Abstract

The invention discloses a touch method, a touch panel and a touch device, and belongs to the technical field of fingerprint identification. The touch panel comprises an underlying substrate. Photosensitive devices and multiple transversely arranged touch driving lines Tx and multiple longitudinally arranged touch induction lines Rx are formed on the underlying substrate. The photosensitive devices are used for living body detection. The reliability of the touch panel can be effectively enhanced. The touch panel is used for fingerprint image acquisition.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a touch method, a touch panel and a touch device. Background technique [0002] Fingerprint is a unique and invariant biological feature, which is composed of a series of ridges and valleys on the surface of the fingertip skin. The composition details of these ridges and valleys determine the uniqueness of the fingerprint pattern. People apply this feature of fingerprints to pattern recognition technology, and develop fingerprint recognition technology. In the process of fingerprint recognition, the fingerprints are usually collected by using the touch panel first, and then the collected fingerprints are compared with the fingerprints in the sample library to realize the fingerprint recognition. [0003] The existing mutual capacitive touch panel mainly includes a plurality of horizontally arranged touch driving lines Tx and a plurality of vertically arranged ...
