Classification: CPC H  G | IPC G  H

Claim 0:
1. A display panel, comprising:
a base substrate;
a plurality of light emitting devices disposed on the base substrate;
a plurality of photosensitive devices disposed on the base substrate, wherein an orthographic projection of each photosensitive device on the base substrate is disposed at a gap of orthographic projections of adjacent light emitting devices on the base substrate; and
a plurality of light shading parts disposed on a side, facing away from the base substrate, of the light emitting devices, wherein the light shading parts are in one-to-one correspondence with the photosensitive devices, and orthographic projections of the light shading parts on the base substrate are at least partially overlapped with orthographic projections of corresponding photosensitive devices on the base substrate;
wherein an entire orthographic projection of each of the light shading parts on the base substrate is disposed within an orthographic projection of a corresponding photosensitive device on the base substrate;
wherein the base substrate comprises a plurality of fingerprint recognition regions disposed in an array; and
each of the fingerprint recognition region comprises at least two photosensitive devices, and the photosensitive devices in each of the fingerprint recognition regions are rotationally symmetrically distributed relative to a center of the fingerprint recognition regions where the photosensitive devices are disposed;
wherein a shape of the orthographic projections of the light shading parts on the base substrate is similar to a shape of the orthographic projections of the corresponding photosensitive devices on the base substrate, and centers of shapes coincide with each other;
wherein the shape of the orthographic projections of the light shading parts on the base substrate is rectangular, and a length of each side of the orthographic projections of the light shading parts on the base substrate is less than or equal to ½ of a side length of the orthographic projections of the corresponding photosensitive devices on the base substrate.
