Electrophoretic display and structure thereof for reducing coupling effect therein

摘要

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.

1. An electrophoretic display (EPD), comprising:
a plurality of first electrodes, arranged in parallel, and configured to receive a plurality of first electrode driving signals; a plurality of second electrodes, arranged in parallel and perpendicular to the first electrodes, and configured to receive a plurality of second electrode scanning signals; and a plurality of pixel units, respectively arranged between the first electrodes and the second electrodes to an array, wherein each of the pixel units comprises:
a first capacitor, having a first terminal and a second terminal, wherein the first terminal is coupled to the first electrode corresponding to each of the pixel units; anda second capacitor, having a first terminal and a second terminal, wherein the first terminal of the second capacitor is only direct electrically connected to the second terminal of the first capacitor, and the second terminal of the second capacitor is coupled to the second electrode corresponding to each of the pixel units, wherein the first terminal of the first capacitor and the second terminal of the second capacitor are separate terminals,wherein the first capacitor and the second capacitor are coupled in series, a capacitance of the first capacitor is smaller than a capacitance of the second capacitor, and the second capacitor is formed of a fluid medium layer in the EPD.
