Peer+ uses liquid crystals to quickly adjust window darkness.

Merck KGaA has taken full control of Peer+, a Dutch developer of liquid-crystal windows, by acquiring the 30% of the firm it doesn’t already own. Through Peer+, Merck, the world’s largest supplier of liquid crystals, aims to offer smart windows that reduce energy consumption in buildings. Electrically activated liquid-crystal windows can be changed from colorless to tinted to control the thermal activity of external light. Peer+ operates a pilot production line in Eindhoven, the Netherlands.
