摘要： A liquid crystal device includes carbon nanotube-doped liquid crystal materials that have a fast switching mode. The liquid crystals may be nematic liquid crystals contained in an optically controlled birefringence cell, with a small amount of nanotubes relative to the liquid crystals. The cell may operate between an optical bend state and homeotropic state, where the liquid crystals aligning in a bend state in response to low voltage and transform to a homeotropic state in response to high voltage. The cell may capable of a large change in effective birefringence, or variable effective birefringence enabling self-compensated optical retardation. The liquid crystals may be included with an electro-optical film, which may be formed with polymer encapsulated liquid crystals with the inclusion of at least a small amount of nanotubes sufficient to induce homogeneous liquid crystal dispersion. The electro-optical film may be fabricated by lamination or otherwise onto a substrate.

摘要： A liquid crystal polymer dispersion is formed where liquid crystal encapsulation is produced by a process in which a reactive additive formulation is mixed and photo-polymerized. The polymerizable additive formulation includes monofunctional, multifunctional and photoinitiator compounds in specific composition. The polymerizable additive formulation enhances the control of deformed globule or droplet size, structure integrity, electro-optical properties, and prohibits flow of the liquid crystal as it is encapsulated. A simple process and a controllable system for encapsulating cholesteric materials that provides rugged low-power flexible passively-driven displays. Such displays offer the possibility of lower cost roll-to-roll manufacturing in addition to lighter weight, more rugged and conformable displays.

The method includes the step of preparing a mixture of liquid crystal material, prepolymer, and polarization-sensitive material. The mixture is disposed on a substrate and a combination of UV or visible light or heat treatment is applied while simultaneously inducing phase separation so as to form a layer or microstructure of appropriately aligned liquid crystal material adjacent the substrate.

摘要： A bistable liquid crystal spatial light modulating (SLM) device (SLM) device utilizes the homeotropic and bubble domain texture change of a cholesteric liquid crystal that is responsive to external stimuli, such as electric voltage, light and pressure. The SLM device is configured to be switched between the two stable textures of the bubble domain texture or the fingerprint texture. In addition, the SLM device may be switched between transparent and light-scattering states by the application of an electric field, light irradiation or physical/mechanical pressure. The light transmission state and the light-scattering states of the present invention are also stable in time at zero voltage, and are reversible upon the application of an external field at a different voltage, frequency or wavelength of light.
