ) can first be output, and a backlight start signal (VBQ) is then output. The backlight control circuit starts to operate in response to the backlight start signal. The power switching circuit outputs the driving voltage in response to the voltage start signal.
