1. A display panel, having a display area and comprising:
a plurality of infrared emitting units and a plurality of infrared receiving units in the display area,
wherein the plurality of infrared emitting units are configured to emit infrared light to outside of the display panel, and the plurality of infrared receiving units are configured to receive the infrared light reflected by an object outside the display panel and output an electrical signal according to the received infrared light,
the display area comprises a plurality of pixel sub-regions arranged in a plurality of rows and a plurality of columns, and each of the plurality of pixel sub-regions comprises a plurality of sub-pixel units and one of the infrared emitting unit and the infrared receiving unit,
a size of a light emitting surface of the infrared emitting unit is larger than a size of a light emitting surface of each sub-pixel unit and a size of a receiving surface of the infrared receiving unit, and
each of the plurality of pixel sub-regions comprises a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit,
the red sub-pixel unit, the green sub-pixel unit, the blue sub-pixel unit and the infrared emitting unit or the infrared receiving unit comprised in each pixel sub-region are arranged in two columns, the red sub-pixel unit and the green sub-pixel unit are in one of the two columns, and the blue sub-pixel unit and the infrared emitting unit or the infrared receiving unit comprised in the pixel sub-region are in the other of the two columns; in each column of sub-pixel units where the blue sub-pixel units are located, every two adjacent blue sub-pixel units form a pair, and the infrared receiving unit and/or the infrared emitting unit are disposed between two adjacent pairs of blue sub-pixel units.
