Abstract: The present disclosure relates to an array substrate, a display panel, a display device and a method for driving the array substrate, which avoid the common electrode block from providing pulse signals of a same polarity for a long time, thereby reducing probability of polarization of the liquid crystal and improving display performance. The array substrate, includes a common electrode layer, the common electrode layer including at least one common electrode block, at least one touch signal line, and a driving signal module; the common electrode layer including at least one common electrode block; wherein each touch signal line is connected with a corresponding common electrode block and the driving signal module, and the driving signal module outputs at least two types of touch driving signals with opposite polarities to at least one of the at least one common electrode block at each touch stage.
