1. A projection system, comprising:
- an integrator with an output end;
a matrix of output windows at the output end of the integrator;
a pattern of red, green and blue monochromatic filters on the matrix of output windows passing a matrix of red, green, and blue monochromatic pixels of light;
an imager for modulating the matrix of monochromatic pixels of light; and
a light shifting device for shifting the matrix of monochromatic pixels of light to temporally form a pattern of overlying monochromatic pixels of light of different colors, viewable as a color image.

Abstract
A projection system including an integrator with an output end having a matrix of output windows therein. A pattern of red, green and blue monochromatic filters are disposed on the output windows passing a matrix of red, green, and blue monochromatic pixels of light. An imager modulates the pixels of monochromatic light A light shift device shifts the matrix of monochromatic pixels of light to temporally form a pattern of overlying pixels of light of different colors, viewable as a color image.

11. A projection system comprising:
-
a light source; an integrator being optically coupled to the light source and having an array of windows at an output end to form an array of discrete pixels of light, wherein each window of the integrator is covered by a filter to project pixels of differing monochromatic light; a micro-display being optically coupled to the array of discrete pixels of light for modulating each pixel of light incident on a corresponding position of the micro-display; and a pixel shift wheel optically coupled to a light output of the micro-display for temporally shifting the light output and is configured to successively shift different color pixels onto the same position. - View Dependent Claims (12, 13)
