The upper diffusing plate 12 is attached to the light box in the process of "whitening", and the double-sided adhesive is attached to the bearing edge 141 by manual means, and then the expansion board 12 is attached. The double-sided tape is applied to the double-sided tape to be fixed to the light box Η. This method not only consumes labor, increases processing costs and processing time, but is more complicated and difficult if full inspection (·ΐιη§) is required. 'Therefore, it is necessary to provide an innovative and progressive backlight module light box to solve the above problems. SUMMARY OF THE INVENTION The main purpose of the invention is to provide a first connection device in the box of the backlight module, and to add a second connection device corresponding to the first connection device on the diffusion plate. The cooperation between the first connecting device and the second connecting device can facilitate the assembly work on site, which not only saves the process of attaching the double-sided adhesive, but also saves labor cost and processing time. Moreover, if the diffuser plate is to be removed from the light box, it is simpler and easier than the conventional one, and it is not easy to remove the double-sided tape, thereby deteriorating the flatness of the surface of the original structure. [Embodiment] Referring to Figures 3 and 4, a perspective view of a backlight module according to a first embodiment of the present invention is shown. The backlight module 2 includes a light source and a plate body that can uniformly diffuse the light source, a reflection plate 23, and a light box. In this embodiment, the backlight module 2 is a direct-type backlight module and is located below a liquid crystal panel (not shown) in a liquid crystal display. However, the present invention is not limited to the direct-lit backlight module. 0 View 88329 -6- 1260452 The light source is a plurality of tubes 2 1, and the tubes 2 1 may be camping tubes for providing a light source. The plate system capable of uniformly diffusing the light source is a diffusion plate 22, which is disposed above the lamps 21, and is usually made of polymethylmetharylate (PMMA) or polycarbonate. A PC (polycarbonate) is used to uniformly diffuse light emitted from the tube 21 to the liquid crystal panel. The reflector 23 is disposed under the tubes 2 1 and is made of a conventional reflective polycarbonate or polyethylene terephthalate reflector for the tube 2 The light diverging to the bottom of the backlight module 2 is reflected to the diffusion plate 22. The housing 24 is a rectangular frame for accommodating the lamps 21, the diffusing plate 22 and the reflecting plate 23, and includes a bearing edge 2 for the diffusing plate 2 2 to bear. 41, the bearing edge 2 41 is disposed around the inner side of the light box 24. The main feature of the present invention is that the bearing edge 241 of the light box 24 has at least one first connecting device, such as the block 2411 in the figure, and the diffusing plate 22 has a second connection corresponding to the first connecting device. The device, such as the through hole 221 in the figure. The height of the block 2411 is approximately 1 mm, and the number and distribution position thereof may be determined according to actual needs. In this embodiment, the outer diameter of the block 2411 is slightly larger than the outer diameter of the through hole 221, so that the block 2411 and the diffuser plate 22 are tightly coupled and fixed to each other. Referring to Figure 5, there is shown a perspective view of a card block in accordance with a first embodiment of the present invention. In this embodiment, the block 2411 is a rectangular cylinder and is integrally formed with the light box 24; however, in other applications, the block may be a cylinder. In addition, the peripheral surface of the block 24 11 may be

In the present embodiment, the surface of the block 24 11 is in the form of a zigzag shape to increase the friction between the block 24丨1 and the through hole 22. Referring to FIG. 6, there is shown another surface appearance of the card block according to the first embodiment of the present invention. The surface of the card block 2411 is composed of a plurality of grooves, and the card block 24 11 and the through hole are also added. 22 1 friction. Referring to Fig. 7, there is shown a perspective view of a card block in accordance with a first embodiment of the present invention, wherein the surface of the card block 411 is planar. Referring to Figures 8 and 9, there is shown a perspective view of a backlight module in accordance with a second embodiment of the present invention. The backlight module 3 of the embodiment is substantially the same as the backlight module 2 of the first embodiment, and has a plurality of lamps 31, a diffusion plate 3, a reflector 3 3 and a light box 34. The light box 3 4 There is likewise a bearing edge 341 which can be supported by the diffuser plate 32, which also has a catch 3411. The difference between the embodiment and the first embodiment is that the position of the block 3 411 of the embodiment is attached to the side wall of the outer edge of the remote bearing edge 3 41. Therefore, the side of the diffuser plate 32 corresponds to the card. An opening 32 1 is formed at the position of the block 3411. Therefore, when the material thickness of the diffusion plate 32 is thin, the through hole is added to the side of the diffusion plate to cause breakage. The utility model has the advantages that the engagement between the card block and the through hole can facilitate the assembly work on site, which not only saves the process of affixing the double-sided adhesive tape, but also saves labor cost and processing time, and further makes the diffusion plate The disassembly and assembly of the light box is possible and very convenient. The above embodiments are merely illustrative of the principles and effects of the present invention, and are not limiting.
