  • Patent number: 11681194
    Abstract: Various embodiments set forth liquid crystal (LC) patterning control systems in which LCs are aligned using locally applied magnetic fields. The index of refraction experienced by light propagating through an anisotropic LC is dependent on orientation. As a result, a phase difference may be imparted to an optical beam that is passed through, or reflected from, an array of LCs whose orientations are controlled via locally applied magnetic fields. In some embodiments, the locally applied magnetic fields may be generated by driving currents through wires that intersect at micro or nanomagnetic particles or at magnetic domains, or by applying voltages to micro or nanocoils wrapped around high-permeability cores, among other things.

  • Patent number: 11656504
    Abstract: In a liquid crystal apparatus, a liquid crystal is provided in a cavity surrounded by a seal material between a first substrate and a second substrate, and the liquid crystal is aligned in a diagonal direction formed by corners 10a1, 10a3. Between a pixel area and the seal material, a first groove is formed along a side 20a6 from the corner 10a1 toward a corner 10a2. When a first pump is driven, the liquid crystal of the pixel area is drawn from a first end of the first groove on the corner 10a1 side, and the liquid crystal is ejected from a second end into the pixel area. As a result, a liquid crystal flow from the side of a side 20a7 toward the side of a side 20a9 occurs in the pixel area, and thus the liquid crystal can be smoothly circulated.
