Abstract:

Studies are made on several basic areas relating to the properties and behavior of liquid crystal LC mixtures for use in dynamic scattering DS electro-optical applications, particularly in dc-activated matrix displays at elevated temperatures. These studies include the analysis of the major factors affecting DS characteristics, the development of methods to formulate new LC mixtures with desirable predicted properties for DS displays, investigations of structural effects on the viscosity of LC components of negative dielectric anisotropy, and examination of the dc-DS properties and lifetime of improved LC mixtures used at elevated temperatures. New LC eutectic mixtures with wide nematic ranges are shown to be operable in the 20 to 71 deg C range, with good storage stability in the -60 to 80 deg C.
