Abstract

Ce système d'affichage tridimensionnel (2) comprend un panneau d'affichage (5), un élément optique, une unité d'acquisition (3) et un dispositif de commande (7). Le panneau d'affichage (5) comprend une zone active (51) configurée pour afficher une image mixte comprenant une première image et une seconde image. La zone active (51) comprend une pluralité de sous-pixels. L'élément optique est configuré pour réguler une direction de faisceau lumineux de la lumière d'image émise à partir de la zone active (51). L'unité d'acquisition (3) est configurée pour acquérir la position d'au moins un premier œil ou d'un second œil d'un utilisateur. Le dispositif de commande (7) est configuré pour afficher une image mixte dans la zone active (51). Le dispositif de commande (7) est configuré pour déterminer un premier sous-pixel et un second sous-pixel sur la base de la position de l'œil de l'utilisateur. Le dispositif de commande (7) est configuré pour afficher une troisième image sur un troisième sous-pixel qui est le premier sous-pixel et le deuxième sous-pixel.
