达达号号: TW2717PA " IX. Description of the Invention: [Technical Field] The present invention relates to a backlight module, an assembly method thereof and a liquid crystal display device using the same, and in particular to a quick replacement of a light source The backlight module of the module, the assembly method thereof and the liquid crystal display device using the same. [Prior Art] Due to its thin size, poor space, low power consumption and low radiation pollution, the liquid crystal display device (LCD Device) has gradually replaced the traditional cathode ray tube (Cathode Ray Tube). , CRT) display device, become the standard equipment of a new generation of computers. The backlight module in the liquid crystal display device is used to provide a uniform light source to the liquid crystal display panel, thereby presenting a bright and rich face. Referring to Fig. 1, there is shown a partial cross-sectional view of a conventional liquid crystal display device. The liquid crystal display device 103 includes an outer frame 105, a backlight module 100, a first polarizing plate 142a, a second polarizing plate 142b, and a liquid crystal display panel 150. The backlight module 1 includes a frame 110, a back plate 120, a tube 130, a diffusion plate 138, and an optical film 140. The lamp tube 130 is disposed on the back plate 120, the diffusion plate 138 is disposed on one of the support portions 122 of the back plate 120, and the optical film 140 is disposed on the diffusion plate 138. Through the assembly of the frame 110 and the back plate 120, the diffusion plate 138 and the optical film 140 can be disposed in the backlight module 1A. The side plate 121 of one of the frames 110 and one side plate 123 of the back plate 120 are fixed to each other. The first polarizing plate 142a is disposed on the frame 110, and the liquid crystal display panel 150 is disposed on the first polarizing plate 142a 5 200844549

Two rules a / ΰ · TW2717PA * on. Further, the liquid crystal display panel 150 is sandwiched between the polarizing plate 142a and the second polarizing plate 142b. The first polarizing plate 142a, the second polarizing plate 142b, and the liquid crystal display panel 150 can be disposed on the backlight module 100 via the assembly of the outer frame 1 〇 5 and the frame 11 。. However, in the conventional backlight module 1 described above, when the lamp tube 13 is replaced, the outer frame 105 and the frame 11 are first separated to remove the first polarizing plate 142a, the second polarizing plate 142b, and the liquid crystal display panel. 150. Next, the frame 110 and the backing plate 120 are separated to take out the optical film 140 and the diffusion plate < 138. Finally, the damaged lamp on the backing plate 120 can be replaced. When the lamp is to be replaced, all the components of the above liquid crystal display device 1〇3 must be combined to the previous state in a step-by-step manner. From this point of view, the traditional step of replacing the lamp tube of the backlight module is both cumbersome and time consuming, and is not economically advantageous. Further, during the process of loading and unloading the first polarizing plate 142a, the second polarizing plate 142b, the liquid crystal display panel 150, the optical die 140, and the diffusing plate 138, damage of such components is liable to occur. As for other backlight modules using light-emitting diodes as light source components, the above problems are also encountered. Therefore, how to reduce the steps of replacing the light source components and improve the assembly efficiency is one of the important goals that are currently to be solved. SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a backlight module in which a connector is detachably connected to a frame and a back plate. Therefore, when replacing a damaged light source assembly, the new light source assembly can be replaced simply by separating the back plate from the connector. It is not necessary to remove the diffuser plate and the optical film first, and then the light source component can be replaced after the connector is separated from the frame. This can avoid damage to the diffuser plate and the optical 6 200844549
