Abstract
A motion and animation display is disclosed, including multiple nanostructure arrays oriented at differing relative angles of rotation corresponding to multiple frames of an animation image, wherein the multiple nanostructure arrays are formed on a single substrate layer. An optical display device is also disclosed, including a substrate having a surface, a first frame of an animated image comprising a first optical sub-wavelength nanostructure array formed on or in the surface of the substrate, and a second frame of an animated image comprising a second optical sub-wavelength nanostructure array formed on or in the surface of the substrate, where the second nanostructure array is rotated relative to the first nanostructure array by a first relative angle of rotation. A method of manufacturing a motion and animation display comprising multiple nanostructure arrays oriented at differing relative angles of rotation is also disclosed.
