Description

The invention relates to a light-emitting assembly and a method for operating a light-emitting assembly.

Organic-based optoelectronic components, so-called organic optoelectronic components, are increasingly being used. For example, organic light-emitting components, in particular organic light-emitting diodes (OLED), are increasingly being used in general lighting, for example as surface light sources, and are increasingly being used as display elements or signal elements.

Furthermore, it is known to use an OLED as a touch-sensitive sensor. In particular, the electrodes of an OLED form a capacitor whose capacitance changes when the OLED is touched. This change in capacitance can be detected and used to electronically detect the touch.

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 comprise one or more emitter layers in which electromagnetic radiation is generated, a charge carrier pair generation layer structure each consisting of two or more charge generating layers (CGL) for charge carrier pair generation, and one or more Electron block layers, also referred to as hole transport layers (HTL), and one or more hole block layers, also referred to as electron transport layers (ETLs), for directing the flow of current.

If the OLED has several emitter layers, for example two or three, then these can be stacked vertically one above the other. This can be used to produce light of different colors and / or color temperatures and / or white light by means of an OLED. In this case, the emitter layers can be individually controlled such that only one of the emitter layers emits light of corresponding color, or two or more of the emitter layers can be driven so that they simultaneously emit light of corresponding color, which then becomes a mixed light of a different color and / or color temperature mixes.

Furthermore, segmented OLEDs are known in which one of the two electrodes, which are segmented one or more emitter layers and / or both electrodes, whereby a plurality of light-emitting segments are formed. The individual lighting segments can be controlled jointly or independently of one another in such a way that they emit light. This makes it possible to represent various information by means of the corresponding OLEDs depending on the driven light segments. Alternatively or additionally, this can contribute to be able to continue to use a corresponding OLED, even if it has an error, if the error only one, two or a few lighting segments are affected and the other lighting segments can still be used as intended.

Furthermore, input devices are known, by means of which information, instructions, data and / or code can be entered into an electronic device. When using buttons and / or touch panels, especially their touch, it is often unclear whether the corresponding touch was detected or not. Occasionally there are animated buttons on software touchscreens that flash or move as they are touched. However, this only works with display devices of displays that are connected to relatively powerful computers. In simple devices, such as doorbells, input buttons of vending machines, pin code input fields, etc., such feedback is basically absent.

It is an object of the invention to provide a light-emitting assembly which allows in a simple, intuitive and / or cost-effective manner to input information, instructions, data and / or code into an electronic device.

An object of the invention is to provide a method of operating a light-emitting assembly that allows a simple, intuitive and / or cost-effective manner to input information, data and / or code into an electronic device.

An object of the invention is achieved by a light-emitting assembly having: at least one organic light-emitting component, which has a plurality of laterally juxtaposed light segments which are independently controllable, each of the light segments having two vertically stacked organic functional layer structures each having at least one Have emitter layer and are independently controllable; and an electronic circuit configured to detect dynamic contact of at least two of the light segments in response to the detected dynamic touch To control lighting segments such that at least one of the two corresponding emitter layers emits light to determine by means of a predetermined assignment rule based on the dynamic touch of the corresponding light segments at least one parameter value associated with the dynamic touch, and to generate a signal which is representative of the parameter value ,

The dynamic touch is representative of information, instruction, data and / or code. The fact that the touch is dynamic means that one, two or more small areas of an optically active outer surface of the organic light-emitting device are touched simultaneously, for example by means of a finger or a stylus, and then, while maintaining the touch, the position of the touch on the optically active Outside surface is changed. The dynamic contact is therefore in contrast to a static contact, in which only a small area on the optically active outer surface of the organic light emitting device would be statically touched. In the case of dynamic contact, one, two or more of the luminous segments are thus touched simultaneously and then one, two or more other of the luminous segments are then touched in time directly thereafter. Entering information, instructions, data or code using a dynamic touch is particularly easy and particularly intuitive.

The dynamic touches correspond to sequences of touched light segments. In other words, a particular sequence of touched light segments is representative of a particular dynamic touch. In the assignment rule different dynamic touches or the corresponding sequences of touched light segments are stored. In addition, different parameter values are assigned to the dynamic touches or the corresponding sequences of touched light segments in the assignment rule. The parameter values thus correspond to the information, instruction, data or the code.

The organic light-emitting component with the light segments may be formed as a segmented OLED.

The individual lighting segments serve as touch sensors, in particular capacitive touch sensors. All light segments together form a field of touch sensors. In particular, a two-dimensional array of touch sensors can be provided by means of the luminous segments.

At the same time, the individual lighting segments serve as light signal transmitters, which give a person, who touches the organic light-emitting component dynamically, direct feedback, in particular a direct feedback, to which the lighting segments were touched. This helps to make entering the information, instruction, data or code particularly easy and intuitive.

The light emitting assembly serves as an input device for inputting information, data, instructions and / or code into an electronic device. For this purpose, the light-emitting assembly may be coupled to the electronic device. The use of the organic light-emitting device with the light-emitting segments and the electronic circuit as an input unit can help to provide a particularly cost-effective input device and / or provide an input device that places only small demands on the electronic device. For example, the input device can be used with the light-emitting assembly in relatively simple electronic devices, such as doorbells, vending machines or ATMs. In this case, "relatively simple" means that the electronic device does not have to be a desktop computer, laptop computer, tablet computer or smartphone.

The coupling between the light-emitting assembly and the electronic device may be, for example, a wired or a wireless coupling. Furthermore, the light-emitting assembly and the electronic device may be arranged in a common housing. The signal representative of the parameter value is thus representative of the information, instruction, data, or code that is to be input to the electronic device by means of the light-emitting assembly.

Thus, the light-emitting assembly enables a simple, intuitive and / or cost-effective way to input information, instructions, data and / or code in an electronic device.

According to a development, the dynamic touch is a gesture or a swipe movement. The gestures or wiping movements can be chosen such that the input of the information, instruction, data or codes are particularly intuitive.

According to a development, the touched lighting segments are controlled in such a way in response to the wiping movement that a track, along which the wiping movement has taken place, by means of touched light segments is displayed. In other words, touched lighting segments, even after the contact is over, are still driven for a predetermined period of time in such a way that they shine, in particular at least one of the corresponding emitter layers.

According to a development, the lighting segments are controlled along the track such that their brightness and / or color change as time progresses. For example, already touched lighting segments, after the contact is over, be further controlled for the predetermined period of time, that these, in particular at least one of the corresponding emitter layers, emit light, with increasing intensity and / or brightness of the corresponding light decreases with increasing time and / or a color of the corresponding light changes. This can help to make the feedback to the person who has performed the dynamic movement particularly intuitive and / or memorable.

According to a further development, the corresponding light segments are controlled in such a way in response to the detected dynamic contact that both corresponding emitter layers emit light. Thus, for example, depending on the nature of the detected touch or the information, instruction, data or code for which the dynamic touch is representative, only one of the emitter layers, both emitter layers or optionally more than two of the emitter layers may be driven sequentially or simultaneously whereby, in relation to the detected touch, the feedback may be provided by means of light of different colors and / or changing colors. This allows not only to provide feedback on which dynamic touch was detected, in particular which of the light segments were touched, but also to give feedback on what information, instruction, data or code was detected. In particular, in that depending on the recognized information, instruction, data or code, various optical feedbacks are given.

According to a development, each of the luminous segments has at least three organic functional layer structures stacked on top of one another, each with at least one emitter layer. This makes it possible to emit light of three colors, and / or to emit light of more than three colors, in particular mixed colors, by mixing the light of the three or more emitter layers.

According to a further development, the emitter layers are designed such that one of the emitter layers emits red light during operation, with corresponding activation, one of the emitter layers emits green light and one of the emitter layers emits blue light. This makes it possible to emit white light by means of the emitter layers and / or to emit light of different color temperatures.

An object of the invention is achieved by a method for operating the light emitting assembly, wherein: the dynamic contact of at least two of the light emitting segments of the organic light emitting device is detected, wherein the light emitting assembly comprises an electronic circuit and a plurality of laterally adjacent to each other connected to the electronic circuit Luminous segments which are independently controllable, and wherein each of the light-emitting segments has two vertically stacked emitter layers, which are independently controllable; the touched light segments are driven in response to the detected dynamic touch such that at least one of the two corresponding emitter layers emits light; on the basis of the dynamic contact of the corresponding lighting segments, at least the parameter value associated with the dynamic touch is determined by means of the predetermined assignment rule; and the signal representative of the determined parameter value is generated.

The developments and / or advantages explained above in connection with the light-emitting module can be readily transferred to the method for operating the light-emitting module.

According to a development, the dynamic touch is the gesture or the swipe movement.

According to a development, the touched lighting segments are controlled in such a way in response to the wiping movement that the track along which the wiping movement has taken place is indicated by means of the touched lighting segments.

According to a development, the lighting segments are controlled along the track such that their brightness and / or color change as time progresses.

According to a further development, the corresponding light segments are controlled in such a way in response to the detected dynamic contact that both corresponding emitter layers emit light. This makes it possible to mix the light of the two emitter layers. This makes it possible, by means of the two emitter layers, to produce mixed light with at least one further color in addition to the light of the color of the individual emitter layers.

According to a further development, in response to the detected dynamic contact, the corresponding lighting segments are controlled in such a way that the corresponding emitter layers permanently emit light for a predetermined period of time. This allows to provide the feedback by means of permanent light emission.

According to a further development, in response to the detected dynamic touch, the corresponding lighting segments are controlled in such a way that the corresponding emitter layers flash. This allows to provide the feedback by means of interrupted light emission.

According to a further development, the emitter layers are designed such that one of the emitter layers emits red light during operation, with corresponding activation, one of the emitter layers emits green light and one of the emitter layers emits blue light.

2 shows a plan view of an optically active region of an embodiment of an organic light-emitting device 10 , for example, the organic light-emitting device 10 according to 1 in a first condition. The organic light emitting device 10 has in rows and columns laterally juxtaposed light segments 40 on.

By means of a dynamic touch, one or more of the light segments can 40 be touched. The dynamic touch may be, for example, a swipe or a gesture. During the wiping movement, for example by means of a finger or a pin, several of the lighting segments 40 are touched successively by wiping over the optically active area by means of the finger or the stylus. A wiping direction 44 represents a wiping motion in which of the luminous segments 40 first a first light segment 50 touched and thereby activated, then a second light segment 52 touched and thereby activated, then a third light segment 54 is touched and thereby activated and then a fourth light segment 56 touched and thereby activated.

The dynamic touch, in particular the sequence of contacts leading to the activation of the activated light segments 50 . 52 . 54 . 56 Initially, lead to changes in capacitance by the electrodes 20 . 23 . 27 the corresponding lighting segments 40 are formed. These changes in capacity can be made by means of the electronic circuit 8th be recorded. The electronic circuit 8th activates the corresponding light segments 40 so that the activated lighting segments 50 . 52 . 54 . 56 to shine. When activating the light segments 40 may be the corresponding lateral portions of the first organic functional layer structure 22 and / or the second organic functional layer structure 25 the corresponding lighting segments 40 to be activated.

The dynamic touches are used to pass through the light-emitting assembly 1 To enter information, data and / or code into an external device. In addition to activating the activated light segments 50 . 52 . 54 . 56 determines the electronic circuit 8th based on a stored assignment rule one, two or more parameters that the touched and subsequently activated lighting segments 50 . 52 . 54 . 56 and thus associated with the corresponding dynamic touch. The parameter (s) are representative of the dynamic touch and may be passed to the electronic device in the form of a signal. The electronic device can use or decrypt the information, the data and / or the code on the basis of the parameters.

The activated light segments 50 . 52 . 54 . 56 form a track of the wiping motion, which is the wiping direction 44 represents. The electronic circuit 8th can activate the activated light segments 50 . 52 . 54 . 56 such that the track for a predetermined period of time after touching the activated light segments 50 . 52 . 54 . 56 is shown. The electronic circuit 8th can activate the activated light segments 50 . 52 . 54 . 56 For example, in such a way that, as the time progresses, the brightness of the activated luminous segments increases 50 . 52 . 54 . 56 emitted light decreases so that the displayed track fades with increasing duration. Alternatively or additionally, the electronic circuit 8th the activated light segments 50 . 52 . 54 . 56 to control such that the color progresses with time and / or the color temperature of the activated luminous segments 50 . 52 . 54 . 56 radiated light changes.

For example, the activated light segments 50 . 52 . 54 . 56 be controlled so that immediately after their contact all emitter layers of the corresponding activated light segments 50 . 52 . 54 . 56 Emit light and that as the time progresses, a decreasing number of emitter layers of the respective activated light segments 50 . 52 . 54 . 56 Emit light. Alternatively, the activated lighting segments 50 . 52 . 54 . 56 be controlled so that directly after touching the corresponding activated light segments 50 . 52 . 54 . 56 first each one of the emitter layers of the corresponding activated light segments 50 . 52 . 54 . 56 Light emits and subsequently each an increasing number of emitter layers of the corresponding activated light segments 50 . 52 . 54 . 56 Emit light. Both approaches make it possible to change the color of the displayed track as the time progresses, provided that the vertically stacked emitter layers emit light of different color.

Furthermore, the activated lighting segments 50 . 52 . 54 . 56 be controlled such that, although several emitter layers of each activated luminous segment 50 . 52 . 54 . 56 light up, however, that as the time progresses, the brightness of the light of each of the emitter layers is changed. For example, a change in the color temperature can be made in this way. For example, each of the light segments 40 vertically above each other have three emitter layers, in particular a red light emitting emitter layer, a blue light emitting emitter layer and a green light emitting emitter layer. Immediately after the touch you can activate the activated light segments 50 . 52 . 54 . 56 be driven so that they emit, for example, first cold white light, for example by the blue light emitting emitter layer is driven so that it emits a lot of blue light, and by the red light emitting emitter layer is driven so that it emits little red light. As the time progresses, the same activated luminous segments can then be activated 50 . 52 . 54 . 56 be driven so that the corresponding blue light emitting emitter layers gradually emit less blue light and emit the red light emitting emitter layers gradually more and more red light. The optical effect achieved is that the track is first displayed cold-white and then displayed, for example, with a smooth transition, warm white.

In addition, mixtures of the above-described modes of operation are possible, for example, both individual emitter layers can be switched on or off as the time progresses, and / or individual emitter layers can be driven in such a way that they emit light with increasing or decreasing brightness.

The activated light segments 50 . 52 . 54 . 56 and in particular, enabling the track to be displayed to a user of the light-emitting assembly 1 to give direct visual feedback that its dynamic touch has been detected. The multiple possibilities explained above, the activated light segments 50 . 52 . 54 . 56 After having touched them open up a wide range of possibilities to give the user various optical feedbacks. As a result, the user can not only be given feedback about which of the light segments 40 but also what the corresponding dynamic touch means or causes.

For example, the activated light segments 50 . 52 . 54 . 56 be so long driven so that they emit red light, for example, and / or that they flash, for example, until the corresponding dynamic touch a predetermined parameter could be assigned and / or a predetermined information, predetermined instruction, predetermined data and / or a predetermined code recognized were. After the predefined parameter could be assigned to the corresponding dynamic touch or the specified information, the specified instruction, the given data or the predetermined code were recognized, the activated light segments can 50 . 52 . 54 . 56 be controlled so that they emit green light and / or permanently lit, for example.

For example, if the dynamic touch is used to activate an opening mechanism, for example, the track may be displayed in red and / or flashing until the dynamic touch is detected as being sufficient for opening the opening mechanism, and then the track may turn green and off / or permanently lit.
