[0039] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is described in further detail below with reference to the drawings and specific embodiments.

[0040] ​Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “a,” “an,” “an,” “the,” and similar words used in this disclosure do not indicate quantity limitation and may indicate singular or plural. The terms “comprising,” “including,” “having,” and any variations thereof used in this disclosure are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or modules (units) is not limited to the listed steps or units, but may also include steps or units not listed, or may include other steps or units inherent to such processes, methods, products, or devices. The terms “connected,” “linked,” “coupled,” and similar words used in this disclosure are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. “Multiple” in this disclosure refers to two or more. “And / or” describes the relationship between related objects, indicating that three relationships may exist; for example, “A and / or B” can indicate: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following objects are in an "or" relationship. The terms "first," "second," "third," etc., used in this disclosure are merely to distinguish similar objects and do not represent a specific ordering of objects. "Above," "below," "left," "right," etc., are only used to indicate relative positional relationships; when the absolute position of the described objects changes, the relative positional relationship may also change accordingly.

[0041] In recent years, immersive spherical video walls have increasingly attracted attention in the entertainment and film industries. Because a standard perfect sphere is a secondary sphere, conventional rigid display substrates cannot be perfectly spliced ​​into a perfect sphere. In some embodiments, the spherical video wall is formed by bending and splicing a series of rectangular light panels. The term "spherical video wall" in this disclosure refers to a video wall that is approximately spherical in shape overall, not necessarily a perfect sphere in the strict sense.

[0042] Figure 1 These are schematic diagrams of the geometric shape of the spherical splicing screen provided in some embodiments, such as... Figure 1 As shown, in the entire spherical splicing screen, all the display substrates 10 have a rectangular quadrilateral shape. These display substrates 10 are usually bent into an approximate arc in the latitude direction (X direction in the figure) to achieve a smooth transition; while they cannot be bent again in the longitude direction (Y direction in the figure), so adjacent display substrates 10 will form an angle in the Y direction. Figure 2 It shows Figure 1 The shape of a row of display substrates 10 in a spherical splicing screen, from... Figure 2It can be seen that the transition between adjacent display substrates 10 is not smooth, but presents a certain angle. Moreover, the sizes of the two adjacent display substrates 10 in the same column are different.

[0043] In the design of the display substrate 10 in this layout, from the top of the spherical tiled screen (the north pole) to the middle of the spherical tiled screen (the equator), there are 90°. In this interval, the more concentrated the number of display substrates 10 is, the larger the angle between adjacent display substrates 10 is, and the smaller the supplementary angle of the angle is, Figure 3 The relationship between the size of the display substrate 10 and the angle is shown, which represents the supplementary angle of the angle between the display substrates 10. It can be seen that when the supplementary angle is 10°, the spherical tiling contains 10 sizes of display substrates 10.

[0044] It should be noted that in the embodiments of the present disclosure, when the face types of two display substrates 10 are not congruent, it means that the sizes of the two display substrates 10 are different.

[0045] It can be seen that for the spherical tiled screen, when the display substrates 10 in quadrilateral are tiled, a large number of sizes of display substrates 10 are required, thereby causing the design of the display substrate 10 to be complex and the overall tiling to be difficult.

[0046] In order to solve the above technical problems, the embodiments of the present disclosure provide a display device, Figure 4 A schematic diagram of the display device provided in some embodiments of the present disclosure is shown, as Figure 4 As shown, the display device includes a plurality of substrate groups 10g, the plurality of substrate groups 10g includes N display substrates 10 tiled with each other, N is an integer greater than 1, and the face type of the display substrate 10 is a triangle. In any two substrate groups 10g, the size of the display substrate 10 in one of the substrate groups 10g corresponds to the size of the display substrate 10 in the other substrate group 10g one by one, that is, the display substrate 10 in one of the substrate groups 10g corresponds to the display substrate 10 in the other substrate group 10g one by one in any two substrate groups 10g, and the two corresponding display substrates 10 are congruent.

[0047] Among them, the plurality of substrate groups 10g constitutes at least part of a polyhedron, and the angle between any two adjacent display substrates 10 in the polyhedron is an obtuse angle.

[0048] In one example, the plurality of substrate groups 10g enclose a closed polyhedron, and the display surface of each display substrate 10 is located on the outer surface of the polyhedron, thereby forming a spherical screen structure; of course, in other examples, the plurality of substrate groups 10g can constitute part of the polyhedron, thereby constituting a semi-spherical screen structure.

[0049] It should be noted that the "face type" of the display substrate 10 in the present disclosure refers to the planar shape defined by the connection of the plurality of vertices of the display substrate 10. The display substrate 10 can be a rigid display substrate 10, and the "face type" of the display substrate 10 is the shape of the display surface of the display substrate 10.

[0050] In the embodiments of the present disclosure, the display substrate 10 can be an LED (Light Emitting Diode) display substrate 10, for example, a Micro-LED display substrate 10 or a Mini-LED display substrate 10.

[0051] In the embodiments of the present disclosure, the face type of the display substrate 10 is a triangle, making the splicing more flexible; and in any two substrate groups 10g, the display substrate 10 of one substrate group 10g corresponds to the display substrate 10 of the other substrate group 10g one by one, and the face types of the corresponding two display substrates 10 are mutually congruent, so that in the entire spliced display device, the size types of the display substrates 10 are at most N, so that display substrates 10 of fewer size types can be used to form a spherical screen display device.

[0052] In some embodiments, in the same substrate group 10g, the face types of at least 5 display substrates 10 are mutually congruent triangles, further reducing the size types of the display substrates 10.

[0053] In some embodiments, the plurality of vertices of each display substrate 10 are located on the same spherical surface, that is, the polyhedron surrounded by the plurality of substrate groups 10g has an inscribed spherical surface, and each vertex of each display substrate 10 is located on the inscribed spherical surface. It should be noted that the display device in the embodiments of the present disclosure allows a certain process error, for example, among all the vertices of the plurality of display substrates 10, a part of the vertices can not be on the above-mentioned inscribed spherical surface, and the distance between these vertices and the inscribed spherical surface is not more than one thousandth of the radius of the inscribed spherical surface, or not more than one thousandth of the radius of the inscribed spherical surface.

[0054] Figure 5 The design principle of the display device provided in some embodiments of the present disclosure is shown in the following figure, Figure 5 The design principle is used for Figure 4 the design process of the display device in the present disclosure. First, as shown in (a) of the figure, Figure 5 a regular dodecahedron structure 2 is designed, and each face of the dodecahedron structure 2 is a regular pentagon. Since each face is the same, only one regular pentagon needs to be geometrically designed to achieve perfect splicing of the entire machine, which greatly simplifies the design process. Then, taking one of the regular pentagonal faces face1 as an example for extension, the vertices of the regular pentagonal face Face1 are respectively denoted as A1-A5; as Figure 5In Figure (b), point O is the center of the circumsphere of the regular dodecahedron 2. Take a point P in space such that the distance between point A1 and point O is equal to the distance between point P and point O, and the distances between point P and point A1, point P and point A2, point P and point A3, point P and point A4, and point P and point A5 are the same. At this point, the lines connecting point P to the five vertices A1 to A5, and the five sides of the pentagon face 1, define five first triangular faces: △PA1A2, △PA2A3, △PA3A4, △PA4A5, and △PA5A1. These five first triangular faces are congruent triangles.

[0055] Following the same method, the remaining 11 faces of the dodecahedron are extended in the same way, ultimately forming... Figure 5 In the hexahedron shown in Figure (c), any two of the first triangular faces are congruent. Among the five first triangular faces extending from the same pentagonal face, the included angle between any two adjacent first triangular faces is 153.8°. For example, the included angle between first triangular faces Face2 and Face3, and the included angle between first triangular faces Face2 and Face4, are both 153.8°. The included angle between any two first triangular faces extending from two adjacent pentagonal faces and positioned adjacently is 161.9°. For example, the included angle between first triangular faces Face2 and Face5 is 161.9°. The average included angle between all the first triangular faces is 22.1°. The aforementioned two adjacent first triangular faces refer to two first triangular faces sharing a single side.

[0056] In one example, it can be followed Figure 5 (c) The first triangular facet in the figure is used to design the display substrate 10. Each first triangular facet in the figure can represent a display substrate 10. After splicing, a display substrate 10 can be obtained. Figure 5 (c) shows a splicing display device with the same structure, where the center O is the center of the circumcircle of the final display device (polyhedron). In this case, five display substrates 10 extending from the same regular pentagonal face constitute a substrate group 10g, and multiple display substrates 10 in the same substrate group 10g are arranged around the center of the substrate group 10g. The faces of any two display substrates 10 in the same substrate group 10g are congruent triangles. When splicing the display substrates 10, considering certain splicing tolerances, in the final display device, the included angle between two adjacent display substrates 10 in the same substrate group 10g is between 153.3° and 154.3°, for example, 153.8°; the included angle between two adjacent display substrates 10 in different substrate groups 10g is between 161.4° and 162.4°, for example, 161.9°.

[0057] Figure 6 The design principle of the display device provided in some embodiments of the present disclosure is shown in FIG. 1A. Figure 6 The hexacontahedron shown in FIG. 1A is expanded on the basis of the dodecahedron in the above embodiment. Taking a first triangular face face2 as an example, M second triangular faces can be further expanded on the basis of the first triangular face face2, M being an integer greater than 1. The M second triangular faces expanded from the second triangular face face2 are in contact with the three vertices (i.e., the first vertex A, the second vertex B, and the third vertex C) of the first triangular face face2, and the remaining positions of the M second triangular faces are located on the side of face2 away from the center O of the circumscribed sphere of the polyhedron.

[0058] For each first triangular face of the hexacontahedron, the same expansion as face2 can be adopted to obtain 60*M second triangular faces, and the size design and splicing of the display substrate 10 are performed according to the size and positional relationship of the 60*M second triangular faces, so that the included angle between the display substrates 10 can be larger, and the visual effect is smoother.

[0059] In some examples, the first triangular face face2 is expanded to obtain a plurality of second triangular faces, as shown in FIG. 1B. Figure 6 In FIG. 1B, ΔAFD, ΔCDE, ΔEFB, and ΔDEF are shown. The positions of D, E, and F satisfy: the distance between O and F is equal to the distance between O and A; the distance between A and F is equal to the distance between F and B; the distance between O and D is equal to the distance between O and A; the distance between A and D is equal to the distance between C and D; the distance between O and E is equal to the distance between O and C; and the distance between E and C is equal to the distance between E and B.

[0060] In some examples, the positions of D, E, and F further satisfy: the line segment OD passes through D', the line segment OE passes through E', and the line segment OF passes through F'.

[0061] In the above manner, the first triangular face face2 is expanded to obtain four second triangular faces, i.e., ΔAFD, ΔCDE, ΔEFB, and ΔDEF. Among the four second triangular faces, ΔAFD and ΔEFB are congruent triangles, and are not congruent with the other two second triangular faces ΔCDE and ΔDEF, and ΔCDE and ΔDEF are not congruent. Therefore, there are three types of sizes of the four second triangular faces.

[0062] The remaining first triangular faces are expanded in the same manner as the expansion of face2 described above, so that Figure 6The 60*4 second triangular faces in the polyhedron in (c) of FIG. 1 have three types of sizes.

[0070] In addition, in the design of the display substrate 10, Figure 6Based on the diagram in (c), after further expansion, ΔAFD corresponds to the first display section, ΔEFB corresponds to the second display section, ΔCDE corresponds to the third display section, and ΔDEF corresponds to the fourth display section. The vertices of the first display section include: the first vertex A, the fourth vertex D, and the sixth vertex F mentioned above.

[0071] exist Figure 6 Based on the expansion of Figure (c), the resulting display substrate 10 has nine different size types. A second angle is formed between each pair of adjacent display substrates 10. The value of each second angle ranges from 173.18 degrees to 175.85 degrees, and the average value of all the second angles is 174.9°. Considering process errors, the average value is between 174.4° and 175.4°.

[0072] After the Figure 6 The expansion of Figure (c) can make the transition between display substrates 10 smoother.

[0073] It should be noted that in practical applications, it is possible to... Figure 7 It can be expanded once based on Figure (c), or it can be expanded many more times.

[0074] Figure 7 This is a schematic diagram of the pixel distribution of the display substrate provided in some embodiments of this disclosure, such as... Figure 8 As shown, in each triangular display substrate, multiple rows of pixels P0 are arranged sequentially from one of the triangle vertices to the opposite side of the triangle; in the direction from the triangle vertices to the opposite side of the triangle, the number of pixels P0 in each row of the triangle increases sequentially, so that each display substrate has as large an area as possible to emit light.

[0075] For example, the display substrate is a Micro-LED substrate or a Mini-LED substrate, and each pixel includes a Micro-LED light-emitting device or a Mini-LED light-emitting device.

[0076] In some embodiments, the row spacing of multiple rows of pixels P0 is the same, that is, the spacing between any two adjacent rows of pixels P0 is a fixed value.

[0077] In some embodiments, the pixel spacing of each row of pixels P0 is not exactly the same.

[0078] In some embodiments, at least one row of pixels P0 is staggered with the row above P0, or at least one row of pixels P0 is staggered with the row below P0, or at least one row of pixels P0 is staggered with both the row above P0 and the row below P0. Wherein, the "staggered" refers to that each pixel P0 in one row is arranged opposite to the interval area between two adjacent pixels P0 in the other row.

[0079] Figure 9 For the relationship diagram between the size category of the display substrate 10 and the angle in different embodiments, the horizontal axis represents the size category of the display substrate 10, and the angle of the vertical axis represents the average value of the complementary angle between the display substrates. It can be seen that, compared with the design of the quadrilateral display substrate 10, the design of the triangular display substrate 10 in the embodiments of the present disclosure can use fewer categories to make the angle between the display substrates 10 larger, thereby realizing the smooth transition in vision, and further simplifying the design and manufacturing difficulty.

[0080] In the above embodiments, each display substrate 10 can be a triangular independent lamp plate; or each display substrate 10 can be divided in the plane to divide it into a plurality of face-type congruent and mutually spliced sub- substrates 11. Figure 9 For the division schematic diagram of the display substrate 10 provided in some embodiments of the present disclosure, as shown in (a) of FIG. 1, Figure 9 each display substrate 10 includes 4 sub- substrates 11 that are mutually spliced and located in the same plane, the face type of the 4 sub- substrates 11 is triangular, and they are mutually congruent; or, as shown in (b) of FIG. 1, ​ each display substrate 10 includes 9 sub- substrates 11 that are mutually spliced and located in the same plane, the face type of the 9 sub- substrates 11 is triangular, and they are mutually congruent. Of course, the display substrate 10 can be further divided into more sub- substrates 11 that are face-type congruent and mutually spliced by the same method.

[0081] When the display substrate 10 includes a plurality of face-type congruent sub- substrates 11, in the entire display device, the category of the sub- substrate 11 is the same as that of the display substrate 10 before division, and since the area of the sub- substrate 11 is smaller than that of the display substrate 10, it is more convenient for manufacturing and installation.

[0082] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the present disclosure, and the present disclosure is not limited thereto. Various modifications and improvements can be made by those skilled in the art without departing from the spirit and essence of the present disclosure, and these modifications and improvements are also considered as the protection scope of the present disclosure.
