Abstract: An in-cell touch screen is provided and has an array substrate, where a metal is added into and disposed in a gap between common electrode plates of the array substrate. The metal is connected with the common electrode plates, and the metal together with pixel electrodes form an electric field, such that liquid crystal molecules in an area corresponding to the gap between the common electrode plates are driven to tilt normally. Therefore, the area and other display areas have an identical display effect.

Abstract: The disclosure is related to an array substrate having a touch function and a display device. The display device comprises a plurality of touch electrodes arranged in an array, a plurality of pixel electrodes, a plurality of scan lines, and a plurality of data lines. The scan lines and the data lines intersect with each other to define pixel regions on the display device. Each of the pixel electrodes is arranged in the corresponding pixel region and electrically connects to the corresponding scan line and the corresponding data line. Each touch electrode corresponds to at least one pixel region; at least an opening portion is formed at the overlapping regions between each of the touch electrode and at least one of the scan lines and the data line to reduce the coupling capacitance. Through the above-described manner, the disclosure can effectively improve the precision of the touch screen.
