Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to a borderless display module and a mobile terminal. Background Technology

[0002] With the continuous advancement of technology, display technology is playing an increasingly important role in the field of electronic devices, especially borderless display products, which have become a mainstream market trend. Consumers have increasingly higher demands for the appearance and display effects of display products, and extreme cost-effectiveness has become one of the key factors in market competition. However, existing borderless display module structures still have many shortcomings in meeting market demands.

[0003] Currently, there are two main solutions for borderless display modules on the market, but both have some significant limitations: One method uses a plastic frame to support the LCD panel and enclose the optical cavity. While this meets the structural requirements of the display module to some extent, the mold cost of the plastic frame is high, directly increasing material costs and thus raising the overall manufacturing cost of the product. The other method uses an "F" folded edge structure with a metal backplate, combined with silicone strips and black adhesive to assemble the display module. Although this reduces material usage to some extent, the process is more complex, requiring additional silicone strip and black adhesive application steps, which not only increases production costs but also extends the production cycle.

[0004] Therefore, how to solve the problem of high production cost of existing borderless display modules is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a borderless display module with a simple structure and low production cost.

[0006] Another objective of this invention is to provide a mobile terminal that includes the aforementioned borderless display module, with low production costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A borderless display module includes: a back plate, the back plate having a flange structure for supporting a liquid crystal panel, the flange structure including a folded edge for supporting the liquid crystal panel, the edge of the folded edge away from the back plate having a folded edge, the folded edge and the flange being transitioned by a rounded corner structure, and the flange and the folded edge being arranged parallel to each other, two flange structures overlapping each other at the corner of the back plate, the folded edge of one flange structure overlapping the flange of the other flange structure, so that a closed optical cavity is formed between the back plate, the liquid crystal panel and the flange structure.

[0009] Preferably, the outer surface of the flange is provided with a waterproof coating and an antistatic coating.

[0010] Preferably, the back panel and the flange structure are integrally formed.

[0011] Preferably, a buffer pad is provided between the folded edge and the LCD panel, and the buffer pad is bonded to the folded edge and the LCD panel.

[0012] Preferably, the back plate has a receiving cavity for carrying optical components.

[0013] Preferably, the outer edge of the flange is spaced apart from the extreme position of the outer edge of the optical component.

[0014] Preferably, the cavity is also provided with a waterproof coating and an antistatic coating.

[0015] Preferably, the back plate is made of metal.

[0016] A mobile terminal, comprising the borderless display module described in any of the preceding claims.

[0017] The frameless display module provided by this utility model includes a back plate with a flange structure for supporting the LCD panel. The flange structure is directly integrated into the back plate, providing a stable support for the LCD panel. The flange structure includes a folded edge for supporting the LCD panel. The edge of the folded edge away from the back plate has a folded flange. The folded edge and the flange are transitioned by a rounded corner structure, and the flange and the folded edge are arranged parallel to each other. The cooperative design of the folded edge and the flange makes the flange structure have higher strength and stability when supporting the LCD panel. It can effectively disperse and withstand external pressure, reduce structural deformation or damage caused by local stress, and thus significantly improve overall stability. The rounded corner structure transition design avoids direct contact between sharp edges and optical components, thereby reducing the risk of scratching optical components during assembly and use. Two flange structures overlap at the corners of the back plate, with the folded edge of one flange structure overlapping the flange of the other flange structure, so that a closed optical cavity is formed between the back plate, the LCD panel and the flange structure, effectively preventing light from leaking out from the inside of the cavity.

[0018] Compared to the solution of using a plastic frame to support the LCD panel, the frameless display module designed in the above manner does not require an additional plastic frame mold. It directly utilizes the flange structure of the back plate to achieve the support and sealing functions, thereby significantly reducing mold costs. The reduction in mold costs is directly reflected in material costs, effectively controlling the overall manufacturing cost of the product. Compared to the solution of using a metal back plate "F" folded edge structure with silicone strips and black glue, the flange structure design of this application is simpler, eliminating the need for additional silicone strips and black glue application processes. This not only reduces labor and material costs in the production process but also shortens the production cycle, improves production efficiency, and further reduces production costs.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] It should be noted that the directional terms such as "inner" and "outer" in the following text are defined based on the accompanying drawings in the instruction manual.

[0033] The core of this invention is to provide a borderless display module with a simple structure and low production cost. Another core aspect of this invention is to provide a mobile terminal including the aforementioned borderless display module, which also has low production cost.

[0034] Please refer to Figure 1 A borderless display module includes a back panel 1.

[0035] Specifically, the back panel 1 is provided with a flange structure 3 for supporting the LCD panel 2. The flange structure 3 is directly integrated into the back panel 1, providing a stable support for the LCD panel 2. The flange structure 3 includes a folded edge 31 for supporting the LCD panel 2. The inner edge of the folded edge 31 away from the back panel has a folded flange 32. The folded edge 31 and the flange 32 are transitioned by a rounded corner structure 33, and the flange 32 is arranged parallel to the folded edge 31. The cooperative design of the folded edge 31 and the flange 32 makes the flange structure 3 have higher strength and stability when supporting the LCD panel 2, and can effectively distribute and bear the load. Under external pressure, the structure is less likely to be deformed or damaged due to local stress, thus significantly improving the overall stability. The design of the rounded corner structure 33 avoids direct contact between the sharp edges and the optical components 5, thereby reducing the risk of scratching the optical components 5 during assembly and use. Two flange structures 3 overlap at the corner of the back plate 1. The folded edge 31 of one flange structure 3 overlaps the folded edge 32 of the other flange structure 3, so that a closed optical cavity is formed between the back plate 1, the liquid crystal panel 2 and the flange structure 3, effectively preventing light from leaking out from the inside of the cavity.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4 At the corner of the back panel 1, two flange structures 3 overlap each other. The folded edge 31-a of one flange structure 3 overlaps the folded edge 32-b of the other flange structure 3, so that the gap between the folded edge 31-a and the folded edge 31-b is filled by the folded edge 32-b, and the gap between the folded edge 32-a and the folded edge 32-b is filled by the folded edge 31-a, thereby ensuring that no light leaks at the corner of the back panel 1.

[0037] The integration of the flange structure 3 with the back plate 1, along with the parallel arrangement and rounded corner transition of the folded edge 31 and flange 32, makes the entire display module structure more stable. The overlapping design of the flange structures 3 at the corners of the back plate 1 further enhances the overall structural integrity, ensuring the sealing and stability of the optical cavity and preventing external impurities such as dust and liquids from entering the optical cavity, thereby extending the lifespan of the display module. The sealed optical cavity effectively prevents light scattering and interference, improving the optical performance of the display module, including contrast, color reproduction, and brightness, ensuring the clarity and color accuracy of the displayed image, and enhancing the user's visual experience.

[0038] Compared to the scheme of using a plastic frame to support the LCD panel 2, the frameless display module designed in the above manner does not require an additional plastic frame mold. It directly utilizes the flange structure 3 of the back plate 1 to achieve the support and sealing functions, thereby significantly reducing mold costs. The reduction in mold costs is directly reflected in material costs, which effectively controls the overall manufacturing cost of the product. Compared to the scheme of using a metal back plate 1 "F" folded edge 31 structure with silicone strips and black glue, the flange structure 3 of this application is simpler in design and does not require additional silicone strips and black glue processes. This not only reduces labor and material costs in the production process, but also shortens the production cycle, improves production efficiency, and further reduces production costs.

[0039] In the above embodiments, the outer surface of the flange 32 is provided with a waterproof coating and an antistatic coating.

[0040] It should be noted that the addition of a waterproof coating allows the display module to better adapt to humid or high-humidity environments, further expanding the product's application scenarios and improving its reliability and durability. The anti-static coating effectively reduces the accumulation of static electricity, preventing damage or performance degradation of the optical components 5 due to electrostatic discharge, significantly improving the display module's anti-static capability and reducing display abnormalities or malfunctions caused by electrostatic interference. The anti-static coating reduces the impact of static electricity on the optical components 5, ensuring stable operation of the display module in various environments and improving the overall product performance and user experience.

[0041] Furthermore, the combined effect of the waterproof and antistatic coatings reduces interference from the external environment on the optical component 5, ensuring stable light propagation within the optical cavity and further optimizing the optical performance of the display module, including contrast, color reproduction, and brightness. By reducing the impact of moisture and static electricity on the optical component 5, the waterproof and antistatic coatings help extend its lifespan and reduce maintenance costs. In addition, the use of waterproof and antistatic coatings does not negatively affect the appearance of the flange structure 3; on the contrary, it maintains the cleanliness and smoothness of the flange structure 3 surface, further enhancing the product's aesthetics.

[0042] In the above case, the back plate 1 and the flange structure 3 are integrally formed.

[0043] Understandably, the integrated design of the back panel 1 and the flanged structure 3 makes the entire display module more stable. It not only effectively supports the LCD panel 2 but also resists external impacts to a certain extent, reducing the risk of damage from collisions or drops, thus improving the durability and reliability of the display module. Furthermore, it simplifies and speeds up the assembly process. The elimination of additional frames or silicone strips reduces assembly steps and time, improving production efficiency. The reduced complexity of processes and the use of additional materials shortens the production cycle.

[0044] Furthermore, a buffer pad 4 is provided between the folded edge 31 and the LCD panel 2, and the buffer pad 4 is bonded to the folded edge 31 and the LCD panel 2.

[0045] It should be noted that the buffer pad 4 effectively absorbs and disperses external impact forces, reducing the risk of damage to the LCD panel 2 caused by vibration or collision, improving the impact resistance of the LCD panel 2, and extending its service life. The adhesive design of the buffer pad 4 with the folded edge 31 and the LCD panel 2 ensures a tight fit between the various parts, enhancing the overall structural stability of the display module, ensuring reliability in long-term use, and reducing manual operations and complex procedures during assembly. For example, it eliminates the need for additional fixing parts or complex installation steps, improving assembly efficiency, shortening the production cycle, and further reducing production costs.

[0046] In the above embodiment, the back plate 1 has a receiving cavity for carrying the optical component 5.

[0047] Based on the above embodiment, the outer edge of the flange 32 and the outer edge of the optical component 5 are spaced apart at their extreme positions.

[0048] It should be noted that the flange 32 completely covers the optical component 5, and the distance L between the outer edge of the optical component 5 and the outer edge of the flange 32 is greater than the limit displacement of the optical component 5 during assembly and transportation. This ensures that the flange 32 and the optical component 5 will not be scratched due to displacement, allowing the flange 32 to make contact with the optical component 5 without sharp corners. This eliminates the need for additional soft rubber strips for isolation, reducing production errors caused by inaccurate installation of the soft rubber strips, improving product quality and consistency, reducing material costs, and further lowering production costs. The L value being greater than the limit displacement of the optical component 5 during assembly and transportation ensures that the optical component 5 remains stable under various conditions, reducing the risk of structural loosening or damage due to displacement, and further enhancing the structural stability of the display module.

[0049] In the above embodiments, the cavity is further provided with a waterproof coating and an antistatic coating.

[0050] Understandably, the waterproof coating effectively prevents moisture and liquids from entering the cavity, protecting the optical components 5 from humid environments, improving the display module's waterproof performance, and reducing the risk of short circuits, corrosion, and optical performance degradation caused by moisture intrusion. Furthermore, the waterproof coating allows the display module to better adapt to humid or high-humidity environments, such as bathrooms, kitchens, or outdoor use, further expanding the product's application scenarios and improving its reliability and durability. The antistatic coating effectively reduces the accumulation of static electricity, preventing damage or performance degradation of the optical components 5 due to electrostatic discharge, improving the display module's antistatic capabilities, reducing display abnormalities or malfunctions caused by electrostatic interference, minimizing the impact of static electricity on the optical components 5, ensuring stable operation of the display module in various environments, and improving the overall product performance and user experience.

[0051] The waterproof and antistatic coatings work together to reduce interference from the external environment on the optical component 5, ensuring stable light propagation within the optical cavity and further optimizing the optical performance of the display module, including contrast, color reproduction, and brightness. By reducing the impact of moisture and static electricity on the optical component 5, the waterproof and antistatic coatings help extend its lifespan and reduce product maintenance costs.

[0052] In the above case, the back plate 1 is a metal part.

[0053] Understandably, the metal backplate 1 possesses high mechanical strength and rigidity, effectively supporting the LCD panel 2 and optical components 5, reducing structural deformation or damage caused by external impacts or vibrations, and significantly improving the overall structural stability of the display module. The uniformity and consistency of the metal material allow the backplate 1 to distribute stress more evenly, reducing localized stress concentration and further improving the structure's durability and reliability. Metal materials typically have good thermal conductivity, effectively and quickly conducting the heat generated by the optical components 5 and LCD panel 2 to the backplate 1, and then dissipating it to the external environment, significantly improving heat dissipation efficiency and reducing the operating temperature of the optical components 5. The metal backplate 1 effectively shields against electromagnetic interference, reducing the impact of external electromagnetic fields on the internal circuitry of the display module and the optical components 5, while also reducing interference from electromagnetic fields generated within the display module to external devices, improving the product's electromagnetic compatibility. Good electromagnetic shielding performance ensures the purity and integrity of signal transmission, reducing display abnormalities or performance degradation caused by electromagnetic interference, and further optimizing the display module's performance.

[0054] In summary, the borderless display module provided by this utility model, through its unique flanged structure 3 design, achieves a borderless effect, significantly increasing the screen-to-body ratio and providing users with a more immersive visual experience. This meets the demands of modern electronic devices for high screen-to-body ratios and is suitable for various application scenarios with high display performance requirements. The overlapping flanged structures 3 at the corners of the back panel 1 enhance the overall structural integrity, ensuring the sealing and stability of the optical cavity and preventing dust, liquids, and other external impurities from entering the optical cavity, thereby extending the lifespan of the display module. The closed optical cavity formed by the flanged structure 3 effectively prevents light scattering and interference, improving the optical performance of the display module, ensuring the clarity and color accuracy of the displayed image, and enhancing the user's visual experience. Compared to existing technologies, the flanged structure 3 design of this application is simpler, uses fewer materials, and is less expensive.

[0055] In addition to the borderless display modules disclosed in the above embodiments, this utility model also provides a mobile terminal including the above-mentioned borderless display module.
