Abstract
Projection assemblies are provided herein for use in a display system. According to one exemplary embodiment, the projection assembly includes an illumination source and a plurality of co-planar modulator panels. A method of modulating light is also provided herein that includes generating multi-component light, splitting the multi-component light into a plurality of component beams, and modulating the component beams with a plurality of co-planar modulator panels to form a plurality of sub-images.
Claims22
A projection assembly, comprising:
- an illumination source configured to provide multi-color component light;
- color separation optics optically coupled to said illumination source that are configured to divide said multi-color component light into beams of different color components;
- a plurality of co-planar modulator panels each configured to respectively receive a said beam of a particular color component and modulate that beam;
- and
- a plurality of projection lens systems, each optically coupled to a respective modulator panel,
- wherein each of said projection lens systems differs in at least one first order property depending on a color of a said beam modulated by a corresponding modulator panel.
A display system, comprising:
- an image processing unit;
- at least one illumination source configured to provide multi-color component light;
- color separation optics optically coupled to said illumination source that are configured to divide said multi-color component light into beams of different color components;
- a plurality of co-planar modulator panels in optical communication with said illumination source, wherein each is configured to respectively receive a said beam of a particular color component and modulate that beam;
- and
- display optics in optical communication with said co-planar modulator panels;
- wherein said display optics comprise a plurality of projection lens systems, each optically coupled to a respective modulator panel,
- wherein each of said projection lens systems differs in at least one first order property depending on a color of a said beam modulated by a corresponding modulator panel, and
- wherein said first order property comprises either focal length or magnification.
A method of modulating light, comprising:
- generating multi-component light;
- splitting said multi-component light into a plurality of component beams of different colors;
- modulating said component beams with a plurality of co-planar modulator panels to form a plurality of sub-images;
- projecting each modulated component beam with a different corresponding projection lens system;
- and
- configuring each of said projection lens systems to differ in at least one first order property depending on a color of a corresponding modulated component beam.
