柱透镜组件和显示装置 技术领域
本发明涉及立体显示技术领域，具体地，涉及能够实现平面显 示与立体显示切换的柱透镜组件和包括该柱透镜组件的显示装置。
背景技术
人类通过左眼和右眼所看到的同一物体的细微差异来感知该物 体的深度，从而识别出该物体的立体图像。上述差异被称为视差。立 体显示技术就是通过人为的手段来制造观看者的左、右眼视差，给观 看者的左、右眼分别送去有视差的两幅图像，使大脑在获取了左、右 眼看到的有视差的两幅图像之后，产生真实的立体感觉。
为了满足不同用户的喜好(有些用户希望体验立体显示效果， 而有些用户则希望体验平面显示效果)，已经有一些显示装置中设置 了平面显示/立体显示切换机构，其可根据用户的选择使显示装置呈 现不同的显示效果。
现有技术中，能实现平面显示/立体显示切换的显示装置包括显 示面板和设置在显示面板出光面一侧的液晶光栅，平面显示时，液晶 光栅为透光面；立体显示时，液晶光栅为间隔设置的多个透光条纹与 多个遮光条纹，液晶光栅配合显示面板使用户左眼仅看到左眼图像， 右眼仅看到右眼图像，且左眼图像和右眼图像存在视差，从而实现立 体显示。虽然利用液晶光栅可实现平面显示/立体显示切换，但这种 包含液晶光栅的显示装置的结构复杂，成本较高，而且光源利用率低、 能耗高。
现有技术中也有利用透镜组件来实现平面显示/立体显示切换的 显示装置，这种透镜组件包括凹透镜和与之契合的凸透镜，凹透镜和 凸透镜均由双折射材料制成，凹透镜的其中一个折射率与凸透镜的其 中一个折射率大小相等，且对于某一特定的偏振方向的偏振光，凹透 镜表现为寻常光折射率，凸透镜表现为非寻常光折射率。为了实现平 面显示和立体显示之间的切换，该显示装置还需要配置一种可切换偏 振器，该可切换偏振器可以在通过光的第一偏振分量的的第一偏振模 式和通过光的第二偏振分量的第二偏振模式之间进行切换。这种包含 透镜组件的显示装置的结构也比较复杂、成本较高。
因此，如何利用简单的结构实现平面显示和立体显示之间的切 换成为本领域亟待解决的技术问题。

具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理 解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不 用于限制本发明。
如图1至图3以及图8至图10所示，作为本发明的一个方面， 提供一种柱透镜组件，其包括闭合罩10、柱透镜阵列20和用于储存 透明液体的储液槽30，柱透镜阵列20与闭合罩10之间形成填充腔 室50，该填充腔室50与储液槽30连通，储液槽30中的透明液体可 以在储液槽30和填充腔室50之间流动，并且可以充满填充腔室50， 储液槽30中的透明液体的折射率与柱透镜阵列20的折射率相同，闭 合罩10的顶部采用透明材料制成。
应当理解的是，此处所述的闭合罩的“顶”部对应使用过程中 朝向观看者的一侧。
本发明所提供的柱透镜组件可以设置在显示面板的上方，与显 示面板配合使用，并实现平面显示和立体显示之间的转换。
具体地，当需要平面显示时，储液槽30能够使其储存的透明液 体充满填充腔室50；当需要立体显示时，储液槽30能够使填充腔室 50内的透明液体至少部分地流回储液槽30。下文中将详细介绍平面 显示和立体显示切换的原理，这里先不赘述。
容易理解的是，所述透明液体是没有颜色的，并且光线可以透 过闭合罩10的顶部射入填充腔室50内。
在本发明中，对柱透镜阵列20的具体形式不做限定，只要柱透 镜阵列20可以对射入该柱透镜阵列20的光线进行折射，以改变光线 的传播方向并最终实现立体显示即可。例如，柱透镜阵列20可以包 括平行设置的多个凹透镜，或者，柱透镜阵列20可以包括平行设置 的多个凸透镜。应当理解的是，无论是凹透镜还是凸透镜，都应当是 柱状的。
在本发明所提供的具体实施方式中，柱透镜阵列20包括平行设 置的多个凸透镜(即，组成柱透镜阵列20的柱透镜20a均为凸透镜)， 该多个凸透镜的凸面朝向一致(均朝向闭合罩10的罩顶壁12)，以 形成柱透镜阵列20的凸面22，如图8所示。
同样地，在本发明中对闭合罩10的具体结构也不做特殊限定， 只要可以容纳柱透镜阵列20，并且形成填充腔室50即可。作为本发 明的一种具体实施方式，如图8所示，闭合罩10包括透明的罩顶壁 12、与该罩顶壁12连接的罩侧壁13(容易理解的是，罩侧壁13环 绕罩顶壁12设置)和与罩顶壁12相对的开口11，柱透镜阵列20设 置在闭合罩10的开口11中(参见图9和图10)，柱透镜阵列20的 凸面22与闭合罩10的罩顶壁12、罩侧壁13形成填充腔室50。应当 理解的是，此处所述的罩“顶”壁是指在使用过程中朝向观看者的壁， 而非在使用过程中位于顶部的壁。
如图8所示，柱透镜阵列20包括安装面21和凸面22，该安装 面21大致为平面，凸面22从安装面21上突出。设置安装面21的作 用在于，将所述柱透镜组件与显示面板组装在一起时，安装面21与 显示面板的表面相对设置。显示面板的表面包括该显示面板的出光面 和入光面。在图9和图10中所示的实施方式中，柱透镜阵列20的安 装面21与显示面板40的出光面相对设置。
在本发明中，形成罩顶壁12的材料的折射率应当与空气的折射 率近似，使得当本发明所提供的柱透镜组件与显示面板配合使用时， 罩顶壁12的折射率可以忽略。在本发明中，可以将整个闭合罩10 都设置为无色透明的，并且，使整个闭合罩10的折射率处处相同。 或者，可以将闭合罩10的罩顶壁12设置为具有较小的厚度，使得其 对光线的改变作用可以忽略。
下面结合图2、图3以及图9、图10描述本发明所提供的柱透 镜组件的工作原理。假设显示面板40上像素A、像素B、像素C、 像素D在立体显示时分别对应四幅视差图，而在平面显示时对应同 一幅图像。下文中将根据平面显示和立体显示两种情况介绍本发明所 提供的柱透镜组件的工作原理。
如图2和图10所示，当观看者需要平面显示时，储液槽30提 供的透明液体充满填充腔室50。显示面板40发出的光线进入柱透镜 阵列20中，经柱透镜阵列20传播至充满透明液体的填充腔室50中， 由于所述透明液体的折射率与柱透镜阵列20的折射率相同，因此， 光线传播的方向不变，最终光线穿过闭合罩10的罩顶壁12可以同时 进入观看者的左眼和右眼。在这种情况中，观看者的左眼和右眼都可 以透过透明液体和柱透镜阵列20看到显示面板40上的全部图像(包 括与像素A、像素B、像素C和像素D对应的图像)，此时观看者 感知到的图像为平面图像。
如图3和图9所示，当观看者需要立体显示时，储液槽30可以 使得填充腔室50中的至少部分透明液体(图9中为全部透明液体) 流回该储液槽30。如图9所示，显示面板8发出的光线进入柱透镜 阵列20中，经柱透镜阵列20传播至填充腔室50内的空气中，由于 空气的折射率与柱透镜阵列20的折射率不同，因此，光线经过柱透 镜阵列20的折射作用，传播的方向改变，最终光线穿过闭合罩10 的罩顶壁12进入观看者的眼睛。经过柱透镜阵列20的折射，从像素 A出射的光线对应视点A’，从像素B出射的光线对应视点B’，从 像素C出射的光线对应视点C’，从像素D出射的光线对应视点D’， 因此在视点A’、视点B’、视点C’和视点D’处分别可以看到与 像素A、像素B、像素C和像素D对应的图像，即与该四个像素分 别对应的四幅视差图中的一幅。例如，如图9所示，观看者左眼只看 到其中一幅视差图(对应像素C),右眼只看到其中另一幅视差图(对 应像素B)，通过大脑融合出立体显示效果。
由此可知，利用本发明所提供的柱透镜组件对显示装置的平面 显示模式和立体显示模式进行转换时，只需使得透明液体在填充腔室 50和储液槽30之间流动即可，无需扭曲柱透镜阵列20，也无需施加 驱动电场，操作简单、容易实现，并且所述柱透镜组件的结构简单， 成本较低。
在本发明中，柱透镜阵列20的折射率可以为1.5左右，透明液 体的折射率与柱透镜阵列的折射率相同，也为1.5左右。应当理解的 是，柱透镜阵列20和透明液体的折射率都是各向同性的。在本发明 中，所述透明液体可以是水或有机溶剂，也可以是含有溶质的水溶液 或有机溶液，或者是几种流体物质的混合物。当所述透明液体为含有 溶质的水溶液时，可以为偏钨酸盐溶液，通过调整透明液体的浓度可 以使该透明液体具有不同的折射率。例如，所述偏钨酸盐溶液可以为 偏钨酸铯溶液，当偏钨酸铯溶液中水的重量占30％，偏钨酸铯的重 量占70％时，折射率可达1.486。再或者，所述偏钨酸盐溶液可以是 偏钨酸铵溶液。
在本发明中，对储液槽30的具体结构并没有特殊的限制，只要 可以存储所述透明液体，并使得所述透明液体在填充腔室50和储液 槽30之间流动即可。例如，储液槽30可以包括存储容器和抽吸泵， 存储容器用于存储所述透明液体，抽吸泵用于驱动所述透明液体在填 充腔室50和存储容器之间流动。
作为本发明的一种实施方式，如图2、图3、图6和图7中所示， 储液槽30可以包括缸筒31、活塞32和活塞杆33，缸筒31上设置有 第一通孔，闭合罩10上设置有与所述第一通孔连通的第二通孔，活 塞32设置在缸筒31中，所述透明液体可以存储在活塞32与缸筒31 之间的空腔中，活塞杆33设置在活塞32上，通过操作活塞杆33可 以使所述透明液体在储液槽30和填充腔室50之间流动。在本发明中， 可以通过导管连通所述第一通孔和所述第二通孔，具体参见下文中的 详细描述。
当需要平面显示时，向上推动活塞杆33，使得活塞32推动透明 液体流动，并使透明液体通过所述第一通孔和所述第二通孔进入所述 填充腔室50内。需要立体显示时，向下拉动活塞杆33，使填充腔室 50内的透明液体从填充腔室50中流回缸筒31。整个切换过程只需要 向上推动活塞杆或向下拉动活塞杆，因此将储液槽30设置成上述结 构可以降低在进行所述平面显示模式和立体显示模式之间的切换时 的噪音，并且可以降低进行所述平面显示模式和立体显示模式之间的 切换时的能耗。
如上文中所述，闭合罩10可以包括环绕罩顶壁12四周设置的 罩侧壁13。在使用过程中，罩顶壁12是面对观看者的，为了使得在 将透明液体充入所述填充腔室50内、以及将所述透明液体抽回所述 储液槽30的过程中不影响使用者观看显示面板40显示的画面，优选 地，可以将所述第二通孔设置在罩侧壁13上。
在本发明中，对所述第二通孔的数量并没有特殊的限制，例如， 可以设置一个第二通孔，并且储液槽30包括一个与所述第二通孔对 应的第一通孔。
为了便于在实现立体显示时使所述透明液体全部流回储液槽30 中，优选地，可以将所述第二通孔设置在所述罩侧壁13的下部，并 将储液槽30设置在闭合罩10的下方。应当指出的是，此处的方向“下” 是指图2至图7中的方向“下”。在使用本发明所提供的柱透镜组件 实现平面显示和立体显示之间的切换时，所述柱透镜组件设置在显示 面板的出光面一侧，闭合罩10的罩顶壁12面对观看者。为了较好地 实现立体显示，需要将填充腔室50内的透明液体排空，由于第二通 孔设置在罩侧壁13的下部，因此，在需要将填充腔室50内的透明液 体排空时，所述透明液体可以在自身的重力作用下向下流，并通过所 述第二通孔流入储液槽30。
或者，如图4所示，所述第二通孔可以包括第二上通孔13a和 第二下通孔13b，第二上通孔13a位于罩侧壁13的上部，所述第二 下通孔13b位于罩侧壁13的下部，储液槽30还包括上连通管34和 下连通管35(如图2和图3所示)，所述第二上通孔13a通过上连 通管34与所述第一通孔相连，第二下通孔13b通过下连通管35与所 述第一通孔相连，储液槽30设置在闭合罩10的下方。应当理解的是， 此处所述的“上、下”方向仍然是所述柱透镜组件在使用状态下的“上、 下”方向，也是图2至图4中的“上、下”方向。
将所述第二上通孔13a设置在罩侧壁13的上端可以确保所述透 明液体充满所述填充腔室50，将第二下通孔13b设置在罩侧壁13的 下部可以确保将所述填充腔室50内的所述透明液体完全排出。
如上文中所述，罩侧壁13环绕罩顶壁12设置，因此，如图2 和图3所示，罩侧壁13包括上壁、下壁、左壁和右壁，所述左壁和 所述右壁连接所述上壁和所述下壁，优选地，所述左壁和右壁均与柱 透镜阵列中的柱透镜的长度方向平行设置，应当理解的是，此处的方 位词“上、下、左、右”分别指图2和图3中的“上、下、左、右” 方向。为了便于布置上连通管34和下连通管35，优选地，可以将第 二上通孔13a和第二下通孔13b均设置在罩侧壁13的左壁上，或者 可以将第二上通孔13a和第二下通孔13b均设置在罩侧壁13的右壁 上
进一步优选地，可以将第二上通孔13a设置在罩侧壁13的右壁 的最上部，上连通管34包括与第二上通孔13a同轴设置的管水平部 34a(即，当管水平部34a与第二上通孔13a相连时，第二上通孔13a 与管水平部34a同轴)和与该管水平部34a相连的管竖直部34b，该 管竖直部34b与所述第一通孔相连。在这种情况中，第二下通孔13b 也设置在右壁上。应当理解的是，虽然在这种实施方式中，第二上通 孔13a和第二下通孔13b均设置在了右壁上，但这并不构成对第二上 通孔13a和第二下通孔13b的设置位置的限制，第二上通孔13a和第 二下通孔13b也可以同时设置在罩侧壁13的左壁上。
由于第二上通孔13a设置在罩侧壁13的右壁的最上部，根据连 通管原理，第二上通孔13a中的液位与管水平部34a的液位相同，当 第二下通孔13b封闭时，透明液体不会从第二上通孔13a中流向管水 平部34a，因此，设置管水平部34a的一个目的在于，防止透明液体 充满所述填充腔室50时，透明液体从第二上通孔13a中流出。设置 管竖直部34b的一个目的在于，减小柱透镜组件所占的安装空间，从 而可以减小利用本发明所提供的柱透镜组件的显示装置的整体体积。
为了便于在实现立体显示时，将填充腔室50中的透明液体完全 排出，优选地，可以将第二下通孔13b设置在罩侧壁13的最下部。
如图5所示，所述第一通孔可以包括第一上通孔31a和第一下 通孔31b，所述第一上通孔31a设置在缸筒31的筒顶壁上，所述第 一下通孔31b设置在缸筒31的筒侧壁上，如图2和图3所示，所述 第一上通孔31a通过上连通管34与所述第二上连通孔相连，所述第 一下通孔31b通过下连通管35与所述第二下连通孔相连，所述第一 上通孔31a与上连通管34的管竖直部34b相连，当所述透明液体充 满所述填充腔室50时(此种情况对应于平面显示)，活塞32可以将 所述第一下通孔31b封闭。
利用活塞32将所述第一下通孔31b封闭的优点在于，可以防止 透明液体填充满所述填充腔室50时透明液体从所述填充腔室50中流 回储液槽30。具体地，由于第二上通孔13a与上连通管34的管水平 部34a平齐，因此，所述透明液体不会通过第二上通孔13a流回储液 槽30，由于第一下通孔31b是封闭的，因此，所述透明液体不会通 过第一下通孔31b流回储液槽30，从而可以使显示装置具有稳定的 平面显示效果。
在本发明中，对活塞32的具体结构并没有特殊的限制，只要可 以推动透明液体流动，并在平面显示时将第一下通孔31b封闭即可。 作为本发明的一种实施方式，如图2至图5所示，活塞32可以包括 活塞水平部32a和活塞竖直部32b，活塞水平部32a的底部与活塞杆 33相连，活塞竖直部32b从活塞水平部32a上朝向所述缸筒31的筒 顶壁延伸，当所述透明液体充满所述填充腔室50时，活塞竖直部32b 向上移动至接触缸筒31的筒顶壁，从而可以将所述第一下通孔31b 封闭。
在本发明中，通常将第一下通孔31b设置在所述缸筒31的筒侧 壁的顶部，即靠近缸筒31的筒顶壁的位置处，从而可以防止在需要 进行立体显示时，储液槽30中的透明液体逆流回所述填充腔室50 中。活塞32设置为包括活塞竖直部32b和活塞水平部32a的优点还 在于，当活塞竖直部32b封闭所述第一下通孔31b时，活塞水平部 32a仍然与缸筒31的筒顶壁之间保持一段距离，从而不会撞到所述 缸筒31的筒顶壁，进而不会损坏所述缸筒31的筒顶壁。
作为本发明的一种实施方式，如图1、图8至图10中所示，柱 透镜阵列20可以包括并排设置(即平行设置)的多个柱透镜20a， 该多个柱透镜20a的底面形成安装面21。
为了使立体显示时效果更稳定，进一步地，如图8所示，每个 柱透镜2a的底面的宽度(此处所述的宽度的方向是指图8中的左右 方向)大于与该柱透镜组件配合使用的显示面板40的每列像素的宽 度。优选地，所述每个柱透镜2a的宽度与配合使用的显示面板的两 列像素的宽度相当，当显示面板显示立体图像时，这两列像素分别显 示左眼图像和右眼图像。由于每个柱透镜20a可以对应两列像素，当 进行立体显示时，通过柱透镜20a可以改变从两列像素出射的光线的 方向，两列像素显示的图像分别射入观察者的左眼和右眼，从而实现 立体显示效果。每个柱透镜20a还可以对应四列像素，四列像素分别 用于显示四幅视差图，如图9所示。
优选地，所述柱透镜组件还可以包括驱动组件，该驱动组件用 于驱动活塞杆33沿竖直方向上、下移动，从而控制所述透明液体流 出或流入缸筒31，使得所述透明液体充满或排出填充腔室50。
在本发明中，对驱动组件的具体结构并没有特殊的限制，只要 可以驱动活塞杆33沿竖直方向上、下移动即可。例如，所述驱动组 件可以包括齿轮齿条传动机构。优选地，如图2和图3所示，所述驱 动组件可以包括凸轮60，该凸轮60可旋转地设置在活塞杆33的下 方，该活塞杆33的下端面与凸轮60的表面相接触。应当指出的是， 活塞杆33的下端面可以与凸轮60的表面之间产生相对滑动。
本领域技术人员应当理解的是，凸轮60的外表面上的各个点与 凸轮60的旋转中心之间的距离并不是处处相等，所以随着凸轮60 的旋转，活塞杆33可以向上或向下移动。
如图2和图3所示，在本发明所提供的实施方式中，凸轮60的 旋转中心为O，点a为凸轮60外表面上距离旋转中心O最远的点， 其中，点a与旋转中心O之间的距离为d1，点b为凸轮60外表面上 距离旋转中心O最近的点，其中，点b与旋转中心O之间的距离为 d2(d1＞d2)。
如图2所示，当需要进行平面显示时，使凸轮60的外表面上距 离凸轮60的旋转中心O最远的点a与活塞杆33的底部相接触，以 使活塞32处于最高的位置，在此位置处，活塞竖直部32b将所述第 一下通孔31b封闭，此时缸筒31内透明液体充满填充腔室50。为保 持该平面显示状态，使凸轮60保持这种状态(即，使凸轮60的外表 面上距离凸轮60的旋转中心O最远的点a保持与活塞杆33的底部 相接触)，从而使得凸轮60支撑活塞杆33，以防止活塞32下行。
需要切换为立体显示时，转动凸轮60，使点a向下移动，活塞 杆33在自身重力以及缸筒31内透明液体的重力作用下下行，透明液 体回到缸筒31内，继续转动凸轮60直至凸轮60的外表面上距离凸 轮60的旋转中心最近的点b与活塞杆33的底部相接触，以使活塞 32处于最低的位置(如图3所示)，此时填充腔室50内的透明液体 至少部分地流回缸筒31。为保持该立体显示状态，使凸轮60保持这 种状态(即，使凸轮60的外表面上距离凸轮60的旋转中心O最近 的点b保持与活塞杆33的底部相接触)，从而使得凸轮60支撑活塞 杆33，以防止活塞杆33移动。
当活塞杆33下行时，依靠的是活塞32以及缸筒31内透明液体 的重力，无需其他外力，从而节约了电能。并且，只需利用电机等驱 动元件驱动凸轮60转动即可。包括凸轮60的驱动组件结构简单，从 而可以节约安装空间，降低所述柱透镜组件的总体尺寸。
如图9和图10所示，作为本发明的另一个方面，提供一种显示 装置，该显示装置包括显示面板40，其中，所述显示装置还包括本 发明所提供的上述柱透镜组件，该柱透镜组件设置在显示面板40上。
应当指出的是，此处所述的“柱透镜组件设置在显示面板上” 并非指所述柱透镜组件设置在显示面板的上方，而是指柱透镜组件与 显示面板40配合使用，射入显示面板40或者从显示面板40射出的 光线可以经过所述柱透镜组件。
在本发明中，对柱透镜组件在显示装置中的设置位置并没有特 殊的限制。例如，可以将柱透镜组件的安装面21设置在显示面板40 的出光面一侧。再例如，当显示面板40为液晶显示面板时，所述显 示装置还包括背光模组，可以将所述柱透镜组件设置在显示面板40 的出光面一侧，也可以将所述柱透镜组件设置在背光模组与显示面板 的入光面之间。
可以根据显示面板40的具体形式来确定将柱透镜组件设置在显 示面板40的面向观看者的一侧还是显示面板的背离观看者的一侧。
优选地，柱透镜阵列20中的每个柱透镜20a的长度方向与显示 装置中的显示面板的显示区域的高度(此处所述的“高度”方向是指 图2和图3中的“上、下”方向)方向一致。优选地，所述柱透镜组 件的柱透镜阵列20的每个柱透镜20a的宽度与显示面板40的两列像 素的宽度相匹配。优选地，所述柱透镜组件的柱透镜阵列20的每个 柱透镜20a的宽度与显示面板40的四列像素的宽度相匹配。
本发明所提供的上述显示装置可实现2D/3D切换，所述柱透镜 组件中的填充腔室50内充满所述透明液体时，显示装置实现2D显 示(即，平面显示)；所述柱透镜组件中的所述填充腔室50内的所 述透明液体至少部分地被排出时，显示装置实现3D显示(即，立体 显示)。
容易理解的是，本发明所提供的显示装置的立体显示效果为裸 眼3D效果。
可以将所述实现平面显示与立体显示切换的柱透镜组件设置在 所述显示装置的壳体中。
利用本发明所提供的柱透镜组件对显示装置的平面显示模式和 立体显示模式进行转换时，只需使得透明液体在填充腔室50和储液 槽30之间流动即可，无需扭曲柱透镜阵列，也无需施加驱动电场， 操作简单容易实现，并且所述柱透镜组件结构简单，成本较低。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用 的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术 人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和 改进，这些变型和改进也视为本发明的保护范围。
