Abstract
A color liquid crystal display projector has a light source with a radiating element (e.g., arc or incandescent) and a liquid crystal display (LCD). The LCD includes an array of multiple picture elements or pixels that each have separate color component sub-pixels (e.g., red, green and blue). Multiple differently inclined dichroic mirrors angularly separate the light into light beams of different color components. An integrating lens array relay system has a pair of planar lens arrays that form multiple spatially separated images of the angularly-color separated light components. An array of microlenses is positioned adjacent to the LCD. Each microlens is in one-to-one alignment with LCD pixels along at least one dimension and images the spatially separated images upon multiple pixels in at least the one dimension.
