Description

Technical Field

[0001] This application belongs to the field of display device technology, and more specifically, relates to a display device and a splicing display device. Background Technology

[0002] With the development of information technology, the market demand for display devices for displaying images is becoming increasingly diversified, including the expansion of display screen sizes. However, large-size screens have higher design requirements and lower production yields, leading to the emergence of alternative solutions, namely video wall technology. This technology achieves the visual effect of a large screen by splicing together smaller screen modules. During the splicing process, it is necessary to align the video wall with cursor marks to ensure that the spliced ​​positions are not misaligned, thus affecting the visual effect.

[0003] Because wide seams in splicing screens can affect the visual effect of products, the seams in splicing screens are designed to be narrower, which can lead to difficulties in identifying the aligning vernier markings. Summary of the Invention

[0004] The purpose of this application is to provide a display device and a splicing display device to solve the technical problem in the prior art where the seams of splicing screens are too narrow, making it difficult to identify the alignment of the vernier mark scale.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A display device is provided, comprising a display panel and a marking area disposed on the display panel. The display panel is used to display image information, and the marking area is disposed on the edge of the display panel for reference when splicing multiple display devices. The marking area includes multiple line pattern groups, which are spaced apart along the extension direction of the edge of the display panel. The multiple line patterns are parallel to the plane of the display panel and extend perpendicular to the extension direction of the edge of the display panel. The width of the line pattern along the extension direction of the edge of the display panel is the same as the spacing between two adjacent line patterns. When multiple display devices are spliced, the line patterns on two adjacent display devices are aligned, and the line patterns on one display device and the line patterns on another display device form a continuous and consistent pattern at the splicing point, thereby ensuring accurate alignment between the two display devices.

[0006] In one alternative embodiment, at least two line patterns have different lengths in a direction perpendicular to the extension direction of the display panel edge.

[0007] In one alternative embodiment, the length ratio of two line patterns with different lengths is greater than 1.5 and less than 2.5.

[0008] In one alternative embodiment, the lengths of two adjacent line patterns are different in a direction perpendicular to the extension direction of the display panel edge.

[0009] In one alternative embodiment, the line pattern group includes a first line pattern and a second line pattern, the length of the first line pattern being greater than the length of the second line pattern, and the first line pattern and the second line pattern being alternately arranged along the extension direction of the edge of the display panel.

[0010] In one alternative embodiment, three first line patterns and two second line patterns are provided, and the three first line patterns and two second line patterns are alternately arranged along the extension direction of the edge of the display panel.

[0011] In one alternative embodiment, adjacent line patterns are different colors.

[0012] In one alternative embodiment, the line pattern is provided with a first color and a second color, and the extension directions of the edges of the first color and the second color display panel are alternately set.

[0013] In one alternative embodiment, the line pattern group includes five line patterns, wherein three line patterns are provided with a first color and two line patterns are provided with a second color, and the first color and the second color are alternately set along the extension direction of the edge of the display panel.

[0014] In one alternative embodiment, each side of the display panel is provided with a marking area.

[0015] In one alternative embodiment, at least three line pattern groups are provided on the respective sides of the display panel, and are evenly spaced on the respective sides of the display panel.

[0016] In one alternative embodiment, the display panel includes a display area and a non-display area, with the non-display area located on the side of the display area and a marking area located at the edge of the non-display area.

[0017] Another objective of this application is to provide a splicing display device, including a base plate and at least two display devices as described above, wherein the at least two display devices are spliced ​​on the base plate and the corresponding line pattern groups on adjacent display devices are aligned.

[0018] The beneficial effects of the display device and splicing display device provided in this application are as follows: Compared with the prior art, the display device of this application provides a marking area on the edge of the display panel. The marking area includes multiple line pattern groups, which are spaced apart along the extension direction of the edge of the display panel. Each line pattern group includes multiple line patterns, which are parallel and spaced apart along the extension direction of the edge of the display panel. Each line pattern is parallel to the plane where the display panel is located and extends in a direction perpendicular to the extension direction of the edge of the display panel. The width of the line pattern along the extension direction of the edge of the display panel is set to be the same as the spacing between two adjacent line patterns. When multiple display devices are spliced... When a line pattern is misaligned, because the width of the line pattern is the same as the spacing between two adjacent line patterns, the misalignment is more easily reflected in the adjacent line patterns, which can easily affect the alignment of other line patterns. Even a slight positional deviation can disrupt the continuity between line patterns, and the discontinuity of the line patterns will be immediately apparent. This makes it easier for operators to identify misaligned line patterns and make corresponding adjustments. Even if the seams of the splicing screen are narrow, the alignment of each display device can be judged by observing whether the line patterns are offset, which solves the problem of difficulty in identifying the alignment cursor scale caused by the narrow seams of traditional splicing screens.

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0030] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", 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 application 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 application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] With the development of information technology, the market demand for display devices for displaying images is becoming increasingly diversified, including the expansion of display screen sizes. However, large-size screens require higher design technology and have lower production yields. This has led to the development of alternative solutions, namely video wall technology, which achieves the visual effect of a large screen by splicing together smaller screen modules. During the splicing process, alignment marks are required to ensure that the spliced ​​positions are not misaligned, thus affecting the visual effect. Because excessively wide seams in video walls can negatively impact the product's visual appeal, the seams are designed to be narrower. This presents challenges in identifying the alignment marks and ensuring proper alignment during splicing.

[0033] Please refer to the following: Figures 1 to 5 The display device 100 provided in the embodiments of this application will now be described. The display device 100 includes a display panel 10 and a marking area (not shown in the figure) disposed on the display panel 10. The display panel 10 is used to display image information. The marking area is disposed on the edge of the display panel 10 and is used for reference when splicing multiple display devices 100. The marking area includes multiple line pattern groups 20, which are spaced apart along the extension direction of the edge of the display panel 10. Multiple line patterns 21 are parallel to the plane on which the display panel 10 is located and extend in a direction perpendicular to the extension direction of the edge of the display panel 10. The width of the line pattern 21 along the extension direction of the edge of the display panel 10 is the same as the spacing between two adjacent line patterns 21. When multiple display devices 100 are spliced, the line patterns 21 on two adjacent display devices 100 are respectively aligned. The line patterns 21 on one display device 100 and the line patterns 21 on another display device 100 form a continuous and consistent pattern at the splicing point, so that the two display devices 100 are accurately aligned.

[0034] In this application, "multiple" refers to two or more. The display panel 10 of the display device 100 is used to present clear, color-accurate and fast-response images, providing high-quality visual display effects; the marked area on the display panel 10 is used for alignment reference when splicing multiple display devices 100, ensuring that each display device 100 can be accurately spliced ​​together, avoiding visual defects caused by inaccurate splicing.

[0035] The marking area includes multiple line pattern groups 20. The number of line pattern groups 20 can be set to two, three, or four. The marking area is located at the edge of the display panel 10, and can be located only on one side of the display panel 10 (such as the top, bottom, left, or right), suitable for unidirectional splicing scenarios, for example... Figure 2 When the two display devices 100 shown are spliced ​​together, only a marking area needs to be set on one side of the display panel 10. When the design of the splicing screen allows other edges to be aligned without alignment, such as horizontal or vertical arrangement, the design can be simplified and unnecessary markings reduced. Markings can also be located on both sides of the display panel 10, such as opposite sides or adjacent sides, suitable for scenarios requiring bidirectional alignment, and for display devices 100 that have both horizontal and vertical splicing requirements, such as... Figure 4 If the four display devices 100 shown are to be spliced ​​together, then marking areas need to be set on both sides of two display devices 100 to provide more comprehensive reference points and ensure splicing accuracy in both directions. For example... Figure 1Furthermore, marking areas can be set on all four edges of the display panel 10, which is suitable for complex splicing scenarios and large-scale video walls spliced ​​in multiple directions. It provides all-round reference points to ensure high-precision alignment can be achieved no matter which direction the splicing is from.

[0036] In this application, as Figure 2 The direction in which the edge of the display panel 10 extends is the first direction, i.e., the Y direction; the direction perpendicular to the direction in which the edge of the display panel 10 extends is the second direction, i.e., the X direction. By arranging multiple line patterns 21 parallel to the plane on which the display panel 10 is located and extending along the second direction, clear reference lines are provided, making it easier for operators to confirm whether the screen is correctly spliced.

[0037] By arranging multiple line patterns 21 parallel and spaced along a first direction, with the width of the line pattern 21 along the first direction being the same as the spacing between two adjacent line patterns 21, when multiple display devices 100 are spliced ​​together, if there is misalignment, it can be more easily reflected to other line patterns 21 when one misalignment occurs. Even a slight positional deviation will cause the continuity between line patterns 21 to be disrupted, and the discontinuity of the line patterns 21 will be immediately apparent, making it easier for operators to identify the misalignment and make corresponding adjustments.

[0038] Therefore, even if the seams between the spliced ​​screens are narrow, the alignment of the two screens can be determined by observing whether the line pattern 21 is offset, solving the problem of difficulty in identifying the alignment cursor scale caused by excessively narrow seams in traditional spliced ​​screens. Furthermore, this method allows for faster and more efficient screen alignment, significantly reducing debugging time.

[0039] Accurate alignment not only avoids visual interference caused by misalignment at the seams of the display devices 100, but also ensures the continuity and integrity of the entire splicing screen, thus providing a better viewing experience.

[0040] like Figure 2 The width D of the multiple line patterns 21 and the spacing d between two adjacent line patterns 21 are D1=D2=D3=D4=D5=d1=d2=d3=d4.

[0041] The specific length and width of the line pattern 21 can be set according to the size of the display device 100 and the size of the marking area. The line pattern 21 has sufficient length and width to be easily identifiable by the naked eye, and does not affect the display area 11 or cause unnecessary visual interference.

[0042] The specific shape of the line pattern 21 can be rectangular, which is regular and easy to identify and align; it can also be circular, which has good symmetry and can be aligned at any angle, making it suitable for scenarios that require splicing in multiple directions; it can also be L-shaped or T-shaped, which can provide clear reference points for the positions of two directions between adjacent screens.

[0043] The marking area can be set in the center of the edge of the display panel 10 to quickly determine the alignment. Alternatively, marking area cursors can be set near the four corners of the display panel 10 to ensure perfect alignment even at the corners. Or, depending on the size of the display device 100, multiple marking areas can be evenly spaced on the mating edge to ensure good alignment of the entire display device 100.

[0044] In a large-scale splicing display device 100 scenario, even a small deviation between each pair of adjacent display devices 100 can lead to significant accumulated errors throughout the system. By setting the width of each line pattern 21 to be the same as the spacing between two adjacent line patterns 21, a clear and consistent reference point can be provided between adjacent display devices 100. By ensuring precise alignment at each splicing point, errors can be prevented from being passed from one unit to the next, effectively reducing these accumulated errors and maintaining high alignment accuracy across the entire splicing screen. Accurate alignment not only improves the visual effect but also ensures the tightness of the physical connection between each display device 100, thereby reducing potential failure points caused by loosening or displacement, helping to extend the equipment's lifespan and maintain performance stability.

[0045] During assembly, clear and easily identifiable marking areas speed up the assembly process. The design of line pattern 21 makes misalignment easier to spot, allowing for quick adjustments, reducing installation difficulty, simplifying the alignment process, reducing the time required for repeated corrections, and lowering the rework rate due to misjudgment.

[0046] The display device 100 provided in this application, compared with the prior art, provides a marking area on the edge of the display panel 10. The marking area includes multiple line pattern groups 20, which are spaced apart along a first direction. Each line pattern group 20 includes multiple line patterns 21, which are spaced apart along the first direction. Each line pattern 21 is parallel to the plane of the display panel 10 and extends along a second direction. The width of each line pattern 21 along the first direction is set to be the same as the spacing between two adjacent line patterns 21. When multiple display devices 100 are spliced ​​together, if a line pattern 21 is misaligned at a certain point, the width of the line pattern 21 will be equal to the spacing between adjacent line patterns 21. The equal spacing between adjacent line patterns 21 makes misalignment more easily reflected in adjacent line patterns 21, which can easily affect the alignment of other line patterns 21. Even a slight positional deviation can disrupt the continuity between line patterns 21, and the discontinuity of line patterns 21 will be immediately apparent. This makes it easier for operators to identify misaligned line patterns 21 and make corresponding adjustments. Even if the seams of the splicing screen are narrow, it is possible to determine whether each display device 100 is correctly aligned by observing whether the line patterns 21 are offset. This solves the problem of difficulty in identifying the alignment cursor scale caused by the narrow seams of traditional splicing screens.

[0047] In another embodiment of this application, please refer to Figure 2 At least two line patterns 21 have different lengths in a direction perpendicular to the extension direction of the edge of the display panel 10.

[0048] By setting at least two line patterns 21 to have different lengths in the direction perpendicular to the edge of the display panel 10, the different lengths of the line patterns 21 can create obvious visual differences, providing richer visual reference points and making misalignment more prominent, thus helping operators to more easily judge whether alignment is correct. If all line patterns 21 are the same length, it may be difficult to quickly judge whether alignment is correct due to visual repetition and symmetry. By setting different lengths, the differences between the line patterns 21 are more obvious, reducing the risk of misjudgment caused by the line patterns 21 being too uniform.

[0049] Because the line pattern 21 of different lengths provides clear visual feedback, it enhances the intuitiveness of the calibration process, enabling operators to complete the alignment work faster and more accurately. This not only shortens the installation time but also reduces the risk of rework due to misoperation and improves work efficiency.

[0050] The number of line patterns 21 of different lengths can be set to two or three, such as... Figure 2 The number of line patterns 21 of different lengths is set to five for easy identification. Furthermore, two or three different length types can also be used, such as... Figure 2Two different length types are set. Patterns L1, L3 and L5 have the same length along the second direction, that is, length l1=l3=l5. Patterns L2 and L4 have the same length along the second direction, that is, length l2=l4. The length of pattern L1 along the second direction is different from that of pattern L2 along the second direction, which further enhances the differentiation of line patterns 21 and makes even small deviations quickly identifiable.

[0051] In another embodiment of this application, the length ratio of two line patterns 21 with different lengths is greater than 1.5 and less than 2.5.

[0052] A length ratio between 1.5 and 2.5 ensures that the differences between line patterns 21 are sufficiently noticeable without being too disparate, thus providing a clear reference while maintaining overall design consistency. If the ratio is too small, such as 1, the length differences of the line patterns 21 will not be significant enough, potentially making it difficult for operators to quickly identify the alignment status. If the ratio is too large, such as 4, the longer line patterns 21 may appear too prominent, while the shorter line patterns 21 may be overlooked, resulting in an unbalanced reference information.

[0053] A length ratio between 1.5 and 2.5 strikes a balance, providing sufficient visual contrast through length differences without compromising the overall harmony of the pattern. This range strikes a balance between difference and consistency, ensuring the recognizability of the line pattern 21 while maintaining the overall design's harmony. A reasonable length ratio makes misalignment during splicing easier to detect; operators can quickly determine if the spliced ​​screens are aligned by observing the continuity of the line pattern 21, thus improving calibration efficiency. Furthermore, a length ratio between 1.5 and 2.5 ensures the compactness of the marking area, avoiding excessive use of the display panel 10's edge space.

[0054] In one embodiment, the length ratio of two line patterns 21 with different lengths is set to 1.5. The length difference between the two line patterns 21 is small, and the visual contrast is not too strong. Because the difference is small, the operator can focus more on subtle deviations and avoid ignoring minor misalignments due to excessive length differences, which is suitable for scenarios requiring high-precision alignment.

[0055] In another embodiment, the length ratio of two line patterns 21 with different lengths is set to 2. The length difference between the two line patterns 21 is more obvious, making the misalignment more noticeable, thereby simplifying the alignment judgment process and maintaining a certain degree of overall coordination while providing a clear reference.

[0056] In another embodiment, the length ratio of the two line patterns 21 with different lengths is set to 2.5. The length difference between the two line patterns 21 is very obvious, which helps the operator to quickly complete the alignment calibration and reduces the time spent on repeated adjustments; and because the difference is obvious, the operator can quickly locate the problem and make adjustments.

[0057] In another embodiment of this application, please refer to Figure 2 The lengths of two adjacent line patterns 21 in the direction perpendicular to the extension direction of the edge of the display panel 10 are not the same.

[0058] By setting different lengths for two adjacent line patterns 21 along a direction perpendicular to the edge of the display panel 10, a more differentiated visual feedback mechanism can be created. This leverages the human visual system's sensitivity to proportion and contrast, enhancing the recognizability of the alignment status. When the lengths of two adjacent line patterns 21 are all different, any deviation at the splicing point will disrupt the continuity of the line patterns 21. This disruption is easily noticeable, guiding operators to make positioning adjustments. By setting different lengths for two adjacent line patterns 21 along the second direction, the alignment accuracy of the splicing screen can be significantly improved. Precise alignment can avoid obvious gaps or misalignments at the edges of the splicing screen, thereby improving the overall visual effect.

[0059] The line patterns 21 of different lengths provide multiple verification points during the splicing process, ensuring that each key position can be accurately aligned. Furthermore, the distribution of multiple line patterns 21 of different lengths at different positions on the display panel 10 can cover more alignment requirements. In complex splicing scenarios, the line patterns 21 of different lengths can provide more comprehensive reference points, better guide operators to complete the alignment work, and ultimately achieve seamless splicing, ensuring the integrity and smoothness of the image.

[0060] Furthermore, different length types can be set to two, three, or more. In one embodiment, the length of multiple line patterns 21 along the second direction can gradually increase or decrease along the first direction. Through the step-like length changes, a progressive alignment reference can be provided for the splicing display device 100. Since the length of each line pattern 21 changes gradually, the operator can judge whether the screen is accurately aligned by observing whether these length changes are continuous. The operator can quickly detect and correct small deviations based on the continuity of the steps, avoiding these small errors from accumulating into larger problems in subsequent splicing. If the step-like length change at the splicing point is interrupted or discontinuous, it indicates that there is a misalignment. This design enhances the recognizability of the alignment status, making any deviation more intuitive. Each time splicing is performed, the step-like length change can provide immediate visual feedback, simplifying the calibration process and making installation and adjustment more intuitive and efficient.

[0061] In another embodiment, the lengths of the multiple line patterns 21 along the second direction are all different and are staggered. The staggered arrangement of line patterns 21 with different lengths enhances the recognizability of the alignment state, making any deviation more intuitive. Since each line pattern 21 has a different length and is staggered, it forms a unique visual pattern. This uniqueness allows each line pattern 21 to serve as an independent reference point, thereby improving the accuracy of alignment and better avoiding visual confusion caused by excessive repetition of line patterns 21.

[0062] In another embodiment of this application, please refer to Figure 2 The line pattern group 20 includes a first line pattern 211 and a second line pattern 212. The length of the first line pattern 211 is greater than the length of the second line pattern 212. The first line pattern 211 and the second line pattern 212 are alternately arranged along the extension direction of the edge of the display panel 10.

[0063] The first line pattern 211 and the second line pattern 212 are alternately arranged along the edge of the display panel 10, that is, two line patterns 21 of different lengths are alternately arranged, providing a more regular visual pattern. Operators only need to ensure that these patterns are continuous and consistent at the splicing points to complete the alignment work, which greatly reduces calibration time and difficulty, simplifies the calibration process, and makes installation and adjustment more intuitive and efficient. By alternately setting line patterns 21 of different lengths, the alignment accuracy of the splicing display device 100 can be significantly improved.

[0064] When using three or four different lengths of line pattern 21, a certain difference is needed between each length to ensure they can be distinguished, and these length differences accumulate and occupy more edge space of the display panel 10. However, by using two alternating lengths, only a fixed length difference is needed to achieve effective visual contrast, thereby reducing the overall required marking area space.

[0065] The alternating lengths maintain the compactness of the marking area, occupying less space while ensuring easy identification of the line pattern 21 for alignment of the display device 100. This provides sufficient reference points even in limited spaces for alignment. The alternating lengths reduce design and usage complexity, making it easier for operators to align multiple display devices 100 and improving work efficiency.

[0066] In another embodiment of this application, please refer to Figure 2 There are three first line patterns 211 and two second line patterns 212. The three first line patterns 211 and the two second line patterns 212 are arranged alternately along the extension direction of the edge of the display panel 10.

[0067] like Figure 2 Five line patterns 211 and 212 are alternately arranged along the extension direction of the edge of the display panel 10. The first line patterns 211 are L1, L3 and L5, and the second line patterns 212 are L2 and L4. The five line patterns 21 are alternately arranged as a group of line patterns 20, which is sufficient to identify the alignment during splicing, making it easy to reduce the area occupied by the marking area while being identifiable by the naked eye.

[0068] In another embodiment of this application, reference is made to Figure 1 and Figure 2 The colors of two adjacent line patterns 21 are different.

[0069] By setting different colors between two adjacent line patterns 21, the visual recognizability of the line patterns 21 can be enhanced, making them easier to identify and improving the alignment. Color differences are easily captured visually, and color changes provide clear reference information. Through color contrast, the boundaries between adjacent line patterns 21 become clearer. Misalignment will result in obvious misalignment of color boundaries. The highly visual feedback mechanism allows operators to quickly identify and make adjustments, significantly improving the alignment accuracy of the splicing display device 100. Color changes add an extra visual dimension, making any misalignment more obvious and reducing the possibility of misjudgment.

[0070] In one embodiment, a color combination with a high-ratio ratio, such as red and green, or yellow and blue, is used to ensure good visibility in both bright and low-light environments. In another embodiment, colored fluorescent materials can be used to emit bright light under specific light sources, facilitating identification and alignment.

[0071] In another embodiment of this application, reference is made to Figure 2 The line pattern 21 has a first color and a second color, and the first color and the second color are set alternately.

[0072] By using alternating colors, such as red and green, or blue and yellow, visual differentiation can be significantly improved. The background color of the display device 100 is generally black; choosing a color with strong contrast to the background ensures that the line pattern 21 is clearly visible even at a distance. Furthermore, considering wear and tear from long-term use, durable and fade-resistant materials can be selected for its construction.

[0073] The alternating color design provides instant alignment feedback; if two adjacent screens are not perfectly aligned, color boundaries will appear misaligned or discontinuous, making the changes more noticeable. In one embodiment, reference... Figure 3 and Figure 4The first and second colors are set to red and green, respectively. When horizontal splicing is performed, if a display device 100 is slightly offset, the original continuous "red-green-red-green-red" color sequence of the marked area will become a "red-red-green-green-red-green-green-red-red" sequence, making it easier for operators to notice this obvious color misalignment and make adjustments.

[0074] The alternating color design reduces monotony and repetition by introducing color variations, thus reducing visual fatigue and allowing operators to maintain high levels of concentration and accuracy during long working hours.

[0075] In another embodiment of this application, reference is made to Figure 2 The line pattern group 20 includes five line patterns 21, of which three line patterns 21 are provided with a first color and two line patterns 21 are provided with a second color. The first color and the second color are alternately set along the extension direction of the edge of the display panel 10.

[0076] Three line patterns 21 are set to the first color, and two line patterns 21 are set to the second color. The first color and the second color are set alternately. That is, the three line patterns 21 with the first color and the two line patterns 21 with the second color are set alternately along the extension direction of the edge of the display panel 10 to form a color misalignment, which is convenient for alignment.

[0077] In addition, the length of the three line patterns 21 with the first color is greater than the length of the two line patterns 21 with the second color, which further improves the distinguishability and makes it easier to identify the line patterns 21 and perform precise alignment operations.

[0078] In another embodiment of this application, please refer to Figure 1 Each side of the display panel 10 is provided with a marking area.

[0079] By setting marked areas on all sides of the display panel 10, clear alignment reference points can be obtained for both horizontal and vertical splicing. This helps to detect and correct deviations in multiple directions, thereby improving the overall splicing quality and ensuring that the display device 100 can achieve high-precision alignment in all directions.

[0080] The number of line pattern groups 20 set on each side of the display panel 10 can also be selected as needed. One line pattern group 20 can be set in the middle position, or two line pattern groups 20 can be set on both sides.

[0081] Different shapes and orientations require precise alignment from multiple angles. Marking areas on all sides of the display panel 10 provide comprehensive reference points to ensure that each splicing point is accurately aligned, regardless of its position and orientation, thus adapting to complex splicing layouts.

[0082] Because there are marked areas on each side, operators can start splicing from any direction and adjust the position of the screen at any time during installation without worrying about a lack of alignment reference, which improves the flexibility of the installation process and allows the position of the display device 100 to be flexibly adjusted according to specific application scenarios.

[0083] In another embodiment of this application, please refer to Figure 1 At least three line pattern groups 20 are provided on the corresponding side of the display panel 10, and are evenly spaced on the corresponding side of the display panel 10.

[0084] By setting at least three evenly distributed line pattern groups 20, the entire side can be covered, providing a more comprehensive alignment reference and ensuring that each key position can be aligned using the corresponding line pattern group 20, with a clear reference point. For example... Figure 1 Marking areas are provided on both sides and the middle of the corresponding sides of the display panel 10 to ensure that the splicing screen can be accurately aligned in all positions.

[0085] Evenly spaced marking areas can create a coherent visual feedback along the entire side. Operators can judge the status of the entire screen by observing whether these marking areas are aligned, rather than relying solely on a single point or local area. This enhances the alignment consistency of the splicing screen and reduces the possibility of local deviations.

[0086] Multiple marked areas provide instant feedback during the splicing process, allowing operators to quickly identify and correct minor deviations, preventing these small errors from accumulating into larger problems in subsequent splicing. For large screens, a single marked area may not cover the entire side, easily leading to localized deviations. Setting three evenly distributed marked areas better meets the alignment requirements of large screens.

[0087] In another embodiment of this application, please refer to Figure 1 The display panel 10 includes a display area 11 and a non-display area 12. The non-display area 12 is located on the side of the display area 11, and the marking area is located at the edge of the non-display area 12.

[0088] The marked area is set in the non-display area 12. The marked area will not occupy any space actually used to display images, videos or other content. This ensures that the presence of the marked area will not interfere with or obscure the content of the display area 11. This can maximize the effective display area of ​​the display panel 10 and not affect the user's viewing experience.

[0089] Because the non-display area 12 is located to the side of the display area 11, the marked area is easier to observe during alignment. By placing the marked area in the non-display area 12, the display area 11 appears cleaner and simpler, without unnecessary lines or patterns interfering with the visual effect, enhancing the overall aesthetics of the product and making the device look more professional and tidy. The non-display area 12 does not directly participate in information display, therefore it is less likely to be physically touched, reducing the risk of wear or damage to the line patterns 21 due to frequent touching, cleaning, or other operations, allowing for long-term maintenance and preservation of marking clarity.

[0090] In one embodiment, each side of the display area 11 is provided with a non-display area 12. This ensures that the display device 100 can be spliced ​​in multiple directions. Each side has a marked area, providing a comprehensive alignment reference point, enabling precise alignment regardless of the starting direction of splicing. The marked areas on all four sides allow operators to choose the most suitable splicing direction and order according to actual needs, without worrying about the lack of alignment references in certain directions, increasing flexibility in the splicing process. The multi-directional marked areas allow operators to quickly find and use the nearest alignment reference point, reducing the time spent searching for suitable reference points, simplifying the installation and adjustment process, and improving work efficiency.

[0091] In addition, magnetic components, such as small magnetic blocks or magnetic strips, can be provided at the edge of the display panel 10. Through the interaction of magnetic forces, when two display devices 100 are brought close together, the magnetic components will automatically attract and adjust their position, thereby achieving rapid alignment.

[0092] Please see Figures 3 to 5 This application also provides a splicing display device 200, including a base plate 210 and at least two display devices 100 as described above. The at least two display devices 100 are spliced ​​on the base plate 210, and the corresponding line pattern groups 20 on adjacent display devices 100 are aligned.

[0093] By splicing display devices 100 on the base plate 210 and aligning the corresponding line pattern groups 20 on two adjacent display devices 100, operators can use the alignment of multiple line patterns 21 in the line pattern group 20 to make the two adjacent display devices precisely aligned, reducing gaps caused by inaccurate splicing and ensuring the consistency and integrity of the overall display effect.

[0094] The base plate 210 provides a unified mounting platform, enabling the various display devices 100 to be spliced ​​on the same plane. All display devices 100 are fixed to the same base plate 210, forming an integral structure, which improves the physical stability of the equipment, reduces splicing errors caused by the movement or vibration of individual screens, and the alignment of the marked areas further ensures that the position of each display device 100 is fixed and consistent.

[0095] By mounting it on the base plate 210, it can be applied to various usage scenarios. The installation of the video wall screen is achieved simply by installing the base plate 210. The design of the base plate 210 and the marked area provides a reliable alignment reference. For example, in large event venues, conference rooms, or outdoor billboards, this design ensures that the video wall display device 200 maintains a high-quality display effect.

[0096] In addition, an initial point can be set on the base plate 210, and the display devices 100 can be spliced ​​from the initial point. The initial point can also be marked with a marking area so that the marking areas on the display devices 100 can be aligned, providing a clear starting reference point for the splicing process, ensuring that all display devices 100 are aligned with the same reference, and avoiding overall splicing errors caused by the lack of a fixed starting point.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
