功能即在於供應充足的亮度與分佈均勻的光源，使其能正常顯示影像。 背光模組可分為側光式與直下式兩種形式，其中，直下式背光模組其 主要由光源、反射片(Reflector)、擴散板(Diffiision plate)、擴散片(Diffusion sheet)、增光片(Brightness enhancement film)等等光學膜片及框架等組件組裝 而成。發光源射出的光線進入擴散板後，會導引射入的光源將其分佈成均 勻的面光源，位於光學膜片—側之反射片會將射向反射片方向的光反射回 φ 擴健中’防止光源外漏’以增加光的使用效率。由擴散板射出的光線再 經擴散片的均光作用與增光>{的集光作用，提高絲的亮度與均勻紐， 再將光線射入液晶面板内。 . 發光二極體似幽Emitting Diode，LED)具有區域控制、驅動快、避免殘 、

Description of the Invention: [Technical Field] The present invention relates to a backlight module, and more particularly to a backlight module having a fixed substrate and a fixed structure supporting the optical film. [Prior Art] The backlight module (Backlight module) is one of the key components of the liquid crystal display panel (Uquid Crystal). Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness. With a well-distributed light source, it can display images properly. The backlight module can be divided into two types: a side light type and a direct type. The direct type backlight module mainly comprises a light source, a reflector, a diffusion plate, a diffusion sheet, and a brightness enhancement sheet. (Brightness enhancement film) and other components such as optical film and frame assembly. After the light emitted by the light source enters the diffuser, it will guide the incident light source to distribute it into a uniform surface light source. The reflective film on the side of the optical film will reflect the light in the direction of the reflective sheet back to φ. 'Prevent the light source from leaking' to increase the efficiency of light use. The light emitted by the diffusing plate is further subjected to the light collecting action of the diffusing film and the light collecting effect of the lightening light to increase the brightness and uniformity of the wire, and then the light is incident into the liquid crystal panel. Light-emitting diodes (Emitting Diode, LED) have regional control, fast drive, avoiding residue, 35, mercury-free (four)' is the trend to replace the cold cathode lamp (CCFL) with a light-emitting two-station as a light source. Improving the assembly method of the fixed structure and the number of components contribute to the production capacity. Please refer to FIG. 1 , which is a schematic diagram of a prior art backlight module 1 . The backlight module 100 includes a frame 110, a substrate 120, a plurality of light emitting diodes (2), a reflective sheet (2) 5 1377403, and an optical film 140. The substrate 120 carries the plurality of light-emitting diodes 12 and the reflective sheet 123 is placed on the substrate 120 for reflecting the light generated by the light-emitting diode 121. The diffusion plate 140 is disposed on the reflection sheet 123 for diffusing the reflection sheet 123 and the light emitted from the LED 201. The frame 110 is for accommodating the substrate 120, the plurality of light-emitting diodes 121, and the reflective sheet 123 to avoid the influence of external dust. The substrate 120 is locked to the screw hole 112 of the frame 110 by an opening 122 through which the screw is passed through the substrate. When the screw 111 is locked with the screw hole 112, since the height of the screw ill is insufficient to resist the diffusion sheet 140', an additional at least one floor mechanism 150 is required to resist the optical film 140 to prevent the optical film 140 from being placed. Deformed in the frame no. In addition, in the backlight module 1' of the prior art, the screw 111 is fixed to the screw hole 112 of the frame 11 by the opening of the upper and lower through substrate 120 to fix the substrate 120. The method is not easy to locate, and the triggering light diode 121 causes damage. SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a fixed ridge structure having both a fixed and a supporting function to replace the conventional snail hole fixing gorge to solve the above problems of the prior art. The embodiment of the present invention provides a backlight module including a frame, a light source module, and a plurality of structures. The stretcher contains a comprehensive joint. The system includes at least one base plate, a plurality of point light sources disposed on the wire plate, and a plurality of openings in the substrate. The at least one portion of the fixed structure includes at least one upper portion and at least one lower portion, wherein at least a portion of the lower portion of the fixed structures pass through the openings of at least a portion of the light source module, The U-shaped top ends of the at least one portion of the fixed structures are substantially equal to or equal to at least a portion of the top ends of the point light sources. The embodiment of the present invention provides a method for assembling a backlight module. The backlight module has a multi-axis joint portion, and the light-receiving group has at least a substrate and a plurality of points disposed on the substrate. And the plurality of openings and the plurality of side structures in the substrate, at least a portion of the EI fixed structure includes at least an upper portion and at least a lower portion, the method comprising: placing the optical homing frame; And engaging at least the lower portion of the at least one portion of the substrate with the openings of at least a portion of the substrate, and engaging at least a portion of the joints of the frame, wherein at least a portion of the The top end of the upper portion of the surface-defining structure is substantially higher than or equal to at least a portion of the top ends of the plurality of point sources. An advantage of the present invention is that it embosses the structure to the extent of the substrate and supports the optical film, which is easy to remove and replace, and does not require additional support to resist the optical film.
