I claim:
1. A projection display comprising:
a dichroic beam splitter adapted to separate white light of a first polarization state into a first color set that includes first and second color components, and a second color set that includes a third color component, such that the first color set traverses an optical path different from that of the second color set;
a first light polarization selector for receiving the first color set from said dichroic beam splitter, said first light polarization selector changing the polarization state of the first color component of the first color set into a second polarization state;
a first polarized beam splitter prism for receiving the first color set from said first light polarization selector;
a first light modulator disposed adjacent to a first surface of said first polarized beam splitter prism;
a second light modulator disposed adjacent to a second surface of said first polarized beam splitter prism;
said first polarized beam splitter prism directing the first and second color components in the first color set to said first and second light modulators respectively for light modulation;
said first and second light modulators reflecting the light-modulated first and second color components of the first color set back to said first polarized beam splitter prism, and changing the polarization state of the light-modulated first and second color components of the first color set into the first and second polarization states, respectively;
a second light polarization selector for receiving the light-modulated first and second color components of the first color set from said first polarized beam splitter prism, said second light polarization selector changing the polarization state of the first color component of the first color set back into the second polarization state;
a second polarized beam splitter prism for receiving the second color set from said dichroic beam splitter;
a third light modulator disposed adjacent to said second polarized beam splitter prism;
said second polarized beam splitter prism directing the second color set to said third light modulator for light modulation;
said third light modulator reflecting the light-modulated second color set back to said second polarized beam splitter prism, and changing the polarization state of the light-modulated second color set into the second polarization state;
a first projection lens for receiving the first color set from said second light polarization selector; and
a second projection lens for receiving the second color set from said second polarized beam splitter prism.
2. The projection display of claim 1, wherein said first and second projection lenses are disposed adjacent to each other on a common horizontal plane and have parallel optical axes.
3. The projection display of claim 1, wherein said dichroic beam splitter is adapted to allow the second color set to pass therethrough, and is adapted to reflect the first color set for reception by said first light polarization selector.
4. The projection display of claim 3, further comprising a mirror for directing the second color set from said dichroic beam splitter to said second polarized beam splitter prism.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
