Abstract:
1. An organic light emitting diode comprising: a substrate, an organic layer sequence configured to generate electromagnetic radiation during operation, wherein the organic layer sequence is arranged in a central region of the substrate; a metallization is arranged in an edge region of the substrate and designed to make electrical contact with the organic layer sequence; and a separately produced metallic contact structure, which is cohesively and electrically conductively connected to the metallization by a joining process based on ultrasonic technology; wherein the contact structure has a main extension plane arranged parallel to main area of the substrate; and wherein the contact structure is cohesively and electrically conductively connected to the metallization at at least one connecting point, wherein the contact structure has a main structure in which the at least one connecting point is embedded, and wherein the at least one connecting point comprises a material that is different from a material of the main structure.
