Valuable or security document with LED elements

Description

It is known from the state of the art to provide valuable or security documents, such as banknotes, identity cards, driving licenses, stamps, admission tickets, tokens, credit cards, check cards, shares, packaging and the like, with security features that make the forgery or unauthorized modification of such documents difficult or even impossible. In

In this sense, it also refers to a product which is provided with a corresponding security feature.

Well-known security features include watermarks. Such watermarks become visible when viewed against the light and then show a specific motif or value, such as the face value of the banknote in question.

Another security feature is the security thread. The security check is carried out in such a way that a darker line must be visible in the backlight.

It is also known to apply special foil strips with security features, such as holograms. The holograms make it possible, for example, for different symbols or numbers to appear when a banknote is tilted, depending on the viewing angle.

Another way to create security features is to use pearlescent strips. When the banknote is tilted, a gold-colored strip becomes visible, in which a symbol and the respective value can be recognized. Such a pearlescent strip can be found on the 20-EURO note, for example.

The security features mentioned are so-called "public features", i.e. security features that can be checked by anyone without the use of special devices and without requiring any special knowledge.

The invention is based on the object of creating an improved valuable or security document, as well as a system for checking a security feature and a method for producing such a valuable or security document.

The problem underlying the invention is solved with the features of the independent patent claims. Preferred embodiments of the invention are specified in the dependent patent claims.

• ···· · t t

According to the invention, a security feature is implemented using one or more LED elements of the value or security document. The LED elements are preferably applied by printing. The use of organic LEDs, so-called OLEDs, is generally particularly advantageous.

A valuable or security document equipped according to the invention with one or more organic light-emitting diodes (LEDs), preferably OLEDs, has the following advantages over the prior art, among others:

OLEDs are luminous and can therefore be easily verified as a security feature even under normal ambient light conditions. OLEDs can therefore be used to impressively display so-called "public features" such as patterns, shapes, lettering, numbering, logos, etc. on a valuable or security document.

- A security feature stored by an (O)LED element is forgery-proof, since the production of functional (O)LEDs is technologically very demanding.

According to a preferred embodiment of the invention, LEDs of different colors are located on the valuable or security document. The color can be used as an additional information parameter, for example for coding.

According to a further preferred embodiment of the invention, several LEDs are applied to the valuable or security document, which are "personalizable". This means that first a predetermined pattern, such as a matrix of LEDs, is applied to the valuable or security document, for example by printing. A subset of these LEDs is then specifically activated or deactivated in order to encode information in this way.

The encoding of information into the LEDs by targeted activation or deactivation is called "personalization". Depending on the application, this can be

The information stored can be very different. For example, personal data such as name, address, date of birth and/or biometric data and/or image information is encoded in an identification document by personalizing the LEDs. For other applications, the information can be, for example, the name of a financial institution or an indication of value, such as postage in the case of stamps or the deposit value in the case of packaging. Furthermore, manufacturer-specific information can also be stored through personalization, such as a serial number or the like. Personalization can take place at different stages of the production or use of the valuable or security document. One possibility is for the personalization to be carried out directly by the manufacturer of the valuable or security document. This requires that the information to be stored is already available at the production stage of the valuable or security document. Another possibility is to first produce a "blank" of the valuable or security document, which has a non-personalized LED matrix. This blank is then personalized by the user by specifically activating or deactivating LEDs in the matrix. In the case of an identity card, this can be done by the authority that issues the identity card, for example. In the case of credit cards and the like, the personalization can be done by the financial institution.

To produce the blank of the valuable or security document, a matrix of functional LEDs is preferably produced. A subset of these LEDs is then selectively destroyed in order to store the desired information in the LED matrix. The selective destruction of the LEDs in this subset can be done thermally, for example, using a laser beam.

According to a preferred embodiment of the invention, products are coded by personalizing the LEDs. This can be done by integrating a security or value document into the packaging of the product in question and/or into the product itself. Information from the manufacturer of the product is then coded into the security or value document, such as a serial number or the like.

Such coding can also be used as a protective measure against product piracy. Another application is the coding of a deposit value, for example on a bottle label, using a correspondingly personalized OLED matrix on the label.

According to a preferred embodiment of the invention, biometric information parameters are stored on the valuable or security document by personalizing the LEDs. Such biometric information parameters can be, for example, the characteristic points for a fingerprint or iris scan or for a facial recognition routine. For storing the position of such characteristic points, it is particularly advantageous if they are mapped onto a two-dimensional LED matrix, with the LED matrix being personalized accordingly. There is then no need to convert the characteristic points, for example into a numerical code, which saves the corresponding computing effort, particularly for reading the position of the characteristic points.

According to a further preferred embodiment of the invention, an energy source for supplying voltage to the LEDs is present on the valuable or security document. This energy source is preferably a passive energy source, i.e. an energy converter that draws energy from the environment and converts it into electrical energy.

According to a preferred embodiment of the invention, one or more solar cells are used as a passive energy source.

According to a further preferred embodiment of the invention, one or more antennas on the valuable or security document are used as a passive energy source. When a signal of a suitable frequency is received, the antenna generates sufficient energy to supply the LEDs with voltage. It is possible to provide antennas for different frequencies in order to achieve a coding effect in this way. For example,

Different antennas are connected to LEDs of different colors, so that the color impression changes when moving through the frequency range.

According to a further preferred embodiment of the invention, the passive energy sources and OLEDs are arranged on the same carrier. The carrier can be, for example, a layer of polyethylene, polyester, glass or paper. It is particularly advantageous that both OLEDs and solar cells can be produced as thin layers, with layer thicknesses in the micrometer range. This ensures optimal integration into the valuable or security document. The production of such OLEDs is known per se from "OLED Matrix Displays: Technology and Fundamentals", Polytronic 2001, Conference Procedings, October 21-24, 2001; the production of solar cells as thin layers is known per se from "Plastic Solar Cells", Adv. Funct. Mater. 2001, 11, No. 1, February, pages 15 to 26.

What is particularly advantageous is that LEDs, preferably OLEDs and solar cells, can also be produced using printing technology, for example using inkjet printing, screen printing, letterpress printing, gravure printing, planographic printing or other printing processes. The printing technology used to produce conductor tracks is already known.

In all embodiments of the electrodes, one electrode must always be semi- or fully transparent. To ensure this, an electrode is preferably made of ITO material.

According to a further preferred embodiment of the invention, one or more metal threads are used in the valuable or security document to create antennas. The introduction of metal threads into banknotes is known per se; the metal threads are introduced into the paper used to produce the banknotes during paper production. Such a production method can also be used to introduce metal threads into a valuable or security document according to the invention in order to create one or more antennas.

The invention further provides a system for checking a security feature on a document that is implemented by an LED matrix. Such a system has an energy source to supply energy to the passive energy source of the valuable or security document. A transmitter can be used as an energy source for the system, for example, to couple an electromagnetic field into the antennas of the document in order to light up the LEDs. Alternatively or additionally, a light source is provided to supply energy to the solar cell on the valuable or security document.

Such a system can be used, for example, to verify biometric characteristics. To do this, the system first records the biometric characteristics of the person in question and then compares them with the characteristics encoded in the LEDs.

The embodiments of the invention can be realized both with LEDs and with OLEDs, whereby the realization with the aid of OLEDs is preferred, in particular because of the better possibility of printing the OLEDs.

Preferred embodiments of the invention are explained in more detail below with reference to the drawings.

Figure 9 is a block diagram of an embodiment of a system for checking

function of a security feature.

Figure 1 shows a document 1. The document 1 is a valuable or security document, such as a banknote, an identity card, passport, driving license or the like. On or in the document 1 there is at least one LED element 2. The LED element 2 is preferably made using thin-film technology, with a layer thickness in the micrometer range. In this case, optimal integration into the document 1 is ensured.

Glass is the preferred substrate for the realization of LED element 2. Glass has the best barrier properties against oxygen and water, but only allows for limited bending radii. Indium titanium oxide (ITO) glass, for example, is suitable as a glass substrate material. If small bending radii are to be achieved, the use of flexible substrates is preferred, such as substrates made of plastic, paper or ITO film.

Furthermore, there is an energy source 3 on the document 1. The energy source 3 is an active or a passive energy source. For example,

the energy source 3 can be realized as an active energy source in the form of a printed battery.

In contrast to a battery, a passive energy source extracts energy from the environment in order to convert it into another form of energy. To implement such a passive energy source, the energy source 3 can be designed as a solar cell or as an antenna.

The energy source 3 serves to supply current and/or voltage to the LED element 2 via the lines 4 and 5. Preferably, the LED element 2, the energy source 3 and the lines 4 and 5 are implemented on the same carrier. This has the advantage that the arrangement consisting of the LED element 2, energy source 3 and lines 4 and 5 can be integrated into the document 1 in the form of a uniform layer.

A particular advantage of OLEDs is that they are generally very luminous and can therefore be recognized under normal ambient light conditions. A security feature provided by the OLED element 2 can therefore be easily verified without the document 1 having to be held against the light or under a special lighting source.

The LED element 2 can be a single light-emitting diode that lights up as soon as a voltage is supplied from the energy source 3. However, it can also be several light-emitting diodes that are arranged in a certain pattern, for example. By arranging the LEDs accordingly, numerical or alphanumeric codes can be displayed, as well as lettering, numbering, logos and other symbols.

Since the production of LED elements is technologically very demanding, the security feature implemented by the LED element 2 is practically impossible to counterfeit. If the LED element 2 lights up after the energy source 3 is activated, this verifies the authenticity of the document 1.

, In addition to checking the authenticity of document 1, other applications are also possible, such as for authentication purposes. This is explained in more detail below, particularly with reference to Figure 9.

Figure 2 shows a further embodiment of document 1. Elements of Figure 2 which correspond to elements of Figure 1 are identified by the same reference numerals.

In the embodiment of Figure 2, the energy source 3 is designed as a solar cell 6. The production of solar cells using thin-film technology is known per se from the prior art.

The LED element 2 of Figure 1 is designed as an LED matrix 7 in the embodiment of Figure 2. Several LEDs are arranged in a matrix in the LED matrix 7. The production of such an LED matrix 7 is also known from the prior art, in particular in thin-film technology. Preferably, the solar cell 6 and the LED matrix 7 are again produced on the same carrier and also galvanically connected via this common carrier via the lines 4 and 5. These lines and an electrode of both the source and the feature can in particular consist of one and the same material, the same layer, preferably ITO, i.e. can be applied in one production step.

The connection of the LED matrix 7 to the energy source - in this case to the solar cell 6 - is carried out in such a way that each LED of the LED matrix 7 is supplied with a sufficiently high voltage. Preferably, the LEDs of the LED matrix are connected in parallel or controlled individually.

After the thin-film element consisting of the solar cell 6, the LED matrix 7 and the lines 4 and 5 has been manufactured, the LED matrix 7 is personalized. Personalizing here means that a specific subset of LEDs in the LED matrix 7 is destroyed in a targeted manner. The targeted destruction of specific LEDs can

it» ·»*· *i> *rt ·· ·♦♦♦

thermally. For this purpose, a laser beam can be used, which is briefly directed at the LEDs of the LED matrix 7 that are to be destroyed.

This personalization creates a pattern of functional LEDs in the LED matrix 7. When the solar cell 6 supplies energy, the corresponding LEDs of the LED matrix 7 light up so that the pattern can be viewed or recorded by a user or a sensor to check the security feature. In a further embodiment, the illuminated pattern shown by the LED matrix 7 can be machine-readable, for example by showing a barcode or coded or uncoded biometric features.

The coding of characteristic points for fingerprint, iris or face recognition can be carried out particularly advantageously by mapping the relevant characteristic points onto the two-dimensional LED matrix 7 according to their position and personalizing the LED matrix 7 accordingly. This eliminates the otherwise required conversion of the spatial position of such characteristic points into coded numerical values. In particular, this also saves the otherwise required processing effort for decoding, since the spatial position of the characteristic points can be deduced directly from the arrangement of the illuminated points of the LED matrix 7.

Figure 3 shows a further embodiment of document 1. Document 1 has an LED element 8 for implementing a security feature. LED element 8 is connected to an antenna 9. Antenna 9 serves to supply electrical energy for LED element 8. To do this, antenna 9 converts the energy of an electromagnetic field of an external transmitter into electrical energy to supply voltage to LED element 8.

Preferably, the antenna 9 is designed in such a way that it is tuned to the transmission frequency of a conventional mobile phone 10. If the document 1 is brought close to the antenna of the mobile phone 10, a corresponding electromagnetic field is coupled into the antenna 9, so that the LED element is supplied with voltage.

is provided and lights up. In this way, a "public feature" can be realized.

Preferably, the antenna 9 is designed as a Hertzian dipole antenna and printed on the carrier of the LED element 8, so that the module consisting of the LED element 8 and the antenna 9 can be integrated into the document 1 as a uniform layer, for example in the form of an inlay.

Figure 4 shows the optimal half dipole length of such a Hertzian dipole antenna in cm as a function of the frequency in Hz. If a common mobile radio frequency of 900 MHz is used, the half dipole length is 8.3 cm; if the mobile radio frequency of 1.8 GHz is also common, the half dipole length is 4.2 cm. Preferably, the half dipole length is in a range of approx. 3 - 5 cm or in a range of approx. 7 - 10 cm.

Figure 5 shows a further embodiment of document 1. Document 1 contains groups of LEDs 11 which are connected to antennas 16 via lines 12. Each antenna 16 has a half dipole length L for coupling in a transmission frequency. As soon as an electromagnetic field is coupled in, to which the antennas 16 are tuned, the LEDs 11, which are connected to the antenna 16 via the lines 12, are supplied with voltage and light up.

Furthermore, there are groups of LEDs 14 on the document 1, which are connected to one another via lines 15 and each to an antenna 13. Each antenna 13 has a half dipole length of 1 to couple in a higher transmission frequency compared to the antennas 16. If the document 1 is in a corresponding electromagnetic field, enough energy is coupled in via the antenna 13 to supply the LEDs 14 with voltage via the lines 15 and thus make them light up.

In the embodiment of Figure 5, each group of LEDs 11 or LEDs 14 is connected in parallel so that the same voltage is applied to each OLED in a group.

Preferably, the LEDs 11 and the LEDs 14 have different colors. For example, if the document 1 is brought into the range of a transmitter that "sweeps" through the relevant frequency range, the LEDs 11 and the LEDs 14 light up alternately in different colors.

When the relevant frequency range is scanned quickly, the different colors overlap. A specific "verification transmitter" with fixed or "sweeping" transmission frequencies can be used for this, so that different groups of LEDs can be lit in a selectable rhythm.

For example, groups of red, blue and green LEDs can be present on document 1 to achieve an RGB color mix. The LEDs of a certain color are each connected to one or more antennas that are tuned to the same color-specific transmission frequency. By quickly scanning through the frequency ranges to which the various color-specific antennas are tuned, an additive mixed color can be created by superimposing the color intensities.

Basically, there are different implementation options for the "verification transmitter":

The transmitter has fixed frequencies that are tuned to the corresponding antennas on Document 1. The different transmission frequencies are switched on selectively to check the presence of the corresponding LED group by lighting up these LEDs.

The transmitter traverses a frequency continuum which contains the frequencies to which the various antennas on the document 1 are tuned.

ft ·-# “»ft · ·· »·

This also makes the LEDs of the different groups light up.

Depending on the switching frequency of the different transmitter frequencies or the speed at which the frequency continuum is traversed, the effect is that different groups of LEDs light up at different times or, due to eye inertia, a mixed color results when switching quickly or traversing the frequency continuum quickly.

Another possibility is to connect one or more LEDs to two or more antennas of different lengths for differentiated frequency tuning, so that the LEDs light up twice during each switching cycle or each time the frequency continuum is passed through.

Figure 6 shows an embodiment of the document 1 in which a metal thread 17 is used for the voltage supply of the LED element 18. Such a metal thread 17 is often present, for example, in banknotes as a security thread that becomes visible in backlight.

In the embodiment of Figure 6, the metal thread 17 is interrupted in order to create a Hertzian dipole antenna. The two antenna poles created by the metal thread 17 are connected to the LED element 18 for its power supply. In this way, a particularly high level of security can be achieved by the metal thread 17 serving as a security thread on the one hand and having the function of lighting up the LED element 18 on the other hand in order to create an additional "public feature".

Figure 7 shows the document 1 of Figure 6 in the area of the LED element 18 - here designed as an OLED element - in section. The document 1 has a carrier 35, for example made of paper. The LED arrangement is limited at the bottom by an encapsulation layer 21. This can be a glass layer or a plastic film, for example. The metal thread is located above the layer 21.

17 (see Figure 6), which is interrupted in the area of the LED element 18 in order to create a Hertzian dipole. The LED element 18 contains a photoactive layer 19. The photoactive layer 19 extends into the area of the interruption of the metal thread 17, so that a voltage is applied to the photoactive layer 19 as soon as an electromagnetic field is coupled in via the metal thread 17. The photoactive layer 19 consists, for example, of conductive polymers, methanefullerenes, poly 3 hexyltriphenes or the like.

Above the photoactive layer 19 there is an electrode layer 20. The electrode layer 20 can consist of gold or another sputtered metal layer, for example, and serves to take on the function of the counter electrode and is preferably designed as a half-sided Hertzian dipole antenna. In the embodiment of Figure 7, however, it only serves to establish contact between the photoactive layer 19 and the second part of the Hertzian dipole antenna 17. The metal thread 17 thus performs the function of the counter electrode. An ITO layer, for example an ITO film, or a sputtered metal layer or the like can also be used as a material for the counter electrode.

The LED element 18 is limited at the top by a further encapsulation layer 36.

The various layers in the document 1 are designed such that light can be emitted from the photoactive layer 19 either upwards, downwards or in both directions from the surface of the document 1. For this purpose, for example, the carrier 35 and the encapsulation layer 21 and/or the electrode layer 20 and the further encapsulation layer 36 are designed to be transparent.

Figure 8 shows an alternative layer structure of the document 1. From top to bottom, the document 1 consists of a top laminate 24, a layer 25 for one or more LEDs and one or more energy sources, a carrier layer 26 and a bottom laminate 27.

The top laminate 24 serves as protection against mechanical influences and consists of a polyester (PET) layer 28 and a polyethylene (PE) layer 29.

The layer 25 also has - from top to bottom - a PE layer 29 with a thickness of, for example, 25 μm. This is followed by the encapsulation layer 21 with a layer thickness of no more than 100 μm. This is followed by the photoactive layer 19 including electrodes on both sides with a layer thickness of approximately 300 nm to a maximum of a few μm.

The photoactive layer 19 is followed by a layer 30, which consists for example of glass or a plastic film. The layer 30 in turn serves to encapsulate against oxygen and water. This is followed by another PE layer 29.

One or more LEDs are therefore implemented on the layer 30 by the photoactive layer 19. Furthermore, energy sources (see solar cell 6 in Figure 2, as well as the antenna 9 in Figure 3, the antennas 13 and 16 in Figure 5 and also the metal thread 17 in Figure 6) can also be applied to the same layer 30. It is also advantageous to implement the galvanic connection of the photoactive layer 19 with the energy source(s) on the layer 30.

The carrier layer 26 is, for example, a structure as is known from conventional identity cards. For example, the identity card document 23 is encapsulated at the top and bottom by a PE layer. The identity card document 23 is, for example, an insert made of special paper. The layer thickness of the identity card document 23 is approximately 100 μημ, while the layer thicknesses of the delimiting PE layers are each approximately 50 μημ.

The sub-laminate 27 in turn consists of a PE layer 29 and a PET layer 28. This in turn forms a protective layer.

The materials for the layer structure of document 1 are selected such that at least in one window area there is transparency with respect to the photoactive layer 19 (of the LED and possibly the solar cell), so that the light emitted from there can be emitted upwards, downwards or in both directions.

According to a further embodiment, a further security feature, for example in the form of a film with hologram structures, can be located between the PE layers 29 of the layer 25 and the carrier layer 26. Such a further security feature can, for example, alternatively or additionally be located between the identity card document 23 and the PE layer 29 or between two adjacent PE layers 29.

Preferably, the carrier layer 25, on which the LED elements and the energy sources are located, is first manufactured separately and then incorporated into the document 1 as an inlay in a lamination process. The very good barrier properties of the carrier material layer 30 and the cover layers against oxygen and ambient moisture ensure good long-term stability of the functionality of the LED and the energy sources. A particularly good long-term stability of approx. 30,000 operating hours is achieved with a glass carrier and glass cover layer. This results in layer thicknesses of approx. 100 to 200 μm for the entire functional layer structure (carrier layer 25), which is to be integrated into the document 1.

Figure 9 shows a block diagram of a system for checking a security feature, which is provided by an LED element on the document 1. In the application case of Figure 9, the LED element is a personalized LED matrix 7 (see Figure 2). Through personalization, biometric features of a person are displayed in the LED matrix 7.

The system has a biometric recognition system 31. This can be, for example, a system for obtaining biometric features from a person's face, iris or fingerprint.

The biometric recognition system 31 is connected to a camera system 33 via a line 32. The camera system 33 is used to record the light pattern generated by the LED matrix 7. The light pattern of the LED matrix 7 recorded by the camera system 33 is transmitted via the line 32 to the biometric recognition system 31 and compared there in a comparator 34 with the biometric data of the person in question.

In one application, the document 1 is an ID card. For access or border control, a person must identify themselves using the ID card. This is done by placing the document 1 underneath the camera system 33 so that the biometric data encoded in the LED matrix 7 is transmitted via the camera system 33 and the line 32 to the biometric recognition system 31. The camera system preferably includes a CCD camera.

In addition, the biometric data is recorded directly from the person by the biometric recognition system 31, for example by means of facial recognition, iris scanning or by recording the fingerprint. The biometric data determined directly from the person are then compared in the comparator 34 with the biometric data encoded in the LED matrix.

If there is a sufficient match between the biometric data recorded directly from the person and the biometric data stored in the LED matrix 7, the person in question is considered to be identified and the true bearer of the identity card. The system then emits a corresponding visual and/or acoustic signal, for example via the display 38. In this way, access or border control can be carried out automatically.

In addition to or as an alternative to the biometric data, the LED matrix 7 can also contain other data, such as the name, address, date of birth and other personal data in coded or uncoded form.

The camera system 33 also has an energy source 37, for example in the form of a light source and/or a transmitter. The light source and/or the transmitter serve to emit energy for the passive energy source of the document 1 in order to light up the LEDs of the LED matrix.

The system of Figure 9 can also be used if the LED element is not designed as a personalized LED matrix, for example for reading corresponding security features on packaging and the like. In this case, a system for character recognition can be provided instead of the biometric recognition system 31.

The wavelength of the light as energy source 37 is preferably selected so that the solar cell of document 1 works particularly efficiently, so that the LEDs shine particularly brightly or can only exceed their excitation threshold through the special selection of the wavelength of the light. In this way, in addition to a public feature, a security feature can be implemented which can only be checked using the system of Figure 9.
