Claim Text:
1. A capacitive in-cell touch screen, comprising an upper substrate, an array substrate with a common electrode layer and a liquid crystal layer between the upper substrate and the array substrate, wherein the common electrode layer consists of a plurality of touch driving electrodes and a plurality of common electrodes, and the plurality of touch driving electrodes and the plurality of common electrodes are insulated from each other and disposed alternatively, and sides of each of the touch driving electrodes and sides of each of the common electrodes adjacent to the touch driving electrodes are both non-straight lines; in a display time for one frame of picture, the touch driving electrodes are loaded with common electrode signals and touch scanning signals in a time-division manner; the upper substrate has a plurality of touch sensing electrodes, of which orthogonal projections on the array substrate are located in areas where the common electrodes are, and the shape of the touch sensing electrodes coincide with the shape of the areas where the common electrodes are.
