US 6788354 B2 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.
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 3. The method of 4. The method of 5. The
