FINGERPRINT RECOGNITION APPARATUS, DISPLAY SCREEN, AND ELECTRONIC DEVICE

The embodiments of the present application relate to a fingerprint recognition apparatus, a display screen and an electronic device, which can reduce the thickness of the fingerprint recognition apparatus while implementing reception of multi-angle optical signals. The display screen respectively comprises, from top to bottom: a pixel layer where a light-emitting display pixel array is located and a plurality of light-blocking layers, each light-blocking layer being provided with a through-hole array, so as to form a plurality of light guide channels in different directions. The fingerprint recognition apparatus comprises: an optical sensing pixel array provided below the plurality of light-blocking layers, each light guide channel among the plurality of light guide channels corresponding to one optical sensing pixel, the plurality of light guide channels being used for transmitting, to the plurality of optical sensing pixels in the optical sensing pixel array, light signals in different directions among the
