Abstract
An electrophoretic display and a driving method thereof are provided. The electrophoretic display includes a display panel and a source driver. The display panel includes at least one pixel unit. The pixel unit is coupled to a pixel electrode and a common electrode. The source driver is coupled to the display panel. When the source driver provides a first driving voltage to the pixel electrode having a second driving voltage, the source driver provides a ground voltage to the pixel electrode, and then the source driver provides first driving voltage to the pixel electrode. The ground voltage is between the first driving voltage and the second driving voltage. Thereby, damage property of elements may be reduced.
