随着显示技术的发展， TN盒的使用越来越广泛。 图 1所示为现 有的 TTSr盒示意图：玻璃基板 11和玻璃基板 12以预定间距平行设置， 在基板 11、 基板 12的内表面上分别具有透明电极 13、 透明电极 14， 透明电极 13、 14的内表面上分别具有配向层 15、 配向层 16, 且配向 层 15和配向层 16的摩擦方向相互垂直；在配向层 15和配向层 16之 间充满扭曲向列液晶 17。 当透明电极 13和透明电极 14之间没有外 加电压时， 该 ΤΝ盒的状态如图 1所示， 此时该 ΤΝ盒能使偏振方向 光的偏振方向相垂直的线偏振光出射； 当透明电极 13和透明电极 14 间的外加电压大于等于阈值电压时，液晶 17的长轴方向沿电场方向， 此时该 ΤΝ盒不改变入射线偏振光的偏振状态。

现将参考附图更全面地描述本发明，在附图中显示了本发明的示 范性实施方式。
图 2所示为本发明实施例提供的一种逐点控制 TN盒沿光路方向 的剖面图。 该逐点控制 TN盒包括： 第一控制层、 第二控制层以及位 于第一控制层和第二控制层之间的扭曲液晶 20。 图中为方便表示， 仅画出该剖面图的局部， 值得说明得是， 具体实施时， 在所述第一控 制层和第二控制层的四周边缘， 采用封框胶等将所述扭曲液晶 20封 闭在所述第一控制层和第二控制层之间。
其中， 第一控制层包括： 第一透明基板 21、 若干个笫一电极 22 和第一配向层 23， 且第一电极 22和第一配向层 23均是透明的。 所 述第一电极 22为波浪形带状。各第一电极 22彼此绝缘间隔排列于第 一透明基板 21上。 所述第一配向层 23成形于各第一电极 22间隙内 及上表面且上表面为一平面， 可在具有第一电极 22的第一透明基板 21上涂抹配向剂菽得。
第二控制层包括： 第二透明基板 26、 若干个第二电极（由于所 述第二电极的排列方向垂直于所述第一电极的排列方向，图中只能示
.出一个第二电极） 、 和第二配向层 24, 且第二电极 25和第二配向层 24均是透明的。 第二控制层的结构类似于第一控制层。 所述第二电 极 25为波浪形带状。 各第二电极彼此绝缘间隔排列于第二透明基板 26上。 所述第二配向层 24成形于各第二电极 25间隙内及上表面且 上表面为一平面，扭曲液晶 20位于所述第一配向层 23和第二配向层 24之间。
所述第一控制层和第二控制层平行。 所述第一电极 22和所述第 二电极 25的排列方向相互垂直， 第一电极 22所处平面和第二电极 25所处平面间的间距小于所述第一透明基板 21和第二透明基板 26 间的间距。 此外， 读 TN盒还可以包括设置于所述第一配向层 23和 第二配向层 24之间的衬垫料（图中未示出） ， 用于确保第一， 二控 制层间距为预定间距。
图 3为去掉图 2中的第二控制层和扭曲液晶 20后看到的第一控 制层的第一电极结构示意图。 图 4为去掉第一控制层和扭曲液晶 20 后看到的第二控制层的第二电极结构示意图。 图 3、 图 4中， 第一电 极 22、 第二电极 25所具有的两长边均为波浪形。 当然， 具体实施中 不限于此， 还可以选择电极的一个长边为波浪形。
图 5所示为图 2所示的逐点控制 TN盒的电极分布示意图 ,且仅 示意性画出了 8个第一电极 al至 a8， 8个第二电极 bl至 b8。以下说 明图 5所示€点控制 TN盒的工作原理。
由图 5可知， 所述第一电极与所述第二电极交叠，将该逐点控制 TN盒划分为 8 x 8个像素显示区，各像素区的底部为第一控制层，上 部为第二控制层， 中间为扭曲液晶。 为方便说明， 将图 5所示的 8 x 8个像素显示区看成一个 8 x 8的二维像素矩阵， 该二维像素矩阵的 列代表第一电极 22， 该二维像素矩阵的行代表第二电极 25, 用 表 示第 i行（i=l,...,8 )和第 j(j=l,...,8)列处的像素显示区， 则当 的上 下电极没有外加电压时，在所述第一配向层 23和第二配向层 24的作 用下， 内的液晶扭曲 90度， 偏振方向平行于入射基板的摩擦方向 的线偏振光经 后，出射光为偏振方向与入射线偏振光的偏振方向垂 直的线偏振光， 以下为方便描述，将此时该 内的扭曲液晶状态称为 第一状态； 当向第 i行电极、第 j列电极在同一时刻分别施加电压 、 ^且 和 之差大于等于所述扭曲液晶的阈值电压时 , aij内的扭曲 液晶分子在电场力作用下、分子的长轴方向沿垂直于所述第一透明基 板 21和第二透明基板 26的方向排布，此时 .不改变入射的线偏振光 的偏振状态， 以下为方便说明，将此时该 内的扭曲液晶状态称为第 二状态。 可见， 通过向不同行不同列的电极外加电压， 可以实现对各 像素显示区内液晶状态的单独控制。
此外， 该逐点控制 TO盒还能实现： 使局部显示区内的液晶处于 所述第一状态和第二状态之中的一个状态，而其它显示部位的扭曲液 晶处于第一状态和第二状态之中的另一个状态。为实现该功能， 本发 明提供的逐点控制 TN盒采用逐行扫描或逐列扫描的方式进行液晶状 态的切换控制，且扫描频率的选择需要使得该逐点控制 TN盒中采用 的扭曲液晶为从第一状态切换到第二状态的时间极短且在第二状态 附近的保持时间长于或等于一个扫描周期，这样可使得当扫描到该逐 点控制 TN盒的最后一行时， 该逐点控制 TN盒的第一行被改变为第 二状态的液晶还远远未回复到第一状态。以下以图 5所示的逐点控制 TN盒为例说明如何使第 5行的 53、 、 a5S、 a56、 57， 第 6行的^、
«64、 a65、 a66、 «67 ' 第 7行的 ί¾、 <374、 «75、 <376、 «77 > 第 8行的 ί½、 aiA、 aS5 aS6、 asi内的扭曲液晶都为第二状态， 同时使该逐点控制 TN盒的其余部位的扭曲液晶都为第一状态。 对于图 5所示的逐点控 制 盒， 则可在初始时使电极 al至 a8保持同样的输入电压 t/。， 在 逐行扫描时， 依次从 al开始对每行进行扫描且扫描输入电压为 在扫描第 5行的同一时刻向电极 a3、 电极 a4、 电极 a5、 电极 a6和电 极 a7输入脉冲电压 [/2，使这些电极与第 5行电极 b5的交叠区域上下 电势差 （即 C/2 - ）大于等于^。 其中， ^为该逐点控制 TN盒中 采用的扭曲液晶改变状态所对应的阈值电压， （ - ) 小于 且 ( U2 ~U0 ) 小于 U!h。 则此时 a53、 «54、 a55、 a56、 a57中的扭曲液晶同 时从第一状态迅速切换到笫二状态。 同样地， 在扫描第 6行的同一时 刻向电极 a3、 电极 a4、 电极 a5、 电极 a6和电极 a7输入脉冲电压 /2 , 使 、 a6i , 65、 ¾、 67的两端电势差大于等于 则 α63、 "ΰ4、 α65、 a 7中的扭曲液晶同时从第一状态迅速切换到第二状态； 在扫描 第 Ί行的同一时刻向电极 a3、 电极 a4、 电极 a5、 电极 a6和电极 a7 输入脉沖电压 t/2，使^、 ^ 4、 ^75、 ^76、 ^77的两端电势差大于等于^， 则 、 。74、 a15、 a16、 ^中的扭曲液晶同时从第一状悉迅速切换到第 二状态； 在扫描第 8行的同一时刻向电极 a3、 电极 a4、 电极 a5、 电 极 a6和电极 a7输入脉冲电压 t/2并使 、 i¾、 aS5 ¾、 87中的扭曲 液晶同时从第一状态迅速切换到第二状态。 由于扫描频率很高， 因此 当扫描到第 8行时, £½、 "54、 aS5、 as6、 α5Ί、 <¾、 α64、 65、 «66、 α67、 和 αΊΊ所对应的液晶几乎还没从第二状态向第一状态 转变， 即： 可认为此时 α53、 α54、 α55 , α56 , α57、 。63、 a64、 α65、 α66 , α 、 α73、 α7 , αΊ5 , ¾和《77中的扭曲液晶仍处于第二状态， 且该逐 点控制 ΤΝ盒的其它像素显示区内的扭曲液晶处于第一状态。 此外， 在新的扫描周期到来时，若需要使上一个扫描周期中已从第一状态转 变为第二状态的像素显示区 aij内的液晶转变回第一状态 ,则需要在本 次扫描周期内扫描到第 i行时， 根据此时 内液晶的状态， 同时向第 j列电极输入适当的脉冲电压，以使 内的液晶的长轴迅速反向旋转， 即使其迅速转变回第一状态。 显然， 若采用上述扫描方式， 就可以对 该逐点控制 TN盒的各像素显示区的扭曲液晶的状态进行切换控制， 实现与 TFT型的逐点控制 TN盒等同的切换显示功能。所述第一配向 层的配向方向和第二配向层的配向方向是否需要垂直，可以根据具体 的应用要求而定。
显然，本发明实施例提供的上述逐点控制 TN盒不仅可以实现逐 点切换控制， 此外， 由于第一电极和第二电极采用波浪线方式设置， 且各波浪带状电极信号从带状电极一端输入而无需在各电极之间布 线以单独控制各像素点两端电极电压， 因此， 该逐点控制 TN盒中无 需使用黑矩阵，显示区域内的电极宽度可最大化，且可进行全区域控 制， 相对于 TFT型的 TN盒， 这种逐点控制 TN盒的有效显示面积得 以扩大， 开口率得到显著提高， 且电极之间无亮线， 显示质量得以改 善。上述实施例中波浪带状电极的形状仅仅是示意性的， 可以灵活变 动，而且第一电极和第二电极其中之一为波浪形带状电极也会改善电 极边缘产生亮线的情况。第一电极或第二电极也可以不必均位于一个 平面， 比如第一电极的其中一部分电极位于第一透明基板的一面， 另 一部分电极位于第一透明基板的另一面；第二电极的其中一部分电极 位于第二透明基板的一面， 另一部分电极位于第二透明基板的另一 面。 而且电极可以位于透明基板上与配向层相对的一面。
本发明实施例还提供一种采用上述逐点控制 TN盒作为切换装置 的 2D- 3D立体显示装置， 如图 6所示， 沿光传播方向， 该装置包括： 提供图像的显示面板 61、 本发明所提供的逐点控制 TN盒 62、 单折 射透镜阵列 63和与单折射透镜阵列 63吻合的 斤射透镜阵列 64。 此外， 图 6所示的 2D- 3D立体显示装置还包括： 用于控制所述逐点 控制 TN盒 62的各电极电压的控制模块 65。
所述显示面板 61用于提供偏振方向与传播方向相互垂直的第一 线偏振光。 当所述显示面板 6 的出射光为非线性偏振光时， 需要在 显示面板 61和所述逐点控制 TN盒 62之间添加线偏振片以使所述线 偏振片出射第一线偏振光。
所述逐点控制 TN盒 62中靠近所述显示面板 61的一侧的控制层 中配向层的配向方向与入射的第一线偏振光的偏振方向相互平行。该 逐点控制 T 盒 62用于在所述控制模块 65的控制下使入射的第一线 偏振光直接透射或将所述第一线偏振光转换为偏振方向与其垂直的 第二线偏振光。 以下为方便说明， 设逐点控制 TN盒 62中第一控制 层比第二控制层接近所述显示面板 61 , 第一配向层的配向方向与所 述第一线偏振光的偏振方向相同。 逐点控制 TN盒 62具有与显示面 板 61像素阵列对应的像素显示区阵列。
所述单折射透镜阵列 63的折射率为 ,双折射透 4竟阵列 64具有 寻常光折射率《。和非寻常光折射率《β , 且" i u：^。 所述双折射透 镜阵列 64的透镜光轴方向与所述第一线偏振光的偏振方向相同， 图 6中双箭头所示为该双折射透镜阵列 64的透镜光轴方向。 值得说明的是， 图 6中是为了标明显示面板 61提供的第一线偏 振光的偏振状态以及第一线偏振光经逐点控制 TN盒 62后的偏振状 态而使显示面板 61、逐点控制 TN盒 62和单折射透镜阵列 63之间分 别具有一定间距， 具体实施时， 所述显示面板 61、 逐点控制 TN盒 62和单折射透镜阵列 63可以紧密接触放置。 此外， 图 6中仅是示意 性画出了控制模块 65和逐点控制 TN盒 62的连接关系 , 实际上控制 模块 65对所述逐点控制 TN盒 62内的各电极单独控制。
以下对图 6所示的 2D-3D立体显示装置的 4条成像光路图进行 说明， 其中上两条第一线偏振光最后发生折射， 下两条第一线偏振光 直接透射， 下面具体说明它们的原理。
从图 6中可以看出， 由于需要对上两条第一线偏振光进行 3D显 示， 控制模块 65使上两奈第一线偏振光所对应的逐点控制 TN盒 62 的像素显示区内的液晶工作于第二状态，因此入射的上两条第一线偏 振光保持原偏振特性穿过该逐点控制 盒 62,接着穿过单折射透镜 阵列 63并入射到默折射透镜阵列 64, 此时由于入射的第一线偏振光 的偏振方向与所述双折射透镜阵列 64光轴方向平行， 因此双折射透 镜阵列 64对于该第一线偏振光线的折射率为; 由于单折射透镜阵 列 63的折射率 ηι大于 ， 因此入射于所述双折射透镜阵列 64的第一 线偏振光在单折射透镜阵列 63和双折射透镜阵列 64的交界面上发生 折射， 且所述双折射透镜阵列 64的光学效杲表现为凸透镜。 这种情 况下, 该 2D-3D立体显示装置可以将最终出射的两奈光线分别传播 到人眼的左眼和右眼，使人眼看到 3D立体图像， 即谅 2D-3D立体显 示装置将上两条光线采用 3D方式显示。
对于入射于所述逐点控制 TN盒 62的下两条第一线偏振光， 控 制模块 65使下两条第一线偏振光所对应的逐点控制 TN盒 62的像素 显示区内的液晶工作于第一状态，因此入射的下两条第一线偏振光通 过该逐点控制 TN盒 62后偏振方向被旋转 90度， 变为第二线偏振光 出射； 随后所述第二线偏振光经所述单折射透镜阵列 63射至所述双 折射透镜阵列 64, 此时由于入射的第二线偏振光的偏振方向与所述 双折射透镜阵列 64的光轴方向（即第一线偏振光的偏振方向）垂直， 因此所述双折射透镜阵列 64相对于该第二线偏振光的折射率为 , 由于单折射透镜阵列 63 的折射率 等于 , 即此时单折射透镜阵列 63的折射率与双折射透镜阵列 64的折射率相同， 因此该第二线偏振 光在所述单折射透镜阵列 63和双折射透镜阵列 64的界面处不发生折 射， 第二线偏振光直线通过所述 折射透镜阵列 64。 这种情况下， 该 2D-3D立体显示装置将图 6所示的下两条第一线偏振光耒用 2D方 式显示。 - 图 6所示的 2D-3D立体显示装置中的单折射透镜阵列 63和双折 射透镜阵列 64还可以有别的组合方式，例如 CN201126495中所提到 的其它单折射透镜阵列和汉折射透镜阵列的组合方式， 在此不再详 述。
将本发明实施例提供的逐点控制 TN盒用于 2D-3D立体显示装置 中，可以实现对图像显示面板的单个像素的独立控制，也可以对图像 显示面板的多个像素进行控制， 不仅实现简单、控制灵活， 而且能够 显著提高 2D-3D立体显示装置的显示质量。
上述的具体实施方式仅仅是示意性的， 而不是限制性的， 本领域 的技术人员在本方法的启示下，在不脱离本方法宗旨和权利要求所保 护的范围情况下，还可以作出很多变形，这些均属于本发明的保护范 围之内。
