Abstract

Chaque image couleur est décomposée en au moins une série d'au moins trois images primaires successives de couleurs primaires différentes, qui sont affichées successivement par modulation de la durée d'activation des pixels d'un imageur ; selon l'invention, on resserre la distribution des phases d'activation des pixels dans les trois sous-trames successives : on décale les périodes d'activation des pixels de la première image primaire vers la fin de la sous-trame de cette première image, et, lors de la sous-trame de la troisième image primaire, on décale les périodes d'activation des pixels de cette troisième image primaire vers le début de la sous-trame de cette troisième image. On diminue ainsi avantageusement les défauts de rupture de couleur.
