Taking the backlight module used in the LCD as an example, the cost structure of the off-zero component is: 37.9% of the role of the brightness enhancement layer, about 4.4% of the diffusion layer of the diffusion layer, and about 4.4% of the lamp. 18.4%, the light guide plate accounts for about 20.8%. From the cost structure of these key components, if the wire (4) towel can be simplified or reduced, the cost of manufacturing the liquid crystal display device can be reduced. _ is to feed the Wei film, it can get better benefits. In addition, the well-known Ling lens will gather through the beam and increase the party's effect on evenly dispersing light is not very satisfactory, in general, the industry will Some people have designed and expanded under the lens. However, in addition to increasing the component cost, the effect is also limited. To improve this effect, please refer to the schematic diagram of the optical film of the conventional technology. - The implementation of the Patent Application No. _442 of the Republic of China (Fig. 3 in the patent) relates to a concentrating sheet 1 聚 having a brightening effect of the concentrating layer 12, under the concentrating layer 12 Is a substrate 11 'the other side of the substrate 11 contains A diffusion M326173 film 13' having a concave or convex roughness structure is used as a concentrating sheet 1 in a liquid crystal display. It is understood from the teachings in the drawing that the concave or convex roughness structure is the surface layer of the diffusion film 13, The particles 132 of different sizes are laterally arranged therein, and the particles 13〇2 protrude from the surface layer of the diffusion film 13 to make the surface of the diffusion film 13 thick and convex. However, this prior art process is more troublesome and requires more components. Therefore, the production cost is higher' and it is assisted by the single layer of particles 13〇2, although some optical interfaces are added, but the effect is still limited. 本. The purpose of this creative agency is to provide The optical film can achieve better two = ^ line, increase brightness, and anti-glare in the county at a lower manufacturing cost, so as to improve the above-mentioned problem [new content] and make it available in the back-side group of Can brighten up to the standard f Wei _ cost, one through = _: bright - = also contains a transparent medium and a number of scattering Hai Xuan Zheng Guangming ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί The county plate is relatively bright The other surface of the sub-figure f is a embossed gambling structure, and the irregular shape is dispersed in the transparent medium.

[Embodiment] Please refer to FIG. 2 and FIG. 2 is a schematic diagram of the optical film 30 of the present invention. The present invention is directed to an optical film 30 that further includes a vapor-permeable layer, 32, a party layer 34, and a diffusion layer. The diffusion layer 36 further includes a transparent medium 3602 of a plurality of scattering particles 3604. The translucent substrate 32 is a light transmissive plate. The brightness enhancement layer 34 is disposed on one surface of the moon-permeable substrate 32, wherein the brightness enhancement layer can be composed of a plurality of microstructures, the fine structure can be Wei, Philip lens and lens, or a cylindrical lens. microstructure. The diffusion layer 36 is disposed on the other surface of the transparent substrate 32 with respect to the brightness enhancing layer 34. The transparent medium 3602 is directly disposed on the other surface of the transparent substrate 32 relative to the thickening layer 34. The surface of the transparent medium is a concave and convex rough structure 3_, and the scattering particles are dispersed in an irregular shape in the transparent medium. In the leg, the diffusion layer 36 is composed of a turning medium 36G2 and scattering particles 3604 therein. 7 M326173 In contrast to the conventional technique, the rough surface of the present diffusion layer 36 is formed by the surface of the media, and the non-scattering particles are finely convex, so that more optical interfaces can be formed. Further, please refer to the top view of the three layers of the creation of the diffusion layer 36. In the top view of Fig. 2, there are many scattered particles 36〇4 scattered in the transparent medium 36G2, such scattered scattered particles· '· ^ into the silk interface 36G4A, the domain is smaller than the transparent medium to win the thickness of the scattering particles _, easy to up and down (on the optical path) overlap the negative optical interface # #, these optical interfaces will cause Light is refracted, so it has a better diffusion effect than conventional techniques. Further, the 'party layer 34, the transparent substrate 32, and the diffusion layer 36 may be of the same material. Moreover, the brightness enhancing layer 34, the transparent substrate 32, and the diffusion layer 6 can be made into a modular optical 3Q tree, and the brightness enhancing layer 34, the transparent plate 32, and the diffusion layer% For the same material, the temple is more conducive to simplifying the process and saving components, but more convenient to integrate (4) into a modular optical film 30 components. , ', / Hantu II is to turn the surface of the substrate 32 adjacent to the brightening layer 34 as the light-emitting surface 42, but the surface of the near-diffusion layer 36 is an example of the light-incident surface 4〇, this can also be as shown in Figure 4. Fig. 4 is an alternative example of the optical path of the present optical film 30. As shown in FIG. 4 , the surface of the transparent substrate 32 adjacent to the brightness enhancing layer 34 is a light incident surface 4 , and the surface of the transparent substrate 32 adjacent to the diffusion layer is a light emitting surface 42 , which can also be utilized as an industry. . It is to be noted that the method of disposing the transparent medium 3602 on the surface of the transparent substrate 32 can be accomplished by various methods such as coating, pad printing, hot pressing, transfer, spraying, fogging, and ejection. The scattering particles 36〇4 are distributed in the transparent medium 36〇2, or can be fixed and moved by other adjustable micro-locks. The transparent medium _, the scattering particles make the material, To %, H bright layer %, transparent substrate 32 material f, can also use PET, = 4, or _ material 'as mentioned above, even ": two:: wide dispersion layer 36 can use the same - material, (four) = The opticals mentioned are 3G. This creation can still provide the same technical examples. Please refer to _5 to Figure 7. The optical slices 30" have the same technical features as the above, but the transparent substrates with different shapes are the same. = layer 34, diffusion layer 36 combination structure, _ into the effect and excellent, please refer to Figure 8 and Figure 9, Figure 8 is another embodiment of the present creation, Figure IX is a schematic diagram of this real_. In this implementation, in addition to the spirit of the same technical features described above, a further diffusion concentrating microstructure 38 is added to the surface of the brightness enhancing layer 34, and the diffusing concentrating microstructure 38 has a wavy outer surface. The radius of curvature ranges from 5 fronts to iGG/zm, and the underlying brightening layer 34 is a different medium. Therefore, in addition to enhancing the diffusion effect of 0, it also has a concentrating effect. The underlying brightening layer 34 has a curved surface with a large radius of curvature (〇·〇5 awake~30匪), and the curved surface has a diffusion effect in addition to the original condensing effect. M326173 The body f τ class _ can also be combined with other aforementioned components. The ttf drop film (9) can be used in the same material or different materials as the other components. 〗 u The philosopher uses the optical film 30, the port 22, the transparent substrate 32, and the expanded layer 36 in the backlight module to form the optical film 30. To achieve uniform light, increase brightness, and anti-glare. Step-by-step, fine transparent medium _ surface concave five; ~ 纟 # structure 36·, and in the transparent medium _2 towel in an irregular shape scattered scatterer 36 〇 4, can achieve a better uniformization effect. The hfL is more clearly described in the specific example of the above-mentioned secrets, and it is more clear that the creation and the spirit of the present invention are implemented in the same way. On the contrary, it is hoped that the various changes and phases will be arranged within the scope of the patent scope of the application.
