An electronic paper includes a base substrate, and a plurality of pixel units each including a pixel driver circuit and a display unit. The display unit includes a first electrode, an electronic ink layer, and a second electrode arranged in a stack. The electronic ink layer includes a plurality of microcapsules or a plurality of microcups. Pixel driver circuits of pixel units in a same column are connected to a same data line. The plurality of pixel units are divided into a plurality of pixel unit groups each including multiple pixel units arranged side by side in a row direction and/or a column direction. The electronic paper includes a plurality of first connection pads on the base substrate. Data lines connected to at least two columns of pixel driver circuits connected to different gate lines are connected to a same first connection pad.
