Description

Technical Field

[0001] This application relates to the field of display device manufacturing, and more specifically, to a video wall and a method for assembling a video wall. Background Technology

[0002] In some display applications, multiple individual displays need to be spliced ​​together to form a larger display screen to achieve a wider display area. To improve the display effect of the spliced ​​screen, the spacing between the individual displays needs to be minimized to achieve seamless splicing. However, the individual displays used to achieve seamless splicing usually have side wiring. Friction or collisions during the splicing process can cause the side wiring to detach, resulting in the individual display malfunctioning. Furthermore, for individual displays with glass substrates that offer better display quality but are also more brittle, squeezing and collisions between the individual displays can easily damage or even shatter the glass substrate. Summary of the Invention

[0003] To overcome the technical problems mentioned in the above background, embodiments of this application provide a video wall, the video wall comprising:

[0004] At least two individual display screens, wherein the display surfaces of each individual display screen face the same side and are arranged on the same layer;

[0005] At least one airbag located between two adjacent single displays, the airbag being made of a flexible material.

[0006] In one possible implementation, the outer wall of the airbag that contacts the monolithic display screen is adhesive.

[0007] In one possible implementation, the inner wall corresponding to the outer wall of the airbag that contacts the monolithic display screen is adhesive.

[0008] In one possible implementation, a plurality of airbags are provided between two adjacent individual display screens, extending along the side of the two individual display screens where they are attached.

[0009] In one possible implementation, among the multiple airbags between two adjacent individual display screens, a gap may exist between two adjacent airbags; or

[0010] Among the multiple airbags between two adjacent individual display screens, adjacent airbags are in close contact with each other; or

[0011] The multiple airbags between two adjacent single display screens are formed by multiple grids set in a long strip-shaped integral airbag.

[0012] In one possible implementation, the width of the airbag perpendicular to the display surface is smaller than the thickness of the single display screen perpendicular to the display surface.

[0013] In one possible implementation, the airbag includes a first region that contacts the single display screen and a second region that does not contact the single display screen, the second region being provided with an exhaust port.

[0014] In one possible implementation, the airbag includes a first region that contacts the single display screen and a second region that does not contact the single display screen, wherein the thickness of the airbag in the second region is less than the thickness of the airbag in the first region.

[0015] In one possible implementation, the thickness of the airbag is less than or equal to 50 micrometers.

[0016] Another objective of this application is to provide a method for assembling a video wall, the method comprising:

[0017] At least one inflatable airbag is provided on at least one side of the first single display screen that has been attached to the carrier substrate.

[0018] A second single-unit display screen is disposed on the carrier substrate, and one side of the second single-unit display screen is used to compress the airbag to deflate the airbag until the side of the second single-unit display screen is spliced ​​and attached to the side of the first single-unit display screen.

[0019] Compared with the prior art, this application has the following beneficial effects:

[0020] This application provides an assembly method for splicing screens and splicing components.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0036] As mentioned in the background section, the inventors have discovered that traditional display splicing solutions often use PCB-based displays. Due to the inherent toughness of PCBs, PCB-based displays offer relatively good resistance to collisions and pressure during installation. In contrast, glass-based displays offer advantages such as high display accuracy, active drive capability, flicker-free operation, resistance to heat deformation, high flatness, and the ability to scale up the substrate. However, glass substrates are relatively harder and more brittle than PCB substrates, making them more susceptible to damage or even breakage during installation due to collisions or pressure. In some glass-based single-display splicing solutions, to avoid damage to the glass substrate, the gaps between individual displays must be intentionally increased, resulting in a decrease in the overall display effect of the spliced ​​screen.

[0037] In view of this, this embodiment provides a splicing screen and a splicing screen assembly method, which can effectively avoid the side traces of the individual display screen being scratched and prevent the substrate of the individual display screen from being damaged while maintaining a small splicing gap. The solution provided in this embodiment will be explained in detail below.

[0038] Please see Figure 1 , Figure 1 This is a schematic diagram of a splicing screen provided in this embodiment. The splicing screen may include at least two individual display screens 100 and an airbag 200 located between two adjacent individual display screens 100.

[0039] The display surfaces of the individual display screens 100 face the same side and are arranged on the same layer. At least one airbag 200 is disposed between two adjacent individual display screens 100. The airbag 200 is made of a flexible material. For example, the airbag 200 can be made of rubber or polyimide material.

[0040] When the two individual display screens 100 are not yet spliced ​​together, the inflated airbag 200 can be placed on the side of one of the individual display screens 100. When inflated, the airbag 200 can have a relatively wide overall thickness.

[0041] When two individual display screens 100 are assembled together, the airbag 200 can be compressed to deflate it. During deflation, the airbag 200 can cushion collisions or scratches between the two individual display screens 100. When the airbag 200 is deflated and flattened, it has a thinner overall shape, thereby minimizing the gap between the two individual display screens 100 and improving the overall display effect of the spliced ​​screen.

[0042] Based on the above design, in the splicing screen provided in the embodiments of this application, by setting an airbag 200 between two adjacent single display screens 100, the two adjacent single display screens 100 can be buffered by the airbag 200 during splicing assembly, so as to effectively avoid the side wiring of the single display screen 100 being scratched while maintaining a small splicing gap, and prevent the substrate of the single display screen 100 from being damaged, thereby improving the splicing success rate.

[0043] In one possible implementation, the airbag 200 at least covers the side wiring of the single display screen 100. Thus, the airbag 200 can protect the side wiring of the single display screen 100, preventing it from being scratched or damaged during the splicing process.

[0044] In one possible implementation, during the splicing and assembly process, the airbag 200 can be first glued to one side of one of the single display screens 100 using an adhesive, and then another display screen can be glued to the airbag 200 using an adhesive.

[0045] In another possible implementation, the outer wall of the airbag 200 that contacts the single display screen 100 is adhesive. Thus, during the assembly process, the outer wall of the airbag 200 can be directly bonded to the side wall of the single display screen 100.

[0046] Furthermore, in one possible implementation, the entire outer wall of the airbag 200 may be adhesive.

[0047] In another possible implementation, the inner wall of the airbag 200 that contacts the outer wall of the single display screen 100 is adhesive. Thus, after the airbag 200 is flattened and deflated, its inner walls can adhere to each other, thereby preventing relative movement of the inner walls of the airbag 200 and improving the adhesion stability of adjacent single display screens 100.

[0048] Furthermore, in one possible implementation, the entire inner wall of the airbag 200 may be adhesive.

[0049] Furthermore, in one possible implementation, the airbag 200 may be made entirely of a flexible material with a certain degree of viscosity.

[0050] Please refer to this again. Figure 1 In one possible implementation, the airbag 200 can be elongated. Since the airbag 200 will undergo a certain degree of stretching deformation after being flattened, in this embodiment, the length of the long side of the airbag 200 can be less than the length of the side of the single display screen 100. In this way, the sides of two adjacent single display screens 100 that need to be spliced ​​and fitted can be protected more completely.

[0051] Please refer to Figure 2 In another possible implementation, multiple airbags 200 are arranged between two adjacent individual display screens 100, extending along the side where the two individual display screens 100 are attached. Thus, by having multiple airbags 200 individually perform deflation and buffering actions, the adjacent individual display screens 100 can move closer together more smoothly during the splicing and bonding process.

[0052] In one example, please refer to Figure 3 Among the multiple airbags 200 between two adjacent single display screens 100, there may be a certain gap between two adjacent airbags 200.

[0053] In another example, please refer to Figure 4 Among the multiple airbags 200 between two adjacent single display screens 100, the two adjacent airbags 200 can be close to each other; or, the multiple airbags 200 between two adjacent single display screens 100 can be formed by setting multiple grids in a long strip of integral airbag.

[0054] Please refer to Figure 5In this embodiment, since the airbag 200 will undergo a certain degree of stretching deformation after being flattened, the width D1 of the airbag 200 in the direction perpendicular to the display surface is smaller than the thickness D2 of the single display screen 100 in the direction perpendicular to the display surface. This avoids the airbag 200 extending beyond the display surface and affecting the overall display effect of the splicing screen.

[0055] Furthermore, in this embodiment, the width of the airbag 200 perpendicular to the display surface when it is inflated can be smaller than the width of the airbag 200 perpendicular to the display surface when it is flattened.

[0056] In one possible implementation, please refer to Figure 6 The airbag 200 includes a first region 201 that contacts the single display screen 100 and a second region 202 that does not contact the single display screen 100. The second region 202 is provided with an exhaust port 210. Thus, during the splicing and assembly process, when the inflated airbag 200 is compressed by two single display screens 100, the gas inside the airbag 200 can be smoothly discharged through the exhaust port 210 from the second region 202 that does not contact the single display screen 100. Preferably, if there are multiple airbags between two adjacent single display screens 100, each airbag includes at least one exhaust port 210.

[0057] In another possible implementation, please refer to Figure 7 The airbag 200 includes a first region 201 that contacts the single display screen 100 and a second region 202 that does not contact the single display screen 100. Please refer to... Figure 8 , Figure 8 for Figure 7 As shown in the cross-sectional view along direction AA, the thickness D3 of the airbag 200 in the second region 202 is less than the thickness D4 of the airbag 200 in the first region 201. Thus, during the assembly process, when the inflated airbag 200 is compressed by the two individual display screens 100, due to the smaller thickness of the second region 202, the airbag 200 can rupture at the second region 202, allowing the gas inside the airbag 200 to be smoothly expelled from the second region 202, which is not in contact with the individual display screens 100.

[0058] In one possible implementation, the thickness of the airbag 200 is less than or equal to 50 micrometers. Preferably, the thickness of the first region 201 of the airbag 200 is less than 50 micrometers, for example, Figure 8The thickness shown in D4 is less than 50 micrometers. Thus, after the airbag 200 is flattened, the gap width between two adjacent individual display screens 100 can be less than 100 micrometers, thereby ensuring that the entire splicing screen has a good overall display effect.

[0059] In one possible implementation, the single display screen 100 may include a substrate, which may be a glass substrate.

[0060] Based on the same inventive concept, this embodiment also provides a splicing screen assembly method, please refer to... Figure 9 The method may include the following steps.

[0061] Step S110: At least one airbag 200 in an inflated state is provided on at least one side of the first single display screen that has been attached to the carrier substrate.

[0062] In this embodiment, a carrier substrate can be provided first, and the first single display screen can be attached to the carrier substrate by adhesive. Then, at least one airbag 200 can be provided on at least one side of the first single display screen.

[0063] Furthermore, the airbags 200 can be provided on the sides of the first single display screen that need to be attached to other single display screens.

[0064] Step S120: A second single-unit display screen is disposed on the carrier substrate, and one side of the second single-unit display screen is used to squeeze the airbag 200 to deflate the airbag 200 until the side of the second single-unit display screen is spliced ​​and attached to the side of the first single-unit display screen.

[0065] In this embodiment, the second single display screen is attached to the first single display screen under the cushioning of the airbag 200, and the second single display screen is also fixed to the carrier substrate by adhesive.

[0066] It is understood that in this embodiment, any single display screen that has been attached to the carrier substrate can be used as the first single display screen, and other single display screens that have not been spliced ​​and assembled can be used as the second single display screen and attached to the first single display screen.

[0067] In summary, the splicing screen and splicing assembly method provided in this application embodiment, by setting an airbag between two adjacent individual display screens, allows the two adjacent individual display screens to be spliced ​​together. During the splicing assembly, the airbag can buffer the impact or scratch that may occur during the splicing process. This effectively avoids the side wiring of the individual display screens being scratched while maintaining a small splicing gap, and prevents damage to the substrate of the individual display screens, thereby improving the splicing success rate.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
