Abstract
A color wheel assembly (15, 15a, 15b) for use in a display system (10) that uses a beam of source illumination to generate images with a display device. The color wheel (15) is moveable in and out of the path of the source beam so as to provide varying levels of brightness or color saturation. The color wheel (15') may also have concentric rings (41, 43) for varying saturation or color balance.
