Abstract

The invention discloses a fingerprint identification member, an identification method, a display member and a display device. The fingerprint member comprises a plurality of finger print identification units which are arranged in a matrix, finger identification scanning lines which are in one-to-one correspondence with the finger identification units in each line, and fingerprint identification reading lines which are in one-to-one correspondence with each column of the fingerprint identification units; each fingerprint identification unit comprises a first film transistor and a second film transistor; the light current generated by the first film transistor in each fingerprint identification unit corresponding to the fingerprint identification scanning line is transmitted to the fingerprint identification reading line through the second film transistor in the fingerprint identification unit by loading scanning signals on various fingerprint identification scanning lines to control the opening of the second film transistor in the corresponding fingerprint identification unit; the fingerprint can be identified through detecting the light current on the fingerprint identification reading line without arranging the signal lines which are in one-to-one correspondence with the various first film transistors. The invention reduces the wire arranging of the fingerprint identification unit and simplifies the structure of the finger identification member.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a fingerprint identification element, an identification method thereof, a display device and a display device. Background technique [0002] Fingerprints are invariable features of the human body that are inherently unique and distinguishable from others. It consists of a series of ridges and valleys on the surface of the skin on the fingertips. The compositional details of these ridges and valleys usually include details such as ridge forks, ridge ends, arches, tent-like arches, left-handed, right-handed, spiral or double-handed, etc., which determine the uniqueness of the fingerprint pattern. The fingerprint identification element developed from it was used for personal identity verification earlier, and currently widely used and well-known are: photosensitive fingerprint identification element and capacitive fingerprint identification element. [0003] In the existing photo...
