Nematic liquid crystal materials for displays

Nematic liquid crystals are being used in a variety of display devices that capitalize on unique characteristics of these organic fluids. This paper discusses the purification and preparation of nematic liquid crystals, their operating temperature ranges, and the extent to which their properties meet the requirements of current dynamic-scattering and field-effect displays. While device performance can be further improved by tailoring the material, product acceptance will be principally determined by other factors such as reliability, packaging, and price reduction.
