Display apparatus driving method, display apparatus, and electronic device

A method for driving a display apparatus, the display apparatus comprising a face detector, the method comprising:

• obtaining, based on a trigger signal, a distance value between the display apparatus and a user that is acquired by a distance detector when a user face is detected by the face detector;
• determining whether the distance value is within a preset range;
• and
• controlling a near-infrared light emitter of the display apparatus to emit near-infrared light, if the distance value is within the preset range, wherein the near-infrared light is used to heat a skin of the user,
• wherein a display region of the display apparatus comprises at least two near-infrared light working zones used for irradiating the user face, and when the user face moves in front of the display apparatus, the display apparatus is configured to:
• determine a target near-infrared light working zone facing the user face, based on distance values acquired by distance detectors in the plurality of near-infrared light working zones;
• obtain a distance value between the target near-infrared light working zone and the user that is acquired by the distance detector;
• and
• control a near-infrared light emitter in the target near-infrared light working zone to emit the near-infrared light and control a near-infrared light emitter in a near-infrared light working zone other than the target near-infrared light working zone to stop emitting the near-infrared light.
