An array substrate, a display panel and a display device are disclosed. The array substrate includes a base substrate and common electrode on the base substrate. The common electrode includes a plurality of sub-electrodes in an array, each being used for receiving a common voltage signal and a touch scan signal in a time-sharing manner. The array substrate further includes a common electrode wire corresponding to each sub-electrode. Each sub-electrode receives the common voltage signal through the common electrode wire, and the common electrode wire corresponding to each sub-electrode includes multiple sub-electrode wires, each being connected to the corresponding sub-electrode.
