Electrophoretic display device and driving method therefor

摘要

An electrophoretic display has at least one pixel ( 18 ) which comprises electrophoretic material ( 8, 9 ), a first electrode ( 6 ) and a second electrode ( 5 ). An addressing circuit ( 16, 10 ) addresses the at least one pixel ( 18 ) by applying between the first electrode ( 6 ) and the second electrode ( 5 ): (i) a drive pulse (Vdr) with a level in accordance with an optical state to be reached by the at least one pixel ( 18 ), and (ii) a series of shaking pulses (SP) which have an energy content depending on an optical state of the at least one pixel ( 18 ).
