Abstract
A biometric information recognition module and an electronic device are provided, including an optical path guiding layer and a photosensitive pixel array which are arranged in sequence. The optical path guiding layer includes a plurality of optical channels. The photosensitive pixel array includes a plurality of photosensitive pixel units, and light beams carrying biometric information pass through optical channel(s) and are then incident on corresponding photosensitive pixel unit(s), the light path guiding layer including a central region and peripheral region(s) surrounding the central region, and an included angle being formed between an optical channel in the peripheral region and a first straight line perpendicular to the surface of the photosensitive pixel array.
