Abstract
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).
