An array substrate including a display area and a peripheral area, wherein: the display area includes a plurality of thin film transistors provided on a base substrate, first transparent electrodes electrically connected with drain electrodes of the thin film transistors, and second transparent electrodes, characterized in that: the array substrate further includes a transparent insulation layer that contacts the second transparent electrodes; in the case where a voltage applied on the transparent insulation layer is larger than a predetermined voltage, the transparent insulation layer becomes a conductor, and in the case where the voltage applied on the transparent insulation layer is less than the predetermined voltage, the transparent insulation layer becomes an insulator; the second transparent electrodes include first sub-electrodes arranged into a plurality of rows in a first direction, and second sub-electrodes arranged into a plurality of rows in a second direction; the first sub-electrodes in different rows are insulated from each other, the second sub-electrodes in different rows are insulated from each other, and the first sub-electrodes and the second sub-electrodes are insulated from each other; the first direction is intersected with the second direction; common electrode signals are applied simultaneously on the first sub-electrodes and the second sub-electrodes of the second transparent electrodes during a display period, and driving signals and sensing signals are applied on the first sub-electrodes and the second sub-electrodes during a touch period; and when a certain first sub-electrode or second sub-electrode of the transparent electrodes has charges accumulated thereon, and the voltage generated by the charges is larger than the predetermined voltage, this voltage is applied on the transparent insulation layer so that the transparent insulation layer renders conductivity. the display area includes a plurality of thin film transistors provided on a base substrate, first transparent electrodes electrically connected with drain electrodes of the thin film transistors, and second transparent electrodes, characterized in that: the array substrate further includes a transparent insulation layer that contacts the second transparent electrodes;
