Corning, maker of what is known as Gorilla Glass and is used in various products (including Apple’s devices), has promised an even stronger and more scratch-resistant version of its glass product coming in time for CES 2013. Gorilla Glass is renown for its strength, and is found on almost every mobile device in widespread production.
There are, of course, various other products that are chemically similar (or in some cases, identical) to Corning’s Gorilla Glass. Corning is, however, more or less the market leader, with the vast majority of mindshare.
As more and more devices utilize glass in a more prominent fashion, stronger solutions are necessary. The trend of having glass featured prominently on more than the screen was first popularized by the iPhone 4, and was carried in to the 4S. The iPhone 5 changes up the design somewhat, though glass is still one of the most prominent design features. Other devices, like Google’s Nexus 4 which is built by LG, also include glass prominently, though LG’s solution is marketed as being a proprietary implementation that isn’t quite glass.
Glass on a phone received a bad rap from the iPhone 4 and 4S. The back of the device could shatter when dropped from a certain distance, and while not everyone experienced such issues, some did. Thankfully, the glass is incredibly easy to replace.
