Abstract

The invention discloses a fingerprint identification device, a fingerprint identification method and a display device thereof. The fingerprint identification device comprises a substrate substrate, alight-emitting layer and a touch detection layer, an encapsulation cover plate, a photosensitive layer and a control part. The control part is used for controlling the light emitting layer to form a scanning light source in the scanning region and controlling the formed scanning light source to scan in the scanning region; the light intensity distribution corresponding to the touch position is determined according to the detection signals transmitted by each detection unit, and the patterns of the fingerprint valleys and ridges are determined according to the light intensity distribution. Thelight-emitting layer can form a scanning light source at any position, moreover, the photosensitive layer can be fabricated by a semiconductor process, the fabrication process is simple, and the largesize is easy to realize. In addition, the thickness of the fingerprint identification device is reduced because the collimating film layer does not need to be provided.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification device, a fingerprint identification method and a display device thereof. Background technique [0002] With the rapid development of display technology, electronic devices with biometric identification functions have gradually entered people's lives and work. Among them, fingerprint recognition technology has become one of the most widely used and cheapest recognition technologies in biometric technology because of its uniqueness and stability. [0003] Currently, almost all of the under-screen fingerprint readers on the market are silicon-based sensors (sensors). The wafer area of ​​silicon-based sensors has a certain size. If the size needs to be increased, the cost will increase exponentially. It is difficult for the sensor to realize large-scale fingerprint recognition. Moreover, silicon-based sensors need to filter out stray...
