ABSTRACT:
The disclosed embodiments relate to a system and method for projecting video onto a screen. A video unit (10) may comprise a color wheel (14), a light source (12) configured to project light through the color wheel (14) during a spoke time, and a digital micromirror device (18) configured to reflect the projected light (30) onto a screen (26). The method may comprise the acts of shining a generally white light (28) through a region on a color wheel (14) to create a colored light (30), the region comprising two color filters, reflecting the colored light (30) off of a micromirror disposed on a digital micromirror device (18), and projecting the reflected colored light (34) onto a screen (26).
