Abstract
Novel arrangements of elements (e.g., individual emitters or stacks thereof) produce three-dimensional full-color light-emitting displays. In an embodiment, planar arrays of regularly-spaced elements and electrical conductors can be configured together by staggering the layers'"'"' respective lateral positioning and controlling the pitch between layers. Various advantages may include smooth flow of voxels and boundaries and/or enhanced three-dimensional appearance versus conventional direct stacks.

21. A three-dimensional light-emitting display comprising:
-
a) a first planar array of regularly-spaced repeating elements, and a second planar array of regularly-spaced repeating elements, wherein the centerpoints of closest-adjacent elements within each planar array are spaced apart from each other by a distance d, and wherein each element'"'"'s centerpoint is defined by the position of the element'"'"'s source of visible light;
wherein the second planar array is parallel to the first planar array and is pitched apart from the first planar array by a vertical distance between centerpoints that is a first function of d, and wherein the centerpoints of the elements of the first planar array are staggered apart from the centerpoints of elements in the second planar array by a lateral distance that is a second function of d;b) an array of electrical conductors comprising a first set of electrical conductors arranged so that each element of the first planar array is in electrical contact with two electrical conductors of the first set of electrical conductors configured to energize it, and a second set of electrical conductors arranged so that each element of the second planar array is in electrical contact with two electrical conductors of the second set of electrical conductors configured to energize it; c) wherein the first and second planar arrays together form voxels that each include four elements which elements are together capable of generating full-color light emission, and wherein either; i) the elements of each planar array are arranged orthogonally within each planar array, the elements of the first planar array consist of exactly two colors of elements, the elements of the second planar array are different from the elements of the first planar array, and the second function of d is approximately d/√
