Apple screen glass supplier Corning claims that “it will probably take at least three years before companies start making flexible displays using its new Willow material,” according to a report. Corning Glass Technologies president James Clappin said that companies have yet to come up with products that can fully take advantage of Willow glass, which can roll up in a manner similar to newsprint. Recent reports have suggested that Apple could use Willow to create a curved glass display in its rumored iWatch; Apple is said to be experimenting with curved glass designs, but it appears unlikely that Willow will be used in the immediate future. Corning is currently producing Willow glass, and teaching “very big name” customers how to handle it, Clappin said. [via Bloomberg]
