Specifically, the tongue structure formed by stamping from the wire 100, additionally formed on the bottom case (10), locked to the bottom case (10) or integrally formed with the bottom case (10), is used as the wire displacement limiting device 300. In addition to the stencils, it is also possible to miscatch other items on top of them, such as plastic frames or glass. As shown in FIG. 3a, the backlight module assembly structure 9 can further be combined with the outer casing 200, the optical panel 4, and the optical film assembly 6A to form a perspective view of the north. The wire displacement limiting device 300 is preferably a metal, a metal alloy or a metal compound. The width of the wire locating groove 3 〇 0 can be adjusted according to the diameter of the two sets of 600 connected wires 301, preferably 2 is between 0.9 mm and 2 mm. Among them, since the wire 3〇1 is generally coated with a plastic material, the portion of the wire 301 and the wire positioning groove can be provided with a protective member to reduce the friction loss of the wire positioning groove 3 . The protective member is preferably, but not limited to, a heat-shrinkable sleeve, and is not limited to a partial arrangement, and may be disposed in the entire length of the wire 301. ' Sickle 9 200944878 A partial cross-sectional view of AA in Figure 3b is shown in red. In the preferred embodiment, the optical film set _ includes an optical film 610, a light guide plate 630, and a reflection plate 650. In the preferred embodiment, 'the optical film 610 is at least comprising a diffusion film, a gain film > 1 or a polarization," however, in other embodiments, the number of the optical film 61Q can be adjusted according to requirements. . The frame member 500 is disposed above the wire positioning groove 150. In the preferred embodiment, the frame member 500 is a polymer material. However, in various embodiments, the frame member 500 can be a metal, a metal alloy or a metal compound. As shown in Fig. 4a, the frame member 5 has a first side wing structure 51A, which is a ring flange inside the frame member 500, protrudes toward the center of the frame member 5, and is disposed opposite to the wire displacement restricting device_. Specifically, the first side wing structure 510 of the frame member 500 is supported by the displacement limiting device 300, so that the frame member _ can be placed above the wire positioning groove 15〇, thereby restricting the upward displacement of the wire 301, and the wire 3〇 The displacement of the left and right of the main body is limited by the wire displacement limiting device _ and the bottom case 100. & In other words, compared to the conventional frame member 50 of Fig. 1, the wire is required to be provided with a displacement restricting structure 5 to restrict the displacement of the wire 3〇1 to the left and right. The county module assembly structure of the present invention is illustrated by the frame member 500, the wire displacement limiting device 3〇〇 and the bottom case (10). The displacement of the wire 301 to the left and right is controlled by the wire displacement limiting device. The shell 1 is limited in common, and the frame 5 is only required to limit the upward displacement. Therefore, as shown in FIG. 1 and FIG. 4a, respectively, the frame and the coffee can be arranged without the need to set the displacement limit of the conventional frame, and the space required for the wire 301 is reduced by 200944878, and Further, an optical film group 600 having a large area can be used. Since the larger optical film group 600 can reduce the light leakage condition of the backlight module when the same size panel is used, the backlight module assembly structure 900 of the present invention can also reduce the light leakage condition of the backlight module. In the embodiment shown in Figure 4b, the frame member 5 further has a second side wing structure 520. The second side wing structure 52 is disposed opposite to the side edge 130 of the bottom case ❹ 1〇0. In other words, the second side wing structure 520 is supported by the side edges 130 of the bottom case 100. Since the first side structure 51G and the first side structure 520 of the frame member 500 can be supported by the two-wire displacement displacement 300 and the side 130 respectively, the frame member 5 can be more stably in this embodiment. It is disposed above the wire positioning groove 15〇. As shown in the preferred embodiment of Figure 4c, the frame member 5 further has a snap-fit structure 530 for engagement with the wire positioning slot 15''. Specifically, the engaging structure 530 can extend into the wire positioning groove 15 , to further fill the space outside the wire 301 of the wire filling groove 150 to more stably position the wire 301 in the wire positioning groove 15 . On the other hand, the frame member 500 can also be more stably disposed above the wire positioning groove 15A. As shown in FIG. 5, a method for manufacturing a backlight module of the present invention includes a method for manufacturing a backlight module according to the present invention. Step 1001 is to provide a bottom case 100 having an inner bottom surface J J 〇 and a side edge 13 如图 as shown in FIG. 4c. Step 1003 is to form a wire displacement limiting device 3 on the inner bottom surface no of the bottom case (10) 11 200944878, and form a wire positioning groove i5〇 with the side edge (10). In the preferred embodiment, the wire displacement limit is a tongue structure formed from the bottom shell. Wherein, the hole 101 formed by the scouring of the bottom case 1 can be further covered by the step (10) 3a by attaching a tape or the like to avoid light leakage. In various embodiments, the wire displacement limiting device 300 can be additionally formed on the money or integrally formed with the bottom casing (10). The tamper 1005 is assembled with an optical mold as shown in Fig. 4c on the inner bottom surface 110 of the bottom case. Specifically, the optical module is disposed in the bottom case 100 with respect to the inner bottom surface 11 of the other side of the wire positioning groove 150. Step 1007 is to have the optical mold (four) shown in FIG. 4c. The wire 301 is disposed in the wire positioning groove 15〇 to limit the displacement of the wire 15〇. Wherein, the protective member may be further disposed in the portion where the step 301 is in contact with the wire positioning groove 3GG to reduce the friction loss of the wire positioning groove 300. The protective member is preferably, but not limited to, a heat-shrinkable sleeve, and is not limited to a partial arrangement and may be disposed in the entire length of the wire 3〇1. Step 1009 is to place the frame member 500 as shown in FIG. 4c on the wire positioning groove 150 to limit the displacement of the wire 3〇1. The frame member has a first wing structure 510. When the frame member 5 is placed on the wire positioning groove 150, the first wing structure 5 is placed on the wire displacement limiting device 300 to support the frame member. . In a preferred embodiment, the frame member 5 can further have a second side wing 12 200944878 structure 520. When the frame member 500 is placed on the wire positioning groove 150, the second side wing structure 520 is placed on the side edge 13 to support the frame member 500. The frame member 500 further has an engaging structure 530 which is engaged with the wire positioning groove 150 by the engaging structure 53 when the frame member 500 is placed on the wire positioning groove 150. The backlight module manufacturing method of the present invention further comprises a step 1 of placing the optical panel 400 on the frame member 500, and the step 1〇〇9b placing the outer casing 200 on the optical panel 400 and the bottom case. 100 sets.
