  • Patent number: 12044933
    Abstract: A method for aligning molecular orientations of liquid crystals and/or polymeric materials into spatially variant patterns uses metamasks. When non-polarized or circularly polarized light is transmitted through or reflected by the metamasks, spatially varied polarization direction and intensity patterns of light can be generated. By projecting the optical patterns of the metamasks onto substrates coated with photoalignment materials, spatially variant molecular orientations encoded in the polarization and intensity patterns are induced in the photoalignment materials, and transfer into the liquid crystals. Possible designs for the metamask use nanostructures of metallic materials.

  • Patent number: 12044919
    Abstract: A light control sheet includes a first characteristic and a second characteristic selectively exhibited. In the first characteristic, an absolute value of a change in clarity per unit voltage is greater than an absolute value of a change in haze per unit voltage. In the second characteristic, an absolute value of a change in haze per unit voltage is equal to or greater than an absolute value of a change in clarity per unit voltage. Haze is calculated in accordance with JIS K 7136:2000. Clarity is calculated by 100×(LC?LR)/(LC+LR). LC is an intensity of straight light travelling straight along a travelling direction of parallel light that has entered the light control sheet, and LR is an intensity of narrow-angle scattered light having an angle within ±2.5° relative to the travelling direction of the parallel light.
