Embodiment Construction

[0046] In the exemplary embodiments and figures, identical or identically acting components are provided with the same reference symbols. The elements shown and their dimensional relationships to one another are in principle not to be regarded as to scale. Rather, individual elements such as layers, components, components and regions can be shown with exaggerated thickness or exaggerated large dimensions for better visibility and / or for better understanding.

[0047] exist figure 1 An example of an organic electroluminescent component having a first organic functional layer stack 1 and a second organic functional layer stack 2 is shown in FIG. A metal layer 3 is arranged between the two organic functional layer stacks 1 and 2 .

[0048] The organic electroluminescent component also has a substrate 4 on which the organic functional layer stacks 1 and 2 and the metal layer 3 are arranged between a first electrode 5 and a second electrode 6 for electrically contacting the funct...

Abstract

The invention relates to an organic electroluminescent component having a first organic functional stack (1), which has a first electroluminescent layer (11) and at least one n-doped organic layer (12), and a second organic functional stack (2), which has a second electroluminescent layer (21) and at least one p-doped organic layer (23), wherein the n-doped and the p-doped organic layers (12, 23) are arranged between the first and second electroluminescent layers (11, 21) and a metal layer (3) is arranged therebetween, directly adjacent to the n-doped and the p-doped organic layers (12, 23).

Description

technical field [0001] The invention provides an organic electroluminescent device. Background technique [0002] Organic light-emitting diodes (OLEDs) are known which emit on one side during operation. In this case, one side of the OLED is reflective, while the other side, through which the light is emitted, is transparent. [0003] Furthermore, OLEDs are known which emit on both sides during operation and which are transparent in the off state. The light generated in the electroluminescent region is generally emitted uniformly in the direction towards both sides, so that the emission properties on both sides cannot be adjusted independently of one another. [0004] In order to produce OLEDs on both sides with emission properties that can be adjusted separately from one another, usually two single-sided emitting OLEDs are arranged with their reflective sides one above the other and are operated independently of one another. Contents of the invention [0005] At least s...
