Corning will show off stronger glass for tablets and smartphones

Corning first repurposed its 1960s high-strength, sheet glass technology into “Gorilla Glass” for the original Apple iPhone in 2007. Since that time, Gorilla Glass has gone on to become one of the most popular ruggedized glass substrates used on tablets and smartphones.
Corning has announced that it will be unveiling Gorilla Glass 3 which promises a new composition with enhanced durability.

“These new innovations build on the increasingly important and continually evolving role of highly engineered glass technologies in delivering improved product performance and functionality through touch capabilities, protective cover glass, and device connectivity,” said Wendell P. Weeks, chairman, chief executive officer, and president at Corning.

Corning says that it would be discussing the new orderable Gorilla Glass 3 product and offering hourly demonstrations on the new material.
Corning announced Gorilla Glass 2 at CES 2012, so there should be no surprise at what Corning will announce at CES 2014…

A watch I bought a couple of years back has a synthetic sapphire front surface instead of glass or quartz. I've smashed this watch (unintentionally, of course) against concrete walls, metal railings, rocks, tree bark, you name it -- still not a scratch on it...

If the industry could standardize on screen size and thickness, I can imagine manufacturers just building a set of sapphire screen surfaces, and then simply re-polishing and recycling them from one generation of the device to the next (which would, over time, help amortize the relatively higher cost of synthetic sapphire...)

Not a material scientist, but synthetic sapphire is hard and scratch-resistant, but more brittle compared to gorilla glass. (see the ~45 degree bend video demonstrations for gorilla glass - don't have the link here). Anyhow, it won't completely solve the problem.

You are correct, sapphire is considered fairly brittle. Theoreticaly, the only things that can scratch it are diamond and other sapphires, but that's potentially pointless if it cracks the first time it's smashed against a door handle or falls to the floor,

And remember, watch crystals are only about 38 - 46mm across and are often 2-3mm thick. For a phone, we'd be talking about a much broader unsupported sheet of potentially thinner crystal, neither of which are good for impact resistance. We've got phones that're approaching 7-8mm, we can't have the glass surface be half of that...
