Patent ID: 6898019

Claim:
A single-chip spatial light modulator display system, comprising: a light source for producing a beam of light along a first light path; condensing optics in said first light path to focus said light into an integrator rod; said integrator rod collecting and focusing said light to a small spot at the surface of a rotating color filter wheel; said color wheel filtering said light into contiguous color bands, said color bands being propagated along said first light path into relay optics; said relay optics shaping and focusing said color illumination bands on to the surface of an spatial light modulator, said spatial light modulator modulating said color light and projecting said light along a second light path, said projected light being focused on to a display screen; and an electronic controller for synchronizing said color band illumination with said spatial light modulator addressing scheme for producing a highly efficient projection system while using a single spatial light modulator.
