Display device

A display device, comprising:

• a display panel, wherein the display panel comprises a first display area, a second display area, and a third display area, wherein the third display area at least partially surrounds the first display area and the second display area, and a transmittance of the first display area and a transmittance of the second display area are greater than a transmittance of the third display area;
• a structured light-emitting end, wherein the structured light-emitting end is disposed on a backlight surface of the display panel, and the structured light-emitting end is disposed opposite to the second display area;
• and
• a structured light-receiving end, wherein the structured light-receiving end is disposed on the backlight surface of the display panel, and the structured light-receiving end is disposed opposite to the first display area;
• and
• wherein the first display area is provided with a plurality of first pixel driving circuits and a plurality of first light-emitting units, the plurality of first pixel driving circuits are connected to the plurality of first light-emitting units, and a vertical projection of each of the plurality of first pixel driving circuits on the backlight surface of the display panel overlaps a vertical projection of one of the plurality of first light-emitting units on the backlight surface of the display panel, the one of the plurality of first light-emitting units being connected to the each of the plurality of first pixel driving circuits;
• and
• wherein the second display area is provided with a plurality of second pixel driving circuits and a plurality of second light-emitting units, the plurality of second pixel driving circuits are connected to the plurality of second light-emitting units, and a light intensity of structured light emitted from the structured light-emitting end to the plurality of second pixel driving circuits is less than a light intensity of the structured light emitted into the second display area.
