Gorilla Glass 4 to toughen smartphone screens

Glassmaker Corning has unveiled the super tough Gorilla Glass 4, the latest version of its hardened glass covers that save smartphone and tablet screens from damage.

The new material is about twice as tough as Gorilla Glass 3, claims Corning.

Gorilla Glass 4 provides at least two times improved damage resistance over competitive aluminosilicate glass, as measured by retained strength after damage events, resulting in improved mechanical durability of the glass to in-field damage events, such as drops.

Gorilla Glass 4 survives up to 80 percent of the time

Soda-lime glass, as deployed in today’s commercial devices, breaks nearly 100 percent of the time.

Gorilla Glass 4 is manufactured using Corning’s proprietary fusion draw process. It maintains the thinness, durability, and optical clarity for which Gorilla Glass is known, while dramatically improving drop performance.

Gorilla Glass is the cover glass of choice for device manufacturers around the globe. Over 40 manufacturers have designed Gorilla Glass into a total of 1,395 product models, and have branded Gorilla Glass touch cover glass as a key selling feature. Since its launch in 2007, Gorilla Glass has been featured in more than 3 billion devices.

“With Gorilla Glass 4, we have focused on significantly improving protection against sharp contact damage, which is the primary reason that mobile devices break. Dropping and breaking a phone is a common problem, and one that our customers have asked us to help address,” said Corning in a statement.

In tests by the company, Gorilla Glass 4 survived up to 80 percent of drops from a height of one metre, compared to Soda-lime glass, which broke nearly always.

This new development should help Corning dominate the hardened-display glass market.

Gorilla Glass is currently used by Apple iPhones, the Samsung Galaxy series, Sony Xperia phones and almost every leading phone and tablet.
