Energy-saving liquid crystals
Touchscreen mobile devices have revolutionized our day-to-day lives and fundamentally altered our communication culture. When you swipe your fingers across the screen of your mobile device, you are setting into motion liquid crystal molecules that were likely made by Merck KGaA, Darmstadt, Germany. Roughly a tenth of a gram of this liquid crystal mixture is needed to illuminate a smartphone or tablet.
Yet mobile devices these days must have more than vivid, high-resolution displays – they also need to consume as little energy as possible. To meet this challenge, we have developed the innovative liquid crystal technology known as UB-FFS, which was launched in 2014.
How does this technology work? Let's say you’re watching a video on a display with the brightness turned all the way up, which accounts for half of a mobile device's power consumption. This is where UB-FFS comes into play. UB is short for “ultra brightness”, called such because it allows the liquid crystal layer to transmit up to 15% more of the display's backlighting. What's more, this “extra” light is utilized to provide superior image resolution. Devices with UB-FFS consume up to 30% less energy and have a longer battery life. This technology also improves display quality, which allows users to more easily read the screen from a variety of angles.
