Initial Devices Makers, or OEMs, utilize a variety of various type of products to make mobile phone glass. Not to be puzzled with the tech within the screens, we’re describing the real glass that covers them.

Many modern-day mobile phones include some sort of toughened glass face, the most typical which is Corning’s Gorilla Glass. Less typical is the Japanese-made Asahi Dragontrail glass; rarer still is a finishing that’s not glass at all, however Sapphire.

Aside from products, there are likewise differing structures of glass. While mobile phones utilized to utilize a common pane (2D) of glass, we are more frequently seeing curved screens (3D, like on the Samsung Galaxy Edge series) and flat screens with curved edges (2.5 D, like on the V30).

Let’s have a look at the numerous kinds of products utilized to secure screens on your phones and tablets. We’ll check out a few of the distinctions in between them, highlighting a few of the most fascinating and pertinent information.

Corning Gorilla Glass

Gorilla Glass is an alkali-aluminosilicate glass made by the New York-based Corning. Over the last couple of years it’s ended up being the brand of screen glasses, ending up being associated with resilience of screens. Corning created Gorilla Glass to be scratch-resistant, drop-resistant, and crystal clear to guarantee the very best possible image.

Gorilla Glass SR+

Corning ® Gorilla ® Glass SR + is a glass composite created specically for wearables that integrates the famous durability, optical clearness and touch level of sensitivity of Gorilla Glass with remarkable scratch resistance approaching that of high-end watch cover products.

  • Reported: August 2016
  • Application: Smartwatches, wearables
  • Decreases noticeable scratches
  • 70% much better damage resistance over previous generations
  • 5% much better optical transmission over previous generations
  • 25% much better front surface area reflection over previous generations

Gorilla Glass 5

Corning ® Gorilla ® Glass 5– Corning’s newest glass style was created to resolve damage– the best issue of customers, inning accordance with Corning’s research study. The brand-new glass is simply as thin and light as previous variations, however has actually been created to provide significantly enhanced damage resistance permitting enhanced in-field efficiency. Corning ® Gorilla ® Glass 5 has actually been checked for efficiency when subjected to sharp contact damage.

Inning Accordance With Corning, phones with Gorilla Glass 5 can make it through drops of as much as 1.6 meters. Its tech can avoid fractures in up to 80% of falls onto very difficult surface areas from heights of one meter.

  • Reported: July 2016
  • Application: Smart devices, tablets, laptop computers
  • Firmness: 601-638 kgf/mm2
  • Enhanced drop efficiency
  • High maintained strength after usage
  • High resistance to scratch and sharp contact damage
  • Superior surface area quality

Gorilla Glass 4

It was the 4th generation of Corning’s tech where the business chose to take on the concept of being resistant to drops. Keep in mind the commercials for the Android Turbo in late 2014? This was the period where the uncrackable glass removed, providing phones a much harder security over screens. Two times as strong as its predecessor, it certainly altered the video game.

  • Reported: November 2014
  • Application: Smart devices, tablets, laptop computers
  • Firmness: 489-596 kgf/mm2
  • Boosted maintained strength after usage
  • High resistance to scratch and sharp contact damage
  • Enhanced drop efficiency
  • Superior surface area quality

Asahi DragonTrail Glass

Dragontrail glass, like Gorilla glass, is an alkali aluminosilicate Japan-made by the Asahi Glass Business. The high-end of Dragontrail’s line of product, PRO, really sports a greater firmness ranking than Gorilla Glass 5, inning accordance with Vickers Firmness ranking. It must be kept in mind that Corning and Asahi utilize various requirements to determine drop screening, so it’s difficult to compare them side by side.

Dragontrail glass is more typical amongst mid-tier Chinese-manufactured phones, with Western-marketed ones preferring Gorilla Glass.

Dragontrail PRO

  • Reported: September 2016
  • Application: Smart devices, tablets, laptop computers, Televisions
  • Firmness: 542-672 kgf/mm2
  • Scratch-resistant, Crack-resistant
  • More high compression tension readily available
  • Large-size readily available
  • Different density
  • Greater strength than the standard item


  • Reported: 2011
  • Application: Smart devices, tablets, laptop computers, Televisions
  • Firmness: 595-673 kgf/mm2
  • Scratch-resistant, Crack-resistant
  • High compression tension readily available
  • Large-size readily available, Different density
  • 6 times more powerful than sodalime glass


While there isn’t really a “name-brand” maker for Sapphire mobile phone glass, it matters enough to point out here. Instead of making a phone’s screen from glass, as is so typical, it’s made from Sapphire– an exceptionally difficult (and consequently fragile) gem. Maybe the most popular mobile phone with a Sapphire screen is in 2015’s scandal sheet HTC U Ultra.

Though it’s very scratch-resistant, alleviating the requirement for a screen-protector, a Sapphire screen is likewise really fragile, and therefore vulnerable to shattering on effect. While a Sapphire layered mobile phone screen resolves one issue– scratches– it makes another one– drops– even worse.

2.5 D

Sounds like a buzzword? Got ta be something some marketing officer comprised and slapped on a mobile phone’s box, no?

While 2.5 D mobile phone glass is simply visual and ergonomic in nature, without any genuine useful application, it does represent a technological procedure in making beautiful screens.

Samsung’s Galaxy Edge and Keep in mind series usage 3D glass where the whole screen curves, leading to curved sensing units below the glass. On the other hand, 2.5 D glass is totally flat on its face.

This permits OEMs to continue to utilize innovation like Corning Gorilla Glass without difficulty. The additional 0.5 D originates from the curved edges of the screen that curtain over the edges of the phone, producing the bezel-less look that’s so popular nowadays. You’ll discover 2.5 D glass on phones like the LG V30 and the Galaxy S series.
