Abstract
Provided is a fingerprint sensor, including: a substrate; a plurality of photosensitive devices disposed on the substrate; a light-emitting module disposed on a side, distal to the substrate, of the plurality of photosensitive devices; and a protective cover disposed on a side, distal to the substrate, of the light-emitting module, wherein the protective cover is provided with a plurality of conductive structures electrically connected to the light-emitting module, the plurality of conductive structures being in one-to-one correspondence with the plurality of photosensitive devices, and an orthographic projection of each conductive structure onto the substrate at least partially being overlapped with an orthographic projection of the photosensitive device corresponding to the conductive structure onto the substrate.
