Description

Light Engraving Electronic Card

The present disclosure relates to a light-engraving electronic card.

Electronic cards can be used for bank cards, credit cards, stored-value cards, or membership cards, etc. They can be divided into contact and contactless types according to the way they are used. Contact electronic cards must be physically in contact with external devices, while contactless electronic cards sense external devices. Regardless of the type of electronic card, there is a demand for further visual effects, appearance, or aesthetics.

The disclosed embodiment provides a light-engraving electronic card, which includes: a card body including at least one light-emitting area; a circuit module disposed in the card body and including a circuit carrier; at least one light-emitting element disposed in the card body and coupled to the circuit carrier; and a light guide plate disposed in the card body and including at least one light guide plate body pattern. The light guide plate body pattern is aligned with the light-emitting area, and the light guide plate guides the light emitted by the light-emitting element to the light-emitting area through the light guide plate body pattern, so that the light-emitting area emits light.

In some embodiments, the pattern of the light guide plate body includes an engraved mark pattern or a plurality of air bubbles. The pattern of the light guide plate body is a pattern presented by the light guide plate through its body itself, that is, a pattern presented by the light guide plate without adding additional physical elements to the light guide plate. The engraved mark pattern is located on the surface of the light guide plate and includes at least one groove, wherein the groove is covered with a horizontal film to form a cavity between the groove and the horizontal film. A plurality of air bubbles are located inside the light guide plate. The card body includes a first plate and a second plate, wherein the light emitting area is located on the first plate, and the circuit module, the light emitting element and the light guide plate are located between the first plate and the second plate. The card body includes another light emitting area, which is located on the second plate and aligned with the light emitting area on the first plate. One of the ink layers and the light emitting area is located on two sides of the light guide plate, respectively. The ink layer is aligned with the main pattern of the light guide plate, and the ink layer includes luminous ink or photosensitive ink. The light emitting area is an opening or a light-transmitting material. The material of the card body includes plastic, metal, or a combination thereof. The material of the light guide plate includes PVC, PET, PC or PMMA. The light guide plate has at least one perforation to accommodate a light-emitting element. The light-emitting element is a side-emitting diode and emits light toward the main pattern of the light guide plate. The number of the at least one light-emitting element is four. The light guide plate has at least four perforations to accommodate four light-emitting elements respectively. The four light-emitting elements are side-emitting diodes and are arranged along the edge of the main pattern of the light guide plate. The circuit module includes a contactless RF antenna and/or a contactable access chip. The contactless RF antenna is arranged on the circuit carrier, and/or the contactable access chip is arranged on the circuit carrier. The first plate and the second plate respectively include a first shading portion and a second shading portion. The first shading portion does not shield the light emitting area. The circuit module, the light-emitting element and the light guide plate are arranged between the first shading portion and the second shading portion.

As described above, since the light guide plate is directly provided with a visible light guide plate body pattern (such as a carving mark pattern or a bubble area), the light emitted by the light-emitting element under extremely limited power is guided by the light guide plate to directly present a pattern or bubble-like visual effect on the light guide plate, such as the carving mark pattern or the bubble area, and is visible to the outside through the light-emitting area so that the user or other persons can see it, thereby more efficiently utilizing light energy to present visual effects, and the electronic card can present a pattern or bubble-like visual effect without adding a pattern element on or outside the light guide plate. When the electronic card is accessing data or exchanging transaction data, it also has the function of providing a prompt.

The following disclosure provides many different embodiments, or examples, for implementing different features of the provided subject matter. To simplify the disclosure, specific examples of components and configurations are described below. Of course, these components and configurations are only examples and are not intended to be limiting.

Electronic cards can be used for bank cards, credit cards, debit cards, stored-value cards, ticket cards, membership cards, commemorative cards, IC cards, ID cards, etc. Electronic cards are usually designed to be easy to carry, take and hold, so their size is not too large. For this reason, electronic cards usually do not have batteries but need to be powered by external devices. Electronic cards can be divided into contact type and contactless type according to the power supply method. The contact type is that the chip is exposed on the surface of the card so as to make electrical contact with external devices such as card readers, and can be used as a contact electronic card. For example, after the electronic card is inserted into the card reader, the card reader contacts the chip of the electronic card to access (read/write/update) data in the chip of the electronic card; the contactless type is that a radio frequency antenna (or induction coil) is embedded in the card to sense the external device. , can be used as a contactless electronic card. For example, when the electronic card is close to an external device, the RF antenna of the electronic card is wirelessly coupled with the external device. The external device supplies power to the electronic card through wireless coupling and can access the RF identification tag of the electronic card or access the data on the chip of the electronic card through RF communication. The wireless coupling is, for example, mutual inductive coupling, the RF identification tag is, for example, passive or semi-passive, and the RF communication is, for example, near field communication (NFC). The electronic card can also be a hybrid, which has a chip for contact use and an RF antenna for contactless use. It can be used as a contact or contactless electronic card depending on the actual situation, and the function of the RF communication chip can also be integrated into the chip for contact use.

In some embodiments, the external device can provide power to the electronic card to emit light. In some embodiments, the external device can provide power to the electronic card to access data in the chip of the electronic card. In some embodiments, the external device can provide power to the electronic card to access data in the chip of the electronic card and make the electronic card emit light at the same time.

Regarding the size of electronic cards, for applications such as bank cards, credit cards, or debit cards, the size is usually regulated by ISO 7810, ISO 7816, and ISO/IEC 14443, which are generally 85.60 mm long, 53.98 mm wide, and 0.76 mm thick. For other applications, the size of electronic cards varies depending on the region. For example, in Taiwan, the general card size is 90 mm X 54 mm; in countries such as the United Kingdom, France, and Germany, the general card size is 85 mm X 55 mm; in Canada and the United States, the general card size is 3.5 X 2 inches, approximately 88.9 mm X 50.8 mm. Even if the size varies depending on the region, application, or designer's decision, electronic cards can usually be put into a wallet, purse, or pocket, and their thickness is usually no more than 1 mm, generally about or less than 0.8 mm.

FIG. 1 and FIG. 2 are three-dimensional schematic diagrams of a light-engraving electronic card 1 according to an embodiment, and FIG. 3 is an exploded schematic diagram of a light-engraving electronic card 1 according to an embodiment such as FIG. 1. A light-engraving electronic card 1 includes a card body 2, and includes a circuit module 3, at least one light-emitting element 4, and a light guide plate 5 disposed in the card body 2. The circuit module 3 includes a circuit carrier 31, and the light-emitting element 4 is coupled to the circuit carrier 31. The card body 2 includes a light emitting area 20, which is visible to the outside. The light guide plate 5 includes a light guide plate body pattern 50, which may include an engraved pattern 51 (as shown in FIG. 1) or a bubble area 52 (as shown in FIG. 2). The engraved pattern 51 or bubble area 52 of the light guide plate body pattern 50 is aligned with the light emitting area 20 and is therefore also visible to the outside. The light guide plate 5 guides the light emitted by the light emitting element 4 through the engraved pattern 51 or bubble area 52 of the light guide plate body pattern 50 to the light emitting area 20, so that the light emitting area 20 emits light with varying brightness refracted and/or reflected by multiple interfaces in the engraved pattern 51 or bubble area 52.

The light guide plate body pattern 50 is a pattern presented by the light guide plate 5 itself, that is, a pattern presented by the light guide plate 5 without adding any additional physical elements to the light guide plate 5. For example, the engraving pattern 51 is a pattern presented by engravings on the surface of the light guide plate 5, and the bubble area 52 is a bubble pattern presented by a plurality of bubbles inside the light guide plate 5. In addition, the engravings on the surface of the light guide plate 5 and the bubbles inside the light guide plate 5 also help guide light from the light guide plate 5 to the light exit area 20.

Since the power of electronic cards is limited, it is not easy to increase the visual effect of electronic cards by increasing the power. This is because the thickness of the standard electronic card body is only about 0.8mm, which means that the light-emitting element inside the card must be very small. For general contactless electronic cards, the power for light emission is actually converted from weak radio waves from external devices through radio frequency antennas.

Since the light guide plate 5 is directly provided with an externally visible light guide plate body pattern (such as a carved pattern 51 or a bubble area 52), the light emitted by the light-emitting element 4 under extremely limited power is guided by the light guide plate 5 to directly present a pattern or bubble-like visual effect on the carved pattern 51 or the bubble area 52 of the light guide plate body pattern on the light guide plate 5, and is visible to the outside through the light emitting area 20 so that the user or other persons can see it. Therefore, light energy can be used more efficiently to present visual effects, and the electronic card can present a pattern or bubble-like visual effect without adding a pattern element on or outside the light guide plate. When the electronic card is accessing data or exchanging transaction data, it also has the function of providing a prompt.

The card body 2 includes a first plate 21 and a second plate 22, wherein the light exit area 20 is located on the first plate 21, and the circuit module 3, the light emitting element 4 and the light guide plate 5 are located between the first plate 21 and the second plate 22. In some embodiments, the light exit area 20 is an opening of the first plate 21, and the opening is not filled with material or can be filled with a light-transmitting material or covered with a light-transmitting material, so that the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50 is exposed to the first plate 21 and visible. In another embodiment, the light exit area 20 is a light-transmitting material covering the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50, so that the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50 can still be visible through the light exit area 20 on the first plate 21.

The material of the card body 2 includes plastic, metal, or a combination thereof. The plastic material may include ABS, PETG, PVC or PET, etc. The plastic material may be or include a light-transmitting material or an opaque material; the metal material may be or include iron, aluminum, magnesium, copper, silver, gold, alloy, or a combination thereof, etc. The metal material may be an opaque material. The first plate 21 may be made of plastic, metal, or a combination thereof, and the second plate 22 may be made of plastic, metal, or a combination thereof. The first plate 21 and the second plate 22 may be made of the same material, such as plastic material or metal material; the first plate 21 and the second plate 22 may be made of different materials, such as one is a plastic material and the other is a metal material.

The material of the light guide plate 5 includes PVC, PET, PC, or PMMA, etc. The light guide plate 5 has at least one through hole 53 to accommodate the light emitting element 4. The light emitting element 4 is a side-emitting diode and emits light toward the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50. The light guide plate 5 can be a thin plate or a film, and its thickness is, for example, less than 0.4 mm, less than 0.2 mm, or less than 0.1 mm.

In some embodiments, the first plate 21 and the second plate 22 may be made of metal, and the light exit area 20 is an opening of the first plate 21. In some embodiments, the first plate 21 and the second plate 22 may be made of plastic, and the light exit area 20 is a light-transmitting material of the first plate 21, and the other parts of the first plate 21 and the second plate 22 may be or include opaque materials.

In some embodiments, the first plate 21 and the second plate 22 may include a first light shielding portion 211 and a second light shielding portion 221, respectively. The first light shielding portion 211 does not shield the light emitting area 20, and the circuit module 3, the light emitting element 4 and the light guide plate 5 are arranged between the first light shielding portion 211 and the second light shielding portion 221. The first light shielding portion 211 and the second light shielding portion 221 can provide light shielding, which can be light shielding ink, or can be the surface of the metal material of the first plate 21 and the second plate 22, so that the light guide plate 5 can guide the light emitted by the light emitting element 4 to the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50 through the first light shielding portion 211 and the second light shielding portion 221.

In addition, the first light shielding portion 211 and the second light shielding portion 221 can be a full-surface opaque shielding layer, but the first light shielding portion 211 is not disposed on the light emitting area 20 so that the light emitting area 20 is still not shielded by the first light shielding portion 211. In addition, the surfaces of the first light shielding portion 211 and the second light shielding portion 221 can be superimposed with desired patterns so that the electronic card 1 can better meet actual needs.

The circuit module 3 includes a contactless RF antenna 32 and/or a contactable access chip 33. The electronic card may be a hybrid, wherein the contactless RF antenna 32 is disposed on a circuit board 31, and the contactable access chip 33 is disposed on the circuit board 31. The circuit board 31 may be made of a light-transmitting material or a light-impermeable material. In some embodiments, if the electronic card is contactless, it may not have the contactable access chip 33, but there is still a chip in the card disposed on the circuit board 31 and coupled to the contactless RF antenna 32. In some embodiments, if the electronic card is contactless, it may not have the contactless RF antenna 32. When a contact-accessible chip 33 is provided, the first plate 21 and the light guide plate 5 may have openings 212 and 57 aligned with the contact-accessible chip 33 so that the contact-accessible chip 33 is exposed and disposed on the card body 2 .

The number of the light-emitting elements 4 is, for example, four, and the light guide plate 5 includes at least the same number of through holes 53 as the light-emitting elements 4, for example, at least four through holes 53 to respectively accommodate four light-emitting elements 4. The four light-emitting elements 4 are side-emitting diodes that can emit light toward the light guide plate main body pattern 50, and are arranged in a rectangular shape and disposed near the light guide plate main body pattern 50.

In some embodiments, the card body 2 includes a frame 24 to accommodate the circuit module 3 and the light guide plate 5 in the frame 24. The frame 24 is sandwiched between the first plate 21 and the second plate 22. The frame 24 may be opaque or provided with a light shielding element to prevent the light emitted by the light-emitting element 4 from leaking out of the frame 24. In some embodiments, the edge of the first plate 21 or the second plate 22 may be formed with a frame, for example, all or part of the frame 24 may be an integrally formed part with the first plate 21, or all or part of the frame 24 may be an integrally formed part with the second plate 22. The first plate 21 and the second plate 22 are combined through the frame 24 to form a containing space in the card body 2 to set the circuit carrier 31 of the circuit module 3 and the light guide plate 5. In some embodiments, the card body 2 may not include the frame 24. In this case, the side of the light guide plate 5 can be directly used as the side of the electronic card 1, and the side of the light guide plate 5 can be designed to be opaque or provided with a shading element to prevent the light emitted by the light-emitting element 4 from leaking out from the side. The side of the circuit carrier 31 can also be directly used as the side of the electronic card 1, and the side of the circuit carrier 31 can be designed to be opaque or provided with a shading element to prevent the light emitted by the light-emitting element 4 from leaking out from the side. In some embodiments, the edge of the light guide plate 5 may be formed with a frame, for example, all or part of the frame may be an integral part with the light guide plate 5, and the circuit carrier 31 of the circuit module 3 is disposed in the frame of the light guide plate 5. The frame of the light guide plate 5 may extend downward to accommodate the outer side surface of the circuit carrier 31 on the inner side of the frame.

Although FIG3 is drawn based on the electronic card 1 of FIG1, the components and descriptions in FIG3 are also applicable to the electronic card 1 of FIG2. In addition, the electronic card of FIG1 to FIG3 can be a single-sided electronic card or a double-sided electronic card as shown in FIG4.

FIG4 is a three-dimensional schematic diagram of the light-engraved electronic card 1 according to the embodiment. The card body 2 may include another light-emitting area 23, which is located on the second plate 22 and aligned with the light-emitting area 20 on the first plate 21. The engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50 is also aligned with the light-emitting area 23, so it can also be visible to the outside through the light-emitting area 23. The light guide plate 5 guides the light emitted by the light-emitting element 4 through the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50 to the light-emitting area 20 and the light-emitting area 23, so that the light-emitting area 20 and the light-emitting area 23 emit light. The engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50 can present visual effects such as patterns or bubbles on both sides of the electronic card 1.

In some embodiments, the electronic card with single-sided light output allows the contact access chip 33 and the light output area 20 to be arranged on the same side of the electronic card 1. In some embodiments, the electronic card with single-sided light output allows the contact access chip 33 and the light output area 20 to be arranged on both sides of the electronic card 1.

Figures 5A to 5C are cross-sectional schematic diagrams of the light-engraved electronic card according to the embodiment. In Figures 5A and 5B, the engraved pattern 51 is located on the surface of the light guide plate 5 and includes at least one groove 511. In some embodiments, the groove 511 is V-shaped or U-shaped, and the opening of the groove 511 faces the light exit area 20. The groove 511 is covered with a horizontal film 54 to form a cavity 55 between the groove 511 and the horizontal film 54. Air can be left in the cavity 55. The light emitted by the light-emitting element 4 can be refracted through the groove 511 in the light guide plate 5 and then emitted to the cavity 55 to the light exit area 20. The horizontal film 54 can cover the entire surface of the light guide plate 5, or only cover the engraved pattern 51.

The groove 511 is a carved mark on the surface of the light guide plate 5 to present a carved mark pattern 51. The groove 511 can be made by laser engraving, knife engraving, or molding. The carved mark pattern 51 is usually composed of a plurality of line segments. For example, these line segments are the outline of the pattern, or the texture line, or the representation line, etc. The groove 511 is formed on the surface of the light guide plate 5 according to these line segments.

The horizontal film 54 can be attached to the engraved pattern 51, for example, by gluing or fastening. The horizontal film 54 and the cavity 55 are provided to prevent the first plate 21 of the card body 2 from sinking into the groove 511 during the manufacturing process. The presence of the cavity 55 allows the groove 511 to emit light more efficiently to the light exit area 20. The groove 511 and the cavity 55 help guide the light from the light guide plate 5 to the light exit area 20. Generally speaking, in the process of manufacturing electronic cards, it is usually not desirable to generate engraved marks or cavities in or on the card body 2 or the light guide plate 5, because engraved marks or cavities are considered to be process defects, and electronic cards with engraved marks or cavities are usually considered to be defective. However, in the present disclosure, the engraved marks or cavities considered to be defects are used to present the pattern and its visual effect by using their optical properties.

In some embodiments, for example, FIG. 5A is an electronic card with single-sided light output, and FIG. 5B is an electronic card with double-sided light output. In FIG. 5B, the light output area 20 and the light output area 23 are located on two sides of the light guide plate 5, and the engraved pattern 51 and its groove 511 and the cavity 55 are located and aligned between the light output area 20 and the light output area 23. In addition, another groove, a horizontal film and another cavity (not shown) may be provided on the other side of the light guide plate 5 (for example, the lower surface in the figure), and the pattern presented by the other groove may correspond to the pattern presented by the groove 511, for example, symmetrical with respect to the light guide plate 5.

In FIG. 5C , the bubble area 52 includes a plurality of bubbles inside the light guide plate 5. The bubbles can be generated randomly or intentionally. The bubbles can also be arranged randomly or intentionally into a specified pattern. The bubbles also help guide the light from the light guide plate 5 to the light exit area 20. Generally speaking, in the process of manufacturing electronic cards, it is usually undesirable to generate bubbles in the card body 2 or the light guide plate 5, because bubbles are considered to be process defects, and electronic cards with bubbles are usually considered to be defective. However, in the present disclosure, the bubbles that are considered to be defects are used to present visual effects by using their optical properties.

In some embodiments, for example, FIG. 5C is an electronic card with single-sided light output. If the electronic card in FIG. 5C is changed to an electronic card with double-sided light output, the light output area 20 and the light output area 23 can be located on two sides of the light guide plate 5 as shown in FIG. 5B, and the bubble area 52 is located and aligned between the light output area 20 and the light output area 23.

In addition, in FIG. 5A and FIG. 5C , an ink layer 56 is provided on the light guide plate 5. The ink layer 56 and the light exit area 20 are respectively located on two sides of the light guide plate 5. The ink layer 56 is aligned with the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50. The ink layer 56 includes luminous ink or photosensitive ink. The shielding of the first light shielding portion 211 and the second light shielding portion 221 can enhance the effect of guiding the light emitted by the light emitting element 4 in the light guide plate 5. The ink layer 56 can also increase the amount of light reflected to the light exit area 20 and the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern 50, thereby enhancing the light output and visual effect. In addition, in some embodiments, the ink layer 56 may not be provided on the light guide plate 5.

6 is a schematic diagram of the configuration of the light-emitting elements of the optically engraved electronic card according to an embodiment. The number of the light-emitting elements 4 is, for example, four. The light guide plate includes at least the same number of perforations as the light-emitting elements 4, for example, at least four perforations to accommodate the four light-emitting elements respectively. The four light-emitting elements are side-emitting diodes and are configured along the edge of the light guide plate main body pattern 50.

In addition, in some embodiments, the card body of the electronic card may include a plurality of light emitting areas on the same side of the electronic card, such as the upper surface of the electronic card in the above figure. In some embodiments, the card body of the electronic card may include a plurality of light emitting areas on different sides of the electronic card, such as the upper surface and the lower surface of the electronic card in the above figure. The light guide plate of the electronic card may include a plurality of light guide plate body patterns, and these light guide plate body patterns are respectively aligned with the plurality of light emitting areas. These light guide plate body patterns may all be engraving patterns; or these light guide plate body patterns may all be bubble areas, and the bubble areas include a plurality of bubbles located inside the light guide plate; or one of these light guide plate body patterns is an engraving pattern, and the other is a bubble area, and the bubble area includes a plurality of bubbles located inside the light guide plate.

In addition, in some embodiments, the edge of the card body, light guide plate or circuit carrier of the electronic card may be designed to be opaque or provided with a light shielding element to prevent the light emitted by the light emitting element from leaking out from the edge of the electronic card.

In addition, in some embodiments, the edge of the card body, light guide plate or circuit board of the electronic card can be designed to be light-transmissive so that the light emitted by the light-emitting element can be emitted from the edge of the electronic card, thereby achieving another visual effect. For example, the engraved pattern 51 or the bubble area 52 of the light guide plate body pattern presents a pattern or bubble shape through illumination while the edge of the card also emits light to set off the engraved pattern 51 or the bubble area 52.

The above content summarizes the features of several embodiments or examples so that those with ordinary knowledge in the art can better understand the various aspects of the present disclosure. Those with ordinary knowledge in the art should recognize that they can easily use the present disclosure as a basis for designing or modifying other processes and structures to achieve the same purpose and/or achieve the same advantages of the embodiments or examples introduced herein.
