Abstract:
In order to improve the decoupling efficiency in a top-emitting OLED a top-emitting electroluminescent component (100) is suggested comprising a substrate, a first electrode (120) nearest to the substrate, a second electrode (14) located at a distance from the substrate, and at least one light-emitting organic layer (130) arranged between both electrodes, the emitted light being transmitted through the second electrode. The component in accordance with the invention is distinguished by an additional layer (150) facing away from the at least one organic layer is arranged on the side of the second electrode, which additional layer comprises optically effective light-emitting heterogeneities (151, 152, 153), especially in the form of scatter centers, the degree of transmission of the additional layer of the emitted light being greater than 0.6. This additional layer can be applied by various wet-chemical processes and vacuum methods, the inhomogeneities being introduced into and/or applied onto the decoupling additional layer during or after the application process. Furthermore, the invention also relates to a method for producing such a component.
