Gorilla Glass 5 – great for swinging through trees

One of the success stories is Corning selecting the name Gorilla Glass for its hardened, toughened, scratch-resistant, glass protection used by many smartphones and tablets.

Gorilla Glass 5 (GG5) is the latest iteration and like Rocky Movies you can count on many more!

GG5 will survive a 1.6-metre “shoulder height” drop onto hard, rough surfaces 80% of the time – apparently up to four times better drop failure than its nearest competitors. That is just as well as a recent global study by Toluna reveals that 85% of smartphone owners have dropped their phone at least once per year, and 55% are plain clumsy. Most drops occur at anything from waist to shoulder height, usually during selfies.

“With each successive generation of Corning Gorilla Glass, we have taken cover glass technology to new levels. Gorilla Glass 5 is no exception, extending Corning’s advantage in drop performance over competitive glasses,” said John Bayne, vice-president and general manager, Corning Gorilla Glass. “With many real-world drops occurring from between waist and shoulder height, we knew improving drop performance would be an important and necessary advancement.”

Owners of Gorilla Glass 4 (GG4) protected phones should not fret – it is about twice the strength of its competitors when dropped from a metre.

Smartphone makers have long been looking at how to reduce screen damage from drops. Apple went down the path of Sapphire crystal even investing US$2 billion in the now failed GTAT foundry.

The key lies in both strength and thickness. While Corning recommend a .6mm thickness, the majority of smartphone makers opt for .4mm. Then there issues about whether the glass is protected by a bezel, whether it's curved (like the Samsung Edge) and how much edge protection it has for corner drops.
