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.
Glass based windows 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 performance of the liquid crystals and hence not to the performance of the device. These robust materials of licrivision™ make it the ideal material for dynamic glass applications.
Since the licrivision™ liquid crystal material itself has been proven to withstand temperatures in the range from –40°C to +120°C, results of intense one-year tests show that LC windows with licrivision™ can easily withstand temperatures between –20°C and +100°C.
Allows instant switching (< 1 sec) from light to dark Is usable in tough environmental conditions (high temperature and intense UV radiation) Enables a variety of colors – in particular gray Operates on low voltage Protects vehicle interior and passengers against heavy heating Reduces electric consumption, by reducing need of air climatization Car sunroofs have issues with energy loss, heat gain and cooling costs. licrivision™ solar control enhances glass performance in terms of energy efficiency and sustainability by preventing energy loss and controlling solar heat intake with the upside potential of converting the unused light into electricity. It gives you the ability to access real color neutrality, along with fast switching. With the flick of a switch, the transmission of the sunroof will change from light to dark while maintaining a crystal-clear view
A liquid crystal display (LCD) consists of many optical switches, called pixels, which are arranged next to each other and can be controlled individually. Each pixel consists of three subpixels for the primary colors, which can be mixed. The pattern of light and dark pixels creates the full image seen by the viewer. Because almost no electricity flows through the LCD, this type of display is extremely energy efficient.
We offer customer-specific liquid crystal mixtures for every LCD technology, such as the classic twisted nematic (TN) technology that made the breakthrough of personal computing notebooks possible in the 1990s. Further technologies include vertical alignment (VA) and the polymer stabilized VA variant (PS-VA), in-plane switching (IPS), and fringe field switching (FFS), as well as the development of ultra-brightness fringe field switching (UB-FFS). The technology that is best suited depends on the requirements of the end device.
Our pursuit is progress for people everywhere. That's why we take a closer look at things, ask questions and think ahead.
We've been around for 350 years, yet our majority owners are still the descendants of Friedrich Jacob Merck, the man who founded our company in Darmstadt, Germany in 1668.
Since then, we have become a truly global company, with almost 53,000 employees in 66 countries working on breakthrough solutions and technologies. In 2017, we invested a total of € 2.1 billion in research and development.
We are Merck. The only exceptions are the United States and Canada. Here we operate as EMD Serono in the Biopharma business, as MilliporeSigma in the Life Science business, and as EMD Performance Materials in the materials business.
