The limiting part 241 can be provided with one or more, which is not limited here. In this embodiment, the installation groove 240 is provided with two limiting parts 241, and the two limiting parts 241 are relatively provided on the two groove walls of the installation groove 240.

[0054] In one embodiment, referring to Figure 12 to Figure 14 As shown, the display device further includes a backlight module 3, which is fixedly connected to the aluminum frame 100 and is located on a side of the aluminum frame 100 away from the plastic frame 200. Specifically, the backlight module 3 is used to supply the display device with sufficient brightness and uniformly distributed light source, so that the display device can display images normally. One end of the backlight module 3 is fixedly connected to the aluminum frame 100, and the backlight module 3 is located on a side of the aluminum frame 100 away from the plastic frame 200, thereby improving the structural strength of the display device.

[0055] In particular, the display device also includes screws, and the backlight module 3 includes a through hole; the aluminum surface frame 100 includes a threaded hole, and the screw passes through the through hole and is locked with the threaded hole to fix the backlight module 3 on the aluminum surface frame 100; the backlight module 3 also includes a backlight supporting surface 600, and the aluminum surface frame 100 also includes a surface frame supporting surface 120, the through hole is arranged on the backlight supporting surface 600, and the threaded hole is arranged on the surface frame supporting surface 120, the backlight supporting surface 600 is in contact with the surface frame supporting surface 120, and the screw tightly fits and fixes the backlight supporting surface 600 and the surface frame supporting surface 120, thereby improving the structural stability of the display device, and finally assembling the display device into a complete machine state.

[0056] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
