Corning announces Gorilla Glass 4

Corning has announced Gorilla Glass 4, the latest version of the chemically-strengthened glass that has been used in iPhones, iPod touches, and iPads. Version 4 promises “dramatically improved performance” against drops on rough surface such as jagged streets, sidewalks, and parking lots, as screen breakage is “the #1 consumer complaint, according to Corning’s research.” Corning promises that the new version of Gorilla Glass withstands drops up to two times better than competing designs, while being just as thin and light as prior versions; it delivers marked anti-drop improvements at any thickness it’s manufactured to, and can withstand more pressure at a 0.4mm thickness than version 3 Glass at 0.7mm. While Apple sought to replace Gorilla Glass with manufactured sapphire screen covers from GT Advanced, that venture dramatically fell apart earlier this year, leaving Corning as the supplier for most of Apple’s device glass.
