The news comes from Taiwan’s Apple Daily reports that Apple and Foxconn have been doing assembly tests on the effectiveness of sapphire displays which may be introduced in the iPhone 6.
Foxconn has managed to successfully build an initial run of 100 iPhone prototypes with sapphire glass screens.
The publication also writes that Apple’s sapphire suppliers, Synopsys and Bern Optics, have invested in equipment and special tools recently.
Last year in November it was reported that Apple had signed an agreement with GT Advanced Technologies, a company that processes the sapphire, and had invested $578 million to make up a stock of sapphire panels high enough to meet demand in the coming years.
Sapphire displays could replace the traditional Corning Gorilla Glass, providing greater resistance to shocks.
