Abstract
A fingerprint identification device includes a base substrate, a plurality of photosensitive elements and an elastically deformable layer arranged at a first side of the base substrate, and a backlight source arranged at a second side of the base substrate. A light beam from the backlight source is capable of passing through a gap between two adjacent photosensitive elements toward the elastically deformable layer. The elastically deformable layer is nontransparent in the case of not being pressed by a finger, and capable of being deformed in such a manner as to correspond to valleys and ridges of the finger in the case of being pressed by the finger.
