[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] This invention provides a segment-based electronic paper splicing display device, comprising: a plurality of splicing display units; each splicing display unit includes an electronic paper module and a driving PCB board, wherein the electronic paper module is composed of an electronic paper film and an FPC backplane with multiple driving electrode segments.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] like Figure 1 As shown, an embodiment of the present invention provides a segment code type electronic paper splicing display device, which includes at least: a plurality of splicing display units 1;

[0050] The splicing display unit 1 includes an electronic paper module 2 and a driving PCB board 3 connected to the electronic paper module 2; the electronic paper module 2 includes an electronic paper film and an FPC backplate; the FPC backplate is provided with several electrode segments;

[0051] The driving PCB board 3 includes a Bluetooth chip 31, a synchronization signal detection interface 32, and a segment code driving chip 33.

[0052] The Bluetooth chip 31 is used to receive the electrode segment data packets corresponding to each sub-image in the image to be displayed generated by the server; the electrode segment data packets are used to characterize the electrode segments corresponding to each sub-image when it is displayed; each sub-image is formed by dividing the image to be displayed according to each splicing display unit 1.

[0053] The synchronization signal detection interface 32 is used to receive the synchronization trigger signal transmitted by the Bluetooth base station through the synchronization signal line after all Bluetooth chips 31 receive the corresponding electrode segment data packets, and send a drive signal to the segment code driver chip 33 according to the synchronization trigger signal.

[0054] The segment code driver chip 33 is used to drive the electronic paper module 2 to display the sub-image corresponding to the splicing display unit 1 according to the data packets of each electrode segment and the driving signal.

[0055] Understandably, the electronic paper module 2 includes an electronic paper film and an FPC backplane. The electronic paper film utilizes electrophoresis or bistable display technology, enabling it to maintain a static image without continuous power supply, significantly reducing energy consumption. Compared to traditional LED or LCD screens, it offers significant energy-saving advantages in long-term display applications. The FPC backplane has electrode segments; by controlling the on / off state of different electrode segments, precise driving of the electronic paper is achieved, simplifying the design of the driving circuit and improving display stability.

[0056] It's important to note that the color display principle of electronic paper films is primarily based on electrophoresis or bistable display technology. Image display is achieved by controlling the movement of charged particles within microcup or microcapsule. In electrophoretic display technology, electronic paper films consist of millions of microcup (or microcapsules), each containing charged particles of different colors suspended within a transparent fluid. For example, common four-color electronic paper contains red, blue, yellow, and white particles, with red and blue particles carrying a positive charge and yellow and white particles carrying a negative charge. When an electric field of different polarities is applied externally, positively charged particles move towards the negative pole, while negatively charged particles move towards the positive pole. This causes particles of a certain color to float to the top of the microcup, where they are reflected by external light, forming a visible image and color display. Because electronic paper uses a reflective display method and does not rely on backlighting, its color display effect is similar to traditional paper, maintaining good visibility even in sunlight. In addition, electronic paper has bistable characteristics, meaning that it can maintain the display state without continuous power supply after the image stabilizes, which greatly reduces energy consumption and makes it particularly suitable for low-power, long-term static display applications.

[0057] Understandably, the Bluetooth chip 31 enables wireless data transmission, avoiding complex wired connections. This not only simplifies wiring and improves system flexibility and scalability but also effectively reduces the risk of signal interference. The server segments the image to be displayed based on the layout of the splicing units and generates electrode segment data packets corresponding to the electrode segments on the FPC backplane. This ensures that each splicing display unit 1 accurately obtains the necessary driving data, avoiding unnecessary processing and improving the overall efficiency of data transmission and display. The synchronization signal detection interface 32 receives the synchronization trigger signal from the Bluetooth base station via the synchronization signal line, ensuring that all splicing display units 1 refresh synchronously after data reception. This avoids image misalignment, tearing, or flickering caused by asynchronous refresh between units, improving the display consistency and stability of the large-screen splicing. The segment code driver chip 33 controls the corresponding electrode segments on the FPC backplane based on the electrode segment data packets and the synchronization trigger signal to drive the electronic paper film to display content. Compared to traditional dot-matrix driving, the segment code control method reduces the complexity of the driving circuit while improving the accuracy of the display response, ensuring clear and stable image quality.

[0058] In a preferred embodiment, the electronic paper module 2 further includes a PS protective film;

[0059] The FPC backplate surface is printed with segment code electrode patterns.

[0060] The electronic paper film is disposed on the upper layer of the FPC backplane;

[0061] The PS protective film is disposed on the upper layer of the electronic paper film;

[0062] The FPC backplane is connected to the segment code driver chip 33;

[0063] The electronic paper film is connected to the FPC backplane.

[0064] Understandably, the PS protective film covering the surface of the electronic paper film effectively protects the electronic paper from external environmental influences such as dust, moisture, or scratches, improving screen durability and preventing performance degradation due to external forces. The FPC backplane uses a segment-based electrode pattern, making the driving method simpler and more efficient. The segment-based electrode layout precisely matches the display requirements of the electronic paper, reducing unnecessary signal interference and optimizing the design of the driving circuit, allowing the driving chip to directly control the corresponding electrodes, improving response speed and display accuracy. Furthermore, the segment-based design can be customized according to customer needs, meeting the display effects and layout requirements of different application scenarios, enhancing system flexibility and customizability. The electronic paper film is directly bonded to the upper layer of the FPC backplane, enabling efficient transmission of electrode signals to the inside of the electronic paper, improving pixel control precision, and thus ensuring image clarity and stability. The FPC backplane connects to the segment driver chip 33, making electrode control more flexible and enabling precise driving of the electronic paper display based on the input electrode segment data packets, achieving a stable display effect with low power consumption and high contrast.

[0065] In an optional embodiment, the electrode segment is connected to the drive pin of the drive PCB board 3 via a conductive trace.

[0066] It is understandable that connecting the electrode segments to the drive pins of the drive PCB board 3 via conductive traces enables efficient signal transmission between the electrode segments and the drive circuit. This connection method allows the drive chip to control each electrode segment more precisely, thereby improving the accuracy and consistency of the display effect, helping to reduce system failures and power consumption, and improving overall performance.

[0067] In one specific embodiment, the server generates the electrode segment data packets corresponding to each sub-image in the image to be displayed in the following manner:

[0068] The image to be displayed is acquired and then cut into several sub-images according to the physical arrangement of each splicing display unit 1; wherein each sub-image corresponds to one splicing display unit 1;

[0069] The electrode segments corresponding to each sub-image are determined based on the electrode segment layout of the sub-image and the corresponding splicing display unit 1FPC backplane.

[0070] Based on the electrode segments corresponding to each sub-image, generate an electrode segment data packet containing the identifier of the corresponding electrode segment.

[0071] It is understandable that by dividing the image to be displayed into several sub-images according to the physical arrangement of the splicing display unit 1, and assigning a corresponding splicing display unit 1 to each sub-image, accurate image display can be ensured, avoiding misalignment or distortion of the displayed content. This allows each splicing unit to display its corresponding portion of the image content, improving the accuracy of the display effect. Based on the electrode segment layout of the sub-images and the FPC backplane of the splicing display unit 1, the electrode segments corresponding to each sub-image are determined. This process optimizes the precision of electrode control, enabling the drive signal to be accurately transmitted to the corresponding electrode segment, thereby improving the clarity and stability of the image display. By generating electrode segment data packets containing corresponding electrode segment identifiers, efficient data transmission and processing are achieved. Each electrode segment data packet clearly identifies the electrode segment that needs to be driven, avoiding redundant data transmission and improving the efficiency of data transmission and the response speed of the display system.

[0072] In a preferred embodiment, the step of cutting the image to be displayed into several sub-images according to the physical arrangement of each splicing display unit 1 includes:

[0073] Based on the physical arrangement of each splicing display unit 1, determine the position and display area shape of each splicing unit in the display device;

[0074] According to the position of each splicing unit and the shape of the display area, the image to be displayed is cut into several sub-images; each sub-image corresponds to a splicing display unit 1 and the shape of the sub-image is consistent with the shape of the display area of ​​the corresponding splicing display unit 1.

[0075] Understandably, determining the position and display area shape of each splicing unit within the display device based on the physical arrangement of each splicing display unit 1 ensures precise layout and positioning of each unit within the entire display system, thereby avoiding image misalignment and content asymmetry. This is particularly important for large-screen splicing displays, guaranteeing seamless integration between splicing display units 1 and achieving better display effects. Dividing the image to be displayed into several sub-images according to the position and display area shape of each splicing unit efficiently segments the large image into sub-images suitable for each splicing display unit 1, ensuring that the display content of each sub-image is completely consistent with the display area shape of the corresponding unit, avoiding shape mismatch, incomplete display, or distortion during the display process. Each sub-image corresponds to one splicing display unit 1, and the shape of the sub-image is consistent with the display area shape of the corresponding splicing display unit 1. This design principle ensures perfect matching between the display content and the splicing unit, avoiding overlap or omission of image display areas and guaranteeing a complete and accurate image display effect.

[0076] Specifically, based on the data packets and driving signals of each electrode segment, the electronic paper module 2 is driven to display the sub-image corresponding to the splicing display unit 1, including:

[0077] The target driving pin in the driving PCB board 3 is determined based on the electrode segment identifier in the electrode segment data packet.

[0078] Based on the driving signal, a driving voltage is generated for the target driving pin so that the electronic paper film displays the sub-image corresponding to the splicing display unit 1.

[0079] It should be noted that, based on the electrode segment identifier in the electrode segment data packet, the specific position and function of each electrode segment in the display unit can be accurately identified, thereby determining the target driving pin corresponding to that electrode segment. This allows for more precise control of the electrode segments, ensuring that the display area of ​​each display unit correctly receives the corresponding voltage signal. Based on the driving signal, a driving voltage for the target driving pin is generated, and the magnitude and polarity of the driving voltage are adjusted according to the display requirements of the sub-image. By adjusting the applied voltage, the position of the color particles in the electrode segment can be controlled, thereby achieving color changes in the electronic paper film, ultimately enabling each splicing display unit 1 to display its corresponding sub-image content.

[0080] Optionally, the electronic paper module 2 is square in shape.

[0081] Understandably, this design choice makes the layout and arrangement of the e-paper module 2 in the splicing display system simpler, more standardized, and easier to manage. The square shape is symmetrical, facilitating even distribution throughout the display device and avoiding space waste or uneven arrangement caused by irregular shapes. Simultaneously, the seams between the square e-paper module 2 and other splicing display units 1 are easier to seamlessly connect, improving the overall display continuity. Furthermore, the square design helps simplify the manufacturing process and reduce production costs. The uniformity in size and shape of the square modules makes mass production more efficient, reducing the need for customization of modules with different shapes during production.

[0083] The server is used to generate electrode segment data packets corresponding to each sub-image in the image to be displayed, and send each electrode segment data packet to the Bluetooth base station; wherein, the electrode segment data packet is used to characterize the electrode segment corresponding to each sub-image when it is displayed; each sub-image is formed by dividing the image to be displayed according to each splicing display unit 1;

[0084] The Bluetooth base station is used to receive electrode segment data packets, send the electrode segment data packets to the display device, and send a synchronization trigger signal to the display device after all the electrode segment data packets corresponding to all sub-images have been sent.

[0085] The display device is used to receive electrode segment data packets through Bluetooth chip 31, and when it receives the synchronization trigger signal transmitted by Bluetooth base station through synchronization signal line, it sends a drive signal to segment code driver chip 33 according to the synchronization trigger signal through synchronization signal detection interface 32; and drives electronic paper module 2 to display sub-images corresponding to splicing display unit 1 according to the electrode segment data packets and drive signals through segment code display chip.
