Patent ID: 10031616

Abstract:
A touch feedback circuit and driving method thereof, and a touch display device are disclosed, so that the user's finger can feel feedback from a touch display, thereby improving the user experience. The touch feedback circuit comprises a deformation element, at least one control module, a control line, a first signal line and a first voltage terminal, wherein the control module is configured to output a signal provided by the first signal line to the deformation element under the control of the control line, the deformation element is configured to deform under the control of the control module and the first voltage terminal, the control line and the first signal line are used to control the deformation element corresponding to a determined touch position. The control module may also include a first to fourth control sub-module, and the touch feedback circuit may also include a first to fourth signal line and first and second voltage terminals, wherein each of the control sub-modules of the control module causes the deformation element to deform more under the control of the control line and the first to fourth signal line. Embodiments of the present disclosure further provide a method for driving the touch feedback circuit and a display device having the touch function.
