Problems solved by technology

[0005] On the one hand, the visual control when installing the OLED is error-prone due to the extremely high risk of confusion and on the other hand, it is combined with a high time consumption during disassembly and installation.
[0006] However, when using components whose polarity cannot be exchanged, for example due to the use of flexible strips with pins, additional costs are required and additional structural measures of the components are required in the back-end process.

Embodiment Construction

[0035] In the exemplary embodiments and figures, identical, similar or identically acting elements are each provided with the same reference signs. The illustrated elements and their size relationships are not to be regarded as to scale with respect to each other, rather the individual elements, such as layers, components, devices and regions, are for better visibility and / or for better Understanding can be shown exaggeratedly.

[0036] exist figure 1 The schematic structure of an organic light-emitting element 100 , which is formed as an organic light-emitting diode (OLED), is shown according to an exemplary embodiment.

[0037] The organic light-emitting element 100 , which can also be referred to below as OLED 100 , has a substrate 101 , on which an organic functional layer stack 103 is arranged between electrodes 102 and 104 , said organic functional layer stack having at least one organic light-emitting layer. At least one of the electrodes 102 , 104 is designed to be ...

Abstract

The invention relates to an organic optoelectronic component comprising an organic light emitting element (100) and an organic protective diode element (200), said organic light emitting element (100) comprises an organic functional layer stack (103) having at least one organic light emitting layer between two electrodes (102, 104), and the organic protective diode element (200) comprises an organic functional layer stack (203) having an organic pn-junction between two electrodes (202, 204) and is arranged on a common substrate (101) in laterally adjacent surface areas with the organic light emitting element (100).

Description

technical field [0001] An organic optoelectronic device is proposed. [0002] This application claims priority from German patent application 10 2012 222 772.5, the disclosure content of which is hereby incorporated by reference. Background technique [0003] Organic Light Emitting Diodes (OLEDs) must be connected to a DC voltage or DC current with the correct polarization for operation. In the event of incorrect polarization, there is a risk of electrical breakdown, resulting in destruction of the OLED, for example due to melting of the organic material at weak points. [0004] In the case of a series connection of several OLEDs polarized symmetrically in the structure, it is not possible to observe which OLED is incorrectly loaded with a constant voltage supply to reverse polarization in one of the OLEDs due to at least one pn junction being blocked . [0005] On the one hand, visual control during the installation of OLEDs is error-prone due to the extremely high risk ...
