Gorilla Glass 4 will protect smartphones against even more abuse

In the smartphone and tablet space there is one brand name that pops up consistently when you speak about protecting screens from scratches and breaks: Corning Incorporated’s Gorilla Glass. The latest generation of Gorilla Glass was announced yesterday by the American company, and if the marketing jargon is to be believed Gorilla Glass 4 is “up to two times tougher than competitive glasses”, which definitely bodes well for the smartphones of the future.

When it came time to test Gorilla Glass 4’s durability, the scientists at Corning analysed hundreds of broken screens and found that ‘sharp contact’ accounted for around 70% of breakages. A sharp contact is basically what happens when you drop your phone on uneven surfaces like pavements, where the jagged edges of stones are the first thing to come into contact with the screen. To simulate this, scientists began dropping phones with Gorilla Glass 4 from a height of one meter onto 180 grit sandpaper, observing that the glass survived the fall up to 80% of the time.

Because of the increased strength in Gorilla Glass 4 over its predecessor, Gorilla Glass 3, Corning is now able to get the same level of protection out of a thinner piece of glass. This should see manufacturers claiming your finger will feel closer to the screen than before in the inevitable Gorilla Glass 4 marketing material.

Corning’s test results are on the company’s website for you to take a look at should you have a need for that kind of information, but the gist of it is that Gorilla Glass 4 is stronger and thinner than anything else the company has ever made.

The new protective layer is set to become available to smartphone and tablet manufacturers this quarter, which means the new crop of gadgets that will be announced next year at CES and Mobile World Congress should offer us the first new models to bear the fruits of all of this research.
