Abstract

La présente invention concerne un dispositif d'affichage stéréoscopique qui comprend un dispositif d'affichage à écran plat comportant un substrat (501) de transistor à couches minces (TFT) ainsi qu'un substrat (502) de film coloré (CF) situés en regard l'un de l'autre. Le substrat TFT (501) et le substrat CF (502) incluent respectivement une pluralité de rangées de sous-pixels (505, 1005) disposées de manière à leur correspondre. Chaque rangée de sous-pixels (505, 1005) sur le substrat CF (502) est de la même couleur, et une première partie d'ombrage se trouve entre deux sous-pixels (505, 1005) adjacents. Chaque sous-pixel (505, 1005) sur le substrat TFT (501) est commandé par un TFT (506), et chaque sous-pixel (505, 1005) sur le substrat CF (502) ou chaque sous-pixel (505, 1005) sur le substrat TFT (501) sont dotés de secondes parties d'ombrage (510, 802, 1006). Chaque sous-pixel (505, 1005) sur le substrat CF (502) ou chaque sous-pixel (505, 1005) sur le substrat TFT (501) sont divisés en m parties par les secondes parties d'ombrage (510, 802, 1006), m étant un nombre entier supérieur à 1. Chaque sous-pixel (505, 1005) est divisé en une pluralité de parties à l'aide des secondes parties d'ombrage (510, 802, 1006), et l'espacement des franges de moiré est efficacement réduit, ce qui permet de résoudre le problème d'interférence dans les franges de moiré.
