When Apple iPhone X was released, Apple said that iPhone X has the best display screen in the world. Of course, these "most" series have been updated on Apple's new iPhone XS, iPhone XS Max and iPhone XR. The three new iPhone devices have the best screens and the most durable screen protector glass on smartphones today, and there are still scratches.
Because of this, Apple's research on these screen-protected glass has not stopped. It turns out that this is why Apple can always stand at the forefront of the smart phone field, according to Apple's patent application filed with the US Patent and Trademark Office in March 2017. Look, Apple is working on new screen-protected glass, and these patents show that the new glass has excellent scratch resistance and protects the screen from scratches.
This patent application refers to a hard outer layer with an intermediate layer between the metal substrate and the outer coating. The latter can be made of ceramic or hard carbon based materials with all the hardness of the diamond. The outer layer has a thickness between 0.5 microns and about 3 microns and is harder than the intermediate layer. The "intermediate layer" has a size between 8 microns and 30 microns.
The name of the patent application is "Abrasion resistant surface treatment on a metal casing on a metal casing", according to which the coating provides improved wear resistance and dent resistance. The patent application adds: "Describes a coating that provides improved wear resistance and recess resistance." It must be said that this patent is really "popular", if it can be mass-produced, then the film age Is it past? It’s really true that the supplier of Apple is ready to be eliminated by Apple’s new technology.
