Abstract
A fingerprint identification module collimating light reflected by fingertip skin patterns defines a fingerprint identification area and a peripheral area, for identifying fingerprints. The module includes a first light-shielding layer, optical sensors, a second light-shielding layer, a supporting portion, and a gap portion. The first and second light-shielding layers each define through holes (first and second through holes). Each second through hole exposes one optical sensor and is aligned with one first through hole. The supporting portion in the peripheral area bonds the first and second substrates, maintaining a certain distance between the first and second light-shielding layers. The gap portion is in the fingerprint identification area. Light reflected by a fingerprint is collimated by the first through holes, the gap portion, and the second through holes and then received as optical signals by the sensors to realize fingerprint imaging.
