Corning Gorilla Glass 4 with improved damage resistance announced

With the Gorilla Glass 3 becoming a standard on most of the smartphones, Corning has launched the next iteration of the protective display glass technology.


Corning Incorporated has announced the Gorilla Glass 4, which is the fourth generation of the Gorilla Glass and is touted to be twice as tough as any other competitive cover glass design in the market. The new glass is supposedly thin and light as previous versions but is formulated to deliver drastically improved damage resistance to improve in-field performance.

The Corning Gorilla Glass 4 is said to be tested for performance when subjected to sharp contact damage, such as asphalt and other real-world surfaces. The glass has superior surface quality with high optical clarity and is available in thickness ranging from 0.4 mm to 2.0 mm.

Speaking about the new Corning Gorilla Glass 4, James R. Steiner, senior vice president and general manager, Corning Specialty Materials, said, “Corning Gorilla Glass has outperformed competing materials, such as soda-lime glass and other strengthened glass, since it was introduced in 2007, and we’re always innovating to push the limits of what glass can do. 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.”
