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, a driving method thereof and a touch display device for omitting a polaroid in a touch display panel so as to decrease the thickness of the touch displaypanel and the bent radius of the touch display panel. The touch display panel comprises a substrate and a touch structure arranged on the substrate; the touch structure comprises a first electrode layer and a second electrode layer which are arranged in different layers, and transparent piezoelectric units arrayed and distributed between the first electrode layer and the second electrode layer; the first electrode layer and / or the second electrode layer include / includes electrode units arrayed and distributed, and the transparent piezoelectric units have the filtering effects.

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...
