Abstract

A variable pitch color selection mask for configured for an image display apparatus. A substrate having phosphor-based red, green, and blue subpixels is covered by a refraction layer. The color selection mask layer is printed onto the refraction layer, with the mask layer being configured to shield the blue and green subpixels from a first beam, shield the red and green subpixels from a second beam, and shield the red and blue subpixels from a third beam.

Claims

1. A color separator configured for an image display apparatus, comprising:

a substrate having phosphor-based red, green, and blue subpixels;

at least one refraction layer covering the subpixels; and

a mask layer on the refraction layer, the mask layer being configured to shield the blue and green subpixels from a first beam, shield the red and green subpixels from a second beam, and shield the red and blue subpixels from a third beam.

2. The separator of claim 1, wherein the display is a large screen display.

3. The separator of claim 1, wherein the display is a phosphor display.

4. The separator of claim 3, wherein the phosphor display operates at atmospheric pressure.

5. The separator of claim 1, wherein the mask is ink-jet printed onto the refraction layer.

6. The separator of claim 1, wherein the mask defines plural excitation light apertures defining variable pitches established based on the locations of the respective excitation light apertures relative to the display.

7. The separator of claim 1, wherein the source is a laser.

8. A separator for producing a demanded image, comprising:

a mask juxtaposed with a phosphor display, the mask having apertures defining pitches between adjacent apertures, at least one pitch being different from another pitch.

9. The separator of claim 8, wherein light beams are directed from plural light valves through the apertures and onto the display, the light valves being controlled in accordance with the demanded image.

10. The separator of claim 8, wherein the display is a phosphor display.

11. The separator of claim 10, comprising operating the phosphor display at atmospheric pressure.

12. The separator of claim 8, wherein the mask is ink-jet printed onto the display.

13. The separator of claim 9, wherein the mask is configured to shield blue and green subpixels of the display from a first beam, shield red and green subpixels from a second beam, and shield red and blue subpixels from a third beam.
