Display panel and electronic device

An electronic device, comprising:

• a display panel, comprising:
• a display layer, wherein the display layer comprises a non-pixel area and a plurality of pixel areas, and a light-emitting component is disposed in each pixel area of the plurality of pixel areas, wherein
• the display panel comprises a display area, and the display area comprises an under-display photographing area and a non-under-display photographing area;
• in the under-display photographing area, an electrochromic layer is disposed on a light-emitting side of the display layer, and the electrochromic layer does not overlap any pixel area in a direction perpendicular to a plane on which the display panel is located;
• a first electrode layer is disposed on a side that is of the electrochromic layer and that faces the display layer, and a second electrode layer is disposed on a side that is of the electrochromic layer and that faces away from the display layer;
• the electrochromic layer has a first light absorption feature under action of a first voltage difference, and has a second light absorption feature under action of a second voltage difference, wherein the first light absorption feature is that the electrochromic layer has a first absorption rate for visible light and has a second absorption rate for infrared light, the second light absorption feature is that the electrochromic layer has a third absorption rate for the visible light and has a fourth absorption rate for the infrared light, the first absorption rate is greater than the third absorption rate, and the second absorption rate is less than the fourth absorption rate;
• the electrochromic layer comprises a plurality of mutually independent electrochromic parts;
• and
• the first electrode layer or the second electrode layer comprises a plurality of mutually independent color-changing electrodes, and the plurality of mutually independent electrochromic parts are in a one-to-one correspondence with the plurality of mutually independent color-changing electrodes;
• the plurality of pixel areas are arranged in a matrix comprising a plurality of pixel rows and a plurality of pixel columns;
• the plurality of electrochromic parts comprise a plurality of first electrochromic parts and a plurality of second electrochromic parts;
• each of the first electrochromic parts is located in a corresponding pixel row or a corresponding pixel column;
• and
• each of the second electrochromic parts is located outside any pixel row and any pixel column;
• a front-facing camera, wherein the front-facing camera is located in the under-display photographing area of the display panel, and the front-facing camera is located on a non-light-emitting side of the display layer;
• and
• at least one processor, wherein the at least one processor is configured to:
• when the electronic device operates in a facial recognition mode of the front-facing camera, control the electrochromic layer located in the under-display photographing area to have the first light absorption feature;
• and when the electronic device operates in a photographing mode of the front-facing camera, control at least a part of the electrochromic layer located in the under-display photographing area to have the second light absorption feature.
