OLEDs: The Light Idea

TIME writes: "In the palm of my hand is a near paper-thin, rectangular glass tile with a mirror finish. It's wired to an electric switch. Flick it on and the glass instantly lights up, emitting a warm, bright glow not unlike sunlight, although it remains cool to the touch. Switch it off and the glow immediately disappears. The wondrous object is an organic light-emitting diode, or OLED, a first cousin of the better-known LED. An embryonic technology — there are only a handful of commercial products available — OLED has the potential to revolutionize the world's $100 billion lighting industry."
