Abstract: The present disclosure provides an under-screen optical fingerprint identification apparatus and a fingerprint identification method. The under-screen optical fingerprint identification apparatus comprises: a photodetection array which has a photosensitive area on which a photosensitive pixel array is provided, wherein the photosensitive pixel array comprises at least three types of pixels; and a fingerprint contact identification area located above the photodetection array and comprising a light-emitting layer and a cover layer, wherein the cover layer has a contact area, and the light-emitting layer has an identification area corresponding to the contact area, wherein the identification area comprises light-emitting units, each of which comprises a light-transmitting area and at least three light-emitting areas located therearound for emitting detection light of corresponding wavebands, wherein the detection light is reflected by an object to be identified to form signal light which passes through the filter layers and reaches corresponding three types of pixels.
