[0040] The implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings.

[0041] It should be noted that the following is a description of the preferred embodiments of the present application, which does not constitute any limitation to the present application. The description of the preferred embodiments of the present application is only an explanation of the general principles of the present application. The embodiments described in this application are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", and technical features numbered with Arabic numerals 1, 2, 3, etc., and numbers such as "A" and "B", are only used for descriptive purposes and are only for the convenience of explanation, and do not represent a sequential relationship in time or space; they cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and numbered with Arabic numerals 1, 2, 3, etc. may explicitly or implicitly include one or more of the features. In the description of the present application, “several” means two or more than two, unless otherwise clearly and specifically defined.

[0043] In the prior art, there are also sheet cards with built-in chips, such as bank cards or ID cards with chips. Since they need to be light and easy to carry, the chips usually do not have batteries. For safety reasons, the information cannot be frequently modified. Instead, special equipment such as RFID near-field communication equipment is required to make and implant relevant information before use. It is impossible to change the relevant information in the card online in real time, and it is even more impossible to drive a display screen that requires real-time power consumption.

[0044] Since the electronic paper ink screen can still display content after power failure, it is a suitable choice for card display. In addition, the electronic paper ink screen can refresh the display content through the interface. When changing games, the card game content can be changed by changing the display content. It is a more economical and flexible card. How to achieve more convenient and quick content updates is something that needs to be considered. Conventional paper cards can be made very light and thin. If the weight is increased appropriately for the flexibility of the game, however, if the electronic cards used in the game are equipped with energy devices such as batteries, the weight will be increased too much, which will affect the grip and use. How to make electronic cards convenient and quick to update content while taking into account the comfort of use is a problem that needs to be considered.

[0045] like Figure 1 As shown, in an embodiment of an electronic card, the electronic card includes an electronic ink screen unit, a card control unit, a card communication unit, and a card power supply unit; the card power supply unit is electrically connected to the electronic ink screen unit, the card control unit, and the card communication unit to supply power to the electronic ink screen unit, the card control unit, and the card communication unit; the card power supply unit includes a power contact, which is connected to the external power supply by contacting an external device, and the card power supply unit transfers the external power supply to the electronic ink screen unit, the card control unit, and the card communication unit; the card control unit is electrically signal connected to the card communication unit; the card control unit is electrically signal connected to the electronic ink screen unit; the card control unit receives an external command through the card communication unit, and the card control unit changes the content displayed by the electronic ink screen unit according to the command.

[0046] The application scenarios of electronic cards are mostly game card scenarios, of course, they can also be other non-game types such as thin and small paper cards with changeable content such as electronic business cards. Its size is comparable to that of regular cards, such as the size of playing cards or bank cards. The electronic cards in these scenarios need to be relatively thin and light, and easy to grasp or hold. Therefore, the electronic ink screen unit, card control unit, card communication unit, and card power supply unit in the electronic card can be minimized functional units. The electronic ink screen unit can realize display; the card control unit can realize the control of the electronic ink screen unit; the card communication unit can complete communication with the outside, and the card power supply unit can obtain energy used to change the display content from the outside.

[0047] like Figure 2 and Figure 3As shown, in the embodiment of the electronic card, the card communication unit includes a card bus communication module, and the card communication unit communicates with the external device through a bus communication protocol. Different communication interfaces can be set in the card bus communication module, such as IIC communication interface, 485 communication interface, RS232 communication interface and other standard interfaces in the prior art. The communication protocol corresponds to the communication interface.

[0048] like Figure 3 and Figure 4 As shown, in the embodiment of the electronic card, an ID module is included, and the card bus communication module communicates according to the number inside the ID module.

[0049] like Figure 4 and Figure 6 As shown, in the embodiment of the electronic card, the card communication unit includes a card wireless communication module, and the card communication unit communicates with the external device through a wireless communication protocol. There are many wireless communication methods.

[0050] like Figure 4 As shown, in the embodiment of the electronic card, the card wireless communication module can be a Bluetooth communication module, which communicates with the outside through Bluetooth. The wireless communication protocol is the Bluetooth communication protocol. The electronic card can establish a communication connection with an external terminal such as a mobile phone through wireless communication, and the card control unit receives commands sent by the external mobile phone through the card communication unit.

[0051] like Figure 4 As shown, in the embodiment of the electronic card, the electronic card can establish a communication connection with an external card power supply device such as a card box through wireless communication, and the card control unit receives commands sent by the card box through the card communication unit.

[0052] like Figure 4 and Figure 3 As shown, in the embodiment of the electronic card, an ID module is included, and the wireless communication module communicates according to the number inside the ID module. The ID module sets an identification number for each card. When the content of multiple cards is refreshed, the corresponding change content can be determined by the identification of the ID module to ensure that the combination of multiple cards displayed complies with the rules set by the game.

[0053] like Figure 5 and Figure 6 As shown, a schematic diagram of the front of the electronic card is shown. Except for the frame, the entire front is an electronic paper display that can display poker or other game card content.

[0054] like Figure 5 As shown, in the embodiment of the electronic card, the card communication unit includes a signal contact, and the card communication unit communicates with the external device through the signal contact. Figure 5As shown, in the embodiment of the electronic card, there are two signal contacts and two power contacts; Figure 5 As shown, in the embodiment of the electronic card, the electronic card obtains power through two power contacts and an external power supply connection, and the electronic card obtains external control instructions through two signal contacts. In some embodiments not shown in the drawings, there may be more than two signal contacts, and the signal contacts may be a group of contacts corresponding to the communication interface.

[0055] like Figure 6 As shown, in the embodiment of the electronic card, no signal contact is set, only two power contacts are set; the card power supply unit in the electronic card obtains electrical energy through the two power contacts and the external power supply connection; the card control unit and the card communication unit inside the electronic card can realize wireless communication between the electronic card and the external control device.

[0056] like Figure 7 As shown, in the embodiment of the electronic card, the electronic card includes an electronic paper display screen, namely EPD, arranged on the upper layer, and a flexible circuit board FPC arranged below the electronic paper display screen, namely EPD.

The flexible circuit board FPC may also include a TFT driving array. The flexible circuit board FPC may be made of a transparent material. The main content of the card is displayed on the electronic paper display screen, namely EPD, and the other side of the card may not be set to display content. Figure 7 As shown in the figure, the cross-sectional diagram of the electronic paper-based card is mainly composed of three parts: EPD, FPCA, and card sealing and filling materials. The EPD is connected to the FPC by hot pressing, and other electronic components such as the Bluetooth module are welded on the FPC. Two metal sheets are led out from the bottom as power supply contacts; the outside is filled with card sealing materials to ensure that the electronic card is waterproof as a whole.

[0057] like Figure 8 As shown, in the embodiment of the electronic card, the electronic card includes two electronic paper display screens, namely EPD, which are respectively arranged on the two sides of the electronic card, and a flexible circuit board FPC is arranged between the two electronic paper display screens. The two electronic paper display screens can be driven separately, and different content can be displayed and updated at the same time. In this way, when setting different game content, the display content on both sides of the card can be changed. The two electronic paper display screens, namely EPD, are used to display the main content of the card, and the other is used to display the other side of the card. That is, the display content can be changed on both sides of the card, which makes the user experience of the card better, provides the opportunity to refresh the content on the back, and enriches various display combinations.

[0058] like Figure 7 and Figure 8As shown, in the embodiment of the electronic card, the electronic paper display screen, namely the EPD, can have its own TFT drive array, and the flexible circuit board FPC only performs other functions besides TFT drive. The flexible circuit board FPC can be provided with a card control unit, a card communication unit, and a card power supply unit.

[0059] In some embodiments of electronic cards not shown in the drawings, the flexible circuit board FPC can of course also integrate the TFT driving array.

[0060] like Fig. 9 As shown, an embodiment of an electronic card power supply device, i.e., a card box, includes: a card power supply module and a card box power supply module, wherein the card power supply module is electrically connected to the card box power supply module, and the card box power supply module provides power to the card power supply module. The card power supply module includes a power supply contact rail, and the power contacts of two or more electronic cards are in contact with the power supply contact rail, and the card power supply module provides power to the electronic card through the power supply contact rail. The number of rails corresponds to the number of power contacts, and the rails can be used to power multiple electronic cards at a time.

[0061] like Figures 10 to 12 As shown, in an embodiment of an electronic card power supply device, namely a card box, reference numeral 100 is a card box body, which is in the form of a vertical folder, with a first card slot 110 disposed on the bottom and a second card slot 120 disposed on the side. Figures 10 to 12 As shown, a simple schematic diagram of the card box is shown. The shape is similar to a folder, with a built-in PCBA board and lithium battery at the bottom. Multiple card slots are divided according to the thickness of the cards. Two metal shrapnel are reserved at the bottom of the slot corresponding to the cards for powering the cards.

[0062] Either the first card slot 110 or the second card slot 120 is selected as a power supply contact rail. The bottom or the top of the first card slot 110 is used as two power contacts of different polarities. Or the bottom or the top of the second card slot 120 is used as two power contacts of different polarities.

[0063] like Fig.13 As shown, in an embodiment of an electronic card power supply device, it also includes a card box control unit and a card box bus communication module, the card box bus communication module includes a signal contact rail; the signal contacts of two or more electronic cards are in contact with the signal contact rail; the card box bus communication module communicates with the electronic card through the contact rail. Fig.13 In the embodiment, corresponding to Figures 10 to 12 , either the first card slot 110 or the second card slot 120 is selected as a power supply contact rail; the remaining other rail is used as a signal contact rail.

[0064] like Fig.14 and Fig.15As shown, in an embodiment of an electronic card power supply device, the electronic card power supply device further includes a key module and an indicator light; the key module is electrically connected to the card box control unit; the indicator light is electrically connected to the card box control unit.

[0065] like Fig.14 and Fig.15 As shown, in an embodiment of an electronic card power supply device, a Bluetooth communication module is also included, and the card power supply device is connected to a smart mobile device via the Bluetooth communication module.

[0066] The electronic paper-based electronic cards, card power supply device and game system proposed in this application include at least one electronic card and a card box used in the game. The electronic card includes an FPCBA board, i.e. a flexible circuit board, a flexible electronic paper ink screen, and a structural shell; the card box includes a Bluetooth module, a control unit, and a power module. The electronic paper ink screen is used to display different card contents; the Bluetooth module is used for data reception and transmission, and the control unit is used to control the refresh and communication of the electronic paper ink screen; the shell is used to protect the ink screen and the internal circuit board; the card box supplies power to the electronic card through contacts when refreshing.

[0067] The electronic paper ink screen displays the card content, and the content is retained when the power is off, so no power is consumed when playing games. The flexible electronic paper ink screen + FPC control board + card sealing process are used to achieve an ultra-thin card design. Although it is not as thin as existing paper cards, it is basically as thick as an ID card or bank card, so it is also very practical.

[0068] The electronic paper ink screen can be controlled to refresh the displayed content through external terminals such as mobile phones or other external control systems. The card content can be changed at any time. One system can support multiple card games on the market without the need to purchase multiple sets of decks. New cards for the same game can be updated and added in a timely manner, and there is no need to purchase additional paper cards.

[0069] When the game is over, the cards are put into the card box and the card content is randomly refreshed via Bluetooth, eliminating the need to shuffle the cards manually.

[0070] Traditional paper cards are easily damaged. Flexible electronic paper + FPC control board + card sealing technology is used to increase the protection of the cards and make them more durable.

[0071] Displaying card content through other display technologies requires real-time power supply and high power consumption. Because of the built-in power supply battery, the mass is increased, the card is inconvenient to grasp, and the energy required for holding is increased.

[0072] It uses electronic paper display technology, which retains power when powered off and is powered only through contacts when refreshing. There is no need to connect other wires during gaming, which is closer to the gaming experience of traditional paper cards.

[0073] After the traditional paper card game is over, the cards need to be shuffled manually, which reduces the gaming experience. The electronic cards in this application are loaded into the card box for power supply after the game, and then the random content is refreshed through Bluetooth communication to complete the shuffling.

[0074] Traditional paper cards require one set of cards to play one game, and card game enthusiasts need to buy multiple sets of cards. The introduction of electronic cards, which displays the card content through electronic paper and switches the displayed content through a control system, can enable one system to experience multiple games, which is more cost-effective.

[0075] like Fig.16 , is the overall block diagram of the card game system based on electronic paper, including a card box and electronic cards. The electronic cards are composed of an ink screen, a control module, a Bluetooth module, and a power supply module; the card box is composed of a power supply module, a Bluetooth module, a control unit, a storage unit, an indicator light, and a button. The ink screen in the electronic card is used to display the content of each game card, such as the numbers and flower cards of playing cards; the power supply module in the electronic card, that is, the card power supply unit, is used to power the device. The power supply module may only have a voltage stabilizing device, and the power supply is connected to the power supply through metal contacts. The card box power supply module may include a rechargeable lithium battery, with a USB interface reserved for charging, and the card box power supply module may reserve multiple contact interfaces for powering the electronic card. A card box can correspond to at least one electronic card, or it can correspond to multiple electronic cards. The specific number of cards can be configured according to the needs of the game.

[0076] The Bluetooth module in the card box is used for wireless communication data transmission. The mobile device updates the designated game image data packet to the card box through the Bluetooth module, and the card box randomly sends the image data to each electronic card through the Bluetooth module. In some embodiments of the card box not shown in the drawings, the storage unit is used to receive multiple game card image data received by the Bluetooth module. The key module includes a toggle switch and a touch switch, which are mainly used for power on / off, reset, and setting.

[0077] In some electronic card embodiments not shown in the drawings, the control unit in the electronic card can cache the data received by the Bluetooth module and control the ink screen to display the cached image data. As a preference, a high-performance Bluetooth chip can be selected to replace the control unit and the Bluetooth module to reduce costs. When electronic cards are produced in large quantities, their costs can be minimized.

[0078] In some card box embodiments not shown in the accompanying drawings, the card box control unit can cache data packets received by a communication module such as a Bluetooth module and transfer them to a storage unit; at the same time, image data is obtained from the storage unit and sent to any electronic card through a random algorithm. As a preference, a high-performance MCU can be selected to replace the card box control unit and the storage unit; the indicator light is mainly used to switch lights of different colors to indicate different states.

[0079] like Fig.17 As shown, a usage process of a card game system based on electronic paper is as follows: first, bind the cards, insert all electronic cards into the card box slot, long press the reset button, the Bluetooth module on the card box starts scanning, communicates with all powered cards in turn, obtains the device address and numbers them, and displays the number on the electronic paper screen of each card. The blue light of the indicator flashes during the scanning process, and the green light is on when the scanning is completed. Then, bind the mobile phone, use the mobile phone to scan the QR code on the card box, and bind with the card box. After binding the mobile phone, you can play synchronous games, that is, use the mobile phone to scan the QR code on the card box, enter the mini program interface, select the specified game card for data synchronization, and the card image data is sent to the card box via Bluetooth and stored in the storage unit. During the data transmission process, the blue light of the indicator on the card box flashes, and the green light is on when the transmission is completed. After that, the user can take the card to play. If you need to shuffle or update the cards, insert all electronic cards into the card, press the refresh button, and the card box control module randomly selects the card image and sends it to each electronic card for refreshing. The blue light flashes during the refreshing process, and the green light is on when the refreshing is completed. After refreshing the cards, players can draw electronic cards and play the game according to the rules. After a round of games, players only need to insert all cards back into the card slots of the card box, press the refresh button, wait for the refresh to complete, and then continue the next round of games. If the user needs to change other games, just resynchronize the game, select other games on the phone again, synchronize the game, and then refresh all cards to experience various card games.
