Abstract

The embodiment of the invention provides a touch structure and a touch display device, and relates to the technical field of touch screens. The problems that a touch display panel with the pressure touch function is large in thickness and not beneficial to lightening and thinning of a touch display panel are solved. The touch structure comprises a compressed plate, a piezoelectric element arranged below the compressed plate and a processing chip; the piezoelectric element comprises a piezoelectric material part and electrodes making contact with the two ends of the piezoelectric material part in the polarization direction of the piezoelectric material part, pressure applied to the compressed plate can be transmitted to the piezoelectric material part, the polarization direction of the piezoelectric material part is parallel to the compressed surface of the compressed plate, and the processing chip is connected with the two electrodes of the piezoelectric element through wires and used for obtaining the compression degree of the piezoelectric material part according to a potential difference between the electrodes of the piezoelectric element.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a touch structure and a touch display device. Background technique [0002] With the application of force touch, a new type of touch mode, in portable mobile smart devices, the industry has also set off an upsurge of research on force touch (Force Touch). The pressure touch technology can sense the pressing pressure of the touch, so as to give feedback on the actions of tapping, tapping, and pressing again. In this way, the touch interaction can be extended from the "time" dimension of long press to the "strength" dimension of heavy pressure, opening up a new space for human-computer interaction. [0003] Existing pressure touch solutions measure the pressing force of the touch through the principle of capacitance. Specifically, a pressure sensing layer, an insulating layer and a reference layer arranged in sequence are formed in the touch display panel. When the...
