Capacitive in-cell touch screen panel having a common electrode layer provided with sensing and driving electrodes

Abstract

The present invention discloses a capacitive touch module, a capacitive in-cell touch screen panel and a display device, in which an integrally connected common electrode layer in an array substrate is split to form touch sensing electrodes and touch driving electrodes which are insulated from each other; and the touch driving electrodes and the touch sensing electrodes are subjected to time-sharing drive to achieve the touch function and the display function. Moreover, each touch sensing electrode includes a plurality of touch sensing sub-electrodes; each touch driving electrode includes a plurality of touch driving sub-electrodes; and opposing sides of adjacent touch sensing sub-electrodes and touch driving sub-electrodes are broken lines. Therefore, the opposing area between the adjacent touch driving electrodes and the adjacent touch sensing electrodes can be increased, and hence the mutual capacitance between the touch driving electrodes and the touch sensing electrodes within the unit area can be increased, and consequently the sensing sensitivity of the touch screen in the touch-control process can be improved.
