Novel Liquid Crystal Could Triple Sharpness of Today's Televisions

An international team of researchers has developed a new blue-phase liquid crystal that could enable televisions, computer screens and other displays that pack more pixels into the same space while also reducing the power needed to run the device. The new liquid crystal is optimized for field-sequential color liquid crystal displays (LCDs), a promising technology for next-generation displays. “Today’s Apple Retina displays have a resolution density of about 500 pixels per inch,” said Shin-Tson Wu, who led the research team at the University of Central Florida’s College of Optics and Photonics (CREOL). “With our new technology, a resolution density of 1500 pixels per inch could be achieved on the same sized screen. This is especially attractive for virtual reality headsets or augmented reality technology, which must achieve high resolution in a small screen to look sharp when placed close to our eyes.” Although the first blue-phase LCD prototype was demonstrated by Samsung in 2008, the technology still hasn’t moved into production because of problems with high operation voltage and slow capacitor charging time. To tackle these problems, Wu’s research team worked with collaborators from liquid crystal manufacturer JNC Petrochemical Corporation in Japan and display manufacturer AU Optronics Corporation in Taiwan.”
