TOUCH DISPLAY PANEL, MANUFACTURING METHOD THEREOF, DRIVING METHOD THEREOF AND TOUCH DISPLAY DEVICE

摘要

A touch display panel, a manufacturing method and a driving method thereof and a touch display device are provided. The touch display panel includes an array substrate, a plurality of subpixels and a driver chip for outputting a signal to cathode layers in each subpixel group. Each subpixel includes an anode layer, a light-emitting layer and a cathode layer; one subpixel group is formed by at least two adjacent subpixels and cathode layers of the subpixels in a same subpixel group are connected. The driver chip is electrically connected with a cathode layer of at least one subpixel in the subpixel group through a conductive wire, and configured to output a common voltage signal to cathode layers in each subpixel group in a display period of one frame and to output a touch drive signal to the cathode layers in each subpixel group in a touch period of one frame.
