Abstract
A display system for providing multicolor light patches for illuminating display images includes at least one light source for providing a light, at least one light pipe having an input end and an output end for allowing the light to enter via the input end and exit via the output end, and at least one color interface coupled to the output end of the at least one light pipe. The at least one color interface includes at least one color material and each color material has a different color characteristic. Light passing through the color material creates an illumination patch associated with the color characteristic of the color material. The display system further includes an optical device coupled with the at least one color interface and configured to receive the illumination patches, combine the illumination patches, and cause a combined illumination patch to be projected as a display image.
