Abstract: Provided are an array substrate, an electronic paper display panel and a drive method thereof and a display device. A display area includes a plurality of sub-display areas, a plurality of data lines in each sub-display area are electrically insulated from each other, corresponding data lines in different sub-display areas are electrically connected to each other, and a control signal line is configured to control display time of each sub-display area. When a control chip and a flexible circuit board are employed, only a small number of control chips and flexible circuit boards may drive the plurality of sub-display areas to display pictures.
