Title
(EN) DUAL STACKED PANEL DISPLAY
(FR) AFFICHAGE FORME DE DEUX PANNEAUX EMPILES
Abstract
(EN)
A system for displaying three-dimensional images and video utilizing flat panel technology, such as liquid crystal technology, wherein the left and right images are separated by polarization and the user wears polarized glasses (114) to view the display. A first display (106), which may be any display technology, is used to generated an intensity modulated images. The second display (110) is used to modulate the polarization of the intensity modulated image. A light spreading device (112) is used to spread the light to minimize Moire effects resulting from the use of two displays. In one embodiment, the light spreader is a diffuser (112). In another embodiment, the light spreader is a micro lens array.

L'invention concerne un système pour afficher des images tridimensionnelles et des données vidéo au moyen de la technologie des écrans plats, telle que la technologie des cristaux liquides. Selon l'invention, les images gauche et droite sont séparées par polarisation, et l'utilisateur porte des lunettes polarisées pour visualiser l'affichage. Un premier affichage pouvant résulter d'une technologie d'affichage quelconque est utilisé pour générer une image à intensité modulée. Le deuxième affichage est utilisé pour moduler la polarisation de l'image à intensité modulée. Un dispositif de diffusion de lumière sert à diffuser la lumière afin de réduire au maximum les effets de moiré liés à l'utilisation de deux affichages. Dans un mode de réalisation de cette invention, le dispositif de diffusion de lumière se présente sous la forme d'un diffuseur. Dans un autre mode de réalisation, le dispositif de diffusion de lumière se présente sous la forme d'un réseau de microlentilles.
