Abstract

The invention discloses a touch method, a touch panel and a touch device, belonging to the technical field of fingerprint identification. It includes: a base substrate; a photosensitive device is formed on the base substrate, a plurality of horizontally arranged touch drive lines Tx and a plurality of vertically arranged touch sensing lines Rx, and the photosensitive device is used for living body detection. The invention effectively improves the reliability of the touch panel. The invention is used for fingerprint image collection.

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 ...
