Apple has a new patent that could pave the way for future solar-powered mobile devices, according to AppleInsider. The new intellectual property describes a method for embedding a solar array within a layer that includes touch sensors, and which can all be fit within a flexible display module, in order to save space in its ever-shrinking electronic devices.

The patent is a modified version of one granted to the company previously, which described the same thing but for touch-sensitive surfaces that didn’t include a display in their makeup. Instead, it described the system but for touch-sensitive surfaces only, giving it limited utility value in contemporary devices.
