Abstract: In various embodiments, an optoelectronic assembly may include at least one organic light emitting diode including a first light emitting diode element and a second light emitting diode element, and an electronic circuit. The first light emitting diode element and the second light emitting diode element are electrically connected in parallel and are deposited monolithically on a common substrate, and the electronic circuit is designed to compare an electric current through the first light emitting diode element that flows during operation with an electric current through the second light emitting diode element that flows during operation and, depending on the comparison, to detect a short circuit of the first light emitting diode element or of the second light emitting diode element and to initiate an electrical switching off of one of the light emitting diode elements and/or of the assembly.

Abstract: A method for producing an organic light-emitting diode and an organic light-emitting diode are disclosed. In an embodiment, the method includes providing a substrate with a continuous application surface, generating multiple adhesion regions on the application surface, the adhesion regions being completely surrounded by the application surface, applying metal nanowires over the entire surface of the application surface, removing the metal nanowires outside of the adhesion regions by a washing process using a solvent such that the remaining metal nanowires completely or partly form a light-permeable electrode of the organic light-emitting diode, and applying an organic layer sequence onto the light-permeable electrode.

Abstract: In one embodiment the organic light-emitting diode includes a substrate having a substrate upper side, an electrically conductive grid structure for a current distribution and an electrically conductive particle layer, which are located at the substrate upper side. The grid structure may be embedded in the particle layer. An organic layer sequence for generating the radiation is located directly on the particle layer. A covering electrode is attached to the organic layer sequence. The particle layer comprises scattering particles having a first average diameter and electrically conductive particles having a smaller second average diameter. The scattering particles are densely packed together with the conductive particles. The particle layer forms, together with the grid structure, a substrate electrode for the organic layer sequence.
