Abstract

L'invention concerne un système destiné à attaquer de manière simplifiée des milieux électrophorétiques à l'aide de sources de tension positive et négative, les sources de tension ayant des amplitudes différentes, et un dispositif de commande qui fait passer l'électrode supérieure de façon cyclique entre les deux sources de tension et la masse tout en coordonnant l'attaque d'au moins deux électrodes d'attaque opposées à l'électrode supérieure. Le système résultant peut obtenir à peu près les mêmes états de couleur par comparaison avec la fourniture de six niveaux d'attaque indépendants et d'une masse à chaque électrode d'attaque. Ainsi, le système simplifie l'électronique requise tout en ne souffrant que d'une perte marginale en ce qui concerne la gamme de couleurs. Le système est particulièrement utile dans le cas d'un milieu électrophorétique comprenant quatre ensembles de particules différentes, par exemple, dans lequel trois des particules sont colorées et soustractives et l'une des particules diffuse la lumière.
