Claim:
1. A self-capacitance in-cell touch screen comprising an array substrate which has a glass substrate, thin film transistors disposed on the glass substrate, and pixel electrodes electrically connected with the thin film transistors, a planarizing layer being disposed between the pixel electrodes and the thin film transistors, wherein a transparent touch control sensing electrode, a first insulation layer, a second insulation layer, and a metal connection line are disposed on the planarizing layer in sequence, and the metal connection line is electrically connected to the touch control sensing electrode through via holes disposed in the first insulation layer and the second insulation layer; wherein the first insulation layer extends to a position between the planarizing layer and the pixel electrode, and the second insulation layer extends to be located on the pixel electrodes which are electrically connected to the thin film transistors through a via hole disposed in the first insulation layer and the planarizing layer; and wherein the touch control sensing electrode is further configured as a common electrode to transfer a common voltage and a touch scan signal by time-sharing during a period of displaying one frame image.
