Gorilla Glass simply refers to the registered trademark name of a specialized glass developed and manufactured by Corning. It’s light weight, slimness, and strength make it one of the widely used glasses in smartphones.
Corning had introduced “muscle glass” with several experiments conducted from 1950s. The glass marketed as “Chemor” was used in automotive, aviation and pharmaceutical industries. Steve Jobs wanted a strong glass to be used in his phone instead of plastic as plastic glasses were prone to cracks. At that time, Corning was not set up for mass production but Jobs placed an order for a ton of Gorilla Glass motivating Corning to take the risk. For this purpose, those experiments were rejuvenated which gave birth the use of gorilla glass in I phone which was released in 2007.
Gorilla Glass 2 is 20 percent thinner than the original Gorilla Glass. Gorilla Glass 3 is up to three times more scratch-resistant than the previous version, with enhanced ability to resist deep scratches. It’s design had first use of atomic-scale modeling. After Gorilla Glass 3, Corning indicated that areas for future improvements would be reducing reflectivity and susceptibility to fingerprint smudges, and changing the surface treatments and the way it is finished.
Gorilla glass 4 is of same thickness and scratch resistance properties than its prior version. But this time Corning focused on accident related impact damages that shatter the phone screen which is a real issue to be dealt by the phone user instead of the minor scratches.It is twice as stronger than its counter competitors. It says to survive 80% of 3.3 feet flat drop which is the emulation of real life surfaces keeping the phone intact. Today Corning states that over three billion mobile devices used Gorilla Glass.
