[0042] Figure 1 A schematic diagram illustrating the structure of a display device provided in an embodiment of this disclosure is shown. Figure 1 As shown, the display device has multiple curved display areas 1, and the multiple curved display areas 1 are spliced together to form an irregularly shaped display area. Each curved display area 1 includes multiple spliced display units 11. That is, the display device includes multiple sets of display units 11, each set of display units 11 is spliced together to form a curved display area 1, and the multiple curved display areas 1 are spliced together to form an irregularly shaped display area.
[0043] Each display unit 11 is a triangular structure. The radius of curvature of each display unit 11 within a curved display area 1 is equal. Multiple curved display areas 1 have multiple vertices, and the vertices of each curved display area 1 can form a regular polygon.
[0044] In this embodiment, a curved display area 1 is formed by splicing together a group of display units 11, and then multiple curved display areas 1 are spliced together to form an irregular display area, so as to realize the display of irregular images on the display device, thereby improving the display effect of the display device, increasing user stickiness, and giving users a better sense of immersion; in addition, each display unit 11 in the curved display area 1 is set as a triangular structure to reduce the number of types of display units 11, and at the same time facilitate the arrangement of pixels on the display unit 11, thereby reducing the mold opening cost of the display unit 11 and reducing the manufacturing difficulty of the display device.
[0045] The display unit 11 can be a Mini LED light board, and the display unit 11 has a planar triangular structure. For example, the display unit 11 is a glass-based display unit 11, which makes it easier to splice glass-based display units 11 to obtain a display device with an irregularly shaped display area; or, the display unit 11 has a curved triangular structure. For example, the display unit 11 is a PCB-based display unit 11, which can better achieve the curved effect of the irregularly shaped display area after splicing multiple sets of PCB-based display units 11.
[0046] In this case, the radius of curvature of each display unit 11 within the curved display area 1 is equal, meaning that the curved display area 1 is approximately a part of a sphere. Thus, the display area of the display device can be divided using the same sphere radius and the inscribed regular polyhedron of the sphere, resulting in curved display areas 1 corresponding to the polygonal faces of the regular polyhedron, and thus multiple curved display areas.
[0047] The regular polygon formed by the multiple vertices of the curved display area 1 can be an equilateral triangle 2, a regular quadrilateral or a regular pentagon 3, etc. In this way, for each curved display area 1, it is easier to perform topological division by display units 11 with triangular structures, so as to ensure that the structural dimensions of each display unit 11 in the curved display area 1 are closer, thereby reducing the number of different structural dimensions of the display unit 11.
[0048] The structural dimensions and number of display units 11 within the curved display area 1 can be determined based on the triangular topological division structure of the regular polygons connected to the vertices of the curved display area 1. When performing triangular topological division of the regular polygons connected to the vertices of the curved display area 1, it is only necessary to ensure that the side length of the smallest triangle 21 after division is slightly greater than 7 centimeters.
[0049] Of course, the side length of the smallest triangle 21 can also be less than 7 centimeters. Depending on the actual application scenario, as long as a display unit 11 with a structural size close to that of the smallest triangle 21 can be manufactured based on the corresponding manufacturing process, this disclosure does not limit this.
[0050] For example, when the vertices of the curved display area 1 can form an equilateral triangle 2, the number of display units 11 in the curved display area 1 can be determined by performing a triangular topological division on the equilateral triangle 2. After the topological division, the number of the smallest triangle 21 is the number of display units 11, and the size of the triangle formed by the three projection points O2 of the three vertices of the smallest triangle 21 on the curved display area 1 is the structural size of a display unit 11.
[0051] Regarding the topological partitioning of equilateral triangle 2, the first topological partitioning method is as follows: Figure 2 As shown, the sides of equilateral triangle 2 are divided into equal parts (e.g., bisection, trisection, etc.), and then straight lines parallel to the other sides are drawn through the points of division on the sides to divide equilateral triangle 2 into multiple smallest triangles 21 (the side length of the smallest triangle 21 is slightly greater than 7 cm).
[0052] The second topology partitioning method, such as Figure 3 As shown, the sides of equilateral triangle 2 are bisected, and the projection points O1 of the bisecting points on the sides onto the curved display area 1 are determined. Then, based on the three projection points O2, equilateral triangle 2 is divided into four smaller triangles. The bisecting operation and the projection point O2 of the bisecting points O1 onto the curved display area 1 are repeated until multiple smallest triangles 21 are obtained based on multiple projection points O2 on the curved display area 1 (the side length of the smallest triangle 21 is slightly greater than 7 cm).
[0053] For example, when the vertices of the curved display area 1 can form a regular pentagon 3, the number of display units 11 in the curved display area 1 can be determined by performing a triangular topological division on the regular pentagon 3. After the topological division, the number of the smallest triangles 21 is the number of display units 11, and the size of the triangle formed by connecting the three projection points O2 of the three vertices of the smallest triangle 21 on the curved display area 1 is the structural size of a display unit 11.
[0054] For the topological partitioning of a regular pentagon 3, the first topological partitioning method is as follows: Figure 4 As shown, based on the face center O3 of regular pentagon 3 and the five vertices of regular pentagon 3, regular pentagon 3 is divided into five congruent main triangles 31. Then, the sides of each main triangle 31 are divided equally (e.g., bisected, trisected, etc.), and straight lines parallel to other sides are drawn through the division points on the sides to divide the five main triangles 31 into multiple minimum triangles 21 (the side length of the minimum triangle 21 is slightly greater than 7 cm).
[0055] The second topological partitioning method involves determining the projection point of the face center O3 of the regular pentagon 3 onto the curved display area 1. Based on the projection points corresponding to the five vertices of the pentagon and the face center O3, the pentagon is divided into five congruent principal triangles 31. The sides of each principal triangle 31 are bisected, and the projection points O2 of the bisecting points O1 on the curved display area 1 are determined. Then, based on the multiple projection points O2, each principal triangle 31 is divided into multiple smaller triangles. The bisecting operation and the operation of the bisecting points O1 onto the curved display area 1 are repeated until multiple minimum triangles 21 are obtained based on the multiple projection points O2 on the curved display area 1 (the side length of the minimum triangle 21 is slightly greater than 7 cm).
[0056] It should be noted that when performing topological division of the regular polygons in the curved display area 1, as the division level increases, that is, as the number of minimum triangles 21 increases, the sizes of the multiple minimum triangles 21 after division become closer and closer. Consequently, the structural sizes of the multiple display units 11 within the curved display area 1 become closer and closer. It is even possible to use multiple display units 11 with the same structural size to meet the splicing requirements, thereby reducing the manufacturing difficulty of the display device and ensuring the display effect of the screen within the curved display area 1 after splicing multiple display units 11.
[0057] In this design, for multiple display units 11 of a single structural size, to ensure the display effect when splicing them together to form a display device, the spacing between adjacent display units 11 can be adjusted. Specifically, when the actual size of a display unit 11 is slightly smaller than its theoretical size, the spacing between adjacent display units 11 can be increased; when the actual size of a display unit 11 is slightly larger than its theoretical size, the spacing between adjacent display units 11 can be decreased. When adjusting the spacing between adjacent display units 11, it is essential to ensure that the spacing between adjacent display units 11 is less than the spacing between adjacent light-emitting devices (such as miniLEDs) to avoid black shadows appearing at the splicing seam when the display device shows an image.
[0058] In some implementations, the regular polygons formed by the vertices of each curved display area 1 are congruent polygons. That is, the size of each curved display area 1 is basically the same. Thus, the structural dimensions of the display units 11 at corresponding positions within multiple curved display areas 1 are basically the same, thereby further reducing the mold opening cost of the display units 11 and reducing the manufacturing difficulty of the display device.
[0059] For example, the polygon formed by the vertices of the surface display area 1 is an equilateral triangle 2, and the equilateral triangle 2 formed by the vertices of each surface display area 1 is a congruent equilateral triangle 2.
[0060] Optionally, the curvature of multiple curved display areas 1 is all equal. In this case, the irregularly shaped display area formed by splicing multiple curved display areas 1 corresponds to a portion of the sphere. For example, the irregularly shaped display area formed by splicing multiple curved display areas 1 is a hemispherical display area or a spherical crown-shaped display area. In this way, for an irregularly shaped display area that corresponds to a portion of the sphere, the user's viewing angle can be increased, avoiding visual blind spots when the user is watching, thereby further enhancing the user's sense of immersion when watching.
[0061] In some implementations, such as Figure 1 or Figure 5 As shown, multiple curved display areas 1 are spliced together to form a spherical display area, and the vertices of the multiple curved display areas 1 can form an inscribed regular polyhedron of the spherical display area.
[0062] Thus, the spliced spherical display areas can expand the application scenarios of display devices, such as in the XR field. In addition, since the vertices of multiple curved display areas 1 can form a regular polyhedron, that is, each curved display area 1 corresponds to a regular polygon face of the regular polyhedron, the multiple curved display areas 1 have the same size. Therefore, when determining the number of display units 11 and the structural dimensions of each display unit 11 in multiple curved display areas, it is only necessary to determine the number of display units 11 and the structural dimensions of each display unit 11 in one curved display area 1. This can further reduce the mold opening cost of display units 11 and reduce the manufacturing difficulty of display devices.
[0063] Optionally, the regular polyhedron that can be formed by the vertices of multiple curved display areas 1 can be a regular icosahedron composed of twenty equilateral triangles (2 faces) or a regular dodecahedron composed of twelve regular pentagons (3 faces). Of course, the regular polyhedron that can be formed by the vertices of multiple curved display areas 1 can also be a regular tetrahedron composed of four equilateral triangles (2 faces), a regular octahedron composed of eight equilateral triangles (2 faces), or a regular hexahedron composed of six square faces.
[0064] When the vertices of multiple curved display areas 1 can form a regular icosahedron, such as Figure 1 As shown, the display device has twenty curved display areas 1, and each curved display area 1 has three vertices. The vertices of the twenty curved display areas 1 can form an inscribed regular icosahedron of the spherical display area.
[0065] Thus, based on the icosahedron, the spherical display area is divided into twenty curved display areas 1 of the same size. Since the icosahedron is the regular polyhedron that is closest to the sphere, when performing triangular topological division on the twenty curved display areas 1, the resulting minimum triangle 21 mesh has more uniform geometric properties. That is, the structural dimensions of the triangular display units 11 included in the twenty curved display areas 1 are almost the same, thereby reducing the number of structural dimensions of the display units 11 and reducing the manufacturing difficulty of the display device.
[0066] In conjunction with the above description of the topological division of the equilateral triangle 2, the number of display units 11 included in the curved display area 1 and the structural dimensions of each display unit 11 can be determined.
[0067] Combining the second topology partitioning method described above, since each topology partitioning is based on the projection of the vertices of the triangle onto the curved display area 1, the structural dimensions of the multiple display units 11 within the curved display area 1 obtained through the second topology partitioning method are closer, ensuring that the difference in structural dimensions between any two display units 11 is within the tolerance range of the display unit 11 manufacturing process. Thus, in the actual manufacturing of the multiple display units 11, the structural dimensions of the multiple display units 11 within the curved display area 1 can be made completely identical, thereby ensuring that the structural dimensions of the display units 11 within the twenty curved display areas 1 are the same. Therefore, when manufacturing the display device, only multiple display units 11 with the same structural dimensions are needed, and a display device with a spherical display can be obtained by splicing them together.
[0068] For multiple display units 11 with the same structural size, when splicing them together to obtain a display device, the specific splicing method can refer to the splicing method of multiple display units 11 with the same structural size described above. This embodiment will not be repeated here.
[0069] When the vertices of multiple curved display areas 1 can form a regular dodecahedron, such as Figure 5 As shown, the display device has twelve curved display areas 1, and each curved display area 1 has five vertices. The vertices of the twelve curved display areas 1 can form an inscribed regular dodecahedron of the spherical display area.
[0070] Thus, based on the regular dodecahedron, the spherical display area is divided into twelve curved display areas 1 of the same size. Therefore, when performing triangular topological division on the twelve curved display areas 1, the resulting smallest triangle 21 mesh has more uniform geometric properties in the circumferential direction with the center point of the curved display area 1 as the center. This reduces the number of structural dimensions of the display unit 11 within the curved display area 1, thereby reducing the manufacturing difficulty of the display device.
[0071] In conjunction with the above description of the topological division of the regular pentagon 3, the number of display units 11 included in the curved display area 1 and the structural dimensions of each display unit 11 can be determined.
[0072] Combining the first topological partitioning method described above, the curved display area 1 includes multiple rings of display units 11, centered on the center point of the curved display area 1 and sequentially spliced outwards. After performing triangular topological partitioning on the regular pentagon 3, it is known that the smallest triangle 21 mesh includes multiple rings of vertices radially outwards from the face center O3 of the pentagon, and the distances from multiple vertices of each ring to the projection point O2 of the curved display area 1 are equal, thus ensuring that the structural dimensions of each ring of display units 11 are the same. When equally dividing the sides of the main triangle 31, the more equal parts there are, the closer the structural dimensions of adjacent rings of display units 11 are, thus ensuring that the difference in structural dimensions between adjacent rings of display units 11 is within the tolerance range of the manufacturing process of the display units 11. This facilitates the adjustment of the structural dimensions of one ring of display units 11 among adjacent rings of display units 11, further reducing the number of different structural dimensions of the display units 11 included in the display device.
[0073] Figure 6 An example of a screen splitting method for a display device provided in this disclosure is illustrated, such as... Figure 6 As shown, the method includes the following steps S601-S605.
[0074] Step S601: Determine the inscribed regular polyhedron of the display device. The regular polyhedron includes multiple regular polygonal faces.
[0075] Step S602: Divide each regular polygon face into triangles to obtain multiple congruent main triangles.
[0076] Step S603: Based on the equidistant points on the sides of each main triangle, perform triangular topological partitioning on the main triangle to obtain multiple congruent sub-triangles.
[0077] Step S604: Connect the body center of the regular polyhedron and the vertices of the multiple sub-triangles and extend them to the display device to determine the projection points of the vertices of the multiple sub-triangles on the display device.
[0078] Step S605: Connect the three projection points of each sub-triangle to obtain multiple triangular display units.
[0079] In this embodiment, the regular polygonal face of the inscribed regular polyhedron of the display device is triangularly divided to obtain multiple congruent main triangles. Then, based on the division points on the sides of each main triangle, the main triangle is triangularly topologically divided to obtain multiple congruent sub-triangles, thereby achieving the equal division of the regular polygon. Then, by using spherical projection (i.e., the projection of the line from the body center of the regular polyhedron to the vertex of the sub-triangle and extending to the back of the display device), the structural dimensions of the multiple display units are made closer, and the size of the multiple sub-triangles is reduced, thereby reducing the number of display unit types, reducing the mold opening cost of screen splitting, and reducing the manufacturing difficulty of the display device.
[0080] In this embodiment of the disclosure, the display area of the display device is an irregularly shaped display area, such as a crown-shaped display area or a spherical display area.
[0081] When the display area of the display device is a spherical display area, in some embodiments, step S601 above includes: determining an inscribed regular dodecahedron of the spherical display area, wherein the regular dodecahedron includes twelve regular pentagonal faces. Correspondingly, step S602 above includes: for each regular pentagonal face, connecting the center of the regular pentagonal face to the five vertices of the regular pentagonal face respectively to obtain five congruent principal triangles.
[0082] Thus, in conjunction with the first topological partitioning method described in the above embodiments, it can be seen that in this embodiment, after dividing the regular pentagon into five congruent main triangles, the main triangles are further divided into triangular topological partitions using the division points on their sides, resulting in multiple rings of display units, each ring having the same structural dimensions. When dividing the sides of the triangles equally, the more divisions, the closer the structural dimensions of adjacent rings of display units become, ensuring that the difference in structural dimensions between adjacent rings remains within the tolerance range of the display unit's manufacturing process. This facilitates adjustments to the structural dimensions of one ring of display units within two adjacent rings, further reducing the number of structural dimension variations in the display device and thus lowering the manufacturing complexity of the display device.
[0083] In some other embodiments, step S601 includes: determining an inscribed regular icosahedron of the spherical display area, the regular icosahedron comprising twenty equilateral triangular faces. Correspondingly, step S602 includes: performing triangular topological partitioning on the equilateral triangular faces based on the bisection points on the sides of each equilateral triangular face to obtain four congruent principal triangles.
[0084] Thus, in this embodiment, since the regular icosahedron is the regular polyhedron closest to a sphere, when the display device is divided into screens based on twenty equilateral triangles, the resulting smallest triangle mesh has more uniform geometric properties. That is, the structural dimensions of the multiple display units obtained after screen division are almost the same, thereby reducing the number of structural dimensions of the display units and reducing the manufacturing difficulty of the display device.
[0085] This disclosure also provides another method for screen splitting in a display device. This method includes steps S701-S702.
[0086] Step S701: Determine the inscribed regular polyhedron of the display device. The regular polyhedron includes multiple regular polygonal faces.
[0087] Step S702: Divide each regular polygon face into triangles using sphere center projection to obtain multiple display units with triangular structures.
[0088] In this embodiment of the disclosure, the display area of the display device is an irregularly shaped display area, such as a crown-shaped display area or a spherical display area.
[0089] When the display area of the display device is a spherical display area, in some embodiments, the above step S701 includes: determining the inscribed regular dodecahedron of the spherical display area, wherein the regular dodecahedron includes twelve regular pentagonal faces. Accordingly, step S702 includes: determining the projection of the center of each pentagonal face onto the display device, that is, using the body center of a regular dodecahedron as the center of the sphere to determine the projection point of the center of the pentagonal face onto the display device; then dividing the pentagonal face into five congruent principal triangles based on the projection points corresponding to the five vertices and the center of the face; then bisecting the sides of each principal triangle and determining the projection points of the bisecting points on the display device; then dividing each principal triangle into multiple smaller triangles based on the three vertices and four projection points; then repeating the bisecting operation and the projection point operation of the bisecting points on the display device, using each smaller triangle as the smallest unit, until multiple smallest triangles are obtained based on the four projection points on the display device (the side length of the smallest triangle is slightly greater than 7 cm); then setting display units in the areas corresponding to the smallest triangles to obtain multiple display units.
[0090] Thus, in step S702 above, since each topology division is based on the projection points of the bisection points onto the display device, and the side lengths of multiple smallest triangles are made similar through multiple topology divisions, the structural dimensions of the multiple display units after the display device is divided into screens are more similar. Therefore, in the actual manufacturing of multiple display units, the structural dimensions of the multiple display units of the display device can be set to be exactly the same, thereby reducing the difficulty of the manufacturing process.
[0091] In some embodiments, step S701 includes: determining an inscribed regular icosahedron of the spherical display area, the regular icosahedron comprising twenty equilateral triangular faces. Correspondingly, step S702 includes: bisecting the sides of each equilateral triangular face and determining the projection points of the bisecting points on the display device; then dividing each equilateral triangular face into four principal triangles based on the three vertices and four projection points of the equilateral triangular face; then using each principal triangle as the smallest unit, repeating the above bisecting operation and the operation of the bisecting points projecting onto the display device, until multiple smallest triangles are obtained based on the four projection points on the display device (the side length of the smallest triangle is slightly greater than 7 cm); then setting display units in the areas corresponding to the smallest triangles to obtain multiple display units.
[0092] Thus, in step S702 above, since each topology division is based on the projection points of the bisection points onto the display device, and the side lengths of multiple smallest triangles are made similar through multiple topology divisions, the structural dimensions of the multiple display units after the display device is divided into screens are more similar. Therefore, in the actual manufacturing of multiple display units, the structural dimensions of the multiple display units of the display device can be set to be exactly the same, thereby reducing the difficulty of the manufacturing process.
[0093] It should be noted that although the steps of the screen splitting method of the display device in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that these steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.
