Patent

CA 2148579

Telecentric afocal microlens combinations (68, 70) are inserted between the liquid crystal cells (12, 20, 26) of an active matrix liquid crystal subtractive color display to retain light within a projection of each liquid crystal pixel as the light propagates through the system. A resulting reduction in light losses at the edge of each pixel significantly improves the output brightness and resolution.

Des combinaisons télécentriques de microlentilles afocales (68, 70) sont insérées entre les cellules à cristaux liquides (12, 20, 26) d'un affichage couleur soustractif à cristaux liquides et à matrice active, de façon à retenir la lumière à l'intérieur d'une projection de chaque pixel de cristaux liquides simultanément à la propagation de la lumière à travers le système. La diminution obtenue des pertes lumineuses au niveau du bord de chaque pixel améliore considérablement la brillance de sortie et la résolution.
