Gorilla Glass is a brand of specialized
developed and manufactured by , now in its fifth generation, designed to be thin, light and damage-resistant. This type of glass is not unique to C similar glasses include
Xensation.
The - sheet glass is used primarily as cover glass for portable electronic devices, including , ,
displays, and some
screens. It is manufactured in , USA; , K and Taiwan.
The glass gains its surface strength, ability to contain flaws, and crack-resistance by being immersed in a hot potassium salt ion-exchange bath.
Corning experimented with chemically strengthened glass in 1960, as part of a "Project Muscle" initiative. Within a few years they had developed a "muscled glass" marketed as Chemcor. The product was used until the early 1990s in commercial and industrial applications, including automotive, aviation and pharmaceutical uses, notably in approximately one hundred 1968
, where minimizing the vehicle's weight was essential. Experimentation was revived in 2005, investigating whether the glass could be made thin enough for use in consumer electronics. It was brought into commercial use when Apple asked Corning for a thin, it was used in the new .
Corning further developed the material for a variety of
and other consumer electronics devices for a range of companies.
The manufacturer markets the material's primary properties as its high scratch-resistance (protective coating) and its hardness (with a
rating of 622 to 701), which allows the glass to be thin without fragility. It can be recycled.
By 2010 the glass had been used in approximately 20 percent of mobile handsets worldwide, about 200 million units. 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. Gorilla Glass 2 is 20 percent thinner than the original Gorilla Glass.
Gorilla Glass 3 was introduced at . According to Corning, the material is up to three times more scratch-resistant than the previous version, with enhanced ability to resist deep scratches that typically weaken glass. The promotional material for Gorilla Glass 3 claims that it is 40% more scratch-resistant, in addition to being more flexible. The design of Gorilla Glass 3 was Corning's first use of atomic-scale modeling before the material was melted in laboratories, with the prediction of the optimal composition obtained through the application of .
When Gorilla Glass 3 was announced Corning indicated that areas for future improvements included reducing reflectivity and susceptibility to fingerprint smudges, and changing the surface treatments and the way it is finished. Antimicrobial Gorilla Glass with ionic silver, which is antibacterial, incorporated into its surface was demonstrated in early 2014.
Gorilla Glass 4, with better damage resistance and capability to be made thinner with the same performance as its predecessor, was announced at the end of 2014.
Gorilla Glass has also addressed the automobile market. Ford Motor Company announced it will be using the material for the front and rear windshields on its
sports car beginning in 2016.
During its manufacture, the glass is . The material is immersed in a
at a temperature of approximately 400 °C (750 °F), wherein smaller
ions in the glass
ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high
at the surface, giving the glass surface increased strength, ability to contain flaws, and overall crack-resistance, making it resistant to damage from everyday use.
On October 26, 2011, Corning announced the commercial launch of Lotus Glass, designed for
and next-generation
displays. The intrinsic thermal consistency of Lotus Glass allows it to retain its shape and quality during high-temperature processing. Decreased compaction and variation during the crystallization and activation step further reduce stress and distortions to the substrate. This enables tighter design rules in advanced backplanes for higher resolution and faster response time. According to Corning, Gorilla Glass is specifically a cover glass for the exterior of display devices while Lotus Glass is designed as a glass substrate to be used within liquid crystal display panels. In other words, a product could use both Gorilla Glass and Lotus Glass. On February 2, 2012, Corning Incorporated and Samsung Mobile Display Co., Ltd. signed an agreement to establish a new equity venture for the manufacture of specialty glass substrates for the
device market in Korea. The joint venture is based on Lotus Glass. Lotus XT Glass became available in 2013.
In 2012, Corning introduced Willow Glass, a flexible glass based on , launched for use as a display substrate.
