How gorilla Glass Protects your display?

If youve been looking at the list of today smartphone features, almost certainly you have encountered the term Gorilla Glass. Most people know that it is a particular kind of glass that is used on smartphones, tablets, and other similar devices. We will answer a lot of your questions in this article.

What is Gorilla Glass?

Gorilla Glass is a type of toughened glass that is designed to resist damage while remaining thin and light. Corning Inc. invented gorilla Glass. Back in the 1960’s, they built a sturdy glass called Chemcor that was used for both industrial and commercial applications for several decades. In 2005, the company decided to use their existing background with Chemcor and with starting a new research, try to create a new kind of hardened glass that could be used for modern electronics like smartphones and tablets. The outcome was the first Gorilla Glass, which was announced in February 2008.


Advantages of the Gorilla Glass

Your device's screen is one of the most precious possessions for you, and Gorilla Glass protects it. The primary advantage that the durable screen protector offers you is the high-end damage resistance.

Glass’ another advantage is associated with the care taken while manufacturing it. In the whole process, it's avoided the human touch; therefore no flaws will be introduced on the surface. By this approach, the surface tends to be completely cleaner and smoother so it can guaranty an excellent and top class optical clarity for your screen.

The extremely thin layer of the Gorilla Glass ensures its sensitivity to touch. This glass is intended to cover the touch screens, and as such, it needs to be responsive and durable at the same time.


Production Process

Gorilla Glass is manufactured in a world-class using Corning's patent fusion technology. The technology guarantees surface quality, a great optical clarity, and precise dimensional consistency. All the components needed to make it a glass are blended and then melted. This molten glass is made to go through a process named isopipe.

Gorilla Glass is produced from alkali-aluminosilicate, a material which contains minerals such as aluminum, silicon, and oxygen. These materials help reinforce the sheet of glass. In the manufacturing process, the glass is also immersed in a hot (400-degree centigrade) potassium salt ion-exchange bath which further increases its surface strength and damage resistance.

The sodium ions leave the surface of the glass, while the potassium ions enter its surface. Once the glass cools down, these larger ions compress together and create a surface that has more compressive strength.


What types of Gorilla Glass are there?

Since 2005, Corning Inc. has been researching new ways to improve their glass, and they have released five versions of Gorilla Glass. Every new version had significant improvements over its predecessor, and newer Gorilla Glass types are tougher or thinner than the older ones.


Gorilla Glass 1

The first version of Gorilla Glass made its first appearance on the first iPhone, in January 2007. This was the first time that Gorilla Glass was ever used in consumer electronics. It seems that the main reason for choosing gorilla glass was the desire of Steve Jobs to using glass on the Apple's new iPhone, not plastic. But at that time, glass was too fragile, so Jobs met with the CEO of Corning Inc. and, after getting introduced to their work on Gorilla Glass, placed an order immediately.

The Gorilla Glass used on first Apple’s iPhone had an oleophobic coating and thickness of 1.5 mm. It could resist both scratch and crack, as well as fingerprint and smudge.


Gorilla Glass 2

The second iteration of Gorilla Glass was introduced in 2012, with 20 percent lower thickness than the original version. The second version had all other characteristics of its big brother such as toughness and scratch resistance, but it provided all that features with thinner structure. That was perfect for many smartphone manufacturers, as they could now design and fabricate thinner devices.


Gorilla Glass 3

The core feature of Gorilla Glass improved by the third version of this type of glass. In fact, Corning managed to enhance the glass’ toughness and produced a new type of Gorilla Glass that was stronger, more scratch-resistant, and more flexible. Gorilla Glass 3 was debuted in 2013, the year when manufacturers started to become interested in using this tough glass on devices like laptops and hybrid devices with touchscreens.


Gorilla Glass 4

Through surveys, Corning Inc. found that when it comes to their smartphones, people are worried most about dropping them on the ground and cracking their screens. So, for Gorilla Glass 4, they focused on improving the glass and make it a lot more resistant to falls. According to corning's statements, when dropped from a height of 1 meter, Gorilla Glass 4 can “withstand breakage 80% of the time”.


Gorilla Glass 5

The last version of Gorilla Glass was announced in July 2016. It is another version of the corning's glass that is designed to be even more robust than the fourth version. The Gorilla Glass 4 was improved and proved to withstand drops from a height of just one meter. Version 5 has been enhanced to become up to four times more resistant to falls. Corning Inc. says that the last version of Gorilla Glass can survive face-down falls from 1.6 meters height, onto a rough surface, in up to 80% of the times. In other words, a smartphone that features this new type of glass can survive even if you drop it while taking a picture, for example.
