Abstract
Embodiments of the present invention disclose a capacitive in-cell touch panel, a driving method thereof and a display device. Touch sensing electrodes extended along the row direction of pixel units are arranged on a color filter substrate; a thin-film transistor (TFT) array substrate adopts a dual gate structure, that is, two gate signal lines are disposed between every two adjacent rows of pixel units; every two adjacent columns of pixel units are taken as a group of pixel unit columns and share a data signal line disposed between the two pixel unit columns, so that the positions of a part of data signal lines can be saved; and touch driving electrodes for achieving the touch function are arranged at the saved positions of the data signal lines.
