Abstract
Embodiments of the invention disclose a capacitive in-cell touch panel and a display device, in which at least a touch sense electrode (6) is disposed on a color film substrate (1), at least a touch drive electrode (5) is disposed on a TFT array substrate (2), the touch drive electrode (5) is electrically connected to a gate line (7) in the TFT array substrate (2), wherein each touch drive electrode (5) comprises a plurality of touch drive sub-electrode (51) arranged in the same row and disposed between adjacent columns of pixel units. The capacitive in-cell touch panel and the display device provided by the embodiments of the invention employ an input display signal of the gate line (7) electrically connected to the touch drive electrode (5) as the touch drive signal to realize the touch control function, thereby avoiding the addition of an IC for touch drive and reducing the production cost.
