Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a document having an electronic display device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document having an electronic display device, for example, a valuable document or a secure document, in particular, an ID document or a bank card.

Documents with electronic integrated circuits are known in various forms from the prior art. For example, as a banknote, as a personal passport, in general paperized form, or as a plastic based chip card in a contact, contactless or dual interface embodiment, in particular a valuable or security document that exists as a so- exist.

Various radio recognition systems for such documents, also referred to as radio frequency identification (RFID) systems in particular, are known from the prior art. Existing known RFID-systems generally have at least one transponder and one transceiver unit. The transponder is also referred to as RFID-etiquette, RFID-chip, RFID-tag, RFID-label or wireless etiquette, and the transceiver unit is also referred to as a reader or reader. In addition, integration with servers, services, and other systems such as payment systems or commodity economics systems is often provided by so-called middleware.

Data stored in a contactless, e.g. RFID-transponder, is made available by radio waves. This is induced by the roots at low frequencies and by electromagnetic sources at high frequencies.

RFID-transponders are commonly equipped with microchips and antennas, which are housed in a carrier or housing or printed on a substrate. The active RFID-transponder additionally uses an energy source such as a battery as opposed to a passive transponder.

The RFID-transponder can be inserted into a chip card for various documents, in particular for realizing an electronic booking or an electronic wallet. It is also integrated into, for example, valuable documents or secure documents, especially paper or plastic such as banknotes and proof documents.

From DE 201 00 158 U1, for example, identity cards and security cards are known as laminated and / or injection molded plastics with integrated semiconductors having antennas for the implementation of RFID-systems. Also known from DE 10 2004 008 841 A1 is a book valuable document such as a passport book, for example with a transponder unit.

Such security documents or valuable documents are described, for example, in DE 10 2005 030 626 A1, DE 10 2005 030 627 A1, DE 10 2005 030 628 A1, WO 2004/080100 A1, EP 1 023 692 B1, DE 102 15 398 B 4, EP 1 173 825 B1, EP 1 230 617 B1, EP 1303835 B1, EP 1 537 528 B1, WO 03/030096 A1, EP 0 920 675 B1, US 6,019,284, U.S. Pat. 6,402,039 B1, WO 99/38117, incorporated herein by reference.

The security document or the valuable document may be equipped with a contact or non-contact interface, such as an RFID-interface and / or an interface that allows wireless communication as well as wired connection communications with the chip card-terminal, . In the case of wireless communication, it is also communicated by a so-called dual interface chip card. The chip card-communication protocol and method are specified, for example, in the ISO 14443 standard.

WO 2008/145505 A1 (the present invention originates from this document as the latest technology) discloses valuable documents or secure documents with display elements for reproduction of image sequences and operational elements for navigation in the image sequence , Wherein the operating element may be, for example, a slide switch having various lock-in positions, a swivel rod, a touch sensitive input system or other multifunction switch.

Images with capacitive trackpad from Baudisch, Pua: Back-of-Device Interaction Allows Creating Very Small Touch Devices, ACM CHI 2009 - New Mobile Interactions, 9. April - Boston, S. 1923-1932 Screen devices are known, which are arranged on the back side of the device and are mapped 1: 1 on the image screen.

On the contrary, an object of the present invention is to propose an improved document having an electronic display device, in particular a valuable document or a security document.

The object of the present invention is solved by the features of claim 1. Embodiments of the invention are disclosed in the dependent claims.

According to an embodiment of the present invention, a document is formed in a card-like form, for example, as a chip card. The electronic display may be disposed on or within the document body of the document so that the user can visually recognize the display generated by the display element on the front side of the document. For example, the display element is controlled by the processing means of the document to reproduce text data or other data such as, for example, photographs, barcodes and / or icons of a graphical user interface. For example, the display element is disposed on or in the document layer below the top layer of the document, and the top layer is transparent in at least the area of the display element.

However, the touch pad of the document is placed on or in the document body so that the user can manipulate the user to input a signal to the processing means on the back side of the document. For example, the touchpad-sensor is disposed on or in one layer above the lowest layer of the document that forms the back side of the document. The touch pad of the document is formed through the touch pad-sensor and the document layer or layers beneath it.

Embodiments of the present invention are particularly advantageous since the touchpad is disposed in the document body below the display element, so that the face used in the display on the front side is not reduced by the touchpad. This is particularly advantageous because the user does not cover the display element by manipulating the touchpad on the back of the document, allowing the user to visually detect the entire contents of the display during operation of the touchpad. This is particularly advantageous, for example, in card-type documents with standardized chip cards, since the available surfaces are small.

For example, a document according to the present invention may have dimensions in accordance with ISO 7816 or ISO 7810 and have, for example, one of the following formats:

ID-1 (check card format): 85.60 mm x 53.98 mm,

ID-2: 105 mm x 74 mm,

ID-3: 125 mm 88 mm,

ID-00: 66 mm x 33 mm,

ID-000: 25 mm x 15 mm or

Visa Mini: 65.6 mm x 40.0 mm.

The thickness of the document is 2 mm, preferably less than 1 mm, for example 0.76 mm.

According to one embodiment of the present invention, the surface detected by the touch pad on the back side of the document is larger than the side occupied by the display on the front side of the document. The document in this case comprises means for coordinate transformation between the reference system of the touchpad and the reference system of the input device. This coordinate conversion is performed using a lookup table that converts the input coordinates of the reference system of the touch pad represented by the calculation, in particular by estimation, or by the signal of the touch pad, to the coordinates of the reference system of the display element, in particular . As a result, the relatively long distance that the user moves with his / her finger inside the surface detected by the touch pad on the back side of the document corresponds to a relatively short distance on the display element, thereby facilitating handling of the document.

According to one embodiment of the present invention, the lowermost layer of the document forming the back side is printed. In particular, when using a capacitive or resistive touchpad-sensor, the bottom layer should be formed opaque, which is not necessary for sensing the finger position.

According to an embodiment of the present invention, a document can be a paper-based and / or plastic-based document, in particular a valuable document or a secure document, such as a proof document, in particular a passport, identification, visa or driver's license, vehicle registration certificate, Health card or other ID-document or chip card, means of payment, in particular banknotes, bank cards or credit cards, courier or other credentials. The document has a carrier (substrate) made of, for example, paper or plastic on which additional layers can be applied, for example, print technology.

According to an embodiment of the present invention, the display element can be a bistable display, an electrophoretic display, an electrochromic display, a liquid crystal display (LCD), an LED-display, especially an inorganic LED- or organic LED-display (OLED) Display, a photoluminescent-erasing display, or a display based on an electrowetting effect or a hybrid display.

Refers to any device capable of sensing the position of a user's finger with the aid of a touchpad-sensor within the face detected by the touchpad, wherein the touchpad- And emits a corresponding signal indicating the coordinates of the position inside the surface detected by the touch pad. The touchpad may act on all known sensor principles that may require touching or pressure of the finger on the touchpad or may be operated in a non-touch manner. For example, the touch pad may be formed in a resistive or capacitive manner. In particular, the touch pad may also be a multi-touch touch pad capable of sensing by two or more fingers at the same time. These touch pads are also referred to as track pads. The "touch pad" also means a coordinate input device in which the coordinates of the stylus are detected, for example, by capacitive or electromagnetic coupling.

According to one embodiment of the present invention, the display element and the touch pad form a structural unit disposed on or in the layer of the document body.

According to one embodiment of the present invention, a user can use a touch pad to determine the position of a cursor, i.e., a so-called pointer, displayed by a display element. The user can use the cursor to select a predetermined image element to be displayed on the display element, for example. Such an image element may be an indication of an element of the graphical user interface of the document, in particular a so-called computer icon. By selecting this icon displayed by the display element using the cursor, the user can select a predetermined function assigned to the icon executed by the later processing means.

According to one embodiment of the invention, the document comprises an electronic memory for storing a plurality of images forming an image sequence. The various images may be digital photographs of the user taken from various directions. The user can then navigate through the image sequence using the touchpad.

According to one embodiment of the present invention, the document comprises an operating element that can be manipulated by the user on the front side of the document for inputting additional signals to the processing means. Such an operating element may be, for example, a manipulator such as a press key, a slide, or the like.

According to one embodiment of the present invention, the user can confirm the activated selection by using the cursor in advance by operating the operation element, whereby the execution of the function assigned to the image element, for example, is started by the processing means. Thus, the functions of a computer mouse, in particular, can be used in a document, and the operation of the operating element is similar to a mouse click using a computer mouse. The user can manipulate the touch pad on the back side of the document with the index finger of his right hand, for example, to bring the cursor to a desired position on the display to select a particular image element, while the user places his thumb of his left hand on the front side of the document, So that it is particularly advantageous because it is convenient to handle.

According to one embodiment of the present invention, the display element is formed as a touch screen for inputting additional signals to the processing means. Like the document's touchpad, any known sensor principle can be used on the touch screen. The touch screen is designed to sense the position of the finger or stylus present on the element of the display on the front side of the document and input to the processing means. For example, the processing means may be designed such that a virtual operating element, for example a so-called button, is displayed on the display element, where such a button is activated by touching the display element at the position where the button is displayed, so that a further signal is input. Thereby, a function equivalent to the function of a separate operating element formed, for example, as a switch or a slide can be performed.

According to one embodiment, the document comprises a contactless interface for energizing multiple electronic and electronic components of the document, in particular for supplying energy to the display element and the touchpad. The contactless interface can be designed for inductive coupling of energy, in particular RFID- or NFC-standard.

Further, embodiments of the present invention will be described in more detail with reference to the drawings.

The corresponding elements in the following embodiments are denoted by the same reference numerals.

Figure 1 shows a schematic exploded view of one embodiment of a document 100 in accordance with the present invention. to be. Document 100 is a valuable or secure document such as an ID-document, passport, ID, driver's license, access card, credential, bank card, credit card,

The document 100 has a document body 146 having a layered structure. The front side of the document 100 is formed by the uppermost layer 148 which is a transparent laminate covering layer made of, for example, plastic. The back side of the document 100 is formed by the lowermost layer 150, which can also be a laminate coating layer made of plastic. The layer 150 may be printed on its entire surface, for example.

Between the layer 148 of the document body 146 and the layer 150 there is an additional layer, in particular a layer 152. Layer 152 includes electronic circuitry 104 disposed on or adjacent to display element 102 and layer 152 and next to display element 102 therein.

The display element 102 may be formed as an un-illuminated, a back illuminated, a front illuminated or a self illuminated. For example, the display element 102 is a bistable display element whose display can be permanently reproduced without energy supply. For example, if the document 100 is not energized or deactivated, for example, the user's facial image may be displayed at a particular angle on the bistable formed display element 102, for example. The layer 148 is formed at least in the interior of the area 154 that covers the display element 102 so that the image that the user reproduces on the display element 102 is projected onto the area 154 from the front side of the document 100. [ Can be visually recognized.

In the embodiment contemplated herein, a touch pad-sensor 156 is disposed below the display element 102. [ The touch pad-sensor 156 is substantially similar in shape and size to the display element 102 herein. For example, the display element 102 may be disposed on the top surface of the layer 152 and the touchpad-sensor 156 may be disposed on the bottom surface of the layer 152. However, the display element 102 and the touchpad-sensor 156 may form a structural unit or be arranged in different layers.

The touchpad-sensor 156 may be a resistive or capacitive touchpad-sensor. By incorporating the touchpad-sensor 156 in the document body 146, the touchpad-sensor 156 is sensitive to touch and / or access in the area 158 of the layer 150 covering the touchpad-sensor 156, A touch pad is implemented that emits a position signal 168 (see FIG. 2).

The document 100 comprises an electronic circuit 104. The circuit 104 is designed to control the display device 102 such that a predetermined display is created on the display device 102. In addition, the circuitry 104 is designed to receive position signals from the touchpad-sensors 156.

For example, the position signal may provide the coordinates of the position of the user's finger 160 actually sensed by the touch pad-sensor 156 in the area 150. [ For example, the position signal includes the XY-coordinate of the position of the finger detected in the reference system of the touch pad-sensor 156, herein a Cartesian coordinate system.

The position signal is processed by the electronic circuit 104. As a result of processing the position signal by the circuit 104, for example, the position of the cursor displayed on the display element 102 can be changed, so that the image or image element displayed on the display element 102 is selected, Depending on the location, another action is triggered.

2 shows a block diagram of an embodiment of a document 100 corresponding to the embodiment of FIG. The circuit 104 includes an electronic memory 110 in which, for example, text data 165 and / or image data 166 are stored. The text data 164 may be, for example, the owner of the document 100, i.e., information about the owner of the proof document and / or information about the authority that issued the document. Image data 166 may include other data that may be displayed on display device 102, for example, as a plurality of digital face images, two-dimensional bar codes, symbols, or images of the owner.

For example, image data 166 includes an image sequence consisting of images Bl - Bn, where, for each image, a corresponding image data set is stored in electronic memory 110 See form).

The electronic circuit 104 includes a processor 105 for execution of the program instructions 108. The electronic circuit 104 further includes a driver 106 that allows the processor 105 to control the display device 102 for reproduction of data stored in the memory 110. [

The processor 105 may receive a position signal 168 that indicates one or more positions actually sensed by the touchpad-sensor 156. The position signal 168 is evaluated by the processor 105 through execution of the program instruction 108 and the display element 102 generates a display determined by the driver 106 according to the evaluation result of the position signal 168 .

For example, the selection of data stored in the memory 110 may be performed by the position signal 168 to enable playback on the display device 102. [ In particular, the program instructions 108 may generate a graphical user interface that includes a predetermined image element displayed on the display element, in particular a so-called cursor, i.e. a pointer, from which an icon can be selected. The nominal position of the cursor is determined, for example, by the position of the finger 160 relative to the touchpad-sensor 156 and is communicated in the form of a position signal 168 of the touchpad- The display position of the cursor can follow the position signal 168. [

Figure 3 illustrates another embodiment of a document 100 in accordance with the present invention.

In this embodiment, the touch pad-sensor 156 has a larger surface than the display element 102. [ For example, the touchpad-sensor 156 covers the entire or nearly the entire area of the document 100, so that the area 158 covers the entire or nearly the entire layer 150. In the embodiment contemplated herein, the touchpad-sensor 156 is disposed in a separate layer 170, but may be disposed in the layer 152 as in the embodiment according to FIG. 1 and / or the display element 102 ) And a structural unit.

In this embodiment, since the area 158 and the area 154 are different in size and shape, a Cartesian coordinate system with a unique reference system of the display device 102, here coordinate axes X 'and Y', is defined. The position signal 168 supplied by the touch pad-sensor 156, including the actual X-, Y-coordinates of the position of the finger 160 relative to the coordinate system 162, is processed by the electronic circuit 104, The XY-coordinate of the coordinate system 162 is converted into the corresponding X'- and Y'-coordinates of the coordinate system 172. [ This can be done, for example, by touching or using a look-up table, and the XY-coordinate of the coordinate system 162 in the look-up table is represented by the X'- and Y'-coordinates of the coordinate system 172.

Maximizing the area 158 has the advantage that the handling of the document 100 is easier than in the embodiment according to FIG. Due to the relatively small document 100 design in general, fetching the finger 160 in the correct position in the area 158 in order to activate the function of the desired electronic circuit 104, e.g. in a check card format, To a given location may be relatively difficult for some older people. The position of the finger 160 is facilitated by enlarging the area 158 in accordance with the embodiment of FIG. 3, since the positioning need not be so accurate here.

In the embodiment of FIG. 3 contemplated herein, the document 100 further comprises a further operational element 174 that can be manipulated by the user on the front side, i.e., the layer 148. The operating element 174 is, for example, a push switch, a slide switch or another manipulating device. By operating the operating element 174, for example, a switching signal is input to the electronic circuit 104 and processed thereby.

This switching signal may be an acknowledgment signal for the selection of an image element performed by positioning the finger 160 in advance, similar to a mouse click by a computer mouse. The operating element 174 may in particular have the function of an enter key. Preferably, the operating element 174 is disposed at the edge of the document 100, particularly at the left or upper edge of the layer 148, preferably at the upper left corner of the layer 148, 160, the user holding the document 100 can easily reach the operating element 174 with the index of his left hand. In the left hand version, the actuating element 174 is preferably located at the right or upper edge of the layer 148, preferably at the upper right corner of the layer 148. Further, the operating element 174 is disposed at the left and right upper corners of the layer 148, so that the document can be handled equally easily with respect to the left and right hands.

FIG. 4 shows a block diagram of an embodiment of a document 100 according to the present invention, corresponding to the embodiment according to FIG.

The program instructions 108 in the embodiments contemplated herein include a program module 176 for performing coordinate transformations. The XY-coordinate of the position signal 168 is converted to the X'-, Y'-coordinates of the coordinate system 176 by the execution of the program module 176 and is further processed by the program command 108, The cursor is positioned correspondingly.

The program instructions 108 are also designed for the processing of the switching signal 178 which is emitted here by the operating element 174, in particular by the user.

In the embodiment contemplated herein, the document 100 does not have its own energy supply, particularly a primary battery. The energy supply is provided by an external reader 182 that utilizes the interface 180 'via the interface 180 of the document 100. For example, the interfaces 180 and 180 'may be interfaces according to RFID- or NFC-standards. In this case, the connection of the energy in the document 100 is performed in an inductive manner.

For example, the circuit 104 is formed as an RFID-chip. In this case, the interface 180 has an antenna that is used not only for energy supply but also for communication with the reader 182.

The electronic circuit 104, display element 102, touch pad-sensor 156 and / or interface 180 with various circuit components may be implemented as separate elements that operate electrically, e.g., as separate components, May be implemented as a single integrated circuit, in whole or in part.

5 shows a principle circuit diagram of one embodiment of a display device 102 as a so-called active matrix display. In this embodiment, the display element 102 comprises a matrix formed by rows and columns. At each intersection of each row line and column line, there is a predetermined display element 186, i.e., an activation circuit 184 for a so-called pixel. Figure 5 shows a detailed view of one embodiment of this activation circuit 184. When the column line has a logic "1" voltage level as well as the row line connected to the activation circuit 184 in the matrix, the SELECT transistor of the activation circuit 184 is connected so that the voltage applied to the data line 186, whereby the display element is controlled.

6 illustrates one embodiment of the touch pad-sensor 156, wherein the surface capacitive principle is applied. The touchpad-sensor 156 is coupled to a control and evaluation unit, or touch-controller 188, which provides a position signal 168. The touch-controller 188 may be an integral part of the touchpad-sensor 156 that forms an integral part of the electronic circuit 104 or is formed as a separate, separate part. The same is true for the touch-controller according to FIG. 7, wherein the touchpad-sensor 156 operates in accordance with the principle of projection capacitive sensors.

Figure 7 illustrates one embodiment of a touchpad-sensor 156 as an active matrix capacitive sensor. In this embodiment, the touch pad-sensor 156 includes row and column lines, and a sensor circuit 190 is provided at each intersection of the row line and the column line to supply a sensor signal for the corresponding scan point.

Fig. 8 shows one embodiment of this sensor circuit 190. Fig. Where the rows can be read simultaneously. In each case, two row lines A and B are connected to the sensor circuit 190. The functional method consists of three steps. First, the RESET-transistor is activated by the row line (A) and the capacitance C _pix is loaded. Then, the RESET-transistor is deactivated and the READ-transistor is turned off by the row line (B). Now the capacitance C _pix is changed by touch. In the last step, the READ-transistor is activated by the row line B, the capacitance value C _pix according to the touch is sensed by the amplification transistor AMP and transferred to the touch-controller 188 by the column line "sense line & As a result, the touch-controller emits position signal 168 (see embodiment according to Figs. 6 and 7).

Figure 9 illustrates another embodiment of a document 100 according to the present invention. The image sequence stored in the memory 110 includes at least one first image data set B1 for reproduction of a first image of the owner of the document 100, e.g., a front face image. In addition, the image sequence comprises at least one second image data set B2 for reproduction of a second image of the owner, e.g. a side face image.

For example, energy is coupled to the document 100 by the antenna 112, and execution of the program command 108 is automatically initiated. The program instructions 108 then control the driver 106 so that the image data sets B1 and B2 are reproduced in this order by the display element 102 in turn. For example, the reproduction of each image of the sequence of images for a predetermined period of time is performed, for example, 0.5 to 2 seconds before being converted to the next image of the image sequence. The reproduction of the image sequence can be repeatedly executed as long as the antenna 112 is supplied with energy. The playback duration of each image in the image sequence may be fixed or selected by the user interface, i. E. The touch pad or operating element 174. [

The image sequence may include other images than the front and side face images. For example, the owner's face is photographed on a number of different sides, and the camera angle changes from one view to the next. A sequential image data set obtained therefrom may appear on the display element 102 as a film sequence. Since the camera angle of the image data set is changed to the next, fast authentication of the document 100 with high recognition probability is possible.

In addition to the already known knowledge of individuals or individuals, the image data set may include biological characteristics such as, for example, an individual fingerprint or an entire fingerprint of an owner, an iris image or an owner's signature. In addition, the sequence stored in the electronic memory 110 may include one or more information that can be visually detected as clear text and / or information that can only be detected mechanically.

For example, it may include, for example, the name, address and date of birth of the document 100, visa information, transaction and status information, clear text information such as a single passport, and / or bar code, An image signal of a spectral region, a repetition period that can not be recognized by the human eye, an integrated digital watermark, or the like.

The document 100 may have an energy storage device 114 connected between the antenna 112 and the circuit 104. [ The energy storage device 114 may be, for example, a capacitor or a rechargeable battery.

During operation of the hardware operating element 174, power is connected to initiate playback of the image sequence including the images Bl through Bn. The re-operation of the operating element 174 may interrupt the supply of energy and hence the reproduction of the image sequence.

When the display element 102 is formed as a bistable display element, it is only after the reception of the interruption signal by the operating element 174 that a predetermined image of an image sequence such as, for example, the image B1 is reproduced on the display element The energy supply is interrupted. This has the advantage that this image (B1) can still be seen in the display element even when the energy supply is interrupted.

The document 100 may include a graphical user interface 120 having one or more manipulation elements, particularly icons. The user interface 120 may comprise, for example, an operating element 174 having a zoom function. By operating the operating element 174 on the touchpad, the user of the document can magnify the image reproduced on the current display element.

To this end, the program command 108 has a corresponding program command 126 for realizing the zoom function. Particularly, it is advantageous to manufacture the touchpad as a multi-touch touchpad, for example, because it is also possible to input the gesture of the user in a particularly convenient way to activate the zoom function.

Alternatively or additionally, at least one of the image data sets of the image sequence may comprise an enlarged detail of one of the other images of the image sequence.

The user interface 120 may also include virtual manipulation elements 128 and 130 for navigation of the user in the image sequence. By operating the operating elements 128 and 130 repeatedly, the user can select an image within the image sequence and cause the selected image to be played on the display element 102.

For example, a drive mode is selected in which the reproduction of the image sequence is repeatedly executed by activating the hardware operating element 174 for the energy supply connection, and each image of the image sequence is stored, for example, at 0.5 ≪ / RTI > for a predetermined time of ~ 2 seconds. On the contrary, when the virtual operating element 124, 128 or 130 is activated, the repetitive playback mode of this image sequence is stopped. When an image reproduced on the current display element is selected when the user operates the operation element 174 newly to return to the repeated reproduction mode or another image of the image sequence is aimed at by the operation of the operation elements 128 and 130 , It is maintained there.

According to one embodiment of the present invention, a cursor that can be brought to the selected display position by the user activating the touch pad to select one of the icons and icons shown in Fig. 9 representing the virtual operating elements 128 and 130 102 are also displayed on the display element 102. [ After the user selects one of the icons with the cursor, this selection can be confirmed by the operation of the operating element 174, thereby causing a function represented by the corresponding icon.

Navigation along the image sequence may also be performed such that each position on the touchpad is assigned to a particular image in the image sequence in the X-direction of the coordinate system 162. [ In order to select one of the images for display on the display element 102, the user may bring his finger to a predetermined X-position of the touchpad so that an image of the image sequence assigned to this X-position is displayed. Thereafter, when the user moves his or her finger 160 to the left or right along the X-axis, an image of the image sequence corresponding to the different X-position is displayed.
