Corning today announced the Corning Gorilla Glass 4, which the company claims is up to two times tougher than any competitive cover glass design now in the marketand has been formulated to address screen breakage issues from everyday drops. Corning scientists examined broken devices and found that damage caused by sharp contact accounted for more than 70 percent of field failures. The scientists then developed new drop-test methods that simulate real-world break events, based on hours analyzing cover glass that had broken in the field or laboratory. The scientists used the new methods to drop devices face down from one meter, such that the cover glass directly contacted a rough surface. They found that Gorilla Glass 4 is up to two times tougher than competitive glasses; it survives up to 80 percent of the time and that soda-lime glass, as deployed in today?s commercial devices, breaks nearly 100 percent of the time.

Since its launch in 2007, Gorilla Glass has been featured in more than 3 billion devices.

Corning has started offering product sampling and shipments for Gorilla Glass 4.
