    Abstract: An optoelectronic assembly and method for operating an optoelectronic assembly are provided. In some aspects, the optoelectronic assembly includes an organic light-emitting component, a temperature sensor configured to record a temperature value, and a driver circuit coupled to the organic light-emitting component and the temperature sensor. The driver circuit is configured to apply an AC voltage to the organic light-emitting component when the organic light-emitting component is switched on, and if the recorded temperature value is less than a predetermined temperature threshold value, where the AC voltage is, at least, temporarily less than an instantaneous threshold voltage of the organic light-emitting component. The driver circuit is also configured to apply a DC voltage to the organic light-emitting component if a measurement value is greater than or equal to a predetermined threshold value, where the DC voltage is greater than the instantaneous threshold voltage of the organic light-emitting component.

    Abstract: A method for producing an organic light-emitting component is disclosed with providing a carrier, forming a first electrode over the carrier, forming an organic functional layer structure over the first electrode, and forming a second electrode over the functional layer structure. The first and second electrodes and the functional layer structure overlap in an optically active region which extends in the lateral direction and is embodied to generate light. In an optically inactive region extending over the carrier in the lateral direction, an electrically conductive contact layer is formed over the carrier, so that it is in direct physical and electrical contact with the first electrode and/or the second electrode. A first contact section and at least one second contact section of the layer are separated from one another by a lithographic process, so that they are electrically insulated from one another. The layer is structured by a laser beam.

    Abstract: An optoelectronic assembly and method for operating an optoelectronic assembly are provided herein. The optoelectronic assembly may include an organic light-emitting component, a temperature sensor for recording a temperature value, and a controller coupled to the organic light-emitting component and to the temperature sensor. The controller may be configured to apply an alternating current (AC) voltage to the organic light-emitting component when the organic light-emitting component is switched on, and if the recorded temperature value is less than a predetermined temperature threshold value, where the AC voltage may, at least, temporarily less than an instantaneous threshold voltage of the organic light-emitting component. The controller may also be configured to apply a direct current (DC) voltage to the organic light-emitting component if a measurement value is greater than or equal to a predetermined threshold value, where the DC voltage is greater than the instantaneous threshold voltage of the organic light-emitting component.

    Abstract: A method can be used for operating an organic light-emitting component. The organic light-emitting component has a first electrode and a second electrode, between which an organic functional layer stack with at least one organic light-emitting layer is arranged. The first and second electrodes and the organic functional layer stack have a large area. Electrical contact is made with the first electrode via at least two electrical connection elements in the peripheral regions, in which different electric voltages are applied to the at least two electrical connection elements and the different electric voltages vary over time. A lighting device for implementing the method is also specified.
