Image display device
First Claim
1. An image display device, comprising:
- a first panel positioned to receive a first light beam and configured to modify the first light beam to produce a first modified light beam;
a first beamsplitter configured to reflect the first modified light beam;
a first filter configured to receive the first modified light beam and configured to filter the first modified light beam to produce a first filtered light beam;
a second panel positioned to receive a second light beam and configured to modify the second light beam to produce a second modified light beam;
a second beamsplitter configured to reflect the second modified light beam;
a second filter configured to receive the second modified light beam and configured to filter the second modified light beam to produce a second filtered light beam;
a third panel positioned to receive a third light beam and configured to modify the third light beam to produce a third modified light beam;
a third beamsplitter configured to reflect the third modified light beam; and
a third filter configured to receive the third modified light beam and configured to filter the third modified light beam to produce a third filtered light beam.

Abstract
A color management system for use with projection displays includes, for example, two or more analyzers positioned to receive light beams as they are emitted from the panels of a color management system. The analyzers are positioned to receive the light beams directly from the image assimilators before the light has passed through another optical element such as a light combiner. The analyzers are configured for producing filtered light outputs with improved contrast relative to the incoming light beams. By positioning the analyzers to receive the light beams directly from the image assimilators, i.e., prior to passage through other optical elements, the analyzers are able to remove substantially all of the noise before it has become indistinguishable, on the basis of polarization, from the light that comprises the desirable image. Accordingly, this embodiment produces images having dramatically improved levels of contrast relative to prior art systems.
