An array substrate is provided. The array substrate includes a substrate, a pixel switch array, and a plurality of gate scanning lines and a plurality of data lines formed on the substrate, and having data signal input terminals and touch transmitting signal input terminals, the array substrate further comprising a display/touch conversion switch array and a conversion control signal line formed on the substrate, wherein the display/touch conversion switch array is coupled to at least a part of the data lines and to the conversion control signal line, and is adapted to, under control of the conversion control signal line, couple the at least a part of the data lines to the data signal input terminals in a display stage, and couple the at least a part of the data lines to the touch transmitting signal input terminals in a touch stage as touch transmitting electrodes.
