Sapphire glass will find its way into smartphone displays, GT Advanced (GTAT) insists. Sapphire, used in the iPhone 5's camera lens, is thinner and ~3x stronger/scratch-resistant than Gorilla Glass (GLW). But a sapphire display costs ~$30, whereas a Gorilla Glass display costs less than $3. GT is hoping its furnaces, which can be upgraded to support larger crystals at little cost, will narrow the gap to 3x-4x. Industry analyst Eric Virey, who thinks sapphire's cost could fall below $20 in a couple years, expects "some high-end smartphones using sapphire in 2013." (previous)
