[0027] The above and / or additional aspects and advantages of the present application will become apparent and easy to understand from the description of the embodiments in conjunction with the following drawings, in which:

[0028] Figure 1 is a top view of the electronic paper provided by an embodiment of the present application;

[0029] Figure 2 is a cross-sectional schematic diagram of the electronic paper provided by an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0031] The electronic paper and display device provided by an embodiment of the present application will be described below with reference to the drawings.

[0032] Figure 1 is a structural schematic diagram of the electronic paper provided by an embodiment of the present application.

[0033] As Figure 1 shown, the electronic paper provided by an embodiment of the present application includes a display area 10 and a non-display area located outside the display area 10. For example, the non-display area can be arranged around the periphery of the display area 10. The display area 10 can include an effective display area AA and a border display area BK. The border display area BK can be arranged around the effective display area AA. The effective display area AA is the area in the electronic paper that mainly displays image content, and the border display area BK displays corresponding colors according to requirements. The non-display area includes a conductive adhesive area 20, and the conductive adhesive area 20 is located on one side of the display area 10 along the first direction X.

[0034] The electronic paper includes an array substrate 1, an electronic paper film 2, a protective layer 3, and a driving component 4.

[0035] The array substrate 1 includes a plurality of thin film transistors and a pixel array. The plurality of thin film transistors can form a driving circuit for the pixel array. The pixel array includes a plurality of pixel electrodes, and the driving circuit can be used to control the voltage of each pixel electrode. The array substrate 1 further includes a common electrode lead located in the conductive adhesive region 20 for providing a common electrode Vcom signal.

[0036] Combined Figure 2 As shown, the electronic paper film 2 is located on one side of the array substrate 1 in the thickness direction Y, and the thickness direction Y is perpendicular to the first direction X. The electronic paper film 2 covers the display area 10 and the conductive adhesive region 20. Since the conductive adhesive region 20 is located on one side of the display area 10 along the first direction X and the area of the conductive adhesive region 20 is small (the length of the conductive adhesive region 20 along the second direction Z is less than the length of the display area 10 along the second direction Z, and the second direction Z is perpendicular to the thickness direction Y and the first direction X respectively), the electronic paper film 2 has a special-shaped structure. Among them, the electronic paper film 2 can be an EPL (E-Paper Film Layer).

[0037] The electronic paper film 2 can include a microcapsule / microcup layer 21 and a common electrode layer 22. The microcapsule / microcup layer 21 is located between the array substrate 1 and the common electrode layer 22. The microcapsule / microcup layer 21 covers the display area 10, and the common electrode layer 22 covers the display area 10. At the same time, voltages are applied to the common electrode layer 22 and the pixel electrodes in the array substrate 1 to generate a vertical electric field between the common electrode layer 22 and the pixel electrodes in the array substrate 1 to drive the electrophoretic particles in the electronic paper film 2 to move, thereby realizing the corresponding image display. The common electrode layer 22 also covers the conductive adhesive region 20, and the common electrode layer 22 is connected to the common electrode lead located in the conductive adhesive region 20 in the array substrate 1 so that the array substrate 1 provides a Vcom signal to the common electrode layer 22. Among them, the common electrode layer 22 can include ITO, etc.

[0038] In some embodiments, the electronic paper film 2 can further include a substrate (not shown in the figure), and the substrate is located on the side of the common electrode layer 22 facing away from the array substrate 1. The substrate can be a transparent upper carrier of the electronic paper film 2. Among them, the substrate can include a PET film.

[0039] The protective layer 3 is located on the side of the electronic paper film 2 facing away from the array substrate 1. The protective layer 3 covers the electronic paper film 2 to prevent the electronic paper film 2 from being scratched and prevent water vapor from entering and corroding the electronic paper film 2. Among them, the protective layer 3 can be a PS (Protective Sheet).

[0040] Since the electronic paper film 2 has an irregular shape and the protective layer 3 covers the electronic paper film 2, the protective layer 3 also has an irregular shape. The protective layer 3 includes a main body portion 31 and a convex portion 32, and the convex portion 32 is connected to one side of the main body portion 31 along the first direction X. The main body portion 31 covers the electronic paper film 2 in the display area 10, and the convex portion 32 covers the electronic paper film 2 in the conductive adhesive area 20. The length of the main body portion 31 along the second direction Z is greater than the length of the convex portion 32 along the second direction Z. Wherein, the cross-section of the main body portion 31 along the second direction Z can be rectangular, and the cross-section of the convex portion 32 along the second direction Z can be rectangular.

[0041] The driving component 4 is bonded to one side of the array substrate 1 in the thickness direction Y. The driving component 4 and the protective layer 3 are located on the same side of the array substrate 1. The driving component 4 overlaps with the main body portion 31 of the protective layer 3 along the first direction X, and the driving component 4 has no overlap with the main body portion 31 along the second direction Z. The driving component 4 overlaps with the convex portion 32 of the protective layer 3 along the second direction Z, and the driving component 4 has no overlap with the convex portion 32 along the first direction X.

[0042] In the related art, the driving component is designed to be centered, resulting in partial overlap between the driving component and the convex portion in the protective layer along the first direction. And a certain distance needs to be maintained between the driving component and the protective layer to avoid affecting the coating effect of the protective layer when the driving component is reworked, so that there is a certain distance between the driving component and the convex portion along the first direction. And both the driving component and the convex portion are located in the non-display area, resulting in a larger width of the non-display area along the first direction, that is, the border (such as the lower border) of the electronic paper along the first direction is wider and the utilization rate is lower.

[0043] In this embodiment, since the length of the main body portion 31 along the second direction Z is greater than the length of the convex portion 32 along the second direction Z, there is an idle area on the side of the convex portion 32 along the second direction Z. The driving component 4 is arranged in this idle area, so that the driving component 4 overlaps with the convex portion 32 along the second direction Z, and the driving component 4 has no overlap with the convex portion 32 along the first direction X. The driving component 4 does not need to be centered, and thus does not need to maintain a certain distance from the convex portion 32 along the first direction X. Thereby, the driving component 4 is arranged close to the display area 10 (such as moving the driving component 4 upward), reducing the width of the non-display area along the first direction X, thereby reducing the size of the array substrate 1, reducing the border (such as the lower border) of the electronic paper along the first direction X, and improving the border utilization rate. The reduction of the size of the array substrate 1 enables the total cutting number to be increased by 2.4% and the utilization rate to be increased by 1.06%, thereby reducing the cost.

[0044] In some embodiments, the driving assembly 4 is offset relative to the central axis of the array substrate 1 along the first direction X toward the second direction Z. The central axis of the driving assembly 4 along the first direction X does not coincide with the central axis of the array substrate 1 along the first direction X. The central axis of the driving assembly 4 along the first direction X is located on a side of the central axis of the array substrate 1 along the first direction X away from the protrusion 32, such that the driving assembly 4 is offset toward the second direction away from the protrusion 32.

[0045] In the related art, the driving component is centrally arranged, that is, the central axis of the driving component along the first direction coincides with the central axis of the array substrate along the first direction, so that the driving component overlaps with the raised portion along the first direction, that is, at least part of the structure of the driving component is located on the side of the raised portion away from the main body, resulting in a wider border of the electronic paper along the first direction (such as the lower border) and a lower utilization rate.

[0046] In this embodiment, the driving component 4 is offset in the second direction Z to avoid the raised portion 32, so that the driving component 4 and the raised portion 32 do not overlap along the first direction X. The driving component 4 can be moved upward along the first direction X to be closer to the display area 10, thereby reducing the border of the electronic paper along the first direction (such as the lower border) and improving the utilization rate of the border.

[0047] In some embodiments, the driving component 4 and the raised portion 32 at least partially overlap along the second direction Z. The driving component 4 and the raised portion 32 may partially overlap along the second direction Z, but the driving component 4 is disposed closer to the display area 10 than in the related art. The driving component 4 and the raised portion 32 may also completely overlap.

[0048] In some embodiments, the side of the driving component 4 facing away from the main portion 31 does not extend beyond the side of the protrusion 32 facing away from the main portion 31. Furthermore, the distance between the surface of the driving component 4 facing away from the main portion 31 and the display area 10 along the first direction X is less than or equal to the distance between the surface of the protrusion 32 facing away from the main portion 31 and the display area 10 along the first direction X.

[0049] The width of the driving component 4 along the first direction X is smaller than the width of the protrusion 32 along the first direction X, so that the driving component 4 can be located on the side of the protrusion 32 along the second direction Z, and the side of the driving component 4 facing away from the main body 31 does not exceed the side of the protrusion 32 facing away from the main body 31, so as to minimize the border of the electronic paper along the first direction X (such as the lower border).

[0050] In some embodiments, the side of the driving component 4 facing away from the protruding portion 32 does not exceed the same side of the main body portion 31. The driving component 4 and the protruding portion 32 are arranged side by side on one side of the main body portion 31 along the first direction X. The side of the driving component 4 facing away from the protruding portion 32 (the side of the driving component 4 along the second direction Z, such as the right side of the driving component 4) does not exceed the same side of the main body portion 31 along the second direction Z (such as the right side of the main body portion 31), that is, the distance between the right side surface of the driving component 4 and the protruding portion 32 along the second direction Z is less than the distance between the right side surface of the main body portion 31 and the protruding portion 32 along the second direction Z.

[0051] The length of the main body portion 31 along the second direction Z is greater than the sum of the length of the protruding portion 32 along the second direction Z and the length of the driving component 4 along the second direction Z, so that the driving component 4 can be located on the side of the protruding portion 32 along the second direction Z, and the side of the driving component 4 facing away from the protruding portion 32 does not exceed the same side of the main body portion 31, avoiding increasing the border of the electronic paper along the second direction Z (such as the right border).

[0052] In some embodiments, the conductive adhesive area 20 is arranged close to the edge of the display area 10 along the second direction Z, and the protruding portion 32 is arranged close to the edge of the main body portion 31 along the second direction Z and covers the conductive adhesive area 20. The surface of the protruding portion 32 on the side facing away from the driving component 4 (such as the left side surface of the protruding portion 32) may be flush with the same side surface of the main body portion 31 (such as the left side surface of the main body portion 31).

[0053] The driving component 4 is arranged close to the protruding portion 32. When the driving component 4 and the protruding portion 32 are kept at a certain distance along the second direction Z, the driving component 4 is arranged as close as possible to the protruding portion 32 to avoid too large a deviation distance of the driving component 4 along the second direction Z, which affects the setting of other devices and traces.

[0054] In some embodiments, the driving component 4 includes a flexible circuit board 41, and the flexible circuit board 41 is bonded to one side of the array substrate 1 in the thickness direction Y. The flexible circuit board 41 overlaps with the main body portion 31 along the first direction X, and the side of the flexible circuit board 41 facing away from the protruding portion 32 (such as the right side of the flexible circuit board 41) does not exceed the same side of the main body portion 31 (such as the right side of the main body portion 31). The flexible circuit board 41 overlaps with the protruding portion 32 along the second direction Z. The flexible circuit board 41 and the protruding portion 32 may partially overlap along the second direction Z, and the flexible circuit board 41 and the protruding portion 32 may also completely overlap, that is, the side of the flexible circuit board 41 facing away from the main body portion 31 does not exceed the side of the protruding portion 32 facing away from the main body portion 31. Among them, the flexible circuit board 41 may be an FPC.

[0055] In the related art, the flexible circuit board 41 and the protruding portion 32 overlap along the first direction X, and the flexible circuit board 41 and the protruding portion 32 do not overlap along the second direction Z. That is, the flexible circuit board 41 is located on the side of the protruding portion 32 away from the main body portion 31, and the flexible circuit board 41 and the protruding portion 32 maintain a certain distance along the first direction X, resulting in a wider border (such as the lower border) of the electronic paper along the first direction X.

[0056] In this embodiment, the flexible circuit board 41 and the protruding portion 32 overlap along the second direction Z, and the flexible circuit board 41 and the protruding portion 32 do not overlap along the first direction X. That is, the flexible circuit board 41 is located on the side of the protruding portion 32 along the second direction Z. Compared with the related art, the flexible circuit board 41 is disposed closer to the display area 10, thereby reducing the border (such as the lower border) of the electronic paper along the first direction X.

[0057] In some embodiments, the driving assembly 4 further includes a driving chip 42. The driving chip 42 is bonded to one side of the array substrate 1 in the thickness direction Y, and the driving chip 42 is connected to the flexible circuit board 41. The flexible circuit board 41 is configured to transmit power signals, control commands, image data, etc. of an external circuit to the driving chip 42. The driving chip 42 is configured to process control commands and graphic data and then convert them into a control timing of the array substrate 1 to implement image display.

[0058] The driving chip 42 is located between the flexible circuit board 41 and the main body portion 31, and the driving chip 42 is spaced apart from the flexible circuit board 41 and the main body portion 31.

[0059] The driving chip 42 and the flexible circuit board 41 may be centered and aligned. The length of the driving chip 42 along the second direction Z is less than the length of the flexible circuit board 41 along the second direction Z. The driving chip 42 is located between the flexible circuit board 41 and the main body portion 31, such that the driving chip 42 and the protruding portion 32 completely overlap along the second direction Z, and the driving chip 42 and the main body portion 31 completely overlap.

[0060] In some embodiments, an EC glue (epoxy resin type thermosetting glue) is provided on the peripheral side of the electronic paper film 2 to prevent water vapor from infiltrating into the electronic ink film (FPL) from all around.

[0061] It should be noted that the water content of the electronic paper film 2 needs to be maintained stable. The change in the water content will directly affect the display effect of the electronic paper. Therefore, in the production process of the electronic paper display panel, a material is needed to seal the periphery of the electronic ink film to prevent water vapor in the microcapsules from entering or leaking. The EC glue is a two-component epoxy resin glue, which has good adhesion, weather resistance and heat resistance. Using the EC glue as the encapsulation material of the electronic paper film 2 can effectively prevent the entry or loss of water vapor.

[0062] To avoid interference between the EC glue and the ACF glue used for bonding the driving component 4, and to avoid affecting the coating effect of the protective layer 3 when the driving component 4 is reworked, the driving component 4 and the protective layer 3 are arranged at intervals.

[0063] In some embodiments, the driving component 4 and the main body portion 31 are arranged at intervals in the first direction X, that is, the driving chip 42 and the main body portion 31 are arranged at intervals in the first direction X. The distance between the driving component 4 and the main body portion 31 in the first direction X is greater than the first distance. In some embodiments, the first distance is not less than 2.1 mm.

[0064] In some embodiments, the driving component 41 and the protruding portion 32 are arranged at intervals in the second direction Z, that is, the flexible circuit board 41 and the protruding portion 32 are arranged at intervals in the second direction Z. The distance between the driving component 41 and the protruding portion 32 in the second direction Z is greater than the second distance. In some embodiments, the second distance is not less than 2.2 mm.

[0065] In some embodiments, the electronic paper further includes a conductive glue 5. The conductive glue 5 is located in the conductive glue area 20, and the conductive glue 5 is connected between the array substrate 1 and the electronic paper film 2. The conductive glue 5 can be connected between the common electrode lead in the array substrate 1 and the common electrode layer 22 in the electronic paper film 2.

[0066] The array substrate 1 provides a Vcom signal to the common electrode layer 22 in the electronic paper film 2 through the common electrode lead and the conductive glue 5 to provide a voltage to the common electrode layer 22. At the same time, a voltage is provided to the pixel electrode in the array substrate 1, so that a vertical electric field is generated between the common electrode layer 22 and the pixel electrode in the array substrate 1 to drive the electrophoretic particles in the electronic paper film 2 to move, thereby realizing the corresponding image display.

[0067] In some embodiments, the electronic paper may further include a scanning line and a data line. The scanning line is used to transmit a gate scanning signal to control the on / off of the thin film transistor in the array substrate 1. The data line is used to transmit a data signal. The scanning line and the data line are respectively connected to the driving chip 42, and the driving chip 42 provides a gate scanning signal to the scanning line and a data signal to the data line.

[0068] According to the electronic paper provided by the embodiment of the present application, the driving component 4 and the main body portion 31 of the protective layer 3 covering the display area 10 overlap in the first direction X, the driving component 4 and the protruding portion 32 of the protective layer 3 covering the conductive glue area 20 overlap in the second direction Z, and the driving component 4 and the protruding portion 32 have no overlap in the first direction X, that is, the driving component 4 is located in the idle area on one side of the protruding portion 32 in the second direction Z, so that the driving component 4 is arranged closer to the display area 10, without the need for a centered design, reducing the border of the electronic paper, improving the border utilization rate, and reducing the size of the array substrate 1, increasing the total cutting number, and reducing the cost.

[0069] Correspondingly, an embodiment of the present application further provides a display device.

[0070] The display device provided by the embodiment of the present application includes the electronic paper in the above embodiment, which will not be elaborated here in detail.

[0071] The display device provided by the embodiment of the present application can be applied to products or components with display functions such as mobile phones, watches, e-paper readers, billboards, and bulletin boards.

[0072] According to the display device provided by the embodiment of the present application, the driving component in the electronic paper intersects with the main body portion covering the display area in the protective layer along the first direction, the driving component intersects with the convex portion covering the conductive adhesive area in the protective layer along the second direction, and the driving component has no overlap with the convex portion along the first direction, that is, the driving component is located in the idle area on one side of the convex portion along the second direction, so that the driving component is closer to the display area, without the need for a centered design, reducing the border of the electronic paper, improving the border utilization rate, further reducing the border of the display device, and reducing the size of the array substrate, increasing the total cutting number, and reducing the cost.
