Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, specifically to an integrated backlight housing, a backlight assembly, a dual-screen display, and a vehicle. Background Technology

[0002] In recent years, with the rapid development of automotive intelligence and electrification, in-vehicle displays have become a core component for major OEMs to differentiate their products and enhance their technological and premium feel. In-vehicle displays not only serve functions such as information display and entertainment interaction, but have also gradually become an important element of automotive interior design. As consumers' demands for automotive technology and user experience continue to rise, the design and technology of in-vehicle displays are constantly evolving, with multi-screen and large-screen displays gradually becoming the mainstream trend in the industry.

[0003] Currently, the mainstream in-vehicle display solutions on the market are mainly divided into two types: one is an integrated large screen solution, and the other is a traditional splicing dual-screen or multi-screen solution. However, both of these solutions have certain technical limitations and drawbacks in practical applications, as detailed below:

[0004] 1) While integrated large screens offer a better overall visual appeal and a more technological feel, their manufacturing cost is significantly higher than traditional dual-screen splicing solutions. Market research data shows that integrated large screens typically cost 1.5 to 2 times more than dual-screen splicing solutions. This high cost limits their adoption in mid-to-low-end vehicles, especially in an increasingly competitive market where OEMs need to strike a balance between cost control and user experience. 2) Traditional dual-screen or triple-screen splicing solutions typically use multiple display modules, but due to technological limitations, the black borders at the splicing points are quite wide. Currently, the black border width of most splicing screens on the market is 15 mm or more, resulting in a lack of seamless connection between screens and a poor visual effect. This noticeable black border not only affects the overall aesthetics but also reduces the user's immersive experience, especially when displaying cross-screen content, where the presence of the black border disrupts the continuity of the image. 3) Traditional dual-screen or triple-screen splicing solutions structurally equip each display module with an independent mounting bracket and add a decorative shell to fix and protect the screen. This design results in a thicker screen, which not only takes up more interior space but also increases the complexity of the interior design. Furthermore, the thicker screen structure may also affect the efficiency of interior space utilization, especially in modern car interiors that strive for a slimmer design, where this issue is particularly prominent.

[0005] In summary, although multi-screen and large-screen designs have become the development trend of automotive displays, existing technologies still have many shortcomings in terms of cost, display effect, and structural design. Therefore, how to achieve narrower bezels, thinner screens, and better display effects without significantly increasing costs has become a key issue that urgently needs to be addressed in the field of automotive display technology. This patent aims to overcome the limitations of existing technologies through an innovative design, providing a lower-cost, higher-performance, and thinner automotive display solution.

Detailed Implementation

[0045] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0046] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0047] Numerous details are explored in the following description to provide a more thorough explanation of embodiments of this application; however, it will be apparent to those skilled in the art that embodiments of this application may be implemented without these specific details.

[0048] This utility model aims to disclose an integrated backlight shell, backlight assembly, dual screens, and vehicle, in order to solve the problem of wide black borders in the splicing of traditional display module dual screens. It can also solve the problems of no through-effect display, thick thickness, and poor user experience in the splicing of traditional display module dual screens, as well as the high cost of existing integrated large screens.

[0049] Among them, such as Figures 1 to 11 As shown, the integrated backlight housing includes: an integrated backlight housing body 1, and a partition wall 11 is formed in the middle of the integrated backlight housing body 1 to separate the central control backlight assembly 2 from the passenger backlight assembly 3.

[0050] In some embodiments, a partition wall 11 is formed in the middle of the integrated backlight housing 1 to separate the light sources of the central control backlight assembly 2 and the passenger backlight assembly 3.

[0051] By setting a partition wall 11 on the integrated backlight housing 1 to separate the light sources of the central control backlight assembly 2 and the passenger backlight assembly 3, the width of the splicing black border is effectively reduced, solving the problem of wide splicing black borders in traditional display module splicing dual screens, making the display screen more coherent and beautiful, and improving the user experience.

[0052] Furthermore, traditional dual-screen displays require the separate assembly of two independent backlight components before splicing, resulting in complex processes and high precision requirements. In contrast, the integrated backlight housing in this embodiment integrates the central control backlight component 2 and the passenger-side backlight component 3 into a single housing, reducing assembly steps and complexity, and improving production efficiency. The partition wall 11 not only separates the light sources but also enhances the rigidity of the overall housing, improving product durability. The design of the partition wall 11 allows for precise control of the light source distribution of the central control backlight component 2 and the passenger-side backlight component 3, preventing mutual interference and ensuring uniform brightness in both areas. The integrated backlight housing features a one-piece molding design, resulting in a more robust structure and avoiding structural loosening or deformation issues that may occur with traditional splicing methods. The integrated backlight housing reduces redundant structural components found in traditional splicing methods, making the overall design more compact and facilitating a thinner and lighter device design. The integrated backlight housing design in this embodiment is more suitable for high-end display needs, such as automotive displays and high-end televisions, providing a seamless and continuous visual effect to meet users' requirements for high-quality displays.

[0053] In some embodiments, the thickness of the partition wall 11 is less than or equal to 1 mm.

[0054] In some embodiments, in order to buffer the central control lower diffuser film 24 and central control lower brightness enhancement film 25 in the central control backlight assembly 2, and the passenger lower diffuser film 34 and passenger lower brightness enhancement film 35 in the passenger backlight assembly 3, so as to avoid friction damage to the film material between the film material and the partition wall, a buffer adhesive 12 is provided on the partition wall 11 to ensure the service life of the central control backlight assembly 2 and the passenger backlight assembly 3.

[0055] For example, the partition wall 11 is provided on the front of the integrated backlight housing body 1. One side wall of the partition wall 11 is provided with a small protrusion feature. The top of the partition wall 11 is provided with a buffer adhesive 12, which is foam adhesive. The buffer adhesive 12 is provided with a first fixing protrusion 13 for fixing the integrated upper brightness enhancement film 4.

[0056] In some embodiments, to improve the stability of the integrated backlight housing body 1, a mounting bracket 14 is formed on the integrated backlight housing body 1. This also reduces the need for mounting bracket molds and lowers mold opening costs.

[0057] For example, three mounting brackets 14 are formed on the upper part of the back of the integrated backlight housing body 1, and one mounting bracket 14 is formed on the lower part. During installation, the four mounting brackets 14 are inserted into the corresponding positions of the instrument panel frame, and then screws are tightened to fix them, which is stable and reliable.

[0058] In some embodiments, in order to reduce the width of the black borders at the top and bottom of the dual-screen display and make it more aesthetically pleasing, a backlight cable opening 15 and a display cable opening 16 are provided on the integrated backlight housing body 1.

[0059] For example, the upper part of the back of the integrated backlight housing 1 has two backlight cable openings 15, and the lower part has four display cable openings 16. The flexible backlight cable for the central control unit and the flexible backlight cable for the passenger side are connected to the central control PCBA and the passenger side PCBA respectively through a backlight cable opening 15. The flexible cable for the central control display screen and the flexible cable for the passenger side display screen are connected to the central control PCBA and the passenger side PCBA respectively through two display cable openings 16.

[0060] The partition wall 11 and the mounting bracket 14 are both integrally formed on the integrated backlight housing body 1. The front of the integrated backlight housing body 1 refers to the side used to install the central control backlight assembly 2 and the passenger backlight assembly 3, and the back refers to the side used to fix or connect other components. The upper part of the back also serves as the appearance surface, eliminating the plastic back cover, making the screen thinner and lighter.

[0061] For example, the integrated backlight housing 1 is integrally formed using a metal die-casting process, and the material is selected as magnesium-aluminum alloy, which can both ensure the strength of the installation structure and reduce the weight.

[0062] In some embodiments, a backlight assembly is also provided, including an integrated backlight housing as described in any of the above embodiments. The integrated backlight housing body 1 is provided with a central control backlight assembly 2 and a passenger backlight assembly 3, and an integrated brightness enhancement film 4 is provided on the central control backlight assembly 2 and the passenger backlight assembly 3.

[0063] In traditional designs, the brightness enhancement film typically covers two separate backlight components, which can easily lead to inconsistent brightness or dark areas at the seams. The integrated design avoids this problem. In this embodiment, the integrated backlight housing, with an integrated upper brightness enhancement film 4 covering the central control backlight component 2 and the passenger-side backlight component 3, can improve the overall backlight brightness while ensuring uniform light distribution.

[0064] In traditional designs, the brightness enhancement film needs to be cut and spliced ​​at the seams, which can easily create gaps or light loss, affecting the display effect. However, the integrated brightness enhancement film 4 in this embodiment covers the entire backlight area, eliminating splicing gaps, making the display image more continuous, and improving the user experience. Furthermore, in traditional designs, light loss at the splicing points is significant, while the integrated brightness enhancement film 4 in this embodiment can utilize the backlight more efficiently, reducing light loss, lowering energy consumption, and improving overall light efficiency.

[0065] The integration of the integrated brightness enhancement film 4 with the integrated backlight shell reduces the steps of splicing multiple brightness enhancement films in traditional designs, simplifying the assembly process. It also enhances the overall structural stability, avoiding loosening or deformation issues caused by splicing brightness enhancement films in traditional designs. Furthermore, it meets the high requirements of high-end display devices for brightness, uniformity, and visual effects.

[0066] In addition, the integrated design makes the backlight assembly look cleaner, avoiding gaps or irregular edges that may exist in traditional splicing methods, thus improving the product's aesthetics.

[0067] In some embodiments, the central backlight assembly 2 includes a central reflective paper 21, a central light strip 22, a central light guide plate 23, a central lower diffuser film 24, and a central lower brightness enhancement film 25 arranged sequentially.

[0068] In some embodiments, the passenger-side backlight assembly 3 includes a passenger-side reflective paper 31, a passenger-side light strip 32, a passenger-side light guide plate 33, a passenger-side lower diffuser film 34, and a passenger-side lower brightness enhancement film 35 arranged sequentially.

[0069] For example, the center console lower diffuser 24, the center console lower brightness enhancement film 25, the passenger side lower diffuser 34, and the passenger side lower brightness enhancement film 35 are supported by the partition wall 11 on the integrated backlight housing body 1 to ensure the stability of the center console lower diffuser 24, the center console lower brightness enhancement film 25, the passenger side lower diffuser 34, and the passenger side lower brightness enhancement film 35.

[0070] In some embodiments, the central control light guide plate 23 is provided with a second fixing boss 231 for fixing the integrated upper brightness enhancement film 4, the central control lower diffusion film 24 and the central control lower brightness enhancement film 25.

[0071] For example, the central light guide plate 23 has a second fixing boss 231 formed in the middle of its length direction, which is used to fix the integrated upper brightness enhancement film 4, the central lower diffusion film 24 and the central lower brightness enhancement film 25.

[0072] The integrated upper brightness enhancement film 4, the central control lower diffusion film 24, and the central control lower brightness enhancement film 25 all have openings at positions corresponding to the second fixing boss 231. In the assembly process, the central control lower diffusion film 24, the central control lower brightness enhancement film 25, and the integrated upper brightness enhancement film 4 are stacked on the central control light guide plate 23 in sequence and fixed by the second fixing boss 231.

[0073] In some embodiments, the passenger-side light guide plate 33 is provided with a third fixing boss for fixing the integrated upper light enhancement film 4, the passenger-side lower diffuser film 34 and the passenger-side lower light enhancement film 35.

[0074] For example, the passenger-side light guide plate 33 has a third fixing boss formed at the middle of its length direction, which is used to fix the integrated upper brightness enhancement film 4, the passenger-side lower diffusion film 34 and the passenger-side lower brightness enhancement film 35.

[0075] The integrated upper light enhancement film 4, the passenger side lower diffuser film 34, and the passenger side lower light enhancement film 35 all have openings at positions corresponding to the third fixing boss. In the assembly process, the passenger side lower diffuser film 34, the passenger side lower light enhancement film 35, and the integrated upper light enhancement film 4 are stacked on the passenger side light guide plate 33 in sequence and fixed by the third fixing boss.

[0076] In some embodiments, the integrated brightening film 4 is provided with a middle sheet metal 5, and the middle sheet metal 5 is provided with foam 6.

[0077] For example, the central control backlight assembly 2 and the passenger backlight assembly 3, as well as the integrated brightening film 4 and the central sheet metal 5 are sequentially fixed on the front of the integrated backlight housing body 1. The central sheet metal 5 is fixed in the front edge slot of the integrated backlight housing body 1 by a snap-fit, thereby fixing the backlight assembly. Foam 6 is provided between the central sheet metal 5 and the integrated backlight housing body 1.

[0078] In some embodiments, a dual-screen setup is also provided, including the backlight component from any of the above embodiments.

[0079] In some embodiments, the dual-screen configuration includes a glass cover 7, an adhesive 8, a display screen 9, a backlight assembly, a PCBA assembly 10, and a decorative cover 20 arranged sequentially.

[0080] For example, the adhesive 8 is optical adhesive (OCA). The glass cover 7 is optically bonded to the central control display screen 91 and the passenger-side display screen 92 using optical adhesive to form a bonded display screen assembly. The display screen assembly is then assembled and fixed to the backlight assembly using an adhesive dispensing process.

[0081] For example, the display screen 9 includes a central control display screen 91 and a passenger-side display screen 92.

[0082] Among them, the central control display screen 91 is the central control FOG, and the passenger display screen 92 is the passenger FOG. FOG stands for FPC ONGLASS, which is a professional term in the field of electronic display. It usually refers to the technology of directly bonding or integrating flexible printed circuit (FPC) onto a glass substrate. It is mainly used in high-precision display modules (such as OLED screens, automotive displays, etc.).

[0083] By using FOG to replace the display module for dual-screen splicing, and combining it with the aforementioned integrated backlight shell and integrated brightness enhancement film, a good effect of splicing black border ≤6mm (gap between two FOGs ≤1mm) can be achieved, further reducing the splicing black border of dual screens. Compared with traditional display module splicing, the through effect is better, and it can be combined with UI design to provide a better interactive experience.

[0084] The central control display screen 91 and the passenger-side display screen 92 can be the same or different sizes of display screens.

[0085] For example, PCBA component 10 includes central control PCBA component 101 and passenger PCBA component 102.

[0086] For example, both the central control PCBA assembly 101 and the passenger-side PCBA assembly 102 are fixed to the back of the integrated backlight housing 1 by fasteners. The central control PCBA assembly 101 and the passenger-side PCBA assembly 102 are the same PCBA assembly.

[0087] For example, the decorative cover 20 is provided with a positioning post 201 and a pre-fixing buckle 202.

[0088] For example, the decorative cover 20 is fixed to the back of the integrated backlight shell body 1 by screws 30. On the left and right sides of the back of the decorative cover 20 near the bottom, there is a positioning post 201 and a pre-fixing buckle 202. The material of the decorative cover 20 is PC+ABS.

[0089] During assembly, insert the positioning post 201 and the pre-fixing buckle 202 into the corresponding opening of the instrument panel frame, and then push the dual screen into the instrument panel to accurately position and pre-fix the dual screen to the instrument panel.

[0090] In some embodiments, a vehicle is also provided, which is equipped with the dual screens of any of the above embodiments.

[0091] In summary, this utility model's integrated backlight housing, by incorporating a partition wall on the integrated backlight housing body to separate the light sources of the central control backlight assembly and the passenger-side backlight assembly, effectively reduces the width of the black border between the panels. This solves the problem of wide black borders in traditional dual-screen display module splicing, resulting in a more continuous and aesthetically pleasing display and improved user experience. The partition wall not only separates the light sources but also enhances the rigidity of the overall housing, improving product durability. Furthermore, the integrated backlight housing adopts a one-piece molding design, making the structure more robust and avoiding potential structural loosening or deformation issues associated with traditional splicing methods. It also reduces unnecessary structural components in traditional splicing methods, resulting in a more compact overall design that facilitates the slimming and lightweight design of the device.

[0092] This utility model's backlight assembly, by employing a one-piece backlight shell and an integrated upper brightness enhancement film covering the central control backlight assembly and the passenger-side backlight assembly, effectively improves the overall backlight brightness while ensuring uniform light distribution. The combination of the integrated upper brightness enhancement film and the one-piece backlight shell reduces the steps of splicing multiple brightness enhancement films in traditional designs, simplifying the assembly process. The integrated upper brightness enhancement film covers the entire backlight area, eliminating splicing gaps, making the display image more continuous, and improving the user experience. It has significant application value in the field of automotive display technology.

[0093] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
