Description

Technical Field

[0001] The utility model relates to the technical field of display modules, and more particularly to a vibration-resistant display module. Background Art

[0002] Display modules are widely used in vehicles such as motorcycles and automobiles. However, due to the complexity of road conditions, these vehicles are inevitably subject to bumps during driving. Frequent and severe bumps often lead to display problems, such as black spots and starry sky on the screen. These problems not only affect the driver's visual experience but also shorten the service life of the display module. Currently, the structure commonly used in display modules is: the cover plate and the display screen are fully bonded using OCA, and the backlight module and the display screen are bonded with foam. At the same time, the cover plate is bonded to the customer's end product with foam (or glue) around the perimeter. A rivet structure is also provided behind the backlight module, and the screw holes in the rivets secure it to the customer's end product. However, this structure is inadequate for high vibration and shock standards (such as the 35G shock standard required for automobiles and motorcycles).

[0003] The impact of road bumps is transmitted through the vehicle's computer to the display module's rivets or the cover's foam, and then to the LCD screen. Rivets are rigid and therefore ineffective at cushioning the impact. While foam adhesive does have some cushioning effect, its high compression ratio prevents it from effectively absorbing and dissipating the force of large bumps. This results in significant shortcomings in the existing display module structure's resistance to shock and vibration. Therefore, we have developed a vibration-resistant display module to address this issue. Utility Model Content

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this utility model belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. Reference to "embodiments" herein means that the specific features, structures or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the utility model. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] As described in the background art, the current structure commonly used in display modules is as follows: the cover plate and the display screen are fully bonded using OCA, and the backlight module and the display screen are bonded using foam. Simultaneously, the cover plate is bonded to the customer's end product using foam (or glue) on all sides. A rivet structure is also provided behind the backlight module, and is secured to the customer's end product via screw holes in the rivets. However, this structure is inadequate when faced with high-standard vibration and shock (such as the 35G shock standard required for automobiles or motorcycles). The impact caused by road bumps is transmitted through the vehicle computer to the rivets of the display module or the foam of the cover plate, and then to the LCD screen. Because the rivets are made of rigid material, they cannot provide a cushioning effect. While foam glue has a certain cushioning effect, its high compression ratio makes it unable to effectively absorb and disperse the impact force when faced with large bumps and shocks. As a result, the existing display module structure has obvious deficiencies in vibration and shock resistance.

[0028] In order to solve this technical problem, the utility model provides a vibration-resistant display module.

[0029] Specifically, please refer to Figure 1-Figure 2 , the anti-vibration display module specifically includes:

[0030] The cover plate body 1 is provided with an adhesive portion 2 , which includes a second double-sided adhesive 203 bonded to the cover plate body 1 , and a first anti-vibration component is connected to the side of the second double-sided adhesive 203 away from the cover plate body 1 .

[0031] The utility model provides a vibration-resistant display module. The adhesive portion 2 is set in the present application. The first vibration-resistant component in the adhesive portion 2 can reduce the transmission of vibration of the terminal product to the cover plate main body 1 during use, thereby significantly improving the vibration and impact resistance of the present application. By enhancing the vibration and impact resistance of the present application, it can effectively reduce display problems caused by bumps and impacts, such as the occurrence of black spots, stars, etc., which not only improves the driver's visual experience, but also significantly extends the service life of the display module.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] Embodiment 1 of the vibration-resistant display module of the present invention

[0036] Please refer to Figure 1-Figure 2 The anti-vibration display module of the present invention includes: a cover plate main body 1, an adhesive portion 2 is provided on the cover plate main body 1, the adhesive portion 2 includes a second double-sided adhesive 203 bonded to the cover plate main body 1, and the second double-sided adhesive 203 is connected to a first anti-vibration component on the side away from the cover plate main body 1; by providing the first anti-vibration component, the vibration of the terminal product during use can be effectively reduced from being transmitted to the cover plate main body 1, greatly improving the anti-vibration and impact performance. This is because the first anti-vibration component can serve as a buffer layer. When the terminal product vibrates, it can absorb and disperse a large amount of vibration energy, significantly reducing the vibration amplitude transmitted to the cover plate main body 1, providing effective protection for the cover plate main body 1, and reducing the risk of damage to the cover plate main body 1 or performance degradation due to vibration.

[0037] Further, such as Figure 1-Figure 2 As shown, the first shock-resistant component is a rubber pad 201, and the rubber pad 201 is pasted on the side of the second double-sided adhesive 203 away from the cover body 1. With the help of the shock-resistant performance of the rubber pad 201, the shock-resistant impact performance of the present application is significantly improved; the shock-resistant performance of the rubber pad 201 is utilized to further enhance the shock-resistant impact performance, making the display module more stable and reliable in a complex use environment. Rubber has excellent elasticity and damping properties, and can effectively absorb and buffer vibration energy. It is used as the first shock-resistant component. When encountering vibration, the rubber pad 201 can deform rapidly, converting the vibration energy into its own elastic potential energy, and then slowly release it, thereby greatly reducing the vibration energy transmitted to the cover body 1, further improving the shock resistance of the display module, and reducing the occurrence rate of failures caused by vibration.

[0038] Further, such as Figure 1-Figure 2 As shown, the adhesive portion 2 also includes a first double-sided adhesive 202, which is connected to the side of the rubber pad 201 away from the second double-sided adhesive 203. The addition of the first double-sided adhesive 202 not only facilitates the bonding with the customer's terminal product, but also makes the connection more firm and stable, ensuring the safety and reliability of the display module during use. The first double-sided adhesive 202 can make the rubber pad 201 fit tightly with the terminal product without leaving any gaps, while ensuring the shock-resistant effect, greatly enhancing the stability of the connection. Even if it is subjected to external force impact or long-term use, the display module will not be easily separated from the terminal product, effectively avoiding display anomalies or other failures caused by loose connections, improving the overall stability and reliability, and providing users with a more reassuring experience.

[0039] Further, such as Figure 1As shown, the adhesive portion 2 is arranged in a frame shape, and the adhesive portion 2 is used to realize the connection between the cover body 1 and the terminal product. The frame-shaped arrangement can improve the sealing after the connection, effectively prevent impurities such as dust and water vapor from entering the interior of the display module, and provide a good environmental protection for the normal operation of the display module. In actual use, dust and water vapor are common factors that cause electronic equipment failures. Good sealing can isolate the interior of the display module from the external environment, avoid dust from entering and accumulating on the surface of the component to affect heat dissipation and electrical performance, and prevent water vapor from entering and causing short circuits, corrosion and other problems. This not only ensures the normal operation of the display module and extends its service life, but also improves its adaptability and reliability in various harsh environments.

[0040] Embodiment 2 of the vibration-resistant display module of the present invention

[0041] The anti-vibration display module of the present invention is further characterized as follows: Figure 1 As shown, a glue frame 101 and a backlight assembly 103 located in the glue frame 101 are provided on one side of the cover body 1 close to the second double-sided adhesive 203, a display screen assembly is provided on one side of the backlight assembly 103 close to the cover body 1, and the display screen assembly is connected to the main screen FPC 104, and the main screen FPC 104 passes through the backlight assembly 103 and one side of the glue frame 101 and is bent at the back of the backlight assembly 103.

[0042] Further, such as Figure 1 As shown, a backlight FPC 105 is connected between the backlight assembly 103 and the main screen FPC 104. The connection through the backlight FPC 105 ensures stable and reliable signal transmission, providing a solid guarantee for the display effect. In the display module, the stability of signal transmission directly affects the quality of the displayed image. The backlight FPC 105 can efficiently transmit signals, allowing smooth communication between the backlight assembly 103 and the main screen FPC 104, providing stable backlight support for the display. In this way, the display can accurately display images and text, avoiding problems such as screen flickering and color distortion caused by unstable signal transmission, ensuring the high quality and stability of the displayed image, and providing users with a good visual experience.

[0043] Further, such as Figure 1 As shown, an FPC connector 106 is provided on the main screen FPC 104, and the FPC connector 106 cooperates with the main screen FPC 104 to realize the connection between the display screen assembly and the terminal product; the setting of the FPC connector 106 facilitates the connection between the display screen assembly and the terminal product, greatly improving the convenience and reliability of the connection.

[0044] Embodiment 3 of the vibration-resistant display module of the present utility model

[0045] The anti-vibration display module of the present invention is further characterized as follows: Figure 1 and Figure 3 As shown, a plurality of rivet bodies 3 are provided on the side of the backlight assembly 103 away from the cover body 1, and the rivet bodies 3 are used to achieve connection with the terminal product; the setting of the rivet bodies 3 makes the connection between the backlight assembly 103 and the terminal product more firm and reliable, significantly enhances the stability of the overall structure, and provides a solid foundation for the normal operation of the display module. The rivet connection has high strength and reliability and can withstand large tensile and shear forces. During use, even if it encounters external force impact or vibration, the structure of the display module will not be deformed or the function is abnormal due to loosening, which effectively improves the impact resistance and durability of the display module and ensures its stable operation in various complex environments.

[0046] Furthermore, a second anti-vibration component is provided on the outer surface of the rivet body 3, and the second anti-vibration component is in contact with the side of the backlight assembly 103 away from the cover body 1. The second anti-vibration component is provided to further absorb vibration energy, which significantly improves the anti-vibration performance of the display module, so that it can still maintain good performance in harsh working environments. When the display module is vibrated, the second anti-vibration component can buffer and absorb the vibration again on the basis of the rivet connection. It can disperse the vibration energy to a larger area, reduce the impact on the backlight assembly 103 and the entire display module, further improve the anti-vibration ability of the display module, reduce the risk of damage to internal components or loose connections due to vibration, and extend the service life of the display module.

[0047] Further, such as Figure 1 、 Figure 3 and Figure 4 As shown, the second shock-resistant component is a rubber ring 301, which is fixedly mounted on the outer surface of the rivet body 3, and the rubber ring 301 contacts the side of the backlight assembly 103 away from the cover body 1, and utilizes the elastic properties of the rubber material to absorb and disperse the impact force, thereby significantly improving the vibration and impact resistance of the display module.
