Abstract

The present invention is suitable for the technical field of fingerprint identification, and provides a flexible circuit board, a terminal device and a fingerprint identification method. The flexiblecircuit board comprises: a substrate and fingerprint identification units located on the substrate and distributed in an array mode. The fingerprint identification units comprises photosensitive diodes, the projection positions of the photosensitive diodes on the substrate are located at the center area of the projection positions of four adjacent pixel sub units in the display screen, the four adjacent pixel sub units are two adjacent rows and two columns, in the distributed photosensitive diodes in the array mode, each photosensitive diode is provided with one working voltage line, each rowof photosensitive diodes are provided with scanning lines, and each photosensitive diode is provided with one data line. A fingerprint identification function is arranged on the display screen so as to increase the area of a fingerprint identification module to achieve 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 ...
