Abstract

L'invention concerne une matrice d'affichage destinée à former une image composite à partir d'une série de sous-images. En règle générale, la matrice d'affichage comprend plusieurs éléments d'affichage, chacun desquels comprenant un pixel, et un circuit d'affichage connecté électriquement au pixel. Une source d'éclairage éclaire chaque pixel. Une logique commande l'intensité de chaque pixel en utilisant une forme d'onde commandée numériquement pour commander une durée pendant laquelle l'éclairage peut traverser le cristal liquide des éléments d'affichage. L'invention concerne également un procédé de commande de l'affichage numérique. Chaque chronomètre de pixels, parmi un ensemble, est paramétré avec une valeur d'intensité, les chronomètres de pixels étant associés à des pixels d'un affichage. Les pixels de l'affichage sont paramétrés dans un premier état. Chaque chronomètre est initialisé. L'éclairage est appliqué à l'affichage. Chaque pixel est commuté dans un second état au terme de la durée de chronométrage. L'opération est répétée un nombre de fois prédéterminé pour générer une image. Dans un mode de réalisation, l'invention concerne également un procédé de production d'une image en niveaux de gris sur un affichage numérique. Des valeurs d'intensité pour chaque pixel sont stockées dans des mémoires de pixel toutes associées aux pixels individuels d'un affichage. Chacun des pixels est paramétré dans un premier état. Un premier niveau d'intensité est diffusé aux pixels. Le premier niveau d'intensité est analysé avec les valeurs d'intensité stockées dans les mémoires de pixel. Les pixels dont la valeur d'intensité associée correspond au premier niveau d'intensité sont commutés dans un second état. L'éclairage est appliqué à l'affichage. On laisse ensuite s'écouler une période de temps prédéterminée. Une valeur d'intensité suivante est alors diffusée aux pixels et le niveau d'intensité suivant est analysé avec les valeurs d'intensité stockées dans les mémoires de pixel. Les pixels dont la valeur d'intensité associée correspond au niveau d'intensité suivant sont commutés dans le second état. Les deux étapes finales du procédé sont répétées pour chaque niveau d'intensité souhaitée.
