Corning Working on Folding Glass for Future Folding Smartphones


2019 is the year of the folding phone, so hot right now, but one thing often overlooked in these new phones is the fact they use plastic displays.

It should come as no surprise that smartphone manufacturers have had to switch to using plastic displays on their folding phones because glass doesn't fold. These plastic displays result in less protection when they come to daily wear and tear. The screens can scratch a lot easier, and when folded multiple times there is a possibility of a crease developing.

Corning is attempting to create a solution to this folding display problem. During a recent interview with Wired a Corning executive said they are working on a new type of glass which is 0.1mm thick and can bend at a 5mm radius.

“Glass today, the current choices out there, they’re not optimal [for folding smartphones],” said John Bayne, an executive with Corning’s Gorilla Glass unit. “In a glass solution, you’re really challenging the laws of physics, in that to get a very tight bend radius you want to go thinner and thinner, but you also have to be able to survive a drop event and resist damage.”

Corning believes their new bendable glass solution will be ready for use in consumer devices in the coming years around the same time folding phones become mainstream.
