CNET was able to get a look at Corning's ultra-thin bendable glass
, and says it is just .1mm thick; it also can bend in half like a piece of paper to a 5mm radius. Polly Chu, Technology Director at Corning, says that in order to produce glass that has a tight bend radius, it needs to be thinner than what is seen on smartphones today. Chu notes that some of the glass being tested in the Corning lab is thinner than a human hair.
Corning is not yet ready to ship a foldable Gorilla Glass which means that the Flexpai, expected to ship this month, will rely on plastic
. That is not as good as glass for protecting the screens used on mobile devices since plastic can scratch, change color over time, and will crease. Those are three things that you won't find with Corning's glass. As for Samsung, the buzz around the water cooler is that a transparent polyimide material will be used to protect the screen on the Galaxy Flex.
"The foldable opportunity is a little bit of a moving target now, because the use case isn't quite and the form factor isn't quite clear. Until these things start to manifest themselves and become more clear we'll have to innovate in different material options in the glass space to see what the right product is... and time our development accordingly."-John Bayne, Vice President and General Manager, Corning Gorilla Glass
