[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, a splicing electronic paper display device is provided, which includes multiple splicing modules.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are only for the convenience of describing this application 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 application.

[0027] Please see Figures 1 to 4 , Figure 1 This is a two-dimensional splicing diagram of the splicing type electronic paper display device of this application. Figure 2 It is a 3D mosaic. Figure 3 It is a 3D diagram of the splicing module and Figure 4 yes Figure 3An exploded view is shown; as illustrated, the splicing electronic paper display device 1 of this embodiment is mainly applied in the field of color electronic paper display, and can achieve multi-directional splicing to form a two-dimensional or three-dimensional electronic paper display structure. In this embodiment, the splicing electronic paper display device 1 includes multiple splicing modules 11. Each splicing module 11 includes an electronic paper display unit 12, a frame 13, and a magnetic liquid (not shown in the figure). The electronic paper display unit 12 is used to display graphics or text. The electronic paper display unit 12 includes electronic paper 121 (not shown in the figure) and NFC 122. NFC (Near Field Communication) is an emerging technology that allows devices using NFC technology to exchange data when they are close to each other. It evolved from contactless radio frequency identification (RFID) and interconnection technology, integrating inductive card readers, inductive cards, and point-to-point communication functions on a single chip. NFC122 is integrated into the e-paper unit 121, allowing the e-paper unit 121 to refresh the display screen via a matching driver module, and also enabling remote control of the display screen via an external Wi-Fi module, eliminating the need for battery-powered color-changing refreshes. The e-paper display unit 12 is housed within a frame 13. The frame 13 protects the e-paper display unit 12 and allows multiple e-paper display units 12 to be combined.

[0028] As described above, the frame 13 includes at least one hollow magnetic frame 131. The magnetic frame 131 is a hollow polygonal prism or cylinder. Magnetic liquid is disposed within the magnetic frame 131. The magnetic liquid possesses both the fluidity of a liquid and the magnetism of a solid magnetic material. It is a stable colloidal liquid composed of magnetic solid particles with a diameter on the nanometer scale, a base liquid, and a surfactant. This fluid has no magnetic attraction when static, but exhibits magnetism when an external magnetic field is applied. The magnetic liquid enables the magnetic frame 131 to have omnidirectional magnetic attraction. Thus, the magnetic frame 131 of the frame 13 of each splicing module 11 has omnidirectional magnetic attraction, and when multiple splicing modules 11 are spliced ​​together, multi-directional splicing can be achieved through the corresponding magnetic frames 131, thereby forming a two-dimensional or three-dimensional electronic paper display structure.

[0029] The splicing-type electronic paper display device 1 of this embodiment features a hollow magnetic frame 131 within the frame 13 of the splicing module 11. Magnetic liquid is then injected into the magnetic frame 131, giving it omnidirectional magnetic attraction. This allows multiple splicing modules 11 to be sequentially connected and magnetically attracted through their corresponding magnetic frames 131, forming splicing combinations of different patterns. This results in a specific shape (two-dimensional or three-dimensional) electronic paper display structure, enabling diverse splicing of electronic paper display devices and creating larger areas or more three-dimensional shapes for the display screen. This effectively enhances the application range and user experience of the electronic paper display device. The splicing-type electronic paper display device 1 of this embodiment can be applied to various indoor scenarios, achieving multi-functional uses such as wall decoration, toy building blocks, and art installations. It also boasts advantages such as energy saving, environmental friendliness, diverse colors, and convenient splicing.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, there are three splicing modules 11. Each frame 13 includes three hollow magnetic borders 131, which form a triangle. The three splicing modules 11 are spliced ​​together by sequentially connecting the corresponding magnetic borders 131 to form a two-dimensional electronic paper display planar structure or a three-dimensional (conical) electronic paper display solid structure. It should be understood that the above description uses only three splicing modules 11 as an example to illustrate multiple splicing modules. However, this application is not limited to this. Those skilled in the art can select different numbers of splicing modules 11 according to actual needs, and then combine them with the above splicing method to form electronic paper display structures of other shapes.

[0031] See also Figure 3 and Figure 4 As shown, in this embodiment, the magnetic frame 131 is provided with a filling port 1311 and a sealing cap 1312. Magnetic fluid is placed inside the magnetic frame 131 through the filling port 1311. The sealing cap 1312 is disposed at the filling port 1311 and seals the magnetic fluid inside the magnetic frame 131. Thus, after the magnetic properties of the magnetic fluid weaken, it can be replaced or maintained by opening the sealing cap 1312. The filling port 1311 is a circular hole connecting to the hollow interior of the magnetic frame 131, and the sealing cap 1312 is a circular plug.

[0032] The frame 13 also includes multiple magnetic borders 131 and multiple connecting frames 132. Adjacent magnetic borders 131 are connected by connecting frames 132. The magnetic borders 131 and connecting frames 132 can be connected via a tubular connection. Multiple magnetic borders 131 are connected by multiple connecting frames 132 to form a polygonal frame. Specifically, as... Figure 4As shown, the frame 13 includes three hollow magnetic frame borders 131 and three connecting frames 132. The three magnetic frame borders 131 are connected sequentially through the three connecting frames 132 to form a triangular frame. It should be understood that the above description only uses a triangular frame as an example to illustrate the frame 13. However, this application is not limited to this. Those skilled in the art can select different shapes of frame 13 according to actual needs, and then combine them with the above splicing method to form other shapes of electronic paper display structures.

[0033] See also Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a support plate 14 is provided on the inner side of the frame 13. The electronic paper display unit 12 is disposed on the support plate 14. Each splicing module 11 also includes a cover plate 15. The cover plate 15 is disposed on the frame 13. The electronic paper display unit 12 is located between the cover plate 15 and the support plate 14, and the cover plate 15 and the support plate 14 cooperate to fix the electronic paper display unit 12 inside the frame 13. The hollow portions of multiple magnetic frame 131 are connected sequentially through multiple connecting frames 132. In this way, the filling port 1311 and the sealing cover 1312 can be provided on only one magnetic frame 131 to realize the filling of magnetic liquid into multiple magnetic frame 131 and subsequent replacement or maintenance.

[0034] Please see Figure 5 This is another exploded view of the splicing module of this application; as shown in the figure, in this embodiment, the splicing module 11 includes two electronic paper display units 12. The two electronic paper display units 12 are disposed within the frame 13, and the display surfaces of the two electronic paper display units 12 face the two sides of the frame 13, thus realizing double-sided display of the splicing module 11. The splicing module 11 also includes two cover plates 15. The two cover plates 15 are disposed on both sides of the frame 13, and the two cover plates 15 cooperate with the support plate 14 to fix the two electronic paper display units 12 within the frame 13.

[0035] In summary, this application provides a splicing type electronic paper display device. A hollow magnetic frame is set on the frame of the splicing module, and then magnetic liquid is poured into the magnetic frame to give the magnetic frame a universal magnetic attraction force. In this way, multiple splicing modules can be spliced ​​into different patterns by sequentially connecting the corresponding magnetic frames, thereby forming an electronic paper display structure of a specific shape (two-dimensional or three-dimensional). This realizes the diversified splicing of electronic paper display devices and effectively improves the application range and user experience of electronic paper display devices.
