| description | The embodiment of the invention relates to a fingerprint identification device, a display screen and electronic equipment, in which the thickness of the fingerprint identification device is reduced while multi-angle optical signals are received. The display screen comprises a pixel layer where a light-emitting display pixel array is located and a plurality of light shielding layers from top to bottom, and each light shielding layer is provided with a through hole array to form a plurality of light guide channels in different directions. The fingerprint identification device comprises: an optical sensing pixel array arranged below the plurality of light shielding layers, each light guide channel in the plurality of light guide channels corresponds to one optical sensing pixel; the pluralityof light guide channels are used for transmitting light signals in different directions in return light signals passing through a finger to the plurality of optical sensing pixels in the optical sensing pixel array, each opt |
