Patent ID: 7554623

Claim:
An apparatus comprising: an illumination module having a first solid-state light source adapted to produce a first illumination bundle and a second solid-state light source to produce a second illumination bundle; and an optical assembly adapted to receive the first and the second illumination bundles over a first range of incident angles and a second range of incident angles, respectively, the first range of incident angles being different from the second range of incident angles, to present a first portion of the first illumination bundle, and a first portion of the second illumination bundle, each having a first polarization state, to first and second subpixels, respectively, to rotate a second portion of the first illumination bundle and a second portion of the second illumination bundle, each having a second polarization state, to the first polarization state, and to present the second portions of the first and second illumination bundles to the first and second subpixels, respectively, wherein the optical assembly is adapted to present the first and second portions of the first illumination bundle in a manner to complement a rectangular aspect ratio of the first subpixel by causing the first portion to be incident upon a first section of the first subpixel and causing the second portion to be incident upon a second section of the first subpixel, the first section and the second section being at least partially non-overlapping sections distributed along a major axis of the first subpixel, and to present the first and second portions of the second illumination bundle in a manner complement a rectangular aspect ratio of the second subpixel.
