At least some of the row lines and / or column lines are assigned to groups. The row lines and / or column lines of the same group can only be selected jointly by the electronic circuit.
- Embodiments of the invention are particularly advantageous since a display device can be adapted to the image information to be displayed by the definition of groups. For example, if a face image is to be output in a first area of the display device and textual information is to be output in a second area of the display device, the invention makes it possible to adapt the image resolutions in the first and second areas of the display device accordingly, i. to choose a high image resolution in the first region and a low image resolution in the second region.
- the cost of implementing the driver logic for the display device can be reduced. Furthermore, this also reduces the space required for storing the image data.
- the efficient use of the driver logic and the available memory space due to the locally varying image resolution means that only a relatively small circuit area is needed to realize a driver for the display device. This is advantageous for the integration of the electronic circuit in the document.
- BNd Scheme here all data understood that are intended to produce a Biiddabe on the display device of the document, so for example the data of a digital photograph, a scanned biometric feature, a barcode, a text to be displayed, or other information.

- Embodiments of the invention also have the advantage that the definition of groups of the row lines and / or column lines gives a security feature which can be used to authenticate the document.
- the definition of the groups of row lines and / or column lines is effected by electrical connections.
- These electrical connections can be made by conductive inks applied, for example, by ink jet or screen printing between the row lines and / or column lines to be associated with each other.
- Other high, low, through, flat, and digital printing techniques may also be used to apply the conductive inks.
- the formation of the electrical contacts by means of a laser can be done.
- a conductive connection is made from an insulating polymer located between the row lines and / or column lines.
- the row lines and / or column lines are connected to one another by fusible contacts, that is to say so-called fuses.
- the definition of the groups of row lines and / or column lines then takes place in such a way that selected fuses are burnt out by applying corresponding voltages there in order to selectively remove the electrical contacts between the row lines and / or column lines.
- the definition of the groups of row lines and / or column lines takes place on a logical level by an assignment rule.
- the electronic circuitry of the document may be programmed with the mapping rule to implement the desired definition of the groups of row lines and / or column lines.

- the electrical circuit is a drive circuit for the display device.
- the driver circuit may form an integral part of the display device itself, it may be part of a chip implanted in the document, in particular an RFID chip or as a separate component part of the circuit.
- the display device may comprise picture elements each having at least three display elements for a color reproduction. Each of the display elements of a given pixel is connected to a separate row and column line. In order to form regions of the display device for black-and-white reproduction, the row and column lines of the display elements of picture elements in this black-and-white display area are combined into groups, which can each be activated only together.
- the reproduction of textual information or a bar code such as a 2D or 3D bar code is performed, whereas in the remaining display area, a color photograph is reproduced.
- the driver logic can be simplified and the data volume required for driving the display device is reduced.
- the invention relates to a method for authenticating a document.
- the invention utilizes the fact that the definition of groups of the row lines and / or column lines simultaneously provides a security feature. Authentication of the document is based on this security feature.
- the definition of the groups takes place through the formation of electrical contacts between the row lines and / or column lines. These contacts are optically detected by a reader. The pattern thus detected is compared with a reference pattern to check the authenticity of the document.
- the definition of the groups takes place on a logical level by an assignment rule.
- the authenticity of the document is checked using the assignment rule.
- this is an assignment rule from a reader to the electronic circuit of the document. Based on this mapping rule, the electronic circuit then drives the display device to render an image. This image is optically captured and evaluated by the reader to verify the authenticity of the document.

- the specifications of various states may differ as to the display of image information on the display device.
- a first state may require a facial image to be rendered at the top left of the display, whereas a second state may require that the playback is done on the bottom right. Accordingly, the individualization of the display devices takes place depending on the application.
- the individualization of the display devices can take place on the occasion of the production of document blanks.
- the document blanks with the individualized display devices are issued, for example, at identification points, which personalize the document blanks on the basis of the personal data of the citizen for which the identity documents are to be issued.

- the document 100 further has an integrated electronic circuit, i. a so-called chip 106.
- the driver circuit 104 may form an integral part of the display device 102 or the chip 106. It may also, as shown in Figure 1, be formed as a separate component which is connected to both the chip 106 and the display device 102 via signal lines.
- the chip 106 has a data memory 108 for storing data to be displayed on the display device 102.
- This may be, for example, facial image data 110 and / or graphical data of a user of the document 100 as well as text data 112, such as textual information about the user of the document 100, such as date of birth, place of residence, size or the like.
- text data 112 such as textual information about the user of the document 100, such as date of birth, place of residence, size or the like.
- data for reproducing a two- or three-dimensional barcode or the like may also be stored in the data memory 108.
- the chip 106 includes a processor 114 for executing program instructions 116.
- the processor By executing the program instructions 116, the processor reads the face image data 110 and / or the text data 112 from the data memory 108 and passes them to the driver circuit 104 for a corresponding drive of the display device 102 such that the face image data 110 and / or the text data 112 are reproduced.
- the chip 106 may be connected to an interface 118.
- the interface 118 may be contact-based, contactless or designed as a so-called dual mode interface.
- the interface 118 may be a so-called RFID interface with an antenna.
- the interface 118 may be based on an electrical, capacitive, inductive, magnetic, optical or other physical coupling method.
- contactless coupling via an antenna it can be designed, for example, as a coil, dipole or in the form of capacitive surfaces.
- the interface 118 serves to power the chip 106, the driver circuit 104 and / or the display device 102 and / or to communicate with an external device, such as a reading device for the document 100.
- the interface 118 may be configured such that a external reader on data stored in the data memory 108, in particular biometric data, read access.
- BAC Basic Access Control
- EAC Extended Access Control
- the display device 102 is flexible and bendable.
- the electrical and electronic components of the document 100 such as, for example, the interface 118, the chip 106 and / or the driver circuit 104, can be completely or partially applied to a document body of the document 100 in order to allow maximum flexibility of the document 100 enable.
- these elements may have the value or security printing, in particular security features applied by means of printing methods. Examples include tactile properties of intaglio printing or the tilt effect with optically variable colors.
- special inks are generally used to ensure distinctness.
- personalization data introduced by means of ink-jet printing is secured by means of fluorescent inks, for example.
- the document 100 may conform to the ICAO 9303 machine readable travel document standard based on ISO 14443 A / B.
- the interface 118 is then configured for high frequency communication at 13.56 MHz with an external reader.
- the display device 102 may have a relatively high resolution for brilliant black-and-white or color rendering, particularly the facial image data 110 or a symbol.
- the high resolution may also be required for the optical output of information, in particular a driving parameter or a charging status, with a relatively high data rate.
- only a lower resolution is required for the reproduction of the text data 112.
- groups of row lines and groups of column lines of the display device 102 are set by assigning the row lines and the column lines of the same group to each other such that the row lines and the column lines the same group can only be selected jointly by the driver circuit 104. In addition to the complexity of the driver circuit, this also reduces the volume of data required for the control.
- such a definition of groups is achieved by electrical contacts between the row lines and the column lines of the same group.
- the column lines SO, S1 and S2 are connected to each other by an electrical contact 120, so that they are electrically at the same potential.
- These column guides So SO, S1, S2 thus form a group which can be driven only together by the driver 104, for example by applying a control signal to the driver circuit 104 on only one of the column lines SO, S1 or S2 of this group.
- a control signal all column lines of this group are selected.
- the column lines S3, S4 and S5 which are connected to one another by a contact 122
- the column lines S6, S7 and S8, which are connected to one another by a contact 124.
- groups of row wirings are set, namely a group including the row wirings Z0, Z1 and Z2, a group including the row wirings Z3, Z4, Z5 and a group including the row wirings Z6, Z7 and Z8.
- a range 132 is defined in the display device 102, which has a lower resolution than the remaining area of the display device 102.
- the resolution in the region 132 is one-ninth of the resolution of the region 133 upper right of the display device 102, since nine display elements are combined into one drivable pixel due to the grouping of the row lines and column lines, and one third of the resolution of the other areas.
- the driver circuit 104 is designed so that the groups of row lines and column lines of the area 132 are driven to reproduce the text data 112, which is possible due to the required small amount of data and low complexity of the control with little technical effort, whereas the face image data 110 by driving the display elements of the display device 102 located outside of the area 132 take place.
- an assignment table 134 or an assignment specification of the same content may be stored in the driver circuit 104, which assigns this assignment of row lines and column lines Implemented groups at a logical level. If, for example, the driver circuit 104 generates a signal for selecting a column line which is logically assigned to a specific group of column lines, further signals for the selection of the other column lines of the same group are automatically generated by the driver circuit 104. The situation is similar for the control of the row lines for which a group membership in the allocation table 134 is defined.
- the driver circuit 104 can thus fill a high-resolution display by multiple use of the same data.
- a stored pixel information is sent via the driver logic of the driver circuit 104 to, for example, two, four or more real existing display elements, and thus the actual resolution of the display device 102 is lowered.
- a fixed algorithm may also be programmed in the driver circuit 104, which groups together various display elements or row lines and / or column lines for collective control.
- the invention therefore makes possible a data reduction, in particular for the reproduction of the text data 112, since separate image information need not be stored for each pixel to be reproduced because of the collective control of the row lines and column lines in the region 132.
- This reduced data volume is particularly advantageous when the chip 106 is an RFID chip, since with such RFID chips the available memory space of the data memory 108 is generally very limited.
- the personalization that is, the storage of the data in the data memory 108, can be done faster because this must be done via the relatively slow RFID interface 118.
- a further particular advantage is that by defining groups of the row lines and the column lines, an individualization of the display Device 102 is given, which can be used as a security feature. Due to the specific assignment of the row lines and column lines to groups, the display device 102 differs from standard display devices 102, in particular if this assignment takes place on a physical level through the introduction of contacts 120 to 130. In this way, an additional protection against manipulation of the document 100 is given, for example against the fact that the display device 102 in the document 100 is replaced by another identical display device 102.
- the information output by the driver circuit 104 via the display device 102 may also be a vehicle parameter and / or a charge status.
- the information may be in the form of text data 112 and / or in lieu of the facial image data 110.
- the document 100 is embodied as an automotive electronic license plate attached to or forming an integral part of the motor vehicle.
- the driver circuit 104 or the chip 106 may have an interface to a motor vehicle electronic device which transmits the information to be output to the interface at regular or irregular intervals.
- the motor vehicle electronic device may be, for example, a so-called Electronic Control Unit (ECU).
- ECU Electronic Control Unit
- the motor vehicle electronic device can be networked with the interface via a motor vehicle bus system in order to transmit the information to be output via the motor vehicle bus system.
- the motor vehicle electronic device can be used to detect a vehicle parameter, on the basis of sensor signals.
- a sensor is used to detect a current exhaust gas value of the motor vehicle. This current exhaust gas value is transmitted in the form of information from the motor vehicle electronic device to the electronic circuit 104, so that the exhaust gas value is output via the display 102. Accordingly, for further vehicle parameters, such as, for example, the speed which is currently determined by the force vehicle-generated noise level or other environmental and / or safety-relevant vehicle parameters are moved.
- the motor vehicle electronic device is designed to determine a charging status. For example, it is determined by the motor vehicle electronic device whether a required fee, such as a toll, a tax, or an exhaust gas charge, has been paid for or paid for the motor vehicle. Corresponding information indicating the charging status is output by the motor vehicle electronic device to the electronic circuit 104, so that this information is output via the display 102. This can be done for example by displaying a charge sticker on the display 102.
- the reader 108 for detecting the information output via the display 102 may be formed by the stationary and / or the traveling motor vehicle.
- the reader 108 may be connected via a network to a central server computer in which the information captured by the display 102 is evaluated.
- the text data 112 may be the official motor vehicle license plate. Visually visible on the display 102, therefore, is the official motor vehicle license plate and, in addition, one or more further information items that can be perceived visually or imperceptibly without a reading device, depending on the embodiment.
- an update of the registration number may be performed by updating the text data 112, for example by sending data including the updated registration number to the interface from the automotive electronic unit via the automotive bus system.
- the display device 102 is used, for example, as a standard. standard component produced. In a practical embodiment, m and n can be much larger.
- FIG. 3 shows the display device 102 after individualization.
- the individualization was carried out here in such a way that the column lines SO to S23 were combined in pairs into column groups (SG), i. the
- Column lines SO, S1 form the column group SGO, column lines S2, S3 the column group SG1, etc.
- the row lines Z0 to Z24 have been combined in pairs to form row groups (ZG), i. the row lines Z0, Z1 to ZGO, the row lines Z2, Z3 to ZG1, etc.
- regions of different resolution of the display device result, namely areas of high, medium and low resolution.
- the upper left quadrant Ql and the lower right quadrant QIII each have a medium resolution, whereas the lower left quadrant QIV has a low resolution and the upper right quadrant QII has a high resolution.
- the display elements of the display device 102 arranged in the quadrant QII serve to display the facial image data 110 (see Fig. 1) at maximum resolution, whereas the medium resolution areas, i. the quadrants Ql and QII are for reproducing textual information and the low resolution area QIV is for playing a barcode.
- FIG. 4 shows an embodiment for the realization of the groups of row lines and column lines by pairwise electrical connection with the aid of the contacts 120, 122, 124,... Of the row lines SO to S23 and by contacting the row lines Z0 to Z24 with the aid of Contacts 126, 128, 130, ...
- FIG. 5 shows an embodiment of the display device 102 with four separate matrices Ml, MII, MIII and MIV, each having separate row lines and column lines electrically isolated from one another. By contacting the row lines and the column lines of the matrix MIV in pairs, a region with lower resolution is created in the display device 102 than in the regions of the matrices Ml, MII and MIII, as shown in FIG.
- the advantage of this embodiment is that no distorted resolution can result in the medium resolution areas.
- the display device is designed as a color display, so that realize at least three different display elements, for example, the colors red, green and blue one pixel. If the row lines and the column lines of the display elements belonging to the same picture element are each combined into groups, then the individual display elements of a picture element are no longer individual but only collectively controllable, so that a monochrome display results in the area 132.
- the resolution can also be reduced to the area 132 by further combining the column groups and the row groups of the display elements of the picture elements into larger collectives. This is particularly advantageous if in the area 132 text data are to be displayed in black and white, whereas the remaining area of the display device 102 is provided for a brilliant reproduction of the face image data 110 in color.
- the display device 102 is designed for the autostereoscopic generation of three-dimensional images. For this purpose, it is necessary for the display device 102 to be able to reproduce two different images from different viewing angles, so that therefore each image element is to be executed at least twice.
- On the display device 102 may be arranged a lens or line structure to produce the three-dimensional impression in the viewer, as is known per se from WO 2007/048855 A1 and the other prior art mentioned therein. If only text data 112 is to be output in area 132, a three-dimensional rendering is not required there. Therefore, in order to simplify the control and to reduce the data, the column lines and the row lines of two associated double-executed picture elements are combined there.
- the formation of the contacts 120 to 130 can be achieved by applying a conductive ink, for example by means of inkjet or screen printing or another known printing method, such as high-, low- , Through, flat and digital printing.
- a conductive ink for example by means of inkjet or screen printing or another known printing method, such as high-, low- , Through, flat and digital printing.
- the electrical contacts 120 to 130 are then produced by irradiation of the insulating polymer with a laser beam, since the insulating polymer is thereby transformed by means of carbonization into a conductive compound.
- all of the row lines and the column lines may be contacted by fuses.
- selected ones of these fusible contacts are opened electrically by briefly applying a current there, which leads to the melting of the relevant fused contact.
- not all the row lines and column lines are contacted with each other, but groups each having a plurality of row lines and column lines are formed so that the display device 102 initially has only a low resolution. The resolution of the display device 102 can then be locally increased by selectively removing these contacts.
- FIG 7 shows by way of example the contact 120 (cf., FIGS. 1, 4 and 6) between the column lines SO and S1.
- the display device 102 is first made so that the contact 120 already exists.
- the contact 120 can be removed, for example by laser ablation.
- a voltage that causes the contact 120 melts through, so that the column lines SO and S1 are then no longer electrically contacted and therefore can be controlled individually.
- FIG. 8 shows the illustration of FIG. 7 after the contact 120 has been severed.
- the individualization of the display device 102 i. the definition of groups of the row lines and / or column lines for the collective control of the affected display elements can take place before, during or after the insertion of the display device 102 into the document body of the document 100.
- the individualization of the display device 102 can take place during the production of blanks of the document 100. These document blanks can then be personalized at a later date with the personal details and biometric data of the document bearer.
- the individualization of the display device 102 takes place together with the personalization.
- FIG. 9 shows an embodiment of the document 100, wherein by defining groups of the row lines and / or column lines a pattern is given, which is used as a security feature.
- the contact of the column lines SO, S1; the column lines S2 is not assigned to a group; the contact 122 defines a group consisting of the column lines S3, S4 and S5; by the contact 124 a group consisting of S6, S7, S8, S9 and by the contact 124 a group consisting of SI O and S11.
- groups 126, 128 and 130 form groups of row lines Z0, Z1, Z2 as well as Z3, Z4, Z5, Z6 and Z7, Z8.
- This irregular combination of column lines and row lines into groups gives a pattern which can be checked with the aid of a reading device 136.
- the reading device 136 has an optical sensor 138 for optically detecting the display device 102.
- the reading device 136 also has a control system. program 140 for processing the data supplied by the optical sensor 138 and an application program 144.
- the reader 136 also has an interface 146 for communicating with the interface 118 of the document 100, for example contactlessly via an RF I D method.
- the display device 102 is optically read with the aid of the optical sensor 138, for example by optically detecting the electrical contacts 120 to 130 themselves or by outputting a reference image on the display device 102 in which this grouping comes to light.
- the data provided by the optical sensor 138 is processed by the program instructions 142 and stored with a reference value, i. a reference assignment compared.
- the control program 140 issues a corresponding signal to the application program 144 to indicate the authenticity of the document 100.
- the application program 144 can then access the chip 106 of the document 100 via the interfaces 146 and 118.
- the document 100 may include additional security features that are also tested by the reader 136. Further, a BAC and / or EAC protection mechanism may be implemented to protect the data stored in the chip 106.
- the definition of the groups is not given by the electrical contacts 120 to 130, but by the assignment process step 134.
- This assignment rule 134 is also present in the control program 140 as a reference.
- the assignment rule 134 may be specified by the control program 140. This can be done so that the assignment rule 134 is transmitted via the interfaces 146, 118 to the driver 104.
- step 200 the display device 102 is optically detected by the reader to optically detect the combination of the row lines and / or column lines into groups and the pattern formed thereby.
- This pattern is used in step 202 of FIG Reader compared with a reference value. If there is not a sufficient match, then in step 204 the abort occurs, ie the document is rejected as being not authentic. In the opposite case, the security feature is considered satisfied at step 206. In order for the document to be considered authentic, additional security features may additionally be present which can also be checked.
- FIG. 11 shows an alternative embodiment of an authentication method according to the invention.
- the reading device transmits an assignment rule to the driver of the document, for example by means of an RFID method.
- the assignment rule defines collectives of display elements, row lines and / or column lines which can only be controlled collectively.
- a reference image stored in the data memory of the chip is reproduced on the display device on the basis of this assignment rule.
- this image reproduction is detected by the reader and compared with a reference value for the purpose of verification. If the captured image matches the reference image, the security feature is considered satisfied.
