Apple used to give Sapphire glass over the camera lens usually. In the previous release, Apple has used sapphire glass in the Touch ID of the 5s. Rumors have added up that iPhone 6 screen would be made up of Sapphire. In a video uploaded by Youtube video producer MKBHD has turned up with a spare Iphone 6 front panel which after few rounds of tests was confirmed that it was not pure sapphire display.
The Wall Street Journal reports that Apple has plans to use a sapphire crystal display in the higher-end models of the two versions of the iPhone 6 that it plans to debut this fall. Multiple iPhone 6 rumors have speculated that sapphire could be constrained to either the larger 5.5-inch iPhone 6 or the higher-end models due to cost and production issues, the above publication confirmed.
Apple is investing a considerable amount of money into partner GT Advanced’s sapphire plant, shelling out more than $500 million to outfit the factory with high-output furnaces for sapphire production. Rumors have suggested GT Advanced has the capability to eventually produce enough sapphire to outfit 100 to 200 million iPhones, but other rumors have pointed towards high costs and production problems as limiting factors. Apple is also planning to use sapphire for the upcoming iWatch, according to The Wall Street Journal. The first sapphire displays for the two devices are “expected to roll off production lines this month.”
Sapphire is seen as a desirable material due to its extreme durability and scratch resistance, but many smartphone manufacturers have suggested Apple’s plan to use the material is just a marketing gimmick due to its prohibitive cost.
While Apple may not be able to produce the entire lineup of iPhone 6 displays in sapphire, rumors have suggested that when the factory is fully functional, it will give the company a way to produce massive quantities of sapphire at a low cost, which means a full sapphire lineup could be more feasible for future devices.
