Paper Abstract

The car dashboards we used were original construction. Liquid crystal display works on the twist-nematic effect with color filters. The central element of the dashboard is a digital speedometer. Other displays like tachometer, fuel and temperature gauge are analog. An electronic system assures cooperation with traditional car endowment. Isothiocyanate liquid crystal mixture assures wide range display operation -30 divided by 80 degree(s)C.
