ORGANIC LIGHT-EMITTING COMPONENT, METHOD FOR MANUFACTURING AN ORGANIC LIGHT-EMITTING COMPONENT, AND METHOD FOR OPERATING AN ORGANIC LIGHT-EMITTING COMPONENT

DESCRIPTION

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

Operating an organic light emitting device.

Organic-based light-emitting components,

so-called organic light-emitting components, find increasingly widespread application. For example, organic light-emitting diodes (organic light-emitting diode (OLED) are increasingly being used in general lighting, for example as area light sources. An organic light-emitting device, such as an OLED, may include an anode and a cathode and an organic functional layer system therebetween. The organic functional layer system may include one or more emitter layers in which electromagnetic radiation is generated, a charge carrier pair generation layer structure of two or more each

Charge pair generation charge generating layer (CGL) and one or more electron block layers, also referred to as hole transport layer (HTL), and one or more hole block layers, also referred to as electron transport layers ("electron Until now, regardless of this, for a position determination in a building, for example for a GPS-free

Navigation in closed spaces, for example in a department store, in a parking garage, in a subway station, in a museum, in an industrial building and / or a

Warehouse permanently installed radio transmitter needed. These

Radio transmitters regularly send out an identification number (ID) in the form of a radio signal, usually in the GHz range. This signal may be from handheld devices, for example

Smartphones, tablets, smartwatches and / or robots or drones for positioning purposes.

Such radio transmitters are now also referred to as beacons. Beacons are usually battery-powered radio transmitters, for example, a Bluetooth signal

send out. It is known to arrange in addition to lamps beacons in lights that are used to illuminate the corresponding building, in particular room. In this case, the corresponding beacon can use the power supply of the corresponding lamp and does not require a battery. The word beacon derives from the English term for, beacon * and is an indication of that

Operating principle. Beacons are based on a transmitter-receiver principle. For this purpose, several beacons are placed in the room as signal transmitters, which send signals at fixed time intervals. If a recipient, for example a smartphone with an installed mobile app that is configured to receive iBeacon signals, is within the range of a beacon, the sender's ID can be identified and his

Signal strength are measured. If at least three beacons are within range of the end device, the position of the receiver in two-dimensional space can be calculated, for example by trilateration or the fingerprinting method. to

Identifying a location in a three-dimensional space requires four beacons within range.

Already during the spatial planning, lights are being replaced

Architectural buttons are arranged and so are defined

Positions equipped with appropriate beacons. In conventional luminaires, the radio elements of the beacons are hidden inside the housing of the corresponding luminaire. To avoid a shielding of the radio signal are for Plastic housing used or, in the case of a metal housing, the antennas of the beacons from the

Led out metal housing. The formation of the beacons, the placement of the beacons in the housings of the luminaires and / or the bringing out of the antennas of the beacons from the housings is usually very

costly and / or time consuming. An object of the invention is to provide an organic

To provide light emitting device having a radio transmitter and / or a radio receiver and which is simple, fast and / or inexpensive to produce. An object of the invention is to provide a method for

Producing an organic light-emitting component which has a radio transmitter and / or a radio receiver to provide, which is simple, fast and / or inexpensive to carry out.

An object of the invention is to provide a method for

Operating an organic light emitting device having a radio transmitter and / or a radio receiver to provide, in a simple and / or cost-effective manner, a reliable transmission or reception of

Information allows.

An object of the invention is achieved by an organic light emitting device comprising: a

Metal layer structure comprising a first electrode and an antenna; an organic functional

Layer structure over the first electrode; a second electrode over the organic functional

Layer structure; and an electronic circuit, which is at least electrically coupled to the antenna and which is adapted, in the operation of the organic

Light-emitting device to apply a first electrical signal to the antenna, so that the antenna to a corresponding first electromagnetic signal

emits, and / or from the antenna to receive a second electrical signal which is generated due to a second electromagnetic signal received by the antenna.

The antenna consists of one or more active or passive antenna elements, for example parasitic

Antenna elements. The length of the antenna, in particular of the antenna elements, and / or distances of the antenna elements from one another depend on the desired transmission and / or reception frequency range. For example, for transmitting and / or receiving in the 2.4 GHz range, for example in the Bluetooth range, a length of the antenna and / or the

Antenna elements be about 5 cm. The metal layer structure, in particular the antenna, in particular the antenna elements, consists of a conductive material, for example ITO, PEDOT.PSS, CrAlCr, Ag, Cu, Au. The metal layer structure is a laterally structured surface, wherein the antenna and the first electrode are formed by the lateral structures. For the supply or also decoupling of the signal, for example an RF signal, the antenna,

in particular the antenna elements, with one or more connection elements of the electronic circuit

connected. The antenna can be designed, for example, in the form of a vaginal antenna or in the form of a logarithmic periodic antenna.

The organic light-emitting component, also referred to below as OLED for short, is a lamp and / or a lamp

Illuminant that in a lamp, such as a

Ceiling light, a wall light and / or a floor lamp, can be arranged.

The integration of the antenna in the layer structure of the OLED and thus the integration of the antenna directly into the lamp or the illuminant cause on the one hand, that the antenna always on the front and / or on an outwardly open side of a housing of the lamp, in the the OLED arranged is, is arranged, since lamps or bulbs in principle at an outwardly open position of the

Housing of the lights are arranged so that the light emitted by the corresponding lamp or the corresponding

Light source is generated, can be radiated to the outside. This positioning of the antenna is particularly favorable, since only a particularly small, negligible or no electromagnetic shielding of the signal takes place through the housing of the lamp. This allows one

To use metal housing for the corresponding lamp, without having to lead the antenna out of the metal housing. In addition, this contributes to the fact that the transmission and / or reception power is in principle very good. This helps to ensure that information with a particularly low energy consumption is reliable via the antenna

can be broadcast or received with a

particularly high accuracy can be radiated or received. The integration of the antenna in the layer structure of the OLED and thus the integration of the antenna directly into the lamp or the lighting means, on the other hand, cause the

Manufacturing costs and the manufacturing costs can be kept particularly low, since the antenna and the corresponding lateral structures of the metal layer structure can be produced in the same process steps as others

Structures of the OLED, for example, the first electrode, contact portions of the OLED or power distribution elements, such as busbars, the OLED.

In addition to the antenna, one, two or more further antennas can be integrated into the layer structure of the OLED. Alternatively or additionally, in each case one, two or more antenna elements can be inserted into the antenna or the antennas

exhibit. The antenna or the antenna elements can be interconnected so that this leads to an improvement of the emission direction and the reception improvement.

Alternatively, this can reduce the transmission power, whereby energy can be saved and / or electrosmog can be reduced. Furthermore, a failure of a

Antenna or an antenna element by the redundancy due to the other antennas or antenna elements

be compensated.

According to a development, the antenna is formed laterally next to the first electrode. The first electrode, the organic functional layer structure and the second electrode define one in the region in which they overlap in the lateral direction during operation of the OLED

Illuminated area of the OLED. Arranging the antenna laterally adjacent to the first electrode causes the antenna to be located outside the luminous area. In other words, the conductive structure of the antenna is not in the luminous one

Area of the OLED, which is formed for example as a surface light source arranged. This allows a material to be selected for the antenna that does not

transparent or not translucent. Optionally, however, a transparent or translucent material for the antenna can be selected.

According to a development, the antenna is electrically insulated from the first electrode. This causes the first signal, which is radiated by means of the antenna, or the second signal, which is received by means of the antenna, not to be influenced by a current or a voltage which flows in the lighting operation of the OLED via the first electrode is in lighting operation of the OLED at the first electrode.

According to a development, the antenna is formed vertically above or below the first electrode. clear

Spoken the antenna is arranged within the luminous area of the OLED. This can help one

Shielding of the antenna due to other materials of the OLED or due to a housing of a luminaire, in which the OLED is arranged, is particularly low, since the luminous surface a light source in a lamp is not or only shielded as little as possible. Furthermore, this can offer a relatively large margin in the choice of the size and / or the shape of the antenna, since the luminous surfaces of OLEDs are basically relatively large and therefore there is sufficient space in the region of the luminous area for different sizes and / or shapes of the antenna. Further, this makes it possible to use the antenna for distributing a current used for generating the lighting operation of the OLED.

According to a development, the antenna is in direct

physical contact with the first electrode. In other words, the conductive lateral structures of the antenna are in direct physical contact with the first one

Electrode within the illuminated area. This causes a current flowing across the first electrode to also flow across the antenna, thus contributing to the conduction and / or distribution of the current across the light area. According to a development, the antenna is formed vertically above or below the second electrode. clear

Shielding of the antenna due to other materials of the OLED or due to a housing of a luminaire in which the OLED is arranged, is particularly low, since the luminous surface of a luminous means in a luminaire is not shielded or shielded as little as possible. Furthermore, this can offer a relatively large margin in the choice of the size and / or the shape of the antenna, since the luminous surfaces of OLEDs are basically relatively large and therefore there is sufficient space in the region of the luminous area for different sizes and / or shapes of the antenna. Further, this makes it possible to use the antenna for distributing a current used for generating the lighting operation of the OLED.

According to a development, the antenna is in direct physical contact with the second electrode. In other In other words, the conductive lateral structures of the antenna are in direct physical contact with the second electrode within the light-emitting surface. This causes a current that flows through the second electrode to also flow via the antenna, and thus the antenna contributes to conducting and / or distributing the current across the luminous area.

According to a development, the antenna serves as

Current distribution structure for uniformly distributing current through the first electrode and the second electrode. The lateral structures of the antenna thus serve both for transmitting and / or receiving information, in particular data, as well as for power distribution, for example

Current spreading. The antenna may also be referred to as power distribution element or busbar in this context and / or be formed. A separation of the for the

Light function used current, such as a

Direct current, and the first and second signal, which may be in the RF range, for example, is performed by the electronic circuit. The system of lighting means and transmitting and receiving means is then operated with a modulated electrical signal.

According to a development, the antenna is embedded in the organic functional layer structure. In other words, the antenna is surrounded in two or three spatial directions by the material of the organic functional layer structure. Optionally, between the antenna and the material of the organic functional layer structure

electrically insulating material, for example a

electrically insulating paint, be formed.

According to a development, the antenna is designed for transmitting and / or receiving frequencies in the GHz range.

For example, the antenna and / or antenna elements of the antenna each have a length of about 5 cm.

Alternatively, frequencies in generation 5

Mobile network sent and / or received, For example, between € 000 Mhz and 18000 Mhz, for example, with a length of the antenna and / or the

Antenna elements from 0.4 cm to 1.5 cm. Alternatively, frequencies in the WLAN area may be received and / or transmitted, for example between 2400 MHz and 5000 MHz, for example with a length of the antenna and / or the

Antenna elements from 1.4 cm to 14 cm. Alternatively, frequencies in the radio beacon range may be received and / or transmitted, for example at approximately 2400 MHz, for example with a length of the antenna and / or antenna elements of approximately 3 cm. Alternatively, frequencies in the

Generation 4 mobile network (LTE) are received and / or sent, for example at about 2100 MHz, for example, with a length of the antenna and / or the antenna elements from 3 cm to 20 cm.

The integration of the antenna in the layer structure of the OLED and thus the integration of the antenna directly into the lamp or the lighting means, on the other hand, cause the

Manufacturing costs and manufacturing costs can be kept very low, since the antenna and the corresponding lateral structures of the metal layer structure can be made in the same process steps as others

In addition to the antenna, one, two or more further antennas can be integrated into the layer structure of the OLED. Alternatively or additionally, the antenna or the

Antennas one, two or more antenna elements

exhibit. The antenna or the antenna elements can be switched together so that this leads to an improvement of the emission direction and the reception improvement.

Alternatively, the transmission power can thereby be reduced, whereby energy can be saved and / or electrosmog can be reduced. Furthermore, a failure of a

be compensated.

An object of the invention is achieved by a method for operating the organic light emitting device, which in the layer structure of the organic

Information the first electrical signal is generated and the first electrical signal is applied to the antenna, so that the antenna corresponding thereto first

electromagnetic signal radiates; and / or by means of the antenna, the second electromagnetic signal, the

is representative of the second information and that generates in the antenna, the second electrical signal is received, and wherein by means of the electronic circuit, the second electrical signal is received by the antenna.

The advantages mentioned above and / or

Further developments of the organic light-emitting Component can be easily applied to the process for

Operation of the organic light-emitting device to be transmitted. A repeat of the corresponding

Advantages and training is therefore omitted at this point.

According to a development is to effect a
