It would seem that LED technology is, again, evolving to greater extremes. I recently heard about a British company that is currently designing an LED-based wallpaper. Yes, I just said wallpaper.
Apparently, the wallpaper uses a chemical coating that glows, lighting up a room like natural sunlight would. The coating somehow utilizes organic light-emitting diodes (OLEDs), so the wallpaper comes with all the energy saving and efficiency LEDs bring. Interestingly, an electrical current will run through the wallpaper, but it is reportedly safe to touch.
