Sapphire crystals are transparent as that of glass, but have some peculiar advantage that may soon feel the Smartphone users. The display made of Sapphire is extremely durable and scratch resistant.
MIT Technology Review is of the opinion that sapphire could be in the future Smartphone displays. Some manufacturers are already experimenting with it for a long period of time. Sapphire is made from molten Aluminum oxide. The production process has long been a closely guarded secret. Therefore, the single crystal is very expensive. While a gorilla glass, which Apple previously built into the iPhone, it costs only $ 3, you have to spend tenfold for a sapphire display.
But By the competition and cheaper production methods, but the price could fall rapidly.
The advantage of the sapphire crystal is the low sensitivity to impact. Scratch the disc gets only at very high pressure, which cannot happen in everyday life. Moreover, the material is characterized by a good light transmittance.
These reasons have also moved Apple to making the camera lens of the iPhone 5 and the new iPod Touch from SAPPHIRE CRYSTAL. It is the second hardest of all transparent materials and can therefore hardly break. By the end of this year, the first high-end Smartphone are equipped with a solid display.
