Patent ID: 8643595

Claim:
A method for driving an electrophoretic display that comprises an array of electrophoretic display cells, the method comprising: during an initial time duration of a driving phase, while applying a first level of voltage between a source line of at least one electrophoretic display cell in the array of electrophoretic display cells and a common electrode of the array of electrophoretic display cells, placing a switch between the source line and the at least one electrophoretic display cell in a low impedance state to allow the at least one electrophoretic display cell to be driven to a display state; during a first time duration of the driving phase that immediately follows the initial time duration, while applying the same first level of voltage between the source line and the common electrode, placing the switch between the source line and the at least one electrophoretic display cell in a high impedance state to allow the at least one electrophoretic display cell to discharge; during a second time duration of the driving phase that immediately follows the first time duration, while applying a second different level of voltage between the source line and the common electrode, maintaining the switch between the source line and the at least one electrophoretic display cell in the high impedance state.
