Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a transparent display splicing screen and a method for preparing the transparent display splicing screen. Background Technology

[0002] With the development trend of displays and market demand, various new display technologies are constantly emerging. Transparent display technology is becoming increasingly common in people's lives, such as shop windows, car windows, and commercial displays. Micro-LED (MicroLight Emitting Diode) displays have characteristics such as high brightness, long lifespan, wide color gamut, high PPI (Pixels Per Inch), seamless splicing, and high adaptability. Among them, Micro-LED transparent displays have a greater advantage in transparent screens.

[0003] Another advantage of Micro-LED display technology is that screens of infinite size can be assembled by splicing. However, traditional Micro-LED transparent display splicing screens have obvious splicing seams, which cause the displayed image to appear fragmented. Summary of the Invention

[0004] Therefore, it is necessary to provide a transparent display splicing screen and its preparation method to address the issue that the obvious splicing seams in traditional Micro-LED transparent display splicing screens cause a sense of disjointedness in the displayed image.

[0005] To achieve the above objectives, this application provides a transparent display splicing screen, comprising:

[0006] Multiple transparent display screens are spliced ​​together with their graphic sidewalls. The seams formed by the splicing of the graphic sidewalls are used to change the amount of ambient light transmitted through them.

[0007] In one embodiment, a graphical structure is formed on the graphical sidewall, and the graphical structure is a checkerboard structure.

[0008] Furthermore, the chessboard-like structure includes multiple black squares arranged at equal intervals along the row and column directions, with equal row spacing between multiple rows of black squares and staggered arrangement of multiple columns of black squares with equal staggered distances.

[0009] In one embodiment, a patterned structure is formed on the patterned sidewall, and the patterned structure is a honeycomb structure.

[0010] Furthermore, the honeycomb structure includes multiple black polygons arranged at equal intervals along the row and column directions, with equal row spacing between the multiple rows of black polygons and staggered arrangement of multiple columns of black polygons with equal stagger distances.

[0011] In one embodiment, a patterned structure is formed on the patterned sidewall, and the patterned structure is an equally spaced vertical strip structure.

[0012] In one embodiment, a patterned structure is formed on the patterned sidewall, and the patterned structure is a horizontal strip structure with equal spacing.

[0013] On the other hand, this application also provides a method for preparing a transparent display splicing screen, including:

[0014] Multiple substrates are provided, and display chips are transferred on each substrate to form multiple transparent display screens;

[0015] The target sidewalls of the substrate of each transparent display screen are patterned to form patterned sidewalls;

[0016] Multiple transparent display single screens are spliced ​​together using graphic sidewalls to form a transparent display splicing screen; the splicing seams formed by splicing the graphic sidewalls are used to change the amount of ambient light transmitted.

[0017] In one embodiment, patterning the target sidewalls of the substrate of each transparent display screen includes:

[0018] Patterned structures are formed on the target sidewalls of the substrate of each transparent display screen using any of the following techniques: pad printing, nanoimprinting, ink printing, or photolithography.

[0019] In one embodiment, forming a patterned structure on the target sidewall of the substrate of each transparent display screen using pad printing technology includes:

[0020] A pad printing material is provided, which includes a pattern capable of altering the amount of ambient light transmitted through the target sidewall;

[0021] Ink is applied to the pattern on the pad printing part, and the pattern on the pad printing part is transferred to the pad printing part by pressing the pad printing head;

[0022] By pressing a patterned adhesive tip onto the target sidewall of the substrate of each transparent display screen, the pattern on the adhesive tip is transferred to the target sidewall, forming a patterned structure.

[0023] In one embodiment, patterning the target sidewalls of the substrate of each transparent display screen includes:

[0024] A checkerboard structure is formed on the target sidewall of the substrate of each transparent display screen; wherein, the checkerboard structure includes multiple black squares arranged at equal intervals along the row and column directions, the row spacing between multiple rows of black squares is equal, and the black squares in multiple columns are staggered with equal stagger distances.

[0025] In one embodiment, patterning the target sidewalls of the substrate of each transparent display screen includes:

[0026] A honeycomb structure is formed on the target sidewall of the substrate of each transparent display screen; the honeycomb structure includes multiple black polygons arranged at equal intervals along the row and column directions, the row spacing between multiple rows of black polygons is equal, and the black polygons in multiple columns are staggered with equal stagger distances.

[0027] The transparent display splicing screen and its preparation method described in this application have the following beneficial effects:

[0028] The transparent display splicing screen of this application, due to the patterned sidewalls formed on each transparent display screen, can alter the amount of ambient light transmitted through the splicing seams created by the patterned sidewalls when ambient light passes through. This results in some light being absorbed while some light passes through, thereby reducing the total internal reflection phenomenon of ambient light at the splicing seams. Simultaneously, it does not completely block ambient light, ensuring that some ambient light can pass through normally. Therefore, it can darken the originally bright lines of the splicing seams without forming obvious black lines, avoiding a sense of fragmentation in the displayed image and improving the consistency and integrity of the displayed image.

[0029] The method for fabricating a transparent display splicing screen disclosed in this application involves patterning the target sidewalls of the substrate of each individual transparent display screen to form patterned sidewalls. After splicing multiple patterned sidewalls of the individual transparent display screens to form a transparent display splicing screen, the splicing seams formed by the patterned sidewalls alter the amount of transmitted ambient light when ambient light passes through. This results in some light being absorbed while some light passes through, thereby reducing total internal reflection at the splicing seams without completely blocking ambient light, ensuring that some ambient light can pass through normally. Therefore, the bright lines of the original splicing seams are darkened without forming obvious black lines, avoiding a sense of discontinuity in the displayed image and improving the consistency and integrity of the displayed image.

[0046] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate preferred embodiments of the application. However, this application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0048] It should be understood that when an element or layer is referred to as "on," "adjacent to," "connected to," or "coupled to" other elements or layers, it may be directly on, adjacent to, connected to, or coupled to other elements or layers, or there may be intervening elements or layers. Conversely, when an element is referred to as "directly on," "directly adjacent to," "directly connected to," or "directly coupled to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc., may be used to describe various elements, parts, regions, layers, doping types, and / or portions, these elements, parts, regions, layers, doping types, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, part, region, layer, doping type, or portion from another element, part, region, layer, doping type, or portion. Therefore, without departing from the teachings of this application, the first element, component, region, layer, doping type, or portion discussed below may be represented as a second element, component, region, layer, or portion; for example, the first doping type may be referred to as the second doping type, and similarly, the second doping type may be referred to as the first doping type; the first doping type and the second doping type are different doping types, for example, the first doping type may be P-type and the second doping type may be N-type, or the first doping type may be N-type and the second doping type may be P-type.

[0049] Spatial relation terms such as “below,” “under,” “below,” “under,” “above,” “above,” etc., are used herein to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as “below,” “under,” or “below” will be oriented “above” the other element or feature. Therefore, the exemplary terms “below” and “under” can include both above and below orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0050] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that when the terms “comprise” and / or “comprising” are used in this specification, the presence of the stated feature, integer, step, operation, element, and / or part is established, but the presence or addition of one or more other features, integers, steps, operations, elements, parts, and / or groups is not excluded. Meanwhile, when used herein, the term “and / or” includes any and all combinations of the associated listed items.

[0051] Embodiments of the invention are described herein with reference to cross-sectional views illustrating ideal embodiments (and intermediate structures) of this application, thus allowing for variations in the illustrated shapes due to, for example, manufacturing techniques and / or tolerances. Therefore, embodiments of this application should not be limited to the specific shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing techniques. For instance, implantation regions shown as rectangular typically have rounded or curved features at their edges and / or implantation concentration gradients, rather than a binary change from implantation regions to non-implantation regions. Similarly, the buried regions formed by implantation can result in some implantation in the region between the buried region and the surface traversed during implantation. Therefore, the regions shown in the figures are substantially schematic, and their shapes do not represent the actual shapes of regions of the device and do not limit the scope of this application.

[0052] Splicing technology refers to assembling multiple individual display screens into a single unit through processes such as alignment and frame bonding. Because these are independent screens physically joined together, the seams cannot be completely eliminated; that is, a certain distance of gap remains at the joint. Viewers in front of the spliced ​​display screen can see the seams clearly.

[0053] The main reason for the noticeable seams in transparent display video walls is the transparency of the screen itself. The refractive index of the air medium between the seams and the transparent screen medium (such as glass) is different. This difference in refractive index alters the light path as ambient light passes through the seams, causing some light to undergo total internal reflection (reflection and refraction) before entering the viewer's eye. This results in the seams appearing as bright lines. Figure 1 and Figure 2 As shown, Figure 1 This is a structural diagram of a traditional transparent display splicing screen 10. Figure 2 yes Figure 1 The cross-sectional diagram at point AA' shows that the traditional transparent display splicing screen 10 is composed of 2×2 traditional display single screens 100 spliced ​​together. When the ambient light 30 passes through the first splicing seam 101, some of the light undergoes total internal reflection (reflection and refraction) and enters the eye of the viewer 20, thus making the first splicing seam 101 a bright line. Angle of incidence Let be the reflection angle, when When the angle is greater than the critical angle, total internal reflection occurs, and = .

[0054] In traditional technology, to improve the first seam 101, it is filled with black material to reduce the color difference between the first seam 101 and the screen body. However, this process is only suitable for non-transparent display splicing screens. While filling the first seam 101 with black material eliminates the original bright stripe, it creates a more noticeable black seam, which can also cause a fragmented display. Figure 3 and Figure 4 As shown, Figure 3 This is a structural schematic diagram of the first transparent display splicing screen 11. Figure 4 yes Figure 3 The cross-sectional diagram at point AA' shows that the first transparent display splicing screen 11 is composed of 2×2 first display single screens 110 spliced ​​together. The first transparent display splicing screen 11 includes a second splicing seam 111, which is filled with black material. Because the second splicing seam 111 is filled with black material, it becomes a clearly visible long black strip. This indicates that although the total internal reflection light at the second splicing seam 111 is absorbed, other transmitted light is also absorbed simultaneously, preventing any light from penetrating into the human eye at the second splicing seam 111. Therefore, the human eye perceives this area as completely black.

[0055] Therefore, in order to solve the above problems, a method for preparing a transparent display splicing screen and a transparent display splicing screen are proposed, which can change the amount of transmitted light 30 at the splicing seam to reduce the total internal reflection phenomenon of ambient light 30 at the splicing seam.

[0056] In one exemplary embodiment, please refer to Figure 5 This application provides a method for preparing a transparent display splicing screen, comprising the following steps:

[0057] Step 502: Provide multiple substrates, and transfer display chips on each substrate to form multiple transparent display screens.

[0058] Optionally, a transparent display splicing screen is obtained by splicing multiple transparent display individual screens. Therefore, it is necessary to first form multiple transparent display individual screens, such as a Micro-LED display screen with a transparent screen body. Each transparent display individual screen corresponds to a substrate, so multiple substrates can be provided during the formation of the transparent display individual screen. The substrate refers to the substrate used to mount and drive the display chip in the transparent display individual screen. The material of the substrate can be, but is not limited to, glass, ceramic, and silicon, and the type of substrate should not limit the scope of protection of this application. A driving trace film layer is formed on the substrate. The driving trace film layer contains control circuits, driving circuits, and other lines to ensure that current and signals can be effectively transmitted to each pixel. Then, the display chip is transferred on each substrate, completing the display chip transfer process. For example, the display chip can be a Micro-LED.

[0059] Step 504: The target sidewalls of the substrate of each transparent display screen are patterned to form patterned sidewalls.

[0060] Optionally, after completing the display chip transfer process, the target sidewalls of the substrate of each transparent display panel are patterned to form patterned sidewalls. The target sidewalls refer to the sidewalls that need to be spliced ​​when assembling the transparent display panels. Patterning refers to forming a patterned structure on the target sidewalls of the substrate to obtain the patterned sidewalls. The patterned structure is a light-dark structure; when ambient light 30 shines on the patterned structure, some light is absorbed, and some light passes through, weakening the total internal reflection phenomenon of ambient light 30 at the splicing seam while preventing complete blockage, ensuring that some ambient light 30 can pass through normally. Therefore, the bright lines of the original splicing seam are darkened without forming obvious black lines.

[0061] Optionally, before patterning, a module process is completed on the substrate. This module process may include substrate cutting and substrate edge grinding. Substrate cutting refers to cutting to the required dimensions. Substrate edge grinding refers to cutting to the required dimensions.

[0062] Step 506: The graphic sidewalls of multiple transparent display single screens are spliced ​​together to form a transparent display splicing screen; the splicing seam formed by splicing the graphic sidewalls is used to change the amount of transmitted light from the ambient light 30.

[0063] Multiple transparent display panels with patterned sidewalls are spliced ​​together using a splicing process to form a transparent display splicing screen. For example, the splicing process may include alignment and frame bonding. When ambient light 30 passes through the splicing seam formed by the patterned sidewalls, the patterned sidewalls can alter the amount of transmitted light 30, thereby reducing total internal reflection at the splicing seam.

[0064] like Figure 6 The diagram shows a schematic of the structure of a transparent display splicing screen 12. The transparent display splicing screen 12 is composed of 2×2 transparent display single screens 120 spliced ​​together. The transparent display single screen 120 includes a splicing seam 121, and a patterned structure 123 is formed on the target sidewall 122 of the substrate of the transparent display single screen 120.

[0065] In the above embodiment, the target sidewall 122 of the substrate of each transparent display panel 120 is patterned to form a patterned sidewall. After splicing the patterned sidewalls of multiple transparent display panels 120 to form a transparent display splicing screen, when ambient light 30 passes through, the splicing seam formed by the patterned sidewalls can change the amount of transmitted light 30, so that some light is absorbed and some light is transmitted, thereby reducing the total internal reflection phenomenon of ambient light 30 at the splicing seam, while not completely blocking the ambient light 30, ensuring that some ambient light 30 can pass through normally. Therefore, the bright lines of the original splicing seam can be darkened without forming obvious black lines, avoiding the sense of discontinuity in the displayed image and improving the consistency and integrity of the displayed image.

[0066] In an exemplary embodiment, step 504, patterning the target sidewall 122 of the substrate of each transparent display single screen 120, includes forming a patterned structure 123 on the target sidewall 122 of the substrate of each transparent display single screen 120 by any one of pad printing technology, nanoimprint technology, ink printing technology, and photolithography technology.

[0067] Optionally, the target sidewalls 122 of the substrate of each transparent display screen 120 can be patterned using various methods. Specifically, not only can pad printing technology be used to form patterned structures 123 on the target sidewalls 122 of the substrate of each transparent display screen 120, but nanoimprint lithography, inkjet printing, or photolithography can also be used to form patterned structures 123 on the target sidewalls 122 of the substrate of each transparent display screen 120. For example, the inkjet printing technology can be IJP (Ink Jet Printing) technology.

[0068] In this embodiment, the patterning process can be implemented in various ways, achieving the effect of diverse process options and realizing flexible patterning of the substrate sidewalls.

[0069] In one optional embodiment described above, forming a patterned structure 123 on the target sidewall 122 of the substrate of each transparent display panel 120 using pad printing technology includes: providing a pad printing member, the pad printing member including a pattern capable of changing the amount of ambient light 30 transmitted at the target sidewall 122; applying ink to the pattern on the pad printing member; pressing the pad printing member with a printing head to transfer the pattern on the pad printing member to the printing head; pressing the printing head with the pattern onto the target sidewall 122 of the substrate of each transparent display panel 120 to transfer the pattern on the printing head to the target sidewall 122, thereby forming a patterned structure 123.

[0070] like Figure 7 The diagram illustrates the process of forming a patterned structure 123 on the target sidewall 122 of the substrate of each transparent display panel 120 using pad printing technology. A pad printing element 40 is provided, having a pattern that alters the amount of ambient light 30 transmitted through the target sidewall 122. This pattern is transferred at a 1:1 scale. The pattern is formed on the pad printing element 40 through both open and closed areas. For example, the pad printing element 40 can be a stencil. After the pad printing element 40 is fixed to the stage 50, ink 70 is applied to the pattern on the pad printing element 40 using an ink cup 60, specifically, the ink 70 can be applied to the non-open area of ​​the pattern. Then, a printing head 80 is used to press the pad printing element 40, transferring the pattern from the pad printing element 40 to the printing head 80. Finally, the patterned printing head 80 is used to press... Figure 6 The pattern on the substrate 124 of each transparent display panel 120 is transferred to the target sidewall 122 by the adhesive applicator 80 to form a patterned structure 123. Optionally, black photoresist can also be coated on the pattern of the pad printing piece 40.

[0071] In this embodiment, by engraving a pattern on the pad printing piece 40 that can change the amount of ambient light 30 transmitted at the target sidewall 122, the pattern on the pad printing piece 40 is transferred to the target sidewall 122 by the printing head 80 to form a graphic structure 123. This enables high-precision, high-efficiency, high-flexibility, and low-cost printing. It can also be used on objects with complex shapes and irregular surfaces, as well as on various material surfaces. Furthermore, it can use a variety of inks, such as special inks for various materials like plastics, metals, ceramics, and glass, thus enabling the printing of bright and durable patterns.

[0072] In an exemplary embodiment, step 504, which involves patterning the target sidewall 122 of the substrate 124 of each transparent display screen 120, includes forming a checkerboard structure on the target sidewall 122 of the substrate 124 of each transparent display screen 120; wherein the checkerboard structure includes a plurality of black squares arranged at equal intervals along the row and column directions, the row spacing between the multiple rows of black squares is equal, and the multiple columns of black squares are staggered with equal stagger distances.

[0073] Please see Figure 8 , Figure 8 This is a schematic diagram of a checkerboard structure formed on the target sidewall 122 of the substrate 124 of each transparent display panel 120. Optionally, the checkerboard structure is formed on the target sidewall 122 using pad printing technology. The checkerboard structure includes multiple black squares 125 arranged at equal intervals along the row and column directions. The row spacing between multiple rows of black squares 125 is equal, and the column spacing between multiple black squares 125 is staggered with equal stagger distances. The black squares 125 can be coated with a black material 70.

[0074] Through the above checkerboard structure, when ambient light 30 enters the seam 121, it is absorbed by the black squares 125. In areas without black squares 125, the ambient light 30 can pass through normally and enter the human eye, reducing the reflected light entering the field of vision. This weakens the human eye's ability to recognize the seam 121, reducing total internal reflection of ambient light 30 at the seam 121 without completely blocking it, ensuring that some ambient light 30 can pass through normally. Therefore, the result is that the bright line originally formed by the seam 121 becomes darker, but a black line is not formed. Figure 9 As shown.

[0075] Furthermore, the misalignment distance is the size of a black square 125. This allows for a tight misalignment arrangement between the black squares 125, improving the uniformity of absorption and penetration of ambient light 30 at the seams.

[0076] In an exemplary embodiment, step 504, which involves patterning the target sidewall 122 of the substrate 124 of each transparent display screen 120, includes forming a honeycomb structure on the target sidewall 122 of the substrate 124 of each transparent display screen 120. The honeycomb structure includes a plurality of black polygons 126 arranged at equal intervals along the row and column directions, wherein the row spacing between the multiple rows of black polygons 126 is equal, and the multiple columns of black polygons 126 are staggered with equal stagger distances.

[0077] Alternatively, in addition to forming a checkerboard structure on the target sidewall 122 of the substrate 124, a honeycomb structure can also be formed, such as... Figure 10 As shown. The honeycomb structure includes multiple black polygons 126 coated with black material and multiple blank polygons 127 not coated with black material, such as the black polygons 126 and the blank polygons 127 being hexagonal.

[0078] In this embodiment, a honeycomb structure is formed on the target sidewall 122 of the substrate 124. The black polygons 126 of the honeycomb structure have strong symmetry and a tight arrangement, forming a seamless grid or very small gaps, which is suitable for scenes with strong ambient light 30.

[0079] In an exemplary embodiment, step 504, which involves patterning the target sidewall 122 of the substrate 124 of each transparent display screen 120, includes forming an equally spaced vertical strip structure on the target sidewall 122 of the substrate 124 of each transparent display screen 120, or forming an equally spaced horizontal strip structure on the target sidewall 122 of the substrate 124 of each transparent display screen 120.

[0080] Optionally, such as Figure 11 The diagram shows an equally spaced vertical strip structure formed on the target sidewall 122 of the substrate 124 of each transparent display panel 120. The equally spaced vertical strip structure includes a plurality of first rectangles 128 arranged along the width direction of the target sidewall 122, and the width of the first rectangle 128 is equal to the width of the target sidewall 122.

[0081] like Figure 12 The diagram shows an equally spaced horizontal strip structure formed on the target sidewall 122 of the substrate 124 of each transparent display panel 120. The equally spaced horizontal strip structure includes a plurality of second rectangles 129 arranged along the length direction of the target sidewall 122, and the length of the second rectangles 129 is equal to the length of the target sidewall 122.

[0082] Structures such as checkerboard patterns, honeycomb structures, equally spaced vertical strips, and equally spaced horizontal strips can all affect the absorption and penetration of ambient light 30 at the seams, thereby changing the sensitivity of the human eye in recognizing the seams and their shape (bright or dark lines). Furthermore, the graphic structure 123 of the target sidewall 122 can be selected according to the actual intensity of ambient light 30 and requirements.

[0083] In an exemplary embodiment, a target transparent material 130 can also be filled at the seam 121. The refractive index of the target transparent material 130 is close to that of the transparent screen, so that the ambient light 30 at the seam 121 is reflected as little as possible into the human eye, thereby reducing the total internal reflection phenomenon of the ambient light 30 at the seam, while not completely blocking the ambient light 30, ensuring that some of the ambient light 30 can pass through normally. Therefore, the bright line of the original seam can be darkened without forming an obvious black line, such as... Figure 13 As shown.

[0084] It should be understood that, although Figure 5 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 5 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.

[0085] In one exemplary embodiment, please continue to refer to Figure 6 This application also provides a transparent display splicing screen, including: multiple transparent display single screens 120, the graphic sidewalls of the multiple transparent display single screens 120 are spliced ​​together, and the splicing seam formed by the splicing of the graphic sidewalls is used to change the amount of transmitted light of the ambient light 30.

[0086] Because the transparent display panel 120 has patterned sidewalls, when ambient light 30 passes through, the seams formed by the patterned sidewalls alter the amount of light transmitted by the ambient light 30. This causes some light to be absorbed while some light passes through, thus reducing the total internal reflection phenomenon of the ambient light 30 at the seams. At the same time, it does not completely block the ambient light 30, ensuring that some of it can pass through normally. Therefore, it can darken the bright lines of the original seams without forming obvious black lines, avoiding a sense of fragmentation in the displayed image and improving the consistency and integrity of the displayed image.

[0087] In an exemplary embodiment, a graphical structure 123 is formed on the graphical sidewall. The graphical structure 123 is a chessboard structure. The chessboard structure includes a plurality of black squares arranged at equal intervals along the row and column directions. The row spacing between the black squares is equal, and the black squares in the columns are staggered with equal stagger distances.

[0088] In an exemplary embodiment, a patterned structure 123 is formed on the patterned sidewall, and the patterned structure 123 is a honeycomb structure. The honeycomb structure includes a plurality of black polygons arranged at equal intervals along the row and column directions, the row spacing between the multiple rows of black polygons is equal, and the multiple columns of black polygons are staggered with equal stagger distances.

[0089] In one exemplary embodiment, a graphical structure 123 is formed on the graphical sidewall. The graphical structure 123 is an equally spaced vertical strip structure. The equally spaced vertical strip structure includes a plurality of first rectangles arranged along the width direction of the target sidewall, and the width of the first rectangle is equal to the width of the target sidewall.
