Abstract

Selon l'invention, à l'intérieur de chaque pixel (P) d'un dispositif d'affichage (100), une pluralité de sous-pixels (R, G, B, Y) sont positionnés pour être alignés dans une direction parmi la direction de rangée et la direction de colonne. Lorsqu'une vidéo appliquée en entrée dans un mode d'affichage plan possède une première résolution, le dispositif d'affichage affiche l'équivalent d'un pixel de données de la vidéo appliquée en entrée par deux pixels qui sont adjacents dans l'autre direction parmi la direction de rangée et la direction de colonne. Lorsqu'une vidéo d'œil droit appliquée en entrée et une vidéo d'œil gauche appliquée en entrée dans un mode d'affichage stéréoscopique ont la première résolution, le dispositif d'affichage affiche l'équivalent d'un pixel de données de la vidéo d'œil droit appliquée en entrée et l'équivalent d'un pixel de données de la vidéo d'œil gauche appliquée en entrée par deux pixels qui sont adjacents dans l'autre direction parmi la direction de rangée et la direction de colonne. Lorsque la vidéo appliquée en entrée dans le mode d'affichage plan possède une seconde résolution qui est supérieure à la première résolution, le dispositif d'affichage affiche l'équivalent d'un pixel de données de la vidéo appliquée en entrée par des pluralités respectives de pixels virtuels (VP1, VP2) qui sont spécifiés par chaque pixel respectif.
