With the evolution of touchscreen, smartphones and electronic gadgets became more ergonomic. This technology enhanced the graphical user interface. In spite of visual interaction, now the display became a virtual slate to write, click, and drag the media. Because of these finger interactions with the touchscreen, our gadgets get tiny scratches on the screen and it decreases the clarity.
To prevent scratches of touchscreens, millions of cell phones, laptop computers and other portable electronic devices are protected by Gorilla glass.
What is Gorilla glass?
Gorilla® glass is a very transparent, unscratchable, unshatterable, hard, thin, lightweight & scratch resistant glass and introduced by Corning®, the New York based manufacturer of glass, ceramics, and related materials, primarily for industrial and scientific applications.
This is a surprising matter that Gorilla® glass is not a new invention and this was invented in 1960 and originally named “Chemcor”. At that time its only practical application was for use in racing cars, where strong, lightweight glass was needed.
How it is made?
A glass consists of a thin sheet of alkali-aluminosilicate, is strengthened using an ion-exchange process which forces large ions into the spaces between molecules on the glass surface. In a 400°C molten potassium salt bath, the larger potassium ions replace the smaller sodium ions in the glass. As the glass cools, it becomes a high level of compressive stress glass that helps protect the surface from mechanical damage.
It isn’t scratch proof, just scratch resistant!
Hardness of Gorilla Glass is comparable to that of sapphire, which is 9 on the Mohs scale of hardness. Normal glass is much softer, closer to a 7 on the Mohs scale. The increased hardness means you’re less likely to scratch your phone or monitor from daily use or contact with other items in your pocket or purse.
The only thing that will scratch your Gorilla glass is tiny particles of hard minerals you might find on the floor. Sometimes these things do get on your phone if you drop it or if it gets blown up by wind. You need to take care your phones on beaches during weekends.
From earth to heaven!
Steve Jobs met Wendell Weeks, the CEO of Corning in 2006 for a strong, scratch-resistant glass for Apple’s iPhone and Gorilla® glass introduced by Corning in Apple iPhones.
Now Gorilla® glass supply products to all the leading electronics companies eg. Samsung, LG, Sony etc.
According to Subrat Patnaik from Reuters, Corning shares were up 2.8 percent in premarket trading in the starting of 2015. In March, the company completed the acquisition of Samsung Electronics’ fiber optics business. The company’s net income rose to $407 million, or 29 cents per share, from $301 million, or 20 cents per share. Core net sales were $2.43 billion.
Now Corning® announced to unveil plans for sapphire-like phone screen. Engineers are working on a display material that the company says is as tough as Gorilla Glass 4, and almost as scratch resistant as sapphire.
