Liquid Crystals for Windows
Our intelligent liquid crystals turn conventional glass into dynamic switchable surfaces that can be dimmed depending on the light conditions, either completely or in segments. It takes only one click to block excessive sun or to provide privacy. Our LCW technology allows for:
- Continuously variable switching
- Design freedom
- Compatibility with all standard frames and curtain walls
Switching within seconds – transparent and color-neutral: brought to you by the liquid crystals licrivision™.
Benefits of our materials for your switchable window application
Licrivision™ is exceptionally durable, temperature- and UV -resistant and has passed long-term testing according to international norms and standards, without failure or performance deterioration. We are working on a constant transmission performance for more than 10 years. Glass products with our liquid crystals have passed DIN EN ISO-12543 testing for laminated glazing. Tests with more than one million switching cycles or long-time continuous switching show no change to the liquid crystals in the product properties. These robust materials of licrivision™ make it the ideal material for dynamic glass applications.
Results of intense one-year tests show that LC windows with licrivision™ can withstand temperatures between –20°C and +100°C, while the liquid crystal material itself has been proven to withstand temperatures in the range from –40°C to +120°C.
What liquid crystals can do for switchable windows
licrivision™ can change normal glass into a dynamic, intelligent surface. It can change its translucency at the touch of a button, or the transmittance of the glass and still retains the core quality of glass for an unchanged view and pleasant indoor climate.
Proven in practice
With our R&D line and pilot line, many pilot installations in this field have shown that liquid crystals for smart glass applications meet the highest demands. The window façade on the west side of our company’s Modular Innovation Center in Darmstadt was fitted with liquid crystal windows for sun protection in early-2015. Switchable windows containing licrivision™ in both the sun protection and privacy control variants were also installed in the new OLED materials production building inaugurated at the Darmstadt site in September 2016. Long-term field tests prove the longevity of the materials. They operate perfectly, from the icy cold of a winter's night to the afternoon heat of a midsummer's day.
