Abstract

Dispositif d'affichage par voie d'électrophorèse qui est muni d'une électrode frontale transparente, d'au moins une électrode arrière segmentée, d'une couche isolante couvrant ladite électrode arriere, ainsi que d'une électrode à mailles qui affecte la forme de l'électrode segmentée et est élaborée sur la couche isolante. La durée de commutation entre l'électrode arrière et l'électrode à mailles est réduite fortement comme relativement au dispositif d'affichage connu. La suspension est par exemple formée par un liquide clair dans lequel des particules de pigment chargé sont mises en suspension. Application aux dispositifs de reproduction.
