Abstract:
1. A device with an array of display elements that displays images that appear to be three-dimensional, comprising: a first display element that comprises one or more first light-emitting members and two or more rotating concentric first light guides whose rotation guides the directions of the light rays from the one or more first light-emitting members, wherein the first light guides are coaxial, rotating around a first axis; and a second display element that comprises one or more second light-emitting members and two or more rotating concentric second light guides whose rotation guides the directions of the light rays from the one or more second light-emitting members, wherein the second light guides are coaxial, rotating around a second axis, and wherein the second axis is different than the first axis; wherein an outer first light guide has a shape that is fully or partially concave, thereby defining an interior space, and wherein an inner first light guide is located fully or partially within the interior space; wherein at least one of the first light guides has a shape that is fully or partially concave, thereby defining an interior space, and wherein one or more first light-emitting members are located fully or partially within the interior space; and wherein an outer second light guide has a shape that is fully or partially concave, thereby defining an interior space, and wherein an inner second light guide is located fully or partially within the interior space; wherein at least one of the second light guides has a shape that is fully or partially concave, thereby defining an interior space, and wherein one or more second light-emitting members are located fully or partially within the interior space.
