[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “top” and “bottom” are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply 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 invention.

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

[0050] The spliced ​​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 backplane; the FPC backplane is provided with a plurality of 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 represent 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 driving signal to the segment code driving chip 33 according to the synchronization trigger signal;

[0054] The segment code driving chip 33 is used to drive the electronic paper module 2 to display the sub-image corresponding to the spliced ​​display unit 1 according to the electrode segment data packets and the driving signals.

[0055] It is understandable that the electronic paper module 2 includes an electronic paper membrane and an FPC backplane. The electronic paper membrane uses electrophoresis or bistable display technology to maintain a static image without continuous power supply, greatly reducing energy consumption. Compared with traditional LED or LCD screens, it has significant energy-saving advantages in long-term display application scenarios. Electrode segments are provided on the FPC backplane, and the precise driving of the electronic paper is achieved by controlling the on and off of different electrode segments, which simplifies the design of the driving circuit and improves the display stability.

[0056] It should be noted that the color display principle of the electronic paper film is mainly based on electrophoresis or bistable display technology, and image display is achieved by controlling the movement of charged color particles in microcups or microcapsules. In electrophoretic display technology, the electronic paper film is composed of millions of microcups (or microcapsules), each of which has charged particles of different colors suspended inside it, and these particles are distributed in a transparent fluid. For example, the common four-color electronic paper contains four color particles of red, blue, yellow, and white, of which the red and blue particles are positively charged, and the yellow and white particles are negatively charged. When an electric field of different polarities is applied externally, the positively charged particles will move toward the negative pole, while the negatively charged particles will move toward the positive pole, so that particles of a certain color float to the top of the microcup and are reflected by external light to form a visible image and color display. Since the electronic paper adopts a reflective display mode and does not rely on backlighting, its color display effect is similar to that of traditional paper, and it still has good visibility in the sun. In addition, e-paper has a bistable characteristic, that is, after the image stabilizes, it can maintain the display state without continuous power supply, which greatly reduces energy consumption and makes it particularly suitable for low-power, long-term static display application scenarios.

[0057] It is understandable that the Bluetooth chip 31 realizes wireless data transmission, avoids complex wired connections, simplifies wiring, improves the flexibility and scalability of the system, and effectively reduces the risk of signal interference. The server divides the image to be displayed according to the layout of the splicing unit, and generates an electrode segment data packet corresponding to the electrode segment of the FPC backplane, so that each splicing display unit 1 can accurately obtain the driving data required by itself, avoid unnecessary processing, and improve the overall efficiency of data transmission and display. The synchronization signal detection interface 32 receives the synchronization trigger signal of the Bluetooth base station through the synchronization signal line to ensure that all splicing display units 1 are refreshed synchronously after the data reception is completed, avoiding image dislocation, tearing or flickering caused by asynchronous refresh between units, and improving the display consistency and stability of large-screen splicing. The segment code driver chip 33 controls the corresponding electrode segment on the FPC backplane according to the electrode segment data packet and the synchronization trigger signal to drive the electronic paper film to display the content. Compared with the traditional dot matrix drive, the segment code control method reduces the complexity of the drive circuit, while improving the accuracy of the display response and ensuring the clarity and stability of the picture quality.

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

[0059] The surface of the FPC backplane is printed with a segment code electrode pattern;

[0060] The electronic paper film is arranged on the upper layer of the FPC back plate;

[0061] The PS protective film is arranged 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 back plate.

[0064] It is understandable that the PS protective film covers the surface of the electronic paper film, which can effectively protect the electronic paper from external environmental influences, such as dust, moisture or scratches, improve the durability of the screen, and avoid performance degradation caused by external forces. The FPC backplane adopts a segment code electrode pattern, making the driving method more concise and efficient. The segment code electrode layout can accurately match the display requirements of the electronic paper, reduce unnecessary signal interference, and optimize the design of the driving circuit, so that the driver chip can directly control the corresponding electrode, improve the response speed and display accuracy. In addition, the segment code design can be customized according to customer needs to meet the display effects and layout requirements of different application scenarios, and enhance the flexibility and customizability of the system. The electronic paper film is directly attached to the upper layer of the FPC backplane, so that the electrode signal can be efficiently transmitted to the inside of the electronic paper, improving the control accuracy of the pixel points, thereby ensuring the clarity and stability of the image. The FPC backplane is connected to the segment code driver chip 33, making the electrode control more flexible, and can accurately drive the electronic paper display according to the input electrode segment data packet, achieving a stable display effect with low power consumption and high contrast.

[0065] In an optional embodiment, the electrode segments are connected to driving pins of the driving PCB board 3 via conductive traces.

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

[0067] In a 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] Acquire an image to be displayed, and cut the image to be displayed into a plurality of 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] Determine the electrode segment corresponding to each sub-image according to the sub-image and the corresponding electrode segment layout of the spliced ​​display unit 1FPC backplane;

[0070] According to the electrode segments corresponding to each sub-image, an electrode segment data packet including the identification of the corresponding electrode segment is generated.

[0071] It can be understood that by cutting the image to be displayed into several sub-images according to the physical arrangement of the splicing display unit 1, and specifying the corresponding splicing display unit 1 for each sub-image, the accurate display of the image can be ensured, the dislocation or distortion of the display content can be avoided, so that each splicing unit can display the image content of its corresponding part, and the accuracy of the display effect is improved. According to the sub-image and the electrode segment layout of the splicing display unit 1FPC backplane, the electrode segment corresponding to each sub-image is determined. This process optimizes the accuracy of electrode control, so that the drive signal can be accurately transmitted to the corresponding electrode segment, thereby improving the clarity and stability of the image display. By generating an electrode segment data packet containing the corresponding electrode segment identifier, efficient data transmission and processing is achieved. Each electrode segment data packet clearly identifies the electrode segment 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 a plurality of sub-images according to the physical arrangement of each spliced ​​display unit 1 includes:

[0073] According to 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] It is understandable that according to the physical arrangement of each splicing display unit 1, the position and display area shape of each splicing unit in the display device are determined, which can ensure that the layout and positioning of each splicing unit in the entire display system are accurate and correct, thereby avoiding the problem of image dislocation and misalignment of display content. This is especially important for large-screen splicing display, which can ensure seamless connection between splicing display units 1 and achieve better display effects. 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. This step can efficiently divide the large image into sub-images adapted to 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 a 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 can ensure a perfect match between the display content and the splicing unit, avoid overlapping or omission of the image display area, and ensure that the image display effect is complete and accurate.

[0076] Specifically, according to the electrode segment data packets and the driving signals, the electronic paper module 2 is driven to display the sub-image corresponding to the spliced ​​display unit 1, including:

[0077] Determine the target drive pin in the drive PCB board 3 according to the electrode segment identifier in the electrode segment data packet;

[0078] According to the driving signal, a driving voltage of the target driving pin is generated so that the electronic paper film displays the sub-image corresponding to the spliced ​​display unit 1 .

[0079] It should be noted that, according to 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, and then the target drive pin corresponding to the electrode segment can be determined. In this way, the control of the electrode segment can be more precise, thereby ensuring that the display area of ​​each display unit correctly receives the corresponding voltage signal. According to the drive signal, the drive voltage of the target drive pin is generated, and the magnitude and polarity of the drive voltage are adjusted according to the display requirements of the sub-image. By adjusting the application of voltage, the position of the color particles in the electrode segment can be controlled, thereby realizing the color change of the electronic paper membrane, and finally making each spliced ​​display unit 1 display its corresponding sub-image content.

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

[0081] It is understandable that this design choice makes the layout and arrangement of the electronic paper module 2 in the spliced ​​display system more concise, standardized and easy to manage. The square shape is symmetrical, which is convenient for uniform distribution throughout the display device, avoiding the problem of space waste or uneven arrangement caused by irregular shapes. At the same time, the seams between the square electronic paper module 2 and other spliced ​​display units 1 are easier to achieve seamless docking, which improves the consistency of the overall display effect. In addition, the square design helps to simplify the manufacturing process and production costs. Due to the consistency of the size and shape of the square modules, mass production becomes more efficient, reducing the need for customization of modules of different shapes during the production process.

[0083] The server is used to generate an electrode segment data packet corresponding to each sub-image in the image to be displayed, and send the electrode segment data packet to the Bluetooth base station; wherein the electrode segment data packet is used to represent 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 the electrode segment data packet, send the electrode segment data packet to the display device, and send a synchronization trigger signal to the display device after the electrode segment data packets corresponding to all sub-images are sent;

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