本发明的较佳实施方式 Preferred embodiment of the invention
图 1是本发明第一实施例的立体眼镜的示意图。 图 2是图 1所示的立体 目艮镜沿 11-11， 沿线剖开的剖面示意图。 请参见图 1与图 2, 本发明第一实施例 的立体眼镜 10包括左眼部 12及右眼部 14。 左目艮部 12与右眼部 14相连接， 并且分别具有本体与环境光过滤膜。 本实施例中， 左眼部 12与右眼部 14的 结构相似， 为避免重复描述， 以下将以左眼部 12为例做说明。 左眼部 12包 括本体 122与环境光过滤膜 124。环境光过滤膜 124设在本体 122上，其用于 防止环境光线通过左眼部 12与右眼部 14射入观看者的眼睛， 进而提高观看 者观看影像的视觉效果。  1 is a schematic view of a stereoscopic eyeglass according to a first embodiment of the present invention. Figure 2 is a cross-sectional view of the stereoscopic frog mirror shown in Figure 1 taken along line 11-11. Referring to Figures 1 and 2, the stereoscopic eyewear 10 of the first embodiment of the present invention includes a left eye portion 12 and a right eye portion 14. The left eyelid portion 12 is connected to the right eye portion 14, and has a body and an ambient light filter film, respectively. In the present embodiment, the structure of the left eye portion 12 and the right eye portion 14 are similar. To avoid repeated description, the left eye portion 12 will be described below as an example. The left eye portion 12 includes a body 122 and an ambient light filtering film 124. The ambient light filter film 124 is disposed on the body 122 for preventing ambient light from entering the viewer's eyes through the left eye portion 12 and the right eye portion 14, thereby improving the visual effect of the viewer viewing the image.
在本实施例中， 左眼部 12还可包括外框 126, 环境光过滤膜 124设在本 体 122的外侧表面 （亦即环境光过滤膜 124设在本体 122的入光侧 ) , 并且 本体 122与环境光过滤膜 124是设在外框 126内由外框 126所承载。 可以理 解， 本发明并不以包含外框 126为限， 在其他实施例中， 例如无框眼镜， 左 目艮部 12与右眼部 14也可不包含外框 126。环境光过滤膜 124可由透明树脂材 料或透明氧化物形成， 透明氧化物例如为硅、 铝、 辞、 锑、 镍、 铟、 锆或锡 的氧化物。  In this embodiment, the left eye portion 12 may further include an outer frame 126, and the ambient light filtering film 124 is disposed on the outer surface of the body 122 (that is, the ambient light filtering film 124 is disposed on the light incident side of the body 122), and the body 122 The ambient light filter film 124 is disposed within the outer frame 126 and carried by the outer frame 126. It is to be understood that the present invention is not limited to the inclusion of the outer frame 126. In other embodiments, such as rimless glasses, the left eyelid portion 12 and the right eye portion 14 may not include the outer frame 126. The ambient light filter film 124 may be formed of a transparent resin material such as silicon, aluminum, rhodium, ruthenium, nickel, indium, zirconium or tin oxide or a transparent oxide.
环境光过滤膜 124可为反射膜， 其可通过沉积或涂布的方式形成。 由于 环境光线的入射角通常都大于影像光线的入射角， 因此环境光过滤膜 124可 适于反射入射角大于预定角度的环境光线。 请参见图 2, 环境光过滤膜 124 可包含第一折射率层 1242与第二折射率层 1244。 第一折射率层 1242靠近本 体 122的外侧表面， 第二折射率层 1244位于第一折射率层 1242的上方， 即 第一折射率层 1242位于本体 122与第二折射率层 1244之间。 第一折射率层 1242与第二折射率层 1244之间形成第一界面 1243 ,第二折射率层 1244具有 入光面 1245。 通过设置第一折射率层 1242与第二折射率层 1244折射率， 可 使光线在入光面 1245发生全反射的临界角大于在第一界面 1243发生全反射 的临界角。例如，光线 Ll L2, L3分别以入射角 Θ 1 θ 2, θ 3入射入光面 1245, 其中， θ ^ θ ^ θ 光线 L2, L3为环境光， 光线 为影像光线， θ 2为光线 入射临界角 Θ c (即入射角度大于或等于 Θ c的可见光不会进入左眼部 12的本 体 122, 入射角度小于 6 C的可见光则可进入左目艮部 12的本体 122 )。 详细来 说， 光线 L2, L3在第一界面 1243会发生全反射而从入光面 1245射出左眼部 12, 从而不会进入观看者的眼睛眼； 光线 则可通过第一界面 1243进入本 体 122并可到达观看者的眼睛。 The ambient light filter film 124 can be a reflective film that can be formed by deposition or coating. Since the angle of incidence of the ambient light is generally greater than the angle of incidence of the image light, the ambient light filter film 124 can be adapted to reflect ambient light having an angle of incidence greater than a predetermined angle. Referring to FIG. 2, the ambient light filter film 124 may include a first refractive index layer 1242 and a second refractive index layer 1244. The first refractive index layer 1242 is adjacent to the outer surface of the body 122, and the second refractive index layer 1244 is located above the first refractive index layer 1242, ie The first refractive index layer 1242 is located between the body 122 and the second refractive index layer 1244. A first interface 1243 is formed between the first refractive index layer 1242 and the second refractive index layer 1244, and the second refractive index layer 1244 has a light incident surface 1245. By setting the refractive indices of the first refractive index layer 1242 and the second refractive index layer 1244, the critical angle at which the light is totally reflected on the light incident surface 1245 is greater than the critical angle at which the total reflection at the first interface 1243 occurs. For example, the light rays L l L 2 , L 3 are incident on the light surface 1245 at an incident angle Θ 1 θ 2 , θ 3 , respectively, wherein θ ^ θ ^ θ light L 2 , L 3 is ambient light, and the light is image light, θ 2 is the incident angle 光线c of the light incident (ie, the visible light having an incident angle greater than or equal to Θ c does not enter the body 122 of the left eye portion 12, and the visible light having an incident angle of less than 6 C may enter the body 122 of the left target portion 12). In detail, the light rays L 2 , L 3 are totally reflected at the first interface 1243 and the left eye portion 12 is emitted from the light incident surface 1245 so as not to enter the eyes of the viewer; the light can enter through the first interface 1243. The body 122 can reach the viewer's eyes.
光线入射临界角 e c设计的大小可依据屏幕的大小、观看者距离屏幕的远 近等因数来确定， 而藉由配置第一折射率层 1242与第二折射率层 1244的折 射率， 可调节光线入射临界角 6 C的大小， 从而可满足不同的设计要求。 The size of the light incident critical angle e c can be determined according to the size of the screen, the distance of the viewer from the screen, and the like, and the light can be adjusted by configuring the refractive indices of the first refractive index layer 1242 and the second refractive index layer 1244. The incident critical angle is 6 C , which can meet different design requirements.
上述立体眼镜 10包括环境光过滤膜 124, 环境光过滤膜 124可过滤进入 左眼部 12与右眼部 14的入射角大于预定角度的环境光线， 从而可使环境光 减少甚至避免环境光线进入观看者的眼睛， 进而提高观看者观看影像的视觉 效果。具体在本实施例中，入射角大于或等于光线入射临界角 e c的环境光线 会被环境光过滤膜 124反射出去，而入射角小于光线入射临界角 e c的环境光 线则会通过环境光过滤膜 124进入本体 122并可到达观看者的眼睛， 因此有 利于提高观看者观看影像的视觉效果。 The stereoscopic glasses 10 include an ambient light filtering film 124. The ambient light filtering film 124 can filter ambient light entering the left eye portion 12 and the right eye portion 14 by an angle greater than a predetermined angle, thereby reducing ambient light or even preventing ambient light from entering the viewing. The eyes of the person, thereby enhancing the visual effect of the viewer viewing the image. Specifically, in this embodiment, the ambient light having an incident angle greater than or equal to the critical angle e c of the light incident is reflected by the ambient light filter film 124, and the ambient light having an incident angle smaller than the critical angle e c of the light incident is filtered by the ambient light. The film 124 enters the body 122 and can reach the viewer's eyes, thereby facilitating the visual effect of the viewer viewing the image.
图 3是本发明第二实施例的立体眼镜的剖面示意图。 第二实施例的立体 眼镜 20与立体眼镜 10相似， 其不同点在于立体眼镜 20的环境光过滤膜 224 为导光膜。 以立体眼镜 20的左眼部 22为例做说明： 环境光过滤膜 224形成 于左眼部 22的本体 222的外侧面， 其可由多层折射率不同的透光层构成； 在 环境光过滤膜 224的两端，外框 226上设有开口 2262用于使环境光线从左眼 部 22 两边射出而不进入观看者的眼睛。 详细来说， 通过设置环境光过滤膜 224 各层的折射率， 以使入射角度大于或等于预定角度的光线（环境光）被 导引到环境光过滤膜 224两端的位置（亦即左眼部 22的边缘处） 出射， 从而 不会进入观看者的眼睛； 而入射角度小于预定角度的光线（影像光线）则可 通过环境光过滤膜 224进入本体 222并到达观看者的眼睛。 更详细地， 例如 环境光过滤膜 224可以包括第一折射率层与第二折射率层， 第一折射率层位 于本体 222与第二折射率层之间， 第二折射率层远离本体 222一侧的表面为 入光面， 第一折射率层与第二折射率层之间具有第一界面， 光线在入光面发 生全反射的临界角小于或等于在第一界面发生全反射的临界角， 这样在第一 光过滤膜 224两端的位置出射， 但本发明并不以此为限。 3 is a schematic cross-sectional view of a stereoscopic eyeglasses according to a second embodiment of the present invention. The stereoscopic glasses 20 of the second embodiment are similar to the stereoscopic glasses 10 except that the ambient light filtering film 224 of the stereoscopic glasses 20 is a light guiding film. The left eye portion 22 of the stereoscopic glasses 20 is taken as an example for explanation: The ambient light filter film 224 is formed on the outer side surface of the body 222 of the left eye portion 22, and may be composed of a plurality of light transmissive layers having different refractive indices; At both ends of the 224, the outer frame 226 is provided with an opening 2262 for allowing ambient light to be emitted from both sides of the left eye portion 22 without entering the viewer's eyes. In detail, by setting the refractive index of each layer of the ambient light filter film 224, light rays (ambient light) having an incident angle greater than or equal to a predetermined angle are guided to the ends of the ambient light filter film 224 (ie, the left eye portion). Exit at the edge of 22) It does not enter the viewer's eyes; light (image light) with an incident angle less than a predetermined angle can enter the body 222 through the ambient light filtering film 224 and reach the viewer's eyes. In more detail, for example, the ambient light filter film 224 may include a first refractive index layer and a second refractive index layer, the first refractive index layer being located between the body 222 and the second refractive index layer, and the second refractive index layer being away from the body 222 The surface of the side is the light incident surface, and the first interface between the first refractive index layer and the second refractive index layer has a first interface, and the critical angle of total reflection of the light on the light incident surface is less than or equal to the critical angle of total reflection at the first interface. Thus, the light is emitted at the positions of both ends of the first light filtering film 224, but the invention is not limited thereto.
可以理解， 若立体眼镜 20为无框眼镜， 则环境光可直接从环境光过滤膜 224两端出射。  It can be understood that if the stereo glasses 20 are rimless glasses, the ambient light can be directly emitted from both ends of the ambient light filtering film 224.
