Description

The invention relates to an organic, light-emitting component and to a method for producing the organic, light-emitting component.

Organic, light-emitting components with an organic light emitting diode as the emission unit find due to their low power consumption, high performance and design options increasingly widespread application in general lighting or in the automotive industry, for example as a light source. For customers in the automotive industry, the visual impression and the high value of the components used are in the focus. For example, emphasis is placed on a substantially flawless appearance.

As in 7 As illustrated, an organic light emitting device typically includes a substrate having a substrate 702 and an inorganic insulating layer 703 a first electrode disposed on the carrier 704 , one on the first electrode 704 arranged, organic, light-emitting layer 706 for emitting an electromagnetic radiation, one on the organic, light-emitting layer 706 arranged, second electrode 708 , one on the second electrode 708 arranged thin-film encapsulation 710 and metal contacts 714 for external, electrical contacting of the organic, light-emitting component. Here are the metal contacts 714 in an optically inactive area 740 of the organic, light-emitting component and each of one of the electrodes 704 . 708 by means of an electrically insulating resist structure 712 isolated. In other words: a metal contact 714 is with only one of the electrodes 704 . 708 directly electrically connected and is from the other electrode 704 . 708 by means of the resist structure 712 electrically isolated. The organic, light-emitting component can be designed as a top emitter and / or bottom emitter. In a bottom emitter, the electromagnetic radiation is from the optically active region 720 emitted by the carrier. In a top emitter, the electromagnetic radiation is through the Dünnfilmverkapselung 710 emitted and not by the carrier.

In conventional bottom emitter type organic light emitting devices, the appearance is determined by the metallization directly applied to the (transparent) support. Structures such as (outgoing) geometric edges of the organic, light-emitting layer, the geometric edge of the second electrode, etc. can be easily laminated. For reasons of reliability, a top emitter device concept is used in the flexible, organic, light-emitting components currently under development. However, this has disadvantages in terms of the optical impression of the organic, light-emitting device 700 with itself, for example due to being in a transition area 730 arranged edges or edges of the organic, light-emitting layer, the electrodes, the metal contacts and the thin-film encapsulation, wherein the transition region in a plan view of a portion of the layers of the optically active region 720 and a part of the layers of the optically inactive region 740 having. In this case, the organic, light-emitting component 700 at least five externally visible transitions between the different layer structures, as in 7 is illustrated by the vertical lines. Further, due to these transitions, it is not apparent to the consumer where exactly the light-emitting surface in the organic light-emitting device is located 700 located. This is of relevance, for example, if the organic, light-emitting component is to be arranged centrally in a holder, for example in order to maximize the light-emitting surface or to align it with respect to further optical components.

The object of the invention is to provide an organic light-emitting component which has an appearance in which the individual transitions of the layers of the organic, light-emitting component-forming layer structures are substantially invisible. Alternatively or additionally, a position mark of the boundaries of the light-emitting surface is to be realized.

In various embodiments, an organic, light emitting device is provided. The organic, light-emitting component has an optically active region with an optical property and an optically inactive region, which is formed laterally next to the optically active region. The optically active region has an organic, light-emitting layer. The optically inactive region is free of the organic, light-emitting layer. Furthermore, the organic, light-emitting component has, for example, a thin-film encapsulation, a carrier and a plurality of layers. In this case, the multiple layers are formed between the thin-film encapsulation and the carrier. In addition, the plurality of layers are arranged, for example, in the optically active region and partially in the optically inactive region. Furthermore, the organic, light-emitting component has a transition region with at least one contiguous region. The at least one contiguous region comprises a part of the optically active region and a part of the optically inactive region. It has the Transition region, for example, at least partially on the multiple layers. The organic, light emitting device is operable in at least a first operating mode and a second operating mode. The transition region has an optically opaque contrast structure in the at least one contiguous region. In this case, the contrast structure has a further optical property, wherein the further optical property is independent of the first operating mode and the second operating mode different from the optical property of the optically active region.

The contrast structure of the organic light-emitting device enables the visibility of the transitions between the various layers (structures) forming the organic light-emitting device to be reduced or avoided. This leads to an improved appearance of the organic, light-emitting component, for example to a structure of the organic, light-emitting component which appears to be simpler in plan view. Furthermore, the contrast structure of the organic, light-emitting component can act or serve as a position mark, for example for the insertion of the organic, light-emitting component in a holder. This makes it possible to easily locate the light-emitting surface of the organic light-emitting component and to arrange it appropriately aligned in the holder.

In the context of this description, the term "contrast structure" is understood to mean a structure which has an optical property which gives an optical difference to the region in which the contrast structure is arranged, to the regions which are free of contrast structure.

The term "optical property" with respect to the optically active region and the contrast structure is referred to in this specification as the transmission, absorption, emission and / or reflection of electromagnetic radiation emitted by the organic, light-emitting component electromagnetic radiation or on the organic, light-emitting Component incident, component-external electromagnetic radiation understood. The electromagnetic radiation is for example an ultraviolet radiation, a visible light or an infrared radiation.

The contrast structure may comprise a fluorescent or phosphorescent material, wherein by means of the emission of this material the contrast in the optical property is formed in the operating modes. In other words, the different optical property, for example an optical contrast, can only be realized under certain conditions, for example only when the contrast structure is irradiated with a predetermined electromagnetic radiation. The different optical properties can thus be visible only under given conditions in the operating modes.

For example, one of the operation modes is an OFF state and the other operation mode is an ON state (light-emitting state).

In this case, the incident light is the light which is incident on the contrast structure and which is transmitted, absorbed or reflected by the contrast structure (for example Mie scattering).

For example, the transition region optically includes the optically active region. Frame may be formed as a closed polyline, for example in the form of a circle, a quadrilateral, a polygon or a Polygonenzuges. Furthermore, the contrast structure can be designed in the shape of a frame and surround the optically active region in the form of a frame. The frame can be a closed polyline or can be implemented as a plurality of individual regions along a polyline, for example as a dashed line.

This allows a simple approximation of a geometric center of the optically active region of the organic light-emitting component, since the transition region can serve as a reference point.

In yet another embodiment, the contrast structure extends laterally substantially completely into the transition region. In other words, the contrast structure is formed over the entire width of the transition region.

The optical property of the optically active region may change depending on the operating mode being operated. Several modes of operation may have overlapping characteristics, for example, two modes of operation may emit light of substantially the same luminance, the light having different color locations.

This allows a contrast structure 116 which has a dark or black appearance or is black. For example, the carbon compound comprises or is formed from graphene, graphite, carbon nanotubes or fullerenes or mixtures thereof. For example, the light-absorbing material substantially comprises graphite. The light-absorbing material may have traces of other materials due to impurities in the starting materials in forming the contrast structure 116 are present in the light-absorbing material.
