Abstract
An electrophoretic display (EPD) including a plurality of first electrodes, a plurality of second electrodes, and a plurality of pixel units is provided. The first electrodes are arranged in parallel and configured to receive a plurality of first electrode driving signals. The second electrodes are arranged in parallel and disposed perpendicular to the first electrodes, and the second electrodes are configured to receive a plurality of second electrode scanning signals. The pixel units are respectively arranged between the first electrodes and the second electrodes as an array. Each pixel unit includes a first capacitor and a second capacitor. The first terminal of the first capacitor is coupled to the corresponding first electrode. The first terminal of the second capacitor is coupled to the second terminal of the first capacitor, and the second terminal of the second capacitor is coupled to the corresponding second electrode.
