Abstract
An in-cell touch display device comprises a plurality of pixel structures, a display scanning circuit, a touch scanning circuit, and a control module. The pixel structures are applied to display an image and include a plurality of display scanning lines and a plurality of common electrodes. The display scanning circuit is coupled with the display scanning lines for actuating the pixel structures to display the image. The touch scanning circuit is coupled with the common electrodes so as to receive a touch signal by scanning the common electrodes. The control module is coupled with the display scanning circuit and the touch scanning circuit to receive and process the touch signal for executing the touch step. The display scanning circuit and the touch scanning circuit are integrated on the same substrate to reduce the thickness of the touch display device without affecting the touch effect.
