Abstract: Prism assemblies for projector display systems disclosed receive inputs from discrete color channels (e.g., red, green and blue channels. In one embodiment, “off state” light from the red, green, and blue DLP modulation may be reflected away from on-state light paths within the prism, tending to avoid uncontrolled scatter. In other embodiments, by keeping the colors separate for much of the prism path length, power levels may be significantly reduced at typical failure points. Light efficiency may be increased significantly when using discrete light sources like LEDs and lasers by removal of the additional red, green, and blue separation and re-combination losses.
