[0001] This utility model mainly relates to the technical field of vehicle-mounted displays, specifically to a wood grain display module. Background Technology

[0002] With the rapid development of the automotive industry, especially new energy vehicles, car interior design is increasingly focusing on intelligence and aesthetics. While traditional large-screen display devices are powerful, they can sometimes disrupt the overall look and aesthetics of the interior. Therefore, the in-vehicle wood grain decorative cover module display structure has emerged. When not in use, this design resembles a piece of wood veneer, seamlessly integrating with the car's interior for a pleasing and elegant appearance; when in use, it can display driving information and other data, combining practicality and aesthetics.

[0003] Some wood grain modules, such as those used for display screen decoration, have limited light transmittance, resulting in a duller, less bright, and less clear decorative effect. In applications where light transmission is required to display patterns, text, or lighting effects, such as automotive dashboard trim, lower light transmittance can negatively impact the display quality of those patterns, text, or lights.

[0022] This application provides a wood grain display module, as shown in the schematic diagram below. Figure 1 As shown. The wood grain display module includes a wood grain cover plate 10, optical transparent adhesive 20, flexible circuit board bonding glass 30, ultra-strong acrylic foam tape 40, backlight module 50, and back plate 60. The wood grain cover plate 10 is bonded to the flexible circuit board bonding glass 30 via optical transparent adhesive 20. The flexible circuit board bonding glass 30 is connected to the backlight module 50 via ultra-strong acrylic foam tape 40. The backlight module 50 is connected to the back plate 60 via another layer of ultra-strong acrylic foam tape 40. The wood grain cover plate 10 is located on the outermost layer of the module and is used to display the wood grain appearance and has light transmission. The back plate 60 is located on the innermost layer of the module and is used to support and protect the internal structure.

[0023] It should be noted that in this embodiment, by clearly defining the component numbers, connection relationships, and positional relationships, the overall architecture of the wood grain display module is clearly constructed. The labels help to accurately describe and understand the functions and collaborative methods of each component. The wood grain cover plate 10 is located on the outermost layer; its labeling facilitates identification, effectively showcases the wood grain appearance, enhances the product's aesthetics, and its light transmittance provides a foundation for the display function. The back plate 60 is located on the innermost layer; its labeling clarifies its position within the structure, providing stable support and protection for internal components such as the optically transparent adhesive 20, flexible circuit board bonding glass 30, ultra-strong acrylic foam tape 40, and backlight module 50, preventing internal components from being interfered with or damaged by external factors, thus ensuring the overall stability and reliability of the module.

[0024] Optionally, such as Figure 1 As shown, the thickness of the wood grain cover plate is between 0.5 and 3 mm.

[0025] In this embodiment, the thickness of the wood grain cover plate 10 is limited to 0.5-3 mm, which balances strength and light transmittance. On the one hand, this makes the wood grain cover plate 10 less prone to deformation or damage due to external forces, ensuring the integrity of the module structure; on the other hand, good light transmittance can reduce the obstruction of light propagation, allowing the light emitted by the backlight module 50 to pass through more effectively, improving the clarity and brightness of the display screen, and optimizing the user's visual experience.

[0026] Optionally, such as Figure 1 As shown, optically transparent adhesive 20 is a substrate-free double-sided adhesive with a thickness between 0.05 and 0.5 mm and a light transmittance of not less than 95%.

[0027] In this embodiment, the use of a substrate-free double-sided adhesive 20, with a thickness of 0.05-0.5 mm and a light transmittance of not less than 95%, is of great significance. The substrate-free design reduces light obstruction, the appropriate thickness ensures adhesion, allowing the wood grain cover 10 to be tightly bonded to the flexible circuit board bonding glass 30, and the high light transmittance greatly reduces light loss, making the displayed colors more vivid and realistic, effectively improving the display effect.

[0028] Optionally, such as Figure 1 As shown, the flexible circuit board in the flexible circuit board bonding glass 30 is bonded to the glass substrate by a hot pressing process, and multiple signal transmission lines are provided on the flexible circuit board.

[0029] In this embodiment, the flexible circuit board in the flexible circuit board bonding glass 30 is bonded to the glass substrate by a hot-pressing process, and is provided with multiple signal transmission lines. The hot-pressing process ensures a stable connection, and the multiple signal transmission lines can accurately and efficiently transmit display signals, ensuring accurate presentation of the displayed content, avoiding display errors, screen distortion, and other problems, and improving the reliability and accuracy of the module's display function.

[0030] Optionally, such as Figure 1 As shown, the foam thickness of the Super Strong Acrylic Foam Tape 40 is between 0.1 and 1 mm.

[0031] In this embodiment, the 0.1-1 mm thickness of the ultra-strong acrylic foam tape 40 gives it excellent adhesion and cushioning properties. Good adhesion ensures a firm connection between components such as the flexible circuit board bonding glass 30 to the backlight module 50, and the backlight module 50 to the backplate 60, preventing loosening even under vibration. The cushioning properties effectively absorb external vibrations and impacts, protecting internal components from damage, extending module lifespan, and enhancing its adaptability to complex environments.

[0032] Optionally, such as Figure 1As shown, the backlight module 50 includes a light source, a light guide plate, a reflective sheet, and a diffuser sheet. The light source is located on one side of the light guide plate, the reflective sheet is located below the light guide plate, and the diffuser sheet is located above the light guide plate, which is used to provide a uniform backlight.

[0033] In this embodiment, the backlight module 50 includes a light source, a light guide plate, a reflective sheet, and a diffuser sheet. The positions of each component are rationally designed: the light source is located on one side of the light guide plate, the reflective sheet is located below the light guide plate, and the diffuser sheet is located above the light guide plate. This structure allows the light emitted by the light source to uniformly illuminate the display area after synergistic interaction, avoiding uneven brightness in the displayed image, greatly improving the display quality, making the displayed content clearer and easier to read, and providing users with a good visual experience.

[0034] Optionally, such as Figure 1 As shown, the backplate 60 has an anti-oxidation layer on its surface, and multiple heat dissipation holes and mounting holes are provided on the backplate.

[0035] In this embodiment, the anti-oxidation layer on the surface of the backplate 60 can prevent it from being oxidized and corroded, extend the service life of the backplate, and thus ensure the long-term stable operation of the entire module; the heat dissipation holes on the backplate 60 can dissipate the heat generated by the module in a timely manner, avoiding the degradation or damage of the component performance due to overheating; the mounting holes facilitate the installation and connection of the module with external equipment, improve the convenience and efficiency of installation, and enable the module to better adapt to different application scenarios.

[0036] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
