Self powered spreadable OLED's? Yeah, Right! C'mon, this isn't possible but..."Because solar cells and OLEDs work on similar, but opposite, principles, it is possible to make materials that both take light and turn it into electricity and also do the opposite to provide a controllable display."
If this comes to pass, tech will be everywhere, persuasive to a fault.
Tokitaro Hoshijima at Mitsubishi Chemicalexplains:
"What I want to create is a world that does not need power sockets." He goes on to describe how his paste applied to the back of a phone could be enough to charge the device when exposed to light.
By the same token, researchers at Sumitomo Chemical have created a similar organic solution that can be sprayed onto a surface to create an OLED screen.
Such a display could be on a rollable piece of plastic or even applied directly to a wall. The solar-charging properties described above mean it would never need to be plugged in.
Blue-sky projects like these typically take years to bear fruit, but both companies are looking at getting usable prototype devices ready within the next two years.
Pigs may fly after all.
