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.
