Description

Technical Field

[0001] This invention relates to the technical field of intelligent office equipment and human-computer interaction, and more specifically to an e-ink screen name tag and application system with an embedded control module. Background Technology

[0002] With the rise of smart offices and personalized workplace culture, traditional paper or fixed employee badges can no longer meet employees' needs for personalized and dynamic identification. E-ink screens, due to their low power consumption and paper-like display effect, are gradually being applied to smart employee badges that can refresh information, and can maintain their color for years even when completely powered off.

[0003] Existing electronic ink displays typically include an electrophoretic layer and a driver IC (Integrated Circuit). The electrophoretic layer is a display layer composed of an array of microcapsules, while the driver IC is used to drive the movement of ink particles within the microcapsules to display corresponding patterns. The driver IC and the electrophoretic layer are generally connected via an SPI (Serial Peripheral interface) or an I2C (Inter Integrated Circuit Bus) interface.

[0004] To edit the content displayed on the e-ink screen, an external control module is required. This module can be an MCU (Microcontroller Unit) or an FPGA (Field-Programmable Gate Array). The MCU connects to the driver IC via a parallel interface, while the FPGA connects to the driver IC via an SPI or I2C interface. The editing process involves a mobile phone or computer sending the edited content to the control module. The control module first saves the edited content and then transmits it to the driver IC according to the communication protocol. The driver IC then drives the ink particles at the corresponding positions to move, causing the edited content to appear on the electrophoretic layer.

[0005] In existing e-ink displays, the interfaces for connecting external control modules are typically encapsulated within the casing and not exposed. Therefore, editing the display content of an e-ink display is not easy for ordinary users. First, they need a printed circuit board containing the control module; then, they need to disassemble the e-ink display casing, locate the external connection interface, and connect the corresponding pins of the control module according to the interface's pinout; next, they need to install driver software on a computer, establish a connection between the computer and the control module, enter an authentication password, and then program the control module's MCU or FPGA to send the edited content. All these operations require a certain level of expertise—understanding the interface, installing the driver, knowing and correctly entering the authentication password—which is too difficult for ordinary users and makes it inconvenient for them to independently set the display content of the e-ink display.

[0006] Moreover, in the existing technology, the driver IC is integrated on the e-ink screen and cannot be disassembled or reused. When the e-ink screen can no longer be used due to severe image retention or other malfunctions caused by aging, the driver IC chip can only be discarded along with the e-ink screen, which makes the overall cost of the e-ink screen high. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an e-ink screen nameplate with an embedded control module, that is, to set a pluggable control module inside the e-ink screen nameplate, so that the control module can be detachably connected to the e-ink screen nameplate, and it is also convenient for mobile terminals to establish a connection and communication with the control module, so that users can independently set the display content of the e-ink screen anytime and anywhere.

[0008] The technical solution of this invention is to provide an e-ink display badge with an embedded control module, comprising an e-ink display badge and a control module. The e-ink display badge includes a shell, within which are disposed an e-ink display, a battery, and an e-ink display interface. The battery powers the e-ink display, and the e-ink display interface enables the e-ink display to connect to an external power source. The control module includes a microcontroller and an e-ink display interface. The e-ink display interface is pluggably electrically connected to the e-ink display interface to enable the microcontroller to connect to the e-ink display. The microcontroller is used to edit the display content of the e-ink display. The microcontroller includes a wireless communication unit and a QR code. The QR code stores information corresponding to the microcontroller, enabling external devices to establish a signal connection with the microcontroller by scanning the QR code, thereby allowing external devices to read and write to the microcontroller through the wireless communication unit.

[0009] Compared with the prior art, the e-ink screen nameplate with an embedded control module of the present invention has the following advantages: 1. External devices can establish a signal connection with the microcontroller by scanning the QR code, thereby transmitting information to the microcontroller. The microcontroller then transmits the received information to the e-ink screen for display. In other words, after scanning the microcontroller's QR code, the user can edit the content displayed on the e-ink screen directly on the external device, achieving "one-scan editing." This eliminates the need for complex tasks such as manually installing drivers, configuring IP addresses, and entering PIN codes, allowing users to independently set the e-ink screen's display content anytime, anywhere, greatly enhancing the user experience. The QR code can be a static QR code printed on the control module, eliminating the need for battery power; or it can be a dynamic QR code generated by the control module, offering high security.

[0010] 2. The control module and e-ink screen are pluggable and electrically connected. This means that while users experience the convenience of "scan and edit", the control module and e-ink screen can be manufactured separately without integration, reducing production complexity. The pluggable and electrically connected design also makes assembly convenient. Furthermore, if either the control module or the e-ink screen fails, it can be quickly replaced, preventing the failure of one from rendering the other unusable. This results in high product reusability and significantly reduced product costs.

[0011] Preferably, the microcontroller includes a QR code generation unit, which dynamically generates the QR code. The microcontroller can transmit the newly generated QR code to an e-ink screen for external display. This structure, where the QR code is dynamically generated by the generation unit and displayed on the e-ink screen, improves security, avoiding the risk of a static QR code being permanently compromised and remotely tampered with, and also adds a technological feel and enhances the user experience.

[0012] Preferably, the wireless communication unit includes a Bluetooth chip, and the QR code stores the name or MAC address of the microcontroller. External devices can quickly pair with the microcontroller via Bluetooth by scanning the QR code, and then establish Bluetooth communication with the microcontroller. Using this structure, the QR code can encode the name or Bluetooth MAC address of the microcontroller (e.g., the Bluetooth QR code content is BLUETOOTH:XX_XX;MAC:AA:BB:CC:DD:EE:FF). (Or just the device name, used for device discovery). After scanning, the external device's system (such as Android) will automatically pop up a pairing request and complete the pairing, eliminating the need to manually turn on Bluetooth, manually search for devices, or enter a 4-6 digit PIN code.

[0013] Preferably, the wireless communication unit includes a Wi-Fi chip or a Bluetooth / Wi-Fi dual-mode chip. The QR code stores the microcontroller's public key, MAC address, and channel. External devices can scan the QR code to connect to the microcontroller via Wi-Fi and transmit signals through the Wi-Fi local area network. Using this structure, the QR code can encode the microcontroller's public key, MAC address, and channel (e.g., the DPP QR code content is DPP:CH=1 / 11). PK=...; MAC=... (used for network access control). After scanning, the external device's system (e.g., Android) will automatically send the Wi-Fi password of its local area network to the microcontroller via the DPP protocol. After the microcontroller connects to Wi-Fi, it becomes a local area network device and can communicate with external devices on the same network.

[0014] Preferably, the control module includes an e-ink screen driving circuit. The microcontroller is electrically connected to the e-ink screen driving circuit, and the e-ink screen driving circuit is electrically connected to the e-ink screen interface. The e-ink screen interface is electrically connected to the e-ink screen interface to enable the e-ink screen driving circuit to be electrically connected to the e-ink screen. The e-ink screen driving circuit receives data output by the microcontroller for editing the e-ink screen and drives the e-ink screen to display the corresponding pattern. With this structure, the e-ink screen driving circuit and the microcontroller are integrated into the control module. The e-ink screen on the e-ink badge only has a display layer composed of a microcapsule array. Therefore, the cost of the e-ink badge is lower, and the loss due to damage is minimal. The e-ink screen interface and the e-ink screen interface serve as the interfaces for the electrical connection between the e-ink screen driving circuit and the e-ink screen, and can use either an SPI interface or an I2C interface.

[0015] Preferably, the e-ink badge includes an e-ink drive circuit. This drive circuit is electrically connected to both the e-ink screen and the e-ink interface. The e-ink interface is electrically connected to the e-ink interface to connect the microcontroller to the e-ink drive circuit. The e-ink drive circuit receives data from the microcontroller for editing the e-ink screen and drives the e-ink screen to display the corresponding pattern. With this structure, the e-ink screen on the badge includes an e-ink drive circuit and a display layer composed of a microcapsule array. The drive circuit drives the movement of ink particles within the microcapsules to display the corresponding pattern. This reduces the cost of the control module and mitigates losses caused by accidental loss or damage. The e-ink interface, serving as the interface for electrical connection between the microcontroller and the e-ink drive circuit, can utilize an MCU parallel interface (also known as an 8080 interface).

[0016] Preferably, the outer shell of the e-ink display nameplate has an embedding slot, the e-ink interface is located within the embedding slot, and the control module is detachably mounted within the embedding slot, allowing for pluggable electrical connection between the e-ink interface and the e-ink display interface. With this structure, when the e-ink interface and the e-ink display interface are electrically connected, the control module is located within the embedding slot, facilitating a neat, integrated structure with the e-ink display nameplate. This makes it aesthetically pleasing when placed on a workstation or hung on a workstation screen, preventing the control module from protruding from the e-ink display nameplate and affecting its appearance.

[0017] Preferably, the control module can slide into or out of the embedding slot. A guide rail is provided on one side wall of the control module and the slot wall, and a guide groove is provided on the other side. The guide rail and guide groove slide in cooperation to guide the sliding of the control module. This structure, with the guide rail and guide groove sliding in cooperation to guide the control module into the embedding slot, facilitates the alignment and efficient connection of the e-ink screen interface with the e-ink screen interface.

[0018] Preferably, one of the side wall of the control module and the wall of the embedding slot is provided with a snap-fit ​​protrusion, and the other is provided with a snap-fit ​​groove. When the e-ink interface is electrically connected to the e-ink interface, the snap-fit ​​protrusion and the snap-fit ​​groove engage and lock together. With this structure, when the e-ink interface is electrically connected to the e-ink interface, the control module is not only located in the embedding slot, but is also snapped together with the embedding slot, which has a safety function for the control module and prevents the control module from accidentally falling out.

[0019] The present invention also provides an application system for the above-mentioned e-ink screen nameplate with embedded control module, which allows users to quickly, conveniently and personally set the display content of the e-ink screen.

[0020] The technical solution of this invention is to provide an application system for an e-ink display ID card with an embedded control module, including a mobile terminal APP and the e-ink display ID card with an embedded control module as described above. The mobile terminal APP includes a QR code scanning module, an ID card template library module, an image and text editing module, and a data synchronization module. The workflow of the QR code scanning module includes, in sequence, calling the camera on the mobile terminal to scan the QR code, parsing the information about the microcontroller in the QR code, establishing a signal connection with the microcontroller, and automatically jumping to the editing interface of the e-ink display ID card with an embedded control module. The image and text editing module includes text input function, image upload function, font adjustment function, color inversion function, and automatic layout function, used to set text and images and adjust font, color, and layout in the editing interface. The ID card template library module includes several templates of different styles, and the templates include combinations of fonts, colors, layouts, and images, used to call them in the editing interface. The data synchronization module is used to send the content of the editing interface to the microcontroller through the wireless communication unit. The microcontroller receives the content of the editing interface and triggers the e-ink screen to refresh so that the e-ink screen displays the content of the editing interface.

[0021] Compared with existing technologies, the e-ink screen ID card application system with an embedded control module of the present invention has the following advantages: by scanning the QR code of the microcontroller with a mobile terminal APP, an external device can directly establish a signal connection with the microcontroller, and the user can edit the content to be displayed on the e-ink screen on the external device, realizing "one scan and edit". Moreover, the mobile terminal APP also has different style templates for editing the content to be displayed on the e-ink screen, which can be quickly called. When editing the content, users can independently input text, upload pictures, adjust fonts, set colors, black and white inversion, and automatic layout, which makes it convenient for users to quickly, easily and personally set the content displayed on the e-ink screen.

[0022] Preferably, the microcontroller includes a QR code generation unit for dynamically generating the QR code, and an initial QR code generated by the QR code generation unit is displayed on the e-ink screen. When the microcontroller receives the content of the editing interface, the QR code generation unit generates a new QR code, and the microcontroller triggers the e-ink screen to refresh so that the e-ink screen displays the content of the editing interface and the newly generated QR code. With this structure, although the QR code is dynamic, the update frequency is very low. The QR code generation unit only generates a new QR code after the microcontroller receives the content of the editing interface, and the power consumption is comparable to that of static QR codes. The content of the editing interface and the newly generated QR code are displayed together on the e-ink screen. When editing the displayed content of the e-ink screen next time, only scanning the latest QR code can establish a signal connection with the microcontroller. That is, as long as the e-ink screen badge with an embedded control module is in the user's possession, the user can always independently set the displayed content of the e-ink screen without worrying about the leakage of old QR codes, resulting in extremely high security.

[0023] Preferably, the application system further includes a cloud service system, which stores historical editing information of the e-ink screen and provides the latest resource downloads from the employee badge template library. The mobile terminal APP also includes a version management module, which records historical editing information of the e-ink screen and sends it to the cloud service system. The version management module can also request historical editing information of the e-ink screen from the cloud service system and supports restoring historical editing information of the e-ink screen. With this structure, the version management module of the mobile terminal APP backs up the historical editing information of the e-ink screen, enabling the employee badge 1 to review the displayed content and synchronize the historical editing information of the e-ink screen to the cloud service system. The historical editing information of the e-ink screen synchronized to the cloud service system can also be downloaded, backed up, and synchronized by multiple external devices. The cloud service system also provides the latest resource downloads from the employee badge template library, which allows multiple external devices to easily set the display content of the e-ink screen.

[0024] Preferably, the cloud service system also includes an AI model, which provides auxiliary design solutions for the content displayed on the e-ink screen. This structure, with the AI ​​model providing auxiliary design solutions, allows users to personalize the content displayed on the e-ink screen.

[0025] Preferably, the microcontroller includes a security authentication module for supporting device authentication and encrypted data transmission; the mobile terminal APP also includes a user account management module for associating with the security authentication module and setting user accounts and login passwords bound to the security authentication module; the cloud service system further stores information about the user accounts bound to the security authentication module. With this structure, the user account management module of the mobile terminal APP can set user accounts and login passwords bound to the security authentication module. When a user connects to the microcontroller through the mobile terminal APP, the security authentication module can verify the user account and login password, thus improving security.

[0026] Preferably, the cloud service system also includes a batch management interface, which allows a single mobile terminal app to batch and uniformly set initial information for multiple e-ink ID cards with embedded control modules. With this structure, the batch management interface supports enterprise-level batch and uniform setting of the initial display information for the e-ink ID cards with embedded control modules.

[0035] To better understand this application, various aspects of this application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0036] In the accompanying drawings, the thickness, size, and shape of the objects have been slightly exaggerated for illustrative purposes. The drawings are for illustrative purposes only and are not drawn to scale.

[0037] It should also be understood that the terms "comprising," "having," "including," and "containing," when used in this specification, indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof. Furthermore, when expressions such as "...at least one" appear after a list of listed features, they modify the entire listed feature, not individual elements in the list.

[0038] Example 1

[0039] like Figures 1 to 3As shown, the e-ink badge with an embedded control module of the present invention includes an e-ink badge 1 and a control module 2. The e-ink badge 1 includes a shell, which includes a front shell, a middle frame, and a back cover. An e-ink screen, an e-ink interface 1-1, and a battery are disposed inside the shell. An embedding groove 1-4 is provided on the middle frame, and the e-ink interface 1-1 is disposed in the embedding groove 1-4. The battery is embedded in the bottom of the embedding groove 1-4. The control module 2 includes a microcontroller and an e-ink interface 2-1. The control module 2 can slide into or out of the embedding groove 1-4 to mate the e-ink screen. Port 2-1 is pluggably electrically connected to the e-ink interface 1-1. The side wall of the control module 2 is provided with a guide groove 2-2 and a snap-fit ​​protrusion 2-3. The wall of the embedded slot 1-4 is provided with a guide strip 1-2 and a snap-fit ​​groove 1-3. The guide strip 1-2 slides into the guide groove 2-2 to guide the sliding of the control module 2. When the control module 2 slides into the embedded slot 1-4, causing the e-ink interface 2-1 to electrically connect with the e-ink interface 1-1, the snap-fit ​​protrusion 2-3 engages with the snap-fit ​​groove 1-3 and snaps together, and the battery is limited by the control module 2. The battery powers the e-ink screen. When the e-ink interface 2-1 is electrically connected to the e-ink interface 1-1, the microcontroller is electrically connected to the e-ink screen, allowing the microcontroller to edit the display content of the e-ink screen.

[0040] like Figure 4 As shown, the microcontroller can be a mainstream MCU on the market, integrating a main control chip, a security authentication module, a storage unit, a power management unit, and a wireless communication unit. A QR code is printed on the outside of the microcontroller, storing information corresponding to the microcontroller. This allows external devices to establish a signal connection with the microcontroller by scanning the QR code, enabling communication between the external device and the microcontroller via the wireless communication unit. The security authentication module supports device authentication and encrypted data transmission.

[0041] In this embodiment, the wireless communication unit employs a Bluetooth / Wi-Fi dual-mode chip. The QR code encodes the microcontroller's public key, MAC address, and channel (e.g., the DPP QR code content is DPP:CH=1 / 11;PK=...;MAC=..., used for network access). After scanning by an external device such as a mobile phone (e.g., Android), it automatically sends the Wi-Fi password of its local area network to the microcontroller via the DPP protocol. Once connected to Wi-Fi, the microcontroller becomes a local area network device, enabling communication with external devices within the same network. That is, external devices can connect to the microcontroller via Wi-Fi by scanning the QR code, and then transmit signals with the microcontroller through the Wi-Fi local area network. Thus, users can input content into the microcontroller using external devices such as mobile phones. The main control chip stores the input content in the storage unit and then outputs it to the e-ink screen, i.e., editing the display content of the e-ink screen.

[0042] In other embodiments, the wireless communication unit may employ a Bluetooth chip, and the QR code may encode the name of the microcontroller or its Bluetooth MAC address (e.g., the Bluetooth QR code content is BLUETOOTH:XX_XX;MAC:AA:BB:CC:DD:EE:FF or just the device name, used for device discovery). After scanning by the system of an external device such as a mobile phone (e.g., Android), a pairing request will automatically pop up and pairing will be completed, thereby establishing Bluetooth communication with the microcontroller.

[0043] Control module 2 also includes an e-ink screen driving circuit. The microcontroller and the e-ink screen driving circuit are integrated on the same PCB and electrically connected. The e-ink screen driving circuit is electrically connected to e-ink interface 2-1. E-ink interface 2-1 and e-ink interface 1-1 serve as interfaces for the electrical connection between the e-ink screen driving circuit and the e-ink screen, both using SPI interfaces. The e-ink screen driving circuit and the microcontroller are integrated into control module 2. The e-ink screen on the e-ink badge 1 only has a display layer composed of a microcapsule array. The main control chip outputs the data stored in the storage unit to the e-ink screen driving circuit, which then provides a high voltage to drive the e-ink screen, causing it to display the corresponding pattern.

[0044] Example 2

[0045] like Figure 5As shown, the difference between this embodiment and embodiment 1 is that the electronic ink screen on the ink screen badge 1 is provided with an ink screen driving circuit and a display layer composed of a microcapsule array. The ink screen driving circuit is used to drive the movement of ink particles in the microcapsules to display the corresponding pattern. The ink screen driving circuit is also electrically connected to the ink screen interface 1-1. Thus, the ink screen driving circuit is no longer set in the control module 2. The ink screen interface 2-1 and the ink screen interface 1-1 serve as the interface for the microcontroller to be electrically connected to the ink screen driving circuit. The mainstream MCU parallel interface (also known as the 8080 interface) can be used.

[0046] Example 3

[0047] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the microcontroller further includes a QR code generation unit, the QR code is dynamically generated by the QR code generation unit, and the microcontroller can transmit the newly generated QR code to the electronic ink screen for external display.

[0048] To avoid excessive power consumption by the QR code generation unit, its QR code update frequency can be reduced to a very low level. For example, it can be configured so that the QR code generation unit only generates a new QR code after the microcontroller receives edited content transmitted from an external device, and the latest edited content and the latest generated QR code are displayed together on the e-ink screen. That is, the QR code generation unit only generates a new QR code when the content displayed on the e-ink screen is updated. In this way, the power consumption of the QR code generation unit is comparable to that of a static QR code.

[0049] Since the QR code is updated every time the content displayed on the e-ink screen is updated, the next time the content of the e-ink screen needs to be edited, only by scanning the latest QR code can a signal connection be established with the microcontroller. In other words, as long as the e-ink screen ID card with the embedded control module is in the user's possession, the user can always set the content of the e-ink screen independently without worrying about the old QR code being leaked, making it extremely secure.

[0050] Example 4

[0051] like Figure 7 As shown, the application system of the e-ink screen ID card with embedded control module of the present invention includes a mobile terminal APP, a cloud service system, and the e-ink screen ID card with embedded control module described in any of the above embodiments.

[0052] The mobile terminal APP includes a user account management module, which is used to associate with the security authentication module and set the user account and login password bound to the security authentication module. Each time a user scans a QR code to connect to the microcontroller using the mobile terminal APP, the security authentication module can verify the user account and login password. Only after successful verification can communication with the microcontroller be established, thus improving security. The cloud service system is used to store the user account information bound to the security authentication module.

[0053] The mobile terminal APP includes a QR code direct connection module, a work badge template library module, an image and text editing module, and a data synchronization module. The QR code direct connection module's workflow includes, in sequence, calling the mobile terminal's camera to scan the QR code, parsing the information about the microcontroller in the QR code, establishing a signal connection with the microcontroller, and automatically redirecting to the editing interface of the e-ink work badge with an embedded control module. The image and text editing module includes text input, image upload, font adjustment, color inversion, and automatic layout functions, used to set text and images and adjust fonts, colors, and layouts in the editing interface. The work badge template library module includes several templates of different styles, each including combinations of fonts, colors, layouts, and images, used for calling upon in the editing interface. The data synchronization module transmits the content of the editing interface to the microcontroller via the wireless communication unit. The microcontroller receives the content of the editing interface and triggers an e-ink screen refresh to display the content of the editing interface on the e-ink screen.

[0054] When editing the content to be displayed on the e-ink screen, the mobile app can quickly call up templates of different styles. When editing content, users can independently input text, upload images, adjust fonts, set colors for black and white contrast, and automatically format the content. This allows users to quickly, conveniently, and personally customize the content displayed on the e-ink screen.

[0055] If the application system of the e-ink badge with an embedded control module of the present invention adopts the e-ink badge with an embedded control module as described in Embodiment 3, that is, the microcontroller integrates a QR code generation unit for dynamically generating the QR code, and the e-ink screen displays the initial QR code generated by the QR code generation unit, then when the microcontroller receives the content of the editing interface, the QR code generation unit generates a new QR code, and the microcontroller triggers the e-ink screen to refresh so that the e-ink screen displays the content of the editing interface and the newly generated QR code. Although the QR code is dynamic, the update frequency is very low, and the power consumption is extremely low.

[0056] The mobile terminal APP includes a version management module. This module records historical editing information of the e-ink screen and sends it to the cloud service system, synchronizing the historical editing information of the e-ink screen to the cloud service system. The historical editing information synchronized to the cloud service system can also be downloaded, backed up, and synchronized by multiple external devices. The cloud service system stores the historical editing information of the e-ink screen. The version management module can request the historical editing information of the e-ink screen from the cloud service system and supports restoring the historical editing information of the e-ink screen. In essence, the cloud service system backs up the historical editing information of the e-ink screen, allowing the e-ink screen ID card 1 to review the displayed content.

[0057] The cloud service system also provides the latest resource downloads from the employee badge template library, and includes an AI model. This AI model assists in designing content for the e-ink screen display. Users can download the employee badge template library from the cloud service system to any mobile terminal, allowing any external device to easily configure the e-ink screen display content. Users can also use the AI ​​model to design personalized templates and images to their liking.

[0058] The cloud service system also has a batch management interface, which is used by a single mobile terminal APP to batch uniformly set the initial information of multiple e-ink screen nameplates with embedded control modules. That is, the batch management interface supports enterprise-level batch uniform setting of the initial display information of the e-ink screen nameplates with embedded control modules.

[0059] The workflow of the e-ink display ID card application system with an embedded control module of the present invention is as follows: The user scans the QR code of the microcontroller using a mobile terminal APP. The scanning direct connection module in the mobile terminal APP automatically calls the camera on the mobile terminal to scan the QR code, parses the information about the microcontroller in the QR code (such as device ID and temporary token), establishes a signal connection with the microcontroller, and automatically jumps to the editing interface of the e-ink screen ID card that can be embedded with the control module. If the security authentication module in the microcontroller detects that the user has not logged in with the user account and login password bound to it, the user account management module of the mobile terminal APP can guide the user to log in to the account; The version management module can request historical editing information (including current display content) of the e-ink screen from the cloud service system. The graphic editing module can load the current employee badge display content as a draft, enter editing mode, input text, upload images, adjust fonts, set colors for black and white contrast, and format the text. During the editing process, the graphic editing module can also call other styles of templates in the employee badge template library module for editing, and can also download the latest templates from the employee badge template library in the cloud service system, or design personalized templates and images that suit one's own preferences through the AI ​​model for editing. After the image and text editing module completes the editing, the data synchronization module encrypts and packages the content of the editing interface and sends it to the microcontroller via Bluetooth / Wi-Fi. The microcontroller receives data from the editing interface, and the security authentication module authenticates the device identity. If authentication is successful, a partial refresh of the e-ink screen is triggered to complete the content update. Specifically, the data from the editing interface is output to the e-ink screen driving circuit, which then provides a high voltage to drive the e-ink screen, causing it to display the corresponding pattern. During this process, the QR code generation unit generates a new QR code, which is also output to the e-ink screen driving circuit and displayed on the e-ink screen along with the latest edited content. Thus, the update of the employee badge display content is completed.
