  • Patent number: 9645686
    Abstract: The present disclosure provides an in-cell touch panel and a display device. An entire common electrode layer on an array substrate is divided so as to form a plurality of touch driving sub-electrodes and a plurality of common sub-electrodes spaced apart from each other and arranged alternately. The touch driving sub-electrodes are electrically connected to each other via a touch driving signal line so as to form a touch driving electrode, and the common sub-electrodes are electrically connected to each other via a common electrode signal line to form a common electrode. Touch sensing electrodes are arranged on an opposite substrate and cross the touch driving electrodes.
