  • Merck Developing Liquid Crystal Smart Windows
Jan 2015
DARMSTADT, Germany, Jan. 15, 2015 — Merck KGaA has developed a liquid crystal mixture that, when used in windows, can adjust the intensity of incident daylight in seconds to reduce energy consumption in buildings.

The mixture, called Licrivision, is placed between two panes of glass. The crystals are brought into various alignments by applying voltage.

Licrivision will be able to optimize light and thermal impact on glazed surfaces, conserving significant amounts of energy, the company said.

Approximately one-third of global carbon dioxide emissions result from maintaining the interior temperature of buildings with glass facades, the company said.

liquid crystal
A type of material that possesses less geometrical regularity or order than normal solid crystals, and whose order varies in response to alterations in temperature and other quantities. Liquid crystals are characterized by phase varieties, including cholesteric, nematic and smectic. The optical properties of liquid crystals are familiar from their use in displays, known as LCDs.
