ELECTROPHORETIC DISPLAY AND METHOD OF OPERATING AN ELECTROPHORETIC DISPLAY

摘要

An electrophoretic display includes an electrophoretic panel and a compensation circuit. The electrophoretic panel includes a common electrode, a plurality of scan lines, a plurality of data lines, a plurality of first switches, and a plurality of pixels. Each pixel of the plurality of pixels is coupled to the common electrode and coupled to a corresponding scan line and a corresponding data line through a corresponding first switch of the plurality of first switches. The compensation circuit reduces a voltage drop between a pixel voltage of the pixel and a common voltage of the common electrode when the plurality of first switches are turned off. A capacitor of the compensation circuit is coupled between each scan line and the common electrode. A second switch of the compensation circuit is turned off to float the common electrode before the plurality of first switches are turned off.
