Radiation-emitting arrangement
View Patent ↗A radiation-emitting arrangement comprises, in particular, a carrier element ( 1 ) having an at least partly non-transparent main surface ( 10 ) and arranged on the carrier element ( 1 ), an organic radiation-emitting component ( 2 ) having an organic layer sequence ( 23 ) with an active region between an at least partly transparent first electrode ( 21 ) and an at least partly transparent second electrode ( 22 ). The active region ( 29 ) is suitable for generating electromagnetic radiation ( 91, 93 ) in a switched-on operating state. The radiation-emitting arrangement has a radiation exit area ( 3 ) for emitting the electromagnetic radiation ( 92, 93 ) on that side of the organic radiation-emitting component ( 2 ) which faces away from the carrier element. ( 1 ) The at least partly non-transparent main surface ( 10 ) of the carrier element ( 1 ) is perceptible by an external observer through the radiation exit area ( 3 ) in a switched-off operating state of the organic radiation-emitting component ( 2 ).

wherein the radiation-emitting arrangement has a radiation exit area for emitting the electromagnetic radiation on that side of the organic radiation-emitting component which faces away from the carrier element;
wherein the at least partly non-transparent main surface of the carrier element is perceptible by an external observer through the radiation exit area in a switched-off operating state of the organic radiation-emitting component;
wherein the organic radiation-emitting component has an emission characteristic of the electromagnetic radiation generated in the active region with a first intensity in a direction of the carrier element and a second intensity in a direction of the radiation exit area;
wherein the second intensity is greater than the first intensity;
wherein the first electrode is arranged on that side of the organic layer sequence which faces the carrier element;
wherein the first electrode has a lower transmittivity than the second electrode;
wherein the at least partly non-transparent main surface of the carrier element is imperceptible to the external observer through the radiation exit area in the switched-on operating state; and
wherein one of the first and the second electrodes is an anode and the other is a cathode.
