1. A biometric information recognition module, comprising an optical path guiding layer and a photosensitive pixel array which are arranged in sequence, wherein the optical path guiding layer comprises a plurality of optical channels, the photosensitive pixel array comprises a plurality of photosensitive pixel units, and light beams carrying biometric information pass through the optical channels respectively and then are incident on the corresponding photosensitive pixel units, wherein the optical path guiding layer comprises a central region and at least one peripheral region surrounding the central region, and the optical channels in the at least one peripheral region have included angles with a first straight line perpendicular to a surface of the photosensitive pixel array;
wherein the included angles of the plurality of optical channels in the at least one peripheral region are gradually increased in a direction from a center towards an edge of the optical path guiding layer.
