1. A display panel having a display region and a non-display region, comprising:
a substrate;
a driving array layer on the substrate, including first pixel circuits located in the non-display region and second pixel circuits located in the display region;
a light-emitting device layer on a side of the driving array layer away from the substrate, including first light-emitting devices located in the non-display region and second light-emitting devices located in the display region, wherein the first light-emitting devices are electrically connected with the first pixel circuits respectively and the second light-emitting devices are electrically connected with the second pixel circuits respectively; and
a photosensitive device assembly including first photosensitive devices and second photosensitive devices arranged in the driving array layer, wherein an orthographic projection of one first photosensitive device to the substrate is at least partially overlapped with an orthographic projection of one corresponding first light-emitting device to the substrate, and the second photosensitive devices are arranged in the display region.
