The first mounting part 02 formed by the F-shaped structure is used to connect the display screen, and the second mounting part 03 formed by the F-shaped structure is used to connect the diaphragm. The first mounting part 02 can be formed directly using the top plane of the back panel, but there is a seam 01 between two adjacent first mounting parts 02, which needs to be sealed by applying adhesive to prevent light transmission. In this method, multiple first mounting parts 02 need to be set and combined with the adhesive application process. The second mounting part 03 and the first mounting part 02 need to be fitted with a protective component to protect the diaphragm, resulting in high material and labor costs.

[0004] In conclusion, how to reduce the material and labor costs of television back panels is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0036] 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.

[0037] The core of this invention is to provide a backplate structure that, by making both the first and second mounting layers a continuous plane integrally formed from the backplate body, provides reliable and effective support for the display screen and the brightness enhancement film, eliminating the need for adhesive application and film strips, thus reducing material and production costs. Another core aspect of this invention is to provide a television set incorporating the aforementioned backplate structure.

[0038] The back panel structure provided by this utility model includes a back panel body, a first mounting layer 1 and a second mounting layer 2. The first mounting layer 1 and the second mounting layer 2 are both located inside the back panel body. The specific structure of the back panel body can be set according to the matching display, visual electrical appliance, etc.

[0039] Please refer to Figure 2 , Figure 5 The first mounting layer 1 is used to support the circumference of the display screen 3. Specifically, the first mounting layer 1 is set as a continuous plane integrally formed with the back panel body to avoid light leakage from the lamp tubes inside the display screen 3 and ensure the display effect of the display screen 3.

[0040] By setting the first mounting layer 1 as a continuous plane, there is no need for splicing, no need for glue, no need for manual glue application, and no need to consider the coating effect of glue at the splicing position. The first mounting layer 1, which is simply integrally formed with the back panel body, can achieve the effect of preventing the display screen 3 from transmitting light, thereby reducing material and labor costs.

[0041] The second mounting layer 2 is located below the first mounting layer 1, and forms a support and limiting installation protective space for the brightness enhancement film 4 with the lower side of the display screen 3. The upper and lower sides here are... Figure 5 In terms of orientation, the brightness enhancement film 4 ensures the display effect of the display screen 3. The second mounting layer 2 is also a continuous plane integrally formed on the back panel body, ensuring reliable support for the brightness enhancement film 4. This is the installation of the brightness enhancement film 4. Specifically, protection means that when the brightness enhancement film 4 is installed on the second mounting layer 2, during transfer and transportation or in the event of impact, the brightness enhancement film 4 will move within this height difference range. The plane of the display screen 3 directly provides protection for the brightness enhancement film 4, effectively preventing damage to the brightness enhancement film 4. This eliminates the need for separate protective components, reducing material processing costs.

[0042] It should be noted that the aforementioned continuous plane is an uninterrupted, complete plane, consisting of only one complete plane, not two or more planes pieced together. Therefore, for the first mounting layer 1 supporting the display screen 3, no seam will be formed, effectively preventing light transmission and eliminating the need for seam adhesive application, thus improving production efficiency and reducing material costs. For the brightness enhancement film 4, it can effectively and reliably support and protect the film, ensuring the performance of the brightness enhancement film 4.

[0043] Specifically, the method of integrally molding the first mounting layer 1 and the second mounting layer 2 can be achieved by using a mold, which can improve the production efficiency of the back plate structure and ensure the strength of the back plate structure.

[0044] Alternatively, the first mounting layer 1 and the second mounting layer 2 can be integrally formed by bending, which can improve the production efficiency of the back panel structure and ensure the strength of the back panel structure.

[0045] By integrally molding the first mounting layer 1 and the second mounting layer 2 onto the back panel body, and forming an installation and protection space for supporting and limiting the brightness enhancement film 4 through the second mounting layer 2 and the display screen 3, material costs and labor costs are reduced. The structure is simple and reliable, which enhances the product competitiveness of the back panel structure.

[0046] Based on the above embodiment, the lower side of the second mounting layer 2 is a mounting chamber for mounting electronic devices, the first mounting layer 1 and the second mounting layer 2 form a stepped structure, and the second mounting layer 2 is disposed near the center of the mounting chamber relative to the first mounting layer 1.

[0047] Please refer to Figure 2 , Figure 5 The lower side of the second mounting layer 2 is a mounting chamber, which is located inside the back panel and is used to mount the supporting electronic components of the television.

[0048] The first mounting layer 1 and the second mounting layer 2 form a stepped structure, and a stepped structure is formed between the two, so that the installation of the display screen 3 and the brightness enhancement film 4 do not interfere with each other. The specific height of the steps is set according to the actual installation situation.

[0049] Furthermore, the second mounting layer 2 is positioned closer to the center of the mounting chamber than the first mounting layer 1. The continuous planar area of ​​the first mounting layer 1 is larger than that of the second mounting layer 2, which facilitates the installation of the first mounting layer 1 and the second mounting layer 2. This allows the display screen 3 on the first mounting layer 1 to directly provide protection for the brightness enhancement film 4 on the second mounting layer 2, eliminating the need for separate protective components (such as silicone strips for pressing the film), and further reducing the production cost of the back panel structure.

[0050] By placing the brightness enhancement film 4 on the second mounting layer 2, which is relatively close to the inner side of the mounting cavity, the brightness enhancement film 4 directly faces the display screen 3. The display screen 3 provides protection for the brightness enhancement film 4. If the brightness enhancement film 4 moves to contact the display screen 3 during transportation, the relatively smooth display screen 3 avoids scratching of the brightness enhancement film 4 compared to a backplate structure. Based on this staged structure, there is no need to separately install silicone strips or other protective components to protect the brightness enhancement film 4, further reducing material costs and improving production efficiency.

[0051] Based on any of the above embodiments, the first mounting layer 1 and the second mounting layer 2 are connected by a bending portion 5 to form a stepped structure, and the included angles between the first mounting layer 1 and the bending portion 5 and between the second mounting layer 2 and the bending portion 5 are both obtuse angles.

[0052] Please refer to Figure 3 , Figure 5 The bending part 5 is used to connect the first mounting layer 1 and the second mounting layer 2, so that the second mounting layer 2 is set close to the center of the mounting chamber. The bending part 5 also creates a certain height difference between the first mounting layer 1 and the second mounting layer 2. When the brightness enhancement film 4 is installed on the second mounting layer 2, it will move within this height difference range during transfer and transportation or when bumped. The plane of the display screen 3 provides protection for the brightness enhancement film 4, effectively avoiding damage to the brightness enhancement film 4.

[0053] The bent portion 5 has a certain angle. Specifically, during the integral bending process, the included angles between the bent portion 5 and the first mounting layer 1, as well as between the bent portion 5 and the second mounting layer 2, are all obtuse angles. The specific angle of this obtuse angle can be determined based on the actual processing conditions and is not limited.

[0054] Based on any of the above embodiments, the bending portion 5 is provided with a limiting portion for contacting the brightening film 4 to limit its displacement.

[0055] By providing a limiting part on the bending portion 5, the limiting part can specifically be a limiting protrusion. The brightness enhancement film 4 is disposed between the limiting protrusion and the second mounting layer 2. Through the circumferential contact between the limiting protrusion and the brightness enhancement film 4, the movement of the brightness enhancement film 4 from the second mounting layer 2 is restricted, limiting the offset and shaking of the brightness enhancement film 4 during transfer and transportation, and ensuring the reliable stability of the brightness enhancement film 4.

[0056] It should be noted that the limiting protrusion is merely a small protrusion on the bent portion 5, serving only to support and limit the brightness enhancement film 4. There is no need to set too many; for example, limiting protrusions can be set at both ends along the length of the bent portion 5 to limit the periphery of the brightness enhancement film 4. Here, the length of the bent portion 5 refers to the longer side of the bent portion 5.

[0057] It should be further explained that the material of the limiting protrusions should be selected and set based on the premise that it will not wear down the brightening film 4, and that it has a supporting and limiting effect.

[0058] Based on any of the above embodiments, the first mounting layer 1 has a U-shaped cross-section, and the second mounting layer 2 has a frame-like cross-section, such as... Figure 3 and Figure 4 As shown.

[0059] Both the frame structure and the U-shaped structure have continuous planar cross-sections, effectively preventing light leakage. There are no seams, eliminating the need for adhesive application and reducing production costs for the back panel structure. The corners of both the frame structure and the U-shaped structure are rounded, ensuring a smooth transition and preventing wear on the display screen 3 and the brightness enhancement film 4, as well as avoiding scratches to operators during manual assembly.

[0060] Based on any of the above embodiments, the first mounting layer 1, the second mounting layer 2, and the bending portion 5 are integrally bent and formed, which improves production efficiency while ensuring the overall structural strength of the back panel structure and enhances the market competitiveness of the back panel structure.

[0061] In addition to the aforementioned back panel structure, this utility model also provides a television set including the back panel structure disclosed in the above embodiments, the television set comprising:

[0062] The backplate structure is the backplate structure of any of the above embodiments;

[0063] The display screen 3 and the first mounting layer 1 of the U-shaped structure are connected by double-sided adhesive 6 to fix the display screen 3 and the back panel structure.

[0064] A brightness enhancement film 4 is disposed between the rear end of the display screen 3 and the second mounting layer 2 of the frame structure. Specifically, it is supported between the display screen 3 and the second mounting layer 2. In operation, the brightness enhancement film 4 is disposed on the second mounting layer 2. More specifically, the brightness enhancement film 4 includes a double-layer film, with a thinner upper layer and a thicker lower layer. The thicker lower layer provides reliable support for the upper layer, preventing the brightness enhancement film 4 from moving downwards and falling off the second mounting layer 2. This ensures the overall strength and reliability of the brightness enhancement film 4, guarantees the relative stability and reliability between the brightness enhancement film 4 and the second mounting layer 2, and ensures the reliable performance of the brightness enhancement film 4.

[0065] The reflective element 7 is disposed between the second mounting layer 2 and the brightness enhancement film 4, specifically between the second mounting layer 2 and the thicker lower film of the brightness enhancement film 4, and is used to reflect and concentrate the light from the TV's lamp bar to form a better visual effect.

[0066] Based on any of the above embodiments, the bent portion 5 of the back panel structure is attached to the end of the brightness enhancement film 4. In this case, if the brightness enhancement film 4 is a square structure, the bent portion 5 can be set vertically. The vertical setting means that the bent portion 5 is perpendicular to the first mounting layer 1 or the second mounting layer 2. By attaching the end of the brightness enhancement film 4 to the bent portion 5, the bottom of the brightness enhancement film 4 is supported on the second mounting layer 2, ensuring the reliable and stable installation of the brightness enhancement film 4 and ensuring the reliable working effect of the brightness enhancement film 4.

[0067] Alternatively, the bent portion 5 of the back panel structure is partially attached to the end of the brightness enhancement film 4. In this case, the bent portion 5 is inclined. When supporting the brightness enhancement film 4, only part of the inclined surface of the bent portion 5 can be attached to the brightness enhancement film 4, such as the bottom of the inclined surface. However, even if only part of the surface is attached, the reliable and stable installation effect of the brightness enhancement film 4 can still be guaranteed.

[0068] Based on any of the above embodiments, the bending portion 5 is provided with a limiting groove to restrict the movement of both ends of the brightness enhancement film 4. The limiting groove is used to restrict the movement of the brightness enhancement film 4 toward the display screen 3.

[0069] The limiting groove is essentially a groove on a certain section of the length of the bent portion 5. It is not necessary to open the limiting groove along the entire length to ensure the structural strength of the bent portion 5. For example, a limiting groove is provided at the end position of the bent portion 5 along the length direction. The limiting groove contacts the brightness enhancement film 4 to limit the offset or movement of the brightness enhancement film 4.

[0070] Based on any of the above embodiments, double-sided adhesive 6 connects the circumferential direction of the display screen 3 and the first mounting layer 1. The double-sided adhesive 6, the first mounting layer 1, and the first mounting layer 1 are bonded together to ensure reliable fixation of the display screen 3 and the first mounting layer 1.

[0071] There is a gap between the back panel body and the inner wall corresponding to the first mounting layer 1 and the display screen 3, and this gap does not require filling adhesive.

[0072] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0073] The foregoing has provided a detailed description of the back panel structure and television set provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
