Abstract

An organic light-emitting component device comprising a first and second organic light-emitting component, a temperature detecting device configured for detecting at least one temperature, and a control unit coupled to the temperature detecting device and configured to operate the first and second component. The control unit is such that a first or second operating parameter of the first or second component, respectively, is changed, wherein the temperature detecting device comprises a first and second temperature detecting device. The first and second temperature detecting devices are designed for detecting a first and second temperature of the first and second component, respectively. The control unit is configured to change the first or second operating parameter depending on the difference between the first and second temperature, wherein the first or second operating parameter is changed such that the same temperature is established at the first and second component.
