Development of Energy Efficient Bistable Liquid Crystal Light Shutter

The aim is to develop an energy-efficient bistable liquid crystal light shutter. The bistable cholesteric liquid crystal light shutters are used in energy-saving buildings, cars, and photovoltaic devices. Cholesteric liquid crystal light shutter technologies have potential impact due to several good factors like transparency, scattering, reflection, bistability, easy implementation, and being less expensive in the process without much complexity. These films keep houses cool during the summer, and according to the US Department of Energy’s National Renewable Energy Laboratory (NREL), the application of smart windows in buildings is likely to save up to 8% of a building’s total energy consumption. Globally, in the display market, South Korea accounts for 47% of the display technology powerhouse, despite a lack of core materials. Japan accounts for more than 70% of current material and technology in terms of national competitiveness. Therefore, for the establishment of the domestic display industry, the development of new materials and device technology is absolutely required.
