Abstract: front page image
(EN)Image display apparatus (50) comprising a curved rear projection screen (54), at least one projector (52), and a curved collimating mirror (66), the curved rear projection screen (54) having a convex side, a concave side, a transparent substrate (68), a light absorbing layer (74) which is on a concave side (72) of the transparent substrate (68), and a plurality of refracting spherules (78) which are located in the light absorbing layer (74) and which are for providing apertures in the light absorbing layer (74) for directing light incident on the concave side of the rear projection screen (54) to the convex side of the rear projection screen (54), the image display apparatus (50) being such that the projector (52) projects an image at the concave side of the rear projection screen (54), and a user views the image produced on the convex side of the rear projection screen (54) via the collimating mirror (66).
(FR)L'appareil afficheur d'images (50) de l'invention comprend un écran de projection arrière courbe (54), au moins un projecteur (52), et un miroir de collimation courbe (66). L'écran de projection arrière courbe (54) possède un côté convexe, un côté concave, un substrat transparent (68), une couche photo-absorbante (74) sur le côté concave (72) du substrat transparent (68), et une pluralité de billes de réfraction (78) disposées dans la couche photo-absorbante (74), qui créent des ouvertures dans ladite couche (74) dirigeant la lumière qui frappe le côté concave de l'écran de projection arrière (54) sur le côté convexe de cet écran (54). L'appareil afficheur d'images (50) est tel que le projecteur (52) projette une image sur le côté concave de l'écran de projection arrière (54), et que l'observateur voit l'image produite sur le côté convexe du projecteur (54) via le miroir de collimation (66).
