Glass Screens

Gorilla Glass is the trademark for an alkali-terminological sheet glass manufactured by U.S. glass maker Corning. Engineered for a combination of thinness, lightness, and damage-resistance, it is used primarily as the cover glass for portable electronic devices including mobile phones, portable media players, laptop computer displays, and some television screens.[1]

The manufacturer says the material's primary properties are its strength (allowing thin glass without fragility), its high scratch resistance (for protective coating), and its hardness (with a Vickers hardness test rating of 622 to 701)[2] — and that the material can be recycled.[3]

Based on research and development from the 1960s and launched in 2007 for the first iPhone, Gorilla Glass by 2010 had been used in approximately 20 percent of mobile handsets worldwide, about 200 million units.[4] The second generation, called "Gorilla Glass 2", was introduced in 2012. On October 24, 2012, Corning announced that over one billion mobile devices used Gorilla Glass.
