Abstract
The embodiments of the disclosure provides a capacitive in-cell touch panel, a driving method thereof and a display apparatus, wherein touch sensing electrodes are set on a color filter substrate, a common electrode layer connected as a whole plane on a TFT array substrate is divided into strips to be used as touch driving electrodes; touch driving signal lines are set in a display area of the touch panel by adopting a dual gate structure, which is helpful for a narrow frame design of the touch panel; each of the touch driving electrodes is electrically connected to at least one touch driving signal line and is supplied with a driving signal by a plurality of touch driving signal lines simultaneously, such that transmission efficiency of the driving signal can be improved to the maximum extent and delay of the driving signal can be reduced.
