1. A projection system for projection of pixelized color images onto a display surface, the projection system comprising:
- a light source;
a color modulator configured to modulate the spectral distribution of light and pass modulated light to the display surface; and
a reflective light modulator disposed to receive light from the light source and selectively reflect the light into a first optical path that includes the color modulator and a second optical path that bypasses the color modulator.

Abstract
A projection system projects a pixelized color images onto a display surface. The projection system includes a light source, an interferometric modulator, and a reflective light modulator. The interferometric modulator is configured to modulate the wavelength of light and reflect modulated light toward the display surface. The reflective light modulator is disposed to receive light from the light source and selectively reflect the light toward the interferometric modulator and the display surface.

17. A projection system for generating color images on a display surface, the projection system comprising:
-
a color modulator including an array of color pixel elements; a light source; viewing optics; and a reflective light modulator disposed to receive light from the light source, the reflective light modulator having an array of mirror elements wherein each mirror element defines at least two light paths including a first light path wherein reflected light passes from the mirror element to the viewing optics, bypassing the color modulator and a second light path wherein reflected light passes from the light source to the color modulator before reaching the viewing optics. - View Dependent Claims (18, 19, 20, 21)

22. A method of generating an image during a frame period, the method comprising:
-
providing a projection system comprising a reflective light modulator having an array of mirror elements each receiving substantially white light from a light source, a color modulator having a plurality of color pixel elements, and a display surface; selectively controlling the reflective light modulator to define a first path wherein mirror elements pass the substantially white light to the display surface without color modulation by the color modulator and to define a second path wherein mirror elements reflect the substantially white light to the color modulator that modulates the color of the light before reflecting the light of the second path to the display surface. - View Dependent Claims (23, 24, 25, 26)
