[Prior Art] In recent years, with the advancement of the 3C industry, liquid crystal displays (LCDs) have been widely used in notebook computers, desktop computers, and personal digital assistants (PDAs, Pers〇nal Digi(4) Assistant. )Wait. The liquid crystal display comprises a liquid crystal display panel (LCD panel) and a backlight module. The liquid crystal display panel is mainly composed of a color filter, a driving IC 'compensation film and a polarizing plate, a glass substrate, an ITO film, an alignment film, a control circuit and the like. Components are composed. In general, the backlight module can be divided into two types: direct-lit and side-lit. Since the liquid crystal itself does not emit light, the backlight module must be used to supply a sufficient light source with uniform brightness and uniform distribution to enable normal display of images. Referring to FIG. 1 , a liquid crystal display device includes a liquid crystal display panel 1 and a backlight module 2 , and the backlight module 2 mainly includes a light source 21 (llght somxe), a light guide plate 22 (llght guide plate), and a diaphragm. Four parts, such as a 23 (mm sheet) and a frame 24 (mo]d frame, wherein the light source 21 has a cold cathode fluorescent tube or LED 211, and a light source mirror 212; and the diaphragm 23 has A film 23 1 , a reflective film 232 and a diffusion film 233 are formed. In the fixing of the diaphragm 23, the diffusion film 233 and the reflection film 232 are fixed in such a manner that the diffusion film 233 and the reflection film 232 are close to the end of the light source 21, and the upper and lower ends of the 233 and 232 are doubled. The surface tape u is adhered to the s-light source mirror 2 12 and the light guide plate 2 2 , and the purpose is to effectively prevent the film 23 from falling off when the backlight module 2 and the liquid crystal display panel 1 are assembled. Shift. Referring to FIG. 2 to FIG. 4 ′, another diffusion mode of the conventional diffusion film 233 and the reflective film 232 is divided into an upper diffusion film 234 and a lower diffusion film 235 , and the upper diffusion film 234 and the lower diffusion film The film 235 and the ruthenium film 231 form two lugs 236 on one side of the non-light tube. Further, the left and right sides of the upper diffusion film 234 form two other square ears 237. The fixing method is not completely double-sided tape U bonding method as in the above method, as shown in FIG. 2, the fixing manner of the lower reflecting film 232 is directly embedded between the light source reflecting mirror 212 and the light guiding plate 22, as shown in FIG. The upper diffusion film 234 ′ and the second diffusion 236 of the prism film 231 are respectively embedded in the through grooves 242 of the two fixing portions 241 of the frame 24, and the upper diffusion film 234 is The 234 square ear 237 is adhered and fixed to the left and right sides of the top surface of the frame 24 by the double-sided tape 11. The above-mentioned two conventional fixing methods show some disadvantages in the actual mass production experience. The key point is that the upper diffusion film 234 is fixed by the lug 236 and adhered to the frame 24 by using the double-sided tape n. . In the state where the moonlight module 2 is lit for a long time, the cold cathode fluorescent lamp or the LED 211 generates heat to increase the temperature of the backlight module 2, and the upper diffusion film 234 is generally a polyethylene pair. As a material, p〇lyethyiene Terephthalate (PET, hereinafter referred to as pET), in such an environment 1320116, PET will be heated and stretched, as shown in Figure 4, since the left n-system of the upper diffusion film 234 has been The double fabric u has its upper diffusion film 234 square ear 237 adhered to the frame 24, so that the left and right ends of the upper expansion film 234 are confined by the double-sided tape n, resulting in an upper diffusion film. 234 A situation in which the curved varicose is generated upward or downward due to the torsion generated by the heat extension. The result of the upward diffusion of the upper diffusion film 234 will cause the upper diffusion film 234 to be in contact with the liquid crystal display panel i above the 234, and the result of the downward splaying causes the upper diffusion film 234 to touch and squeeze the edge below the 234. Mirror film 231. In either case, the film 23 is severely touched by other components, and the defect is caused by unevenness (Backllght, a phenomenon in which uneven brightness of the display causes various traces). In addition, if the diaphragm 23 is in a problem such as scratches, in the process of performing the backlight repair, the upper diffusion film 234 and the double-sided tape 11 need to be manually scraped from the frame 24 to be replaced. Actions are not only time-consuming and laborious, they are more likely to damage the framework and other components. SUMMARY OF THE INVENTION One object of the present invention is to provide an optical film fixing method in which an optical film can be fixed and a backlight unevenness is avoided. Another object of the present invention is to provide a combination of a backlight module capable of reducing backlight repair time and improving the efficiency of liquid crystal display mounting. Another object of the present invention is to provide a liquid crystal display backlight module using the combination of the housings. Thus, the present invention is used in a frame combination of a backlight module, which includes - 7 1320116
