Description

Technical Field

[0001] The present invention relates to an electronic carrier and a pre-laminated structure for a smart card comprising a lighting element powered by a high frequency (HF) antenna. The present invention also relates to a lighting device including a lighting element incorporated in a smart card. Background Art

[0002] OLEDs and other lighting devices in pre-laminated structures and smart cards typically require external rectifier components to be able to receive harvested energy from an HF antenna (eg, an antenna having a resonant frequency of approximately 13.56 MHz).

[0003] These solutions are generally based on the use of a PCB comprising one or more than one antenna and rectifier components, wherein the electronic components are usually produced by etching techniques.

[0004] When the pre-laminated structure with LED or OLED components and the smart card are used in a Dual Interface (DI) card, there are two possible configurations for collecting the HF antenna.

[0005] In a first configuration, a single antenna is provided in the pre-laminated structure and / or smart card and is used both to enable data transfer required for contactless payment and to harvest energy for the LED or OLED in the same contactless reader field.

[0006] In a second configuration, two antennas are provided in the pre-laminated structure and / or smart card, namely an EMV antenna for contactless payment and an energy harvesting antenna (EH) for powering the LED or OLED in the field of the contactless reader.

[0007] In both configurations, the dynamic data transfer required for contactless payment is not affected by the energy harvesting antennas that consume energy from the same reader field at the same time. Indeed, if the two powering processes interfere with each other, the EMVco payment will be interrupted and the payment transaction will fail. Therefore, it is clear that a very specific and complex system for payment antennas and harvesting antennas needs to be designed.

[0008] Both the single antenna configuration and the dual antenna configuration have many disadvantages.

[0009] The single antenna configuration implies the implementation of a very complex system which must manage the modulation of the HF antenna to enable dynamic data transfer for contactless payment and at the same time it must provide enough energy to light up the LED or OLED. In practice, no external battery should be used to provide additional power to the LED or OLED.

[0010] The dual antenna configuration requires lower electronic complexity than the single antenna configuration, but it requires at least four diodes and a capacitor to implement a full rectifier in order to connect the energy harvesting antenna and the LED or OLED. Therefore, the production cost is still high.

[0011] Furthermore, since each microcontroller for contactless payment requires its own specific payment antenna, and since the payment antennas may be made in different sizes, a large number of different PCBs must obviously be manufactured. These PCBs generally require large dimensions and do not conform to the size standards of DI cards.

[0012] Another challenge presents the need to integrate the PCB with connected LEDs or OLEDs into a multi-layer pre-laminated structure and then into the card body.

[0013] Given all the challenges described above (i.e., the large number of electronic components required, the large size of the PCB, and the difficulty of PCB integration), DI cards with LEDs or OLEDs are generally very expensive and cannot be mass-produced to meet market demand. Summary of the invention

[0014] Therefore, the object of the present invention is to provide an electronic carrier and a pre-laminated structure for an antenna to be integrated into a DI smart card, which overcomes one or more of the disadvantages exemplified above. Furthermore, the object of the present invention is to provide a lighting device including a lighting element to be integrated into a smart card, wherein the number of electronic components for energy harvesting is reduced to a minimum. Accordingly, the size of the PCB can be reduced so that it carries a single electronic component for energy harvesting. According to an alternative solution, a PCB for carrying electronic components for energy harvesting may not be required.

[0015] The electronic support, the pre-laminated structure and the lighting device according to the invention are as set out in the appended claims.

[0016] According to one aspect of the present invention, there is provided an electronic carrier for an antenna used in a smart card, which comprises the following components:

[0017] Antenna substrate;

[0018] a first wire antenna configured to provide energy to an illumination element of the smart card; and

[0019] a second wire antenna configured to provide energy to an electronic module used by the smart card for contactless data transfer;

[0020] Wherein, the first antenna and the second antenna are formed on opposite sides of the antenna substrate.

[0021] According to an embodiment of the present invention, there is provided an electronic carrier, wherein the first linear antenna does not provide energy to the electronic module, and the second linear antenna does not provide energy to the lighting element.

[0022] According to an embodiment of the present invention, there is provided an electronic carrier, wherein the first linear antenna is configured to provide energy only to the lighting element, and the second linear antenna is configured to provide energy only to the electronic module.

[0042] This specification is presented for illustrative purposes, but is not intended to be exhaustive or limited to the disclosed embodiments. The scope of protection of the present disclosure is defined in the appended claims. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope of the present disclosure. The embodiments are selected and described to best illustrate the principles and practical applications of the present disclosure, and to enable those of ordinary skill in the art to understand the various embodiments of the present disclosure and the various modifications suitable for the specific purposes contemplated. Finally, those areas that are considered to be known to those skilled in the art will not be described to avoid covering the described invention in a useless manner.

[0043] In the present disclosure, it should be understood that the terms "top", "bottom", "upper", "lower", "front", "back", "right", "left", etc. must be interpreted with reference to the accompanying drawings. However, it should be understood that in the context of the present disclosure, there is no preferred orientation of the electronic carrier, lighting device, pre-laminated structure and / or smart card according to the embodiments described below.

[0044] Hereinafter, the present invention will be described with reference to the accompanying drawings.

[0045] Figure 1 Schematically illustrated are three-dimensional views of the top side (on the left) and the bottom side (on the right) of an electronic carrier 100 according to an embodiment of the present invention, wherein the circumference of the EH antenna 104 for powering the lighting element is smaller than the circumference of the payment antenna 102. In other words, the EH antenna 104 and the payment antenna 102 are concentric with each other, and the size of the EH antenna 104 is smaller than the size of the payment antenna 102. The payment antenna 102 may be an EMV antenna.

[0046] The electronic carrier 100 includes a body 101 made of plastic such as PVC. The electronic carrier 100 includes a cutout portion 103 configured to accommodate a lighting device including a lighting element. For example, the cutout portion 103 may accommodate a reference Fig.9A , Fig. 9B , Figures 10 to 12 The lighting device 200 is described. The body 101 forms a substrate for the antenna.

[0047] The EH antenna 104 and the payment antenna 102 can be wire antennas, and they can be manufactured by wire embedding or air-core coil technology. The wire can be isolated or non-isolated, and it can be made of copper, aluminum and / or a metal alloy with low resistivity. The advantages of implementing the antenna by wire embedding technology are: more flexibility in antenna design and reduced production costs.

[0048] exist Figure 1 In one configuration, the EH antenna 104 and the payment antenna 102 are placed on opposite sides of the electronic carrier 100. In particular, the payment antenna 102 is placed on the top side of the electronic carrier 100, and the EH antenna 104 is placed on the bottom side of the electronic carrier 100. In another configuration (not shown), the EH antenna 104 and the payment antenna 102 may be at the same level on a single side of the electronic carrier 100. In another configuration (not shown), the EH antenna 104 and the payment antenna 102 may be formed on different sides of two different electronic carriers.

[0049] Preferably, the wire diameter of the payment antenna and the EH antenna is comprised in the range between 50 μm and 200 μm.

[0050] According to a preferred embodiment, the EH antenna and the payment antenna may be HF antennas. Preferably, the resonant frequency of the payment antenna is included in the range between 14 MHz and 18 MHz. Preferably, the resonant frequency of the EH antenna is included in the range between 13.56 MHz and 28 MHz.

[0051] Figure 2 Schematically illustrates the Figure 1 1 is a cross-section of an electronic carrier 100 of an embodiment of FIG. 1 , in which it can be seen that the circumference of the EH antenna 104 for powering the lighting element is smaller than the circumference of the payment antenna 102 .

[0052] Figure 3 Schematically illustrates a three-dimensional view of the top side (on the left) and the bottom side (on the right) of an electronic carrier 100 according to another embodiment of the present invention, wherein the perimeter of the EH antenna 104 is greater than the perimeter of the payment antenna 102. In other words, the EH antenna 104 and the payment antenna 102 are concentric with each other, and the size of the payment antenna 102 is smaller than the size of the EH antenna 104. Figure 4 The relationship between the sizes of the two antennas can also be seen in the cross-sectional view.

[0053] Figure 5 Schematically illustrated are three-dimensional views of the top side (on the left) and the bottom side (on the right) of an electronic carrier 100 according to another embodiment of the present invention, wherein the perimeter of the EH antenna 104 is equal to the perimeter of the payment antenna 102. In other words, the EH antenna 104 and the payment antenna 102 are concentric with each other and they have the same size. Figure 6 The relationship between the sizes of the two antennas can also be seen in the cross-sectional view.

[0054] Fig. 7A A top view of one side of an electronic carrier 100 according to another embodiment of the present invention is schematically illustrated, wherein the area of ​​the electronic carrier 100 is ideally divided into two parts. In other words, the area of ​​the electronic carrier 100 includes a first part A and a second part B, and in the first part A the first antenna or EH antenna 104 surrounds the second antenna or payment antenna 102, and in the second part B the second antenna 102 surrounds the first antenna 104, so that the first antenna 104 is cross-linked with the second antenna 102. The area of ​​the electronic carrier 100 is divided into two parts by an ideal line, and the first antenna 104 and the second antenna 102 are cross-linked corresponding to the ideal line.

[0055] exist Fig. 7AIn the illustrated configuration, the region of the electronic carrier 100 is ideally divided into two symmetrical parts, namely, a left part A and a right part B, relative to a vertical symmetry line C. However, this configuration is not restrictive, and the two parts A and B may be asymmetrical to each other and may have different sizes, such as different widths and / or different lengths. In addition, the two parts A and B may be defined relative to an ideal vertical line parallel to the symmetry line C and / or relative to an ideal horizontal line perpendicular to the symmetry line C.

[0056] In the left part A of the electronic carrier 100, the EH antenna 104 surrounds the payment antenna 102, and in the right part B of the electronic carrier 100, the payment antenna 102 surrounds the EH antenna 104, so that the payment antenna 102 is cross-linked with the EH antenna 104 corresponding to the symmetry line C and defines a cross-linking portion 105. In other words, the first width W1 of the EH antenna 104 in the left part A of the electronic carrier 100 is greater than the second width W2 of the payment antenna 102 in the left part A; in a similar manner, the first width W3 of the payment antenna 102 in the right part B of the electronic carrier 100 is greater than the second width W4 of the EH antenna 104 in the right part B. Preferably, the first width W1 of the EH antenna 104 is equal to the first width W3 of the payment antenna 102, and the second width W4 of the EH antenna 104 is equal to the second width W2 of the payment antenna 102. Corresponding to the cross-linking portion 105, the EH antenna 104 is bent to reduce the width from the first value W1 to the second value W4. In a similar manner, corresponding to the cross-linking portion 105, the payment antenna 102 is bent to increase the width from the second width value W2 to the first width value W3. Preferably, the bent portion of the EH antenna 104 forms a line parallel to the symmetry line C. Preferably, the bent portion of the payment antenna 102 forms a line perpendicular to the symmetry line C.

[0057] This configuration is advantageous because it ensures optimal performance of the payment antenna 102 during EMV payments. For example, EMVCo testing can result in a 100% pass rate.

[0058] even though Fig. 7A While the EH antenna 104 and the payment antenna 102 are shown formed at the same level on a single side of the electronic carrier 100, other configurations (not shown) are possible in which the EH antenna 104 and the payment antenna 102 are formed on opposite sides of the electronic carrier or on two different sheets that are subsequently coupled to form the electronic carrier.

[0059] Figure 7B An alternative configuration is schematically illustrated, in which the area of ​​the electronic carrier 100 is ideally divided into two symmetrical parts with respect to a horizontal symmetry line C', namely an upper part A' and a lower part B'.

[0060] In the upper portion A' of the electronic carrier 100, the EH antenna 104 surrounds the payment antenna 102, and in the lower portion B' of the electronic carrier 100, the payment antenna 102 surrounds the EH antenna 104, so that the payment antenna 102 and the EH antenna 104 are cross-linked corresponding to the symmetry line C' and define a cross-linked portion 105'. In other words, the first length D1 of the EH antenna 104 in the upper portion A' of the electronic carrier 100 is greater than the second length D2 of the payment antenna 102 in the upper portion A'; in a similar manner, the first length D3 of the payment antenna 102 in the lower portion B' of the electronic carrier 100 is greater than the second length D4 of the EH antenna 104 in the lower portion B'. Preferably, the first length D1 of the EH antenna 104 is equal to the first length D3 of the payment antenna 102, and the second length D4 of the EH antenna 104 is equal to the second length D2 of the payment antenna 102.

[0061] exist Figure 7B In the illustrated configuration, the area of ​​the electronic carrier 100 is ideally divided into two symmetrical parts, namely, an upper part A' and a lower part B', relative to a horizontal symmetry line C'. However, this configuration is not restrictive, and the two parts A' and B' may be asymmetrical to each other and may have different sizes, such as different widths and / or different lengths.

[0062] Figure 8 A preferred configuration of an electronic carrier 100 is schematically illustrated, wherein an energy harvesting (EH) antenna 104 surrounds a payment antenna 102, and the payment antenna 102 is formed of at least two partial coils 102A and 102B to improve signal quality and optimize EMV payments. In practice, a payment antenna comprising only one coil portion will have less interference, but poor signal quality, and may cause EMV payment failures.

[0063] The first coil 102A has a width H1 and a length L1. The second coil 102B has a width H2 and a length L2. Preferably, the width H1 of the first coil 102A is equal to the width H2 of the second coil 102B. The width H1 and the width H2 are smaller than the width H of the EH antenna 104 surrounding the two coils 102A and 102B of the payment antenna 102. Preferably, the length L1 of the first coil 102A is greater than the length L2 of the second coil 102B. The sum of the length L1 and the length L2 is smaller than the total length L of the EH antenna 104, so that the two coils 102A and 102B of the payment antenna 102 are surrounded by the EH antenna 104. In a similar manner, the width H1 of the coil 102A and the width H2 of the coil 102B are each smaller than the width of the EH antenna 104, so that the two coils 102A and 102B of the payment antenna 102 are surrounded by the EH antenna 104.

[0064] Fig.9A and Fig. 9BA three-dimensional view of a lighting device 200 including a lighting element 201 according to an embodiment of the present invention is schematically illustrated.

[0065] In the present disclosure, the lighting element 201 may indicate an Nth-degree nano-LED die, an LED array, an LED light guide element including at least one LED as a light source, and / or an organic LED (OLED). The lighting element 201 may, for example, be used to illuminate a predefined area of ​​a smart card, such as for illuminating a portion with a logo. Alternatively, the lighting element 201 may be used to indicate the working status of the smart card, such as for indicating a successful transaction.

[0066] According to a preferred embodiment of the present invention, the electronic assembly for collecting energy for the lighting element 201 may include a single diode 203 combined with an energy collection antenna. Fig.9A and 9B ), the electronic components for collecting energy for the lighting element 201 may include a diode 203 and a capacitor 204 in combination with an EH antenna. In this configuration, the diode is used to convert the AC voltage / current signal emitted from the EH antenna into a DC voltage / current signal, which can power a lighting element such as an OLED.

[0067] Preferably, the diode has a forward voltage lower than 350 mV at 3 V. Preferably, the diode has a forward current comprised in the range between 100 mA and 300 mA. Preferably, the diode has a reverse voltage comprised in the range between 10 V and 30 V. Preferably, the diode has a capacitance comprised in the range between 1 pF and 200 pF.

[0068] Preferably, the electronic components for collecting energy for the lighting element 201 are formed on a flexible printed circuit board (PCB) 210. Since the number of electronic components for collecting energy is reduced to a minimum number of one or two components according to the present invention, the size of the PCB 210 carrying these components can also be reduced. For example, if the number of energy collection components is reduced to one diode, the PCB 210 only needs to accommodate one diode, and its size can be reduced accordingly. For example, if the number of energy collection components is reduced to one diode and one capacitor, the PCB 210 needs to accommodate the diode and the capacitor, and its size can still be reduced relative to the prior art. In this way, the production process is cheaper.

[0069] The flexible PCB 210 may be made of epoxy glass tape, or polyimide, or similar materials. According to other examples, the flexible PCB may be made of a pure metal plate (e.g., copper), or of a flat or round wire attached to a plastic sheet. According to other examples, the PCB 210 may be made of the same material as the electronic carrier 100 (such as PVC, etc.).

[0070] Fig.9A and Fig.10 The connection between the lighting element 201 and the flexible PCB 210 carrying the energy harvesting components is schematically illustrated in FIG. The connection can be achieved by a conductive adhesive (ACF (anisotropic conductive film), ACP (anisotropic conductive paste), ICP (isotropic conductive paste)), by crimping or by simply pressing the rough surface of the electrode 212 on the PCB 210 into the electrode of the lighting device 200 during lamination.

[0071] Preferably, the connection between the flexible PCB 210 and the wires of the EH antenna 104 is made by micro-soldering (such as thermo-compression (TC) bonding, etc.), ICA (isotropic conductive adhesive), soldering, and / or press-fit connection.

[0072] The diode 203 and / or the capacitor 204 may be connected to the contact terminals of the lighting element 201 by using ACF, ACP, micro-soldering, micro-welding, ICA, or simply by press-fit contacts.

[0073] Fig.10 Schematically illustrates the Fig.9A A cross section of an embodiment of a lighting element 201 and its connection to a flexible PCB 210 including energy harvesting components 203 and 204.

[0074] According to an alternative advantageous embodiment of the present invention, the diode 203 may not be placed on the flexible PCB 210 that will be electrically connected to the lighting element 201, but the diode 203 may be connected to the lighting device 200 by a wire (e.g., a non-isolated wire). In this way, the production cost is further reduced and the assembly process is simplified. In fact, according to this configuration, there is no additional cost for forming a separate PCB to carry the diode 203 and / or the capacitor 204.

[0075] Fig.11 and Fig.12 An exemplary embodiment is shown in which the diode 203 is connected to the lighting element 201 by a wire.

[0076] Fig.11A top view of a lighting device 200 ′ is schematically illustrated, wherein the connection between the diode 203 and the terminals 210A and 210B of the lighting element 201 is made via a wire 220 having a meandering structure.

[0077] Fig.12 A top view of a lighting device 200" is schematically illustrated, wherein the connection between the diode 203 and the terminals 210A and 210B of the lighting element 201 is made via wires 220' having different meander structures. Fig.12 In the construction of Fig.11 The invention provides an improved (eg, lower resistance) and more reliable wire connection to the lighting element terminals.

[0078] Preferably, as in Fig.11 and 12 As can be seen in FIG. 2 , both ends of the wires 220 , 220 ′ (ie, the end in contact with the diode 203 and the end in contact with the terminals 210A and 210B of the lighting element 201 ) include a wire meander structure.

[0079] Advantageously, the electrical connections between the wires 220 , 220 ′ and the terminals 210A and 210B of the lighting element 201 may be made by micro soldering, ACF bonding, ACP bonding, isotropic adhesive and / or press fitting.

[0080] Preferably, the wires 220, 220' are positioned on the same layer forming the wire EH antenna.

[0081] Preferably, the diode 203 is placed on the same layer that forms the wires 220, 220' and the EH antenna.

[0082] Fig.13 A three-dimensional view of a card body 400 used in a smart card according to an embodiment of the present invention is schematically illustrated.

[0083] The card body 400 comprises a pre-laminated structure 300 including an electronic support for the antenna, and lighting means.

[0084] For example, the electronic carrier used for the antenna can be a reference Figures 1 to 8 Alternatively, the electronic carrier used for the antenna may have a structure such as FIG. 14A to FIG. 14C The structure shown.

[0085] For example, the lighting device may be as described above with reference to Fig.9A , Fig. 9B , Figures 10 to 12 The lighting device described.

[0086] It should be understood that any combination of the disclosed electronic carrier for the antenna (i.e., different antenna sizes and positions) and the disclosed lighting device (i.e., different configurations of the diode) can be included in the smart card according to the present invention. In the smart card according to the present invention, advantageously, the diode 203 and / or capacitor 204 for the lighting element 201, and the EH antenna 104 are manufactured on two different carriers (i.e., the lighting device 200 and the electronic carrier 100), respectively.

[0087] The electronic carrier 100 includes two linear antennas, namely the EH antenna 104 and the payment antenna 102. The electronic carrier 100 may include a single layer, or it may include multiple layers (such as Fig.13 100 and layer 120, etc.). In a multi-layer construction, the EH antenna 104 and the payment antenna 102 can be formed on two separate layers. For example, the two separate layers can be adjacent layers (ie, laminated to each other), or they can be separated by additional layers.

[0088] The electronic support 100 may be laminated to additional layers to form a pre-laminated structure (or pre-lam) 300. The pre-laminated structure 300 indicates a preliminary structure including multiple layers that are connected to each other by a thermal lamination process before the outer layers of the smart card are merged.

[0089] Fig.13 The card body 400 also includes a front layer 411 and a back layer 412, the front layer 411 including a translucent foil with printed elements, and the back layer 412 including a colored foil with printed elements, such as a white foil. In addition, the card body 400 includes a top cover layer and a bottom cover layer 410. A cavity is formed in the card body 400 to accommodate an ISO module 420 with an ID payment chip. For example, the cavity can be formed by milling. The ISO module 420 can be visible from the top cover layer 410. According to a preferred embodiment, the ISO module 420 can include energy collection components for the EH antenna, such as diodes and / or capacitors.

[0090] exist FIG. 14A to FIG. 14C , three different configurations for placing the EH antenna and the payment antenna are shown in cross-sectional view.

[0091] Fig.14A A cross-sectional view schematically illustrates a configuration of an electronic carrier 100 according to an embodiment of the present invention, in which an EH antenna 104 and a payment antenna 102 are formed on the same side of a body 101 of the electronic carrier 100 . Fig.14A The electronic support 100 includes a single layer.

[0092] Obviously, even though the EH antenna 104 is shown formed within the perimeter of the payment antenna 102, the opposite configuration is possible where the payment antenna 102 is formed within the perimeter of the EH antenna 104.

[0093] Fig. 14B A cross-sectional view schematically illustrates a configuration of an electronic carrier 100 according to another embodiment of the present invention, in which an EH antenna 104 and a payment antenna 102 are formed on different sides of a body 101 of the electronic carrier 100 . Fig. 14B The electronic support 100 includes a single layer.

[0094] Obviously, even if Fig. 14B The two antennas are shown as being of the same size, but configurations where the two antennas have different sizes are possible, for example, the circumference of the EH antenna 104 is smaller than the circumference of the payment antenna 102, or vice versa.

[0095] Fig. 14C A cross-sectional view schematically illustrates a configuration of an electronic carrier 100 according to another embodiment of the present invention, in which an EH antenna 104 and a payment antenna 102 are formed on different sides of a multi-layer electronic carrier. Fig. 14C The electronic carrier 100 comprises two layers 101, 101', and the payment antenna 102 and the EH antenna 104 are formed on the top sides of the layers 101 and 101', respectively. Alternatively, the payment antenna 102 and the EH antenna 104 can be formed on the bottom sides of the layers 101 and 101', respectively.
