Description of the Invention: [Technical Field] The present invention is a kind of optical film structure in a backlight module, especially a backlight module. [Prior Art] According to the main source of light source of the liquid crystal display, the surface light source device is used to provide uniform, partial party and wide viewing. The surface light source device comprises at least a backlight module and a front light module. Press, the conventional backlight module i, please refer to Figure 1, the #光模块 is mainly composed of frame 11, reflector 丨2, light guide 丨3, optical diaphragm 丄4 and light source single 7〇1 5 (such as a cold cathode lamp), the frame i frame i work and has one or more stagnation ii 2, and formed by the inner edge of the frame 11 inwardly - the valley area 113, The accommodating area 丨i 3 can be arranged with the reflecting plate i 2 and the light guiding plate 13 in sequence, and the optical guiding plate 13 is provided with an optical 丨 4, and the optical film 14 includes a diffusion film 141 and a cymbal 142. The function of the cymbal 14 2 is to correct the optical direction, so that the light needle is in the direction of the front surface, and the undulating diaphragm 丄 4 1 has an effect of spreading and uniformizing the light, and also has a covering effect. The diaphragm 1 4 1 corresponds to the slot 12 12 in the frame 1 1 1 of the frame 1 1 and has a lug 1411; the light source unit 5 is provided with a mosquito element 15 1 in an elastic material, and The side of the light source unit 15 is covered with a reverse 12.85285. The reflector 16 is mainly for increasing the light transmittance, and the reflector 16 is fixed to the frame by the screw member 丄7. The side of the frame. The lug Η! i of the diffusion diaphragm 141 can be embedded in the recess 112 of the frame 1 1 frame (1), as shown in Fig. 2, and then the components are assembled and assembled in sequence. 〃 When the white light module 1 is assembled, the light source unit 15 is first placed in the side edge of the frame 11, and then covered by the reflector i 6 , and the reflector 11 is fixed to the frame by the screw solid element. 1 i side end; of course, the light source unit 15 can be placed on the reflection g 1 6 towel, and then the reflector 1 6 ' with the light source unit 15 is provided to the mosquito frame! ^ Edge; then the light guide plate 丄 3 is placed in the accommodating area 11 ^ ' of the frame 11 and the light side end i 31 of the light guide plate i 3 is dropped into the opening portion of the reflection H i 6 to be mounted and positioned, and finally sequentially The prism sheet 14 2 of the optical film 14 and the diffusion film cutter 4 are placed on the light guide plate 3. The conventional backlight module 1 is formed by the lug 1411 formed by the side of the diffusion film i 4 i. Let it achieve the effect of temporary positioning, and then install the other elements to the 'only' due to the diffusion diaphragm! There is a prism sheeter 4 2 below the 4!, and the cymbal 142 has the effect of a branch, and the optical film 丄 (10) is placed in the frame 111 of the frame 11, and when the unit is ignited, the light source will Since the light is reflected by the frame 111, the light of the diffusion film 14 i is generated, resulting in uneven light emission of the backlight module 1. θ, most of the industry is known as gram _ _ _ i 4 ^ will be the red line of the disadvantages of the second, the sash 3 along the diffusion film 'such as the light-shielding tape a can effectively prevent the diffusion of 丄 丄^周略', by the backlight module 1 can be turned out. The seat is cumbersome, and when the sun is covered, the lug l4Uf is covered by the lug 1411.

In order to reduce the dark band phenomenon caused by the coating of the light-shielding strip of the optical film, the optical mode is turned to output a light source with high brightness and high brightness, so as to improve the overall light-emitting efficiency. [Embodiment] ▲ In order to make it easier for the examiner to understand the structure of the present invention and the achievable effect of the present invention, the following description is given: First, referring to FIG. 5, the back group 3 of the present invention is mainly composed of the frame 3 1 , the reflector 3 2, the light guide plate 3 3, the optical film 34 and the light source unit 35, the frame 3 1 1 of the frame 3 1 is provided with a money slot 3 i 2 , and is inwardly surrounded by the periphery of the frame 3 1 The accommodating area 3 i 3 is formed, and the accommodating area 3 is sequentially disposed with a reflecting plate 3 2 and a light guide plate 33. The light guiding film 3 is provided with an optical film 34, and the optical film 34 includes There is diffusion 3 4 ! and 稜鏡 3 4 2, the role of the lens 342 is to correct the direction of the light source, so that the light is concentrated in the desired direction, the diffusion > { 3 4 1 for the light source to spread, all from the wire, also has a covering effect, and the diffusion film 3 4 i corresponds to the frame 3 i of the frame 3 i; The lug 3 4 i丄 is disposed, wherein the diffusion film 3 4 9285285 is coated with a light shielding tape c 1 in the printing manner, and the light shielding tape C forms a can e corresponding to the lug 3 4 1 1 ; The light source unit 3 5 is provided with a fixing member 351 made of an elastic material, and the faint light group 35 - her financial reflection (5) 6 'the reflection H 3 6 mainly rides the light of the alcohol, and the reflector 3 6 is fixed to the side of the frame 3 2 by means of a screw-solid element 37. Referring to Figure 6, the present invention is provided with a lug 3 411 ' on the side of the diffusion diaphragm 34. The optical film 34 is brought into a temporary positioning effect, and then the other components are assembled in a group. The peripheral film of the diffusion film 3 41 is coated with a fC' to make the backlight module 3 emit light. 4 The edge of the cover hc can prevent the diffusion (4) 3 4 1 around the bright line, so that the backlight module 3 can be transmitted to a uniform light source. The lug 3 411 is formed as a concave arc c1, so that the backlight module 3 can be used to prevent the light and dark drop of the light at the lug 3 411 from being excessively formed to form an appearance defect. It can evenly illuminate, and the shading band c and the concave arc at the lug ^ 1 can be completed only by _ times, and the processing time of the patrol gong c can be saved. In the implementation of the present invention, the edge of the concave arc ci at the position of the second lug 3 4 1 1 of the light shielding tape can be further set into a fibrous c 2 , thereby further emitting the light source of the ear 3 411. The obvious process of reducing the brightness and darkness: the body light module 3 can output a uniform and high-luminance light source to improve the overall light-emitting efficiency. ^5285 In summary, the present invention is characterized in that a light-shielding #C is applied around the diffusion film 3 41, and the light-shielding band is continued to form a concave arc cl at the lug 3 4 11 , and < The edge of c丄 is set to weave. 2, not only is the structure simple and can effectively make the backlight module 3 turn out the uniform and high-luminance light source, in order to improve the overall light-emitting efficiency, and has the characteristics of _ sex and progress, and the New Zealand issued a statement The detailed review of the review committee, 4 grants the patent for the approval of the patent.
