Abstract

See full text

The invention relates to a method for operating an organic light emitting component (1), in particular organic light emitting diode (OLED), and an organic light emitting component (1) with an organic layer (1c) comprising a plurality of different emitter materials, which emit light of different colours, and an electrode arrangement (1a, 1b) for applying electric control pulses to the organic layer (1c), the method having the following steps: operating the organic light emitting component (1) with the help of the electric control pulses in a pulsed operating mode with an operating frequency of at least about 25 Hz; at least partially compensating an ageing induced varying colour change of the light emitted from the organic layer (1c) during the course of the pulsed operation by recording at least one operating parameter characterizing the running pulsed operation of the organic light emitting component (1) and for which a dependence relationship to the ageing induced varying colour change is known at least approximately, and by adjusting a pulse height of the electrical control pulses according to the at least one recorded operating parameter and the ageing induced varying colour change; and regulating a predetermined luminance of the light emitted from the organic layer (1c) during the course of the pulsed operation by adjusting a pulse length of the electric control pulses for regulating the predetermined luminance of the light emitted from the organic layer (1c).
