KEY FACT
Ceramic Shield is a form of glass that includes ceramic nano–crystals. Ceramics are stronger than glass but they’re also more opaque, which isn’t ideal for displays; nano– crystals are so tiny, they don’t block light and impede transparency. You’ll find Ceramic Shield on the front but not the back of the iPhone 12.
THE iPHONE 12 range includes a new kind of glass: Ceramic Shield. It’s four times tougher than the glass in the iPhone 11 handsets, and it’s both harder and more scratch–resistant too.
Like most of the smartphone glass in the world, Ceramic Shield was developed in association with Corning of Gorilla Glass fame. What makes this glass different is that it contains tiny ceramic nano–crystals embedded in the structure.
