3D image display with binocular disparity and motion parallax

A device with an array of display elements that displays images that appear to be three-dimensional, wherein at least one of these display elements comprises:

• one or more light-emitting members:
• wherein a light-emitting member is selected from the group consisting of:
• a light source within the display element;
• and an exit point for light channeled from a light source external to the display element;
• —and—
• two or more rotating concentric light guides whose rotation guides the direction of light rays from the one or more light-emitting members:
• wherein changes in the directions of the light rays exiting a display element and changes in the contents of those light rays are coordinated to show different contents from different viewing perspectives and thereby display images that appear to be three-dimensional;
• wherein a first light guide has a shape that is fully or partially concave, thereby defining an interior space, and wherein a second light guide is located fully or partially within that interior space;
• wherein at least one of the light guides has a shape that is fully or partially concave, thereby defining an interior space, and wherein one or more light-emitting members are located fully or partially within that interior space;
• wherein a light guide guides light by one or more means selected from the group consisting of:
• holes or transparent portions that allow light to pass through, barriers that block the passage of light, lenses or other optics that refract or channel light, and mirrors or other surfaces that reflect light;
• and
• wherein the two or more light guides rotate in similar, or different, directions selected from one or more selections in the group consisting of:
• clockwise rotation, counter-clockwise rotation, and oscillating rotation.

• wherein the array of display elements is arrayed on a surface with a shape selected from one or more selections in the group consisting of:
• a flat surface;
• and a curved surface, such as a portion of a cylinder, sphere, or parabolic solid;
• —and—
• two or more rotating concentric light guides whose rotation guides the direction of light rays from the one or more light-emitting members:

• wherein the light guides have shapes selected from one or more selections in the group consisting of:
• sphere, hemisphere, or other portion of a sphere;
• geodesic sphere, dome, or other three-dimensional structure comprised of polygonal elements;
• disk or ellipse with concave or convex sides;
• multi-faceted lens, converging ascending three-dimensional spiral (like a swirl of soft ice cream);
• multi-faceted lens;
• and parabolic solid;
• and
• wherein the light guides of a display element change the latitude and longitude of the angles by which light rays exit that display element, wherein latitude may be defined as the angle of a light ray relative to the plane of the array of display elements, and wherein longitude may be defined as the rotational angle, or polar coordinate, of a light ray relative to the rotational axis of a light guide.
