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.

Abstract: A sleep intervention equipment, system and method are provided. The sleep intervention equipment includes a physical sign detection device, a first processor, and a sleep intervention device. The first processor is communicatively connected to the physical sign detection device and the sleep intervention device, respectively. The physical sign detection device is configured to detect a user's physical information without touching the user, and send the physical information to the first processor. The first processor is configured to determine a sleep stage and/or breath state of the user according to the physical information, and send a corresponding control instruction to the sleep intervention device according to the sleep stage and/or breath state of the user. The sleep intervention device is configured to perform a corresponding sleep intervention behavior in response to the control instruction. The sleep stage includes a waking state, an approaching waking state, or a sleep state.
