SUMMARY

[0003] The present application provides a card swiping device under a screen, a manufacturing method and an electronic device to solve the problem that the proportion of the screen of the existing card swiping host on the host panel is small, resulting in less information displayable by the screen.

[0005] In the present application, the through hole along the first direction is arranged on the shielding cover, and the transmitting and receiving ends of the card reading module are located in the through hole, thereby reducing the electromagnetic shielding effect of the shielding cover on the card reading module, so that the card reading module can transmit or receive signals through the through hole. Since the through hole is located in the projection range of the display screen in the first direction, the transmitting and receiving ends of the card reading module do not need to be exposed on the host panel, thereby improving the proportion of the screen on the host panel and improving the information displayable by the screen.

[0006] In combination with the technical solution of the above-mentioned first aspect, in some possible implementation manners, the card reading module comprises: an antenna board and a card reading mainboard, the antenna board is arranged in the through hole; the card reading mainboard is electrically connected with the antenna board, the card reading mainboard is used for processing the signals received by the antenna board and / or controlling the antenna board to transmit signals.

[0007] In the embodiment of the present application, the antenna board is arranged in the through hole, the electromagnetic shielding effect of the isolation cover on the antenna board is reduced, and the antenna board can transmit or receive signals through the through hole.

[0008] In combination with the technical scheme provided in the first aspect, in some possible implementation manners, the antenna board and the card reading main board are electrically connected through a wire with a specified length, and the specified length is any value in the range of 5cm-13cm.

[0009] In the embodiment of the present application, the card reading main board and the antenna board are connected through the wire, so that the antenna board and the card reading main board can be arranged at different positions, and the arrangement position of the antenna board is more flexible. Moreover, by setting the length of the wire in the range of 5cm-13cm, the influence of the wire on the card swiping distance can be reduced.

[0011] In the embodiment of the present application, the antenna board is attached to the display screen, so that when a user swipes a card, the signal received by the antenna board is stronger, and the success rate of card swiping is improved.

[0012] In combination with the technical scheme provided in the first aspect, in some possible implementation manners, when the vertical distance between the antenna board and the card reading main board is greater than or equal to a first preset threshold, the area of the antenna board overlapping the card reading main board is less than or equal to the area of the antenna board itself; when the vertical distance between the antenna board and the card reading main board is equal to a second preset threshold, the area of the antenna board overlapping the card reading main board is less than or equal to 80% of the area of the antenna board itself; and when the vertical distance between the antenna board and the card reading main board is equal to a third preset threshold, the area of the antenna board overlapping the card reading main board is less than or equal to 50% of the area of the antenna board itself.

[0013] In the embodiment of the present application, the card reading main board generates electromagnetic signals when running, which interferes with the signal receiving or transmitting of the antenna board. Therefore, according to the vertical distance between the antenna board and the card reading main board, the overlapping area of the antenna board and the card reading main board is set, so as to reduce the interference of the card reading main board on the antenna board and ensure the reliability of the under-screen card swiping device.

[0016] With the technical solution provided by the first aspect, in some possible implementation manners, the through hole is provided with an opening on one side, so that the side wall of the through hole is not a closed ring, so as to reduce the electromagnetic shielding effect of the isolation cover on the antenna plate.

[0017] In the embodiment of the present application, since the side wall of the through hole is not a closed ring, the electromagnetic shielding effect of the isolation cover on the antenna plate is further reduced.

[0018] With the technical solution provided by the first aspect, in some possible implementation manners, the diameter of the opening is greater than or equal to 0.5 cm.

[0039] The technical solutions of the present application will be described below in conjunction with the drawings.

[0040] Please refer to Figure 2 , Figure 2 A structure diagram of a card swiping device 20 under a screen is provided for an embodiment of the present application. The card swiping device 20 under the screen includes a display screen 210, a isolation cover 220, and a mainboard 230.

[0041] The display screen 210, the isolation cover 220, and the mainboard 230 are sequentially overlapped along the first direction. The isolation cover 220 is provided with a through hole 221 along the first direction, and the through hole 221 is located within the projection range of the display screen 210 in the first direction. The mainboard 230 is provided with a card reading module 231, and the transmitting and receiving ends of the card reading module 231 are located within the through hole 221 to transmit or receive signals through the through hole 221. The transmitting and receiving ends of the card reading module are not provided on the mainboard.

[0042] The first direction is a direction perpendicular to the planes on which the mainboard 230, the display screen 210, and the isolation cover 220 are located.

[0043] The display screen 210 can be any model of display screen 210, and different display screens 210 can be selected according to actual needs, and the specific model is not limited here.

[0044] The isolation cover 220 is used to isolate the mainboard and the display screen 210, and to provide protection for the display screen 210.

[0045] Optionally, the isolation cover 220 can be made of metal material.

[0046] The shape of the through hole 221 can be set according to actual needs, for example, it can be rectangular, triangular, circular, irregular image, etc., and the specific shape of the through hole 221 is not limited here.

[0047] In an implementation, the card reading module 231 comprises an antenna board 232 and a card reading main board 233. The antenna board 232 is arranged in the through hole 221 of the isolation cover 220. The card reading main board 233 is electrically connected with the antenna board 232, and the card reading main board 233 is configured to process signals received by the antenna board 232 and / or control signals emitted by the antenna board 232.

[0048] The specific model of the antenna board 232 can be selected according to actual needs, but it can be understood that the greater the outer diameter of the antenna board 232, the greater the card swiping distance of the under-screen card swiping device 20. For example, the antenna board 232 with an outer diameter of 3.5 cm x 5 cm or the antenna board 232 with an outer diameter of 10 cm x 10 cm can be selected. In the case of the same card reading main board 233, the card swiping distance of the under-screen card swiping device 20 using the antenna board 232 with an outer diameter of 10 cm x 10 cm is greater than that of the under-screen card swiping device 20 using the antenna board 232 with an outer diameter of 3.5 cm x 5 cm. The above examples are only for easy understanding and should not be regarded as a limitation on the present application. The specific size and model of the antenna board 232 are not limited herein.

[0049] Optionally, the thickness of the antenna board 232 can be 1 mm, the copper box thickness of the antenna board 232 can be 18 um, the coil wire width of the antenna board 232 can be 1 mm, the spacing between the two coils can be 0.25 mm, and the total number of coils can be 4 turns.

[0050] In order to facilitate understanding of the two coils on the antenna board 232, please refer to Figure 3 As shown in Figure 3 The first coil TX1 of the antenna board 232 is wound inward from the outer coil, the second coil TX2 of the antenna board 232 is wound outward from the inner coil, and finally GND is connected from the middle position of the two coils, i.e. grounded.

[0051] The specific model of the card reading main board 233 can be selected according to actual needs. It should be noted that the higher the integrity of the card reading main board 233, the better the suppression of high-order harmonics of the card reading main board 233, and the smaller the radiation influence of the card reading main board 233 on the antenna board 232. The specific model of the card reading main board 233 is not limited herein. The integrity of the card reading main board 233 refers to the completeness of the shape of the card reading main board 233. The less the irregular shapes such as notches, corners, and hollows, the higher the integrity. Alternatively, the integrity of the card reading main board 233 also refers to the integrity of the functions of the card reading main board 233. For example, the card reading main board 233 is provided with a buzzer (for sound prompt when swiping card), a battery (for power storage function - for the buzzer), a card reading trigger function, a chip, and the more comprehensive the functions realized, the higher the integrity. It can also refer to the integrity of the circuit on the capacitor, resistor, and crystal oscillator.

[0052] The read card main board 233 can be arranged in a grid shape, that is, the copper layer of the read card main board 233 is in a grid shape.

[0053] To make the setting position of the antenna board 232 more flexible, in an embodiment, the antenna board 232 and the read card main board 233 are electrically connected by a wire of a specified length.

[0054] Since the wire can be bent, the antenna board 232 and the read card main board 233 can be arranged at different positions, for example, the antenna board 232 is arranged in the through hole 221, and the read card main board 233 is arranged on the main board 230.

[0055] The wire can be a wire of any type and material, for example, a 28-gauge tinned flexible wire. The example is only for easy understanding and should not be regarded as a limitation to the present application.

[0056] It should be noted that the length of the wire affects the card swiping distance of the under-screen card swiping device 20. The longer the wire, the closer the card swiping distance. Therefore, the length of the wire can be set to be within a range of 5 cm to 13 cm, that is, any value within the range of 5 cm to 13 cm. Within the range, the wire has less effect on the card swiping distance.

[0057] Optionally, to prevent the wire from affecting the card swiping distance of the under-screen card swiping device 20, after the wire is used to connect the antenna board 232 and the read card main board 233, the wire cannot be attached to the surface of the antenna board 232.

[0058] In actual use, if the parameters of the antenna board 232 and the read card main board 233 have been adjusted, to ensure the reliability of the under-screen card swiping device 20, different wires, for example, wires of different lengths or different materials, cannot be used. If different wires are needed to connect the antenna board 232 and the read card main board 233, the parameters of the antenna board 232 and the read card main board 233 need to be adjusted again.

[0059] The parameters of the read card main board 233 include the numerical value settings of electronic components on the circuit of the read card main board 233, for example, resistance value, capacitance size, and impedance ratio. The parameters of the antenna board 232 include the assembly parameters of the antenna board 232, that is, the area of the position overlap of the antenna board 232 and the read card main board 233 in the vertical direction, the distance between the antenna board 232 and the periphery of the through hole 221, and the like.

[0060] In the use of the flat cable to connect the antenna board 232 and the card reading main board 233, if the antenna board 232 and the card reading main board 233 are arranged at different positions, and the vertical distance between the antenna board 232 and the card reading main board 233 is not 0, in order to prevent the electromagnetic signal generated by the card reading main board 233 from interfering with the receiving or transmitting signal of the antenna board 232, the overlapping area of the antenna board 232 and the card reading main board 233 can be set according to the vertical distance between the antenna board 232 and the card reading main board 233, so as to reduce the interference of the card reading main board 233 on the antenna board 232 and ensure the reliability of the operation of the under-screen card swiping device 20.

[0061] When the vertical distance between the antenna board 232 and the card reading main board 233 is greater than or equal to the first preset threshold value, the area of the antenna board 232 and the card reading main board 233 is less than or equal to the area of the antenna board 232 and the card reading main board 233.

[0062] The first preset threshold value can be 3±0.3cm, that is, when the vertical distance between the antenna board 232 and the card reading main board 233 is greater than or equal to 3cm, the antenna board 232 and the card reading main board 233 can be completely overlapped. For ease of understanding, please refer to Figure 4 .

[0063] When the vertical distance between the antenna board 232 and the card reading main board 233 is equal to the second preset threshold value, the area of the antenna board 232 and the card reading main board 233 is less than or equal to 80% of the area of the antenna board 232 and the card reading main board 233.

[0064] The second preset threshold value can be 2±0.3cm, that is, when the vertical distance between the antenna board 232 and the card reading main board 233 is within the range of 2±0.3cm, the overlapping area of the antenna board 232 and the card reading main board 233 needs to be less than 80% of the area of the antenna board 232 and the card reading main board 233. For ease of understanding, please refer to Figure 5 .

[0065] When the vertical distance between the antenna board 232 and the card reading main board 233 is equal to the third preset threshold value, the area of the antenna board 232 and the card reading main board 233 is less than or equal to 50% of the area of the antenna board 232 and the card reading main board 233.

[0066] The third preset threshold value can be 1±0.3cm, that is, when the vertical distance between the antenna board 232 and the card reading main board 233 is within the range of 1±0.3cm, the overlapping area of the antenna board 232 and the card reading main board 233 needs to be less than 50% of the area of the antenna board 232 and the card reading main board 233. For ease of understanding, please refer to Figure 6 .

[0067] It can be understood that the main board 230 will also generate electromagnetic signal interference with the antenna board 232 receiving or transmitting signals when in operation, and therefore the overlapping area of the antenna board 232 and the main board 230 can be set according to the vertical distance between the antenna board 232 and the main board 230 to reduce the interference of the main board 230 on the antenna board 232 and ensure the reliability of the operation of the under-screen card swiping device 20. The specific implementation manner of setting the overlapping area of the antenna board 232 and the main board 230 according to the vertical distance between the antenna board 232 and the main board 230 is consistent with the specific implementation manner of setting the overlapping area of the antenna board 232 and the card reading main board 233 according to the vertical distance between the antenna board 232 and the card reading main board 233 as recorded in the foregoing, and for brief description, no longer be described here.

[0068] In order to make the card swiping signal received by the antenna board 232 stronger and thus improve the success rate of card swiping, the antenna board 232 can be attached to the display screen 210, and correspondingly, the isolation cover 220 is also attached to the display screen 210. At this time, the antenna board 232 and the isolation cover 220 are in the same plane.

[0069] Since the antenna board 232 is attached to the display screen 210, the antenna board 232 is closer to the position where the user swipes the card, and therefore the antenna board 232 can receive a stronger card swiping signal.

[0070] It can be understood that the antenna board 232 and the isolation cover 220 can also not be in the same plane, and at this time, the antenna board 232 is suspended below the through hole 221.

[0071] In order to further reduce the electromagnetic shielding effect of the isolation cover 220 on the antenna board 232, in one embodiment, the distance between the edge of the antenna board 232 and the inner wall of the through hole 221 is greater than or equal to a preset distance.

[0072] The greater the preset distance, the weaker the electromagnetic shielding effect of the isolation cover 220 on the antenna board 232, for example, the preset distance can be set to 1 cm, and the shape of the through hole 221 is rectangular, at this time, the positional relationship between the antenna board 232 and the through hole 221 is as shown in Figure 7 .

[0073] In another embodiment, an opening 222 can be provided on one side of the through hole 221 to make the side wall of the through hole 221 not a closed ring to reduce the electromagnetic shielding effect of the isolation cover on the antenna board 232. For ease of understanding, please refer to Figure 8 .

[0074] It can be understood that the greater the distance between the openings 222, the weaker the electromagnetic shielding effect of the isolation cover 220 on the antenna board 232, and the specific value of the opening 222 is not limited here.

[0075] Optionally, the diameter of the opening 222 is greater than or equal to 0.5 cm, which can effectively reduce the electromagnetic shielding effect of the isolation cover 220 on the antenna plate 232.

[0076] It can be understood that, after the opening 222 is arranged on one side of the through hole 221, the distance between the edge of the antenna plate 232 and the inner wall of the through hole 221 is greater than or equal to a second preset distance, which further reduces the electromagnetic shielding effect of the isolation cover 220 on the antenna plate 232.

[0077] The greater the second preset distance is, the weaker the electromagnetic shielding effect of the isolation cover 220 on the antenna plate 232 is. For example, the preset distance can be 0.5 cm.

[0078] In order to protect the main board 230 and the display screen 210, the under-screen card swiping device 20 further comprises a shell, which completely wraps the main board 230 and the isolation cover 220, and an opening 222 is arranged at the display screen 210 to expose the display screen 210.

[0079] The shell can be made of plastic material.

[0080] In order to protect the display screen 210, a protection plate 240 can be arranged on one side of the display interface of the display screen 210. The protection plate 240 is made of transparent material, for example, glass, tempered glass, transparent resin, etc. The specific type is not limited here. For ease of understanding, please refer to Figure 9 .

[0081] Based on the same inventive concept, the application also provides a method for manufacturing an under-screen card swiping device, as shown in Figure 10 , the steps of protection will be described below. Figure 10 .
