Abstract

The invention discloses an array substrate, a driving method therefor, a display panel, and a display device. In the array substrate, the driving mode of the array substrate can be time-division driving because the orthographic projection of each subpixel unit on the substrate and the orthographic projection of each fingerprint recognition unit on the substrate are arranged in a matrix. The driving mode is a mode that the fingerprint recognition units are reused as subpixel units for displaying pictures in a display time period and only the fingerprint recognition units in each row are loaded with fingerprint recognition signals when all subpixel units are closed, so as to detect current signals, transmitted on each fingerprint recognition reading line, coupled to fingerprint recognition signals of the fingerprint recognition signals in the row, and complete the recognition of fingerprint lines. Therefore, a problem of mutual interference between the fingerprint recognition signals and the display signals is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a driving method thereof, a display panel and a display device. Background technique [0002] Fingerprints are inherently unique and invariable features that can be distinguished from others. It consists of a series of ridges and valleys on the skin surface of the fingertips. The details of the composition of these ridges and valleys determine the uniqueness of the fingerprint pattern. The fingerprint identification element developed from it was used for personal identity verification earlier, and the capacitive fingerprint identification element is widely used and well known at present. [0003] Applying the existing capacitive fingerprint identification element to the display panel is generally realized by directly adding additional fingerprint identification electrodes and signal lines electrically connected to the display panel. Its working proce...
