Why OLED lighting will soon shine on you - CNET. No, some alien species is not about to invade the planet. However, Organic, Light Emitting Diodes (OLED), which we have been seeing in new TVs, are already beginning to appear in home and office ready designs that are flat, because they are naturally diffused, and use far less energy than previous light sources. We are now familiar with LEDs in our TVs. They are the reason we have flat TVs. But, they still require diffusion, and in light bulbs, the traditional looking bulb has prevailed. No more. You library, conference room, and offices will all have flat panel OLED lighting in the future; or, if you want, now. Get rid of the glare of those fluorescents. Go Organic.
