In researching types of displays that can be folded or bent, Apple is continuing to work on technology so iPhone displays themselves could “heal” the inevitable wear and tear.

Apple has been working on a foldable iPhone for at least nine years, and it’s also investigated ones where the screen can be rolled up. In each case, the issue is of making these screens work — and not be damaged by the folding or rolling.
Now a newly-granted patent suggests a way of both minimizing damage, and of doing something about it when it happens. “Electronic Devices With Flexible Display Cover Layers,” proposes mixing rigid and flexible areas for a display, and then also utilizing what Apple calls “self-healing.”
