TOUCH DISPLAY CIRCUIT AND DRIVING METHOD THEREFOR, TOUCH DISPLAY PANEL AND DISPLAY DEVICE

Title:

TOUCH DISPLAY CIRCUIT AND DRIVING METHOD THEREFOR, TOUCH DISPLAY PANEL AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/173141

Kind Code:

A1

Abstract:

A touch display circuit and a driving method therefor, a touch display panel and a display device. In a touch stage, a touch trigger module (1) supplies a signal of a trigger signal end (Input) to a pull-up node (PU); a first output module (4) supplies a signal of a first clock signal end (CK) to a touch signal output end (Output); and a reset module (3) supplies a signal of a first reference signal end (Vref1) to the pull-up node (PU), and a second output module (5) supplies a signal of a second reference signal end (Vref2) to the touch signal output end (Output), thereby implementing a touch function. In a display stage, a display switching module (2) supplies a signal of a common electrode signal end (Vcom) to the touch signal output end (Output), thereby implementing a display function. In the touch display circuit, by the mutual matching of all modules, time-sharing output of a touch signal and a common electrode signal is implemented at a touch signal output end (Output), thereby implementing the simple-structure touch display circuit, and further aiding in narrow bezel design of a touch display panel.
