Abstract
The invention relates to an organic light-emitting diode () with an organic layer sequence (). The organic layer sequence () comprises a first organic emitter layer () for generating electromagnetic radiation of a first wavelength range () and a second organic emitter layer () for generating electromagnetic radiation of a second wavelength range (). A charge carrier generation layer sequence (), CGL for short, is arranged between the first () and the second () emitter layer, and the first emitter layer () and the second emitter layer () are electrically connected in series via said CGL. The CGL () additionally has a converter material which converts the radiation of the first () and/or the second () wavelength range at least partially into radiation of a third wavelength range (). In this manner, the organic light-emitting diode () can emit mixed light with components of the first (), second (), and third () wavelength range.
