An advanced alkali-aluminosilicate glass technology developed by Corning that is used in a variety of screens for mobile devices like smartphones and tablets as well as displays for PCs and TVs. The scratch- and impact-resistant qualities in Gorilla Glass, combined with its incredibly thin profile, enable it to protect device displays without adding significant weight or interfering with capacitive touch screens.
The first generation of Gorilla Glass was used in the screen of the original iPhone from Apple that debuted in 2007. Gorilla Glass 2 became available in 2012 and offered a 20% thinner profile than the original Gorilla Glass.
The most recent development in Gorilla Glass was announced in early 2013. Gorilla Glass 3 with Native Damage Resistance offers “enhanced scratch resistance, reduced scratch visibility and better retained strength once a scratch does occur,” according to Corning. The first product to employ Gorilla Glass III, the Samsung Galaxy S4, became available in April 2013.
While Gorilla Glass is now the predominant technology used in protecting mobile device screens, it may face competition in the future from another Corning product, Willow Glass, which offers flexible, bendable qualities that make it ideal for wearable computing devices like Apple’s rumored iWatch device.
