A display panel includes a substrate layer and an organic light-emitting display layer located above a side of the substrate layer. The organic light-emitting display layer includes a plurality of sub-pixels. The display panel also includes a light-shielding conductive layer located above a side of the substrate layer adjacent to the organic light-emitting display layer. The light-shielding conductive layer includes a plurality of small imaging apertures, and an orthographic projection of each small imaging aperture on the organic light-emitting display layer is at least partially located between adjacent sub-pixels. The display panel also includes a photosensitive device layer located below a side of the light-shielding conductive layer away from a light-emitting surface of the display panel. The display panel also includes a power signal layer electrically connected to the light-shielding conductive layer.
