An array substrate, manufacturing and driving methods thereof, and a display device are provided. The array substrate includes a base substrate and a plurality of gate lines and a plurality of data lines disposed on the base substrate. A plurality of pixel units distributed in an array are defined by the gate lines and the data lines; each pixel unit includes a common electrode, a pixel electrode and a thin-film transistor (TFT); a first insulating layer is disposed on one side of a layer provided with the common electrodes away from the base substrate; and a plurality of self-capacitance electrodes are disposed on one side of the first insulating layer away from the base substrate.
