Abstract

Un procédé pour écrire des données sur un panneau d'affichage électrophorétique (EPID) (10) comprend le chargement des données (36, 38) pour une ligne de pixels sur les lignes de la grille (20) de l'affichage EPID. Au lieu d'écrire cette ligne unique entièrement en permettant à la rangée cathodique (18) correspondant à la tension logique "1", pendant le temps nécessaire pour provoquer la migration complète des particules pigmentées, la ligne cathodique correspondante et au moins la ligne cathodique suivante sont validées (40) pour un temps plus petit que celui nécessaire pour écrire entièrement les lignes. La grille est alors chargée avec les données correspondant à la ligne de pixels suivante et le jeu de lignes cathodiques validé est décalé d'une ligne (44), de sorte qu'au moins une ligne cathodique validée précédemment soit validée pour un temps ultérieur, la migration des particules pour l'écriture étant ainsi faite de manière plus complète aux endroits où les données de la grille sont les mêmes d'une ligne de pixels à la ligne suivante.
