Abstract
Official abstract text for this publication.
In at least one embodiment of the organic light-emitting diode ( 1 ), this comprises a mirror ( 3 ) and an organic layer sequence ( 4 ). The organic layer sequence ( 4 ) contains a first active layer ( 41 ) for producing first radiation and at least two second active layers ( 42, 43 ) for producing second radiation. The active layers ( 41, 42, 43 ) are arranged one above the other in a main direction (x) away from the mirror ( 3 ). A charge generation layer ( 45 ) is located in each case between two adjacent active layers ( 41, 42, 43 ). The second active layers ( 42, 43 ) each have the same at least two radiation active organic materials. The first active layer ( 41 ) has a radiation active organic material which is different therefrom.
First claim
