[0037] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this disclosure, the solutions of the embodiments of this disclosure will be further described below. It should be noted that, unless otherwise specified, the embodiments of this disclosure and the features within them can be combined with each other.

[0038] Numerous specific details are set forth in the following description in order to provide a full understanding of the embodiments of this disclosure, but the embodiments of this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the embodiments of this disclosure, and not all embodiments.

[0039] One embodiment of this disclosure provides a display device, such as... Figure 1 and Figure 2 As shown, it includes a first display module, a second display module, a first connector 30, and a coating 40. Figure 1 This is a front view of the light-emitting surface of the display device. Figure 2 This is a cross-sectional view of the display device, where the X-direction is the light emission direction. Furthermore, to illustrate the connection relationship between the first display module, the second display module, and the first connector 30, Figure 1 (The coating 40 is not shown in the image), wherein:

[0040] The first display module includes a first cover plate 11 and a first light-emitting component 12, and the second display module includes a second cover plate 21 and a second light-emitting component 22. The first cover plate 11 and the second cover plate 21 are respectively adjacent to the opposite sides of the first connector 30.

[0041] It should be noted that "adjacent" only limits the positional relationship between the first cover plate 11, the second cover plate 21 and the first connector 30, and does not limit the first cover plate 11, the second cover plate 21 and the first connector 30 to have a connection relationship or direct contact relationship.

[0042] The coating 40 is located on the side of the first cover plate 11 and the second cover plate 21 away from the first light-emitting component 12 and the second light-emitting component 22, and covers at least a portion of the first cover plate 11, at least a portion of the second cover plate 21 and at least a portion of the first connector 30. The coating 40 includes a colored area, and the coating in the colored area includes a colored material. The coating in the colored area covers at least a portion of the adjacent area 31 of the first cover plate 11 and the first connector 30 and / or at least a portion of the adjacent area 32 of the second cover plate 21 and the first connector 30.

[0043] The display device provided in this disclosure, by splicing multiple cover plates, can meet diverse needs in terms of size and shape. For example, a large-size display device can be achieved by splicing multiple display modules through multiple connectors, ensuring structural strength while facilitating production and installation. Furthermore, by setting the bending angle between the display modules and the connectors, or by utilizing bent connectors, display devices of different shapes can be achieved, circumventing the technical shortcomings of bending cover plates in related technologies.

[0044] Furthermore, this disclosure also covers the splicing marks between the cover plate and the connector by using a film with colored material to cover the splicing marks, so that the spliced ​​display device can achieve visual integration, improve the visual effect of the display device, and also improve the user experience.

[0045] It should be noted that, Figure 1 as well as Figure 2 The embodiments described are merely exemplary, and the dimensional proportions of the first cover plate 11, the first light-emitting component 12, the second cover plate 21, the second light-emitting component 22, and the first connector 30 are not limited to these proportions. Figure 1 and Figure 2 In this embodiment, in order to increase the display area of ​​the display device, the width of the connector can be as small as possible compared to the cover plate, and the specific size can also be adjusted according to the specific usage scenario. The same applies to other figures in this embodiment, which will not be described again.

[0046] It should be noted that, Figure 2 The embodiments described are merely exemplary. In other embodiments, the first cover plate, the second cover plate, and the first connector may not be on the same plane, and the first cover plate, the second cover plate, and the first connector may not be parallel plate structures. Furthermore, this disclosure subsequently only shows embodiments of some display devices. The positions and shapes of other display modules differ from those in the embodiments of this disclosure, but display devices completed based on the inventive concept of the embodiments of this disclosure are all within the protection scope of this disclosure.

[0047] In one specific embodiment, the structure of the coating 40 in the colored area is as follows: Figure 3As shown, the structure includes an adhesive layer 41, a colored material layer 42, a substrate layer 43, and a surface coating layer 44, stacked sequentially away from the cover plate. Specifically, the adhesive layer 41 includes OCA (Optically Clear Adhesive) optical adhesive, and the material specifically includes adhesive materials such as acrylic, silicone, and / or polyurethane resins. The substrate layer 43 includes TAC (Triacetyl Cellulose), SRF (Super Retarder Film), PET (Polyethylene Glycol Terephthalate), and / or COP (Cyclo Olefin Polymer) film materials, wherein the haze of the film material of the substrate layer 43 is ≤2%, and the thickness is ≥50um. The surface coating layer 44 includes an AF (Anti-Fingerprint) coating, an AG (Anti-Glare) coating, an AR (Anti-Reflect) coating, and / or a hard coating (HC), wherein the thickness of the surface coating layer 44 is ≤1µm.

[0048] In one specific embodiment, the colored material layer 42 includes a colored material, resin, adhesive, curing agent, diluent, etc., wherein the colored material can be toner or silver powder. It should be noted that this disclosure only provides some embodiments of colored materials and does not limit the colored material to toner or silver powder. Other non-transparent colored materials that can achieve the same effect are all within the protection scope of this disclosure.

[0049] In another specific embodiment, the coating 40 in the colored area also includes an adhesive layer 41, a colored material layer 42, a substrate layer 43, and a surface coating layer 44. However, the colored material layer may be located between the substrate layer 43 and the surface coating layer 44. That is, the coating 40 in the colored area includes an adhesive layer 41, a substrate layer 43, a colored material layer 42, and a surface coating layer 44 stacked sequentially away from the cover plate.

[0050] In another specific embodiment, the coating 40 includes an adhesive layer 41, a substrate layer 43, and a surface coating layer 44 stacked sequentially away from the cover plate. The adhesive layer 41 in the colored area includes a colored material in addition to the materials described in the above embodiments.

[0051] In one specific embodiment, such as Figure 1 and Figure 2 As shown, the colored area is covered by a film covering all the adjacent parts 31 of the first cover plate 11 and the first connector 30, all the adjacent parts 32 of the second cover plate 21 and the first connector 30, and all the first connectors 30, so as to further realize the visual integration of the display device.

[0052] In some embodiments, such as Figure 2 and Figure 4 As shown, the first cover plate 11 includes a first light-emitting region 13 corresponding to the first light-emitting component 12, the second cover plate 21 includes a second light-emitting region 23 corresponding to the second light-emitting component 22, and the coating 40 also includes a colorless region. The coating 40 in the colorless region covers at least part of the first light-emitting region 13 and / or the second light-emitting region 23. The coating in the colorless region does not include colored materials.

[0053] The above embodiments, by covering the splicing marks with colored materials, maintain the colorless and light-transmitting part of the display module, which can ensure the brightness and clarity of the display module and further improve the user experience.

[0054] In one specific embodiment, the structure of the coating 40 is as follows: Figure 5 As shown, the colored region 401 includes a colored material layer 42, while the colorless region 402 does not include the colored material layer 42. For specific film structure and materials, please refer to [reference needed]. Figure 3 The specific implementation examples are not described here.

[0055] In some embodiments, such as Figure 4 and Figure 6 As shown, the first cover plate 11 includes a first light-emitting region 13 corresponding to the first light-emitting component 12, and the second cover plate 21 includes a second light-emitting region 23 corresponding to the second light-emitting component 22. The center point of the first light-emitting region 13 and the center point of the second light-emitting region 23 have a preset distance difference in the light-emitting direction X.

[0056] Traditional in-vehicle screens are typically divided into multiple areas, including an instrument panel for the driver and a central control screen. Different areas of the screen serve different functions; for example, the instrument panel displays driving-related data, while the central control screen displays entertainment-related content. The display device in the above embodiment utilizes the distance differences between multiple display modules in the light-emitting direction to meet the distance requirements of different displays relative to the vehicle interior. For example, if the central control screen needs to be easily operated by the front passenger and easily viewed by rear passengers, it can be positioned closer to the vehicle interior. Figure 6 In this embodiment, the second display module is set as the central control screen; however, to facilitate the driver's eye focus switching from a distant point to the screen while driving, the instrument panel needs to be placed away from the vehicle interior. Therefore, it can be... Figure 6 In this embodiment, the first display module is set as an instrument panel.

[0057] In one specific embodiment, both the first cover plate 11 and the second cover plate 21 are arc-shaped; in a more specific embodiment, such as... Figure 4 and Figure 7As shown, the first cover plate 11, the first light-emitting component 12, the second cover plate 21, and the second light-emitting component 22 are all arc-shaped. Figure 7 In the illustrated embodiment, the center point of the first light-emitting region 13 and the center point of the second light-emitting region 23 also have a preset distance difference in the light-emitting direction X, and can also meet the above-mentioned usage requirements. Furthermore, as... Figure 6 and Figure 7 As shown, the first display module can be closer to the light emission direction or farther away from the light emission direction relative to the second display module, both of which are within the protection scope of this disclosure. Specifically, the arc-shaped light emission component can be manufactured using flexible materials, which will not be elaborated further here. The curvature of the arc-shaped first cover plate 11 and the second cover plate 21 is within the range achievable by the cover plate material.

[0058] In some embodiments, such as Figure 8 and Figure 9 As shown, the display device also includes a third display module and a second connector 50. The third display module includes a third cover plate 61 and a third light-emitting component 62. The second cover plate 21 and the third cover plate 61 are respectively adjacent to the two sides opposite to the second connector 50.

[0059] The third cover plate 61 includes a third light-emitting region 63 corresponding to the third light-emitting component 62. The center point of the third light-emitting region 63 and the center point of the second light-emitting region 23 have a preset distance difference in the light-emitting direction X.

[0060] The colored area is covered by a film covering at least part of the junction 31 between the first cover plate 11 and the first connector 30, and / or at least part of the junction 32 between the second cover plate 21 and the first connector 30, and / or at least part of the junction 51 between the second cover plate 21 and the second connector 50, and / or at least part of the junction 52 between the third cover plate 61 and the second connector 50.

[0061] Traditional in-car screens also include a passenger-side screen, which, like the center console screen, displays entertainment-related content. To ensure ample space in the passenger seat and improve passenger comfort, the passenger-side screen also needs to be located away from other interior elements. This can be achieved by... Figure 8 and Figure 9 In this embodiment, the third display module is set as the passenger-side screen.

[0062] Those skilled in the art can combine Figure 7 , Figure 8 and Figure 9 The embodiment shown features a design where all three display modules have curved cover plates, which will not be elaborated upon here.

[0063] In some embodiments, such as Figure 4 and Figure 10As shown, the first cover plate 11 includes a first light-emitting region 13 corresponding to the first light-emitting component 12, and the second cover plate 21 includes a second light-emitting region 23 corresponding to the second light-emitting component 22. The plane or tangent plane at the center point of the first light-emitting region 13 intersects with the plane or tangent plane at the center point of the second light-emitting region 23.

[0064] The planes or tangential planes at the center points of the first cover plate 11 and the second cover plate 21 do not need to be parallel; they can have angular differences in different directions. This design allows for more flexible configuration of each display module. For example, by adjusting the tilt angle of the instrument panel on the driver's side, the angle between the instrument panel cover surface and the driver's line of sight can be made nearly perpendicular, and the angle of incidence can be made close to the angle of reflection, thus minimizing glare from other external light sources and further enhancing the driving experience.

[0065] Furthermore, in Figure 10 In the embodiment shown, the intersection of the plane or tangent plane at the center point of the first cover plate 11 and the second cover plate 21 is located on the side of the plane closer to the light-emitting component, and its display screen forms a surround view relative to the user, making it convenient for the user to view the content displayed by the two display modules.

[0066] In one specific embodiment, both the first cover plate 11 and the second cover plate 21 are arc-shaped; in a more specific embodiment, such as... Figure 4 and Figure 11 As shown, the first cover plate 11, the first light-emitting component 12, the second cover plate 21, and the second light-emitting component 22 are all arc-shaped. Figure 11 In the embodiment shown, the tangent plane at the center point of the first light-emitting region 13 intersects the center point of the second light-emitting region 23, and can also meet the above-mentioned usage requirements.

[0067] It should be noted that, although in Figure 10 and Figure 11 In the embodiments, the intersection of the plane or tangent plane at the center point of the first cover plate 11 and the second cover plate 21 is located on the side of the plane closer to the light-emitting component, but the intersection of the plane or tangent plane at the center point is located on the side of the plane farther away from the light-emitting component is also within the protection scope of this disclosure.

[0068] The above disclosure illustrates several embodiments of display devices consisting of two and three display modules. Those skilled in the art can, based on the above embodiments, splice more display modules into a complete display device without creative effort, all of which are within the protection scope of this disclosure.

[0069] In some embodiments, the junctions of the first cover plate and the second cover plate with the first connector form a smoothly transitioned curved surface on the light-emitting surface of the display device, facilitating film adhesion and improving the flatness of the display device surface. In a specific embodiment, the junctions of the second cover plate and the third cover plate with the second connector also form a smoothly transitioned curved surface on the light-emitting surface of the display device.

[0070] In some embodiments, the first cover plate and the second cover plate are connected to the first connector by an adhesive material.

[0071] Specifically, adhesive material can be added to fill the gaps at the junctions of the first cover plate and the first connector, and at the junctions of the second cover plate and the first connector, so that the junctions of the first cover plate and the second cover plate with the first connector form a smooth transition curved surface on the light-emitting surface of the display device. This adhesive material can be a low-shrinkage material. The same applies to the third cover plate and the second connector, and will not be described further.

[0072] In some embodiments, for example Figure 12 as well as Figure 13 The two embodiments shown ( Figure 12 as well as Figure 13 (All are cross-sectional views of the display device). The first cover plate 11 and the second cover plate 21 both include a fitting portion. The first connector 30 includes a first fitting portion 301 and a second fitting portion 302. The fitting portion 111 of the first cover plate 11 is fitted and connected to the first fitting portion 301 of the first connector 30. The fitting portion 211 of the second cover plate 21 is fitted and connected to the second fitting portion 302 of the first connector 30.

[0073] By using different shapes to splice the cover plate and connectors to complement each other, the gap difference can be reduced, and the flatness of the light-emitting surface of the display device can be further improved.

[0074] Figure 12 as well as Figure 13 The embodiments described above are merely exemplary. Other shapes of fitting parts, as long as they cause a portion of the main body of the first cover plate or the second cover plate to overlap with a portion of the main body of the first connector in the light emission direction, are all within the protection scope of this disclosure. The third cover plate and the second connector in the above embodiments are similar and will not be described again.

[0075] In some embodiments, the first cover plate and the second cover plate are connected to the first connector by ultrasonic welding or laser welding.

[0076] Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces rub against each other, causing fusion between molecular layers. Laser welding, on the other hand, uses a focused laser beam to bombard the workpieces, generating heat for welding. Since cover plates and connectors are mostly not made of metal, but rather plastic and glass, ultrasonic welding or laser welding can better fuse the materials at the junction of the cover plate and connector, achieving a secure connection. The third cover plate works similarly to the second connector, and will not be elaborated further.

[0077] In some embodiments, the first cover plate and the second cover plate are made of glass, and the first connector is made of plastic or metal.

[0078] Specifically, the cover of the display module is usually made of a composite material with glass as the main component, while the connectors, since they do not need to bear the display function, can be made of plastic or metal, further reducing production costs.

[0079] In some embodiments, the first display module and / or the second display module includes a capacitive touch screen, and the first cover plate and / or the second cover plate are glass covers of the capacitive touch screen that are furthest from the first light-emitting component and / or the second light-emitting component.

[0080] Specifically, when the display module is a capacitive touch screen, in order to ensure the sensitivity and accuracy of user touch, the outermost glass cover of the capacitive touch screen can be used as the cover adjacent to the connector.

[0081] In one specific embodiment, the display module without touch function may have more than one glass material layer in cross-sectional structure. In the embodiments of this disclosure, the first cover plate, the second cover plate and the third cover plate are all the outermost glass material layers in the display module that are far away from the first light-emitting component, the second light-emitting component and the third light-emitting component.

[0082] Based on the same inventive concept, corresponding to the display device of any of the above embodiments, this application also provides a transportation device, which includes any of the display devices in the above embodiments.

[0083] The aforementioned transportation equipment can be automobiles, ships, aircraft, etc., and the display device in the embodiments of this disclosure can be used to produce corresponding technical effects.

[0084] The transportation equipment described above includes the corresponding display device implemented in any of the foregoing embodiments and has the beneficial effects of the corresponding embodiments, which will not be repeated here.

[0085] Based on the same inventive concept, corresponding to the display device of any of the above embodiments, this application also provides an assembly method for a display device, such as... Figure 14 As shown, it includes:

[0086] S101, Provide encapsulation components.

[0087] Specifically, the aforementioned encapsulation component is a plastic back cover housing, which is an integrated design. Since the encapsulation component is not visible after the display device is installed on the transportation equipment, other technical means that cannot achieve the aesthetic requirements in the prior art can be used to complete the integrated manufacturing of the encapsulation component.

[0088] S102. Install the first display module, the second display module, and the first connector onto the encapsulation assembly.

[0089] The first display module includes a first cover plate and a first light-emitting component, and the second display module includes a second cover plate and a second light-emitting component. The first light-emitting component is located between the first cover plate and the encapsulation component, and the second light-emitting component is located between the second cover plate and the encapsulation component. The first cover plate and the second cover plate are respectively adjacent to the opposite sides of the first connector.

[0090] Specifically, the encapsulation component includes slots corresponding to the first display module, the second display module, and the first connector, which can be fixed to the encapsulation component via the slots.
