Superimposed displays
First Claim
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;
wherein each of said first and second display subunits comprises light emitting elements of at least two types, each type designed to emit light of a respective characteristic wavelength band, and wherein light emitting elements of said first display subunit are optically superimposed with light emitting elements of the same type in said second display subunit.

Abstract
Various embodiments of methods and systems for constructing and configuring displays constructed from superimposed display subunits are disclosed. A display may be formed by superimposing two display subunits including multiple display elements or pixels which emit or otherwise modulate light. Display subunits may be optically superimposed with an optical system such that a light emitting element in the first subunit is superimposed with a corresponding light emitting element in the second subunit that emits light in a like wavelength band. A method of producing a display may include superimposing first and second display subunits to form a superimposed display area, controlling the first display subunit to produce a first light pattern; and controlling the second display subunit to produce a second light pattern that when superimposed with the first light pattern produces a desired light pattern.

14. 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 of 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; wherein said first display subunit comprises two or more subsets of light modulating elements, each said subset designed to modulate light in a respective wavelength band, wherein each said respective wavelength band is different from the respective wavelength band of at least one other subset of light modulating elements. - View Dependent Claims (15, 16, 17, 18, 19, 20)
