Abstract

The present application provides an array substrate, a touch display panel, and a touch display panel driving method. The array substrate includes a plurality of fingerprint detection areas in the predetermined area of ​​the display area of ​​the substrate, and the substrate also includes a plurality of fingerprints. Scanning lines, the fingerprint sensing unit in the fingerprint detection area is connected to the fingerprint scanning line through the first switch tube, and each fingerprint scanning line and each scanning line are connected to the grid scanning circuit through the gate unit, so that the fingerprint detection area is in the The first time period is used for display, and the second time period is used for fingerprint detection. That is to say, in the present invention, a new fingerprint scanning line is added, and through the gating unit and the gate scanning circuit, the control of the fingerprint sensing unit in the fingerprint detection area can reuse the gate scanning circuit, thereby avoiding adding a new fingerprint control circuit, The circuit of the array substrate is simplified, and the area of ​​the non-display area does not need to be occupied.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a touch display panel and a driving method for the touch display panel. Background technique [0002] With the development of multimedia technology, portable electronic devices such as smart phones and tablet computers have become necessary tools in people's lives, in which important personal information of users is often stored. Therefore, it is necessary to set up certain identity authentication and rights management measures in the use of such products to protect the information stored in them, so as to prevent users' personal information from being accidentally leaked or stolen. [0003] Among the existing identity authentication methods, fingerprint identification (Fingerprint Identification) is a relatively advanced and widely used method. Since each person's fingerprint is unique, the fingerprint recognition authentication method is highly sec...
