1. A display panel, having a first surface on a surface of the display panel, comprising:
a driving circuit layer, comprising a pixel driving circuit;
a light source array, on a side of the driving circuit layer close to the first surface, comprising a plurality of light sources, which are driven by the pixel driving circuit of the driving circuit layer during operation;
a sensor array, on a side of the driving circuit layer away from the first surface, comprising a plurality of sensors, wherein the plurality of sensors are configured to receive light emitted from the plurality of light sources and reflected to the plurality of sensors by a structure on a side of the first surface away from the plurality of light sources; and
a black matrix layer, on a side of the light source array close to the first surface, comprising a plurality of first light-transmitting openings and a plurality of second light-transmitting openings, wherein the plurality of first light-transmitting openings are configured to allow light, which is emitted from at least one of the plurality of light sources, emitted out from at least one of the plurality of second light-transmitting openings, and reflected by the structure, to pass through the plurality of first light-transmitting openings, to reach the plurality of sensors;
wherein the driving circuit layer comprises a plurality of light-transmitting portions, and each of the plurality of first light-transmitting openings is arranged corresponding to at least one of the plurality of light-transmitting portions for transmitting light, and a plane size of one first light-transmitting opening in a direction parallel to the surface of the display panel is smaller than a plane size of one light-transmitting portion in the direction parallel to the surface of the display panel.
