A new patent granted to Apple this week could hint at yet another issue the company has solved. The iPhone, iPod touch, and iPad all look great when you first buy them, but after months of use the cases will no doubt have a few scratches on them. It’s the kind of thing we all put down to general wear and tear, and it is pretty much unavoidable.
The patent Apple has secured is for adding a nitride layer to devices. This layer is transparent and invisible to the eye, but it manages to stop the underlying materials from getting scratched. If Apple coats the next generation of its iDevices in this nitrate layer it could mean an end to scratched cases, or at the very least they stay scratch free for longer.
This is a relatively cheap solution for protecting a device. It’s also thin enough that not only does the underlying materials color come through, but so does its texture.
