Description of the Invention: [Technical Field] The present invention relates to a backlight module, and more particularly to a direct type backlight module. [Prior Art] A backlight module (BackLightModule) is used in a liquid crystal display (LCD) to provide a uniform, high-brightness backlight for a liquid crystal display panel (LCD panel). The backlight module can be divided into two types according to the position of the lamp tube, one is an edge-lit backlight module, and the other is a direct-lit backlight module, wherein the lamp of the edge-lit backlight module is disposed on the side, the lamp The light generated by the tube must be guided through a light guide plate disposed on one side of the light tube, and uniformly emitted through the optical film disposed above the light guide plate, so that the light is irradiated to the liquid crystal display panel in the form of a uniform surface light source. The lamp tube of the direct type backlight module is disposed at a position below the liquid crystal display, and the lamp tube is generally arranged in a plurality of rows side by side, and the generated light is uniformly irradiated to the liquid crystal display panel by the action of the reflector and the diffusion plate. The direct-lit backlight module has high light conversion efficiency in converting the line source of the lamp into a surface light source, and is not limited to the size of the liquid crystal display panel, so it is more suitable for use in a liquid crystal display having a large display area. Referring to the cross-sectional structural diagram of the conventional direct-lit backlight module 9 and the liquid crystal display panel 8 shown in FIG. 1 , the conventional backlight module 9 provides a backlight for the liquid crystal display panel 8 , which mainly includes a frame 9 . A reflector 92, a plurality of lamps 93 and a diffuser 94. The frame 91 has a bottom plate 910 and a side wall 912 located around the bottom plate 910. The reflector 92 is disposed on the bottom plate 910 of the frame 91. The diffuser plate 94 is supported by the side wall 912 of the frame 91. Between the reflector 92 and the diffuser 94, the lamps 93 are arranged at a constant pitch. . However, the diffusing plate 94 is easily recessed downward in the gravity setting, especially in the movement of the liquid crystal display or the transportation of the transport wheel. The diffusing plate 94 is more likely to sag downward and sag downward, and this recess will not only affect the shadow _ 槪The slab should have a silk record, which is more likely to cause it to rupture', so that the quality of the backing group 9 cannot be obtained. In order to solve the above problem, a plurality of supporting means are usually disposed between the diffusing plate 94 and the bottom plate 91 of the frame 91, and the ribs are cut to prevent the thief plate 94 from being recessed downward. In the second figure, the support I is installed in the backlight module 9. The cutting device 7 pack 3 has a tapered continuous body 71 and a hook hook at the bottom of the support ship 71.

Although the conventional κ can prevent the diffusion plate 94 from being recessed downward, the tapered support body is extremely easy to erect the expansion plate 94', especially when the scatter plate is subjected to external force, such as when bumps occur during the transfer process. Since the conventional support 7 has no elastic buffering ability, the external force cannot be reduced, so that the diffusion plate 94 can only receive the upward reaction force from the support body force, and the diffusion plate 94 is easily damaged. The top display does not show that the support device 5 is installed in the backlight module 9. The cutting device 5 includes a --cone-shaped branch body 51 and a fixed inspection under the support body 51, and the periphery of the fixing bolt 52 is provided with a spring 53 having a screw hole. When the supporting device 5 is mounted on the bottom plate _ of the back group 9, the fixing bolts & protrude into the mounting holes of the bottom plate 200909925, and the support device (4) is slid into the screw holes of the measuring pin 52 by a screw 54 It is fixed on the bottom plate 91G. The spring 53 is located between the bottom plate _ and the cutting body 51, and is supported by the spring 53 to support the device 5 with the ability to be miscellaneous. However, the supporting device 5 includes a plurality of mutually separated components such as the fixing bolt 52, the spring 53 and the screw %, and the bolt 52 or the like is required to be assembled by _54, resulting in an increase in the number of parts and complicated assembly steps, which is disadvantageous. cut costs. Therefore, it is necessary to provide a new type of support device to solve the defects in the prior art.

Further, a reflecting plate 92 may be disposed between the bottom plate 91 of the lamp scale device 6 91 91, as shown in Fig. 4B. Since the supporting device 1 of the backlight module 9 of the present invention is provided with two connected elastic arms 21, an elastic buffering effect can be formed on the diffusing plate 94, and the supporting device 1 can be directly clamped by the folding portion 12 The device 6 or the xenon tube clamping device 6 is integrally formed and then mounted on the bottom plate of the frame 91 without screw locking. The number of parts of the entire supporting device is small, the assembly procedure is simple, and the cost is reduced. Referring to the third embodiment of the present invention shown in FIG. 6, the biggest difference between the supporting device 3 of the present embodiment and the supporting device 2 of the second embodiment and the second embodiment is that the supporting device of the present embodiment is 200909925. A receiving cavity 31 is formed in the middle portion of the main body 30, and a lamp loss holding seat 33 is disposed in the receiving cavity; and the main bodies 10 and 20 of the supporting devices 1 and 2 of the first and second embodiments are a column. The lamp body is not provided with a lamp holder. Referring to FIG. 6 , the support device 3 of the third embodiment of the present invention includes a main body 30 ′ formed in a middle portion of the main body 30 with a 匚-shaped receiving cavity & Opening 310. The support device 3 further includes two elastic arms 32 and a lamp holder 33. The two elastic arms 32 are symmetrically disposed on one of the end faces 301 of the main body 3, and the lamp holder 33 is c. The structure is disposed in the receiving cavity 31 for holding the lamp tube, and the orientation of the opening 33 of the lamp holder 33 is aligned with the orientation of the opening 310 of the receiving cavity 31 to facilitate the lamp from the opening 31. The crucible enters the lamp holder holder 31. The supporting device 3 of the towel of the embodiment has the functions of supporting the diffusing plate and the lamp tube at the same time, and the structure for completing the two functions is a body design, so that the assembly time can be saved. More importantly, the spring tube 32 is disposed on the top end surface of the branch unit 3, and the tube holder 33 is located below the elastic arm η. Therefore, when the diffusion plate is recessed by an external force, the elastic arm 32 will be elastically deformed to reduce a part of the external force acting on the diffusion plate; at this time, the elastic deformation of the elastic arm 32 does not affect the lamp tube clamping. The upper position of the seat 33. In other words, the hybrid operation of the present invention does not cause the lamp to jump up and down, thereby preventing the lamp from rupturing. The third solid surface supporting device 3 of the present invention is further provided with a fixing portion 34' on the other end surface 3〇2 of the contact body, which can be directly assembled to the bottom plate of the backlight module by the fixing portion 34. Referring to the support device 1 of the first embodiment (as shown in FIG. 4B), the support 12 200909925 support device 1 is first assembled on the substrate and then assembled in the backlight module 9. Of course, the supporting device 3 of the third embodiment of the present invention can also refer to the supporting device 2 'reading device 2 - substrate & body forming in the second embodiment (as shown in the figure), and then Assembled in backlighting her. Therefore, the electrical installation method of the 3 light-emitting module 9 of the original and the fine-fixing device.
