Gorilla Glass Maker Constructs Flexible 'Willow' Glass

Paul Lilly

Corning is best known for its ultra durable, scratch resistant Gorilla Glass found on a number of handheld and mobile device applications, but has now developed a type of ultra slim glass that can wrap around objects, opening the door to a world of possibilities. The flexible glass, called Willow Glass, is ultra-slim and ultimately ahead of its time, but according to Corning, it can still be used for increasingly thin devices while the world waits for bendable gadgets.

"Displays become more pervasive each day and manufacturers strive to make both portable devices and larger displays thinner. Corning Willow Glass provides the substrate performance to maintain device quality in a thin and light form factor," said Dr. Dipak Chowdhury , division vice president and Willow Glass program director. "Currently manufacturing in a sheet-to-sheet process, we expect Corning Willow Glass to eventually allow customers to switch to high-throughput, efficient roll-to-roll processing, a long-awaited industry milestone."

Corning says its Willow Glass is specially formulated to perform exceptionally well for electronic components like touch sensors, leveraging glass's natural hermetic properties as a seal for OLED and other moisture and oxygen-sensitive technologies.

Willow Glass can be processed at up to 500 degrees Celsius, which enables a roll-to-roll process similar to how newsprint is created, Corning says.
