[0045] figure 1 A schematic illustration of an arrangement with a microcontroller 1 and a pulse width controller 2 whose output is coupled to an organic light emitting diode 3 is shown. The microcontroller 1 and the pulse width controller 2 form a driver circuit 4 with which the pulsed current is generated, the driver circuit 4 being coupled to the organic light emitting diode 3 during operation. according to figure 1 As illustrated in , the feedback of the pulse width controller 2 to the output of the microcontroller 1 takes place via the feedback line 5 . Feedback is used for measurements, which can be used in order to determine capacitance or instantaneous current.
[0046] figure 2 shows where the amplification by the measurement circuit 6 comes from figure 1 Schematic arrangement of the arrangement of , using the measuring circuit 6 , the average current is measured at the organic light-emitting diode 3 during operation, since the average current is shunted via the r...
