显示面板 220可为液晶显示面板， 显示面板 220上设置有多个左眼图像 像素 222与多个右眼图像像素 223 , 左眼图像像素 222与右眼图像像素 223 交替设置。 左眼图像像素 222适于提供左眼图像， 右眼图像像素 223适于提 供右眼图像。
反射镜 230与视差屏障 250分别位于反射片 240的两相对侧，反射镜 230 适于透过背光模组 210的出射光线， 且反射与所述出射光线的行进方向相反 的光线。 反射镜 230可为介电反射膜或高反射金属膜， 且介电反射膜或高反 射金属膜上形成有多个开口， 以允许背光模组 210的出射光线透过， 其中， 介电反射膜可为由氧化铟锡与二氧化钛制成的薄膜， 高反射金属膜可为金属 铝或银钛合金制成的薄膜。
反射片 240为纵向栅栏状，其靠近显示面板 220的表面为若干反射面 242, 每一反射面 242上开设有一个 V型槽 243 , V型槽 243为微型结构， 其具有 相互垂直的第一内表面 243a与第二内表面 243b。反射片 240可由聚丙烯材料 及添加在聚丙烯材料中的多个反射粒子制成， 这些反射粒子的材料可为二氧 化钛或硫酸钡， 如此， 反射片 240具有较佳的反射性能。 当然， 反射片 240 的材质并不以此为限， 其还可由其他合适的具有反射性能的材料制成。
视差屏障 250包括若干遮光部 252, 相邻的遮光部 252间隔设置而形成 若干透光部 253 ,遮光部 252与透光部 253交替设置。反射片 240配置于视差 屏障 250的靠近反射镜 230的一侧， 反射片 240包括反射面 242和与反射面 242相对的背面（图未标）， 反射面 242相对于背面更靠近反射镜 230, 且反 射面 242的位置及数量对应于遮光部 252。透光部 253控制来自显示面板 220 的光线的行进方向， 让用户的左眼 262接收由左眼图像像素 222提供的左眼 图像， 让用户的右眼 263接收由右眼图像像素 223提供的右眼图像， 人眼看 到左眼图像与右眼图像会产生视差而达成立体显示效果。
工作时， 背光模组 210提供背光照亮显示面板 220, 来自显示面板 220 各像素的光线透过反射镜 230而射向视差屏障 250, 其中， 部分光线， 例如 图 3所示的光线 L1 , 透过透光部 253而进入用户的左眼 262或右眼 263 , 而 另一部分射向遮光部 252 的光线由反射片 240 的反射面 242反射至反射镜 230, 并由反射镜 230再次反射而重新定向。 具体而言， 来自显示面板 220的 任意一像素 （如图 3所示， 以任意一右眼图像像素 223为例）并射向视差屏 障 250的遮光部 252的出射光线 L照射于反射片 240的 V型槽 243的第一内 表面 243a, 出射光线 L经过第一内表面 243a反射并经过一定的光程 D而照 射至第二内表面 243b, 因为第二内表面 243b与第一内表面 243a相互垂直， 根据光线的反射原理， 经第二内表面 243b反射的返回光线 L， 与出射光线 L 平行。 又因为反射面 242为微型结构， 出射光线 L由第一内表面 243a反射至 第二内表面 243b的光程 D较小， 所以返回光线 L， 与出射光线 L基本重合。
换言之， 经过反射片 240反射作用后， 来自任意一像素并射向视差屏障
250的遮光部 252的出射光线 L仍能返回至所述像素的位置， 可避免与其他 像素的出射光线发生颜色干扰， 提升显示画面的品质。 显示面板 220上设有 反射镜 230, 反射镜 230可将返回光线 L， 反射， 如此可以避免任意一像素的 光线损失， 使左眼图像像素 222与右眼图像像素 223的出射光线更多地经过 视差屏障 250的透光部 253而进入用户的眼睛。
需要注意的是， 反射片 240与视差屏障 250可一体成型。
图 4为本发明第二实施例的立体显示装置的结构示意图。 请参见图 4, 本发明第二实施例的立体显示装置 200，与第一实施例的立体显示装置 200相 似， 不同之处为： 每一反射面 242'开设有两个 V型槽 243' , V型槽 243'具 有相互垂直的第一内表面 243a，与第二内表面 243b，。 本发明并不限定 V型槽 243'的数量， 可依据视差屏障 250'的遮光部 252'尺寸大小来确定 V型槽 243' 的数量， 设置两个以上的 V型槽 243，， 且尽量使 V型槽 243，的结构微型化， 而使得经 V型槽 243，的表面反射的光线可以沿原路返回， 从而避免各像素的 出射光线发生颜色干扰， 提升立体显示装置的画面品质。
图 5为本发明第三实施例的立体显示装置的结构示意图。 请参见图 5 , 本发明第三实施例的立体显示装置 300与第一实施例的立体显示装置 200相 似， 不同之处为： 反射镜 330配置于背光模组 310与显示面板 320之间。 反 射片 340靠近显示面板 320的一侧为反射面 342,反射面 342的结构与第一实 施例中的反射面 242的结构完全相同， 在此不再作重复说明。
工作时， 背光模组 310的出射光线透过反射镜 330而为显示面板 320提 供背光， 来自显示面板 320各像素的光线射向视差屏障 350, 部分光线穿过 透光部 353而进入用户的左右眼 362、 363 , 而另一部分射向遮光部 352的光 线由反射片 340的反射面 342反射。 因为反射面 342包括两个相互垂直的表 面， 所以， 经过反射片 340反射作用后， 来自任意一像素并射向视差屏障 350 的遮光部 352的出射光线仍能返回至所述像素的位置， 可避免与其他像素的 出射光线发生颜色干扰。 同时， 由反射片 340反射而进入显示面板 320的光 线再次由反射镜 330反射， 而进一步为显示面板 320提供背光， 使更多的光 线能够得到利用， 提升光线利用率， 进而增加显示画面的亮度。 此外， 反射 镜 330还可反射外界光线而为显示面板 320提供背光，增加显示画面的亮度， 节省电能， 同时有利于减少立体显示装置 300的重量。
需要注意的是， 在本实施例中， 每一反射面 342上开设有一个 V型槽， 在另一实施例中， 可依据视差屏障 350的遮光部 352尺寸大小来确定 V型槽 343的数量， 设置两个或两个以上的 V型槽 343 , 且尽量使 V型槽 343的结 构微型化， 而使得经 V型槽 343的表面反射的光线可以沿原路返回， 从而避 免各像素的出射光线发生颜色干扰。
图 6为本发明第四实施例的立体显示装置的结构示意图。 请参见图 6 , 本发明第四实施例的立体显示装置 400与第三实施例的立体显示装置 300相 似， 不同之处为： 立体显示装置 400的反射片 440的反射面 442为平面。
工作时， 背光模组 410的出射光线透过反射镜 430而为显示面板 420提 供背光， 来自显示面板 420各像素的光线射向视差屏障 450 , 部分光线穿过 透光部 453而进入用户的左右眼 462、 463 , 而另一部分射向遮光部 452的光 线直接由反射片 440的反射面 442反射。 经过反射面 442反射而进入显示面 板 420的光线再次由反射镜 430反射， 而进一步为显示面板 420提供背光， 从而增加显示画面的亮度。 此外， 反射镜 430还可反射外界光线而为显示面 板 420提供背光。
在另一实施例中， 反射镜 430也可设置于显示面板 420与反射片 440之 间。
图 7为本发明第五实施例的立体显示装置的反射片的结构示意图。 在此 必须说明的是， 为了方便说明起见， 第五实施例的立体显示装置省略了对背 光模组、 反射镜、 显示面板及视差屏障的绘示。 请参见图 7 , 本发明第五实 施例的立体显示装置与第三实施例的立体显示装置 300相似， 不同之处为： 每一反射面 542上开设有若干三棱锥状凹槽 543 , 三棱锥状凹槽 543具有三 个相互垂直的内表面 543a、 543b, 543c。 三棱锥状凹槽 543为微型结构， 可 依据实际需求， 确定三棱锥状凹槽 543的大小及排布方式。 工作时， 由于三 棱锥状凹槽 543具有三个相互垂直的内表面 543a、 543b, 543c, 才艮据光线的 反射原理， 来自显示面板的光线经过反射片 540的三棱锥状凹槽 543的内表 面 543a、 543b, 543c反射后可大致沿原路返回， 同样可以避免各像素的出射 光线发生颜色干扰。
需要注意的是， 图 7中反射片 540示意性地绘示四个反射面 542 , 但反 射面 542的数量并不以此为限， 可依据实际需要任意设定。 图 7所示的反射 片 540也可用于第一实施例的立体显示装置 200的结构中， 即反射镜位于显 示面板与反射片之间。 综上所述， 本发明的立体显示装置至少具有以下的优 点：
1.视差屏障的靠近显示面板的一侧设有反射片， 来自显示面板并射向视 差屏障的遮光部的光线由反射片反射， 经反射片反射后的光线再由反射镜反 射， 从而让更多的光线进入用户的左右眼， 提升显示画面的亮度。 同时， 当 亮度需求为一定值时， 本发明的立体显示装置重量较轻。
2.在本发明的一实施例中， 反射片的反射面上开设有若干 V型槽或若干 三棱锥状槽， 每一 V型槽具有两个相互垂直的内表面， 每一锥状槽具有三个 相互垂直的内表面， V型槽或三棱锥状槽均为微型结构， 所述的反射面可将 射向视差屏障的遮光部的光线反射并使其大致沿原路返回， 而避免了各像素 间颜色的干扰， 有利于提升显示画面的品质。
3.在本发明的一实施例中， 反射镜配置于背光模组与显示面板之间， 反 为显示面板提供背光， 增加显示画面的亮度， 节省电能， 同时有利于减少立 体显示装置的重量。
以上所述， 仅是本发明的实施例而已， 并非对本发明作任何形式上的限 制， 虽然本发明已以实施例揭露如上， 然而并非用以限定本发明， 任何熟悉 本专业的技术人员， 在不脱离本发明技术方案范围内， 当可利用上述揭示的 技术内容作出些许更动或修饰为等同变化的等效实施例， 但凡是未脱离本发 等同变化与修饰， 均仍属于本发明技术方案的范围内。 工业实用性 在本发明的立体显示装置中， 视差屏障的靠近显示面板的一侧设有反射 片， 来自显示面板并射向视差屏障的遮光部的光线由反射片反射， 经反射片 反射后的光线再由反射镜反射， 从而让更多的光线进入用户的左右眼， 提升 显示画面的亮度。 同时， 当亮度需求为一定值时， 本发明的立体显示装置重 量较轻。
