Abstract

The invention provides a pressure touch sensor, a display device and a drive method for the same and relates to the technical field of display, wherein wrong recognition of pressure sensing can be prevented when the display device is bent. The pressure touch sensor comprises a drive electrode, a sensing electrode as well as a piezoelectric material layer and a piezo-resistance material layers disposed between the drive electrode and the sensing electrode.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to a pressure touch sensor, a display device and a driving method thereof. Background technique [0002] With the development of information technology, the functions of mobile terminals are becoming more and more abundant, and the applications of various new technologies and new functions are also presented in different ways, and the pressure touch (3D-Touch) technology can sense the pressing force, Therefore, different functions can be realized based on different strengths and the user experience can be increased. [0003] Currently, pressure touch sensors based on the piezoelectric effect are generally used to implement multi-touch and pressure sensing functions. The pressure touch sensor includes a driving electrode and a sensing electrode, and a piezoelectric material layer located between the driving electrode and the sensing electrode; wherein the piezoelectric material layer is a...
