Description

Technical Field

[0001] This utility model relates to the field of LCM liquid crystal display module technology, specifically to an LCM liquid crystal display module with simplified ribbon cable connection. Background Technology

[0002] LCM, or Liquid Crystal Display Module, is a fully functional display unit integrated with components such as a liquid crystal display screen, driving circuitry, backlight, and structural components. Its core function is to combine the driving circuitry with the liquid crystal panel, receiving signals through a driver IC and converting them into voltage waveforms to control the display. Users only need to provide power and commands to achieve content output.

[0003] For example, utility model application CN201921534268.8 discloses an electric clamp-type cold-cutting flying saw. This electric clamp-type cold-cutting flying saw uses a drive gear, a driven gear, a first motor, a first flying saw gear, and a second flying saw gear to achieve flexible up-and-down movement of the flying saw gear. At the same time, the interval between the first and second flying saw gears is used to achieve quantitative flying sawing, which improves the mass production and flexibility of the electric clamp-type cold-cutting flying saw. However, similar cold-cutting flying saws in the above-mentioned documents do not have a corresponding structure to assist the saw in stable displacement while working. When the equipment is in operation, it does not have an automatic feeding structure, which is lacking in overall efficiency and practicality. Utility Model Content

[0004] The purpose of this invention is to provide an LCM liquid crystal display module that simplifies cable connection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LCM liquid crystal display module with simplified cable connection, comprising a liquid crystal display component and a protective film component. The outer surface of the liquid crystal display component is covered with the protective film component, and a protective frame is fixedly connected to the edge of the liquid crystal display component. Furthermore, a heat sink is covered on the rear surface of the liquid crystal display component, and an FPC interface cable is installed on one end of the heat sink near the edge. At the same time, the surface of the FPC interface cable is coated with a wear-resistant coating.

[0006] Furthermore, the liquid crystal display component includes a liquid crystal screen driving base layer, a backlight layer, a liquid crystal screen body, and a protective layer. The backlight layer is horizontally disposed on the top surface of the liquid crystal screen driving base layer, and the liquid crystal screen body is horizontally disposed on the top surface of the backlight layer. Moreover, the protective layer is disposed on the side surface of the liquid crystal screen body away from the backlight layer.

[0007] Furthermore, the liquid crystal display driving base layer and the backlight layer are integrated and combined using the same module, and the assembly complexity is reduced by pre-connected cabling. The protective layer uses an anti-reflective coating such as AR coating to reduce ambient light reflectivity.

[0008] Furthermore, the protective film component includes a base film layer, a diffuser layer, and a prism sheet layer. The top surface of the base film layer is provided with a diffuser layer, and the top surface of the diffuser layer is coated with a prism sheet layer.

[0009] Furthermore, the protective frame is made of glass fiber reinforced nylon, and the gap between the protective frame and the liquid crystal display component is filled and bonded with UV-cured protective adhesive.

[0010] Furthermore, the FPC interface cable adopts a standardized interface structure, and a magnetic ring or metal shielding layer is installed inside the FPC interface cable, with a filter capacitor connected in parallel on the key signal lines to suppress electromagnetic interference.

[0011] Furthermore, the outer surface of the heat sink is coated with a heat dissipation coating, and a support base is fixedly connected to each of the four opposite corners of the heat sink.

[0012] Furthermore, the heat sink is made of thermally conductive silicone grease, and the heat dissipation coating is made of conductive silver paste.

[0013] This utility model provides an LCM liquid crystal display module that simplifies the ribbon cable connection, and has the following beneficial effects: 1. This utility model simplifies and enhances the durability of the ribbon cable by incorporating an FPC interface cable and a wear-resistant coating. The FPC interface cable adopts a standardized interface structure, which not only facilitates production and maintenance but also effectively suppresses electromagnetic interference and ensures signal transmission stability through the internal magnetic ring or metal shielding layer and parallel filter capacitors. Furthermore, the wear-resistant coating significantly extends the cable's lifespan, reducing the cost and time associated with frequent cable replacements. The FPC interface cable itself is also meticulously designed with excellent flexibility, maintaining a stable electrical connection even when the module is subjected to slight vibration or bending, thus avoiding poor contact due to physical deformation. This characteristic makes the LCM liquid crystal display module perform exceptionally well in applications requiring frequent movement or operating in vibration environments, such as automotive display systems and portable electronic devices. This greatly expands the product's application scenarios and reliability, while also simplifying cable connections and lowering the technical barriers to assembly and maintenance.

[0014] 2. This utility model integrates the LCD screen driving base layer and backlight layer into a single module, reducing assembly complexity and improving production efficiency through pre-connected cabling. Furthermore, the anti-reflective coating, such as AR coating, used in the protective layer effectively reduces ambient light reflectivity, enhancing display performance and providing users with a clear visual experience under various lighting conditions. Simultaneously, the use of a protective film component, composed of a base film layer, a diffuser layer, and a prism sheet layer, not only enhances the protective performance of the LCD module but also, through the combined use of the diffuser and prism sheet layers, effectively improves light distribution, increasing the brightness and contrast of the LCD module. This technology brings users a superior visual experience while reducing light scattering and improving display uniformity. The base film layer serves as a fundamental support, providing a stable attachment platform for the upper structure. The diffuser layer, through its special microstructure, scatters light as it passes through, thereby expanding the light distribution range and improving the overall brightness of the LCD module. The prism sheet layer, with its prism structure, precisely guides and focuses light, further enhancing the contrast and color saturation of the LCD module. This synergistic effect of the multi-layer structure significantly improves the display effect of the LCD module, meeting users' demands for high-quality displays.

[0015] 3. This utility model utilizes a glass fiber reinforced nylon protective frame, a material known for its high strength and lightweight properties, effectively protecting the LCD components from external impacts. Furthermore, the gap between the protective frame and the LCD components is filled with UV-cured protective adhesive, further enhancing the overall structural stability and ensuring the safety of the LCD module during use. The uniquely designed heat sink, made of thermally conductive silicone grease, possesses excellent thermal conductivity, quickly dissipating heat generated by the LCD components. The heat dissipation coating on the outer surface of the heat sink is made of conductive silver paste, further improving heat dissipation efficiency. Supports are fixedly connected at each of the four diagonal corners of the heat sink, making it more stable and reliable during installation and use. It also functions as a static electricity discharge device, effectively preventing static electricity from damaging the LCD components, further enhancing the stability and reliability of the LCD module. This comprehensive protection and heat dissipation design allows the LCM LCD module to maintain excellent performance even under prolonged high-load operation, extending product lifespan and reducing maintenance costs.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 4 As shown, a simplified LCM liquid crystal display module with ribbon cable connection includes a liquid crystal display component 1 and a protective film component 2. The outer surface of the liquid crystal display component 1 is covered with the protective film component 2, and a protective frame 3 is fixedly connected to the edge of the liquid crystal display component 1. A heat sink 4 is covered on the rear surface of the liquid crystal display component 1, and an FPC interface ribbon cable 5 is mounted on one end of the heat sink 4 near its edge. The surface of the FPC interface ribbon cable 5 is coated with a wear-resistant coating 6. The FPC interface ribbon cable 5 adopts a standardized interface structure, and a magnetic ring or metal shielding layer is added inside the FPC interface ribbon cable 5, with a filter capacitor connected in parallel on key signal lines to suppress electromagnetic interference. The standardized interface structure is used to achieve this. This enables the FPC interface cable 5 to connect quickly and stably to various devices, greatly improving the compatibility and interchangeability of the devices. Whether in the production process or in the subsequent maintenance and replacement process, it can significantly reduce the difficulty of operation and time costs. In addition, the wear-resistant coating 6 sprayed on the surface of the FPC interface cable 5 also plays a crucial role. In daily use, the cable often wears down due to frequent plugging and unplugging, friction or environmental factors, and may even break. This not only affects the normal use of the equipment, but may also cause safety hazards. The presence of the wear-resistant coating 6 can effectively resist the corrosion of these external factors, extend the service life of the cable, and reduce the maintenance and replacement costs caused by cable damage.

[0020] like Figures 1 to 4As shown, the liquid crystal display component 1 includes a liquid crystal screen driving base layer 101, a backlight layer 102, a liquid crystal screen body 103, and a protective layer 104. The backlight layer 102 is horizontally disposed on the top surface of the liquid crystal screen driving base layer 101, and the liquid crystal screen body 103 is horizontally disposed on the top surface of the backlight layer 102. The protective layer 104 is disposed on the side of the liquid crystal screen body 103 away from the backlight layer 102. The liquid crystal screen driving base layer 101 and the backlight layer 102 are integrated and combined using the same module, and the assembly complexity is reduced by pre-connecting the ribbon cable. The protective layer 104 adopts an anti-reflective coating, such as AR coating, to reduce the ambient light reflectivity. The integrated design of the liquid crystal screen driving base layer 101 and the backlight layer 102 not only simplifies the assembly process and improves production efficiency, but also makes the structure of the entire liquid crystal display component 1 more compact, effectively reducing space occupation. At the same time, the application of pre-connecting ribbon cable further reduces the technical difficulty in the assembly process, reduces the failure rate caused by improper ribbon cable connection, and improves the overall reliability of the product.

[0021] like Figures 1 to 4 As shown, the protective film component 2 includes a base film layer 201, a diffuser layer 202, and a prism sheet layer 203. The top surface of the base film layer 201 is provided with the diffuser layer 202, and the top surface of the diffuser layer 202 is coated with the prism sheet layer 203. The protective frame 3 is made of glass fiber reinforced nylon, and the gap between the protective frame 3 and the liquid crystal display component 1 is filled and bonded with UV-cured protective adhesive. The outer surface of the heat sink 4 is coated with a heat dissipation coating 7, and support seats 8 are fixedly connected to the four opposite corners of the heat sink 4. The heat sink 4 is made of thermally conductive silicone grease, and the heat dissipation coating 7 is made of conductive silver paste. Through the multi-layer structure design of the protective film component 2, the base film layer 201 provides a stable foundation support for the whole, ensuring that the upper structure can be firmly attached. The diffuser layer 202 uses its special microstructure to scatter light, expand the light distribution range, and improve the overall brightness of the liquid crystal display module. The prism sheet layer 203 uses a prism structure to precisely guide and focus light, further enhancing the contrast and color of the liquid crystal display module.

[0022] In summary, as Figures 1 to 4 As shown, when using this simplified cable connection LCM LCD display module, first install the LCM LCD display module to the corresponding position of the required device. Since the FPC interface cable 5 adopts a standardized interface structure, it can be directly and quickly plugged into the corresponding interface on the device to ensure a stable connection and normal signal transmission. During operation, the liquid crystal display component 1's liquid crystal screen driving base layer 101 and backlight layer 102 work together to provide stable and uniform backlight for the liquid crystal screen body 103, ensuring a clear and bright display. Simultaneously, the anti-reflective coating of the protective layer 104 effectively reduces ambient light reflection, ensuring users can clearly see the screen content even in strong light conditions without glare affecting their visual experience. The base film layer 201, diffuser layer 202, and prism sheet layer 203 in the protective film component 2 work together to further optimize light distribution and focusing, significantly improving the brightness and contrast of the displayed image, resulting in more vibrant and saturated colors. As the equipment continues to operate, the liquid crystal display component 1 will generate a certain amount of heat. At this time, the heat sink 4 begins to play its role. Its thermal grease material can quickly conduct heat from the liquid crystal display component 1 to the surface of the heat sink 4. The conductive silver paste material used in the heat dissipation coating 7 further accelerates the heat dissipation, ensuring that the liquid crystal display component 1 is always kept within a suitable operating temperature range. At the same time, the support seats 8 at the four opposite corners of the heat sink 4 not only provide stable support for the heat sink, but also play a role in static electricity discharge to a certain extent, preventing static electricity from damaging the liquid crystal display component. Throughout the entire usage process, this LCM LCD module, with its simplified cable connection, optimized display effect, and reliable protection and heat dissipation design, provides users with a stable, efficient, and high-quality display experience, meeting the stringent requirements of LCD modules in various application scenarios.
