    Abstract: An array substrate, an electrochromic display and a method for driving the array substrate are disclosed. A display region of the array substrate (30) comprises a plurality of sets of data lines (33) and a plurality of scan lines (36), the plurality of sets of data lines (33) and the plurality of scan lines (36) intersecting each other to divide the display region into a plurality of pixel regions, a pixel electrode (32) is disposed in each of the pixel regions and electrically connected to the data lines (33); the pixel electrode (32) comprises a central pixel electrode (32a) and a peripheral pixel electrode (32b) adjacent to and electrically isolated from the central pixel electrode (32a). When the pixel region is driven, the peripheral pixel electrode (32b) and the central pixel electrode (32a) are at opposite polarities, thereby making the electrochromic material flowing from the central pixel region (32a) corresponding to the central pixel electrode (32a) to the peripheral pixel electrode (32b) and having been changed in color to fade in color. Cross-talk between adjacent pixel regions in the electrochromic display panel can be effectively controlled, and the display effect of the electrochromic display can be improved.
