Abstract
Fingerprint imaging module and electronic device are provided. The module includes: a light source assembly including first light source for generating first incident light and second light source for generating second incident light; a color layer including a non-opaque region corresponding to interval between the first and second light sources and adapted to transmit the first and second incident light; a sensing surface at a side of the color layer away from the light source assembly, wherein the first and second incident light form first and second reflected light on the sensing surface; an image sensor between the light source assembly and the color layer, including first and second photosensitive regions, and configured to acquire the first and second reflected light to acquire fingerprint images. Fingerprint imaging area of the image sensor and size of fingerprint images are increased, which is favorable for recognition of fingerprint images by fingerprint algorithm.
