Abstract
The invention relates to the operation of illuminants, in particular OLEDs. The invention relates to a method and a measuring instrument for determining the electrical properties of an OLED, the equivalent circuit diagram of which is composed of the parallel connection of an equivalent diode Dand an equivalent capacitance Cas well as an equivalent resistance Rthat is connected in series to said parallel connection. The values for the equivalent resistance Rand the equivalent capacitance Care determined at a different time than are the values for the equivalent diode D.
