Description

Technical Field

[0001] The utility model relates to the technical field of electronic paper displays, and in particular to a segment code electronic paper structure. Background Art

[0002] As the name suggests, e-paper ink displays use an electric field to drive particles, creating an ink-and-wash display. Powered by a single button battery, they maintain their display even after a power outage, making them more energy-efficient and environmentally friendly. Their display is similar to that of a paper book, making them easier on the eyes. With the rapid development of the e-paper industry, its practical applications are expanding beyond retail price tags, table signs, and name tags. They are also gaining popularity in architectural decoration, jewelry, clothing, and automotive applications. Due to the rich color palette and improved sunlight viewing experience of full-color e-paper, various decoration industries are eager to explore cross-industry integration with e-paper.

[0003] Since most decorations require curvature and softness, most module manufacturers currently use FPC as the substrate for e-paper displays. Segment code pixels are drawn on the FPC, and the surface treatment requires large-area window opening and gold immersion. After being bonded to the e-paper membrane, a segment code e-paper display is formed, and an electric field is applied to the e-paper membrane to drive the e-paper membrane.

[0004] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: However, large-area window immersion gold will cause uneven immersion gold, point loss, line loss, and immersion gold mold marks in the segment code electronic paper process, affecting the subsequent segment code electronic paper display, and the internal segment code and external terminals need to be connected through vias on the FPC. The vias are breathable, resulting in humidity imbalance inside the electronic paper, and even the external PS waterproof film is separated from the electronic paper membrane due to leakage, affecting the display. Therefore, most methods at this stage are to stick a layer of PS waterproof film on the back of the FPC to seal the conductive vias. However, the PS waterproof film has shrinkage and resilience, which will affect the curvature and softness of the FPC substrate. In addition, the existing FPC substrate does not have the anti-interference routing of the anti-static ring of the glass substrate, so external interference will cause display abnormalities in the segment code electronic paper display, resulting in color abnormalities, display back routing and other phenomena. Utility Model Content

[0005] The main purpose of the utility model is to provide a segmented electronic paper structure. By replacing the FPC surface treatment process, the contact surface damage caused by the immersion gold process is solved. By directly attaching an anti-magnetic film to the back of the FPC, it not only replaces the external PS waterproof film that needs to be attached to the back of the FPC, but also reduces the production process of the module manufacturer. The anti-magnetic film can also achieve anti-interference effect on the segmented electronic paper display, and reduces the overall thickness of the segmented electronic paper display, saving costs, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A segment code electronic paper structure includes an electronic paper display screen, which is composed of an FPC substrate, an electronic paper membrane, and a surface PS waterproof film. The FPC substrate is arranged on the back of the electronic paper membrane. The FPC substrate is composed of copper material, a surface conductive layer, a base material, an internal conductive layer, an adhesive, a cover film, and an anti-magnetic film. The side of the electronic paper membrane away from the FPC substrate is provided with a surface PS waterproof film.

[0008] Preferably, the surface PS waterproof film is a hot melt film.

[0009] Preferably, the surface conductive layer is exposed.

[0010] Preferably, the treatment process of the surface conductive layer is an OSP anti-oxidation process.

[0011] Preferably, the anti-magnetic film has a thickness of 0.015 mm.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model provides a segment code electronic paper structure, which solves the contact surface damage caused by the chemical immersion gold process to the FPC window surface by changing the FPC surface treatment process from chemical immersion gold to OSP anti-oxidation.

[0014] By directly attaching the anti-magnetic film to the back of the FPC, it not only replaces the external PS waterproof film that needs to be attached to the back of the FPC, reducing the production process of the module manufacturer, but the anti-magnetic film can also achieve anti-interference effect on the segment code electronic paper display, ensuring that the segment code electronic paper display will not cause display abnormalities due to external interference during display. In addition, replacing the external PS waterproof film with the anti-magnetic film also reduces the overall thickness of the segment code electronic paper display, saving more costs.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a segment code electronic paper structure includes an electronic paper display screen 7, which is composed of an FPC substrate 8, an electronic paper membrane 9, and a surface PS waterproof film 10. The FPC substrate 8 is arranged on the back of the electronic paper membrane 9. The FPC substrate 8 is composed of copper material, a surface conductive layer 1, a base material 2, an internal conductive layer 3, an adhesive 4, a cover film 5 and an anti-magnetic film 6. The surface PS waterproof film 10 is provided on the side of the electronic paper membrane 9 away from the FPC substrate 8.

[0022] In this embodiment, the surface PS waterproof film 10 is a hot-melt film.

[0023] In this embodiment, the surface conductive layer 1 is exposed.

[0024] In this embodiment, the surface conductive layer 1 is treated by an OSP anti-oxidation process.

[0025] In this embodiment, the thickness of the antimagnetic film 6 is 0.015 mm.

[0026] Working principle:

[0027] like Figure 1 As shown, the segment code electronic paper display 7 divides the surface copper material of the FPC according to the content to be displayed, presenting different styles of display patterns for customers. Each divided pattern is a display pixel, which can be customized according to customer needs.

[0028] like Figure 2As shown, the segmented electronic paper display 7 uses an FPC instead of a glass backplane as the substrate of the electronic paper display 7. An electronic paper film 9 is attached to the top of the FPC substrate 8. A layer of PS waterproof film 10 is attached to the top of the electronic paper film 9. The PS waterproof film 10 is a hot-melt film. That is, the PS waterproof film can be attached to the top of the electronic paper film when heated to ensure good display transmittance.

[0029] like Figure 4 As shown, the conductive layer 1 on the surface of the FPC substrate 8 is completely exposed. The surface treatment process of the conductive layer 1 uses the OSP anti-oxidation process, which replaces the traditional chemical immersion gold process. The OSP anti-oxidation process is to chemically grow an organic film on the clean bare copper surface. This film has antioxidant, heat shock resistance, and corrosion resistance, and is used to protect the copper surface from rusting in a normal environment. Moreover, this film is easily volatilized by heat during the subsequent high-temperature heating process of attaching the PS waterproof film. The OSP anti-oxidation process is simple. Compared with the chemical immersion gold process, it uses chemical organic substances instead of precious nickel and gold, thereby reducing the cost doubled caused by the large-area immersion gold of the FPC substrate 8.

[0030] like Figure 3 As shown, the back of the segment code electronic paper display 7 is the anti-magnetic film 6, which replaces the PS waterproof film used in the old process to seal the FPC substrate 8. The thickness of the anti-magnetic film 6 is 0.015mm, while the thickness of the traditional PS waterproof film is 0.256mm. The use of the anti-magnetic film 6 to replace the PS waterproof film on the back greatly reduces the overall thickness of the segment code electronic paper display 7 and increases the overall softness of the segment code display. It can be perfectly fitted to the surface of the object that the customer needs to decorate without warping or breaking. The old process requires PS waterproof film to be attached to both sides of the segment code electronic paper display 7. The electronic paper display screen 7 needs to be attached twice, and the segmented electronic paper display screen 7 needs to be heated twice. Such multiple heating will also affect the characteristics of the electronic paper film. After replacing it with the anti-magnetic film 6, the attachment process of the anti-magnetic film 6 needs to be arranged before attaching the electronic paper film. Therefore, the segmented electronic paper display screen 7 is reduced to be heated and attached once, so that the electronic paper film maintains better display characteristics and reduces the production process of the module manufacturer. The anti-magnetic film 6 needs to be connected to the ground signal line of the internal conductive layer 3 to shield external interference signals and ensure that the segmented electronic paper display screen 7 will not cause display abnormalities due to interference from external signals during the display process.
