1. A display comprising:
- a) a first display subunit comprising a first plurality of light emitting elements, each light emitting element of said first plurality designed to emit light in a characteristic wavelength band;
b) a second display subunit comprising a second plurality of light emitting elements, each light emitting element of said second plurality designed to emit light in a characteristic wavelength band; and
c) an optical system configured to optically superimpose each light emitting element of said first plurality with a corresponding light emitting element of said second plurality designed to emit light in a like wavelength band.

44. A method of producing a display, comprising:
-
a) superimposing first and second display subunits having substantially identical arrangements of light modulating elements to form a superimposed display area, wherein each light modulating element of said first display subunit is designed to modulate light in a respective characteristic pattern, and wherein each light modulating element of said first display subunit within said superimposed display area is superimposed with a light modulating element of said second display subunit designed to modulate light in a like characteristic pattern;
b) controlling said first display subunit to produce a first light pattern; and
c) controlling said second display subunit to produce a second light pattern that when superimposed with said first light pattern produces a desired light pattern in said superimposed display area. - View Dependent Claims (52, 55, 56, 57, 74, 75, 76)
