Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, and more specifically, to a reverse-assembleable upper iron frame and liquid crystal display screen. Background Technology
[0002] During the assembly of the TFT module into the backlight module, it needs to be positioned by the edge of the slot in the backlight module. This structure can easily cause the TFT module to deviate to the sides, making it impossible to assemble. Even if it is successfully assembled, it is easy to fall off if it is deviated, resulting in product defects and reducing the product's competitiveness. Utility Model Content
[0003] The technical problem to be solved by this utility model is how to avoid using the edge of the slot of the backlight module for positioning, thereby preventing the TFT module from being misaligned to both sides. By first assembling the TFT module and the upper iron frame in reverse, and then assembling it with the backlight module, it is possible to avoid falling off due to misalignment, thereby increasing product yield and improving product competitiveness.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0029] 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.
[0030] This utility model provides a reversible upper iron frame, which includes a frame-shaped top plate and a plurality of side walls extending downward from the edge of the top plate. Each side wall is provided with at least one protrusion. The protrusion includes a guide plate and a positioning plate. The guide plate is connected to the side wall and extends from bottom to top and is obliquely arranged. The positioning plate is disposed at the end of the guide plate and is parallel to the side wall.
[0031] Because the upper frame has guide plates and positioning plates on its side walls, the guide plates can be used to guide the TFT module during assembly, and the positioning plates can be used to position and limit the TFT module. During assembly, the TFT module is first assembled onto the upper frame in reverse, and then the upper frame and TFT module are assembled onto the backlight module. This avoids using the edge of the slot of the backlight module for positioning, thereby preventing the TFT module from shifting to the sides and falling off due to shifting, increasing product yield and improving product competitiveness.
[0032] 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.
[0033] Example 1, please refer to Figures 1 to 3 The present invention provides a reversibly assembled upper iron frame 100, which includes a frame-shaped top plate 1 and a plurality of side walls 2 extending downward from the edge of the top plate 1. In this embodiment, each side wall 2 is provided with at least one protruding block 3. In this embodiment, each side wall 2 is provided with two protruding blocks 3. The protruding block 3 includes a guide plate 31 and a positioning plate 32. The guide plate 31 is connected to the side wall 2 and extends from bottom to top and is obliquely arranged. The positioning plate 32 is arranged at the end of the guide plate 31 and is parallel to the side wall 2. Since the upper frame 100 is provided with a guide plate 31 and a positioning plate 32 on its side wall 2, the guide plate 31 can be used to guide the TFT module 200 during assembly, and the positioning plate 32 can be used to position and limit the TFT module 200. During assembly, the TFT module 200 is first assembled onto the upper frame 100 in reverse, and then the upper frame 100 and the TFT module 200 are assembled onto the backlight module. This avoids using the edge of the slot of the backlight module for positioning, thereby preventing the TFT module 200 from shifting to both sides, thus preventing it from falling off due to shifting, increasing product yield, and improving product competitiveness.
[0034] Furthermore, the guide plate 31 has an inclination angle of 60° to ensure that the guide plate 31 provides good guidance.
[0035] Furthermore, a first foam adhesive 4 is pasted on the lower surface of the top plate 1. The thickness of the first foam adhesive 4 is 0.3mm. There are two or four strips of the first foam adhesive 4 to prevent the burrs on the edge of the upper iron frame 100 from scratching the surface of the TFT module 200.
[0036] Example 2, please refer to Figures 4 to 7 This utility model provides a liquid crystal display screen, comprising an upper frame 100 as described in any of the above claims and a TFT module 200, wherein the TFT module 200 is disposed within the area defined by the protrusion 3. The distance between the edge of the TFT module 200 and the positioning plate 32 is 0.05 mm. A backlight module is disposed below the TFT module 200, the backlight module comprising a lower frame 300 and a frame 400, the frame 400 being disposed on and fixed to the lower frame 300, and the frame 400 having a clearance portion 401 corresponding to the protrusion 3 to prevent interference between the protrusion 3 of the upper frame 100 and the frame 400. A second foam adhesive 402 is disposed on the upper surface of the frame 400, the second foam adhesive 402 preventing direct compression with the TFT module 200 and avoiding MURA defects. A buckle is disposed on the frame 400, and a corresponding slot is disposed on the side wall 2, the buckle engaging and securing with the buckle.
