The first large area, commercially available, electrically-controllable glazing products sold under the tradename VARILITETM are based on a new liquid crystal film technology called NCAP. The glazing products can be switched in milliseconds between a highly translucent state (for privacy and glare control) to a transparent state (for high visibility) with the application of an AC voltage. The optical and environmental properties are demonstrated to meet the general requirements for architectural glazing use. The first qualified indoor product is described in detail.
