Abstract: An in-cell touch screen and display device, which multiplex the common electrode layer as self-capacitance electrodes using self-capacitance principle, modify the pattern of the common electrode layer to segment it into a plurality of independent self-capacitance electrodes, and add on the array substrate touch control data lines that connect the respective self-capacitance electrodes to the touch control detection chip. Orthographic projections of the respective touch control data lines on the array substrate are all within areas where gaps between the pixel areas reside, so as to not affect the aperture ratio of pixel. Embodiments of the present invention modify the structure of the common electrode layer to segment it into self-capacitance electrodes, thus avoiding additional processes of manufacturing an array substrate, saving the production cost, and improving the production efficiency.

Abstract: The invention discloses a capacitive in-cell touch panel and a display device. Since at least two neighboring gate lines on a common array substrate and the gates connected with them serve as a first touch sensing electrode, at least two neighboring data lines on the common array substrate and the sources connected with them serve as a second touch sensing electrode, and there is no need to further add a new film layer on the existing array substrate, this may reduce the number of masking in the production process, decrease the thickness of the touch panel and lower the production cost; moreover, a time divisional driving mode is adopted in the touch-control time period and the display time period, which may avoid the interference between the display signal and the touch-control driving signal, and guarantee the quality of a display picture and the accuracy of the touch-control.
