    摘要: The invention provides a low loss liquid crystal modulator for coloring and shaping a light beam wherein liquid crystal light modulators provide continuous variation in color and intensity output by controlled scattering; the liquid crystal light modulators comprise addressable sheets of light-wave-length size liquid crystal occlusious in a transparent matrix; the modulators employ nematic liquid crystal exhibiting positive dielectric anisotropy; the modulator is employed in varying and coloring output beams to allow for colored data or video transmission; images produced may vary in time as is required for, e.g., color television; the modulator is employed in color projectors for both data and video projection, for color printing, and for colored stage illumination. Low loss transmission of the modulators provides for bright images which can be viewed under high ambient illumination.

    摘要: The invention provides a new liquid crystal display material prepared by the phase separation of a homogeneous solution of liquid crystal and thermoplastic resin to create in situ microdroplets of liquid crystal within a set transparent resin matrix. The new display material is characterized by ease of fabrication and the ability to be reworked by simple heating and cooling of the thermoplastic resin containing microdroplets of liquid crystal. It has been discovered that such a material fabricated from a thermoplastic resin and a liquid crystal having a liquid crystalline phase to isotropic phase transition temperature above the softening temperature of the resin exhibits a reversible field-independent memory.
