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.

Claims (7)

  1. Procédé de diminution de la période de temps d'écriture d'une trame de données d'affichage (36,38) composée d'une pluralité de lignes (20) de pixels affichables, sur un affichage électrophorétique à grande densité de lignes (10) exigeant une période de temps prédéterminée pour l'écriture complète d'une ligne, ledit procédé comprenant les étapes de:
    (a) écriture simultanée (40) d'un ensemble d'au moins deux lignes adjacentes (20) avec lesdites données d'affichage (36,38) dans une première période de temps qui est inférieure à ladite période de temps prédéterminée pour l'écriture complète d'une ligne;
    (b) décalage des éléments (44) dudit ensemble de lignes de telle sorte que ledit ensemble comporte au moins une nouvelle ligne et au moins une ligne originale;
    (c) écriture dudit ensemble de lignes décalé (40) dans une deuxième période de temps qui est inférieure à ladite période de temps prédéterminée, à la suite de ladite étape de décalage (44); et
    (d) répétition des étapes (b) et (c) jusqu'à ce que ladite trame soit complètement écrite.
  2. Procédé de la revendication 1, dans lequel la durée de chacune desdites première et deuxième périodes de temps diminue avec l'augmentation des nombres desdits éléments dans ledit ensemble de lignes.
  3. Procédé de la revendication 2, dans lequel chacune desdites première et deuxième périodes de temps approxime ladite période de temps prédéterminée divisée par le nombre d'éléments dans ledit ensemble de lignes.
  4. Procédé de la revendication 1, dans lequel lesdits pixels de ladite ligne d'origine sont écrits à une intensité de pixel, qui approxime une intensité de pixel prédéterminée d'un pixel écrit pendant ladite période de temps prédéterminée pour l'écriture complète d'une ligne, quand ladite nouvelle ligne contient des pixels d'un déplacement prédéterminé.
  5. Procédé de la revendication 4, dans lequel le procédé comporte en outre l'étape de sélection du nombre de lignes dans ledit ensemble (32).
  6. Procédé de la revendication 5, dans lequel le procédé comporte en outre l'étape de réglage de la durée de ladite période de temps (34), qui est inférieure à ladite période de temps prédéterminée pour l'écriture complète d'une ligne, quand un changement du nombre de lignes dans ledit ensemble se produit.
  7. Procédé de la revendication 6, dans lequel ledit déplacement prédéterminé est égal au déplacement d'une ligne de référence qui est située sur un bord dudit affichage (10).
