DETAILED DESCRIPTION

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0062] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0063] The special-shaped splicing screen is also called the creative display screen. Compared with the traditional display screen, it has a better visual experience. Its appearance breaks the limitation of the rectangular shape of the traditional display screen. It is no longer limited to the rectangular appearance of the conventional splicing screen, but appears in various splicing shapes. The main feature of the special-shaped splicing screen is that it can better adapt to the overall structure and environment of the building, and the size and dimensions of the screen can be customized according to requirements. In other words, the special-shaped splicing screen can change various shapes to present different effects, making the special-shaped splicing screen more novel and unique in appearance, and more creative in display.

[0064] Since the appearance of each special-shaped unit display screen of the special-shaped splicing screen is different and the structure may be different from each other, the production technology of the manufacturer is required. If the manufacturer's technology is not up to standard, the special-shaped splicing screen made up of various special-shaped unit display screens will inevitably have uneven appearance defects such as too large splicing gaps and discontinuous splicing surfaces, which will affect the viewing effect of the special-shaped splicing screen and destroy the overall design beauty of the special-shaped splicing screen; at the same time, the splicing design between different special-shaped unit display screens is complex and the assembly difficulty is high, which puts higher requirements on the design ability and assembly accuracy of the manufacturer, and will inevitably lead to higher costs for special-shaped splicing screens.

[0065] In the related art, the flat splicing screen adopts frame splicing, fixes the flat unit display screens in independent frames respectively, and then splices multiple frames together. This splicing method has the defects of complex assembly and low assembly efficiency. After the frame is assembled, it is difficult to effectively adjust the splicing state of each flat unit display screen. In addition, this frame is mostly made of metal materials, and uses a lot of materials, resulting in a heavy frame and high cost. If the special-shaped splicing screen also adopts this frame splicing method, the assembly is difficult and it is difficult to ensure the splicing display effect of the special-shaped splicing screen.

[0066] Aiming at the technical problems that the splicing of special-shaped screens using traditional frame splicing is difficult to assemble and difficult to ensure the splicing display effect of special-shaped splicing screens, the embodiment of the present application proposes a special-shaped screen splicing bracket, such as Figures 1 to 20 As shown, the special-shaped screen splicing bracket is used to fix the special-shaped splicing screen, which at least includes a first unit display screen 1000 and a second unit display screen 2000 spliced ​​in a first direction F1, and at least the first unit display screen 1000 is a special-shaped unit display screen; the special-shaped screen splicing bracket at least includes a first fixing part 100 and a second fixing part 200 connected to the first fixing part 100 in the first direction F1, the first fixing part 100 is used to fix the first unit display screen 1000, the second fixing part 200 is used to fix the second unit display screen 2000, and the first fixing part 100 and the second fixing part 200 are located in different planes.

[0067] The special-shaped screen splicing bracket proposed in the embodiment of the present application is as follows: Figures 1 to 20 As shown, the first fixing part 100 and the second fixing part 200 are connected as an integral structure, and the first fixing part 100 and the second fixing part 200 are located in different planes. When the first unit display screen 1000 and the second unit display screen 2000 of the special-shaped splicing screen are assembled on the special-shaped screen splicing bracket, the first unit display screen 1000 and the second unit display screen 2000 can be supported respectively by the first fixing part 100 and the second fixing part 200 to form a whole for support or suspension, which can achieve the purpose of reducing the difficulty of assembling the special-shaped splicing screen; at the same time, according to the structural parameters of the special-shaped splicing screen, the first fixing part 100 and the second fixing part 200 are arranged in different planes, which can adapt to the structural changes of each unit display screen of the special-shaped splicing screen, so that when the first unit display screen 1000 and the second unit display screen 2000 are assembled on the special-shaped screen splicing bracket, it is convenient to adjust the splicing gap to reduce the splicing gap, and at the same time ensure that the splicing gap is flush to form a continuous splicing display surface.

[0068] In some embodiments of the present application, the special-shaped splicing bracket of the special-shaped screen can include two or more unit display screens, and at least one special-shaped unit display screen. Figures 16 to 19As shown, the special-shaped splicing screen may include a special-shaped unit display screen and a flat unit display screen, and the special-shaped unit display screen and the flat unit display screen are fixed on the first fixing part 100 and the second fixing part 200 respectively. The special-shaped unit display screen and the flat unit display screen are positioned and fixed by the first fixing part 100 and the second fixing part 200, so that the splicing gap between the special-shaped unit display screen and the flat unit display screen can be reduced, and the display surface between the special-shaped unit display screen and the flat unit display screen can be continuous. Optionally, the special-shaped splicing screen may include two special-shaped unit display screens, and the structures of the two special-shaped unit display screens may be the same or different. For example, Fig. 20 As shown, the two special-shaped unit display screens can both be two concave curved display screens; the two special-shaped unit display screens can also be two convex curved display screens; as shown Figure 5 As shown, the two special-shaped unit display screens can also be a concave curved display screen and a convex curved display screen, and the two special-shaped unit display screens can be fixed on the first fixing part 100 and the second fixing part 200 respectively. The first fixing part 100 and the second fixing part 200 complete the positioning and fixing of the two special-shaped unit display screens, which can reduce the splicing gap of the two special-shaped unit display screens and ensure the continuity of the display surface between the two special-shaped unit display screens. Optionally, the special-shaped splicing screen can include more than two unit display screens, one unit display screen, two unit display screens or more than two unit display screens can be special-shaped unit display screens. Accordingly, the special-shaped screen splicing bracket can be provided with fixing parts corresponding to the number of unit display screens, and each fixing part is connected as an integral structure, and each fixing part can be located in different planes according to the structure of each unit display screen to adapt to the structural changes of each unit display screen, so that after each unit display screen is positioned and fixed by the corresponding fixing part, the splicing gap can be reduced, and the display surface between each spliced ​​unit display screen can be continuous, thereby ensuring the splicing display effect of the special-shaped splicing screen, and can reduce the preparation accuracy and assembly difficulty of the special-shaped splicing screen.

[0069] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 20As shown, the first fixing part 100, the second fixing part 200 and other fixing part brackets for fixing each unit display screen are interconnected to form an integrated structure. On the one hand, the position of the fixing part is preset according to the structural changes and sizes of each unit display screen, so that each unit display screen can be accurately positioned, which is convenient for two or more unit display screens to be assembled and fixed through the special-shaped splicing bracket. In other words, only one special-shaped screen splicing bracket can be used to solve the splicing assembly of special-shaped splicing screens including at least one special-shaped unit display screen, which can significantly reduce the difficulty of assembling special-shaped splicing screens, improve assembly efficiency, and reduce assembly labor costs; and compared with the traditional method of splicing and assembling using multiple independent splicing frames, the special-shaped screen splicing bracket of the embodiment of the present application can also reduce the amount of materials used and reduce the assembly material cost of the special-shaped splicing screen.

[0070] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figure 1 to Figure 2 , Figure 14 to Figure 15 As shown, the first fixing part 100 may be provided with more than two first fixing holes 110, and the fixing screws 800 are passed through the first fixing holes 110 to connect with the first unit display screen 1000, thereby fixing the first unit display screen 1000 on the first fixing part 100. Optionally, the first fixing part 100 may be provided with two, three or four first fixing holes 110. For example, the first fixing part 100 may be provided with two first fixing holes 110, and the two first fixing holes 110 may be arranged on the first fixing part 100 along the first direction F1; for another example, the first fixing part 100 may be provided with three first fixing holes 110, and the three first fixing holes 110 may be arranged on the first fixing part 100 along the first direction F1 or arranged on the first fixing part 100 in a triangular shape; for another example, the first fixing part 100 may be provided with four first fixing holes 110, and the four first fixing holes 110 may be arranged on the first fixing part 100 along the first direction F1 or arranged on the first fixing part 100 in a quadrilateral shape. Similarly, the second fixing portion 200 may be provided with two or more second fixing holes 210, and the fixing screws 800 are passed through the second fixing holes 210 to connect with the second unit display screen 2000, thereby fixing the second unit display screen 2000 on the second fixing portion 200. The number of the second fixing holes 210 and their arrangement on the second fixing portion 200 are the same as those of the first fixing holes 110, and are not described in detail herein.

[0071] In the special-shaped screen splicing bracket of some embodiments of the present application, the first unit display screen 1000 can be fixedly connected by fixing screws 800 to the fixed rear shell 1100 of the first unit display screen and the first fixed part 100, so that the first unit display screen 1000 is positioned and fixed on the special-shaped screen splicing bracket; the second unit display screen 2000 can be fixedly connected by fixing screws 800 to the fixed rear shell 2100 of the second unit display screen and the second fixed part 200, so that the second unit display screen 2000 is positioned and fixed on the special-shaped screen splicing bracket.

[0072] As an optional implementation, Figures 1 to 20 As shown, the special-shaped screen splicing bracket also includes a step connection part 300, which is connected between the first fixing part 100 and the second fixing part 200, so that there is a splicing height difference D between the first fixing part 100 and the second fixing part 200 in the second direction F2, and the second direction F2 is perpendicular to the first direction F1.

[0073] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 20 As shown, the first fixing part 100 and the second fixing part 200 can be connected together by the step connection part 300 to form an integrated structure, and at the same time, the first fixing part 100 and the second fixing part 200 have a splicing height difference D in the second direction F2 through the step connection part 300, and the structural changes between the first unit display screen 1000 and the second unit display screen 2000 are adapted by the splicing height difference D, so that the first unit display screen 1000 and the second unit display screen 2000 are constrained and fixed by the special-shaped screen splicing bracket. In other words, the relative position of the first fixing part 100 and the second fixing part 200 can be adjusted by the step connection part 300, so that the special-shaped screen splicing bracket can be compatible with special-shaped splicing screens of various curvatures, thicknesses, and curvatures, so that the special-shaped unit display screens can be positioned, fixed and spliced ​​by the special-shaped screen splicing bracket.

[0074] Alternatively, if Figures 1 to 10As shown, the special-shaped spliced ​​screen includes a first unit display screen 1000 and a second unit display screen 2000, wherein the first unit display screen 1000 may be a convex curved unit display screen, and the second unit display screen 2000 may be a concave curved unit display screen. In order to make the display surface of the first unit display screen 1000 and the display surface of the second unit display screen 2000 transition continuously and smoothly, when splicing the spliced ​​outer frame of the first unit display screen 1000 and the spliced ​​outer frame of the second unit display screen 2000 in the first direction F1, it is necessary to adjust the positions of the fixed rear shell 2100 of the second unit display screen and the fixed rear shell 2100 of the second unit display screen in the second direction F2, so that the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen are staggered in the first direction F1 and have a certain distance in the second direction F2. In the embodiment of the present application, the first fixing part 100 and the second fixing part 200 have a splicing height difference D in the second direction F2 through the stepped connecting part 300, that is, the fixed positions of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen in the second direction F2 are adjusted, so that the splicing outer frame of the first unit display screen 1000 and the splicing outer frame of the second unit display screen 2000 can be spliced ​​together, and the display surface of the first unit display screen 1000 and the display surface of the second unit display screen 2000 are continuous and smoothly transitioned, ensuring that after the first unit display screen 1000 and the second unit display screen 2000 are positioned and fixed by the special-shaped screen splicing bracket, the splicing gap between the first unit display screen 1000 and the second unit display screen 2000 is small, the display surface is continuous and smoothly transitioned, and the splicing display effect of the special-shaped splicing screen is improved.

[0075] Alternatively, if Fig.18 As shown, the special-shaped splicing screen includes a first unit display screen 1000 and a second unit display screen 2000, wherein the first unit display screen 1000 may be a convex curved unit display screen, and the second unit display screen 2000 may be a flat unit display screen. In order to make the display surface of the first unit display screen 1000 and the display surface of the second unit display screen 2000 continuous and smoothly transition, the relative position of the first fixing part 100 and the second fixing part 200 in the second direction F2 can be adjusted by the step connection part 300, so that the first fixing part 100 and the second fixing part 200 have a splicing height difference D in the second direction F2 to adapt to the relative position of the fixed rear shell 1100 of the first unit display screen relative to the fixed rear shell 2100 of the second unit display screen. After the first unit display screen 1000 and the second unit display screen 2000 are constrained and fixed by the special-shaped screen splicing bracket, the splicing gap between the first unit display screen 1000 and the second unit display screen 2000 can be made smaller, and the display surface can be continuous and smoothly transitioned.

[0076] As an optional implementation, Figures 14 to 20 As shown, there is a splicing angle θ between the first fixing portion 100 and the second fixing portion 200 .

[0077] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 14 to 20 As shown, there is a splicing angle θ between the first fixing part 100 and the second fixing part 200, so that the second fixing part 200 changes its angle obliquely relative to the first fixing part 100, and the structural changes between the first unit display screen 1000 and the second unit display screen 2000 are adapted through the splicing angle θ, so that the first unit display screen 1000 and the second unit display screen 2000 are constrained and fixed through the special-shaped screen splicing bracket. In other words, the relative position of the first fixing part 100 and the second fixing part 200 can be adjusted through the angle between the first fixing part 100 and the second fixing part 200, so that the special-shaped screen splicing bracket can be compatible with special-shaped splicing screens of different structures, so that the special-shaped unit display screens can be positioned, fixed and spliced ​​through the special-shaped screen splicing bracket.

[0078] Alternatively, if Figures 14 to 20 As shown, the special-shaped spliced ​​screen includes a first unit display screen 1000 and a second unit display screen 2000, wherein the first unit display screen 1000 may be a concave curved unit display screen, and the second unit display screen 2000 may be a flat unit display screen. In order to make the display surface of the first unit display screen 1000 and the display surface of the second unit display screen 2000 transition continuously and smoothly, when splicing the spliced ​​outer frame of the first unit display screen 1000 and the spliced ​​outer frame of the second unit display screen 2000 in the first direction F1, it is necessary to adjust the relative position and angle between the fixed rear shell 2100 of the second unit display screen and the fixed rear shell 2100 of the second unit display screen, so that the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen are staggered with each other in the first direction F1 and the second direction F2 and have a certain angle. In the embodiment of the present application, a splicing angle θ is provided between the first fixing portion 100 and the second fixing portion 200, and the relative position of the first fixing portion 100 and the second fixing portion 200 is adjusted by the splicing angle θ, that is, the relative position of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen is adjusted, so that the splicing outer frame of the first unit display screen 1000 and the splicing outer frame of the second unit display screen 2000 can be spliced ​​together, and the display surface of the first unit display screen 1000 and the display surface of the second unit display screen 2000 are continuous and smoothly transitioned, ensuring that after the first unit display screen 1000 and the second unit display screen 2000 are positioned and fixed by the special-shaped screen splicing bracket, the splicing gap between the first unit display screen 1000 and the second unit display screen 2000 is small, the display surface is continuous and smoothly transitioned, and the splicing display effect of the special-shaped splicing screen is improved.

[0079] Alternatively, if Fig.18 and Fig.19 As shown, the special-shaped spliced ​​screen includes a first unit display screen 1000 and a second unit display screen 2000, wherein the first unit display screen 1000 may be a convex curved unit display screen, and the second unit display screen 2000 may be a flat unit display screen. In order to make the display surface of the first unit display screen 1000 and the display surface of the second unit display screen 2000 transition continuously and smoothly, the relative position of the first fixing part 100 and the second fixing part 200 in the second direction F2 can be adjusted by the stepped connecting part 300. At the same time, by making a certain splicing angle θ between the first fixing part 100 and the second fixing part 200, the first fixing part 100 and the second fixing part 200 have a splicing height difference D in the second direction F2. At the same time, the relative angle between the first fixing part 100 and the second fixing part 200 is changed to adapt to the relative position of the fixed rear shell 1100 of the first unit display screen relative to the fixed rear shell 2100 of the second unit display screen. After the first unit display screen 1000 and the second unit display screen 2000 are constrained and fixed by the special-shaped screen splicing bracket, the splicing gap between the first unit display screen 1000 and the second unit display screen 2000 can be made smaller, and the display surfaces of the first unit display screen 1000 and the second unit display screen 2000 can achieve a continuous and smooth transition.

[0080] As an optional implementation, Figure 5 and Figure 6 As shown, the first unit display screen 1000 is a first curved display screen, the second unit display screen 2000 is a second curved display screen, and the splicing height difference D is the sum of the first curved surface height D_1 of the first curved display screen and the second curved surface height D_2 of the second curved display screen; wherein the first curved surface height D_1 is the maximum distance between different display areas of the first curved display screen; and the second curved surface height D_2 is the maximum distance between different display areas of the second curved display screen.

[0081] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figure 5 and Figure 6 As shown, when the first unit display screen 1000 is a first curved display screen and the second unit display screen 2000 is a second curved display screen, the splicing height difference D is set to adapt to the position change of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen caused by the curved structure of the first curved display screen and the second curved display screen. When the thickness of the first unit display screen 1000 and the thickness of the second unit display screen 2000 are the same, Figure 6It can be seen from the figure that, relative to the flat display screen, the position change of the fixed rear shell position of the first curved display screen and the fixed rear shell position of the second curved display screen in the second direction F2 is mainly positively correlated with the first curved surface height D_1 of the first curved display screen and the second curved surface height D_2 of the second curved display screen. The total position change of the fixed rear shell position of the first curved display screen and the fixed rear shell position of the second curved display screen in the second direction F2 is the sum of the first curved surface height D_1 and the second curved surface height D_2. In order to enable the special-shaped screen splicing bracket to position and fix the first curved display screen and the second curved display screen, it is necessary to make the splicing height difference D and the total position change of the fixed rear shell position of the first curved display screen and the fixed rear shell position of the second curved display screen in the second direction F2 equivalent, that is to say, the splicing height difference D can be made the sum of the first curved surface height D_1 and the second curved surface height D_2.

[0082] It should be noted that, in the embodiments of the present application, when calculating numerical parameters such as the splicing height difference D and the splicing angle, there may be certain preparation errors, measurement errors or assembly errors, etc., which are not mathematical calculations in the strict sense.

[0083] As an optional implementation, the splicing height difference D satisfies the following formula:

[0084]

[0085] Wherein, D is the splicing height difference D, R1 is the first curvature radius of the first curved display screen, L1 is the first curved length of the first curved display screen in the first direction, R2 is the second curvature radius of the second curved display screen, and L2 is the second curved length of the second curved display screen in the first direction.

[0086] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 10 As shown, when the first unit display screen 1000 is a first curved display screen and the second unit display screen 2000 is a second curved display screen, the first curved display screen and the second curved display screen are spliced ​​and assembled through a special-shaped splicing bracket to form an S-shaped special-shaped display screen. The size of the special-shaped screen splicing bracket is related to the size, curvature radius and other parameters of the first curved display screen and the second curved display screen.

[0087] Alternatively, if Figure 5 and Figure 6 As shown, the first curved display screen is a convex curved display screen, and the second curved display screen is a concave curved display screen, which can be positioned and spliced ​​by a special-shaped splicing bracket to form an S-shaped special-shaped splicing screen. According to the length and curvature radius parameters of the convex curved display screen and the concave curved display screen, the splicing height difference D satisfies the following formula:

[0088]

[0089] Wherein, D is the splicing height difference D, R1 is the first curvature radius of the first curved display screen, L1 is the first curved length of the first curved display screen in the first direction, R2 is the second curvature radius of the second curved display screen, and L2 is the second curved length of the second curved display screen in the first direction.

[0090] For example, in the special-shaped splicing screen, the first curved display screen and the second curved display screen are both 43-inch curved display screens, then the first curved length L1 of the first curved display screen in the first direction and the second curved length L2 of the second curved display screen in the first direction are both 965mm, the first curvature radius R1 of the first curved display screen and the second curvature radius R2 of the second curved display screen are both 1500mm. According to the calculation formula of the splicing height difference D, it can be known that the splicing height difference D of the special-shaped screen splicing bracket corresponding to the special-shaped splicing screen is 154mm.

[0091] As an optional implementation, Figure 5 and Figure 6 As shown, the first unit display screen 1000 is a first curved display screen, the second unit display screen 2000 is a second curved display screen, and the splicing height difference D is the sum of the first curved surface height D_1 of the first curved display screen, the second curved surface height D_2 of the second curved display screen, and the thickness difference between the first curved display screen and the second curved display screen; wherein, the first curved surface height D_1 is the maximum distance between different display areas of the first curved display screen; and the second curved surface height D_2 is the maximum distance between different display areas of the second curved display screen.

[0092] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figure 5 and Figure 6 As shown, when the first unit display screen 1000 is a first curved display screen and the second unit display screen 2000 is a second curved display screen, the splicing height difference D is set to adapt to the position change of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen caused by the curved structure of the first curved display screen and the second curved display screen. When the thickness of the first unit display screen 1000 and the thickness of the second unit display screen 2000 are different, it is also necessary to consider the influence of the thickness of the first unit display screen 1000 and the thickness of the second unit display screen 2000 on the position change of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen. Figure 6It can be seen that, relative to the flat display screen, the position change of the fixed rear shell position of the first curved display screen and the fixed rear shell position of the second curved display screen in the second direction F2 is mainly positively correlated with the first curved surface height D_1 of the first curved display screen, the second curved surface height D_2 of the second curved display screen, and the thickness difference between the first curved display screen and the second curved display screen. The total position change of the fixed rear shell position of the first curved display screen and the fixed rear shell position of the second curved display screen in the second direction F2 is the sum of the first curved surface height D_1, the second curved surface height D_2, and the thickness difference between the first curved display screen and the second curved display screen. In order to enable the special-shaped screen splicing bracket to position and fix the first curved display screen and the second curved display screen, it is necessary to make the splicing height difference D equal to the total position change of the fixed rear shell position of the first curved display screen and the fixed rear shell position of the second curved display screen in the second direction F2, that is, the splicing height difference D can be made the sum of the first curved surface height D_1, the second curved surface height D_2, and the thickness difference between the first curved display screen and the second curved display screen.

[0093] As an optional implementation, the splicing height difference D satisfies the following formula:

[0094]

[0095] Wherein, D is the splicing height difference D, R1 is the first curvature radius of the first curved display screen, L1 is the first curved length of the first curved display screen in the first direction, d1 is the first thickness of the first curved display screen, R2 is the second curvature radius of the second curved display screen, L1 is the second curved length of the second curved display screen in the first direction, and d2 is the second thickness of the second curved display screen.

[0096] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 10 As shown, when the first unit display screen 1000 is a first curved display screen and the second unit display screen 2000 is a second curved display screen, the first curved display screen and the second curved display screen are spliced ​​and assembled through a special-shaped splicing bracket to form an S-shaped special-shaped display screen. The size of the special-shaped screen splicing bracket is related to the size, thickness, curvature radius and other parameters of the first curved display screen and the second curved display screen.

[0097] Alternatively, if Figure 5 and Figure 6 As shown, the first curved display screen is a convex curved display screen, and the second curved display screen is a concave curved display screen, which can be positioned and spliced ​​by a special-shaped splicing bracket to form an S-shaped special-shaped splicing screen. According to the length, curvature radius and thickness parameters of the convex curved display screen and the concave curved display screen, the splicing height difference D satisfies the following formula:

[0098]

[0099] like Figure 5 and Figure 6 As shown, the first thickness d1 of the first curved display screen and the second thickness d2 of the second curved display screen may include structural thicknesses such as the thickness of a display module of the curved display screen and the thickness of a system board.

[0100] As an optional implementation, Figures 1 to 10 As shown, the length S of the special-shaped screen splicing bracket in the first direction is 40% to 100% of the sum of the first length of the first unit display screen 1000 in the first direction F1 and the second length of the second unit display screen 2000 in the first direction F1.

[0101] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 10 As shown, the length S of the special-shaped screen splicing bracket in the first direction is related to the structure of each unit display screen in the special-shaped splicing screen. Since the first fixing part 100 of the special-shaped screen splicing bracket fixes the first unit display screen 1000 by connecting with the fixed rear shell 1100 of the first unit display screen, and the second fixing part 200 fixes the second unit display screen 2000 by connecting with the fixed rear shell 2100 of the second unit display screen, the special-shaped screen splicing bracket needs to be able to correspond to the positions of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen. The length S of the bracket in the first direction needs to correspond to the sum of the lengths of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen in the first direction F1, and since the special-shaped splicing bracket does not necessarily need to be fixed to the edges of the fixed rear shell 1100 of the first unit display screen and the fixed rear shell 2100 of the second unit display screen, the length S of the special-shaped screen splicing bracket in the first direction can be 40% to 100% of the sum of the first length of the first unit display screen 1000 in the first direction F1 and the second length of the second unit display screen 2000 in the first direction F1. Optionally, the length S of the special-shaped screen splicing bracket in the first direction can be adaptively adjusted according to the structural size of each unit display screen in the special-shaped splicing screen and the specific connection position. For example, the length S of the special-shaped screen splicing bracket in the first direction is 40%, 45%, 50%, 60%, 70%, 80%, 90%, 100%, etc. of the sum of the first length of the first unit display screen 1000 in the first direction F1 and the second length of the second unit display screen 2000 in the first direction F1.

[0102] As an optional implementation, Figures 1 to 10As shown, the first unit display screen 1000 is a first curved display screen, the second unit display screen 2000 is a second curved display screen, and the length S of the special-shaped screen splicing bracket in the first direction satisfies the following formula:

[0103]

[0104] Among them, S is the length of the special-shaped screen splicing bracket in the first direction, R1 is the first curvature radius of the first curved display screen, L1 is the first curved length of the first curved display screen in the first direction, R2 is the second curvature radius of the second curved display screen, and L1 is the second curved length of the second curved display screen in the first direction.

[0105] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 10 As shown, when the first unit display screen 1000 is a first curved display screen and the second unit display screen 2000 is a second curved display screen, the first length of the first unit display screen 1000 in the first direction F1 can be expressed as The second length of the second unit display screen 2000 in the first direction F1 can be expressed as: Then the length S of the special-shaped screen splicing bracket in the first direction can be

[0106]

[0107] As an optional implementation, Figures 1 to 10As shown, the width W of the special-shaped screen splicing bracket in the third direction is related to the fixed position selected for the fixed rear shell of the unit display screen, that is, the width W of the special-shaped screen splicing bracket in the third direction is related to the spacing of the first fixing holes 110 on the first fixing part 100 in the third direction F3 and the spacing of the second fixing holes 210 on the second fixing part 200 in the third direction F3. VESA (Video Electronics Standards Association) has standardized the interface standard of the mounting bracket for flat-panel displays such as screens and televisions, namely the VESA Mount Interface Standard (VESA Mount). In combination with the VESA installation interface standard, the spacing of the first fixing holes 110 in the third direction F3 and the spacing of the second fixing holes 210 in the third direction F3 can be 100mm / 200mm / 400mm, and the width W of the special-shaped screen splicing bracket in the third direction needs to be at least 50mm larger than the spacing of the first fixing holes 110 in the third direction F3 and the spacing of the second fixing holes 210 in the third direction F3. Therefore, the width W of the special-shaped screen splicing bracket in the third direction can be 150mm~450mm, and the width W of the special-shaped screen splicing bracket in the third direction can also be greater than or equal to 450mm. For example, when the spacing of the first fixing holes 110 in the third direction F3 and the spacing of the second fixing holes 210 in the third direction F3 are respectively 100 mm, the width W of the special-shaped screen splicing bracket in the third direction can be 150 mm to 450 mm; when the spacing of the first fixing holes 110 in the third direction F3 and the spacing of the second fixing holes 210 in the third direction F3 are respectively 200 mm, the width W of the special-shaped screen splicing bracket in the third direction can be 250 mm to 450 mm; when the spacing of the first fixing holes 110 in the third direction F3 and the spacing of the second fixing holes 210 in the third direction F3 are respectively 400 mm, the width W of the special-shaped screen splicing bracket in the third direction can be 450 mm or greater than 450 mm. Optionally, under the premise of ensuring that the width W of the special-shaped screen splicing bracket in the third direction is 50 mm greater than the spacing between the first fixing holes 110 in the third direction F3 and the spacing between the second fixing holes 210 in the third direction F3, and ensuring that the special-shaped screen splicing bracket has sufficient structural strength, the width W of the special-shaped screen splicing bracket in the third direction can be made as close as possible to the spacing between the first fixing holes 110 in the third direction F3 and the spacing between the second fixing holes 210 in the third direction F3, so as to reduce the space occupied by the special-shaped screen splicing bracket in the third direction F3 and save the material usage of the special-shaped screen splicing bracket.

[0108] As an optional implementation, Figures 14 to 20As shown, the first unit display screen 1000 is a curved display screen, the second unit display screen 2000 is a flat screen, and the splicing angle θ is the difference between 180° and half of the curved angle of the curved display screen.

[0109] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 14 to 20 As shown, when the first unit display screen 1000 is a curved display screen and the second unit display screen 2000 is a flat screen, the splicing angle θ can be set between the first fixing portion 100 and the second fixing portion 200 of the special-shaped screen splicing bracket to adjust the relative angle between the fixed rear shell of the curved display screen and the fixed rear shell of the flat display screen, so as to adapt to the change in the angle of the fixed rear shell of the curved display screen relative to the fixed rear shell of the flat display screen caused by the bending of the curved display screen. Fig.17 As shown, the splicing angle θ is related to the curvature angle of the curved display screen. Fig.17 It can be deduced that the splicing angle θ can be the difference between 180° and half of the curvature angle of the curved display screen.

[0110] As an optional implementation, Figures 14 to 20 As shown, the splicing angle θ satisfies the following formula:

[0111]

[0112] Wherein, θ is the splicing angle, R1 is the first curvature radius of the curved display screen, and L1 is the first curved length of the curved display screen in the first direction.

[0113] In some embodiments of the present application, in the special-shaped screen splicing bracket, when the first unit display screen 1000 is a curved display screen and the second unit display screen 2000 is a flat screen, Figures 14 to 20 As shown, the splicing angle θ can be expressed by the formula Obtained by calculation.

[0114] In the special-shaped screen splicing bracket of some embodiments of the present application, the special-shaped screen splicing bracket can be a plate-like structure.

[0115] As an optional implementation, Figure 4 As shown, the special-shaped screen splicing bracket is bent in a "J" shape in the third direction F3, and the third direction F3 is perpendicular to the first direction F1 and the second direction F2.

[0116] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figure 4As shown, in the third direction F3 perpendicular to the first direction F1 and the second direction F2, the special-shaped screen splicing bracket can be bent into a "J" shape. By bending the special-shaped screen splicing bracket into a "J" shape, the special-shaped screen splicing bracket can have greater strength when the size of the third direction F3 is small, which can improve the rigidity of the special-shaped screen splicing bracket and improve the supporting and fixing ability of each unit display screen of the special-shaped splicing screen.

[0117] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figure 4 As shown, the special-shaped screen splicing bracket is an integrated structure, which is used for splicing and fixing more than two unit display screens. It is the key load-bearing structure of the final splicing display device. Therefore, the special-shaped screen splicing bracket can be reinforced by adopting a "J"-shaped bending forming in the third direction F3. The special-shaped screen splicing bracket can form a raised structure as a reinforcing rib 400 in the middle part of the third direction F3, thereby improving the overall structural strength of the special-shaped screen splicing bracket.

[0118] As an optional implementation, Figure 4 As shown, the edge of the special-shaped screen splicing bracket in the third direction F3 is provided with a flange 500.

[0119] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figure 4 As shown, the edge of the special-shaped screen splicing bracket in the third direction F3 can be provided with a flange 500 to cooperate with the protruding structure to help enhance the structural strength of the special-shaped screen splicing bracket.

[0120] As an optional implementation, Figures 1 to 20 As shown, the special-shaped screen splicing bracket also includes a third fixing portion 600 , and the third fixing portion 600 is connected between the first fixing portion 100 or the second fixing portion 200 and the stepped connecting portion 300 .

[0121] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 20 As shown, a third fixing part 600 is provided between the first fixing part 100 and the step connection part 300, or a third fixing part 600 is provided between the first fixing part 100 and the step connection part 300, and the special-shaped screen splicing bracket can be fixed on a supporting structure such as a wall, a trolley bracket, or a base assembly 3000 through the third fixing part 600. In other words, after the special-shaped splicing screen is spliced ​​and assembled through the special-shaped screen splicing bracket, it can also be fixed as a whole on a supporting structure such as a wall or a trolley bracket through the special-shaped screen splicing bracket, which can be compatible with different supporting structures and realize multiple uses of one object.

[0122] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 20As shown, a fixing stud 610 may be provided on the third fixing portion 600 , so as to realize connection between the third fixing portion 600 and supporting structures such as a wall, a cart bracket, and a base assembly 3000 through the fixing stud 610 .

[0123] Alternatively, if Figures 1 to 20 As shown, four fixing studs 610 may be provided on the third fixing portion 600 , and the four fixing studs 610 are arranged in a rectangular shape on the third fixing portion 600 .

[0124] Alternatively, if Figures 1 to 20 As shown, in order to make the third fixing part 600 match various models of wall-mounted or cart brackets sold on the market, the spacing of the fixing studs 610 in the first direction F1 and the spacing in the third direction F3 meet the VESA installation interface standard. Optionally, the spacing of the fixing studs 610 in the first direction F1 is 400mm / 600mm, which can make the fixing studs 610 have a larger span in the first direction F1, which is conducive to the uniform distribution of the gravity of the special-shaped screen splicing bracket and improve the stability of the special-shaped screen splicing bracket. Optionally, the spacing of the fixing studs 610 in the third direction F3 is 200mm / 400mm.

[0125] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 1 to 20 As shown, the height of the fixing stud 610 can be greater than or equal to 20 mm to ensure that when the fixing screw 800 is screwed into the fixing stud 610 for fixing, the effective screw-in depth of the fixing screw 800 can be greater than or equal to 16 mm, thereby ensuring the reliability of fixing through the third fixing part 600.

[0126] In the special-shaped screen splicing bracket of some embodiments of the present application, the inner diameter of the fixing stud 610 is tapped M6 so that it can match various models of wall-mounted or carts sold on the market. The outer diameter (diameter) of the fixing stud 610 is greater than or equal to 20 mm to ensure the reliability of the connection of the fixing stud 610.

[0127] As an optional implementation, Figures 7 to 13 As shown, the special-shaped screen splicing bracket also includes an auxiliary bracket 700, which includes a first fixed end 710, a second fixed end 720, and an auxiliary connecting part 730 connected between the first fixed part 100 and the second fixed end 720. The first fixed end 710 is used to connect to the first unit display screen 1000, and the second fixed end 720 is used to connect to the second unit display screen 2000.

[0128] In some embodiments of the present application, in the special-shaped screen splicing bracket, such as Figures 7 to 13As shown, the special-shaped screen splicing bracket fixes the first unit display screen 1000 and the second unit display screen 2000 respectively through the first fixing part 100 and the second fixing part 200. After the first unit display screen 1000 and the second unit display screen 2000 are assembled through the special-shaped screen splicing bracket, they can initially form a whole.

[0129] Taking into account that the first unit display screen 1000 and the second unit display screen 2000 generate two forces on the special-shaped screen splicing bracket under the action of gravity, the first unit display screen 1000 and the second unit display screen 2000 may cause the special-shaped screen splicing bracket to deform outward when subjected to the two forces for a long time, thereby causing the splicing gap between the first unit display screen 1000 and the second unit display screen 2000 to increase.

[0130] In order to prevent the special-shaped screen splicing bracket from being deformed outward due to the gravity of the first unit display screen 1000 and the second unit display screen 2000, the special-shaped screen splicing bracket can also include an auxiliary bracket 700, such as Figures 7 to 13 As shown, the first fixed end 710 of the auxiliary bracket 700 is connected to the first unit display screen 1000, and the second fixed end 720 of the auxiliary bracket 700 is connected to the second unit display screen 2000. The first unit display screen 1000 and the second unit display screen 2000 are tightened together by the auxiliary bracket 700, thereby avoiding the increase of the splicing gap between the first unit display screen 1000 and the second unit display screen 2000 to a certain extent.

[0131] In some embodiments of the present application, Figures 7 to 13 As shown, the auxiliary bracket 700 can ensure that two adjacent unit display screens are effectively limited in six degrees of freedom, thereby ensuring that the seams between adjacent unit display screens are small and the edges of the unit display screens are neatly spliced.

[0132] As an optional implementation, Figures 7 to 13 As shown, the first fixing end 710 and the second fixing end 720 are respectively provided with auxiliary fixing holes, and the auxiliary fixing holes are runway holes 740 extending along the first direction F1.

[0133] In some embodiments of the present application, Figures 7 to 13 As shown, by making the auxiliary fixing hole a runway hole 740 extending along the first direction F1, an eccentric hollow design is formed between the auxiliary bracket 700 and the first unit display screen 1000 and the second unit display screen 2000. After the fixing screw 800 is fastened through the auxiliary fixing hole, the two adjacent unit screens can be tightly matched through the pulling force of the fixing screw 800, and it has a corrective effect in the up and down direction and the front and back direction.

[0134] In some embodiments of the present application, Figures 7 to 13 As shown, by setting the auxiliary fixing hole of the auxiliary bracket 700 as a runway hole 740 extending along the first direction F1, the problem of failure to assemble the auxiliary bracket 700 due to uneven force and assembly tolerance during actual assembly can be solved.

[0135] Optionally, the radius of the runway hole 740 adopts a commonly used M4 threaded hole.

[0136] As an optional implementation, Figures 7 to 13 As shown, the auxiliary bracket length s between the first fixed end 710 and the second fixed end 720 and the auxiliary bracket height h of the auxiliary connecting portion 730 relative to the first fixed end 710 and the second fixed end 720 conform to the holding size of the human hand.

[0137] In some embodiments of the present application, Figures 7 to 13 As shown, the auxiliary bracket 700 can be formed into an "arch bridge" structure as a whole through the auxiliary connecting portion 730, so that the auxiliary bracket 700 is easy to hold.

[0138] Optionally, in order to facilitate the auxiliary bracket 700 to be held and assembled, Figures 7 to 13 As shown, the auxiliary bracket length s between the first fixed end 710 and the second fixed end 720 can be set to 130 mm ± 50 mm, and the auxiliary bracket height h of the auxiliary connecting part 730 relative to the first fixed end 710 and the second fixed end 720 can be set to 28 mm ± 8 mm, which makes it convenient for operators to hold the auxiliary bracket 700 during the assembly process and improves assembly efficiency.

[0139] Alternatively, if Figures 7 to 13 As shown, the number of auxiliary brackets 700 can be set according to the weight and the length of the joint of the first unit display screen 1000 and the second unit display screen 2000. When the weight of the first unit display screen 1000 and the second unit display screen 2000 is large or the length of the joint is long, the number of auxiliary brackets 700 can be appropriately increased; when the weight of the first unit display screen 1000 and the second unit display screen 2000 is small and the length of the joint is short, the number of auxiliary brackets 700 can be appropriately reduced. For example, when the first unit display screen 1000 and the second unit display screen 2000 are 43-inch unit display screens respectively, two auxiliary brackets 700 can be set on the joint gap between the first unit display screen 1000 and the second unit display screen 2000.

[0140] In some embodiments of the present application, optionally, in order to ensure the fixing effect of the auxiliary bracket 700, the auxiliary bracket 700 is fixed to the back panels of the first unit display screen 1000 and the second unit display screen 2000 to avoid deformation defects of the unit display screens due to insufficient strength when the auxiliary bracket 700 is fixed to the fixed back shell.

[0141] Based on the same inventive concept, the present application embodiment proposes a splicing display device, such as Fig.21 and Fig. 22 As shown, the spliced ​​display device includes a special-shaped spliced ​​screen and the above-mentioned special-shaped screen splicing bracket.

[0142] Since the splicing display device provided by the utility model includes the special-shaped screen splicing bracket of the above technical solution, all the beneficial effects of the special-shaped screen splicing bracket of the splicing display device provided by the utility model will not be described in detail here.

[0143] As an optional implementation, Fig.21 and Fig. 22 As shown, the spliced ​​display device includes a first unit display screen 1000 and a second unit display screen 2000 spliced ​​in a first direction F1 , and non-spliced ​​outer frames 1200 of the first unit display screen 1000 and the second unit display screen 2000 are provided with chamfers 1210 .

[0144] In some embodiments of the present application, Fig.21 and Fig. 22 As shown, by providing the non-spliced ​​outer frame 1200 of the first unit display screen 1000 and the second unit display screen 2000 with a chamfer 1210, the visual effect of the non-spliced ​​outer frame 1200 is improved by the gradual structure of the chamfer 1210, so that the non-spliced ​​outer frame 1200 of the first unit display screen 1000 and the second unit display screen 2000 visually presents a narrower appearance effect, thereby ensuring the beautiful appearance of the non-spliced ​​outer frame 1200; at the same time, the spliced ​​outer frame of the first unit display screen 1000 and the second unit display screen 2000 is not affected by the chamfer 1210, thereby ensuring that the first unit display screen 1000 and the second unit display screen 2000 are neatly spliced.

[0145] In some embodiments of the present application, Fig.21 and Fig. 22 As shown, the outer frame thickness T1 of the first unit display screen 1000 and the second unit display screen 2000 can be 1.0mm-2.5mm. If the outer frame thickness T1 is too small, the strength is weak and the outer frame is easy to break; if the outer frame thickness T1 is too large, the outer frame will be unnecessarily thickened, affecting the overall appearance. In some embodiments of the present application, the chamfer height H can be 4mm-10mm. If the chamfer height H is too small, the visual effect of the gradual thinning of the outer frame thickness T1 cannot be achieved; if the chamfer height H is too large, the side appearance of the unit display screen will be affected.

[0146] In some embodiments of the present application, Fig.21 and Fig. 22As shown, the chamfer thickness T2 can be 0.3mm-0.5mm. If the chamfer thickness T2 is too small, it is difficult to manufacture and cannot be processed; if the chamfer thickness T2 is too large, the appearance optimization significance of the gradual thinning of the outer frame chamfer 1210 is lost.

[0147] In some embodiments of the present application, Fig.21 and Fig. 22 As shown, a rounded transition is provided at the connection position between the spliced ​​outer frame and the non-spliced ​​outer frame 1200, so that the thickness of the spliced ​​outer frame gradually changes to the chamfer thickness T2 of the non-spliced ​​outer frame 1200, thereby ensuring that the spliced ​​surface of the first unit display screen 1000 and the second unit display screen 2000 has no visual gap, thus forming a seamless appearance.

[0148] In some embodiments of the present application, the unit display screen may be a liquid crystal display screen, which includes a liquid crystal display module and its own backlight structure.

[0149] In some embodiments of the present application, the unit display screen may also be an OLED display screen.

[0150] In some embodiments of the present application, the fixed rear shell of the unit display screen, the spliced ​​outer frame and the non-spliced ​​outer frame 1200 together constitute the outer shell of the unit display screen, and the outer shell is made of materials including but not limited to plastic, metal and the like.
