Abstract

L'invention concerne un système d'affichage d'images tridimensionnelles (10) qui comporte un afficheur (12) et une paire de lunettes à obturateurs (14). L'afficheur (12) est conçu pour afficher un signal d'image d'œil gauche, un signal d'image d'œil droit, ainsi qu'un signal d'instruction (C). Les lunettes à obturateurs (14) comportent une partie œil gauche (142), une partie œil droit (144), et un élément captant la lumière (146). Ledit élément captant la lumière (146) capte le signal d'instruction (C), et commande la partie œil gauche (142) et la partie œil droit (144) des lunettes à obturateurs pour émettre ou bloquer la lumière, sur la base du signal d'instruction (C). Ainsi, on peut améliorer l'effet d'affichage par le système d'affichage d'images tridimensionnelles.
