Abstract
Telecentric afocal microlens combinations are inserted between the liquid crystal cells 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.
