Problems solved by technology

[0003] When the existing commonly used ultrasonic fingerprint recognition is set in the display panel, it is mainly realized by an external structure. Among them, in the touch panel with an external structure, optical glue (Optically Clear Adhesive, OCA) is required to bond the polarizer and the cover plate. ) for bonding, and the touch screen and the light-emitting structure also need to be bonded with optical glue, thereby increasing the thickness of the touch display panel and increasing the bending radius of the touch display panel when making foldable products

Abstract

The invention discloses a touch display panel, its driving method, and a touch display device, which are used to omit the polarizer in the touch display panel, thereby reducing the thickness of the touch display panel and the bending radius of the touch display panel . The touch display panel includes: a base substrate, a touch structure disposed on the base substrate; the touch structure includes a first electrode layer and a second electrode layer arranged in different layers, and a touch control structure disposed on the base substrate Transparent piezoelectric units arranged in an array between the first electrode layer and the second electrode layer; wherein the first electrode layer and / or the second electrode layer include electrode units arranged in an array, and The transparent piezoelectric unit has a light filtering effect.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display panel, a driving method thereof, and a touch display device. Background technique [0002] At present, fingerprint recognition technology is developing rapidly, and it is transitioning to the product end. Fingerprint recognition technology includes: ultrasonic recognition, optical recognition or recognition through capacitance. [0003] When the existing commonly used ultrasonic fingerprint recognition is set in the display panel, it is mainly realized by an external structure. Among them, in the touch panel with an external structure, optical glue (Optically Clear Adhesive, OCA) is required to bond the polarizer and the cover plate. ) for bonding, and the touch screen and the light-emitting structure also need to be bonded with optical glue, thereby increasing the thickness of the touch display panel and increasing the bending radius of the touch display p...
