[0002] The LCD display module is mainly composed of an LCD component, a backlight component and a backlight frame. In the related art, the LCD component is fixedly bonded to the backlight frame by double-sided adhesive. However, this structure has certain disadvantages. On the one hand, the service life of the double-sided adhesive is limited. Especially for use in an environment with large climate changes, the service life of the double-sided adhesive is shortened, and the viscosity is easily reduced, and there is a risk of the LCD component separating from the backlight frame. On the other hand, if the LCD display is abnormal and the LCD component needs to be replaced, the double-sided adhesive on the backlight frame is easily deformed and the viscosity decreases due to the removal of the LCD component. The backlight frame and the backlight component also need to be replaced together, which is not conducive to continued use.

[0038] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0039] like Figure 1-Figure 5 As shown, the LCD display module 100 includes a backlight frame 20 , a backlight assembly 30 and an LCD assembly 40 .

[0040] The backlight frame 20 includes a frame bottom 21 and a frame wall 22 disposed on the frame bottom 21. The frame wall 22 includes at least a first frame wall and a second frame wall opposite to the first frame wall.

[0041] A detachable structure is provided on the inner side of the frame wall 22. As an example, the detachable structure includes a buckle structure 23 provided on the first frame wall and a corresponding buckle structure 23 provided on the second frame wall. As another example (not shown in the figure), the detachable structure includes a buckle structure on the first frame wall and a corresponding groove structure provided on the second frame wall. This application does not make specific restrictions on this.

[0042] The backlight assembly 30 is positioned and connected to the backlight frame 20 and is located above the frame bottom 21 .

[0043] The LCD assembly 40 is detachably connected to the backlight frame 20 through the above-mentioned detachable structure; and the LCD assembly 40 is located above the backlight assembly 30, and performs liquid crystal display based on the backlight provided by the backlight assembly 30.

[0044] When the LCD display module 100 provided by the present application is used, a detachable structure is provided on the inner side of the frame wall 22 of the backlight frame 20.
