Some analysts believe that 2013 will be the year that some smartphone OEMs begin using sapphire in their flagship devices. Apple is an obvious possibility as the biggest company that’s publicly marketing its use of the material, but Google is also rumored to use sapphire in the upcoming Motorola “X Phone.”
Talk of this possibility began last year, with Sterne Agee supply checks finding prototype smartphones with sapphire displays in the works. Most of the sapphire industry sells into the LED industry, and incremental opportunities in smartphones could be enormous. Sterne Agee estimated that the smartphone industry translated into 9 billion square inches of material in 2012, which towers over the 150 million square inches used by the LED industry over the same time. If sapphire were able to penetrate just 2% of the smartphone market, the industry’s addressable market would double.

The story of Corning‘s Gorilla Glass dates back over six decades. The glass maker accidentally made a product that no one was interested in using, and for years it was known as Chemcor and simply had no addressable market. In the early ’70s, Corning gave up trying to sell the stuff and the formula gathered dust for 40 years.
That was until Steve Jobs came around and wanted to cover Apple‘s iPhone with the material, since most smartphone displays predating Apple’s device were covered in plastic that was easily scratched. In the years since, Gorilla Glass has grown to become one of Corning’s most important growth businesses, thanks in large part to smartphone adoption and Apple effectively standardizing the material’s use in high-end mobile devices.

Gorilla Glass is included in Corning’s specialty materials segment and is the primary reason why that operating segment has grown from just 6% of sales in 2009 to an impressive 17% of revenue in 2012.
In November, Corning guided the Gorilla Glass business to $1 billion in annual revenue, a target that it subsequently hit. That was up 44% from 2011, and the majority of the $1.3 billion in revenue that specialty materials generated in 2012. Gorilla Glass also carries gross margins that are much higher than the corporate average.
It turns out that there may be a threat on the horizon to Gorilla Glass, and one that Apple may be catalyzing. Should Corning be scared of sapphire?
Monkey business
Last week, MIT Technology Review published a report on the possible future use of sapphire in smartphone screens, which could potentially replace Gorilla Glass eventually. This threat isn’t at all imminent, as the cost differential remains very high, so most smartphone vendors wouldn’t yet consider adopting it.
A Gorilla Glass display cover currently costs less than $3, which is much cheaper than the $30 that a similar sapphire display would set an OEM back. Eventually, the cost of sapphire could decline to below $20 due to competition and technological advances.
Such a pricey component would put a serious damper on margins. For example, the iPhone 5’s bill of materials excluding manufacturing was estimated at $199, so an extra $27 for the display’s cover material would be a 14% increase in component costs that would represent a gross margin reduction of 4%. While Apple is one of the few smartphone OEMs that could technically afford this type of hit, it certainly doesn’t want to.
Sapphire is much stronger and more scratch resistant than glass, which would make it an ideal candidate if costs permit. At the same time, Corning isn’t resting on its laurels and has now launched Gorilla Glass 3, which includes what the company calls Native Damage Resistance for improved durability. The first smartphone to be unveiled with Gorilla Glass 3 was Samsung’s Galaxy S4 that was shown off earlier this …read more
