Patent ID: 7466473

Claim:
A 2-channel display system comprising two spatially separate channels, simultaneously feeding two polarization coded images into a common light path out of which said images may be separated by a polarization decoding system; light of at least one light source, comprising at least 3 spectral components, which are sufficient to span a color space, feeding the two channels; a polarization split system PBS 1 with a plane of incidence P 1 POI , generating two spatially separated light beams of a different linear polarization feeding the two channels; SLMs (spatial light modulators) which are MEMSs (Micro Electro Mechanical System), at least one in each channel, characterized by modulating light via the direction of the reflection of the incident light beam; MEMSs positioned such that the axis of the incident light beam differs from the axis of the modulated “ON”-light beam, the modulated “ON” beam being reflected normal to the MEMS surface; a polarization combining system PBS 2 with a plane of incidence P 2 POI for superimposing the two spatially modulated “ON” light beams of each channel into a common “ON” light beam, said PBS 2 being spatially separated from PBS 1 ; MEMSs rotated so that the mirror deflection axes of the MEMSs of the two channels are perpendicular in their virtual projection in the superposition image.
