Electro-optic displays

A method for driving an electro-optic display, the electro-optic display comprising an electrophoretic display medium electrically coupled between at least one display pixel electrode and a first common electrode, wherein the at least one display pixel electrode is coupled to a first terminal of a storage capacitor, and wherein a second common electrode is coupled to a second terminal of the storage capacitor, the method comprising the following steps in order:

• applying a waveform sequence to the at least one display pixel electrode to provide a driving voltage to the electrophoretic display medium between the at least one display pixel electrode and the first common electrode, and connecting the storage capacitor to a first bias voltage applied to the second common electrode;
• maintaining a last frame voltage level on the at least one display pixel electrode after the completion of the applied waveform sequence by placing the at least one display pixel electrode and first common electrode in a floating state;
• and
• discharging the last frame voltage level on the at least one display pixel electrode by discharging the storage capacitor through the second common electrode, wherein during the discharging step the first bias voltage applied to the second common electrode is zero volts.
