摘要： A new liquid crystalline light modulating cell and material are characterized by liquid crystalline light modulating material of liquid crystal and polymer, the liquid crystal being a chiral nematic liquid crystal (16) having positive dielectric anisotropy and including chiral material in an amount effective to form focal conic and twisted planar textures, the polymer being distributed in phase separated domains (15) in the liquid crystal cell in an amount that stabilizes the focal conic and twisted planar textures in the absence of a field and permits the liquid crystal to change textures upon the application of a field. In one embodiment, the material is light scattering in a field-OFF condition and optically clear in a field-ON condition, while in another embodiment, the material is optically clear in a field-OFF condition and light scattering in a field-ON condition. In still another embodiment, the material exhibits stability at zero field in a colored, light reflecting state, a light scattering state and multiple stable reflecting state therebetween, as well as being optically clear in the presence of a field.

摘要： A liquid crystal optical device comprising a pair of substrates provided with electrodes and a layer containing a liquid crystal material sandwiched between the pair of substrates, wherein said layer is formed by irradiating light to a solution of a nematic liquid crystal material and a photo-curable vinyl compound selected so that the refractive index of the resulting cured product agrees to either the ordinary refractive index (n₀) or the extraordinary refractive index (n e ) of the nematic liquid crystal material used, or the refractive index (n x ) of the nematic liquid crystal material when it is randomly oriented, held between the pair of substrates provided with electrodes, to cure the photo-curable vinyl compound and fix the resulting phase separation of the nematic liquid crystal material and the cured product.

摘要： The present invention relates to a taillight assembly that includes a light source for emitting light and a light source enclosure having a light transmissive portion for transmitting light from the light source to an illumination zone. A portion of the enclosure includes a material that is affixed to selected regions of the light transmissive portion. By electrically energizing the material the light transmitting properties of the material can be altered for performing different taillight functions. A drive circuit is electrically coupled to the material in each region for selectively energizing the material and thereby controlling the functional light output of each region. All taillight functions can be accomplished by activating the bands on the light transmissive portion, including running light, brake light, reverse light, parking light and turning signal.

摘要： A display system includes a unit configured to provide information, and a plate extending away from the unit in at least one direction. The plate is configured to receive input light and to provide ambient light that may be related to the information. In response to voltage levels, the plate is substantially transparent in a transparent mode and substantially light scattering in a scattering mode to provide the ambient light.
