Embodiment Construction
[0021] First, see Figure 4 . Figure 4 It is an exploded view showing the structure of the backlight module 20 utilizing the new frame structure of a preferred embodiment of the present invention. As shown in the figure, the backlight module is mainly composed of a plastic upper fixing frame 21, an upper diffusion plate 22, a light enhancement film 23, a lower diffusion plate 24, a light guide plate 25, a light source group and a metal or plastic lower fixing frame. The frame 26 is assembled sequentially from top to bottom; where the above-mentioned backlight module assembly is completely fixed by using the upper fixing frame and the lower fixing frame to achieve integration. The upper fixing frame has a fitting element that simultaneously restricts lateral movement and longitudinal movement, and the lower fixing frame has a corresponding fitting member that cooperates with the fitting element. For the specific structure of the fitting element and the corresponding fitting m...
