Corning, the company that makes Gorilla Glass, doesn't think that phone makers will be able to take advantage of flexible screens for at least three more years.

Gorilla Glass is a robust screen material already found in handsets ranging from iPhones to the Samsung Galaxy S3 and beyond.

Not content with strength, Corning has also gone after bend-ability with its latest iteration, known as Willow, which is a glass that can be bent and rolled up like newspaper.

But therein lies the problem, according to Corning president James Clappin.

"People are not accustomed to glass you roll up, " he said in an interview with Bloomberg. "The ability of people to take it and use it to make a product is limited."

That doesn't mean a three-year wait before we see any Willow-toting products; rather that some simple gadgets may start using it (solar panels, for example) before it makes its way to the complex computational beast you keep in your pocket.
