Corning has announced a new version of Gorilla Glass DX that has been specially optimized for use in smartphone cameras. The material should be almost as scratch-resistant as sapphire glass and offer interesting optical properties that can improve image quality.
So far, Gorilla Glass DX is mainly known for smartwatch displays, but the company has now announced in a press release that the scratch-resistant material will also be offered for smartphone cameras in the future. In addition to regular Gorilla Glass DX, Corning also offers Gorilla Glass DX +, which is said to be almost as scratch-resistant as sapphire glass, while Corning dispenses with a traditional anti-reflective coating, which can usually be easily scratched.
Nevertheless, Gorilla Glass DX is said to capture 98 per cent of the available light and only lose 2 per cent through reflections – according to Corning a considerable advance, since conventional coatings reflect a full 5 per cent of the incident light. This difference may hardly be relevant in practice, but the larger and more high-quality smartphone cameras become, the more important it is to protect against scratches and similar damage, which can have a negative effect on image quality.
It is currently unclear when the first smartphones that will make use of Corning Gorilla Glass DX or Gorilla Glass DX + will hit the market. However, Corning has confirmed that Samsung is the first smartphone manufacturer to use this material in the cameras of its devices. It remains to be seen whether the material will also be used in future iPhones, because, according to Apple, they are already using sapphire glass, although switching to Gorilla Glass DX should save costs.
