Display device.

摘要

In a bistable switching display device the occurrence of artefacts due to considerable changes of periodicity between successive grey scale stages is reduced by a suitable subdivision of the electrodes (112). To this end a drive unit (116) allocates fewer than 2<n> grey scale stages to each pixel (113) which is subdivided into n sub-pixels (113<a>, 113<b>, 113<c>). The change of periodicity will decrease when a suitable division of the surface ratios and drive sequence are chosen. <IMAGE> <IMAGE>
