In the singularity of the general knowledge, the hardware manufacturer may use the _ noun to refer to the same component. This lang and subsequent applications The patent scope does not use the difference in name as the way to distinguish the components, but the difference in function of the components as the criterion for differentiation. The "contains" mentioned in the entire specification and subsequent requests are open-type slang, so the syllabus is "included but not limited to". Please refer to Fig. 1 'Fig. 1 is a schematic structural view of an embodiment of a brain of a composite light guiding structure. As shown in FIG. 1 , the light guide structure 100 includes a first light guide plate 11 , a second light guide plate 120 , and an optical microstructure ( optical micron structure) 13 , optical The structure of the microstructure 130 is placed between the first light guide plate no and the second light guide plate (10), and the material of the first light guide plate 110 is different from the material f of the second light guide plate 12G. When a domain enters the composite light guiding structure 100, the light can be transmitted outside the composite light guiding structure 100 through the optical microstructure 130. The composite light guiding structure 100 will be further described below. In this embodiment, the composite light guiding structure 丨00 is disposed in one of the button modules of the handheld device (for example, a mobile phone), and is used as a light guide plate. However, this is a limitation of the creation, The combined composite light guiding structure can be applied to any device that needs to guide the M342603 optical structure (for example, in the backlight module of the liquid crystal display). As described above, the material of the first light guide plate 110 is different from that of the second light guide plate 12, and in the composite light guide structure 1 of the embodiment, the material of the first light guide plate is soft. A flexible light guide material having a hardness of more than 45 and a tensile strength greater than 5·5*ι〇6 Pascal (pa). For example, the material of the first light guide plate 110 may be a 矽The oxygen compound (silic〇nec〇mp〇und), φ has a hardness of '6·7*106 Pascal. In the composite light guiding structure 100 of the embodiment, the material of the second light guiding plate 120 is a polycarbonate (PC) material, and the hardness and tensile strength are greater than that of the first light guiding plate 110. However, this It is not a limitation of the creation. For example, the material of the second light guide plate 120 only needs to be a material that does not adsorb the polyester reflective sheet, so it can also be a polyester (PET) material. . Since the composite light guiding structure 1 has a first light guide plate U0 ® of a silicon oxide compound and a second light guide plate 120 of a polycarbonate (polyester) material, when the composite light guiding structure 1 is used as a button mode When one of the light guide plates is used, the composite light guide structure 1 can be contacted with one of the polyester film reflectors on one side of the second light guide plate 120, so that the composite light guide The structure 100 can retain the advantages of using a silicon oxide compound as a light guide plate (for example, high luminance), and can also utilize the advantages that the polycarbonate (polyester) light guide plate and the poly-g reflective sheet do not adsorb each other to avoid the composite type. The light guiding structure! 〇〇 and the polyester reflective sheet produce an adsorption phenomenon. M342603 In addition, the thickness of the composite light guiding structure 100 is not more than 〇·3 mm (mm). In the embodiment, the thickness of the first light guiding plate no (the lithography compound light guiding plate) is only 0.15 to 0.2 mm. (mm), the desired brightness can be achieved; and the thickness of the second light guide plate (polycarbonate light guide plate) only needs to be 〇·〇5~〇·1 mm (mm), so as to avoid the composite light guide The structure 100 and the polyester reflective sheet produce an adsorption phenomenon. In addition, in the embodiment, the optical microstructure 13 is an optical reflective structure, and is composed of a plurality of optical reflecting units for reflecting the light incident on the composite light guiding gentleman structure 100. Said to avoid the phenomenon of total reflection in the composite $ light structure (10). Please note that in the above embodiment, the material of the first light guide plate 110 is a material of the light guide material. The second light guide plate is read through (4) for the polycarbonate material and the (ρο-b read, PC) material, however This is only used as an example. «The limitation of this creation. In other embodiments, the material of the composite light guide structure - the material of the first guide plate can be designed according to the design requirements. It is also an example of this creation. As can be seen from the description of the above, in comparison with the prior art, the light-conducting structure combined with the _ dissimilar material f state can be a miscellaneous axis of its own, so that the complex V is first learned.
