[0026] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] This utility model provides a liquid crystal display screen that prevents the upper iron frame from swaying outwards. It includes a backlight frame, a backlight module, a display module, and an upper iron frame. The backlight frame includes a square base plate and side walls extending upwards from the edge of the base plate.

The upper iron frame includes a top plate and a baffle extending downwards from the edge of the top plate. The top plate is disposed above the display module and the side walls, and the baffle is disposed between the side walls and the limiting walls.

[0028] Since the bottom of both side walls along the length direction extends outward and then upward with multiple limiting walls, the baffle of the upper iron frame is set between the side wall and the limiting wall. After assembly, the limiting wall of the backlight frame can hold against the baffle of the upper iron frame. In this way, the upper iron frame will not be outward "eight" after the module is assembled. The upper iron frame fastener and the backlight frame can fit tightly together, and the upper iron frame will not loosen and detach under the vibration of application and transportation.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1, please refer to Figures 1 to 4This utility model provides a liquid crystal display screen that prevents the upper iron frame from swaying outwards. It includes a backlight frame 1, a backlight module 2, a display module 3, and an upper iron frame 4. The backlight frame 1 includes a square base plate 11 and side walls 12 extending upwards from the edge of the base plate 11. The bottom of the two side walls 12 in the length direction extends outwards and then upwards to have multiple limiting walls 13. The backlight module 2 is disposed inside the backlight frame 1. The display module 3 is disposed above the backlight frame 1 and within the space enclosed by the side walls 12. The upper iron frame 4 includes a top plate 41 and a baffle wall 42 extending downwards from the edge of the top plate 41. The top plate 41 is disposed above the display module 3 and the side walls 12, and the baffle wall 42 is disposed between the side walls 12 and the limiting walls 13. Since the bottom of both side walls 12 in the length direction extends outward and then upward with multiple limiting walls 13, the baffle 42 of the upper iron frame 4 is set between the side wall 12 and the limiting wall 13. After assembly, the limiting wall 13 of the backlight frame 1 can hold against the baffle 42 of the upper iron frame 4. In this way, the upper iron frame 4 will not be outward "eight" after the module is assembled. The upper iron frame 4 and the backlight frame 1 can fit tightly together. Under the vibration state of application and transportation, the upper iron frame 4 is prevented from loosening and falling off.

[0031] Furthermore, the thickness of the limiting wall 13 is 0.8mm, the gap between the limiting wall 13 and the baffle 42 is 0.08mm, the height of the limiting wall 13 is 2mm-3mm, the width of the limiting wall 13 is 3mm, and there are four limiting walls 13. Two limiting walls 13 are respectively provided on the side walls 12 in the two length directions to prevent the upper iron frame 4 from deforming outwards, thereby solving the risk of the upper iron frame 4 detaching.

[0032] Example 2, please refer to Figures 1 to 4 As a further optimization of Embodiment 1, in this embodiment, the upper iron frame 4 has a buckle hole 43 on the baffle 42, and the backlight frame 1 has a buckle 14 on the side wall 12 corresponding to the position of the buckle hole 43. After assembly, the buckle 14 is fastened to the buckle hole 43, thereby realizing the fixation between the upper iron frame 4 and the backlight frame 1.

[0033] Furthermore, the end of the baffle 42 is provided with a clearance 44 to allow the limiting wall 13 to pass through, thereby allowing the limiting wall 13 to pass through easily and avoiding increasing the product thickness.

[0034] Furthermore, the backlight module 2 extends outward with a backlight FPC 5, and the display module 3 extends outward with a display FPC 6. The backlight FPC 5 is bound to the display FPC 6, thereby enabling one FPC to be separated into two FPC segments, which are respectively connected to the backlight module 2 and the display module 3.
