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.
