An organic optoelectronic component includes an organic functional layer stack between a first electrode and a second electrode including a light-emitting layer formed to emit a radiation during operation of the component, and a coupling-out layer arranged above the first electrode and/or the second electrode which is in a beam path of the radiation of the light-emitting layer, wherein the coupling-out layer includes a structured layer and a planarization layer arranged thereabove and the structured layer has a structured surface structured at least in places, the planarization layer planarizes the structured surface of the structured layer, and a difference in the refractive indices of the structured layer and the planarization layer is smaller than 0.3 at least in places.

An organic light-emitting diode includes a carrier; at least two electrodes; an organic layer sequence having at least one active zone that generates light; and light-opaque visual protection layers that have no influence on an emission characteristic of the organic layer sequence and the organic light-emitting diode, one of which is located directly on the carrier, the organic layer sequence is located between the two electrodes and one of the electrodes is attached directly to the carrier, the visual protection layer, viewed in a plan view, completely surrounds the organic layer sequence, at least one of the electrodes is provided with a structuring in a region adjacent to the organic layer sequence in a plan view, in a plan view, the structuring is located completely beside the organic layer sequence, and the structuring is hidden by the visual protection layer for a viewer from outside the organic light-emitting diode.

A method of preventing an analysis of the material composition of an organic optoelectronic component includes: A) providing an organic optoelectronic component having a functional component part and a camouflage layer, and B) determining an overall analysis spectrum of the organic optoelectronic component by IR or X-ray radiation, wherein the overall analysis spectrum is composed of a first analysis spectrum of the functional component part and a second analysis spectrum of the camouflage layer, and determination of the first and/or second analysis spectrum from the overall analysis spectrum is made more difficult or prevented so that, due to the camouflage layer, determination of the material composition of the functional component part is made difficult or prevented.
