Electrophoretic display and pixel structure therein

A method of driving an electrophoretic display is set forth for avoiding image-edge residual while sequentially displaying a first frame and a second frame. During the time of displaying the first frame, set a common voltage to be a first voltage, apply a second voltage different from the first voltage to a first pixel for writing a first data signal into the first pixel, and apply the first voltage to a second pixel adjacent to the first pixel for retaining a second data signal of the second pixel, which is different from the first data signal. During the time of displaying the second frame, set the common voltage to be the second voltage, apply the first voltage to the first pixel for writing the second data signal into the first pixel, and apply the first voltage to the second pixel for retaining the second data signal of the second pixel.
