As per a report from JP Morgan Securities Ltd., Apple will limit the number of screens using sapphire glass, to 10 million devices. That number represents below 1% of the whole smartphone market. Based on the analysts who wrote the report, Apple might restrict the use of sapphire glass this year to the 128GB model of the 4.7 inch iPhone 6. With the material costing $30 to $35 over Gorilla Glass, it would make sense for the maker to use it at first on the more costly models of the device.
Apple connected analyst Ming-Chi Kuo of KGI Securities, earlier mentioned that the 64GB 5.5 inch Apple iPhone 6 would be the only model that could take benefit of sapphire glass. Based on the JP Morgan research, yields of sapphire glass smartphone displays might only be in the area of 50%, which explains the more expensive compared to Corning’s Gorilla Glass. Talking about Gorilla Glass, Corning says that tests in the laboratory show that sapphire glass is less difficult to break than its material.
Besides the iPhone, there was talk that Apple would use sapphire on its iWatch. But a check of the supply chain by JP Morgan, suggests that not every version of the Apple iWatch will feature sapphire glass.
