—The Bulb Is Flat “Organic light-emitting diodes are taking shots at incandescent and fluorescent light bulbs” EVEN AS consumers rush to replace their incandescent light bulbs with compact fluorescents, lighting companies are developing a technology that could render all the bulbs on today's store shelves obsolete: solid-state lighting based on organic light-emitting diodes (OLEDs). Originally intended for colorful alphanumeric and computer displays, OLEDs promise lighting companies both energy savings and novel design. Conventional incandescent light bulbs have dominated electric lighting since the 19th century. In these lights, an electric current passes through a tungsten filament.
