What is sapphire?
Sapphire is an expensive natural gem. Sapphire screen is made by purifying ordinary gemstones. It basically does not display blue, but it has very high hardness.
Sapphire screen technology has actually appeared for some time. For example, the glass of Heuer watches and military vehicles all use sapphire technology. The hardness of sapphire is second only to diamond. By purifying its elements and applying them to some transparent glass panels, technology manufacturers can achieve better hardness performance than traditional chemically reinforced glass.
Apple only uses the home key and camera glass of the iPhone 5S.
Development prospect of sapphire
Sapphire has excellent optical properties, mechanical properties and chemical stability. Its unique structure, excellent mechanical properties and good thermal properties make sapphire crystal an ideal substrate material for LED, large-scale integrated circuit and so on. Its characteristics of high hardness and erosion resistance are more praised by the manufacturing industry. According to the latest data, if calculated by dimensional hardness, sapphire is about three times that of Corning "Gorilla" glass used in Apple mobile phone cover glass.
The agency forecast report shows that with the large-scale application of sapphire in mobile phone lens, home key and screen saver glass, the market demand proportion of sapphire will increase from 15% in 2013 to 55% in 2015.
