Abstract

Un système d'écran comprend un élément écran transmettant la lumière et une première unité de commande permettant de commander la réflectivité de l'élément écran. La première unité de commande augmente la réflectivité d'une région de projection de l'élément écran, sur laquelle une image vidéo est projetée, de sorte à être supérieure à la réflectivité de l'autre région de non-projection de celui-ci.
