Description

Technical Field

[0001] The present invention relates to an assembly frame, a backlight module and a display device, and in particular to an assembly frame with an assembly margin, a backlight module and a display device having the assembly frame. Background Art

[0002] Existing display devices, especially liquid crystal displays, generally include a display panel and a backlight module, and are provided with a frame assembly to fix the backlight module and connect the display panel. In addition, existing displays mainly tend to be thinner and larger in design. In particular, narrow-framed displays, in addition to being aesthetically pleasing, can also increase the display area of ​​the display, and have therefore gradually become popular in the market. However, narrow-framed displays require high assembly precision, and once there is a slight error in the size of some components, this will increase the difficulty of assembly. In order to make the narrow frame more extreme and to achieve higher precision requirements after the overall assembly of the display, the assembly frame of the existing display has almost no adjustment margin. For example, the assembly frames in Chinese patent application CN101206338 or Chinese patent application CN103953874 do not have an assembly adjustment margin. Therefore, when assembling with a narrow-framed display, it is easy to cause assembly difficulties due to the dimensional errors of each component, so it is necessary to further improve it. Summary of the Invention

[0003] Therefore, in view of the shortcomings and deficiencies in the structure and use of the assembly frame of the existing display, the inventor has finally developed a present invention that can improve the existing deficiencies through continuous experiments and improvements.

[0004] The primary objective of the present invention is to provide an assembly frame having adjustment margins formed in two mutually perpendicular directions. This allows the assembly position of the assembly frame to be appropriately adjusted based on the tolerances of various components of a display device, thereby improving the convenience and efficiency of assembling the display device.

[0005] In order to achieve the above objectives, the present invention mainly provides an assembly frame, which includes:

[0006] a connecting frame having at least one first side bar and at least one second side bar, wherein the at least one first side bar extends along a first direction, and the at least one second side bar extends along a second direction, wherein the first direction and the second direction are perpendicular to each other; and

[0007] A back plate is connected to the connection frame, and an adjustment margin is provided between the back plate and the at least one first side bar along the second direction, and an adjustment margin is provided between the back plate and the at least one second side bar along the first direction.

[0008] To achieve the above-mentioned object, the present invention further provides a backlight module comprising:

[0009] the assembly frame;

[0010] a plurality of light sources, which are arranged on the bottom surface of the back plate in the assembly frame; and

[0011] At least one optical film is arranged on the connecting frame.

[0012] To achieve the above object, the present invention further provides a display device comprising:

[0013] the assembly frame;

[0014] A panel fixing frame, which is fixedly connected to the connecting frame;

[0015] A display panel assembled on the panel fixing frame; and

[0016] A plurality of light sources are arranged on the bottom surface of the back plate in the assembly frame.

[0017] By means of the above-mentioned technical means, the present invention can utilize an adjustment structure to provide adjustment margin when assembling the back panel and the connecting frame along the first direction and the second direction, thereby eliminating the assembly inconvenience caused by the tolerances of each component during production, thereby improving the efficiency and convenience of the overall assembly of the display device.

[0023] The present invention relates to an assembly frame, a backlight module and a display device. Figures 1 to 3As can be seen from the figure, the assembly frame of the present invention mainly includes a connecting frame 10 and a back plate 20. The connecting frame 10 has at least one first side strip 12 and at least one second side strip 14. At least one first side strip 12 extends along the first direction D1, and at least one second side strip 14 extends along the second direction D2, and the first direction D1 and the second direction D2 are perpendicular to each other. Preferably, the connecting frame 10 may have two mutually parallel first side strips 12 and two mutually parallel second side strips 14, thereby forming a square or rectangular connecting frame 10. In addition, the two adjacent first side strips 12 and second side strips 14 of the connecting frame 10 may overlap with each other, wherein overlapping refers to the use of complementary shapes or the use of concave and convex parts to join side by side, so that the overlapping parts of the adjacent first side strips 12 and second side strips 14 are formed with gaps G1 and G2 corresponding to the first direction D1 and the second direction D2 respectively. Please refer to Figure 4 The assembly frame of the present invention is further provided with a plurality of light sources (not shown in the figure) and at least one optical film 70 to form a backlight module. The plurality of light sources are arranged on the bottom surface of the back panel 20 in the assembly frame and are electrically connected to the outside. The optical film 70 is provided on the connecting frame 10, and the connecting frame 10 and the panel fixing frame 30 clamp the optical film 70. The optical film 70 can be a film with different optical properties such as a diffuser, a reflector, a color conversion film, a prism, a light guide film or a light guide plate, but is not limited thereto. The display device of the present invention is completed by matching the backlight module composed of the aforementioned assembly frame, the light source and the optical film with the panel fixing frame 30, and then combining the display panel 60 with the above-mentioned assembly frame.

[0024] Please refer to Figures 1 to 4The backplate 20 and the connecting frame 10 are fixedly connected to each other. An adjustment margin is provided between the backplate 20 and at least one first side bar 12 along the second direction D2, and an adjustment margin is provided between the backplate 20 and at least one second side bar 14 along the first direction D1. Preferably, the shape of the backplate 20 is square or rectangular to match the shape of the connecting frame 10. Furthermore, the backplate 20 has at least one first portion 202 and at least one second portion 204. The at least one first portion 202 corresponds to the first side bar 12 of the connecting frame 10, and the at least one second portion 204 corresponds to the second side bar 14 of the connecting frame 10. A plurality of first adjustment structures 22 arranged along the first direction D1 are provided on the at least one first portion 202, and a plurality of second adjustment structures 24 arranged along the second direction D2 are provided on the at least one second portion 204. Multiple first adjustment structures 22 and multiple second adjustment structures 24 can be provided based on bonding strength requirements to enhance the bonding strength between the backplate 20 and the connecting frame 10. In one embodiment, each first adjustment structure 22 is a long groove recessed along the second direction D2 on the periphery of the back plate 20, and each second adjustment structure 24 is a long groove recessed along the first direction D1 on the periphery of the back plate 20. In addition, coupling holes 16 are provided on the connection frame 10 at positions corresponding to each first adjustment structure 22 and each second adjustment structure 24. In this way, by passing a coupling member 40 such as a bolt through each first adjustment structure 22 and second adjustment structure 24 and then screwing it into the corresponding coupling hole 16, the connection frame 10 and the back plate frame 20 can be fixedly coupled to each other. Secondly, the first adjustment structure 22 and the second adjustment structure 24 can also be provided on the first side bar 12 and the second side bar 14 of the connection frame 10, and the coupling hole 16 can be provided on the back plate 20, so that the same effect can be achieved.

[0025] The panel fixing frame 30 is fixedly connected to the connecting frame 10 to fix the display panel 60. The panel fixing frame 30 includes a plurality of frame strips 32. The frame strip 32 has a bonding surface 321. The bonding surface 321 of the frame strip 32 is bonded to the display panel 60 by adhesive 50. The area of ​​the bonding surface 321 can be less than 2 mm, thereby obtaining a more extreme narrow-frame display device. In one embodiment, a groove can be provided on the bonding surface 321 of the frame strip 32 to accommodate the adhesive 50 to prevent the adhesive 50 from being applied to the frame strip 32 and overflowing. The adhesive 50 can be a double-sided tape with thickness and elasticity or a colloid with elasticity, such as silicone or foam glue, so that each frame strip 32 can be deflected at a specific angle relative to the display panel 60 or adjacent frame strips 32. Furthermore, each frame strip 32 of the panel fixing frame 30 is provided with at least one elongated through-hole 34, while the first and second side strips 12, 14 of the connecting frame 10 are provided with locking holes 18 at positions corresponding to the elongated through-holes 34 of the panel fixing frame 30. Thus, by passing a plurality of fixing members 42 through the elongated through-holes 34 of the panel fixing frame 30 and locking them with the corresponding locking holes 18 on the connecting frame 10, the panel fixing frame 30 and the connecting frame 10 are fixedly connected to each other. Furthermore, due to the shape of the elongated through-holes 34, the longer elongated through-holes 34 can be used in conjunction with the smaller locking holes 18 during assembly, making it easier to align each frame strip 32 with the first and second side strips 12, 14, thereby improving assembly efficiency.

[0026] Please refer to Figure 4 The connecting frame 10 has a supporting surface 102, and the frame strip 32 has a pressing portion 322. According to user needs, multiple desired optical films 70 can be placed on the supporting surface 102 of the connecting frame 10, and the pressing portion 322 of the panel fixing frame 30 can cooperate with the supporting surface 102 of the connecting frame 10 to clamp the optical films 70. In addition, by providing an adjustment margin along the second direction D2 between the back panel 20 and at least one first side strip 12, and an adjustment margin along the first direction D1 between the back panel 20 and at least one second side strip 14, the relative position between the connecting frame 10 and the back panel 20 can be adjusted, and thus the relative position of the optical film 70 and the panel fixing frame 30 can be adjusted to control the size of the gap G3 between the optical film 70 and the frame strip 32, thereby providing space for the optical film 70 to expand and contract with heat.

[0027] When assembling the display device, please refer to Figures 2 to 4 , the back panel 20 and the connecting frame 10 can be connected to each other through the coupling 40, and then the display panel 60 can be fixed to the panel fixing frame 30 through the adhesive 50. Then, the combination of the connecting frame 10 and the back panel 20 is placed in the panel fixing frame 30, and then the panel fixing frame 30 and the connecting frame 10 are fixedly connected to each other through the fixing members 42. In this way, the assembly operation of the display device can be completed by assembling the frame.

[0028] When assembling the display device, please refer to Figure 5 If there are tolerances in components during manufacturing, the first adjustment structure 22 and the second adjustment structure 24 on the back panel 20 can be used to appropriately adjust the relative position between the back panel 20 and the connecting frame 10 along the first direction D1 and / or the second direction D2, so as to provide an adjustment margin along the first direction D1 and / or the second direction D2 when the back panel 20 and the connecting frame 10 are combined, thereby overcoming the tolerance requirements during component manufacturing or assembly, and improving the assembly efficiency and convenience of the display device.

[0029] Secondly, because the frame bars 32 of the panel fixing frame 30 are connected to the display panel 60 via adhesive 50 and can be tilted outward at a specific angle, such as 20 degrees, relative to the panel, when the connection frame 10 and back panel 20 are assembled into the panel fixing frame 30, the frame bars 32 can be tilted slightly outward relative to the center of the panel 60. By leveraging the angle-adjustable properties of the adhesive 50 and the frame bars 32, the connection frame 10 and back panel 20 can be more smoothly enclosed and accommodated within the panel fixing frame 30. Thus, the present invention can be applied to larger display devices, such as televisions or monitors, thereby facilitating the assembly of large display panels.

[0030] Secondly, the adjustment margin between the connecting frame 10 and the back panel 20 can also be achieved by utilizing the gaps G1 and G2 formed at the overlapping joints between the first side bar 12 and the second side bar 14 of the connecting frame 10. By utilizing the gap G1 in the first direction D1 and the gap G2 in the second direction D2 at the overlapping joints between the first side bar 12 and the second side bar 14, the locking position between the connecting frame 10 and the back panel 20 can be adjusted to avoid the effects of component tolerances that may cause assembly difficulties. Furthermore, the angle-adjustable nature of the frame bar 32 allows for the overall assembly tolerances of the connecting frame 10 and the back panel 20 to be accommodated, thereby improving the efficiency and convenience of the overall assembly of the display device.
