ABSTRACT:
A display system is disclosed that includes a light source, an integrator rod receiving a light beam from the light source and producing an integrated light beam, a beam splitting device splitting the integrated light beam into at least a first cone of light and a second cone of light, the cones of light having complementary intensity distributions, and at least a first spatial light modulator and a second spatial light modulator, wherein the first spatial light modulator is capable of selectively reflecting portions of the first cone of light in an ON direction and the second spatial light modulator is capable of selectively reflecting portions of the second cone of light in an ON direction. The display system further includes a combining device for combining the selectively reflected portions of the cones of light in the ON direction and projection optics for projecting the combined reflected cones of light.
