Abstract: A bistable cholesteric liquid crystal switchable window has two stable states in the absence of an applied voltage. A first stable state is a planar state which is transparent or reflective for visible light. A second stable state is a focal conic state which is opaque for visible light. The window can be switched from the first stable state to the second stable state via a first voltage pulse and from the second stable state to the first stable state via a second voltage pulse. The first voltage pulse and the second voltage pulse may have the same frequency.

Abstract: A transport device comprises: a fluid cell comprising parallel substrates; an anisotropic electrolyte disposed in the fluid cell; and electrodes configured to apply an AC electric field to the anisotropic electrolyte disposed in the fluid cell. A substrate of the fluid cell includes a pattern that induces a director distortion pattern in the anisotropic electrolyte disposed in the fluid cell.

Cargo, such as particles, gas bubbles, or fluid, is dispersed in the anisotropic electrolyte and transported in the fluid cell by the induced electrokinetic flow of the anisotropic electrolyte. The induced electrokinetic flow may be linear, curvilinear, circular so as to induce mixing, depending on the predesigned director pattern.

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.

Abstract: A polymer-dispersed blue-phase (PDBP) liquid crystal film is formed from a polymer-based latex and blue-phase liquid crystals that are combined using an emulsification process or a polymerization-induced phase separation process. The resultant PDBP liquid crystal film includes droplets formed by the polymer-based latex that encapsulate the blue-phase liquid crystals therein, so as to allow the blue-phase liquid crystals to have a blue phase at room temperature. As such, the PDBP liquid crystal film is conducive for use in manufacturing processes, such as LCD (liquid crystal display) manufacturing processes, while providing desirable optical features, such as field-induced birefringence at low switching voltages.

Abstract: A frequency controlled electro-optical device includes a substrate having transparent conductive control sections patterned thereon to selectively control the optical state of an electro-optical layer. Each of the control sections are partially electrically isolated from each other by crack lines, which allows for electrical communication between adjacent/proximate control sections to occur. As such, an electrical control signal applied directly to one control section forms an electric field in that control section, and also induces an electrical field in adjacent control sections that are not in direct receipt of the control signal. Therefore, the number of electrical connections required for coupling to a driving circuit to operate the device is minimized, thereby allowing the device to be fabricated with reduced complexity and cost.
