Abstract

Il est décrit un procédé de commande d'un affichage électro-optique comportant une électrode avant, un fond de panier et un support d'affichage comprenant au moins trois particules colorées différemment, le support étant positionné entre l'électrode avant et le fond de panier. Le procédé comprend l'application d'une phase de réinitialisation et d'une phase de transition de couleur à l'affichage de telle sorte que la somme de toutes les impulsions résulte en un décalage, lequel maintient un équilibre en courant continu à travers le support d'affichage. Il est également décrit des unités de commande permettant la mise en uvre dudit procédé.
