[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Electronic paper device, including:

[0007] Electronic paper module;

[0008] An auxiliary mechanism includes a cover plate assembly and a fluorescent element. The cover plate assembly is disposed on the electronic paper module, and the fluorescent element is disposed on an area of ​​the cover plate assembly that can receive ambient light.

The adhesive component is configured as liquid adhesive, and the fluorescent component is configured as a fluorescent agent and mixed in the liquid adhesive. The auxiliary cover plate is bonded to the electronic paper module by the liquid adhesive.

[0014] As a further technical solution, the cover plate assembly also includes a barrier member, which is disposed on the end face of the auxiliary cover plate near the electronic paper module. The barrier member extends in a ring shape along the circumference of the auxiliary cover plate and cooperates with the auxiliary cover plate to form a receiving cavity for accommodating the liquid adhesive.

[0030] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0031] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0033] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0034] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0035] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0036] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0037] Combination Figures 1 to 6 As shown, the electronic paper device provided in this embodiment enables the electronic paper module 100 to display normally in low light or dark environments, and has low production costs and strong applicability. Specifically, the electronic paper device includes an electronic paper module 100 and an auxiliary mechanism 200; the auxiliary mechanism 200 includes a cover plate assembly 210 and a fluorescent element. The cover plate assembly 210 is disposed on the electronic paper module 100, and the fluorescent element is disposed on an area of ​​the cover plate assembly 210 that can receive ambient light. The fluorescent element can emit fluorescence in low light environments.

[0038] Because a cover plate assembly 210 is provided on the electronic paper module 100, and a fluorescent element is provided on the cover plate assembly 210, during the use of the electronic paper device, the fluorescent element absorbs and stores light energy in a lit environment. When the electronic paper device is in a low-light or dark environment, the fluorescent element excites visible light in the form of fluorescence, enabling the electronic paper module 100 to display normally. Throughout the process, the cover plate assembly 210 with the fluorescent element enables the electronic paper device to display normally in low-light or dark environments without modifying the electronic ink. Therefore, it is convenient to operate and reduces production costs. Furthermore, the cover plate assembly 210 with the fluorescent element can be used in electronic paper modules 100 that have already been produced or are yet to be produced, thus having a wide range of applications. The electronic paper module 100 is not the focus of this solution and can be designed with reference to existing technologies; no specific limitations are made here.

[0039] Taking the example where both the auxiliary cover plate 211 and the electronic paper module 100 are rectangular, this embodiment provides three implementation methods for setting the fluorescent element: the fluorescent element is set on the auxiliary cover plate 211, the fluorescent element is set on the adhesive component 212, and the fluorescent element is set on the water-blocking film 214; the details are as follows:

[0040] Example 1

[0041] Preferably, the cover plate assembly 210 includes an auxiliary cover plate 211 and an adhesive component 212. The auxiliary cover plate 211 is bonded to the electronic paper module 100 via the adhesive component 212, and the fluorescent component is disposed on the auxiliary cover plate 211. This configuration ensures that the electronic paper module 100 can display normally in low light or dark environments while further reducing the processing difficulty.

[0042] Specifically, in combination Figure 1 As shown, the fluorescent element is a fluorescent sticker 220, which is affixed to the end face of the auxiliary cover 211 near the electronic paper module 100. This arrangement reduces wear on the fluorescent sticker 220, thereby extending its service life. In some other embodiments, the fluorescent sticker 220 is disposed on the end face of the auxiliary cover 211 opposite to the electronic paper module 100, or the fluorescent sticker 220 is disposed on the side wall of the auxiliary cover 211.

[0043] Combination Figure 1 and Figure 2 As shown, along the thickness direction of the auxiliary cover plate 211, the cross-sectional area of ​​the auxiliary cover plate 211 is larger than the cross-sectional area of ​​the electronic paper module 100. The fluorescent sticker 220 is disposed near the edge of the auxiliary cover plate 211 and extends in a ring shape along the circumference of the auxiliary cover plate 211. This arrangement ensures that the electronic paper module 100 can display normally in low light or dark environments while preventing the fluorescent sticker 220 from obscuring the electronic paper module 100, thus ensuring the usability of the electronic paper module 100. In some other embodiments, the fluorescent sticker 220 may be affixed only to one side of the auxiliary cover plate 211, such as... Figure 3 As shown; or the fluorescent sticker 220 is affixed to two or three side walls of the auxiliary cover plate 211.

[0044] Preferably, the auxiliary mechanism 200 further includes a protective component 230, which is disposed on the auxiliary cover plate 211 corresponding to the fluorescent sticker 220. (Combined) Figure 1 As shown, the protective component 230 can be made of transparent paper or transparent plastic, and then adhered to the auxiliary cover plate 211 with the aid of an external adhesive; the protective component 230 can also be made directly as transparent tape and adhered to the auxiliary cover plate 211 in correspondence with the fluorescent sticker 220. By setting the protective component 230, the protective effect on the fluorescent sticker 220 is further improved, the wear rate of the fluorescent sticker 220 is slowed down, thereby extending the service life of the auxiliary mechanism 200 and the electronic paper device.

[0045] Example 2

[0046] Combination Figure 4As shown, the cover assembly 210 includes an auxiliary cover 211 and an adhesive 212. The adhesive 212 is a liquid adhesive, and the fluorescent component is a fluorescent agent mixed in the liquid adhesive. The auxiliary cover 211 is bonded to the electronic paper module 100 by the liquid adhesive. After the auxiliary cover 211 is bonded to the electronic paper module 100 by the liquid adhesive, the fluorescent agent mixed in the liquid adhesive is evenly spread between the auxiliary cover 211 and the electronic paper module 100. In low light or dark environments, fluorescence is emitted from directly above the electronic paper module 100 so that the electronic paper module 100 can display normally. Alternatively, phosphor powder can be mixed into the liquid adhesive; or, phosphor powder and fluorescent agent can be mixed simultaneously in the liquid adhesive. The specific type of liquid adhesive is selected according to the actual situation and is not specifically limited here.

[0047] To improve the ease of applying liquid adhesive to the lower end face of the auxiliary cover plate 211 or the electronic paper module 100, the cover plate assembly 210 further includes a barrier member 213. The barrier member 213 is disposed on the end face of the auxiliary cover plate 211 near the electronic paper module 100. The barrier member 213 extends circumferentially along the auxiliary cover plate 211 in a ring shape and cooperates with the auxiliary cover plate 211 to form a receiving cavity for accommodating the liquid adhesive. When the auxiliary cover plate 211 is bonded to the electronic paper module 100, the liquid adhesive is poured into the receiving cavity to ensure the bonding effect and improve the ease of operation and the cleanliness of the electronic paper device.

[0048] Alternatively, the cover assembly 210 includes an auxiliary cover 211 and an adhesive component 212. The adhesive component 212 is configured as a frame, and the fluorescent element is disposed within the frame. The auxiliary cover 211 is adhered to the electronic paper module 100 via the frame. The fluorescent element can be a fluorescent agent or phosphor, and the frame can be a ring-shaped frame, an elliptical frame, a rectangular frame, or a polygonal frame. Furthermore, to improve the strength and stability of the adhesion between the auxiliary cover 211 and the electronic paper module 100, multiple frames can be provided between the auxiliary cover 211 and the electronic paper module 100. Figure 5 As shown, in this embodiment, a rectangular frame is provided between the auxiliary cover plate 211 and the electronic paper module 100. In low light or dark environments, fluorescence is emitted from all sides of the electronic paper module 100 so that the electronic paper module 100 can be displayed normally. Alternatively, depending on actual needs, fluorescent elements can be provided only on one or more sidewalls of the frame.

[0049] Example 3

[0050] Combination Figure 6As shown, the cover assembly 210 also includes a water-blocking film 214, which is disposed on the electronic paper module 100. The auxiliary cover 211 is bonded to the water-blocking film 214 via an adhesive 212. By providing the water-blocking film 214 on the electronic paper module 100, damage to the electronic paper module 100 from water and oxygen is reduced, thereby extending the service life of the electronic paper module 100. A fluorescent element is disposed on the water-blocking film 214. Through its own characteristics, it provides a light source for the electronic paper module 100 in low-light or dark environments, enabling the electronic paper module 100 to display normally. In this embodiment, the fluorescent element can be a fluorescent agent or phosphor. The fluorescent element can be disposed on the side of the water-blocking film 214 near the auxiliary cover 211, or on the side of the water-blocking film 214 near the electronic paper module 100; no specific limitation is made here.

[0051] In addition to the three embodiments mentioned above, fluorescent elements can also be provided on two of the auxiliary cover plate 211, adhesive component 212, and water-blocking membrane 214, depending on actual needs; or, fluorescent elements can be provided on all of the auxiliary cover plate 211, adhesive component 212, and water-blocking membrane 214.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
