The display device is comprised of directional pixels. Each directional pixel has a plurality of facets having a constrained viewing angle. Each facet has a point source of light that emits light with a controllable luminescence and hue. In this regard, each facet of the directional pixel has a constrained viewing angle and independent luminance and hue. ## Claims ### Claim 1 An image display device, comprising: a three-dimensional array of directional pixels, wherein all of the directional pixels in the three-dimensional array include a plurality of facets with each facet of the plurality of facets oriented toward an observer and comprising a unique and separate point source of light directed to the observer and with each point source of light configured to emit light in a unique direction; and a controller operable for controlling the light from the facet. ### Claim 2 (depends on 1) The image display device of claim 1, and further comprising a mechanism combined to the array of directional pixels operable to move the array of directional pixels within a volume of space to provide a 3D image. ### Claim 3 (depends on 2) The image display device of claim 2, wherein the mechanism dithers a movement of the array of directional pixels in order to remove an edge-artifact in the 3D image. ### Claim 4 (depends on 1) The image display device of claim 1, wherein the three-dimensional array of directional pixels has a space between each of the adjacent directional pixels so that the facet on each of the directional pixels is generally unobstructed. ### Claim 5 (depends on 4) The image display device of claim 4, wherein the space between each of the directional pixels is substantially equal to a volume of the directional pixel. ### Claim 6 (depends on 1) The image display device of claim 1, wherein each directional pixel has 6 facets arranged in a cubical configuration. ### Claim 7 (depends on 6) The image display device of claim 6, wherein the three-dimensional array of directional pixels are arranged in a chequered pattern with a space between each directional pixel. ### Claim 8 (depends on 7) The image display device of claim 7, wherein a mechanical mechanism oscillates the array of directional pixels. ### Claim 9 (depends on 7) The image display device of claim 7, wherein a mechanical mechanism dithers a movement of the array of directional pixels in order to remove an edge-artifact in a 3D image. ### Claim 10 (depends on 1) The image display device of claim 1, wherein the point source of light includes light generated from at least one chosen from a group including a light emitting diode, a laser diode, and an optical fiber carrying light from a common light source. ### Claim 11 (depends on 1) The image display device of claim 1, wherein each point source of light can emit a red, green, and blue light. ### Claim 12 (depends on 1) The image display device of claim 1, wherein each directional pixel includes a plurality of facets, wherein each of the plurality of facets on each of the directional pixels has a normal vector, wherein the normal vectors of each of the plurality of facets on the directional pixel are at an angle with respect to each other. ### Claim 13 (depends on 12) The image display device of claim 12, wherein at least one of the normal vectors has a component vector in an x, y, and z direction. ### Claim 14 (depends on 1) The image display device of claim 1, wherein each point source of light is controlled independently by the controller. ### Claim 15 (depends on 2) The image display device of claim 2, wherein the constrained viewing angle of facet provides a variable distance between each facet and an observer which creates a depth between each facet to create a stereoscopic display. ### Claim 16 (depends on 1) The image display device of claim 1, wherein the point source of light emits light has a luminance and a hue and a polarization property, and the luminance, the hue and the polarization property are each controlled by the controller. ### Claim 17 (depends on 1) The image display device of claim 1, wherein a mechanical mechanism moves the array of directional pixels in order to provide stereoscopic depth perception to an observer. ### Claim 18 (depends on 1) The image display device of claim 1, wherein all of the directional pixels in the array remain static with respect to each other.
