Abstract

A method for making a color separator configured for a large screen display includes covering red, green, and blue subpixels of a phosphor display with a refraction layer, and then ink-jet printing a color selection mask layer onto the refraction layer 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 method for making a color separator configured for an image display apparatus, comprising the acts of:

providing a substrate;

establishing phosphor-based red, green, and blue subpixels on the substrate;

covering the subpixels with at least one refraction layer; and

printing a color selection mask layer onto the refraction layer 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 method of claim 1, wherein the display is a large screen display.

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

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

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

6. The method of claim 1, wherein the color selection 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 method of claim 1, wherein the source is a laser.

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

establishing a mask on a phosphor display, the mask having apertures defining pitches between adjacent apertures, at least one pitch being different from another pitch;

receiving the demanded image; and

directing light onto a display through the mask, wherein the mask is ink-jet printed onto the display.

9. The method of claim 8, wherein the directing act is undertaken using plural light valves, the light valves being controlled in accordance with the demanded image.

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

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

12. The method of claim 8, 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.
