ABSTRACT:
A projection system and a method of forming a color image are provided. A projection system includes a light source, a color splitter which splits light emitted from the light source into colors according to a plurality of wavelength ranges, a scrolling unit which scrolls the colors split by the color splitter, a polarization converter which converts the light emitted from the light source into light having a first polarization, a color selector which converts at least some of the light having the first polarization into light having a second polarization different from the first polarization, an image combiner which transmits or reflects light transmitted by the color selector according to a polarization direction, and at least two light valves each of which receives light transmitted by the image combiner and processes the received light according to an image signal to form an image.
