Display panel, control method thereof, and display device

A display device, comprising

• a display panel including a display area and a non-display area, a base substrate, and touch electrodes on a side of the base substrate facing a light-exiting surface of the display panel, wherein the display area includes a first display area and a second display area that at least partially surrounds the first display area, the touch electrodes are at least distributed in the display area, the touch electrodes at least include a first touch electrode located in the first display area, the first touch electrode includes at least one first touch electrode unit, and the first touch electrode unit includes at least one hollowed part, along a direction perpendicular to the base substrate, the hollowed part runs through the first touch electrode unit, and the first touch electrode is a self-capacitive touch electrode;
• and
• a light-capturing component,
• wherein:
• the light-capturing component is located on a side of the display panel away from the light-exiting surface;
• the light-capturing component includes a light-capturing unit;
• and
• an orthographic projection of the light-capturing unit on the base substrate falls within a range of an orthographic projection of the hollowed part of the first touch electrode unit on the base substrate.

A control method of a display panel, comprising:

• a first touch stage and a second touch stage, wherein:
• the display panel includes a display area and a non-display area, a base substrate, and touch electrodes on a side of the base substrate facing a light-exiting surface of the display panel, wherein the display area includes a first display area and a second display area that at least partially surrounds the first display area, the touch electrodes are at least distributed in the display area, the touch electrodes at least include a first touch electrode located in the first display area and a second touch electrode in the second display area, the first touch electrode includes at least one first touch electrode unit, and the first touch electrode unit includes at least one hollowed part, along a direction perpendicular to the base substrate, the hollowed part runs through the first touch electrode unit, and the first touch electrode is a self-capacitive touch electrode;
• in the first touch stage, a touch detection is performed on the first display area, wherein a touch detection signal is sent to the first touch electrode unit including at least one hollowed part in the first display area, and a touch sensing signal is received through the first touch electrode unit;
• and
• in the second touch stage, a touch detection is performed on the second display area, wherein a touch detection signal is sent to the second touch electrode located in the second display area, and a touch sensing signal fed back by the second touch electrode in the second display area is received.
