  • Publication number: 20210286178
    Abstract: Various embodiments set forth high-resolution liquid crystal displays and components thereof. In some embodiments, light emitted by a high-resolution green color liquid crystal display is combined, via a combiner, with light emitted by at least one lower-resolution red and blue color liquid crystal display. The red and blue color display(s) may include a single display or two displays positioned on opposing sides of the combiner. The combiner may be a dichroic or polarization-based combiner. Combined light from the green color display and the red and blue color display(s) is passed through collimating optics, such as a pancake lens or a Fresnel lens, toward a viewer's eye.

  • Patent number: 11067855
    Abstract: A method for aligning a layer of photopolymers includes projecting light onto a rotating optical element and asymmetrically focusing the light transmitted through the rotating optical element onto a layer of photopolymers. The asymmetrically focused light is swept across different regions of the layer of photopolymers while a direction of polarization in the light is varied due to the rotation of the first optical element, producing a pattern of orientations for the layer of photopolymers. The method can be incorporated in a raster-scanning process to produce an alignment pattern in a layer of photopolymers with a large surface area, and is faster and provides improved precision and/or uniformity of the alignment pattern compared to currently available methods. An apparatus for aligning the layer of photopolymers is also disclosed.
