[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0049] The embodiment of the present application provides a smart card. In practical applications, the smart card can be used in various scenarios such as identity authentication, attendance clocking, consumption payment, etc.

[0050] Smart card, also known as IC card (Integrated Circuit Card), smart card (Intelligent card), microcircuit card or microchip card.

[0051] Figure 1 A schematic diagram of the structure of a smart card in an embodiment of the present application is shown in FIG. Figure 1 As shown, the smart card may include: a connection area 10, an integrated circuit area 11 and a fingerprint identification display area 12;

[0052] The integrated circuit area 11 is located between the fingerprint identification display area 12 and the connection area 10;

[0053] A first connection end 13, located in the connection area 10;

[0054] An integrated circuit chip 14 is located in the integrated circuit region 11;

[0055] A fingerprint identification display device 15, located in the fingerprint identification display area 12;

[0056] The first connection end 13 is configured to serve as a power supply interface for the integrated circuit chip 14 and the fingerprint recognition display device 15, and as a communication connection interface between the integrated circuit chip 14 and the card recognition terminal when connected to the second connection end of the card recognition terminal;

[0057] The integrated circuit chip 14 is configured to send the user fingerprint information collected by the fingerprint recognition display device 15 to the card recognition terminal, so that the card recognition terminal confirms whether the user has passed the identity authentication based on the user fingerprint information; and is configured to receive the application information sent by the card recognition terminal after confirming that the user has passed the identity authentication based on the user fingerprint information; there may be multiple integrated circuit chips in the integrated circuit area 11;

[0058] The fingerprint recognition and display device 15 is configured to collect user fingerprint information and display application information.

[0059] In an exemplary embodiment, in a plane perpendicular to the smart card, a first connection terminal, a substrate and a cover plate are sequentially stacked in the connection area, and the first connection terminal is connected to the integrated circuit chip through a connecting wire passing through a via hole on the substrate.

[0060] In an exemplary embodiment, in a plane perpendicular to the smart card, a substrate base, a metal wiring layer, an integrated circuit chip and a cover plate are sequentially stacked in the integrated circuit area.

[0061] In an exemplary embodiment, in a plane perpendicular to the smart card, a base substrate, a fingerprint recognition display device and a transparent cover are sequentially stacked in the fingerprint recognition display area.

[0062] In an exemplary embodiment, the first connection end may be a Universal Serial Bus (USB) connection end.

[0063] In an exemplary embodiment, Figure 1 As shown, the fingerprint recognition display device 15 may include: a display area 151 and a fingerprint recognition area 152 arranged in the display area 151; wherein the display area 151 is configured to display application information; and the fingerprint recognition area 152 is configured to collect user fingerprint information.

[0064] In an exemplary embodiment, the fingerprint recognition area may be a local area in the display area. In this way, the resolution of the display area can be improved, thereby improving the display effect of the smart card. Figure 1 As shown, the fingerprint identification area 151 may be a local area located at the lower right corner of the display area 152 .

[0065] In an exemplary embodiment, the fingerprint recognition area may be the entire area of ​​the display area, so that the efficiency and accuracy of fingerprint recognition can be improved, thereby improving the convenience of the smart card.

[0066] In an exemplary embodiment, the fingerprint recognition display device may be an OLED (Organic Light Emitting Diode) fingerprint recognition display device. In this way, since the OLED fingerprint recognition display device is relatively thin and has a high display resolution, the thickness and weight of the smart card module can be reduced, thereby improving the user experience.

[0067] In an exemplary embodiment, the fingerprint recognition display device may be a flexible OLED fingerprint recognition display device. In this way, the module thickness and weight of the smart card can be reduced, and the display resolution of the smart card can be improved. Moreover, since the flexible material can be bent, the service life of the smart card can be increased, thereby improving the user experience.

[0068] In an exemplary embodiment, the integrated circuit chip is configured to receive prompt information sent by the card recognition terminal to instruct the user using the smart card to perform identity authentication; the fingerprint recognition display device is configured to display the prompt information. In this way, it is convenient for the user to know when fingerprint identity authentication is required, which can improve the user experience.

[0069] In an exemplary embodiment, after the fingerprint recognition display device displays application information, if the application information requires user confirmation, then the fingerprint recognition display device can also be configured to collect user fingerprint information for confirming the application information, and send the user fingerprint information for confirming the application information to the integrated circuit chip; the integrated circuit chip can also be configured to send the user fingerprint information for confirming the application information to the card recognition terminal.

[0070] In actual applications, the smart card provided in the embodiment of the present application can be connected to different card recognition terminals in different application scenarios to display different application information in different application scenarios, so as to realize multiple uses of one card. For example, when the smart card is applied to the payment scenario, the application information can be consumption information. Then, the user can enter the fingerprint information through the smart card to confirm the consumption information, that is, the user can use the fingerprint to make payment through the smart card. In this way, there is no need for the user to scan the QR code, enter the payment password, etc. The operation is very simple, the payment is faster, and it is suitable for groups of all ages. For another example, when the smart card is applied to the attendance punching scene, the application information can be attendance information. Then, the user can enter the fingerprint information through the smart card to confirm the attendance information, that is, the user can use the fingerprint to punch the card through the smart card.

[0071] From the above content, it can be seen that the smart card provided in the embodiment of the present application has the following beneficial effects:

[0072] First, in the process of information interaction between the card recognition terminal and the smart card, convenient information display is achieved through the fingerprint recognition display device, which can facilitate users to browse information and increase the information interaction experience. There is no need to equip the card recognition terminal with additional large-scale display equipment, which can reduce the cost of the card recognition terminal and facilitate deployment.

[0073] Second, the fingerprint recognition display device is used to collect user fingerprint information to achieve fast and secure identity authentication, which can avoid theft caused by the loss of smart cards and greatly improve the security of smart cards. In addition, since there is no need to enter a password, the operation is simple, and it is more convenient and quick to use, suitable for users of all ages. Furthermore, it can also avoid the tedious process of password recovery after forgetting the password, and it can also avoid adding additional input devices to the card recognition terminal, which can reduce the cost of the card recognition terminal and facilitate deployment.

[0074] Third, since the first connection end in the smart card is connected to the second connection end of the card identification terminal, the card identification terminal can supply power to the smart card. Compared with the radio frequency power supply method in some technologies, it can ensure the normal operation of the fingerprint identification display device; and compared with the method of integrating the multi-function card into the smart phone, the user does not have to worry about the multi-function card being unusable due to insufficient power of the smart phone. When the user uses the smart card, there is no need for battery power. As long as the card identification terminal can work normally, generally speaking, the user will not be troubled by the sudden power outage and inability to use the smart card. In addition, there is no need to build a battery into the smart card, which further reduces the thickness and weight of the smart card module.

[0075] Fourthly, since the communication connection between the smart card and the card identification terminal is established by connecting the first connection end in the smart card with the second connection end in the card identification terminal, the integrated circuit chip in the smart card and the card identification terminal can communicate directly through the first connection end in the smart card. Therefore, compared with the method of integrating a multi-function card into a smart phone, when the user uses the smart card, as long as the card identification terminal can work normally, the user will not be troubled by the inability to use the smart card due to poor network signal.

[0076] In an exemplary embodiment, in a plane perpendicular to the smart card, i.e. Figure 2A or Figure 2B In the cross section shown, the smart card may include: a first connection terminal 13, a substrate 21, a protective layer 22, a metal wiring layer 23, an integrated circuit chip 14, a fingerprint identification display device 15 and a cover plate 24.

[0077] The first connection terminal 13 is disposed on the surface of the substrate 21 away from the fingerprint identification display device 15, and is exposed to the outside, so as to be connected to the second connection terminal of the card identification terminal. The first connection terminal 13 can be connected to the metal wiring layer through a connecting wire in a via 25 passing through the substrate 21 and the protective layer 22, and connected to the integrated circuit chip 14 disposed on the upper layer of the metal wiring layer (the side of the metal wiring layer away from the substrate). In a direction parallel to the smart card, the first connection terminal 13 can be disposed on the side of the substrate 21 away from the fingerprint identification display device 15.

[0078] The protection layer 22 is disposed on the upper surface of the base substrate 21 (ie, the surface of the base substrate facing the cover plate), and the protection layer can be made of organic materials such as PET (polyethylene terephthalate) plastic.

[0079] The fingerprint identification display device 15 is disposed between the protection layer 22 and the cover plate 24 .

[0080] The metal wiring layer 23 is disposed on a side of the protection layer 22 away from the base substrate, and can be disposed on the same layer as the fingerprint identification display device 15 .

[0081] The integrated circuit chip 14 is disposed between the metal wiring layer 23 and the cover plate 24 .

[0082] In an exemplary embodiment, the cover plate may be made of a flexible material, so as to reduce the thickness and weight of the module of the smart card.

[0083] The following is an explanation by region.

[0084] First, the connection area will be described.

[0085] like Figure 2A or Figure 2BAs shown, in a plane perpendicular to the smart card, the first connection terminal 13, the base substrate 21, the protection layer 22 and the cover plate 24 may be stacked in sequence in the connection area 10.

[0086] In an exemplary embodiment, the cover plate located in the connection area may be made of an opaque material.

[0087] Next, the integrated circuit region will be described.

[0088] like Figure 2A or Figure 2B As shown, in a plane perpendicular to the smart card, a base substrate 21 , a protection layer 22 , a metal wiring layer 23 , an integrated circuit chip 14 and a cover plate 24 may be sequentially stacked in the integrated circuit area 11 .

[0089] In an exemplary embodiment, the cover plate located in the integrated circuit region may be made of an opaque material.

[0090] Then, the fingerprint recognition display area is described.

[0091] like Figure 2A or Figure 2B As shown, in a plane perpendicular to the smart card, a base substrate 21, a protective layer 22, a fingerprint identification display device 15 and a cover plate 24 may be stacked in sequence in the fingerprint identification display area 12.

[0092] In an exemplary embodiment, the cover plate located in the fingerprint identification display area may be made of a transparent material.

[0096] In an exemplary embodiment, the second pixel unit may be part or all of the pixels of the first pixel unit. In this way, part (or all) of the pixels of the fingerprint recognition display device are used to provide the detection light to illuminate the fingerprint recognition area located in the fingerprint recognition display device, and then reflected to the photosensitive unit through the fingerprint. Next, due to the different reflections of the detection light by the "valleys" and "ridges" of the user's fingerprint, the illumination reaching different photosensitive units is different, and the amount of charge generated by different photosensitive units is different in the same time. Therefore, according to the difference between the amount of charge generated at the "valleys" and "ridges" of the user's fingerprint, the fingerprint valleys and ridges can be collected, and thus the user's fingerprint information is collected.

[0097] In an exemplary embodiment, Figure 2A or Figure 2B As shown, in the fingerprint recognition area, each photosensitive unit 27 is arranged between two adjacent pixel units 26. That is, in the fingerprint recognition area, the pixel units of the pixel array and the photosensitive units of the optical sensor array are arranged alternately.

[0100] The following description is made by taking the display area as AMOLED and the fingerprint recognition area as PMOLED as an example.

[0104] The first light emitting structure layer may include: a second interlayer dielectric layer 307, a first anode 308, a pixel definition layer (Pixel Definition Layer, PDL) 309, a first organic light emitting layer 310 and a cathode 302 stacked in sequence; wherein the first anode 308 is connected to the drain electrode of the first thin film transistor through a via hole on the second interlayer dielectric layer 307; the pixel definition layer 309 is used to define a pixel opening area; the first organic light emitting layer 310 is provided with an electroluminescent material and is arranged in the pixel opening area defined by the pixel definition layer 309; and the cathode 302 is arranged on the first organic light emitting layer 310. In addition, the first light emitting structure layer may also include an encapsulation layer ( Figure 3 not shown).

[0105] In an exemplary embodiment, the first thin film transistor in the first driving structure layer may have multiple ( Figure 3 The display area is illustrated by taking only one light-emitting unit and one first thin film transistor as an example).

[0106] The fingerprint recognition area is described.

[0107] In an exemplary embodiment, Figure 3 As shown, in a plane perpendicular to the smart card, the fingerprint recognition area may include: a substrate 301, a second driving structure layer disposed on the substrate, and a fingerprint recognition device layer and a second light-emitting structure layer disposed on the second driving structure layer;

[0108] The second driving structure layer may include: a second thin film transistor disposed on the substrate 301, and the second thin film transistor may include: a second semiconductor layer 313, a second gate 311, a first interlayer dielectric layer 305, and a second source-drain metal layer 312 (which may include a source electrode and a drain electrode) stacked in sequence; wherein the second source-drain metal layer 312 is connected to the second semiconductor layer 313 through a via hole on the first interlayer dielectric layer 305;

[0109] The fingerprint recognition device layer may include: a photosensitive sensor 314 stacked in sequence, a transparent electrode 315, a second interlayer dielectric layer 307, and a second anode 316; the photosensitive sensor 314 is disposed on the drain electrode of the second thin film transistor;

[0110] The second light emitting structure layer may include: a second interlayer dielectric layer 307, a third anode 317, a pixel definition layer 309, a second organic light emitting layer 318 and a cathode 302 stacked in sequence; the second organic light emitting layer is arranged in the pixel opening area defined by the pixel definition layer; the pixel definition layer 309 is used to define the pixel opening area; the second organic light emitting layer 318 is provided with an electroluminescent material and is arranged in the pixel opening area defined by the pixel definition layer 309; the cathode 302 is arranged on the second organic light emitting layer 318. In addition, the second light emitting structure layer may also include an encapsulation layer ( Figure 3 not shown).

[0111] In an exemplary embodiment, the second thin film transistor in the second driving structure layer may have a plurality of ( Figure 3 The fingerprint recognition area is illustrated by taking only one light-emitting unit, one photosensitive unit and one second thin film transistor as an example).

[0112] like Figure 3 As shown, the first thin film transistor for controlling the display and the second thin film transistor for controlling fingerprint recognition are arranged in the same layer, and the light-emitting structure layer (including the first light-emitting structure layer and the second light-emitting structure layer) and the fingerprint recognition device layer are also arranged in the same layer. In this way, when preparing the fingerprint recognition display device, the display area and the fingerprint recognition area can be manufactured synchronously and share the power supply, which not only makes the fingerprint recognition display device thinner and lighter, but also reduces the cost.

[0113] In an exemplary embodiment, the first thin film transistor and the second thin film transistor can be manufactured using the same LTPS (Low Temperature Poly-silicon) process.

[0114] In an exemplary embodiment, the above-mentioned photosensor may be, for example, a PN photosensor, a PIN photosensor, a P-Si (P-type silicon) photosensor, or the like.

[0116] In an exemplary embodiment, a metal wiring layer can be formed on the surface of the protective layer away from the substrate by bonding technology, thereby reducing the thickness and weight of the smart card module.

[0118] In an exemplary embodiment, the above-mentioned integrated circuit chip may include: a display driver IC, a first main control IC and a second main control IC, wherein the display driver IC is used to drive at least one of the pixel unit array in the display area and the pixel unit array in the fingerprint recognition area; the first main control IC is used to control at least one of the pixel unit array in the display area and the pixel unit array in the fingerprint recognition area, and the second main control IC is used to control the photosensitive unit array in the fingerprint recognition area.

[0119] Based on the same inventive concept, an embodiment of the present application provides an information processing method. In practical applications, the information processing method can be applied to the smart card in one or more of the above embodiments.

[0120] Figure 4A A flowchart of the information processing method in the embodiment of the present application is shown in FIG. Figure 4A As shown, the information processing method may include:

[0121] Step 401: After the smart card is inserted into the card identification terminal, the smart card collects user fingerprint information for identity authentication, and sends the user fingerprint information for identity authentication to the card identification terminal, so that the card identification terminal confirms whether the user has passed the identity authentication based on the user fingerprint information for identity authentication;

[0122] Step 402: The smart card receives and displays the application information sent by the card identification terminal after the user passes the identity authentication.

[0123] Exemplarily, when a user needs to use a smart card, the smart card can be inserted into a card identification terminal. When the first connection end of the smart card is connected to the second connection end of the card identification terminal, the user can perform identity authentication on the smart card. In this way, the smart card can collect the user's fingerprint information for identity authentication through the fingerprint identification display device, and then send the user's fingerprint information to the card identification terminal. Next, the card identification terminal can confirm whether the user has passed the identity authentication based on the user's fingerprint information. When it is determined that the user has passed the identity authentication, the card identification terminal can send the corresponding application information to the smart card. Finally, the smart card can display the application information to the user through the fingerprint identification display device. In this way, the misappropriation caused by the loss of the smart card can be avoided, and the security of the smart card can be greatly improved. Moreover, the operation is simple and it is more convenient and quick to use. In addition, convenient information display can be achieved, which can facilitate users to browse information and increase information interaction experience.

[0124] In an exemplary embodiment, in order to remind the user to authenticate the identity, after the smart card is inserted into the card identification terminal, a prompt message for instructing the user using the smart card to authenticate the identity can be displayed through the fingerprint identification display device of the smart card, or a preset light effect for instructing the user using the smart card to authenticate the identity can be displayed through the fingerprint identification display device of the smart card, or a prompt can be provided by controlling the indicator light on the card identification terminal to display a preset color. Here, the embodiments of the present application are not specifically limited.

[0125] In an exemplary embodiment, taking displaying prompt information as an example, step 401 may include steps 4011 to 4013:

[0126] Step 4011: the smart card receives prompt information sent by the card identification terminal after the smart card is inserted into the card identification terminal, which is used to instruct the user using the smart card to perform identity authentication;

[0127] Exemplarily, when the user needs to use a smart card, the smart card can be inserted into a card identification terminal. When the first connection end of the smart card is connected to the second connection end of the card identification terminal, it indicates that the user has successfully inserted the smart card into the card identification terminal. At this time, the card identification terminal can send the prompt information to the smart card to instruct the user to perform fingerprint identity authentication.

[0128] Step 4012: the smart card displays a prompt message;

[0129] Step 4013: When the user performs identity authentication, the smart card collects the user's fingerprint information for identity authentication.

[0149] In an exemplary embodiment, the application scenario of the smart card is identity authentication, and the cloud service system is a public security identity authentication system. Fig. 6A and Figure 6BAs shown, when the cardholder needs to provide identity proof, the cardholder can insert the smart card into the card recognition terminal configured by the public security identity authentication system. At this time, the card recognition terminal can detect that the smart card has been inserted, and the first indicator light (such as a red light) of the card recognition terminal can light up. At the same time, the card recognition terminal can supply power to the OLED fingerprint recognition display device through the USB connection end of the smart card. At this time, the display area of ​​the OLED fingerprint recognition display device will be lit, and the card recognition terminal can send prompt information for prompting the cardholder to perform identity authentication to the integrated circuit chip of the smart card through the USB connection end of the smart card, wherein the prompt information includes: information 601 for indicating that the application scenario is identity authentication and information 602 for indicating the location of the fingerprint recognition area.

At this time, the card recognition terminal can detect that the smart card has been inserted, and the first indicator light (such as a red light) of the card recognition terminal can light up. At the same time, the card recognition terminal can supply power to the OLED fingerprint recognition display device through the USB connection end of the smart card. At this time, the display area of ​​the OLED fingerprint recognition display device will be lit, and the card recognition terminal can send prompt information for prompting the cardholder to perform identity authentication to the integrated circuit chip of the smart card through the USB connection end of the smart card, wherein the prompt information includes: information 701 for indicating the application scenario and information 702 for indicating the location of the fingerprint recognition area. Next, the integrated circuit chip of the smart card can control and drive the OLED fingerprint recognition display device to display information 701 for indicating the application scenario and information 702 for indicating the location of the fingerprint recognition area to remind the cardholder to perform fingerprint recognition; after the fingerprint recognition area of ​​the smart card collects the fingerprint information of the cardholder, the fingerprint recognition area will send the fingerprint information of the cardholder to the integrated circuit chip, so that the integrated circuit chip sends the fingerprint information of the cardholder to the card recognition terminal through the USB connection end. Then, the card recognition terminal can perform fingerprint identity verification on the cardholder through the attendance system based on the received fingerprint information of the cardholder. When the fingerprint recognition verification of the cardholder is passed, the second indicator light (such as a green light) of the card recognition terminal can light up. At the same time, the card recognition terminal can send the attendance information such as the cardholder's information, clock-in time, clock-in date, etc. from the attendance system to the integrated circuit chip, so that the integrated circuit chip drives and controls the OLED fingerprint recognition display device to display the attendance information, so as to remind the cardholder to confirm the attendance information. Finally, after the cardholder has verified that the information is correct, he can confirm the fingerprint recognition according to the prompt. At this time, the fingerprint recognition area of ​​the smart card can collect the fingerprint information of the cardholder again, indicating that the cardholder confirms that the attendance information displayed by the OLED fingerprint recognition display device is correct and confirms that the clock-in is completed with this attendance information. Then, the fingerprint recognition area can send the fingerprint information of the cardholder to the integrated circuit chip, so that the integrated circuit chip sends the fingerprint information of the cardholder and the attendance information to the card recognition terminal through the USB connection end, and then, the card recognition terminal uploads the fingerprint information of the cardholder and the attendance information to the cloud service system through the computer device or wireless network. In this way, the cardholder completes an attendance clock-in process through the smart card.

[0151] In an exemplary embodiment, the application scenario of the smart card is consumption payment, and the cloud service system is a consumption system. Fig. 8A and Figure 8BAs shown, when the cardholder checks out at a shopping mall or supermarket or other consumption place, the cardholder can insert the smart card into the card recognition terminal configured by the merchant's consumption system. At this time, the card recognition terminal can detect that the smart card has been inserted, and the first indicator light (such as a red light) of the card recognition terminal can light up. At the same time, the card recognition terminal can supply power to the OLED fingerprint recognition display device through the USB connection end of the smart card.

Next, the integrated circuit chip of the smart card can control and drive the OLED fingerprint recognition display device to display information 801 for indicating the application scenario and information 802 for indicating the location of the fingerprint recognition area to remind the cardholder to perform fingerprint recognition; after the fingerprint recognition area of ​​the smart card collects the fingerprint information of the cardholder, the fingerprint recognition area will send the fingerprint information of the cardholder to the integrated circuit chip, so that the integrated circuit chip sends the fingerprint information of the cardholder to the card recognition terminal through the USB connection end. Then, the card recognition terminal can perform fingerprint identity verification on the cardholder through the consumption system based on the received fingerprint information of the cardholder. When the fingerprint recognition verification of the cardholder is passed, the second indicator light (such as a green light) of the card recognition terminal can light up. At the same time, the card recognition terminal can send the consumption information such as the cardholder's information, payment details, account balance, etc. from the consumption system to the integrated circuit chip, so that the integrated circuit chip drives and controls the OLED fingerprint recognition display device to display the consumption information, so as to remind the cardholder to confirm the consumption information. Finally, after the cardholder has verified that the information is correct, the cardholder can confirm the fingerprint recognition according to the prompts. At this time, the fingerprint recognition area of ​​the smart card can collect the cardholder's fingerprint information again. At this time, it indicates that the cardholder confirms that the consumption information displayed by the OLED fingerprint recognition display device is correct. The cardholder confirms that the payment is completed with this consumption information. Then, the fingerprint recognition area can send the cardholder's fingerprint information to the integrated circuit chip, so that the integrated circuit chip sends the cardholder's fingerprint information and the consumption information to the card recognition terminal through the USB connection end, and then, the card recognition terminal uploads the cardholder's fingerprint information and the consumption information to the cloud service system or wireless network through a computer device or a wireless network. In this way, the cardholder completes a consumption payment process through a smart card. This method is convenient for the cardholder to confirm the consumption amount, and can avoid the inconvenience caused by the smartphone being out of network, arrears, and out of power. In addition, fingerprint authentication payment through a smart card does not require a password and is very convenient, fast and safe.
