Description

Technical Field

[0001] This invention relates to the field of display technology, specifically to an FPC backplane and an electronic paper module that improve the display effect of splicing seams. Background Technology

[0002] Electronic paper display technology represents a completely new application model for electronic paper displays. Its module structure is simple, and the manufacturing process is also straightforward. Furthermore, the backplane circuit design can be tailored to any client-designed ID pattern. Each square is connected to a single metal line, converging at the FPC lead terminal and connecting to the driver board. Given a specific driving voltage signal, each independent display unit can display different colors. Since each independent display unit does not require TFT device switching, the design is simple and can be implemented using printed circuit technology for backplane circuit design and production. Combined with Eink's latest generation of electronic paper film materials, it achieves multi-color variations, thereby attracting consumers and end-users and enabling its widespread application in the consumer goods sector.

[0003] With the continuous development of e-paper technology, especially in the application of large-size e-paper displays, splicing multiple e-paper modules into a large screen has become a common display method. However, during the splicing process of these large screens, the "seam" problem often occurs, which refers to the visual gaps or inconsistencies between adjacent modules. The existence of these seams has a significant negative impact on the overall display effect. Seams can cause discontinuities in the displayed content, especially when displaying images or videos. The gaps at the splicing points can disrupt the continuity of the image, affecting the viewing experience. Seams are particularly noticeable when displaying large areas of solid color backgrounds or complex patterns, making the transitions between colors and patterns uneven and providing users with a poor visual experience. Secondly, there may be inconsistencies in brightness or color between the display unit at the seam and the surrounding area, which may cause the details of the displayed content to be blurred or distorted at the splicing point, increasing visual interference. Summary of the Invention

[0004] This invention provides an FPC backplane and an electronic paper module for improving the bezel display effect. By implementing this invention, the bezel display effect can be improved.

[0005] An embodiment of the present invention provides an FPC back panel for improving the display effect of seams, comprising: a display area and a border around the display area;

[0006] The display area includes a plurality of pixel display units arranged in the display area and pixel display electrode lines connected to each pixel display unit in a one-to-one correspondence; wherein, the distance between two adjacent pixel display units is consistent with the width of the seam formed when two electronic paper modules are spliced ​​together; the pixel display electrode lines are used to control the display state of the pixel display units;

[0007] The display area also includes a background display unit and a background color electrode line connected to the background display unit; the background color electrode line is used to control the background display unit to display a background color that is consistent with the border color.

[0008] As a preferred embodiment of the present invention, an FPC backplate for improving the splicing effect further includes: FPC lead wire ends;

[0009] The FPC lead ends are connected to the display electrode lines and background color electrode lines of each pixel, and are connected to the external driver board;

[0010] The FPC lead terminal is used to receive the pixel display driving signal sent by the external driving board, and send the pixel display driving signal to the corresponding pixel display unit through the pixel display electrode line, so that the corresponding pixel display unit displays the corresponding color according to the color information carried in the display driving signal;

[0011] The FPC lead terminal is also used to receive the background display drive signal sent by the external drive board, and send the background display drive signal to the background display unit through the background color electrode line so that the background display unit displays a color that matches the border color.

[0012] As a preferred embodiment of the present invention, the pixel display unit is a square with rounded corners.

[0013] As a preferred embodiment of the present invention, the border color is white or black.

[0014] As a preferred embodiment of the present invention, the pixel display units are arranged in a 9*7 grid array within the display area.

[0015] In addition, another aspect of the present invention provides an electronic paper module, including an FPC backplate for improving the splicing effect and an electronic paper film; the electronic paper film is disposed above the FPC backplate.

[0016] As a preferred embodiment of the present invention, an electronic paper module further includes: an upper waterproof film and a lower waterproof film; the upper waterproof film is attached to the top of the electronic paper film; and the lower waterproof film is attached to the bottom of the FPC backplate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides an FPC backplane and an electronic paper module to improve the display effect of seams. The FPC backplane includes: a display area and a border around the display area; the display area includes a plurality of pixel display units arranged in the display area and pixel display electrode lines connected to each pixel display unit; wherein the distance between two adjacent pixel display units is consistent with the width of the seam formed when two electronic paper modules are spliced; the pixel display electrode lines are used to control the display state of the pixel display units; the display area also includes a background display unit and a background color electrode line connected to the background display unit; the background color electrode line is used to control the background display unit to display a background color consistent with the border color. By adjusting the distance between adjacent pixel display units to be equal to the width of the seam, it is ensured that the seam area maintains a consistent background width with adjacent modules during splicing; by setting the background display unit color to be consistent with the border color, the background color and the border are visually integrated, further weakening the presence of the seam. Meanwhile, the background display unit and each pixel display unit are controlled by individual electrode lines, ensuring that each unit can operate independently and perform its specific function. By implementing this invention, the problem of interference from seams on the display effect can be solved, thereby optimizing the overall display effect of the splicing screen on a larger scale.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0030] like Figure 1 , Figure 2 as well as Figure 8 As shown, an embodiment of the present invention provides an FPC back panel 11 for improving the splicing effect, including: a display area 1 and a frame 2 around the display area 1;

[0031] The display area 1 includes a plurality of pixel display units 3 arranged in the display area 1 and pixel display electrode lines 4 connected one-to-one with the pixel display units 3; wherein, the distance between two adjacent pixel display units 3 is consistent with the width of the seam 8 formed by splicing two electronic paper modules; the pixel display electrode lines 4 are used to control the display state of the pixel display units 3.

[0032] The display area 1 also includes a background display unit 5 and a background color electrode line 6 connected to the background display unit 5; the background color electrode line 6 is used to control the background display unit 5 to display a background color that is consistent with the color of the border 2.

[0033] It should be noted that the background display unit 5 is the area formed within the display area 1 excluding the pixel display units 3; for example... Figure 2 As shown, the seam 8 is the area formed by the two borders when two electronic paper modules are spliced ​​together.

[0034] Understandably, designing the distance between two adjacent pixel display units 3 to be equal to the width of the seam 8 helps maintain visual consistency in the splicing area when multiple e-paper modules are spliced ​​together. When multiple e-paper modules are spliced ​​into a large screen, the displayed content at the splicing point often exhibits discontinuity or inconsistency; especially when the displayed content spans the seam 8, inconsistencies in color, differences in brightness, or a sense of visual fragmentation may occur. By ensuring that the distance between adjacent pixel display units 3 is equal to the width of the seam 8, the shape, position, and display effect of each pixel display unit 3 can be made more consistent, reducing visual interference caused by differences in seam spacing.

[0035] Furthermore, the background color electrode line 6 controls the color of the background display unit 5, ensuring that the background color matches the border color. This prevents noticeable color breaks at the splicing points when electronic paper modules are assembled. The seam 8 is often the most visually sensitive part of a spliced ​​screen. If the background color at the seam 8 is inconsistent with the surrounding area, it can easily cause a visual discontinuity or unnatural transition. By ensuring that the color of the background display unit 5 matches the border color, the transition at the splicing point is smoother, avoiding visual abruptness and improving the consistency and continuity of the display effect.

[0036] It is understandable that the display effect of splicing together electronic paper modules including the FPC backplane is as follows: Figure 2 As shown, compared to Figure 3 The original design used two electronic modules to splice together for display effect. The design of this invention optimizes the overall display effect of the splicing screen.

[0037] In a preferred embodiment, an FPC backplate 11 for improving the seam display effect further includes: an FPC lead end 7;

[0038] The FPC lead end 7 is connected to the display electrode line 4 of each pixel and the background color electrode line 6, and is connected to the external driving board;

[0039] The FPC lead terminal 7 is used to receive the pixel display driving signal sent by the external driving board, and send the pixel display driving signal to the corresponding pixel display unit 3 through the pixel display electrode line 4, so that the corresponding pixel display unit 3 displays the corresponding color according to the color information carried in the display driving signal;

[0040] The FPC lead terminal 7 is also used to receive the background display drive signal sent by the external drive board, and send the background display drive signal to the background display unit 5 through the background color electrode line 6, so that the background display unit 5 displays a color that is consistent with the color of the border 2.

[0041] Understandably, by transmitting the driving signal to the background display unit 5 via the background color electrode line 6, the background color can be completely separated from and independently changed by the color of the pixel display unit 3. Traditional display devices often tightly integrate the control of the pixel display unit 3 and the background color, which may lead to color confusion and inconsistency between the background color and the pixel display content, affecting the display effect. However, this design independently controls the background color through the background display unit 5, which can precisely adjust the background color, ensuring that the color of the displayed content is accurate and unaffected by the background color, thus improving the overall visual effect.

[0042] Furthermore, the background color can be independently controlled via the background color electrode, reducing reliance on the pixel display electrode line 4. This allows the control of the pixel display unit 3 to focus more on the displayed content itself, preventing changes in the background color from affecting the performance and response speed of the pixel display unit 3. This design effectively improves the operational stability and response speed of the pixel display unit 3, while simplifying circuit design and manufacturing processes, and enhancing the product's manufacturability and maintainability.

[0043] like Figure 4 As shown, in a preferred embodiment, the pixel display unit 3 is a square with rounded corners.

[0044] It is understandable that, such as Figure 5 As shown, designing each pixel display unit 3 as a square with rounded corners helps to improve the "jagged" effect commonly seen in font display. Specifically, by designing square pixel display units with rounded corners based on the original rectangular display units, the edges of each pixel display unit 3 become smoother, thus avoiding visual breaks caused by sharp angles and lines, and reducing the jaggedness of the font. (Comparison) Figure 6 The original design of the "K" pattern displayed a noticeably jagged edge. However, with the adoption of a rounded design, the pattern appears more rounded and soft, with smoother edge transitions, reducing visual abruptness and improving the display's delicacy.

[0045] It is understandable that the display effect of splicing together electronic paper modules with FPC backplanes containing square pixel display units with rounded corners is as follows: Figure 7 As shown, it can effectively improve the "jagged edges" phenomenon commonly seen in font display and significantly enhance the display effect.

[0046] In a preferred embodiment, improving the "jagged" effect of displayed fonts is not limited to a square design with rounded corners; other curved shapes can achieve similar results. For example, designing the pixel display unit 3 as a circle, ellipse, or other curved contour shape can also effectively eliminate the jagged edges produced when displaying fonts. These designs share the characteristic of softer edges, resulting in a smoother and more natural display of text and images, avoiding visual discomfort caused by the sharp edges of the pixel display unit 3. These optimized designs, especially in splicing screen applications, can significantly improve display performance.

[0047] In a preferred embodiment, the border 2 is white or black.

[0048] It should be noted that the design of the frame 2 of the FPC back panel 11 generally uses black and white, which can effectively improve the display effect and meet multiple needs of production and design. For manufacturers, using black and white as the color of the frame 2 of the FPC back panel 11 can not only improve production efficiency, but also ensure the consistency of product quality.

[0049] Optionally, the pixel display units 3 are arranged in a 9*7 grid within the display area 1.

[0050] Understandably, a 9×7 grid array arrangement offers good structural stability. The uniform arrangement of pixel units within display area 1 ensures the balance of the entire display area, avoiding inconsistencies or uneven brightness caused by uneven arrangement. This results in a more uniform distribution of brightness and color across the display area, improving the overall consistency of the display effect. Furthermore, the grid array design makes the manufacturing process of the electronic paper module easier to control and optimize. The orderly arrangement of pixel display units 3 simplifies calibration and debugging during production, reducing potential errors and deviations, and improving production efficiency and product consistency. This is of great significance for large-scale production and improving production stability.

[0051] In addition, such as Figure 8 As shown, the present invention also provides an electronic paper module, including the aforementioned FPC backplate 11 for improving the bezel display effect and an electronic paper film 10; the electronic paper film is disposed above the FPC backplate 11. The electronic paper module has all the beneficial effects of the aforementioned FPC backplate 11 for improving the bezel display effect, which will not be described in detail here.

[0052] In a preferred embodiment, an electronic paper module further includes: an upper waterproof film 9 and a lower waterproof film 12; the upper waterproof film 9 is attached above the electronic paper film 10; and the lower waterproof film 12 is attached below the FPC backplate 11.

[0053] Understandably, the addition of the upper waterproof membrane 9 and the lower waterproof membrane 12 not only improves the waterproof performance of the electronic paper module and enhances its resistance to moisture and environmental impact, but also improves the physical durability of the module and extends its service life.

[0054] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
