Organic optoelectronic component and method for operating the organic optoelectronic component

This patent application claims the priority of German Patent Application 10 2012 220 049.5, the disclosure of which is hereby incorporated by reference. An organic optoelectronic component and a method for operating the organic optoelectronic component are specified.

Area light sources such as an organic light

Emissive diode (OLED) are subject to aging processes, through which, depending on the OLED layer structure and processing, the luminance in the sum decreases with time. The decrease in the luminance can be increased for example by

Temperatures that occur during operation and can damage the organic materials.

To the luminance of a light source such as a

To keep surface light source constant over time, the light emitted by the light source, for example, by means of manual dimming or by means of an electronic circuit that controls the light source based on a measurement signal of one or more externally connected sensors, can be controlled. For example, photodiodes, photoconductors, phototransistors or photothyristors can be used as external sensors for detecting the entire radiant power emitted by the light source at a preselected location, which via an external interconnection or wiring is part of a control of the luminous source can. However, such a possibility requires

usually a high effort and causes additional costs. A manual dimming, however, allows only an inaccurate vote on actually existing

Lighting conditions and causes an unnecessary

Waste of energy and possibly wrong

Lighting conditions.

Since the known control options of

Area light sources a high Verschaltungsaufwand

or can not be automated, an automatic readjustment of the luminance is not possible without considerable additional effort.

At least one object of certain embodiments is to provide an organic optoelectronic device. At least one more task of certain

Embodiments are to specify a method for operating an organic optoelectronic component.

These tasks are covered by an object and a

Method solved according to the independent claims. Advantageous embodiments and further developments of

Subject matter and the procedure are in the dependent

Claims and continue to go from the

following description and the drawings.

In accordance with at least one embodiment, an organic optoelectronic component has at least one organic light-emitting element which has an organic light-emitting element

functional layer stack with at least one organic light-emitting layer between two electrodes

having. In particular, this is at least one organic Light-emitting element as an organic light-emitting diode (OLED) is formed, which can emit visible light through at least one of the electrodes during operation. For this purpose, at least one of the electrodes is transparent.

In this case, "transparent" refers to a layer which is permeable to visible light, whereby the transparent layer may be transparent or at least partially light-scattering and / or partially absorbing light, so that a layer designated as transparent, for example, also diffuse or milky

can be translucent. Particularly preferred is a layer designated here as transparent as possible

permeable to visible light that is formed

in particular the absorption of in organic light

emitting element is as low as possible.

For example, a transparent electrode may be or may comprise a transparent conductive oxide (TCO), graphene, a transparent metal or metallic network structures, and the other of the two electrodes, between which the

organic functional layer stack is located of the organic light-emitting element, can be reflective

be formed and, for example, have a metal. Alternatively, both electrodes may be transparent. In this case, the organic light-emitting element may be formed in particular as a transparent OLED.

The organic optoelectronic component furthermore has at least one organic light detecting element, having at least one organic light detecting layer. In particular, the at least one organic light detecting element may be configured to convert light incident on the at least one organic light detecting layer into an electrically measurable signal, such as voltage, current or electrical resistance.

Furthermore, the organic optoelectronic component has a common substrate for the at least one organic light-emitting element and the at least one organic light-detecting element, which are arranged in particular on the common substrate in laterally adjacent surface regions. The organic light-emitting element and the organic light-detecting element are further arranged in a same plane by the common arrangement on the same substrate in laterally adjacent surface areas, wherein the organic light-emitting element and the organic light detecting element each directly adjacent to the substrate.

The common substrate may in particular be the only one

Substrate of the organic optoelectronic device be. In this case, the functional layer stacks and the electrodes of the organic light-emitting and light-detecting elements of the organic optoelectronic component are applied successively or simultaneously, in particular on the common substrate, so that the common substrate is the substrate which is the substrate

Preparation of the organic light-emitting and light-detecting elements is required and provided. In other words, the organic light-emitting and light-detecting elements do not become on their own substrates and then placed on the common substrate but fabricated on the common substrate. Thus, in particular, no further substrate is arranged between the common substrate and the organic functional layers of the organic light-emitting and light-detecting elements.

The term "lateral" here and in the following denotes a direction parallel to the main extension plane of the common substrate, so that a lateral direction is, for example, perpendicular to the stacking direction of the electrodes and the

directed organic functional layer stack of at least one organic light-emitting element. Furthermore, the at least one organic light

detecting layer of the at least one organic light detecting element disposed between two non-transparent layers, the at least one light

Shadow the detecting layer from ambient light. To an effective shading of at least one organic

Light detecting layer of the at least one organic light detecting element from ambient light

reach, that is at least one organic light

detecting layer is preferably arranged in the stacking direction between the two non-transparent layers, so that in the stacking direction, a non-transparent layer below and a non-transparent layer over the at least one

organic light detecting layer is arranged. As "ambient light", hereinafter light,

in particular visible light, designated, which can meet from outside on the at least one organic light detecting element, that is not within the organic Optoelectronic component is passed by internal stray and / or Lichtleitungseffekte from at least one light emitting element to at least one light detecting element. In particular, ambient light can also be a light which has spectral components which correspond to the absorption spectrum of the at least one organic light-detecting layer. In other words, the non-transparent layers are in particular arranged such that they expose the at least one organic light detecting layer to at least that part of the

Abschatten ambient light, the absorption spectrum of the at least one organic light detecting layer and further the absorption spectrum of the at least one

corresponds to organic light detecting element.

Characterized in that the at least one light-detecting layer through the two non-transparent layers before

Ambient light is shaded, it is in particular achieved that the at least one organic light detecting layer reaching proportion of ambient light on the at least one light detecting element from the outside

is irradiated, as compared with an organic light detecting element without the two non-transparent layers is reduced. The shading preferably effects a reduction of greater than or equal to 90%, and particularly preferably greater than or equal to 99% or even greater than or equal to 99.9% of the ambient light irradiated from outside onto the at least one organic light detecting element. In other words, this means that less than 10% and preferably less than 1% of the ambient light is radiated onto the at least one organic light-detecting layer. In particular, the non-transparent layers may also be completely impermeable to ambient light and in particular the spectral component of the ambient light, which corresponds to the absorption spectrum of the at least one organic light detecting element.

Furthermore, these are at least one organic light

emitting element and the at least one organic light detecting element disposed on the same side of the common substrate. With particular regard to further optoelectronic elements, that is to say further light-emitting or light-detecting elements which can be arranged on the common substrate, the at least one organic light-detecting element can be directly adjacent to the at least one organic light

That is, in the lateral direction between the at least one organic light detecting element and the at least one organic light emitting element there are no further organic light emitting or light detecting elements.

According to a further embodiment, the at least one organic light-emitting element is adapted to light on a radiation side of the organic

to radiate optoelectronic component. A

Radiating side, which designates that side or those sides on which or on which the organic

optoelectronic component emits light, can

For example, be formed by the side on which viewed from the at least one organic light-emitting layer of the at least one organic light-emitting element, the common substrate. In this case, in which the common substrate is preferably transparent, the at least one organic light can emitting element as well as the organic

Optoelectronic device may be referred to as a so-called bottom emitter. Furthermore, it is also possible for a radiation side, viewed from the at least one organic light-emitting layer, to rest on the side of the organic one opposite the common substrate

Optoelectronic component is arranged. In this case, the at least one organic light-emitting element and also the organic optoelectronic component can be designed as a so-called top emitter. If the organic optoelectronic component is simultaneously designed as a bottom emitter and as a top emitter, it may preferably be a transparent organic optoelectronic component having two

Abstrahlseiten be formed.

According to a further embodiment, the at least one organic light detecting element is organic

Photodiode formed and used. The organic

In particular, the photodiode may have an organic functional layer stack between two electrodes, wherein the organic functional layer stack as the organic light detecting layer of the organic light detecting element has at least one pn junction for generating

Containing charge carriers. For example, the organic photodiode may have the same structure as the at least one organic light emitting element with respect to the electrodes and the organic functional layer stack

and inversely to the at least one organic light emitting element, that is with opposite

electrical polarity, operated, which may allow the production of the organic

Optoelectronic device compared to a

only light-emitting device none or only low additional costs. Alternatively, the organic photodiode may have other materials and / or other layer structures with respect to the electrodes and / or the organic functional layer stack compared to the organic light emitting element, which may require additional manufacturing effort, but also sensitivity the at least one organic light detecting element can be specifically adapted.

According to another embodiment, the at least one organic light detecting element is organic

Photoconductor formed and usable with an organic photoconductive material as an organic light-detecting layer, which upon irradiation of light electric

 Charges generated. Organic photoconductive materials may for example be formed in one layer on an electrically conductive layer, for example an electrode. Furthermore, organic photoconductive materials

For example, at least two layers with at least one organic charge carrier generating layer and an organic charge carrier transporting layer

be educated. Moreover, an organic light detecting element configured as an organic photoconductor may have the same structure as the at least one organic light emitting element.

Depending on the materials and structure of the at least one

organic light detecting element, this can also be constructed simultaneously as a photoconductor and photodiode. Such an organic light detecting element may be provided with an electrical bias as a photodiode and without

electrical bias can be used as a photoconductor. Furthermore, depending on the materials used and structure and the electrical resistance of at least one

be measured organic light detecting element, so that the at least one organic light detecting

Element can be designed and used as an organic photoresistor.

In particular, it may be advantageous, as described above, if the at least one organic light detecting

Element and the at least one organic light-emitting element have an identical structure. Furthermore, it may also be possible that the organic light detecting element only n- or p-conductive layers or a

Has optoelectronic layer and this with the

corresponding layers of the organic light-emitting element are the same.

The at least one organic light emitting element and the at least one organic light detecting element are preferably formed electrically separated from each other with respect to their respective electrodes and organic functional layers on the substrate. In other words, the at least one organic light detecting element covers a surface area on the common substrate, which is spatially separated from the surface area that the

covering at least one organic light emitting element on the common substrate. Alternatively, it may, depending on the electrical control of the organic light

emitting and the organic light detecting

Elements may also be possible for these to be a common one

Have electrode. In accordance with a further embodiment, the at least one organic light-detecting element is smaller than the at least one organic light-emitting element with respect to its area occupation on the common substrate

educated. In particular, the at least one organic light detecting element on the common substrate may cover an area that is less than or equal to ten percent, or less than or equal to five percent, or less than or equal to one percent of the area of the at least one organic light emitting element the common substrate is covered. In other words, the

predominantly part of the common substrate with the at least one organic light-emitting element or

optionally be covered with a plurality of organic light emitting elements, while the at least one organic light detecting element or

optionally a plurality of organic light

Detecting elements occupy only a small area, so that the organic optoelectronic

Component in operation has a luminous surface, which may correspond substantially to the total area of the common substrate.

According to a further embodiment, the organic optoelectronic component is set up such that a part of the light generated in operation in the at least one organic light emitting element internally in the organic optoelectronic component for at least one organic light detecting element and in particular for at least one organic light detecting layer becomes. Such an internal light pipe from the at least one organic light emitting element to the at least one organic light detecting element can for example, by waveguide effects and / or by scattering effects within the organic optoelectronic device. An internal light pipe can

for example, by an internal scattering layer

to be influenced.

For example, the common substrate can form a light guide, the light from the at least one organic light emitting element internally in the organic

Opto-electronic device for at least one organic light detecting element passes. The common substrate is particularly preferably transparent in this case

formed and may for example comprise glass and / or a transparent plastic or be it.

For example, the common substrate in the form of a glass plate or glass layer or in the form of a

Plastic plate, plastic layer or plastic film or in the form of a glass-plastic laminate may be formed with at least one glass layer and at least one plastic layer.

Does that detect at least one organic light detector

Element between the at least one organic light detecting layer and the common substrate to an electrode, it is also transparent in the case of a light pipe in the substrate through or has at least one light-transmissive region. This may mean that the electrode, for example, as

Ring contact formed or formed by a transparent material. As "ring contact", any shape of an electrode is here and hereinafter referred to, which is one of

Has electrode material in the lateral direction completely or even partially enclosed opening. Especially can also fall a for example U-shaped electrode under the term ring contact.

As an alternative or in addition to the common substrate as an internal light guide, other layers of the organic optoelectronic component can also serve as a light guide between the organic light emitting element and the organic light detecting element.

For example, an encapsulation and / or a

Cover, which is arranged above the organic layers seen from the common substrate, an internal

Light guide from the organic light emitting element to the organic light detecting element effect. A

Layer or an element of the organic optoelectronic component, which serves as an internal light guide is

particularly preferably transparent.

 In particular, light pipe effects can also be caused by suitable refractive index differences between individual layers or elements of the organic optoelectronic component. By a suitable choice of

 Refractive index differences and / or the transparency of

Layers and elements of the organic optoelectronic component which are to contribute to the light conduction, the proportion of the organic light emitting element to the organic light detecting element internally conducted light can be adjusted. Furthermore, one or more internal stray or outcoupling layers, ie

 Decoupling layers between the substrate and the substrate-facing electrode influence the internal light pipe.

According to a further embodiment, the organic optoelectronic component is set up such that in operation in the at least one light-emitting layer of the At least one organic light emitting element generated light is irradiated internally in the organic optoelectronic component directly to the at least one organic light detecting layer of the at least one organic light detecting element. That can

in particular, that between the at least one organic light emitting layer and the at least one organic light detecting layer no

Layers or elements are present which shade the at least one organic light detecting layer completely from the organic light emitting layer.

According to at least one embodiment, a method for operating the organic optoelectronic component comprises an electronic component, for example a controllable current and / or voltage source, which detects the light detected by the at least one organic light internally in the optoelectronic component of the at least one light has emitting element to the at least one light detecting element directed light, measures and that the at least one organic light

regulates emitting element as a function of the measurement. That the electronic component of the at least one

organic light detecting element detects detected light, in particular, means that the electronic

Component measures the electronically measurable signal of at least one organic light detecting element.

For example, the electronic component, so for example a controllable power and / or

Voltage source, at least partially integrated into the organic optoelectronic component. In other words, the controllable current and / or voltage source be formed by an electronic component, as a hybrid or monolithic electronic circuit

is formed, which may for example be integrated in the common substrate or in the form of additional functional layers on the common substrate

can be trained. For example, the common substrate for this purpose at least partially an integrated

Circuit based on a semiconductor material, such as silicon, and / or have printed electronics.

Alternatively, it may also be possible for the electronic component, that is to say for example the controllable current and / or voltage source, to be designed as an external electronic component which is connected to the organic optoelectronic component via suitable electrical connections such as conductor tracks and / or wire connections ,

Furthermore, it may also be possible to connect the at least one organic light-emitting element and the at least one organic light-detecting element separately from one another. For this purpose, the at least one organic light-emitting element with an electronic

Component be connected in the form of a current and / or voltage source, while the at least one organic light detecting element with an electronic component in the form of a current and / or voltage and / or

Resistance measuring device is connected.

The features described above and below and

Embodiments equally apply to the organic optoelectronic component and to the method for operating the organic optoelectronic component. Due to the monolithic integration of the at least one organic light detecting element, which may have, for example, the same layer structure as the at least one organic light emitting element on a preferably small, separated surface area of the common substrate, in addition to at least in the organic optoelectronic component described here, at least an organic light emitting element, a sensor element can be integrated. Depending on the strength of the light incident on the organic light detecting element, which is formed by that part of the light generated by the at least one organic light emitting element, which is internally in the optoelectronic component of the light

is passed to the light detecting element emitting an electrically measurable signal such as a

 Photograph voltage, a photocurrent or a change in resistance generates, the higher the higher the incident light intensity. The electrically measurable signal of the at least one organic light detecting element can be further processed in an electronic circuit which can be formed by an external electronic component or which can form a part of the organic optoelectronic component as a monolithic element. By the electronic circuit, in turn, the organic light emitting element can be controlled so that the luminosity at the location of the at least one organic light detecting element can be kept constant. The area of the at least one organic light detecting element can be adjusted so that a sufficiently stable electrically measurable signal can be generated during operation without being unstable

Feedback an instability of the light source, so the at least one organic light-emitting element is caused.

In the case of the organic optoelectronic component described here, it can be advantageously possible to achieve an exact automatic readjustment of the emitted light intensity of the organic light-emitting element without an external sensor, which is particularly the case

Circuit complexity compared to known solutions

can significantly reduce. In particular, the light emitting diode at the point of origin of the light is independent of

 Aging properties of the light source kept automatically constant, for example, can be exploited that the at least one organic light detecting element ages much slower than the at least one organic light-emitting element, in particular the organic materials of the at least one organic light

Detecting element less loaded, in particular less thermally loaded, are.

According to a further embodiment, at least one of the two non-transparent layers is formed by a nontransparent cover layer. The non-transparent cover layer may be, for example, a non-transparent plastic or a non-transparent metal,

For example, aluminum or other below, for example, in connection with electrodes described metal, have or be from. Particularly preferably, one of the two non-transparent layers can be formed by a non-transparent covering layer, which is arranged on one side of the common substrate facing away from the at least one organic light-detecting layer. The non-transparent cover layer can in this case the - IS

Cover surface area on which there is at least one organic light detecting element on the opposite side of the substrate. Furthermore, it is also possible to arrange a non-transparent covering layer between the substrate and the at least one organic light-detecting layer as a nontransparent layer.

According to another embodiment, one of the two non-transparent layers is formed by the common substrate. For this purpose, the common substrate can have a non-transparent material, for example a non-transparent plastic and / or a nontransparent metal, at least in the region of the at least one organic light detecting element. If the at least one organic light-emitting element is designed as a so-called top emitter and emits light in the direction away from the substrate, the entire common substrate can also be made non-transparent. For example, the common substrate, in regions or over the entire surface of a metal layer, for example a

Steel foil, include or be. Furthermore, graphite or graphene are also conceivable.

According to a further embodiment, at least one of the non-transparent layers is formed by an electrode of the at least one organic light detecting element. Particularly preferred is a formed as a non-transparent layer ^¬ electrode may be disposed on the side remote from the common substrate side of at least one organic light-detecting layer. Alternatively or additionally, the at least one light-detecting element can also be between the at least one organic light detecting layer and the common substrate having an electrode which is formed as a non-transparent layer. An electrode formed as a non-transparent layer may in particular comprise a non-transparent metal, that is to say a metal having a sufficient thickness. All the usual metals and metal compounds that can be used for electrodes, such as those described below, are suitable for this purpose, provided that they form a nontransparent layer.

According to a further embodiment, one of the two non-transparent layers is formed by at least part of an encapsulation and / or a cover which, viewed from the common substrate, is arranged above the at least one organic light-detecting layer of the at least one light-detecting element. For this purpose, an encapsulation and / or a cover can be provided, as described below, which has at least one layer made of a non-transparent material

is formed at least in the region of the at least one organic light detecting element. Furthermore, it may also be possible that on the side facing away from the at least one organic light detecting layer

Encapsulation and / or a cover, a non-transparent cover layer is applied as described above, which forms one of the two non-transparent layers.

Furthermore, combinations of the aforementioned

Possibilities for the two non-transparent layers possible.

According to a further embodiment, the organic optoelectronic component has a plurality of organic Light detecting elements on. This means that a plurality of organic light detecting elements is arranged on the common substrate. In particular, the plurality of organic light detecting elements and the at least one organic light emitting element are arranged on the same side of the common substrate. Each of the plurality of organic light detecting

Elements preferably have at least one organic light-detecting layer, which is arranged between two non-transparent layers, which ^shade the respective at least one organic light-detecting layer from ambient light. The respective non-transparent layers may be the same or different for the individual organic light detecting elements. By means of a plurality of organic light-detecting elements, internally-conducted light can be detected, for example, at different positions of the organic optoelectronic component. As a result, it may be possible, for example, the uniformity of a

Surface light source formed organic

optoelectronic component to measure.

According to a further embodiment, a plurality of organic light-emitting elements is arranged on the common substrate. In particular, the plurality of organic light emitting elements and the at least one organic light detecting element or also a plurality of organic light detecting elements are all arranged on the same side of the common substrate. The organic light-emitting elements of the plurality of organic light-emitting elements may

For example, be controlled separately from each other, so that the individual organic light-emitting elements for example, can be switched on or off independently. Furthermore, each of at least two of the plurality of organic light-emitting elements can each detect at least one organic light

Element associated with the controller. As a result, it may be possible that the element formed by the totality of the organic light-emitting elements

Luminous surface of the organic optoelectronic component in by the organic light emitting elements

formed functional areas is divided, the

can be controlled independently of each other and controlled by means of the organic light detecting elements with respect to the respective radiated light output. That an organic light-detecting element is associated with an organic light-emitting element means, in particular, that the light-detecting element and the light-emitting element with respect to

Brightness control of the light-emitting element form a functional unit. Furthermore, it may also mean that the organic light detecting element the

associated organic light emitting element in

Comparison to other organic light-emitting

Closest to elements.

In accordance with at least one further embodiment, the organic optoelectronic component has an encapsulation on the at least one organic light-emitting element and / or on the at least one organic light

detecting element. The encapsulation can

For example, be formed by a so-called thin-film encapsulation, the at least one or more thin

Having layers which, by means of a deposition process, preferably by means of a chemical

Gasphasenabscheideverfahrens and / or a

Atomic layer deposition method, is applied to the organic light emitting element and / or on the organic light detecting element. Alternatively or additionally, the encapsulation may, for example, also have a glass cover which overlies at least one glass cover

organic light-emitting element and / or is glued over the at least one organic light detecting element on the common substrate. Furthermore, the encapsulation and a Kavitätsverkapselung, so a

Cover with a depression over the organic elements, which is applied by means of gluing, soldering, glass soldering, bonding or other suitable method.

According to a further embodiment, the at least one organic light-emitting element and the at least one organic light-detecting element are encapsulated with a common encapsulation. In other words, this means that an encapsulation on the organic light

emitting element and the organic light

is applied detecting element, which is

contiguous extending at least over both elements.

Furthermore, between the at least one organic light-emitting element and the at least one organic light-detecting element, an electrical insulator layer can be arranged directly on the substrate, which differs from the

common encapsulation is covered. The electric

Insulator layer directly on the substrate may be provided in particular to the organic light-emitting

Element electrically detecting from organic light

Electrically isolate element and / or a direct

Irradiation of light from the at least one organic light to prevent the emitting element to at least one organic light detecting element, so that in this case, light from the organic light emitting element to the light detecting element mainly or exclusively, for example by an internal light pipe through the common substrate and / or achieved by another light-conducting layer becomes.

Alternatively, it may also be possible that no electrical insulator layer is present between the at least one organic light-emitting element and the at least one organic light-detecting element. In this case, for example, a direct irradiation of light from the organic light emitting element to the organic light detecting element may be possible. In the case of a common encapsulation, in particular one

common thin-film encapsulation, this can also mean that between the at least one organic light

emissive element and the at least one organic light detecting element, the encapsulation is arranged directly on the substrate and thus between the two

Elements with the common substrate in immediate

Contact stands.

According to a further embodiment, the at least one organic light-emitting element having a first

Encapsulation and the at least one organic light

detecting element with a second one of the first

Encapsulation encapsulated separately applied encapsulation. This may in particular mean that a gap

between the at least one organic light emitting element and the at least one organic light

Detecting element is free of encapsulation. Furthermore, an electrical insulator layer can be arranged between the at least one organic light-emitting element and the at least one organic light-detecting element, which is arranged in the lateral direction between the first and second encapsulation. In other words, this may mean that the electric

Insulator layer, which preferably for electrical and / or optical isolation of the organic light emitting

Elements of organic light detecting element

is provided, is covered by any encapsulation and is thus free of encapsulating material.

According to a further embodiment is on the

Radiating side of the organic optoelectronic component arranged a decoupling layer, which is formed for example as a scattering layer and a light extraction of the light generated in the at least one organic light emitting element from the organic optoelectronic

Facilitated component. The coupling-out layer can

For example, be arranged on the organic light emitting element and the organic light detecting element side facing away from the substrate. Alternatively or additionally, a decoupling layer can also be arranged as an internal scattering layer or decoupling layer between the common substrate and the organic light-emitting element. Furthermore, it may also be possible for an outcoupling layer to additionally or alternatively be arranged on the side of the organic light-emitting element opposite the substrate.

The organic optoelectronic component described here can be compared to conventional organic

Area radiators without considerable additional effort and without considerable additional costs preferred by an unchanged

Process management in the production to be produced. By integrating the at least one organic light detecting element on the common substrate together with the at least one organic light emitting

 Element can be carried out by a suitable control in operation, a precise adjustment of the radiation power of the at least one organic light-emitting element, which may be formed in particular as a surface light element, to internal conditions such as a change in the luminance of the organic light-emitting element, which in operation, for example can lead to energy savings. In particular, a constant illumination power is at the location of the at least one organic light emitting

Elements or at the location of at least one

organic light detecting element possible. Through an automated electronic circuit called as

monolithic electronic component or as an external electronic component with a power and / or

Voltage source can be executed, which can control the at least one organic light emitting element generated by the at least one organic light detecting element generated electrically, an efficient readjustment of the illumination may be possible.

The electrodes 102, 104 are preferably formed over a large area and coherently, so that the organic light-emitting element 100 as a luminous source, in particular as a surface light source, is formed. "Large area" may mean that the organic light emitting element 100 has an area greater than or equal to a few Square millimeters, preferably greater than or equal to one

Alternatively, it may also be possible that at least one of the electrodes 102, 104 of the organic light-emitting element 100, between which the organic functional layer stack 103 is located, is structured, whereby by means of the organic light-emitting element 100 a spatially and / or temporally structured and / or changeable

In this case, the OLED 100 is designed as a so-called top emitter. The between the substrate 101 and the organic functional

is desired, also be formed reflective. Likewise, in this case, the substrate 101 may comprise a non-transparent material, such as a non-transparent glass, a non-transparent plastic, a metal, or combinations thereof. In addition to the upper electrode 104, the encapsulation 107 and, if present, also the adhesive layer 108 and the cover 109 are transparent in the top emitter configuration. Furthermore, in this case, a decoupling layer may be arranged above the upper electrode 104, for example on the cover 109 or between the cover 109 and the encapsulation 107.

In particular, the features of the basic structure of the organic light-emitting element 100 shown in FIG. 1 are not intended to be limiting for the following exemplary embodiments.

FIG. 2A shows an organic optoelectronic component according to an exemplary embodiment, which has an organic light-detecting element 200 in addition to an organic light-emitting element 100. The organic light detecting element 200 is used together with the

organic light emitting element 100 is disposed on the substrate 101 so that the substrate 101 forms a common substrate for the organic light emitting element 100 and the organic light detecting element 200. In particular, the organic light emitting element 100 and the organic light detecting element 200 are disposed on the same side of the common substrate 101 in laterally adjacent areas. The organic light emitting element 100 and the organic light detecting element 200 are thereby deposited in a same plane and in direct contact with the substrate 101 thereon.

The at least one organic light detecting layer of the organic light detecting element 200 is further arranged between two non-transparent layers 211. One of the two non-transparent layers 211, which is disposed above the organic functional layer stack 203 as viewed from the common substrate 101, is formed by the upper electrode 204 comprising a non-transparent material, for example, one above in connection with the electrodes 102 , 104 described metal such as aluminum, silver and / or magnesium. The other of the two non-transparent layers 211 is formed by a nontransparent cover layer 201, which in the exemplary embodiment shown is on the side of the common side facing away from the organic functional layer stack 203

Shield detector 200 from ambient light. The organic optoelectronic component furthermore has an encapsulation 107, which is formed as a thin-film encapsulation and forms a common encapsulation for the organic light-emitting element 100 and the organic light-detecting element 200. In other words, the encapsulation 107 extends over a large area and

coherent over the functional layers of the

organic light emitting element 100 and the

organic light detecting element 200. On the common encapsulation 107, a common cover 109 is fixed by means of an adhesive layer 108.

Furthermore, electrode connection pieces 205 are present, which serve for the electrical contacting of the electrodes 202, 204 and which may be formed like the electrode terminals 105 of the organic light emitting element 100. The electrode connection pieces 105, 205 extend from the elements 100, 200 out of the encapsulation 107, so that the elements 100, 200 can be contacted from the outside.

Between the organic light-emitting element 100 and the organic light-detecting element 200, an electrical insulator layer 112, which is covered by the common encapsulation 107, is arranged directly on the substrate 101. The electrical insulator layer 112, which may include, or may be, polyimide or other electrically insulating material, for example, serves electrical purposes

Component of Figure 2A indicates the lighting conditions during operation. In FIG. 2B as well as in the following figures, the reference signs of the individual layers and parts of the organic optoelectronic component shown in each case are, for the sake of clarity, mainly only with regard to differences from those described so far

Exemplified embodiments.

The organic light-emitting element 100 of FIGS. 2A and 2B, and thus the organic optoelectronic component shown, is pure in the exemplary embodiment shown exemplified as a bottom emitter and radiates in operation light 1 through the common substrate and the

between the organic functional layer stack and the common substrate arranged transparent electrode from. The substrate side of the organic

Optoelectronic component thus forms the

Through the transparent substrate, a part of the

organic light-emitting element 100 generated due to scattering and waveguiding effects internally in the organic optoelectronic component to the organic light detecting element 200, as indicated by the reference numeral 2. Furthermore, depending on the design of the electrodes, insulator layers and other layers and elements, it may alternatively or additionally also be possible for light in other layers to be conducted internally from the organic light-emitting element 100 to the organic light-detecting element 200,

for example, by the common encapsulation. By a targeted adaptation of the distance between the organic light emitting element 100 and the organic light detecting element 200 and in particular in the

With regard to absorption in the common substrate, by a suitable arrangement of one or more

 Decoupling layers on one or both sides of the

common substrate, by a suitable choice of material with respect to the electrodes, the insulator layers and the encapsulation, for example, with regard to a suitable refractive index for adjusting the total reflection in the substrate or the cover, as well as by suitable, at least

in places non-transparent substrate materials,

in particular, for example, in an education of the organic light-emitting element 100 as the top emitter, the proportion of internally from the organic light

emitting element 100 to the organic light

Detecting element 200 led light 2 can be set specifically.

If, as in the exemplary embodiment of FIGS. 2A and 2B, the organic light detecting element 200 has an electrode 202 between the at least one organic light-detecting layer and the common substrate 101, then in the case of a light line in the substrate 101 it is likewise transparent or has at least one

translucent area up. This may also mean that the electrode 202 is formed, for example, as a ring contact. Here and below, "annular contact" refers to any shape of an electrode which has an opening which is completely or even partially enclosed by electrode material in a lateral direction, In particular, an electrode, for example a U-shaped electrode, can also be referred to as the term

Ring contact fall.

As further shown in FIG. 2B, ambient light 3, 4 can also be applied to the organic optoelectronic component

Arrangement and design of the organic optoelectronic component on the substrate side, indicated by the

Reference numeral 3, and / or on the side of the cover, indicated by the reference numeral 4, are irradiated to the organic optoelectronic component. The

Ambient light 3, 4 may be, for example, light from other natural or artificial light sources or also light 1 of the organic optoelectronic component, which external reflection on the organic

optoelectronic component is thrown back.

Covering layer 201 on the substrate side and formed by the upper electrode 204 on the side opposite to the substrate of at least one organic light detecting layer of the organic light detecting element, a shading of ambient light 3, 4 in the region of the organic light detecting element and thus Shading of the organic light detecting layer can be achieved. In particular, the non-transparent layers 211 may be at least 90% and particularly preferably at least 99% or even greater than or equal to 99.9% impermeable to that part of the ambient light which corresponds to the absorption spectrum of the at least one

corresponds to organic light detecting layer. As a result, the influence of the ambient light 3, 4 on the electrically measurable signal of the organic light detecting

Figures 15A and 15B show the signal of the organic light detecting element of an organic

optoelectronic component in the event that the

at least one organic light detecting layer of the organic light detecting element is not disposed between two non-transparent layers, while FIGS. 16A and 16B show the corresponding signal for an organic optoelectronic device having an organic light detecting element described herein in which the at least one organic light detecting layer is disposed between two non-transparent layers. The comparison between the measured curves shows that in the case of the organic optoelectronic described here

Instead of the non-transparent cover layer 201 in

Exemplary embodiment of FIGS. 2A and 2B can be described as non- Transparent layer 211 on the substrate side, for example, a non-transparent electrode 202 or a substrate 101 may be used, which is non-transparent in the region of the organic light detecting element 200. If the organic light-emitting element 100 is designed as a top emitter, the entire common substrate 101 can also be made non-transparent. For this purpose, the substrate 101 can be formed for example by a metal foil or have a metal foil. The internal light conduction of the light 2 then takes place in this case by layers other than the substrate 101, for example the encapsulation 107 and / or the cover layer 109. Instead of a non ^¬ transparent electrode 204 as the second non-transparent layer, an additional non-transparent layer may also be used

Covering layer on the cover layer 109, be provided on the encapsulation 107 or between the electrode 204 and the encapsulation 107. Furthermore, the encapsulation 107 and / or the cover 109 may also be formed as a non-transparent layer 211 at least in the region of the organic light detecting element 200.

In the following exemplary embodiments, variations and modifications of the organic optoelectronic component according to the exemplary embodiment of FIGS. 2A and 2B are shown, which, inter alia, have variation possibilities in construction and for light detection. Can be varied

For example, the type of organic light detecting element with regard to the structure and operation and / or the electrical wiring, the number of

organic light detecting elements, the location of one or more organic light detecting elements with respect to the luminous surface of the organic light

emitting element, the detection surface of the organic Light-detecting element, for example, with respect to an adaptation to the organic light-emitting element in geometry, stack and / or wiring, the distance between the organic light detecting element and the organic light-emitting element, the arrangement and number of one or more Auskoppelschichten and / or the waveguide properties in the substrate or the rest

Encapsulation 107 is applied separately, so that the organic light emitting element 100 and organic light detecting element 200 are independently encapsulated. Between the organic light emitting element 100 and the organic light detecting element 200, as shown in FIG

Insulator layer 112 may be provided by none of

Encapsulations 107, 208 is covered.

The encapsulations 107, 208 may be the same or

be formed differently and in particular in the choice of materials, the optical properties and the

Encapsulation properties adapted to the respective requirements of the organic light emitting element 100 and the organic light detecting element 200. On the encapsulation 107, 208 is in each case a cover 109, 210 applied by means of a respective adhesive layer 108, 209, which may be performed, for example, as the common cover 109 according to the previous embodiments. However, it may also be possible that

For example, the encapsulation 208 and / or the cover 210 of the organic light detecting element 200 are formed as a non-transparent layer, while the encapsulation 107 and the cover 109 transparent depending on the desired properties of the organic light emitting element 100 regardless of the organic light detecting element 200 or non-transparent may be formed.

FIG. 4B shows an exemplary embodiment of an organic optoelectronic component which, unlike the previous exemplary embodiment, has no electrical

Insulator layer 112 between the organic light

emitting element 100 and the organic light Detecting element 200 but a gap 113 has.

By a separate encapsulation 107, 208 according to the

Embodiments of Figures 4A and 4B for the

For example, organic light emitting element 100 and organic light detecting element 200 may be applied to organic light emitting element 100

organic light detecting element 200 by scattering and / or waveguide internally conducted, for example, directly irradiated, light can be influenced. Furthermore, in the intermediate space between the encapsulations 107, 208, an electrical contacting of the elements 100, 200 take place, as shown below in connection with the figures 13 and 14.

The organic optoelectronic components described in connection with the following exemplary embodiments can also have separate encapsulations 107, 208 for the elements 100, 200 instead of the continuous common encapsulation 107 shown there.

FIG. 5 shows a further exemplary embodiment of an organic optoelectronic component which has an organic light detecting element 200 as an organic photoconductor with an organic photoconductive material 207 instead of an organic light detecting element 200 designed as an organic photodiode in comparison to the previous embodiments is formed, which generates electrical charges upon irradiation of light. For example, photoconductive organic materials may be formed as a single layer on an electrically conductive layer, such as on an electrode or on that shown in FIG. 5, as in the exemplary embodiment shown

 Electrode. For example, the organic photoconductive material 207 may be based on a PVK-TNF charge transfer complex (PVK: polyvinylcarbazole, TNF: 2, 4, 7-trinitro-9-fluorenone). Furthermore, the organic photoconductive material 207 may, for example, also be two-layered in the form of an organic charge carrier-generating layer and an organic

Charge carrier transporting layer may be formed. Suitable organic charge carrier materials are, for example, (di) azo dyes, squaraine derivatives and phthalocyanines in question, as organic charge carriers

conductive materials, for example arylamines, oxadiazoles, TPD (N, N'-bis (3-methylphenyl) -N, N'-bis (phenyl) -benzidine) and NPB (Ν, Ν'-bis (naphthalen-1-yl) - Ν, Ν'bis (phenyl) benzidine). In addition, as an organic photoconductor

formed organic light detecting element 200 has the same structure as the organic light-emitting

Thus, to prevent the irradiation of ambient light onto the organic photoconductive material 207, alternatively or additionally, non-transparent insulator layers, electrically insulated metal layers, non-transparent encapsulation materials and / or a non-transparent cover, for example a non-transparent glass cover, may be provided be.

Depending on the materials and structure of the organic light

Detecting element 200, this can also be constructed simultaneously as a photoconductor and photodiode. Such

Organic light detecting element 200 may be used with a bias voltage as a photodiode and without electrical bias as a photoconductor.

Furthermore, depending on the materials and structure, the electrical resistance of the organic light detecting element 200 may be measured, so that the organic light detecting element 200 may be formed and usable as an organic photoresistor. For example, the organic light detecting element 200 may have an organic functional layer based on pentacene for this purpose.

FIG. 6 shows a further exemplary embodiment in which, compared with the previous exemplary embodiments, the distance 114 between the organic light-emitting

Element 100 and the organic light detecting element 200 is reduced. By varying the distance 114, for example by the distance reduction or also an increase in distance, depending on the application, the proportion of the light internally guided by the organic light emitting element 100 to the organic light detecting element 200 can be influenced.

FIGS. 7A and 7B show further exemplary embodiments in which the decoupling layer 110 is varied in comparison to the exemplary embodiments shown so far. In the exemplary embodiment according to FIG. 7A, the decoupling layer 110 extends in comparison to the previous ones

 Decoupling layer 110 disposed on the organic functional layer stacking side facing the common substrate 101, which may also result in an influence on the internally conducted light.

As an alternative to the exemplary embodiments shown, no decoupling layer can also be present. If the organic optoelectronic component and in particular the organic light emitting element 100 instead of a bottom emitter formed as a top emitter or transparent OLED, one or more coupling layers in the

variants also on the side facing away from the substrate, so for example on the encapsulation, arranged be. In particular, one or more

 Decoupling layers externally, ie on an outer side, or internally, so be arranged between other layers of the organic optoelectronic device.

FIGS. 8A and 8B show further exemplary embodiments of organic optoelectronic components in which, in comparison with those shown so far
