Abstract
Description
technical field
[0001] The present 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 functions are also presented in different ways. The pressure touch (3D-Touch) technology can sense the pressing force, Therefore, different functions can be realized based on different strengths, thereby increasing user experience.
[0003] At present, pressure touch sensors based on piezoelectric effects are generally used to realize multi-touch and pressure sensing functions. The pressure touch sensor includes a driving electrode and a sensing electrode, and a piezoelectric material layer between the driving electrode and the sensing electrode; wherein the piezoelectric material layer is an insulato...
