Abstract

This application is applicable to the technical field of fingerprint identification, and provides a flexible circuit board supporting full-screen fingerprint identification, a terminal device, and a fingerprint identification method. The flexible circuit board includes: a substrate, and fingerprint identification units arranged in an array on the substrate , the fingerprint identification unit includes: a photosensitive diode, the projection position of the photosensitive diode on the substrate is located in the middle area of ​​the projection positions of four adjacent pixel subunits in the display screen, and the four adjacent pixel subunits The sub-units are two adjacent rows and two columns. Among the photodiodes distributed in an array, each photodiode is provided with a working voltage line, each row of photodiodes is provided with a scanning line, and each photodiode is provided with a data line. In the present application, the fingerprint identification function can be set on the display screen, so as to increase the area of ​​the fingerprint identification module to realize the full-screen fingerprint identification function.

Description

technical field [0001] The application belongs to the technical field of fingerprint identification, and in particular relates to a flexible circuit board supporting full-screen fingerprint identification, a terminal device and a fingerprint identification method. Background technique [0002] Fingerprint recognition is a technology for identity identification by comparing the detailed feature points of different fingerprints. The fingerprints of each person are different, and the ten fingers of the same person are also obviously different, so fingerprints can be used for identification. [0003] At present, more and more mobile terminals are equipped with fingerprint identification modules, usually in non-display areas such as the home button on the front and the back. However, this setting method has the problems of small recognition area and poor human-computer interaction. Contents of the invention [0004] In view of this, the embodiments of the present application ...
