In a few years, the current generation of high-tech LED tail lights and headlights may look quaintly Victorian.
Lighting suppliers are rushing to develop the Next Big Thing: a super-thin lighting source -- dubbed OLED -- that creates a 3D look for instrument clusters, tail lights or brake lights.
An Organic Light Emitting Diode, or OLED, is a layer of material that lights up when electricity is passed through it via two electrodes.
Since it does not need a backlight -- such as a tungsten bulb, a conventional light-emitting diode or even a laser generator -- a vehicle's tail light does not require reflectors or other optics. Moreover, designers can create a 3D look by using multiple OLED layers.
