Abstract:
1. A display comprising: a) a first plurality of light modulating elements located on a substrate; b) a second plurality of light modulating elements located on the substrate; c) an optical system configured to optically superimpose each light modulating element of said second plurality with a corresponding light modulating element of said first plurality to produce a superimposed display element, wherein optical superimposition of said first plurality of light modulating elements and said second plurality of light modulating elements forms a plurality of superimposed display elements that together form a superimposed display, and wherein each said superimposed display element produces light modulation equal to the combined light modulation of said light modulating element of said second plurality and said corresponding light modulating element of said first plurality; and d) electronic circuitry configured to control operation of light modulating elements of said first plurality of light modulating elements to supplement operation of light modulating elements in said second plurality of light modulating elements to produce a desired light modulation pattern in said superimposed display.
