Abstract: An optical element includes a display device and an angular occlusion filter disposed over at least one surface of the display device. The angular occlusion filter may be configured to modulate one or more of transmission, reflection, and polarization of image or ambient light incident upon the display device.

Abstract: A device is provided. The device includes a first Pancharatnam-Berry phase (“PBP”) lens, and a second PBP lens stacked with the first PBP lens. Each of the first PBP lens and the second PBP lens includes a liquid crystal (“LC”) layer. Each side of the LC layer is provided with a continuous electrode and a plurality of patterned electrodes. The patterned electrodes in the first PBP lens are arranged non-parallel to the patterned electrodes in the second PBP lens.

Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling structure located at the input end for coupling light into the waveguide body, and an output coupling structure located at the output end for coupling light out of the waveguide body, where the waveguide body includes a layer of an optically anisotropic organic solid crystal. Such an optical element may have low weight and exhibit good color uniformity while presenting a 2D diagonal field-of-view of at least approximately 10°.
