[0063] It should be understood that when an element is referred to as being “disposed” on another element, it can mean that the element is directly located on the other element, or that an intervening element is present, connecting the element to the other element. Conversely, when an element is referred to as being “directly disposed on” or “directly disposed to” another element, it should be understood that the absence of intervening elements is explicitly defined.

[0064] In addition, the terms "first", "second", and "third" are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part, and do not necessarily indicate their order. In addition, relative terms such as "lower" and "upper", "parallel" and "perpendicular" may be used in this article to describe the relationship between one element and another element. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figure. For example, if a device in a figure is turned over, the element described as being on the "lower" side of the other elements will be oriented on the "upper" side of the other elements. "Lower" and "upper", "parallel" and "perpendicular" only indicate relative orientation relationships, not absolute orientation relationships.

[0065] Figure 1 is a perspective view of a first embodiment of a display device, Figure 2 The exploded view of the first embodiment of the display device is shown in FIG. Figure 3 for Figure 1 Section II of the cross section, Figure 4 for Figure 1 The cross-sectional view of section II-II, and Figure 5 for Figure 1 The cross-sectional view of the III-III plane. Figures 1 to 2 As shown, in one embodiment, the display device 1 includes a backplate structure 10, first frames 20A and 20B, a backlight module 30, a panel module 40, and a second frame 50. The backplate structure 10 includes a backplate 11, and a first sidewall 13, a second sidewall 15, and a third sidewall 17 extending perpendicularly from three sides of the backplate 11. The first sidewall 13, the second sidewall 15, and the third sidewall 17 are higher than the height of the backplate 11. In other words, the backplate structure 10 has the backplate 11 as the bottom surface and is surrounded on three sides by the first sidewall 13, the second sidewall 15, and the third sidewall 17.

[0066] The first frame 20A and the other two first frames 20B have different directions. The two first frames 20B are respectively connected to the two ends of the first frame 20A to form a "ㄇ"-shaped structure surrounded by three sides. The first frames 20A and 20B have the same cross-sectional structure, and only slightly differ in the length and end point structure. Figure 3 and Figure 4As shown in the II and II-II cross sections, the first frames 20A and 20B include a first support block 21, a second support block 23, a third support block 25, and a fourth support block 27. The first support block 21 and the second support block 23 are approximately parallel. Here, "approximately parallel" means that they appear parallel to the naked eye, but a slight angular deviation is allowed. A first accommodation space S1 is formed between the first support block 21 and the second support block 23. The third support block 25 is approximately perpendicular to the first support block 21 and the second support block 23, and the third support block 25 connects one end of the first support block 21 and the second support block 23. The fourth support block 27 extends from the second support block 23 and is approximately parallel to the third support block 25. A second accommodation space S2 is formed between the third support block 25 and the fourth support block 27. The first side wall 13, the second side wall 15, and the third side wall 17 are respectively mounted in the second accommodation space S2 of the first frames 20A and 20B.

[0067] The three edges of the backlight module 30 are respectively positioned in the third accommodation space S3 between the back panel 11 and each second support block 23, and are restrained by the fourth support block 27. The three edges of the panel module 40 are respectively positioned in the first accommodation space S1 of the first frames 20A and 20B. The ends of the second frame 50 are connected to the two first frames 20B.

[0068] like Figure 5 As shown, the cross-sectional structure of the second frame 50 includes a first abutting block 51, a second abutting block 53, a third abutting block 55, a fourth abutting block 57 and a fifth abutting block 59. The fifth abutting block 59 connects the first abutting block 51, the second abutting block 53, the third abutting block 55 and the fourth abutting block 57 which are substantially parallel. A fourth accommodating space S4 is formed between the first abutting block 51 and the second abutting block 53, and a fifth accommodating space S5 is formed between the third abutting block 55 and the fourth abutting block 57. The edge of the other side of the panel module 40 is clamped in the fourth accommodating space S4, and an edge of the back plate 11 is clamped in the fifth accommodating space S5. The edges of the other side of the backlight module 30 are respectively arranged in the sixth accommodating space S6 between the back plate 11 and the second abutting block 53.

[0069] In one embodiment, the lengths of the third abutting block 55 and the fourth abutting block 57 are smaller than the lengths of the first abutting block 51 and the second abutting block 53. However, this is merely an example and not a limitation, and can actually be adjusted according to the lengths of the back plate 11 and the panel module 40.

[0070] The display device 1 is assembled by first assembling the first frames 20A and 20B and then snapping them together with the back panel structure 10 . The backlight module 30 and the panel module 40 are then placed. Finally, the second frame 50 is snapped together with the panel module 40 and the first frame 20B to complete the assembly of the entire display device 1 .

[0071] The first frame 20A, 20B and the second frame 50 are extruded frames, which can replace conventional support frames, assembled frames, or upper frames, and are usually made of aluminum or aluminum alloy. Therefore, the extrusion or bending method can be used to form the frames without molds, thereby saving costs. Alternatively, the frames can be cast in advance, cut to a specified length, and then shipped quickly.

[0072] Further referring to Figure 1 and Figure 2 In an embodiment, the second frame 50 includes at least one slot 52, through which the flexible board 45 can be introduced to electrically connect and control the backlight module 30 and the panel module 40. The above is only an example and is not intended to be limiting. The flexible board 45 can also be replaced by a wire.

[0073] Further referring to Figures 1 to 5 In an embodiment, the first frame 20A includes a first clamping portion 22 at each end, the first frame 20B includes a second clamping portion 24 at each end, the shape of the first clamping portion 22 corresponds to the shape of the second clamping portion 24, and the first clamping portion 22 is a groove and the second clamping portion 24 is a protrusion, but the present disclosure is not limited thereto. When the first frame 20A and the first frame 20B are assembled, the first clamping portion 22 and the second clamping portion 24 are clamped and fixed. In more detail, the first clamping portion 22 or the second clamping portion 24 is formed on the first support block 21. In addition, the second frame 50 includes a third clamping portion 54 at each end, the third clamping portion 54 is clamped and fixed with the second clamping portion 24, the shape of the third clamping portion 54 can be the same as that of the first clamping portion 22, and the third clamping portion 54 is preferably located on the first abutting block 51.

[0074] Figure 6 For Figure 1 an embodiment cross-sectional view of the IV-IV cross section. As shown in Figure 6 In an embodiment, when the first frame 20B and the second frame 50 are assembled, in addition to the third clamping portion 54 being clamped and fixed with the second clamping portion 24, one end of the second abutting block 53 contacts one end of the second support block 23 of the first frame 20B, thereby achieving the effect of contact limiting. Further, the back plate 11 is located above the fourth abutting block 57 after assembly, and a portion of the back plate 11 contacts the fourth abutting block 57.

[0075] Figure 7 For Figure 1 another embodiment cross-sectional view of the IV-IV cross section. As shown in Figure 7As shown, in another embodiment, when the first frame 20B and the second frame 50 are assembled, a portion of the second abutment block 53 rests on the second support block 23 of the first frame 20B. This achieves the effect of overlapping and limiting the position. The above is merely an example and not intended to be limiting. The positions of the second abutment block 53 and the second support block 23 can also be reversed. In practice, the positions can be adjusted based on the weight and shape of the backlight module 30 and the panel module 40 to achieve a more stable effect.

[0076] Figure 8 This is a perspective view of the second embodiment of the display device. Figure 1 and Figure 2 The difference from the first embodiment is that Figure 8 As shown, in the second embodiment, the first frames 20A and 20B respectively comprise a first engaging portion 202 and a second engaging portion 204 at their ends. The first engaging portion 202 and the second engaging portion 204 are engaged and fixed. In other words, in the diagram, the first engaging portion 202 and the second engaging portion 204 are formed as a concave and convex structure. The first frames 20A and 20B are assembled in a specific orientation.

[0077] Correspondingly, the second frame 50 includes a third engaging portion 502 and a fourth engaging portion 504 at each end. The third engaging portion 502 is secured to the first engaging portion 202, and the fourth engaging portion 504 is secured to the second engaging portion 204. This allows for a pre-defined assembly sequence and orientation, while also achieving foolproof functionality. Furthermore, the first frames 20A and 20B can also be prefabricated in the same manner, enabling rapid assembly and shipment.

[0078] In summary, by directly forming the outer frame with the backplate structure 10, the first frames 20A, 20B, and second frame 50 can be formed through extrusion or bending, eliminating the need for molds. Alternatively, they can be pre-cast and then cut to length after specifications are determined. This achieves the advantages of simple assembly, cost savings, and fast delivery. Furthermore, customization is possible to meet specific specifications.

[0079] Although the technical contents of the present invention have been disclosed above in terms of preferred embodiments, they are not intended to limit the present invention. Any slight changes and modifications made by anyone skilled in the art without departing from the spirit of the present invention should be included in the scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the appended claims.
