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.
