Description

立体显示装置 技术领域
本发明涉及一种立体显示装置， 属于液晶显示技术领域。 背景技术
随着三维立体技术在个人娱乐及数字家庭领域的广泛应用， 三维集成成像 (Three dimensional Integral Imaging, 3DII)技术作为立体显 技术的一一种， 在:三维 电视、 立体投影显示、 医学— Ξ:维成像、 虚拟和增强现实等领域具有广阔的应用前 景。 Ξ:维显示能够呈现物体的深度信息。 在同样的屏幕大小和视角的情况下， 人 在观看 Ξ:维电视时， 感觉整个图像的质量、 亮度感、 深度感以及逼真程度都要比 二维电视强得多。
三维立体显示技术分为眼镜式立体显示技术和裸眼式立体显示技术。 前者需 要佩戴特殊眼镜才能观看到三维效果， 后者不需要佩戴任何眼镜即可观看到≡维 效果， 也称为自由立体显示技术。 于普通消费者来说， 每幅眼镜的价格也不菲。 因此， 从消费者的长远利益上考虑， 对于裸眼式三维立体显示技术的研究显得尤 为重要。
真实立体显示技术是指不需利用人眼双目视差原理的 3D 显示， 集成成像 (Integral imaging)即是此类显示技术之一。目前见到的大部分立体显示都是利用双 目视差， 长时间观看会造成视觉疲劳或适应不良等问题。 集成成像可提供 360度 的视角，在视角范围内可以提供近乎连续变化的视差，而旦不需要配戴辅助跟镜。
：三维集成成像技术， 又称为—三维集成摄影技术 (3D Integral Photography, 3D P)，作为一种全真:三维光学成像的新方法已成为多视差立体成像与显示领域的 研究热点。 三维集成成像技术具有不需要特殊眼镜和相千光源、 全视差、 连续视 点， 且能与现有高清晰度电视制式有很好的兼容性等优点。
传统的三维集成成像 (Conventional Integral Imaging, CII)系统的结构包括记录 徵透镜阵列、 中继透镜、 电荷耦合器件 (CCD)、 显示微透镜阵列、 显示器件等。 一般情况下， 重构图像的分辨率是判断三维集成成像系统性能的重要指标之一， 而重构图像的分辨率是受系统的各个参数影响的， 比如透镜阵列的孔径大小和占 空比， 电荷耦合器件及显示器件的分辨率等。 ffl于微单元图像必须要有足够的分 辨率才能被检测及显示出来， 所以记录及显示器件的像素大小成为决定重构:三维 图像分辨率的重要因素。
集成成像的原理如图 : 所示， 记录过程是借由微透镜阵列 1对空间场景 （即 目标 2) 进行采集， 微透镜阵列 i 从不同方向角度记录一部分场景 （即目标 2) 的 ¾息，每个透镜对应生成一幅不同方位视角的元素图像 3 (位于图像传感器 4)。 经过 3D数据处理得到经过数据性处理的 3D数据 6。 重现 3D图像只需要具备同 样参数的透镜阵列 Γ ,根据光路—可逆原理即可重构元素图像 3' (位于显示面板 5 )， 得到连续视差的 3D图像 2'。
参照图 2。 集成成像的观察区域定义为观察者能在此区域内看到一个具有完 整分辨率的图像， 观察区域的大小取决于距显示器特定距离的横截面宽度 D, 及 透镜阵列 Γ的完整出射角。
f p '、
2g .i 其中 p是透镜的直径、 g是透镜阵列和元素图像的间距， 集成成像的视角即 由此决定。
图 2显示了观察区域 7(Viewing zoiie)的定义，若观察者处于观察区域 7之夕卜， 例如处于区域 8中， 会看到畸变旦跳动的 3D重建图像 (image flip), 因为从元素 图像 3'发出的光线是透过透镜阵列 Γ上原本对应透镜的相邻透镜发出的。
对此， 本发明提出一种新的架构可用于增加集成成像视角， 避免看到畸变影 像。 发明内容
图 2显示了观察区域 (Viewing zone)?的定义，若观察者处于观察区域 7之外， 例如处于区域 8中， 会看到畸变旦跳动的 3D重建图像 (image flip), 因为从元素 图像 3'发出的:光线是透过透镜阵列 Γ上原本对应透镜的相邻透镜发出的。

下面将参照爾图来详细地介绍本发明。
图 3显示了根据本发明的立体成像装置的奇数行全黑的状态； 图 4显示了根 据本发明的立体成像装置的偶数行全黑的状态。
参照图 3和图 4, 本发明提出了一种立体成像装置。 其包括用于显示元素图 像的液晶显示器 11 和透镜阵列 12， 液晶显示器 i i所发出的光线经过透镜阵列 12射出。
其中， 在液晶显示器 11和透镜阵列 12之间布置有能够影响光线偏振状态的 第一器件 13和相位延迟单元， 来自液晶显示器 11 的光线相继经过第一器件 13 和相位延迟单元而进入透镜陈列 12。 最终进入显示区域被观察者所观察到。
第一器件 13例如为扭曲向列型液晶盒。 参照图 3和图 4, 第一器件】3构造 成当对其施加电压时，其不影响经过其的光线的偏振状态，当不对其施加电压时， 其使得经过其的光线的偏振方向呈 90度旋转。 第 ·器件 13的刷新率为 120Hz。
参照图 3， 为了解决现有技术中的在观察者移动之后观察到了进入相邻透镜 的光线的问题， 本发明的立体显示装置进行如下布置。
第一器件 13(例如 TN液晶盒)和相位延迟单元协作能够使得液晶显示器 11的 液晶像素的奇数行所对应的显示画面正常， 而偶数行所对应的显示画面全黑， 并 且第一器件 13和相位延迟单元协作能够使得液晶显示器 i l的液晶像素的偶数行 所对应的显示画面正常， 而奇数行所对应的显示画面全黑。
这又通过如 T结构设†来完成。 参照图 3和图 4, 相位延迟单元包括相位延迟薄膜 14, 相位延迟薄膜 14在与 奇数行的液晶像素相对应的位置处不对通过的光线造成影响， 在与偶数行的液晶 像素相对应的位置处对通过的光线造成半波长的相位延迟以使其偏振方向旋转 90度。
相位延迟薄膜 14的晶体轴向与液晶显示器 11所发出的光线的偏振方向呈 45 度角。
相位延迟单元还包括位于相位延迟薄膜 14的朝向透镜阵列 12—侧上的偏振 片 15。偏振片 15仅能够通过偏振方向与液晶显示器 11所发出的光线的偏振方向 垂直的光线。
参照图 3 , 在图 3所示的状态中， 液晶显示器 1所发出的光线经过施加了电 压的扭曲向列型液晶盒 13 , 其不受影响地通过并到达相位延迟薄膜 〗4。 相位延 迟薄膜 14在与奇数行的液晶像素相对应的位置处不对通过的光线造成影响， 在 与偶数行的液晶像素相对应的位置处对通过的光线造成半波长的相位延迟以使 其偏振方向旋转 90度。 而偏振片 15仅能够通过偏振方向与液晶显示器 1 1所发 出的光线的偏振方向垂直的光线。 因此液晶显示器 i l 的液晶像素的偶数行所对 应的显示画面正常， 而奇数行所对应的显示画面全黑， 解决了现有技术中光线偏 移到相邻透镜中的 题。
参照图 4, 在图 4所示的状态中， 液晶显示器 11所发出的光线经过未施加电 压的扭曲向列型液晶盒 13 , 其偏振方向偏转了 90度后到达相位延迟薄膜 14。 相 位延迟薄膜 14在与奇数行的液晶像素相对应的位置处不对通过的光线造成影响， 在与偶数行的液晶像素相对应的位置处对通过的光线造成半波长的相位延迟以 使其偏振方向旋转 90度。 而偏振; t 15仅能够通过偏振方向与液晶显示器 1 1所 发出的光线的偏振方向垂直的光线。 因此液晶显示器 〗1 的液晶像素的奇数行所 对应的显示画面正常， 而偶数行所对应的显示画面全黑， 解决了现有技术中光线 偏移到相邻透镜中的问题。
参照图 5， 之后通过电压刷新扭曲向列型液晶盒 13， 显示画面在状态 1和状 态 2之间不断转换， 利用观察者的视觉暂留可以使其看到完整的全像素画面。 扭 曲向列型液晶盒 13的刷新频率可以为 120Hz。
根据本发明的装置的优势在于， 搭配高刷新率的扭曲向列型液晶盒， 可以让 观察者看到具有完整分辨率的影像。同时整合了空间多任务 (通过图案化的半波长 相位延迟薄膜 (half wave plate pattern Hoarder))和时间多任务 (通过高刷新率的扭曲 向列型液晶盒)的设想，在保持完整分辨率的同时，也能增加 维立体显示的视角。
然而，在本发明的其它变体中，也可以是相位延迟单元包括相位延迟薄膜 14, 相位延迟薄膜 14在与偶数行的液晶像素相对应的位置处不对通过的光线造成影 响， 在与奇数行的液晶像素相对应的位置处对光线造成半波长的相位延迟以使其 偏振方向旋转 90度， ϋ偏振 j† 15仅能够通过偏振方向与液晶显示器 i l所发出 的光线偏振方向垂直的光线。
第一器件 13也可以别的方式影响光线的偏振，倒如在施加电压的情况下造成 偏振角度 90度偏转， 而在不施加电压的情况 T不影响光线的传播。
相位延迟薄膜 14的图案， 以及偏振片】5的布置方向也可以有其它的布置， 只要能够达到上述奇数行或偶数行的全黑显示效果即可。
虽然已经参考优选实施例对本发明进行了描述， 但在不脱离本发明的范围的 情况下， 可以对其进行各种改进并且可以用等效物替换其中的部件。 本发明并不 局限于文中公幵的特定实施例， 而是包括落入权利要求的范圈内的所有技术方
