下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
在本发明的实施例中, 立体成像可以指三维显示或自由立体显示。
除了分辨率较低之外, 固定折射率的微透镜阵列还使得立体成像装置无 法在立体成像和二维成像之间切换, 而且当立体成像装置旋转 90度之后, 立体成像的效果会完全消失。 另外, 由于每个微透镜覆盖了多个像素, 因此 会造成串扰( crosstalk ), 即一只眼睛看到了另一只眼睛应该看到的图像。 为 了克服上述固定折射率的微透镜阵列存在的不足之处,本发明的实施例提出 了一种使用活动的(或电可调)棱镜阵列和时分复用技术相结合的自由立体 显示方案。
图 1 是根据本发明的一个实施例的一种立体成像装置 100 的结构示意 图。 立体成像装置 100包括: 显示面板 110和电光调制层 120。
显示面板 110 包括多个像素单元(或显示单元) 111, 用于按照时分方 式显示图像, 例如, 显示不同投射方向的图像, 其中不同投射方向对应于不 同观察方向。 电光调制层 120包括多个电光调制单元 121, 分别布置在与多 个像素单元对应的位置, 用于根据所施加的时分变化的电场 E, 将多个像素 单元显示的图像的光线交替地偏转至不同的投射方向, 以在呈现立体图像, 例如, 在中心深度平面上产生棵眼能够看到的立体图像。
例如, 上述多个电光调制单元可以直接设置在像素单元上, 或者设置在 完整覆盖或者包覆多个像素单元的位置处, 例如, 在像素单元与电光调制单 元之间有一定间隔 (空间 )/或者间隔物 (填充物, 隔板、 绝缘板等。)
根据本发明的实施例, 电光调制层可以由液晶构成。 液晶在施加电场后 能够改变折射率, 不同的电场可以对应于不同的折射率, 即釆用液晶在电光 调制层形成电可调的棱镜阵列。 当光线通过施加了电场的液晶时, 出射光的 相位差会随着外加电场的变化而变化。 本发明的实施例并不限于此, 电光调 制层也可以由施加电场时能够改变折射率的其它晶体材料构成, 例如, 可以 由锂酸铌晶体构成。
根据本发明的实施例, 可以在液晶的两个相对的平面上布置电极, 并且 通过给电极施力口电压来给液晶施力口电场。
在电光调制层 120中,每个电光调制单元包括的液晶在施加电场之后相 当于一个微透镜, 多个电调制单元形成微透镜阵列。 图 2是根据本发明的实 施例的电光调制单元施加电场前后的液晶分子状态的示意图。 例如, 参见图 2中的 (a ), 对于列向型液晶材料来说, 液晶分子是棒状的并且是单轴的, 棒状的纵向为长轴方向。参见图 2中的(b ),在一个平面内排列的液晶分子, 在没有施加电压的情况下, 其长轴指向特定的方向。 参见图 2中的 (c ), 在 所施加的电压超过液晶的阔值电压时, 液晶分子会被重定向, 即进行机械旋 转, 从而使得入射光线的相位发生偏移。 这种机械旋转是由施加的电压诱导 偶极距产生的扭矩所引起的。
显示单元 110上的三个像素单元(例如, 红、 黄和蓝色像素单元) 111 可以构成一个显示像素 (或图像像素), 根据本发明的实施例并不限于此, 例如, 也可以是显示单元 110上的每个像素单元构成一个显示像素。
不同的投射方法对应的观察方向可以包括一个左眼观察方向(例如, 图
1中的实线箭头所指的方向)和一个右眼观察方向 (例如, 图 1中的虚线箭 头所指的方向), 根据本发明的实施例并不限于此, 例如, 不同的观察方向 可以包括多个左眼观察方向和多个右眼观察方向, 以供多人同时观看立体图 像。
例如, 为了使得立体成像装置呈现出来的立体图像的分辨率为全部像素 单元, 所施加的电场要满足在视觉暂留的时间内用全部像素显示每个方向的 图像。给多个像素单元施加电场时所釆用的时分方式可以与显示面板显示不 同投射方向的图像时所釆用的时分方式一致,使得人眼可以在不同的观察方 向上观察到多个像单元呈现的立体图像。以两个投射方向为例,在第一时段, 每个像素单元显示第一投射方向 (例如, 对应于右眼观察方向)的图像, 而 与该像素单元对应的电光调制单元根据所施加的第一电场将该像素单元发 出的光线偏转至第一投射方向, 在第二时段, 该像素单元显示第二投射方向 (例如, 对应于左眼观察方向)的图像, 而该电光调制单元根据所施加的第 二电场将该像素单元发出的光线偏转至第二投射方向。
本发明的实施例的技术方案可以按照时分方式显示不同方向的图像, 并 且根据所施加的时分变化的电场,将多个像素单元显示的图像的光线偏转至 不同的方向,使得每个方向上呈现的图像的分辨率为显示面板的全部像素单 元, 从而提高了自由立体显示的分辨率。
根据本发明的实施例, 电光调制层还在未施加电场的情况下使得显示面 板呈现二维图像。
图 3是根据本发明的实施例的立体成像装置的不同显示状态的示意图。 参见图 3中的 (a ), 在施加第一电场的情况下, 液晶在第一电场的作用下形 成棱镜, 以将背光射入显示面板后产生的光线偏转至右眼观察方向。 参见图 3中的(b ), 在施加第二电场的情况下, 液晶在第二电场的作用下形成棱镜, 以将背光射入显示面板后产生的光线偏转至左眼观察方向。 参见图 3 中的 ( c ), 在没有施加电场的情况下, 液晶将不会使光线偏转, 在这种情况下, 可以呈现二维的图像。
应理解的是, 本发明的实施例并不限于所有像素单元在同一时段显示相 同投射方向的图像, 例如, 也可以是在第一时段, 第一部分像素单元显示第 一投射方向的图像, 而第二部分像素单元显示第二投射方向的图像, 在第二 时段, 第一部分像素单元显示第二投射方向的图像, 第二部分像素单元显示 第一投射方向的图像, 只要能够在人眼视觉暂留的时间内在不同观察方向观 察到所有像素单元显示的图像即可, 换句话说, 只要第一时段与第二时段之 和小于人眼视觉暂留的时间即可。
根据本发明的实施例, 每次显示的是双目立体视差的一个视野(view ), 而没有像常规技术方案那样将显示面板进行空间分割, 因此, 相比常规技术 具有较高的分辨率。
应理解的是, 在具体实现时, 可以在电光调制层上方覆盖玻璃盖板, 并 且显示面板和电光调制层之间以及电光调制层与玻璃盖板之间可以根据需 要设置其它介质。
本发明的实施例可以设置专门的控制模块控制显示面板按时分方式显 示不同投射方向的图像, 同时控制电光调制单元上施加的电场按照时分方式 变化, 以在不同的投射方向上显示相应的图像, 从而形成棵眼能够观察到的 立体图像。
根据本发明的实施例, 多个电光调制单元与多个像素单元——对应, 电 光调制层包括: 电光调制介质层, 电调制介质层包括电光调制介质, 并且具 有出光面以及入光面; 第一电极层, 包括位于电光调制介质层的出光面的电 极; 第二电极层, 包括位于电光调制介质层的入光面的电极, 其中多个电光 调制单元中的每个电光调制单元包括位于电光调制介质层中的电光调制介 质、位于第一电极层中的至少一个第一电极和位于第二电极层中的至少一个 第二电极, 电光调制介质根据至少一个第一电极与至少一个第二电极之间接 收的电压配置所形成的电场,将电光调制介质对应的像素单元显示的图像的 光线偏转至预设的投射方向, 用于将光线偏转至预设的投射方向。
根据本发明的实施例, 上述电极可以由透明导电材料制成, 例如, 可以 是氧化铟锡(Indium Tin Oxide , ITO )之类的透明导电材料。 电光调制介 质可以包括液晶或铌酸锂晶体等晶体材料, 即电光调制介质层可以是液晶层 或其它晶体层。上述至少一个第二电极可以是连续的 ΙΤΟ透明导电膜。例如, 透明导电膜电极分布在盖板的内表面和电解质基板的上方, 除了用于产生电 场, 还用于分隔显示面板和液晶层。 本发明的实施例可以针对每个像素上设 置可调液晶棱镜, 即设置像素级别的可调液晶棱镜。 因此, 本发明的实施例 能够消除像素之间的串扰现象。
根据本发明的实施例, 多个电光调制单元中的每个电光调制单元包括: 至少两个第一电极, 用于分别接收至少两个电压, 至少一个第二电极作为公 共电极, 用于接收参考电压。
上述至少两个第一电极可以是一系列导电条纹, 这些导电条纹可以均匀 分布, 也可以非均匀分布, 只要布置成在接收电压时能够使得电光调制单元 产生微透镜的效果或者线性相位的效果即可。每个第一电极上接收的电压与 参考电压之间的电势差在液晶层形成相应的电场。 参考电压例如可以是 0V。
根据本发明的实施例, 多个电光调制单元中的每个电光调制单元包括多 个第一电极,用于分别接收多个电压,其中多个电压中的至少两个电压不同, 使得电光调制介质在多个第一电极接收的多个电压与作为公共电极的至少 一个第二电极接收的参考电压所形成的电场的作用下产生离轴透镜的功能, 用于将光线偏转至预设的投射方向。
根据本发明的实施例, 通过调整这些电极上接收的电压, 可以在液晶层 中产生电场, 从而给液晶层促生一个需要的相位配置。 不同的相位配置取决 于不同的电压配置和电极分布。 例如, 每个电光调制单元可以包括 4个第一 电极, 其中一个电极位于像素单元的边缘, 接收的电压分别为 VI、 V2、 V3 和 V4。 每个电光调制单元包括的第一电极可以多于 4个或少于 4个。 液晶 的平滑特性使得 4个电极足以产生近似平滑的相位分布。
根据本发明的实施例, 多个电光调制单元中的每个电光调制单元包括两 个第一电极和连接在两个第一电极之间的电阻膜, 两个第一电极用于分别接 收两个电压, 其中两个电压不同, 使得电光调制介质在两个第一电极接收的 两个电压与作为公共电极的至少一个第二电极接收的参考电压所形成的电 场的作用下产生具有线性相位倾斜的透镜的功能, 用于将光线偏转至预设的 投射方向。

上面描述了本发明的实施例的立体成像装置和显示器。 下面详细描述本 发明的实施例的立体成像装置的电极配置。
图 6是根据本发明的一个实施例的立体成像装置 600的示意性剖面图。 在本实施例中, 为了描述方便, 仅仅示出了电光调制层的六个电光调制 单元。 在每个电光调制单元中, 连续的透明导电膜(即第二电极)设置在液 晶电光调制单元的一面 (例如, 入光面), 四个导电条纹(第一电极)设置 在液晶电光调制单元的另外一面 (例如, 出光面), 并通过在透明导电膜上 接收公共电压, 在四个导电条纹上接收相应的电压来产生电场, 从而使得相 应的电光调制单元产生离轴柱面透镜的效果。 在整个电光调制层中, 连续的 透明导电膜可以是一个整体, 而每个导电条纹可以跨过一列像素单元。
参见图 6, 立体成像装置 600包括显示面板 610、 液晶 620、 玻璃盖板 630、 第一电极 640和第二电极 650。 第一电极 640是一系列导电条纹, 这些 导电条纹可以均勾分布, 也可以非均勾分布。 每个像素单元上可以布置 5个 第一电极,并且每个像素单元的边缘电极同样是相邻像素的边缘电极,这样, 每个像素单元上实际平均布置了 4个电极, 并且分别接收 4个电压 VI、 V2、 V3、 和 V4, 例如, VI、 V2、 V3、 和 V4可以是 5V左右的电压, 根据本发 明的实施例并不限于此, 例如, 根据实际需要, 可以选择 2.6V至 21V之间 的电压。第二电极 650为连续的透明导电薄膜,位于显示面板 610与液晶 620 之间。 通过调整电极电压 Vn, 可以在每个像素单元对应的液晶上产生满足 要求的相位分布。 由于液晶具有平滑不连续电压的趋势的性质, 因此, 4个 以上的电压分布足以产生满足要求的相位分布。在第一电极上接收的电压可 以以很高的频率(例如, 50HZ左右)在 +Vn和 -Vn之间切换, 以便保持直 流(DC ) 电压的平稳。 每个像素单元尺寸可以设置为小于等于 75μπι。
图 7是根据本发明的另一实施例的立体成像装置 700的示意图。
在本实施例中, 为了描述方便, 仅仅示出了电光调制层的六个电光调制 单元。 在每个电光调制单元中, 连续的透明导电膜(即第二电极)设置在液 晶电光调制单元的一面(例如,入光面), 连接在导电条纹之间的电阻膜(第 一电极)设置在液晶电光调制单元的另一面 (例如, 出光面), 并通过在透 明导电膜上接收公共电压, 在导电条纹上接收相应的电压来产生电场, 从而 使得相应的电光调制单元产生具有线性相位的透镜的效果。在整个电光调制 层中, 连续的透明导电膜可以是一个整体, 而连接在导电条纹之间的电阻膜 可以跨过一列像素单元。
参见图 7, 立体成像装置 700包括显示面板 710、 液晶 720、 玻璃盖板 730、第一电极 740和第二电极 750。第一电极 740由连接在两个导电条纹之 间的电阻膜构成。 相邻像素单元的第一电极之间存在电极间隙。 每个第一电 极的两个导电条纹接收不同的电压 V (例如, V = 0 V>Vth ), 从而在电阻 膜上形成线性分布的电压。具体而言,两个导电条纹可以为 ITO透明导电膜。 电压 V = 0和 V>Vth分别接收在两个导电条纹上。由于电阻膜具有导电率 R, 所以连接在两个导电条纹之间的电阻膜有线性的电压下降,从而会导致液晶 呈现一种线性的相位斜坡, 如图 7中的折线所示。
图 8是根据本发明的另一实施例的立体成像装置 800的示意图。 图 8是 图 8的实施例的立体成像装置在不同状态之间切换的示意图。立体成像装置 800包括显示面板 810、 液晶 820、 玻璃盖板 830、 第一电极 840和第二电极 850。
图 8的实施例与图 7的实施例类似, 第一电极 840也是由连接在两个导 电条纹之间的电阻膜构成, 不同的是, 图 8的实施例釆用了复用导电条纹的 方案, 即相邻的电光调制单元共用一个导电条纹, 并釆用时间和空间间隔的 波束控制来实现最大的分辨率。 具体而言, 每个像素单元有两个导电条纹, 通过在两个导电条纹上接收电压 VI和 V2可以产生一个三角形的相位延迟 分布, 如图 8中的折线所示。 如图 8中的 (a ) 所示, 在第一时段(例如, 第一图像帧)通过相邻像素的光线会分别偏向两个不同的方向(到左眼和右 眼方向)。 如果, 在第二副图像帧时候, 我们交换 VI和 V2, 这样三角形的 相位分布会交换。 这个相位分布会让光偏转和之前帧不同的方向。 因此, 与 在第一帧将所有像素单元的光线偏转到左眼观察方向, 而在第二帧将所有像 素单元的光线偏转到右眼观察方向的方法不同, 在实施例中, 在第一帧将选 择第一部分像素单元的光线偏转到左眼观察方向, 并将选择的第二部分像素 单元的光线偏转到右眼观察方向, 然后在下一帧将选择的第一部分像素单元 的光线偏转到到右眼观察方向, 并将选择的第二部分像素的光线偏转到左眼 观察方向。 由于人类视觉系统的持久性, 可以观察到一个方向上两个时间上 的不一致的画面好像是一个画面,从而能够获得和图 7的实施例一样的画面 分辨率。
图 9是根据本发明的实施例的立体成像装置的两种显示状态的示意图。 图 9中的 (a )和(b )分别显示了图 8中的 (a )和(b ) 中相应的三角形相 位模式的光学行为特性在两个不同状态之间切换。 图 9 中的 (a )描述了第 一种状态, 即在第一时段, 像素单元 A将光线向左眼观察方向偏转, 像素单 元 B将光线向右眼观察方向偏转。 图 9中的 (b )描述了第二种状态, 即在 第二时段,像素单元改变相位模式导致偏转方向的交换, 即像素单元 A将光 线向右眼观察方向偏转, 像素单元 B将光线向左眼观察方向偏转。
图 10是根据本发明的另一实施例的立体成像装置的电极配置的示意图。 在本实施例中, 立体成像装置的电极配置可以包括分布在立体成像装置 的液晶层一侧(例如, 出光面)的多个第一电极, 以及分布在立体成像装置 的液晶层的另一侧(入光面)的多个第二电极, 其中多个第一电极与多个第 二电极可以正交布置, 即第一电极纵向与第二电极的纵向成 90度。 本发明 的实施例并不限于此,例如,第一电极和第二电极之间的夹角也可以小于 90 度。 与前面的实施例不同的是, 第一电极和第二电极均釆用多个导电条纹或 者包括两个导电条纹和连接在两个导电条纹之间的电阻膜。 在本实施例中, 在立体成像装置处于第一方向时, 可以将多个第一电极 接收用于产生透镜效果所需的电压, 而将作为公共电极的多个第二电极接收 相同的参考电压 (例如, ov ), 并且在立体成像装置经过旋转处于第二方向 时, 将多个第一电极作为公共电极接收相同的参考电压, 并将多个第二电极 接收用于产生透镜效果的电压, 使得用户可以在立体成像装置旋转的情况 下,仍然可以看到立体图像。下面以第一电极与第二电极正交为例进行说明。 应理解, 上述参考电压可以大于 0V, 例如, 0.5V。 当一个电极(例如, 第 一电极或第二电极)上接收的参考电压为例如 ¼伏时, 与该电极对应的另 一电极(例如, 第二电极或第一电极)应该接收纯交流电压再加上 V。伏。
具体而言, 可以在液晶层的顶面和底面分别设置 ITO 透明导电膜电极
(包含一系列的导电条纹)。 例如, 对于每个像素单元 P(m,n), 在液晶层的 顶面沿 y方向上设置 4个电极, 并在底面在 X方向上设置 4个电极。 假设共 有 M x N个像素单元, 这样会有 4M个电极在 X方向上, 4N个电极在 y方 向上。 另外, 可以优化相邻电极之间的间隔, 使得当一个平面上的电极置于 相同电势时, 在这些电极附近会产生几乎平滑的电势分布。 例如, 可以将位 于液晶层的同一液晶平面上的电极之间的距离设置成一样或者设置成小于 两个电极所在液晶平面之间的距离。
根据本发明的实施例, 在立体显示装置工作时, 为了使显示对准一个方 向, 可以给一个液晶平面上的所有电极都接收 0V电压以作为接地平面或者 接收一定的电压以作为参考平面, 而将另一液晶平面上的电极接收产生离轴 透镜模式(off-axis lens patterns )所需的电压。 这样可以保证自由立体显示 轴位于相应的方向。 当立体成像装置检测到自身旋转了 90度, 则可以通过 交换两个电极平面上的电压的设置将自由立体显示轴切换到另一方向。
下面以液晶透镜为例详细本发明的实施例的时分复用方法。
为了能使用户看到立体图像, 可以将离轴液晶透镜或者具有相位斜坡的 液晶透镜快速地在不同的状态之间切换。
例如, 在两个投射方向 (Q=2 )且刷新频率 (refresh rate ) frefresh=25Hz 的情况下, 需要满足切换时间 (switching time ) T < 20ms, 在 frefresh=25Hz且 投射方向 Q = 4的情况下, 切换时间 1 < 101^, 而在投射方向 Q = 8的情况 下, 则切换时间 T < 5msec, 其中切换时间为 τ = l/(Q*frefresh)。 液晶从一个状 态切换到另外一个状态需要一定的时间(对于传统的平面列向型液晶分子而 言, 接通时间大约为 2ms, 松弛时间大约为 100ms )。 这个接通时间和松弛 时间是光学单元(cell ) 的厚度、 液晶材料、 所接收的电压和温度的函数。 一种减小接通时间和松弛时间的方法是过驱动电极(即接收高的 +ve or -ve 电压脉冲), 釆用过驱动电极方式可以迫使液晶分子朝想要的状态变化。 然 后, 通过脉动地产生显示背光, 能够避免残留瞬态切换效应。 这样做的目的 是确保在液晶的相位分布稳定之前光线不会入射到液晶透镜阵列上。根据本 发明的实施例不限于此, 也可以釆用其他快速切换的技术, 例如, 可以使用 π型光学单元( pi-cell )的配置, 其切换时间比平面对齐( planar aligned )的 光学单元要快很多。
这样, 在实现多用户 /多投射方向的方案时, 需要最小化切换时间。 这可 以通过减少光学单元之间的间距空隙来实现。 当然, 也可以釆用 pi-cell和过 驱动电压的方式来缩短切换时间。
