Maybe they can figure out how to embed a solar panel into the display. I guess it would absorb light though so it may be hard to balance with a light emitting display. I wonder if one can be very specific on directionality for both emission (outward direction only) and absorption (inward coming light only.) Logically I would think the emission layer goes on top of the absorption layer. This seems on the face of it possible. I do not know enough about the specifics if it is reasonable to do. I could see it though. Just leave your phone face up on your desk during the day to have it charge.
