Display system with low and high resolution modulators
View Patent ↗A display system is provided, the system including an illumination source configured to produce light and direct light along an optical path, a plurality of color filters disposed in the optical path configured to generate a plurality of colored light beams, and a spatial light modulator disposed in the optical path adapted to receive and adjust the colored light beams to produce an image.
1. A method for displaying an image, comprising:
generating a multi-pixel low-resolution color image; and
generating a high-resolution color image by spatially modulating individual pixels of the low-resolution color image.
2. The method of claim 1 wherein generating the low-resolution color image includes emitting light beams from a plurality of spatially-separated color emitting elements.
3. The method of claim 2 wherein generating the low-resolution color image includes emitting light beams from a low-resolution color modulator.
4. The method of claim 1 wherein generating the low-resolution color image includes directing light through a plurality of color light filters configured to selectively emit a plurality of color light beams which collectively form a multi-beam low-resolution color light array.
5. The method of claim 1 wherein the step of generating a high-resolution color image includes controlling individual mirrors of a high-resolution spatial modulator.
6. The method of claim 1 wherein generating the low-resolution color image includes spatially modulating a light source with a liquid crystal spatial light modulator to form a multi-beam color light array.
7. The method of claim 1 wherein generating the low-resolution color image includes both color and spatially separating incident light into a plurality of color light beams.
8. A method for displaying an image, comprising:
generating a low-resolution color image;
coupling the low-resolution color image to optical fibers; and
generating a high-resolution color image by refining the low-resolution image.
9. A method for displaying an image, comprising:
generating a low-resolution color image, wherein generating the low-resolution color image includes both color and spatially separating incident light into a plurality of color light beams with a digital light filter; and
generating a high-resolution color image by refining the low-resolution image.
10. The method of claim 9 wherein the digital light filter moves a filter medium into and out of the optical path of a light source.
11. The method of claim 10 wherein the filter medium includes an array of stacked cyan, yellow, and magenta filters.
12. A method for displaying an image, comprising:
generating a low-resolution multi-color image defining an array of discrete colored light beams; and
generating a high-resolution multi-color image by selectively refining each discrete colored light beam of the low-resolution image.
13. The method of claim 12 wherein generating the low-resolution multi-color image includes emitting light from a plurality of red-emitting elements, green-emitting elements and blue-emitting elements, spatially-separated to generate a low-resolution pattern of red, green and blue light.
14. The method of claim 12 wherein generating a high-resolution multi-color image includes controlling individual mirrors of a high-resolution spatial modulator.
15. The method of claim 12 wherein generating the low-resolution multi-color image includes both color and spatially separating incident light.
16. The method of claim 15 wherein generating a high-resolution multi-color image includes controlling individual mirrors of a high-resolution spatial modulator to spatially modulate the discrete colored light beams of the low-resolution multi-color image.
17. A method for displaying an image, comprising:
generating a low-resolution pattern of plural differential light beams; and
spatially modulating the each differential light beam to refine the low-resolution pattern, thereby producing a high-resolution image.
