World's First ''Roll-to-Roll'' Manufactured OLED

I'll start this off with a little background info. A Organic Light Emitting Diode (OLED)is thin organic material between two electrodes. This organic material lights up when current is applied. OlEDs are also much more efficient than traditional lighting.
OK, so now that you have a bit of background info, you are probably wandering what this "Roll-to-Roll" thing is. It means they are "printed" like newspaper. This allows for dirt cheap production of highly efficient lighting. The benefits are obvious, but there are some cool things too, such as light emitting wallpaper for your house.
