[0050] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the embodiments of the present disclosure generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present disclosure.

[0051] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one", "one" or "the" do not indicate quantity restrictions, but indicate that there is at least one. Similar words such as "include" or "comprise" mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Similar words such as "connect" or "connected" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0052] The "multiple or several" mentioned in this disclosure refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0053] In the related art, Figure 1a This is a schematic diagram of the assembly breakdown of an existing curved spliced ​​display screen. Figure 1b for Figure 1a Schematic diagram of the gasket, such as Figure 1a and Figure 1b As shown, the arc-shaped splicing display screen is usually spliced ​​in the following way: by adding a gasket 02 between adjacent display screens 01, and then using a connecting piece 03 to achieve arc-shaped seamless splicing of adjacent display screens 01, the connecting piece 03 is movably connected to a bracket (not shown in the figure), and the bracket is used to support the whole splicing display screen. Furthermore, due to the influence of the processing accuracy of the gasket 02 and the influence of actual operation errors, it is currently necessary to use the curvature of the on-site bracket to control the overall curvature of the spliced ​​display screen.

[0054] For the gaskets 02 and connecting pieces 03 that splice the same group of adjacent display screens 01, in order to achieve a better installation effect, the compensation angle of the gasket 02 and the arc angle of the connecting piece 03 need to be matched one by one; the gaskets 02 used to splice different groups of adjacent display screens 01 have a small compensation angle deviation; the connecting pieces 03 used to splice different groups of adjacent display screens 01 have a small arc angle deviation. Therefore, during on-site installation, the degrees of a large number of gaskets 02 and a large number of connecting pieces 03 that are separately set are easy to be confused, which can easily cause splicing degree deviation, making installation difficult, affecting installation accuracy and efficiency, and seriously failing to achieve seamless splicing, affecting display effects; at the same time, the gaskets 02 and connecting pieces 03 are processed separately, and the processing cost is high; in addition, the curvature of the on-site bracket will also cause a deviation in the curvature of the entire machine, causing extrusion damage between the display screens 01.

[0055] In view of this, the embodiment of the present disclosure provides a connection structure, which is applied to the splicing of display screens to install arc-shaped spliced ​​display screens. The connection structure substantially integrates the gasket and the connecting sheet into one, that is, the connection structure includes a connecting sheet and a gasket connected together, and the thickness of the gasket decreases monotonically in the direction away from the connecting sheet. In this way, in the subsequent display screen splicing process, the gasket is used to adjust the deflection angle between the mutually spliced ​​display screens, thereby realizing the arc splicing of the display screens. The embodiment of the present disclosure designs a connection structure that integrates the gasket and the connecting sheet into one. Compared with the traditional method of separating the gasket and the connecting sheet, it avoids the matching of parts during on-site installation, simplifies the installation difficulty, and improves the installation efficiency.

[0056] The connection structure provided in the embodiment of the present disclosure is applied to the splicing of display screens to install a spliced ​​display screen that forms an arc. The spliced ​​display screen is a large-size display device, and the arc-shaped spliced ​​display screen is conducive to improving the visual experience of viewers.

[0057] Figure 2a A schematic diagram of a connection structure provided in an embodiment of the present disclosure, Figure 2b A top view of a connection structure provided in an embodiment of the present disclosure, Figure 2c A left side view of the connection structure provided by the embodiment of the present disclosure, Figure 2d A front view of the connection structure provided in the embodiment of the present disclosure, such as Figure 2a to Figure 2d As shown, the connection structure 100 includes a connecting sheet 1 and a gasket 2 that are interconnected, wherein the connecting sheet 1 has a first mounting area Q1, a second mounting area Q2, and a connecting area Q3 located between the first mounting area Q1 and the second mounting area Q2; the first mounting area Q1, the second mounting area Q2, and the connecting area Q3 are arranged side by side in a first direction X; the gasket 2 is arranged in the connecting area Q3 and is connected to the connecting sheet 1; the shape of the positive projection of the gasket 2 on the connecting sheet 1 is a strip extending along the second direction Y; the first direction X and the second direction Y are arranged crosswise.

[0058] Optionally, the surface where the gasket 2 is connected to the connecting piece 1 is a reference surface. The connecting piece 1 is a plate-like structure, and the outline of the orthographic projection of the connecting piece 1 on the reference surface is approximately rectangular. The first direction X is the length direction of the connecting piece 1, and the second direction Y is the width direction of the connecting piece 1.

[0059] Optionally, the gasket 2 is a plate-like structure. Figure 2b to Figure 2d As shown, the direction in which the gasket 2 is away from the connecting sheet 1 is the thickness direction of the connecting sheet 1, that is, the third direction Z, and the gasket 2 extends in the direction away from the connecting sheet 1. The size of the gasket 2 in the third direction Z is the height of the gasket 2. The size of the gasket 2 in the first direction X is the thickness of the gasket 2. The size of the gasket 2 in the second direction Y is the width of the gasket 2.

[0060] Alternatively, if Figure 2b As shown, the first mounting area Q1 and the second mounting area Q2 have the same shape and size, and the area of ​​the first mounting area Q1 (or the second mounting area Q2) is larger than the area of ​​the connection area Q3. The size of the first mounting area Q1 (or the second mounting area Q2) in the first direction X is larger than the size of the connection area Q3 in the first direction X, and the size of the first mounting area Q1 (or the second mounting area Q2) in the second direction Y is equal to the size of the connection area Q3 in the first direction X.

[0061] During the assembly stage, the connecting piece 1 is used to realize the splicing of two adjacent display screens. Specifically, the part of the connecting piece 1 located in the first installation area Q1 is flexibly connected to a first display screen 011, and the part of the connecting piece 1 located in the second installation area Q2 is flexibly connected to another second display screen 012, thereby realizing the splicing of two adjacent display screens.

[0062] In addition, the gasket 2 is located between the first display screen 011 and the second display screen 012, and the thickness of the gasket 2 decreases monotonically in the direction away from the connecting plate 1, and is used to adjust the deflection angle γ between the first display screen 011 and the second display screen 012, thereby realizing arc splicing of the display screens.

[0063] In some embodiments, Figure 2a to Figure 2d As shown, the connecting piece 1 and the gasket 2 are connected as an integral structure, and the compensation angle α of the gasket 2 and the arc angle θ (for example, α / 2) of the connecting piece 1 can be matched by one-time finishing, thereby ensuring the splicing accuracy and improving the product yield. This solves the problems of many types of gaskets 2 and connecting pieces 1, difficult matching, and high processing costs, and greatly improves market competitiveness.

[0064] The blank structure 200 of the connection structure 100 of the present disclosure can be formed by integral die casting using a mold. Figure 3 A schematic diagram of a blank structure formed in the pre-processing stage of the connection structure provided in an embodiment of the present disclosure, such as Figure 3As shown, the blank structure 200 includes a semi-finished connecting sheet 10 and a semi-finished gasket 20. Specifically, a die-casting plate is provided, and then the specific size of the blank structure 200 can be determined according to the size of the display screen to be spliced ​​in the arc-shaped spliced ​​display screen, and the blank structure 200 can be produced by a one-time die of the die-casting plate as a semi-finished product of the connection structure 100 for standby. Afterwards, according to the curvature requirements of the arc-shaped spliced ​​display screen and the specific number of display screens to be spliced ​​in the arc-shaped spliced ​​display screen, the blank structure 200 is finely processed (for example, digitally controlled precision machining, i.e., CNC fine machining) to form a connection structure 100 that meets different curvature requirements, such as Figure 2a to Figure 2d As shown, this greatly reduces Figure 1a The types of accessories of the connecting piece 03 and the gasket 02 shown improve the adaptability of the accessories; at the same time, the die-casting and CNC processing cycles involved in this preparation process are short, and the connecting structure 100 has high manufacturing efficiency and low cost, which solves the problems of high processing cost, long cycle and poor effect of different structural parts caused by the separate structure of the gasket 02 and the connecting piece 03 in the prior art.

[0065] In some embodiments, Figure 4 for Figure 2d A partial enlarged view of the gasket shown, such as Figure 4 As shown, the gasket 2 includes a first surface 21 and a second surface 22 disposed opposite to each other along the thickness direction thereof, and the dihedral angle formed by the extended surface of the first surface 21 and the extended surface of the second surface 22 is α. Figure 4 The extension process of the first surface 21 and the second surface 22 is omitted, and only the dihedral angle α finally formed is shown. Figure 4 The dotted part in .

[0066] The angle range of α is between 0 and 2°, excluding 0. For example, α=0.8°, α=1°, α=1.5° or α=2°. α is recorded as the compensation angle between the display screens to be spliced. The actual value of α can be set according to the curvature requirement of the arc spliced ​​display screen, and the present disclosure does not make an absolute limitation on this.

[0067] The dihedral angle α formed by the extended surface of the first surface 21 and the extended surface of the second surface 22, that is, the first display screen 011 and the second display screen 012 in the spliced ​​display screen (see Figure 7 For example, the first display screen 011 is rotated counterclockwise by an angle α relative to the second display screen 012 with one of the adjacent sides of the first display screen 011 being the connecting axis; or the second display screen 012 is rotated clockwise by an angle α relative to the first display screen 011 with one of the adjacent sides of the first display screen 011 being the connecting axis.

[0068] In some embodiments, Figure 2dAs shown, the contour shape of the orthographic projection of the gasket 2 on the XOZ reference plane is an isosceles trapezoid.

[0069] In some embodiments, the gasket 2 may be a wedge-shaped structure. For example, the contour shape of the orthographic projection of the gasket 2 on the XOZ reference plane is a right-angled trapezoid.

[0070] In some embodiments, Figure 4 As shown, the gasket 2 also includes a third surface 23 in contact with the connecting sheet 1; the angle of the dihedral angle formed between the first surface 21 and the third surface 23 is a first angle β1, and the angle of the dihedral angle formed between the second surface 22 and the third surface 23 is a second angle β2; the first angle β1 is the same as the second angle β2, that is, the inclination angles of the first surface 21 and the second surface 22 are the same, which is conducive to making the splicing arc of the spliced ​​display screen formed by the subsequent multiple display screens smoother, improving the uniformity of the splicing strength of the display screen, improving the splicing reliability, ensuring the display effect of the arc splicing, and improving the picture quality.

[0071] Exemplarily, the first angle β1 is the complementary angle of half the included angle α, that is, α=1°, then the first angle β1=85.5°, and the second angle β2=85.5°.

[0072] In some embodiments, Figure 2d As shown, the connecting sheet 1 includes a first connecting portion 11 located in the first installation area Q1 and a second connecting portion 12 located in the second installation area Q2; the first connecting portion 11 includes a fourth surface 11a connected to the first surface 21, and the second connecting portion 12 includes a fifth surface 12a connected to the second surface 22. The fourth surface 11a and the first surface 21 are perpendicular to each other, and the fifth surface 12a and the second surface 22 are perpendicular to each other, which means that during the installation stage, the fourth surface 11a is perpendicular to the first display screen 011 (such as Figure 7 The fifth surface 12a is parallel to the display surface of the second display screen 012 (as shown in FIG. Figure 7 The display surfaces of the display panels are parallel to each other (as shown in the figure), so the connecting sheet 1 and the gasket 2 work together to ensure the curvature of the whole machine of the spliced ​​display screen, improve the reliability of the curvature splicing, ensure the display effect of the arc splicing, and improve the image quality. In addition, this design does not need to use the bracket 8 to control the curvature of the whole machine. This embodiment reduces the design requirements for the bracket 8, solves the deviation effect of the traditional bracket 8 on the curvature of the whole machine, and avoids squeezing damage between the display screens.

[0073] In some embodiments, Figure 2d As shown, the thickness of the first connection portion 11 decreases monotonically along the direction approaching the second connection portion 12 ; and the thickness of the second connection portion 12 decreases monotonically along the direction approaching the first connection portion 11 .

[0074] Alternatively, if Figure 2dAs shown, the first connection portion 11 further includes a sixth surface 11 b away from the gasket 2 , and the second connection portion 12 further includes a seventh surface 12 b away from the gasket 2 ; the sixth surface 11 b and the seventh surface 12 b are coplanar.

[0075] In some embodiments, Figure 2b As shown, the surface where the gasket 2 is connected to the connecting piece 1 is a reference surface; a first center line L1 of the orthographic projection of the gasket 2 on the reference surface extending along the second direction Y is colinear with a second center line L2 of the orthographic projection of the connecting piece 1 on the reference surface extending along the second direction Y, so that the structure of the connecting piece 1 located on both sides of the gasket 2 in the first direction X (that is, the first connecting portion 11 and the second connecting portion 12) is evenly distributed, thereby improving the consistency and reliability of the installation strength of the connecting piece 1 and the display screen, ensuring the display effect of the arc splicing, and improving the picture quality.

[0076] In some embodiments, Figure 2b As shown, the ratio of the size of the gasket 2 in the first direction X to the size of the connecting piece 1 in the first direction X is between 1:150 and 1:35.

[0077] For example, Figure 2b and Figure 2c As shown, the dimension of the connecting piece 1 in the first direction X (that is, the length of the connecting piece 1) is 150 mm, the dimension of the connecting piece 1 in the second direction Y (that is, the width of the connecting piece 1) is 67.5 mm, and the dimension of the connecting piece 1 in the third direction Z (that is, the thickness of the connecting piece 1) is 15 mm.

[0078] For example, the height of the gasket 2 is determined according to the box 01a of the display screen 01 (e.g. Figure 7 For example, the thickness of the box 01a of the display screen 01 is 37 mm, so the height of the gasket 2 is set to be less than 37 mm. Further, in order to ensure that the arc angle can be formed between adjacent display screens and reduce the joint between the display surfaces (i.e., light emitting surfaces) of adjacent display screens, the height of the gasket 2 is set to 35 mm.

[0079] Exemplarily, the thickness of the gasket 2 is adjusted according to the curvature requirement of the curved spliced ​​display screen, and the maximum thickness of the gasket 2 is between 3 mm and 5 mm.

[0080] In some embodiments, Figure 2b As shown, the maximum dimension of the gasket 2 in the second direction Y is the same as the maximum dimension of the connecting piece 1 in the second direction Y. That is, the width of the gasket 2 is set to occupy the entire width of the connecting piece 1, thereby improving the splicing reliability of the spliced ​​display screen, ensuring the display effect of the arc splicing, and improving the image quality; at the same time, the connection strength between the connection structure 100 and the display screen is improved.

[0081] In some embodiments, Figure 2c and Figure 2d As shown, the gasket 2 includes a first surface 21 and a second surface 22 arranged opposite to each other along its thickness direction (i.e., the first direction X), a first side surface 24 and a second side surface 25 arranged opposite to each other along the second direction Y and connecting the first surface 21 and the second surface 22, and a third side surface 26 connecting the first side surface 24 and the second side surface 25 and away from the side of the connecting piece 1, the dihedral angle formed by the first side surface 24 and the third side surface 26 is a rounded angle, and the dihedral angle formed by the second side surface 25 and the third side surface 26 is a rounded angle.

[0082] The first surface 21 and the second surface 22 have the same outer contour shape, including but not limited to any one of a quadrilateral, a pentagon, a hexagon, an octagon, a semicircle, and a triangle. It should be noted that the outer contour shape of the first surface 21 and the second surface 22 mentioned here refers to the shape ignoring the rounded corners.

[0083] Figure 5a to Figure 5c Schematic diagram of gaskets of various shapes provided in the embodiment of the present disclosure. The contour shape of the first surface 21 is a quadrilateral, such as a rectangle. Figure 5a As shown; another example is a trapezoid, such as Figure 5b The first surface 21 is arched, as shown. Figure 5c shown.

[0084] In some embodiments, the material of the connection structure 100 may be selected from but is not limited to metal materials and alloys, such as aluminum.

[0085] In addition, the embodiment of the present disclosure further provides a spliced ​​display screen. Figure 6 A schematic diagram of the display surface side of the entire spliced ​​display screen provided in an embodiment of the present disclosure, Figure 7 A schematic diagram of a splicing structure of a display screen provided in an embodiment of the present disclosure, such as Figure 6 and Figure 7 As shown, the spliced ​​display screen specifically includes a connection structure 100 provided in any of the above embodiments and a plurality of display screens 01. Adjacent display screens 01 (eg, a first display screen 011 and a second display screen 012) are spliced ​​into an arc shape through the connection structure 100.

[0086] The spliced ​​display screen provided in the embodiment of the present disclosure is a large-size display device, and the curved spliced ​​display screen is beneficial to improving the visual experience of the viewer.

[0087] It should be noted that different groups of mutually spliced ​​display screens 01 may use connection structures 100 with different compensation angles α to meet arc splicing requirements.

[0088] In some embodiments, Figure 6 and Figure 7As shown, the spliced ​​display screen includes a plurality of display screens 01 arranged in an array; the plurality of display screens 01 include a first display screen 011 and a second display screen 012 adjacent to each other in a row direction X1.

[0089] like Figure 7 As shown, a gasket 2 is sandwiched between the first display screen 011 and the second display screen 012, and the thickness of the gasket 2 decreases monotonically along the direction away from the connecting sheet 1, and the first surface 21 (as shown in FIG. Figure 4 as shown) and a second surface 22 (as shown Figure 4 The tilt setting as shown is used to adjust the deflection angle γ between the first display screen 011 and the second display screen 012, thereby realizing the arc splicing of the display screen 01.

[0090] The gasket 2 includes a first surface 21 and a second surface 22 which are arranged opposite to each other along its thickness direction (first direction X); the first surface 21 contacts the first display screen 011, and the second surface 22 contacts the second display screen 012; the dihedral angle formed by the extended surface of the first surface 21 and the extended surface of the second surface 22 is a deflection angle γ of the first display screen 011 relative to the second display screen 012, and the range of the deflection angle γ is between 0 and 2°, and does not include 0.

[0091] It should be noted that the deflection angle γ here is a relative concept, not an absolute concept, and specifically refers to the angle after the first display screen 011 rotates clockwise about a fixed axis relative to the second display screen 012. The fixed axis here can be the connecting axis between the first display screen 011 and the second display screen 012. Of course, the deflection angle γ can also refer to the angle after the second display screen 012 rotates counterclockwise about the fixed axis relative to the first display screen 011.

[0092] It should be noted that the deflection angle γ can be set according to the curvature requirement of the arc-shaped spliced ​​display screen, and the present disclosure does not impose an absolute limitation on this. The deflection angle γ is equal to the included angle α between the extended surface of the first surface 21 and the extended surface of the second surface 22 .

[0093] In some embodiments, for multiple groups of first display screens 011 and second display screens 012 in the column direction Y1, the deflection angle γ of each group of first display screens 011 relative to the second display screen 012 is the same, which is beneficial to improving the flatness of the arc-shaped splicing of the display screens 01, ensuring the smooth arc of the spliced ​​display screens 01, improving the uniformity of the splicing strength of the display screens 01, improving the splicing reliability, and facilitating improving the display quality.

[0094] In some embodiments, Figure 2d and Figure 7As shown, the connecting piece 1 includes a first connecting portion 11 located in the first installation area Q1 and a second connecting portion 12 located in the second installation area Q2; the first connecting portion 11 is movably connected to the first display screen 011, and the second connecting portion 12 is movably connected to the second display screen 012; the first connecting portion 11 includes a fourth surface 11a close to the first display screen 011, and the second connecting portion 12 includes a fifth surface 12a close to the second display screen 012; the fourth surface 11a is connected to the first surface 21, and the fifth surface 12a is connected to the second surface 22; the fourth surface 11a is parallel to the display surface AA1 of the first display screen 011, and the fifth surface 12a is parallel to the display surface AA2 of the second display screen 012, so that the connecting piece 1 and the gasket 2 work together to ensure the curvature of the whole machine of the spliced ​​display screen, and improve the reliability of the curvature splicing; in this way, there is no need to use the bracket 8 to control the curvature of the whole machine. This embodiment reduces the design requirements for the bracket 8, solves the deviation influence of the traditional bracket 8 on the curvature of the whole machine, and avoids extrusion damage between the display screens 01.

For example, the front mounting hole V1 can be an M6 threaded hole; the minimum size of the rear mounting hole V2 is greater than 7mm, and the maximum size is between 12mm and 15mm.

[0101] In some embodiments, Figure 8a and Figure 8b As shown, the surface where the gasket 2 is connected to the connecting piece 1 is the reference surface; the first mounting hole 31 and the second mounting hole 41 are arranged in a one-to-one correspondence, and the correspondingly arranged first mounting holes 31 and the second mounting holes 41 are symmetrically arranged with the second center line L2 as the symmetry axis; the second center line L2 is the center line of the orthographic projection of the connecting piece 1 on the reference surface extending along the second direction Y, ensuring that the inclination angles and positions of the adjacent first display screen 011 and the second display screen 012 are symmetrical, which is beneficial to improving the flatness and smoothness of the arc splicing of the display screen 01, ensuring the uniformity of the splicing strength of the display screen 01, and the splicing reliability, which is beneficial to improving the display quality.

[0103] In this embodiment, the connection structure 100 can simultaneously splice two groups of adjacent display screens 01 (four display screens 01). Compared with single-group splicing, it can reduce the risk of alignment deviation, thereby ensuring splicing accuracy and improving splicing reliability; at the same time, it improves splicing efficiency.

The fourth connecting component 6 includes but is not limited to connecting parts such as screws, bolts, studs, bolts, and pins.

[0106] Optionally, the opening H is a through hole, not a threaded hole. The fourth connecting member 6 is a screw (size M6), and the minimum dimension of the opening H in the second direction Y is greater than 7 mm. The minimum dimension of the opening H in the third direction Z is greater than or equal to the distance from the point on the fourth connecting member 6 farthest from the connecting sheet 1 to the connecting sheet 1, for example, between 25 mm and 30 mm.

[0107] like Fig. 9 As shown, the first display screen 011 includes a first side wall 011a close to the second display screen 012 spliced ​​therewith, and the second display screen 012 includes a second side wall 012a close to the first display screen 011 spliced ​​therewith, a threaded hole is provided on the first side wall 011a, and a screw (fourth connecting component 6) is provided on the second side wall 012a, and the screw 6 passes through an opening H on the gasket 2 and is matched with the threaded hole.

[0108] Alternatively, if Figure 2cAs shown, the two openings H are symmetrically arranged with the fourth center line L4 as a symmetry axis. The fourth center line L4 is the center line of the gasket 2 extending along the third direction Z.

The third connecting component 7 passes through the housing of the bracket 8 from the side of the bracket 8 away from the connecting plate 1 and is matched and connected with the third mounting hole V3 on the connecting plate 1.

[0111] The same bracket 8 is used to connect the connection structure 100 between the first display screen 011 and the second display screen 012 which are spliced ​​together in each row in two adjacent columns.

[0112] Optionally, the spliced ​​display screen includes: Figure 8a The connecting mechanism 100 corresponding to the connecting piece 1 shown in FIG. Figure 8b The connecting sheet 1 shown corresponds to the connecting mechanism 100 and the plurality of display screens 01.

Figure 8b The connecting mechanisms 100 corresponding to the connecting pieces 1 shown are respectively spliced ​​with the display screens 01 to form an arc-shaped spliced ​​display screen.

[0113] In some embodiments, the spliced ​​display screen may be a Mini LED display screen or a Micro LED display screen. Among them, the Mini LED display screen refers to a light emitting diode chip (LED) with a grain size (LED chip size) of about 100 microns to 300 microns. Micro LED refers to an LED chip with a grain size of less than 100 microns. Mini LED display screens or Micro LED display screens can be used as self-luminous LED displays, and have the advantages of low power consumption, high brightness, high resolution, high color saturation, fast response speed, long life, and high efficiency. In particular, Mini LED display screens and Micro LED display screens can be seamlessly spliced ​​through unit display modules (that is, the first display screen 011 and the second display screen 012) to achieve ultra-large screen display, and have broad application prospects in large-size display fields such as professional display, commercial display, rental display, sports display, and creative display.

The connection structure 100 provided in the embodiment of the present disclosure is used to realize the whole machine splicing, which reduces the installation error rate, reduces the cost and has a simple structural design, while effectively improving the installation efficiency, reducing the installation difficulty, and ensuring the display effect of the arc splicing.

[0115] In some embodiments, the spliced ​​display screen can be a P1.25 Mini LED COB spliced ​​display product. P1.25 means that the spacing between adjacent LEDs is 125 microns, which realizes a small-pitch Mini LED COB spliced ​​display product with higher display brightness and more delicate display effects. The connection structure 100 provided in the embodiment of the present disclosure is used to realize the whole machine splicing, which solves the problems of difficulty in arc splicing, low splicing image quality, and low yield due to the particularity of the light board module and the display screen 01 box 01a.

[0116] In some embodiments, the substrate of the display screen may be a PCB substrate. The connection structure 100 provided in the embodiment of the present disclosure is used to realize the whole machine splicing, and the requirements of low cost, high quality and high efficiency of PCB-based display products are met.

[0117] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present disclosure, but the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and substance of the present disclosure, and these modifications and improvements are also considered to be within the scope of protection of the present disclosure.
