Abstract

The invention discloses a fingerprint identification module and fingerprint identification equipment. The fingerprint identification module comprises: a transparent substrate; at least one fingerprintidentification unit which is located on one side of the transparent substrate, wherein the sensing surface of the fingerprint identification unit is arranged towards the transparent substrate, the fingerprint identification unit comprises a thin film transistor and a fingerprint sensing electrode, the thin film transistor comprises a grid electrode, a metal oxide semiconductor thin film doped with rare earth oxide and a grid insulating layer located between the grid electrode and the metal oxide semiconductor thin film, and a source electrode and a drain electrode which are respectively connected with the metal oxide semiconductor film; the source electrode or the drain electrode is electrically connected with the fingerprint sensing electrode, and the fingerprint sensing electrode, the grid electrode, the source electrode and the drain electrode are all transparent electrodes. The problems that a fingerprint sensing electrode is limited by the space size, the film layer structure ofthe fingerprint recognition module is complex, and the process difficulty of preparing the fingerprint recognition module is large are solved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification module and a fingerprint identification device. Background technique [0002] With the rapid development of display technology, display panels with a fingerprint identification function have gradually become popular. [0003] Existing fingerprint identification units usually include thin film transistors and fingerprint sensing electrodes. Since electrodes in existing thin film transistors and fingerprint sensing electrodes are generally metal electrodes, in order to avoid reducing the aperture ratio of the display panel, the fingerprint identification unit needs to be arranged on The gap area between the pixel units limits the position of the fingerprint identification unit, which increases the difficulty of the process; and the area of ​​the gap area is very small, and the fingerprint sensing electrode ca...
