    Abstract: The present invention discloses an in-cell touch screen, wherein a common electrode layer on the array substrate is multiplexed as self-capacitance electrodes. The common electrode layer comprises a plurality of self-capacitance electrodes arranged in array, and the common electrode layer is divided into a plurality of adjacent touch scanning areas, each touch scanning area comprises at least one row of self-capacitance electrodes. In this way, when the gate lines within one of the plurality of touch scanning areas are scanned row by row, the self-capacitance electrodes within the one touch scanning area are applied with common electrode signals, and the self-capacitance electrodes in other touch scanning areas of the plurality of touch scanning areas are applied with touch detection signals. That is to say, when display is performed in one touch scanning area, touch driving is performed in other touch scanning areas. By means of the above driving manner, the aim of simultaneous display and touch control can be achieved. It can be ensured that the various display problems and touch problems would not be caused by insufficient time due to time division driving when performing high resolution display. The present invention further discloses a display device comprising the above in-cell touch screen.
