It can be understood that, since the inner side surface of the middle frame 300 is provided with the shielding part 301 and the connecting part 302, the middle frame 300 of the present application as a whole forms a structure of an F-shaped groove in cross section, and the structural strength of the middle frame 300 of the present application is improved compared with the middle frame 300 structure of some technologies which has a U-shaped groove 201 in cross section.

[0045] Optionally, the middle frame 300 and the third connecting wall 223 are bonded or connected through a screw 401, that is, the middle frame 300 and the third connecting wall 223 can be connected through a bonding or screw 401 fixing mode, and the specific mode can be selected according to actual needs.

[0046] For example, the outer side surface of the middle frame 300 and the third connecting wall 223 are bonded.

Wherein, the inner side of the third connecting wall 223 refers to the side of the third connecting wall 223 located in the U-shaped groove 201, and the outer side of the third connecting wall 223 refers to the side of the third connecting wall 223 located outside the U-shaped groove 201. Figure 9 and Figure 11 As shown in FIG. 13, a boss 2231 can be arranged on the inner side of the third connecting wall 223, the third connecting wall 223 is provided with a threaded hole 2232 extending to the boss 2231, the middle frame 300 is provided with a through hole 303, and the third connecting wall 223 is connected with the middle frame 300 by a screw 401 sequentially penetrating the through hole 303 and the threaded hole 2232. Specifically, as shown in FIG. 14, the through hole 303 is arranged on the connecting part 302, and the third connecting wall 223 is connected with the connecting part 302 by the screw 401 sequentially penetrating the through hole 303 and the threaded hole 2232, so as to realize the connection between the back plate 200 and the middle frame 300. Wherein, the inner side of the third connecting wall 223 refers to the side of the third connecting wall 223 located in the U-shaped groove 201, and the outer side of the third connecting wall 223 refers to the side of the third connecting wall 223 located outside the U-shaped groove 201.

[0047] It can be understood that when the middle frame 300 is connected with the third connecting wall 223 by the screw 401, the boss 2231 arranged on the inner side of the third connecting wall 223 plays a role of avoiding position, so as to avoid the screw 401 from protruding to the components (such as the diffusion plate 700 or the reflective sheet 800) located above the third connecting wall 223 and the like.

[0048] In some embodiments of the present application, the display panel 100 is connected with the outer side of the first connecting wall 221, the inner side of the first connecting wall 221 is provided with the wear-resistant piece 102; the display module further comprises an optical film sheet 500, the optical film sheet 500 is located between the display panel 100 and the back plate 200, and the optical film sheet 500 is connected with the inner side of the third connecting wall 223. Wherein, the inner side of the first connecting wall 221 refers to the side of the first connecting wall 221 located in the U-shaped groove 201, and the outer side of the first connecting wall 221 refers to the side of the first connecting wall 221 located outside the U-shaped groove 201.

[0049] Wherein, the optical film sheet 500 is used for improving the backlight effect of the display panel 100, and the optical film sheet 500 can be a polarized film for adjusting the polarization effect of light, a transparent film for improving the brightness of light, a diffusion film for improving the uniformity of light, or a filter film for filtering stray color light, etc., according to the different types, to adjust different backlight effects.

[0050] It can be understood that by arranging the wear-resistant piece 102, the friction between the optical film sheet 500 and the back plate 200 or the friction between the optical film sheet 500 and the display panel 100 can be reduced, so as to reduce the risk of the optical film sheet 500 being damaged by the back plate 200 or the optical film sheet 500 being damaged by the display panel 100.

[0051] Optionally, the display panel 100 is bonded with the outer side of the first connecting wall 221, that is, the display panel 100 is fixedly connected with the outer side of the first connecting wall 221 through the first adhesive 402. Optionally, the wear-resistant piece 102 is made of rubber or silica gel, for example, the wear-resistant piece 102 can be a rubber strip, a silica gel strip, a rubber block or a silica gel block.

Among them, the light source 600 is used to emit light, which can be an LED lamp (such as a mini LED lamp) or other types of lamps. The diffusion plate 700 is used to diffuse the light emitted by the light source 600 to form uniform light, thereby improving the color uniformity of the display picture of the display device.

[0053] Optionally, the optical film 500 is bonded on the side of the diffusion plate 700 facing the display panel 100, that is, the optical film 500 can be fixedly connected on the side of the diffusion plate 700 facing the display panel 100 through the second adhesive 403 (such as double-sided adhesive tape).

[0054] Optionally, the display module further includes a reflective sheet 800, the main body part 210 of the back plate 200 is recessed to form a receiving cavity 202 in the direction away from the diffusion plate 700, the reflective sheet 800 is arranged in the receiving cavity 202, and the light source 600 is connected to the reflective sheet 800. The reflective sheet 800 can be a thin film or a thin layer made of high reflectivity material, when the light emitted by the light source 600 reaches the reflective sheet 800, it will be fully reflected to the display panel 100, improving the light utilization rate and helping to provide high-efficiency backlight for the display panel 100.

[0055] In the prior art, the diffusion plate and the optical film are first mounted on the back plate, then the middle frame is fixed to the back plate by back locking screw, and finally the display panel is pasted to the middle frame by adhesive to complete the assembly of the display module. The existing assembly scheme has the problems of low production efficiency and foreign matter entering the module due to the back locking screw fixing of the middle frame and the back plate. In the present application, when the back plate 200 and the middle frame 300 are fixed and connected by the screw 401, the screw 401 can be pre-processed (i.e. the screw locking process 401 is moved forward), and the back plate 200 can be turned over when the screw 401 is locked, changing the original back locking screw 401 into a front locking screw 401, which greatly improves the production efficiency. In addition, by moving the screw locking process 401 forward, the fine particles or foreign matter generated during the screw locking process 401 can be cleaned, and after cleaning, the reflective sheet 800, the light source 600, the diffusion plate 700 and the optical film 500 are sequentially assembled into the back plate 200, and finally the display panel 100 is connected and fixed to the first connecting wall 221 of the back plate 200, completing the assembly of the display module, thereby effectively preventing foreign matter from entering the module and solving the problems of low production efficiency of the back locking screw 401 and foreign matter entering the module.
