Gorilla Glass 4

Corning Incorporated announced its latest breakthrough innovation in consumer electronics material design, the revolutionary Corning® Gorilla® Glass 4, which is up to two times tougher than any competitive cover glass design now in the market. The new Gorilla Glass 4 has been formulated to address consumers’ No. 1 issue – screen breakage from everyday drops.

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.

Corning scientists examined hundreds of 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 thousands of 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:

Gorilla Glass 4 is up to two times tougher than competitive glasses

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.
