Abstract

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.
