The above and other objects, features, and advantages of the present invention will become more apparent from the description of the appended claims appended claims [Embodiment] 1247171 13968.twf.doc/m FIG. 3 is a schematic view showing a liquid crystal display according to an embodiment of the present invention, and FIG. 4 is an exploded view of the backlight module of FIG. Referring to FIG. 3 and FIG. 4 simultaneously, the liquid crystal display 200 is mainly composed of a liquid crystal display panel 21A and a backlight module 220. The backlight module 220 is mainly composed of a first frame 230, a light guide plate 240, at least one reflector 250, at least one linear light source 260, and at least one positioning member 270. In the present embodiment, the number of the reflection cover 250 and the linear light source 260 is exemplified by two groups, and each of the linear light sources 260 is matched with two positioning members 270, for example. The first frame 230 has a bottom plate 232 and a plurality of side plates 234 that vertically connect the periphery of the bottom plate 232. The light guide plate 240 is disposed on the bottom plate 232 of the first frame 230 and has a light incident surface 242. The light guide plate 240 of the present embodiment is, for example, a flat plate type light guide plate. Of course, the light guide plate 240 may also be a wedge type light guide plate. The reflector 25 is assembled to the side of the light guide plate 240 and is located beside the light incident surface 242. The linear light source 260 is disposed between the light incident surface 242 of the light guide plate 240 and the reflective cover 250. The positioning member 270 is assembled to one end of the linear light source 260. The linear light source 260 is, for example, a Cold Cathode Fluorescent Lamp (CCFL) or a Light Emitting Diode (LED) array. As shown in FIG. 4, the backlight module 220 further includes a second frame 280 and at least one optical film 290. The second frame 280 is assembled to the first frame 230 for fixing the light guide plate 240 between the first frame 230 and the second frame 280. The optical film 290 is disposed on the light guide plate 240. The optical film 290 of the present embodiment is, for example, a prism or other optical film used to increase the brightness and uniformity of the surface light source provided by the south backlight module 220 by 1247171 13968.twf.doc/m. FIG. 5 is a perspective view of the positioning member according to the embodiment of the present invention, and FIG. 6 is a green view showing the combination of the positioning member and the adjacent component of the embodiment. Referring to FIG. 5 and FIG. 6, the positioning member 27 has One card is provided with a slot 272 2 榫 276. Wherein one side of the reflection 25 及 and the first frame 2 234 are adjacent to the reflector, one of the side cards is placed in the card slot milk = and the reflection cover 250, the card 276 via the positioning member 27 and the positioning Pieces 27, line combination. However, the reflecting cover 25G may be combined with the positioning member 270 by other means such as screws, and is not limited to the cassette 276. FIG. 7 is a perspective view of a positioning member according to another embodiment of the present invention. Referring to FIG. 6 and FIG. 7 simultaneously, the positioning member 27〇b is different from the positioning member 27〇 described above in that a first locking groove 272b and a second clamping groove 274b are provided. Wherein, one side of the reflector 250 is snapped into the first latching slot 272b of the positioning member 27A. One of the side plates 234 adjacent to the reflector 25 is placed in the second latching groove 2741) of the positioning member 270b. Referring again to Figure 6', the keeper 250 is secured to the side panel 234 by its grooving slot 272. Therefore, the positioning member 270 can be used to avoid a shift between the reflector cover 250 and the first frame 222. As a result, the assembly speed of the backlight module 220 can be accelerated. Referring to FIG. 4 and FIG. 6 again, in general, the wire 310 for supplying the power source required for the linear light source 26 is connected to the linear light source 260 through the positioning member 270. Therefore, when the backlight module 220 is inspected, the operator often has to The wire 310 is pulled out for the test of lighting. In this embodiment, since the positioning member 270 is fixed on the side plate 234, the displacement of the wire 31〇 is not caused by pulling 1247171 13968.twf.doc/m, and the linear light source 26〇 can be prevented from being broken. phenomenon. In summary, in the backlight module of the present invention and the liquid crystal display state using the backlight module, the reflector is mainly used to sandwich the reflector and the first frame, so that the reflector and the side plate of the first frame are There is no offset when assembling. In this way, the assembly speed of the backlight module can be accelerated. In addition, since the positioning member is fixed to the first frame, displacement is not generated when the wire is pulled, and the product yield of the backlight module can be improved. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and it is to be understood that those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is subject to the definition of the scope of the patent application.
