Zusammenfassung:	A system for driving a moving particle display device, such as an electrophoretic display device, is disclosed. The display device comprises first and second cells (30) that are set to target optical states to give the cells' their target optical appearances. The first and second cells are driven differently from one another, such that errors in the first cell's target optical state occur in the opposite direction to errors in the second cell's target optical state. Hence, when the cells are viewed from a distance by a viewer of the display, the light from the first and second cells mixes together, and the optical state errors appear to compensate or cancel one another out.
