A circuit arrangement for operating an OLED may include a current source to supply the OLED with power; an OLED voltage measuring device configured to provide at its output a signal which is correlated with the voltage dropping across the OLED; an evaluation device configured to provide at its output a first signal if the voltage dropping across the OLED lies above a specifiable threshold value, and to provide a second signal if the voltage dropping across the OLED lies below the specifiable threshold value; an electronic switch having a reference electrode, a working electrode and a control electrode; and at least one ohmic resistor; wherein the series connection of the at least one ohmic resistor and the working electrode-reference electrode section of the electronic switch is connected in parallel with the OLED.
