(54) FINGERPRINT RECOGNITION APPARATUS AND ELECTRONIC DEVICE


(57) Embodiments of the present application disclose a fingerprint identification apparatus and an electronic device. The fingerprint identification apparatus includes a plurality of fingerprint identification units distributed in an array, and each of the plurality of fingerprint identification units includes: a plurality of pixel units; a micro lens disposed above the plurality of pixel pixels; and a plurality of light shielding layers disposed between the micro lens and the plurality of pixel units, where each of the plurality of light shielding layers is provided with light passing holes corresponding to the plurality of pixel units so as to from a plurality of light directing channels in one-to-one correspondence with the plurality of pixel units; where the plurality of light shielding layers include a bottom light shielding layer and an intermediate light shielding layer, the intermediate light shielding layer includes a light shielding layer other than the bottom light shielding layer, a light passing aperture D2 of a light passing region formed by light passing holes in the intermediate light shielding layer that are corresponding to the plurality of pixel units and a maximum aperture CA of the micro lens satisfy 0.3≤D2/CA≤1.3, and D2 is a distance between two farthest points in the light passing region on a plane where the intermediate light shielding layer is located.
