1. A capacitive in-cell touch panel comprising an array substrate on which a gate line, a data line and a common electrode layer are disposed, wherein,the common electrode layer comprises a plurality of touch drive electrode elements and a plurality of touch sense electrode elements insulated from each other;

  • the touch drive electrode elements comprise a plurality of touch drive sub-electrodes, the touch sense electrode elements comprise a plurality of touch sense sub-electrodes;

    wherein the touch drive sub-electrodes or the touch sense sub-electrodes are bridged to each other along a data line direction, and the touch sense sub-electrodes or the touch drive sub-electrodes are directly connected with each other along a gate line direction;

    or, the touch drive sub-electrodes or the touch sense sub-electrodes are bridged to each other along the gate line direction, and the touch sense sub-electrodes or the touch drive sub-electrodes are directly connected along the data line direction;

    wherein at least one gate line functions as a touch scan line during a touch period for applying a touch scan signal to the touch drive electrode elements, when the touch drive sub-electrodes are directly connected with each other along the gate line direction and the touch sense sub-electrodes are bridged to each other along the data line direction.
