Title: TOUCH DISPLAY PANEL, DRIVER CIRCUIT OF TOUCH DISPLAY PANEL, AND DRIVE METHOD
Abstract:
Provided are a touch display panel, a driver circuit of a touch display panel, and a drive method; the touch display panel comprises a common electrode layer (3) used for display, the common electrode layer (3) also being used as a touch detection electrode layer (3) for detecting touch; the common electrode layer (3) is divided into a plurality of regions, each of the regions corresponds to an independent common voltage. When the touch display panel performs display scanning, each of the regions of the common electrode layer (3) is driven by a separate independent common voltage, and each of the regions provides, according to the charging conditions of its capacitor, a corresponding common voltage; thus the situation of optimal common voltages being different due to differences in the charging conditions of the capacitor that result from retarded scanning is improved, increasing display quality.
