Abstract

This application is applicable to the technical field of fingerprint identification, and provides a module supporting full-screen fingerprint identification, a terminal device, and a fingerprint identification method. The module includes: a substrate, and fingerprint identification units arranged in an array on the substrate. The fingerprint identification unit includes: photosensitive diodes, thin film transistors, the gates of the thin film transistors corresponding to the photosensitive diodes in each row of fingerprint identification units are connected to the scanning lines of this row, and the gates of the thin film transistors corresponding to the photosensitive diodes in each row of fingerprint identification units are The source electrodes are all connected to the data line of this column, and the data line is used to obtain the electrical signal generated by the photodiode when it receives the light reflected by the finger. The photodiode is also provided with a working voltage line, and the working voltage line is used In order to provide the working bias voltage for the photosensitive diode, the fingerprint identification function can be set on the display screen through the present application, so as to increase the area of ​​the fingerprint identification module to realize the full-screen fingerprint identification function.

Description

technical field [0001] The present application belongs to the technical field of fingerprint identification, and in particular relates to a module 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 terminal devices are equipped with fingerprint recognition 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 provide a m...
