"High performance liquid crystals for vehicle displays," published in Optical Materials Express, reports results of Shin-Tson Wu and colleagues, who developed 3 new liquid crystal mixtures that overcome upper and lower operation temperature limitations. According to Wu, liquid crystals should have clearing point higher than 100°C (212°F) and melting point below -40°C (-40°F). Accomplishment was brought about by mixing one dozen 3- and 4-ring compounds together with LMW compounds.
