elements the following embodiments, which correspond to each other, are each identified by the same reference numerals.

The 1 shows a document 100 in a schematic plan view. At the document 100 it may be a paper and / or plastic based document, in particular a value or security document, such as an identity document.

The document 100 has an integrated display device 102 , wherein it is in the display device 102 to act as a so-called active or passive matrix display. The display device 102 has a number of n row lines Z0 to Zn-1 and a number of m column lines S0 to Sm-1.

The Row lines are each equidistant in the row direction and the column lines equidistant in the column direction arranged. Alternatively, the distance between two adjacent ones Row lines and the distance between two adjacent column lines be different.

Through the row lines and the column lines, a matrix is formed. At the intersections of the row lines and the column lines are display elements of the display device 102 arranged, which can be controlled by driving the row line and the column line, which forms the respective intersection point.

The document 100 has a driver circuit 104 for selecting the row lines and the column lines for driving the display elements of the display device 102 , The document 100 also has an integrated electronic circuit, ie a so-called chip 106 , The driver circuit 104 can be an integral part of the display device 102 or the chip 106 form. You can also, as in the 1 shown to be formed as a separate component, both with the chip 106 as well as with the display device 102 is connected via signal lines.

The chip 106 has a data store 108 for storing data stored on the display device 102 should be reproduced. This may be, for example, facial image data 110 and / or graphical data of a carrier of the document 100 act as well as text data 112 , such as textual information about the carrier of the document 100 such as date of birth, place of residence, size or the like. Alternatively or in addition to the graphic data 110 and the text data 112 may also be data for reproducing a two- or three-dimensional bar code or the like in the data memory 108 be saved.

The chip 106 includes a processor 114 for executing program instructions 116 , By executing the program instructions 116 the processor reads the face image data 110 and / or the text data 112 from the data store 108 and passes it to the driver circuit 104 for a corresponding control of the display device 102 so the facial image data 110 and / or the text data 112 be reproduced.

The chip 106 can with an interface 118 be connected. the interface 118 can be contact-based, contactless or designed as a so-called dual mode interface. In particular, it may be at the interface 118 to act as 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. For contactless coupling via an antenna, this 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 for communication with an external device, such as a document reader 100 , In particular, the interface can 118 be designed so that an external reader on in the data memory 108 stored data, in particular biometric data, read access. As a condition for such a read access, the previous implementation of a so-called Basic Access Control (BAC) method and / or Extended Access Control (EAC) method can be provided.

Preferably, the display device is 102 designed flexible and flexible. The electrical and electronic components of the document 100 such as the interface 118 , the chip 106 and / or the driver circuit 104 , can print completely or partially on a document body of the document 100 be applied to maximum flexibility of the document 100 to enable.

In addition to those in the 1 shown components of the document 100 may have this element of the value or security printing, in particular applied by printing security features. Examples include tactile properties of intaglio printing or the tilt effect with optically variable colors. In printing and security printing, special inks are generally used to ensure distinctness. Thus, for example, personalization data introduced by means of ink-jet printing is secured by means of fluorescent inks, for example.

The document 100 For example, the standard ICAO 9303 for machine - readable travel documents based on the ISO 14443 A / B correspond. the interface 118 is then designed for high frequency communication at 13.56 MHz with an external reader.

The display device 102 can be a relatively high resolution for a brilliant black and white or Color rendering, in particular the facial image data 110 , exhibit. On the other hand, for the reproduction of the text data 112 only a lower resolution required. To the required effort for the complexity of the driver circuit 104 The procedure is to reduce groups of row lines and groups of column lines of the display device 102 can be determined 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 of the same group are shared only by the driver circuit 104 are selectable. In addition to the complexity of the driver circuit, this also reduces the volume of data required for the control.

In a first embodiment, such a definition of groups is achieved by electrical contacts between the row lines and the column lines of the same group. In the embodiment considered here, the column lines S0, S1 and S2 are electrically contacted 120 interconnected so that they are electrically at the same potential. These column lines S0, S1, S2 thus form a group which is only shared by the driver 104 can be controlled by, for example, on only one of the column lines S0, S1 or S2 of this group, a control signal through the driver circuit 104 is created. By means of such a control signal all column lines of this group are selected. The same applies to the column lines S3, S4 and S5, which are connected by a contact 122 and the column lines S6, S7 and S8 connected by a contact 124 be connected to each other.

Further, through the contacts 126 . 128 and 130 Sets of row lines, namely, a group including the row lines Z0, Z1 and Z2, a group including the row lines Z3, Z4, Z5 and a group including the row lines Z6, Z7 and Z8.

By this grouping of row lines and column lines is in the display device 102 an area 132 set that has a lower resolution than the remaining area of the display device 102 having. In the embodiment considered here, the resolution is in the range 132 a ninth of the resolution of the area 133 top right of the display device 102 because each nine display elements are combined to form a controllable 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 to play the text data 112 the groups of row and column lines of the area 132 be driven, 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 controlling the outside of the area 132 located display elements of the display device 102 he follows.

Alternatively to a definition of the groups of row lines and column lines via the electrical contacts 120 to 130 can in the driver circuit 104 an assignment table 134 or a similar-content mapping rule that implements this mapping of row wirings and column wirings into groups at a logical level. For example, if the driver circuit 104 generates a signal for selection of a column line, which is assigned to a certain group of column lines logically, so automatically more signals for the selection of the other column lines of the same group by the driver circuit 104 generated. The same applies to the control of the row lines for which a group membership in the allocation table 134 is fixed.

From only a relatively few stored data, the driver circuit 104 So by a multiple use of the same data fill a high-resolution display. For this purpose, a stored pixel information about the driver logic of the driver circuit 104 sent to, for example, two, four or more real existing display elements, and thus the actual resolution of the display device 102 lowered. Instead of the allocation table 134 can also be a fixed algorithm in the driver circuit 104 be programmed, which groups together various display elements or row lines and / or column lines for collective control.

The invention thus 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 displayed, due to the collective driving of the row wirings and column wirings in the area 132 is required.

This reduced data volume is particularly advantageous when it comes to the chip 106 is an RFID chip, as in such RFID chips, the available storage space of the data storage 108 is generally very limited. Of particular advantage here is also that the personalization, that is, the storage of the data in the data memory 108 , can be done faster, as this has the relatively slow RFID interface 118 respectively got to.

Another particular advantage is that by the definition of 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. By the specific assignment of the row lines and column lines to groups, the display device differs 102 of standard display devices 102 , especially if this assignment at the physical level by the introduction of contacts 120 to 130 he follows. This provides additional protection against manipulation of the document 100 given, about against that the display device 102 in the document 100 by another identical display device 102 is exchanged.

The 2 shows a schematic, not to scale plan view of a display device 102 with, for example, m = 25 and n = 25 display elements, ie 625 so-called pixels. The display device 102 is produced, for example, as a standard component. In a practical embodiment, m and n can be much larger.

The 3 shows the display device 102 after an individualization. The individualization was carried out here in such a way that the column lines S0 to S23 have been combined in pairs into column groups (SG), ie the column lines S0, S1 form the column group SG0, the column lines S2, S3 the column group SG1, etc. The row lines are analogous Z0 to Z24 have been combined in pairs to form row groups (ZG), ie the row lines Z0, Z1 to ZG0, the row lines Z2, Z3 to ZG1, etc.

By this definition of groups of row wirings and column wirings result ranges of different resolution of the display device, namely areas of high, medium and low resolution. The quadrant on the top left has QI and the quadrant on the bottom right has QIII each a mean resolution, whereas the quadrant QIV on the lower left and QII on the upper right quadrant have high resolution.

For example, serve the display elements of the display device 102 arranged in the quadrant QII for reproducing the face image data 110 (see. 1 ) with maximum resolution, whereas the middle resolution areas, ie, quadrants QI and QII, serve to reproduce textual information, and the low resolution area QIV is for bar code reproduction.

The realization of the combination of the row lines and the column lines into the groups SG and ZG can take place at the physical level by electrical contacts or at the logical level by an allocation table or an assignment rule, as described above with reference to FIGS 1 already explained.

The 4 shows an embodiment for the realization of the groups of row lines and column lines by pairwise electrical connection by means of the contacts 120 . 122 . 124 , ... the row lines S0 to S23 and by contacting the row lines Z0 to Z24 using the contacts 126 . 128 . 130 , ...

The 5 shows an embodiment of the display device 102 with four separate matrices MI, MII, MIII and MIV, each having separate and electrically isolated row lines and column lines. By pairing the row lines and the column lines of the matrix MIV is in the display device 102 a region of lower resolution than in the regions of the matrices MI, MII and MIII created, as in 6 shown. The advantage of this embodiment is that no distorted resolution can result in the medium resolution areas.

In another embodiment, 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 in the area 132 gives a monochrome display.

In addition, the resolution can also be in the range 132 can be reduced by further combining the column groups and the row groups of the display elements of the picture elements into larger collectives. This is especially beneficial when in the field 132 Text data in black and white, whereas the remaining area of the display device 102 for a brilliant reproduction of the facial image data 110 provided in color.

In a further embodiment, the display device 102 designed for autostereoscopic production of three-dimensional images. For this purpose, it is necessary that the display device 102 can reproduce two different images from different angles, so that each pixel is at least twice perform. On the display device 102 For example, a lens or line structure can be arranged to produce the three-dimensional impression in the viewer, as can be seen from the WO 2007/048855 A1 and the other prior art mentioned therein.

If in the area 132 only text data 112 are output, so there is a three-dimensional rendering is not required. 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 training of contacts 120 to 130 (See the embodiments of the 1 . 4 and 6 ) can be achieved by applying a conductive ink, for example, by inkjet or screen printing or other known printing method, such as high, low, through, flat and digital printing. Alternatively, there is an insulating polymer between the row lines and the column lines of the display device. The electrical contacts 120 to 130 are then prepared by irradiating the insulating polymer with a laser beam, since the insulating polymer is thereby transformed by carbonation into a conductive compound.

Alternatively, in the manufacture of the display device 102 all of the row lines and the column lines are contacted by fuses. For individualization of the display device 102 Selected of these fuses are opened electrically by a short-term current is applied there, which leads to the melting of the respective fused contact.

Alternatively, in this embodiment, not all 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 only has a low resolution. The resolution of the display device 102 can then be locally increased by selectively removing these contacts.

The 7 shows an example of the contact 120 (see. 1 . 4 and 6 ) between the column lines S0 and S1. The display device 102 is first prepared so that the contact 120 already exists. For individualization of the display device 102 can the contact 120 be removed, for example by laser ablation. Alternatively, a voltage is applied briefly between the column lines S0 and S1, which leads to the fact that the contact 120 melts, so that the column lines S0 and S1 are then no longer electrically contacted and therefore can be controlled individually.

The 8th shows the representation of 7 after the contact 120 has been severed.

The individualization of the display device 102 ie the definition of groups of the row lines and / or column lines for the collective control of the relevant display elements can, before, during or after the introduction of the display device 102 in the document body of the document 100 respectively. In particular, the individualization of the display device 102 in the production of blanks of the document 100 respectively. These document blanks can then be personalized at a later date with the personal details and biometric data of the document's bearer.

Alternatively, the individualization of the display device takes place 102 along with the personalization.

The 9 shows an embodiment of the document 100 , wherein by the definition of groups of the row lines and / or column lines, a pattern is given, which is used as a security feature. For example, the contact of the column lines S0, S1; the column lines S2 is not assigned to a group; through the contact 122 a group consisting of the column lines S3, S4 and S5 is set; through the contact 124 a group consisting of S6, S7, S8, S9 and through the contact 124 a group consisting of S10 and S11.

With respect to the row lines are through the contacts 126 . 128 and 130 Groups of row lines Z0, Z1, Z2 and Z3, Z4, Z5, Z6 and Z7, Z8 formed. Through this irregular combination of column lines and row lines into groups, a pattern is given, using a reader 136 is verifiable. The reader 136 has an optical sensor for this purpose 138 for optically detecting the display device 102 , The reader 136 also has a control program 140 with program instructions for processing of the optical sensor 138 supplied data as well as an application program 144 , The reader 136 also has an interface 146 for communication with the interface 118 of the document 100 , For example, contactless via an RFID method.

To check the given by the definition of groups security feature is the display device 102 with the help of the optical sensor 138 optically read, for example by the electrical contacts 120 to 130 even optically be captured or by a reference image on the display device 102 is issued, in which this grouping comes to light. The of the optical sensor 138 supplied data are provided by the program instructions 142 processed and compared with a reference value. In accordance with the reference value is the control program 140 a corresponding signal to the application program 144 off to the authenticity of the document 100 display. The application program 144 can then over the interfaces 146 and 118 on the chip 106 of the document 100 access.

The document 100 may have additional security features provided by the reader 136 also be tested. Further, a BAC and / or EAC protection mechanism may be implemented to be in the chip 106 to protect stored data.

In an alternative embodiment, the definition of the groups is not by the electrical contacts 120 to 130 but by the assignment rule 134 , This assignment rule 134 is also in the control program 140 available as a reference. Alternatively, the assignment rule 134 from the control program 140 be specified. This can be done so that the assignment rule 134 over the interfaces 146 . 118 to the driver 104 is transmitted.

The 10 a corresponding flow chart. In the step 200 becomes the display device 102 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 in the step 202 compared by the reader with a reference value. If there is no sufficient match, it is done in the step 204 the cancellation, ie the document is rejected as not authentic. In the opposite case, the security feature in the step 206 considered fulfilled. In order for the document to be considered authentic, additional security features may additionally be present which can also be checked.

The 11 shows an alternative embodiment of an authentication method according to the invention. In the step 300 the reader transmits an assignment prescription 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. In the step 302 For example, a reference image stored in the data memory of the chip is reproduced on the display device on the basis of this assignment rule. In the step 304 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.
