Gorilla Glass

May 01, 2024

Gorilla Glass is a brand of chemically strengthened glass developed and manufactured by Corning. It is in its eighth generation. Designed to be thin, light and damage-resistant, the glass gains its surface strength, ability to contain flaws, and crack-resistance by being immersed in a hot, potassium-salt, ion-exchange bath.[1]

The alkali-aluminosilicate sheet glass is used primarily as cover glass for portable electronic devices, including mobile phones, smartwatches, portable media players, portable computer displays, and television screens.[2] It is manufactured in Harrodsburg, Kentucky; in Asan, South Korea;[3] and in Taiwan. In October 2017, some five billion devices globally contained Gorilla Glass.[4] While dominating its market, Gorilla Glass faces varying competition from close equivalents, including AGC Inc.'s Dragontrail and Schott AG's Xensation and synthetic sapphire.[5][6][7][4]

Background and development edit

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"[8] marketed as Chemcor. The product was used until the early 1990s in commercial and industrial applications, including automotive, aviation and pharmaceutical uses,[8] notably in approximately 100 Dodge Dart and Plymouth Barracuda racing cars in 1968, where minimizing the vehicle's weight was essential.[9]

Experimentation was revived in 2005, investigating whether the glass could be made thin enough for use in consumer electronics.[10] Although not called Gorilla Glass at the time, it was brought into commercial use with the launch of the iPhone in June 2007.[11][12] The iPhone that Steve Jobs revealed in January 2007 still featured a plastic display. The day after he held up the plastic iPhone on stage, Jobs complained about scratches that had developed on the phone's display after carrying it around in his pocket. Apple then contacted Corning and asked for a thin, toughened glass to be used in its new phone.[13] The scratch-resistant glass that shipped[14] on the first-generation iPhone would eventually come to be known as Gorilla Glass, officially introduced in February 2008.[15] Corning further developed the material for a variety of smartphones and other consumer electronics devices for a range of companies.[16][17][18]

Corning markets the material's primary properties as its high scratch-resistance (protective coating) and its hardness (with a Vickers hardness test rating of 622 to 701),[19] which allows the glass to be thin without being fragile. The glass can be recycled.[16]

In December 2015, Ford announced that it would use the material for the windshield and rear window of its second-generation Ford GT sports car going on sale in 2016.[20] It later spread to mainstream models such as the Ford F-150 and Jeep Wrangler.[21]

Manufacture edit

During its manufacture, the glass is toughened by ion exchange. The material is immersed in a molten alkaline potassium salt at a temperature of approximately 400 °C (750 °F),[22] wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress, giving the glass surface increased strength, the ability to contain flaws,[23] and overall crack-resistance,[24] making it resistant to damage from everyday use.[22]

Generations edit

Gorilla Glass, initially featured on the original iPhone upon its release in June 2007,[11] was formally unveiled in February 2008.[15] By 2010, the glass had been used in approximately 20% of mobile handsets worldwide, or about 200 million units.[25]

Gorilla Glass 2 was introduced in January 2012.[26] The second generation is 20% thinner than the original Gorilla Glass.[27] It was first used on the Samsung Galaxy S III.[28] In October 2012, Corning announced that over one billion mobile devices used Gorilla Glass.[29]

Gorilla Glass 3 was introduced at CES 2013 on January 7.[30] 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.[31][32] Promotional material for Gorilla Glass 3 claims that it is 40% more scratch-resistant in addition to being more flexible.[33] 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 rigidity theory.[34] The first phone to use Gorilla Glass 3 was the Samsung Galaxy S4.[35]

When Gorilla Glass 3 was announced, Corning indicated that areas for future improvements included reducing reflectivity and susceptibility to fingerprint smudges, changing surface treatments, and the way the glass is finished.[27] Antimicrobial Gorilla Glass, with antibacterial ionic silver incorporated into its surface, was introduced and demonstrated at CES 2014 in January.[36]

Gorilla Glass 4 was introduced in November 2014.[37] It has better damage resistance and capability to be made thinner with the same performance as its predecessor.[38] It was first used on the Samsung Galaxy Alpha.[39]

Gorilla Glass 5 was introduced in July 2016.[40] It offers better resistance to cracking from drops and was first used on the Samsung Galaxy Note 7.[41]

Gorilla Glass SR+ was introduced in August 2016.[42] It was designed for wearable mobile devices, focusing on toughness, scratch resistance, and optical clarity.[43] It was first used on the Samsung Gear S3 smartwatch.[44]

Gorilla Glass 6 was introduced in July 2018.[45] It has the scratch resistance of Gorilla Glass 5, but is designed to withstand multiple drops from even greater heights. It was first used on the Samsung Galaxy S10.[46]

Gorilla Glass DX and DX+ were introduced in July 2018, following the launch of Gorilla Glass 6.[47] An extension of Gorilla Glass SR+, Gorilla Glass DX features enhanced antireflective optics with the same scratch resistance of Gorilla Glass, while Gorilla Glass DX+ provides enhanced antireflective optics with superior scratch resistance. While primarily intended for wearable mobile devices, developments were underway to adapt these new glass composites to larger form-factor devices.[47] Gorilla Glass DX+ was first used on the Samsung Galaxy Watch.[48]

Gorilla Glass 3+ was introduced in August 2019.[49] It was designed for value and intermediate segment mobile devices, and its drop performance bridges the gap between Gorilla Glass 3 and Gorilla Glass 5 in this market segment.[49]

Gorilla Glass Victus was introduced in July 2020.[50] It improves both drop and scratch performance and is claimed by Corning to be twice as scratch-resistant as Gorilla Glass 6.[50] It was first used on the Samsung Galaxy Note 20 Ultra.[51]

In July 2021, Corning announced that it will bring its Gorilla Glass DX and DX+ glass composites to cover smartphone camera lenses and said that Samsung would be the first customer to adopt them.[52] The first Samsung phones to use Gorilla Glass DX protection for the cameras were the Galaxy Z Fold 3 and the Galaxy Z Flip 3.[53]

Gorilla Glass Victus 2 was introduced in November 2022.[54] The second-generation Victus has a new composition for improved drop performance on rough surfaces like concrete. In terms of scratch resistance, it is said to be similar to its predecessor.[55] However, according to user reports, the glass is susceptible to micro-scratches, and it has been suggested that this could be due to the use of softer materials for improved resistance to shattering.[56][57] Gorilla Glass Victus 2 was first used on the Samsung Galaxy S23 series.[58]

Gorilla Glass Armor, officially referred to as Gorilla Armor, was introduced in January 2024.[59] While not directly comparing it to the previous generation, Corning claims that the glass performs up to three times better on drop tests onto concrete and is four times more scratch-resistant than competitive aluminosilicate cover glasses. Additionally, it improves visual clarity by reducing reflectance by up to 75% compared to a typical glass surface, enhancing display readability. It was first used on the Samsung Galaxy S24 Ultra.[59]

On October 26, 2011, Corning announced the commercial launch of Lotus Glass, designed for OLED and next-generation LC displays.[69] 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.[70] 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 single product could incorporate both Gorilla Glass and Lotus Glass.[71]

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 OLED device market in Korea. The joint venture is based on Lotus Glass.[72] Lotus XT Glass became available in 2013.[73]

In 2012, Corning introduced Willow Glass,[74] a flexible glass based on borosilicate glass,[75] launched for use as a display substrate.

Ceramic Shield, a ceramic-hardened front glass, was co-developed with Apple and is used on all iPhones from iPhone 12 onwards (except the third-generation iPhone SE).[76]

400 C 750 F 22 wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress giving the glass surface increased strength the ability to contain flaws 23 and overall crack resistance 24 making it resistant to damage from everyday use 22 Generations editGorilla Glass initially featured on the original iPhone upon its release in June 2007 11 was formally unveiled in February 2008 15 By 2010 the glass had been used in approximately 20 of mobile handsets worldwide or about 200 million units 25 Gorilla Glass 2 was introduced in January 2012 26 The second generation is 20 thinner than the original Gorilla Glass 27 It was first used on the Samsung Galaxy S III 28 In October 2012 Corning announced that over one billion mobile devices used Gorilla Glass 29 Gorilla Glass 3 was introduced at CES 2013 on January 7 30 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 31 32 Promotional material for Gorilla Glass 3 claims that it is 40 more scratch resistant in addition to being more flexible 33 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 rigidity theory 34 The first phone to use Gorilla Glass 3 was the Samsung Galaxy S4 35 When Gorilla Glass 3 was announced Corning indicated that areas for future improvements included reducing reflectivity and susceptibility to fingerprint smudges changing surface treatments and the way the glass is finished 27 Antimicrobial Gorilla Glass with antibacterial ionic silver incorporated into its surface was introduced and demonstrated at CES 2014 in January 36 Gorilla Glass 4 was introduced in November 2014 37 It has better damage resistance and capability to be made thinner with the same performance as its predecessor 38 It was first used on the Samsung Galaxy Alpha 39 Gorilla Glass 5 was introduced in July 2016 40 It offers better resistance to cracking from drops and was first used on the Samsung Galaxy Note 7 41 Gorilla Glass SR was introduced in August 2016 42 It was designed for wearable mobile devices focusing on toughness scratch resistance and optical clarity 43 It was first used on the Samsung Gear S3 smartwatch 44 Gorilla Glass 6 was introduced in July 2018 45 It has the scratch resistance of Gorilla Glass 5 but is designed to withstand multiple drops from even greater heights It was first used on the Samsung Galaxy S10 46 Gorilla Glass DX and DX were introduced in July 2018 following the launch of Gorilla Glass 6 47 An extension of Gorilla Glass SR Gorilla Glass DX features enhanced antireflective optics with the same scratch resistance of Gorilla Glass while Gorilla Glass DX provides enhanced antireflective optics with superior scratch resistance While primarily intended for wearable mobile devices developments were underway to adapt these new glass composites to larger form factor devices 47 Gorilla Glass DX was first used on the Samsung Galaxy Watch 48 Gorilla Glass 3 was introduced in August 2019 49 It was designed for value and intermediate segment mobile devices and its drop performance bridges the gap between Gorilla Glass 3 and Gorilla Glass 5 in this market segment 49 Gorilla Glass Victus was introduced in July 2020 50 It improves both drop and scratch performance and is claimed by Corning to be twice as scratch resistant as Gorilla Glass 6 50 It was first used on the Samsung Galaxy Note 20 Ultra 51 In July 2021 Corning announced that it will bring its Gorilla Glass DX and DX glass composites to cover smartphone camera lenses and said that Samsung would be the first customer to adopt them 52 The first Samsung phones to use Gorilla Glass DX protection for the cameras were the Galaxy Z Fold 3 and the Galaxy Z Flip 3 53 Gorilla Glass Victus 2 was introduced in November 2022 54 The second generation Victus has a new composition for improved drop performance on rough surfaces like concrete In terms of scratch resistance it is said to be similar to its predecessor 55 However according to user reports the glass is susceptible to micro scratches and it has been suggested that this could be due to the use of softer materials for improved resistance to shattering 56 57 Gorilla Glass Victus 2 was first used on the Samsung Galaxy S23 series 58 Gorilla Glass Armor officially referred to as Gorilla Armor was introduced in January 2024 59 While not directly comparing it to the previous generation Corning claims that the glass performs up to three times better on drop tests onto concrete and is four times more scratch resistant than competitive aluminosilicate cover glasses Additionally it improves visual clarity by reducing reflectance by up to 75 compared to a typical glass surface enhancing display readability It was first used on the Samsung Galaxy S24 Ultra 59 Comparison of properties edit

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 70 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 single product could incorporate both Gorilla Glass and Lotus Glass 71 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 OLED device market in Korea The joint venture is based on Lotus Glass 72 Lotus XT Glass became available in 2013 73 In 2012 Corning introduced Willow Glass 74 a flexible glass based on borosilicate
