Patent ID: 7002752

Claim:
A color management architecture for managing red, blue, and green primary colors from a substantially white input light, the architecture having an aggregate structure comprising: an input dichroic beam splitting element configured to split the input light into a first portion light and a second portion light, wherein the first portion light contains a first non-green primary color from the input light and wherein the second portion light contains a second non-green primary color from the input light and a green primary color from the input light, and wherein the first portion light has a path substantially perpendicular to a path of the second portion light; a first polarizing beam splitter adjacent to the input dichroic beam splitting element and configured to receive the first portion light from the input dichroic beam splitting element; a first reflective panel adjacent to the first polarizing beam splitter and configured to modulate and reflect the first portion light; a second polarizing beam splitter adjacent to the input dichroic beam splitting element and configured to receive the second portion light from the input dichroic beam splitting element and to split the second portion light into a third portion light containing the second non-green primary color and a fourth portion light containing the green primary color, wherein the third portion light has a path substantially perpendicular to a path of the fourth portion light; a second reflective panel adjacent to the second polarizing beam splitter and opposite the input dichroic beam splitting element, and configured to modulate and reflect the third portion light; a third reflective panel adjacent to the second polarizing beam splitter and located on a side of the aggregate structure not including the first or second reflective panels, wherein the third reflective panel is configured to modulate and reflect the fourth portion light; and a third polarizing beam splitter adjacent to the first and second polarizing beam splitters and configured to combine the modulated and reflected lights of the first, third, and fourth portions to form an output light, wherein the third polarizing beam splitter provides an output for the output light on a side of the aggregate structure not having the first, second, or third reflective panels.
