Description

Technical Field

[0001] The present invention relates to the field of display modules, and in particular to a double-layer F-bend backplane for TV and MNT products. Background Art

[0002] In the field of mainstream TV metal frameless product manufacturing, the back panel integrated molding process is generally adopted, in which the display screen is attached to the single-layer F-shaped bending edge formed by the back panel stamping through a foam strip (such as Figure 1 As industry competition intensifies, the thickness of backplane materials continues to decrease, significantly degrading the overall structural strength of the traditional single-layer F-shaped edge. This single-layer bent structure suffers from inherent flaws due to insufficient material thickness: first, the supporting rigidity of the glass display attachment surface is weak, making it prone to collapse and deformation during assembly and handling; second, the foam adhesive attachment area lacks torsional resistance, prone to localized deformation under stress. These structural flaws result in light leakage due to the uneven attachment surface after module screen assembly, while also reducing the overall torsional rigidity of the backplane, directly impacting the stability of the product in vibration and drop tests, and becoming a key technical bottleneck restricting the structural reliability of ultra-thin TVs. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-layer F-bent back panel for TV and MNT products to solve the technical problems of poor rigidity and deformation caused by insufficient material thickness in existing single-layer bent structures.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: The double-layer F-bent back panel of TV and MNT products includes a back panel, the edge of which is a bent portion, the bent portion is a double-layer structure formed by continuous bending, and the bent portion forms an F-shaped groove on the top side and the left and right sides of the back panel.

[0005] Preferably, the bending portion includes flange one which is the first bending portion of the back panel edge, another bending portion formed after flange one is bent is flange two, another bending portion formed after flange two is bent is flange three, and another bending portion formed after flange three is bent is flange four.

[0006] Preferably, flange 1 and flange 2 constitute the first section of the double-layer structure, and flange 3 and flange 4 constitute the second section of the double-layer structure.

[0007] Preferably, the first double-layer structure and the second double-layer structure form an angle.

[0008] Preferably, the second section of the double-layer structure forms a sandwich to the main body of the back plate.

[0009] Preferably, the opposite side of the interlayer is a support area for mounting a display screen.

[0010] The beneficial effects of the present invention are: 1. The bending portion of the present invention adopts an integral double-layer structure formed by a continuous bending process. This double-layer design significantly enhances the structural strength, rigidity and deformation resistance of the back panel edge, improves the overall mechanical stability of the product, can better protect internal components, and helps maintain the product shape.

[0011] 2. The F-shaped groove structure is formed by continuously bending the edge of the back panel body in one step. This integrated design reduces the number of parts, simplifies the manufacturing process, helps reduce costs and improve production consistency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0015] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0016] Example 1: In this example, a double-layer F-bend back sheet for TV and MNT products is proposed. Figure 2-Figure 5The double-layer F-bent back panel of the TV and MNT products includes a back panel 1. The edge of the back panel 1 is formed into a bending portion through a continuous bending process. The bending portion is an integral double-layer structure formed by continuous bending, and a groove-shaped structure with an F-shaped cross-section is also formed on the sky side and the left and right sides of the back panel 1. Specifically, the bending portion includes a flange 2 starting from the edge of the back panel 1. The end of the flange 2 is bent to form a flange 3. The end of the flange 23 continues to be bent to extend into a flange 3 4. The end of the flange 3 4 is finally bent to form a flange 4 5. Among them, the flange 1 2 and the flange 2 3 are tightly stacked to form the first section of the double-layer structure, and the flange 3 4 and the flange 4 5 are tightly stacked to form the second section of the double-layer structure. There is a 90° angle between the first section and the second section. Specifically, the 90° angle between the first section and the second section is that the spatial angle α between the flange 3 4 and the flange 2 3 is constructed to be equal to 90°. Please refer to Figure 3-Figure 5 A sandwich space is formed between the bottom of the second section of the double-layer structure and the main body of the back panel 1. This space can be used for cable routing or as an installation area for a diffusion plate and a diffusion membrane. At the same time, a step portion is formed between the outer edges of the second section of the double-layer structure and the first section of the double-layer structure. The step portion provides a precise positioning surface for installing the display screen.

[0017] Example 2: Figure 6 The double-layer F-bend backplane of the TV / MNT product shown includes a backplane 1, whose edges are continuously bent to form an integral double-layered bent portion. This bent portion forms an F-shaped groove structure on the top and left and right sides of the backplane 1. Specifically, the bent portion begins at flange 1 (2) on the edge of the backplane 1, bends to form flange 2 (3), which then bends further to form flange 3 (4), which finally bends to form flange 4 (5). The key structural feature that distinguishes this embodiment from Example 1 is that the spatial angle α between flange 3 (4) and flange 2 (3) is configured to be less than 90° and greater than or equal to 88° (i.e., 88° ≥ α > 90°). In the above description, flange 1 2 and flange 2 3 are tightly stacked to form the first section of the double-layer structure, and flange 3 4 and flange 4 5 are tightly stacked to form the second section of the double-layer structure. A sandwich space is formed between the second section of the double-layer structure and the main body of the back panel 1. This space is used for cable routing or as an installation area for a diffuser plate and a diffuser film, and its opposite side is the support area of the display screen.

[0018] Example 3: Figure 7The double-layer F-bend backplane of the TV / MNT product shown includes a backplane 1, whose edges are continuously bent to form an integral double-layered bent portion. This bent portion forms an F-shaped groove structure on the top and left and right sides of the backplane 1. Specifically, the bent portion begins at flange 1 (2) on the edge of the backplane 1, bends to form flange 2 (3), which then bends further to form flange 3 (4), which finally bends to form flange 4 (5). The key structural feature that distinguishes this embodiment from Example 1 is that the spatial angle α between flange 3 (4) and flange 2 (3) is configured to be greater than 90° and less than or equal to 92° (i.e., 92° ≥ α > 90°). In the above description, flange 1 2 and flange 2 3 are tightly stacked to form the first section of the double-layer structure, and flange 3 4 and flange 4 5 are tightly stacked to form the second section of the double-layer structure. A sandwich space is formed between the second section of the double-layer structure and the main body of the back panel 1. This space is used for cable routing or as an installation area for a diffuser plate and a diffuser film, and its opposite side is the support area of the display screen.
