Abstract

L'invention concerne un système de génération d'images. Une matrice d'affichage comporte une pluralité d'éléments d'affichage qui peut comprendre des cristaux liquides. Chaque élément d'affichage comprend un pixel. Une pluralité de circuits d'affichage est connectée de manière électrique à un élément d'affichage. Une pluralité de cellules de mémoire est associée à chacun desdits circuits, ou forme une partie du circuit, ainsi qu'à un sélecteur continuellement connecté de manière électrique à plus d'une cellule de mémoire de ladite pluralité de cellules, le sélecteur transmettant au pixel les données provenant d'une cellule de mémoire à la fois. Des circuits de commande périphériques commandent de préférence des opérations de lecture et d'écriture vers les cellules de mémoire. L'invention concerne également un mécanisme émetteur de lumière, qui peut être un mécanisme présent à chaque pixel, un mécanisme modulateur de lumière, présent à chaque pixel, et/ou une source d'éclairage pour éclairer les pixels. Un circuit logique supprime le papillotement de l'image au moyen de couleur binaire équilibrée. L'invention concerne également un procédé de génération d'image. Un élément d'affichage d'un affichage est commuté sur zéro volt pendant une première période. Une première tension est appliquée à une électrode de l'élément d'affichage pendant une seconde période. Une seconde tension est appliquée à une contre-électrode dudit élément d'affichage pendant une troisième période, de sorte qu'aucune tension de réseau ne soit appliquée à l'élément d'affichage. Une impulsion d'éclairage est appliquée au pixel pour éclairer l'élément d'affichage pendant un nombre prédéterminé d'unités de temps, lesdites unités de temps pouvant être exprimées en fractions de millisecondes etc.
