Description

可在2D和3D模式之间切换的显示器及其控制方法 【技术领域】
本发明涉及显示技术领域，特别是涉及一种可在2D和3D模式之间切换的显示器及其控制方法。
【背景技术】
近年来，随着平板显示技术与相关材料领域技术的不断进步，3D显示成为人们关注的焦点，尤其是裸眼3D由于用户不需要穿戴辅助设备即可以观看到3D效果，备受关注。
目前，较为常见的两种方式为光屏障式3D技术和柱状透镜技术。
光屏障式3D技术的实现方法是使用一个开关液晶屏、偏振膜和高分子液晶层，利用液晶层和偏振膜制造出一系列方向为90°的垂直条纹。这些条纹宽几十微米，通过它们的光就形成了垂直的细条栅模式，称之为“视差障壁”。而该技术正是利用了安置在背光模块及LCD面板间的视差障壁，在立体显示模式下，应该由左眼看到的图像显示在液晶屏上时，不透明的条纹会遮挡右眼；同理，应该由右眼看到的图像显示在液晶屏上时，不透明的条纹会遮挡左眼，通过将左眼和右眼的可视画面分开，使观者看到3D影像。这种技术的优点是在成本上比较有优势，不过采用这种技术的屏幕亮度偏低。
柱状透镜技术也被称为微柱透镜3D技术，使液晶屏的像平面位于透镜的焦平面上，这样在每个柱透镜下面的图像的像素被分成几个子像素，这样透镜就能以不同的方向投影每个子像素。于是双眼从不同的角度观看显示屏，就看到不同的子像素。柱状透镜技术并不会像光屏障式那样影响屏幕亮度，所以显示效果要好。然而，如果透镜焦距(focal length)为f，透镜节距(lens pitch)为p，透镜与显示器之间的间距为g，影像成像的位置位于透镜前面L距离处，假设显示器的解析度足够高的情况下，此时成像的解析度为：R＝L/2p，解析度单位为空 间频率(1/rad)；观看视角(viewing angle)为：θ＝2arctan(p/2g)，因此现有技术存在的技术问题是：当透镜节距p增大时，观看视角θ变大，但是成像解析度R变小，很难同时改善集成成像显示器的解析度R和观看视角θ。
传统方法用于改善解析度而又不降低观看视角的方法是采用移动透镜(lens moving)的方式：透镜朝一个方向移动一个距离(该距离小于一个lens pitch)，显示屏显示相对应的元素图像(EI)，由于人眼的暂留效应，人会看到解析度增强的3D影像，并且此时观看视角不会有变化；透镜阵列移动的距离s必须小于透镜阵列的lens pitch p，一般设置p/s＝n为整数，如果透镜只在水平方向上进行移动，那么在水平方向上的解析度便可以获得提高(提高为改善前的n倍)；如果透镜移动的方向与水平方向成一定夹角f(透镜斜着移动)，那么所成的像在水平和垂直方向上的解析度都会有相应提高，在水平方向提高为n×cosf倍，在垂直方向上提高为n×sinf倍。传统方法采用机械移动的方式，实际实现起来非常困难，而且机械移动的速度较快很难控制，lens array机械移动过程中与显示器的精确对位问题也比较难解决。
因此，需要提供一种可在2D和3D模式之间切换的显示器及其控制方法，以解决上述技术问题。

【具体实施方式】
下面结合附图和实施例对本发明进行详细的说明。
请参阅图1，图1是本发明可在2D和3D模式之间切换的显示器的俯视结构示意图；图2是本发明优选实施例的可在2D和3D模式之间切换的显示器在图1中预定方向A-A上的横截面图。
在本实施例中，显示器包括依次层叠设置的第一透镜面板11、第一显示面板12、第二透镜面板13以及第二显示面板14。优选地，第一透镜面板11、第一显示面板12、第二透镜面板13以及第二显示面板14相互平行设置，且由上至下依次为第一透镜面板11、第一显示面板12、第二透镜面板13以及第二显示面板14。
第一透镜面板11和第二透镜面板13分别包括沿预定方向A-A排列的第一透镜单元111和第二透镜单元131，第一透镜面板11包括多个沿预定方向A-A排列的第一透镜单元111，而第二透镜面板13包括多个沿预定方向A-A排列的第二透镜单元131。
第一透镜单元111和第二透镜单元131能够在对入射光线产生折射的聚焦状态和不对入射光线产生折射的非聚焦状态之间进行切换，其中第一透镜单元 111和第二透镜单元131沿预定方向A-A彼此错开，优选地，第一透镜单元111和第二透镜单元131沿预定方向A-A的节距p相同，且第一透镜单元111和第二透镜单元131沿预定方向的错开量s为节距p的一半。
优选地，第一透镜面板11包括相对设置的第一透明基板112、第二透明基板113以及封装在第一透明基板112与第二透明基板113之间的第一液晶层114，第二透镜面板13包括相对设置的第三透明基板132、第四透明基板133以及封装在第三透明基板132与第四透明基板133之间的第二液晶层134，第一透明基板112由多个沿预定方向A-A的截面呈弧形的第一曲面结构1121连接形成，第三透明基板132由多个沿预定方向A-A的截面呈弧形的第二曲面结构1321连接形成，第一曲面结构1121和第二曲面结构1321在预定方向A-A上错开设置。值得注意的是，在本实施例中，第一液晶层114封装在第一透明基板112和第二透明基板113之间，在其他实施例中，第一透镜面板11也可以仅包括第一透明基板112，而不包括第二透明基板113，在这种情形下，第一液晶层114封装在第一显示面板12与第一透明基板112之间，同理，第二液晶层134也可以直接封装在第二显示面板14与第三透明基板132之间，即第二透镜面板13也可以仅包括第三透明基板132，而不包括第四透明基板133。
优选地，第一曲面结构1121和第二曲面结构1321沿预定方向A-A的宽度p相等，且第一曲面结构1121和第二曲面结构1321沿预定方向的错开量s为宽度p的一半。
优选地，显示器进一步包括控制单元(图未示)，控制单元在3D模式下控制显示器交替地在第一状态和第二状态下进行切换，其中在第一状态下，第一显示面板12处于显示状态，第一透镜面板11上的第一透镜单元111处于聚焦状态，以使第一显示面板12所显示的元素图像经第一透镜单元111聚焦后投射至观察者；在第二状态，第一显示面板12处于透明状态，第一透镜面板11上的第一透镜单元111处于非聚焦状态，第二显示面板14处于显示状态，第二透镜面板13上的第二透镜单元131处于聚焦状态，以使第二显示面板14所显示的元素图 像经第二透镜单元131聚焦且经第一显示面板12和第一透镜面板11透射后投射至观察者。由于第一透镜单元111和第二透镜单元131沿预定方向的错开量s为节距p的一半，显示器在水平方向的解析度可以提高p/s倍，优选的情况下可以提高一倍。
优选地，控制单元在2D模式下控制第一显示面板12处于显示状态，第一透镜面板11上的第一透镜单元111处于非聚焦状态，或者控制第一显示面板12处于透明状态，第二显示面板14处于显示状态，第一透镜面板11上的第一透镜单元111和第二透镜面板13上的第二透镜单元131均处于非聚焦状态。
第一液晶层114和第二液晶层134均包括多个液晶分子，第一液晶层114包括多个液晶分子1141，第二液晶层134包括多个液晶分子1341。
优选地，控制单元用于控制液晶分子1141、1341旋转，其中，液晶分子1141、1341的第一轴向X旋转为平行于第一显示面板12时，对应的第一透镜单元111或第二透镜单元131处于聚焦状态，液晶分子1141、1341的第一轴向X旋转为垂直于第一显示面板12时，对应的第一透镜单元1141或第二透镜单元1341处于非聚焦状态。
请参阅图3，图3是图2中液晶分子的长轴与短轴示意图。液晶分子1141、1341的第一轴向X折射率ne大于第一透明基板112和第三透明基板132的折射率no，液晶分子1141、1341的第二轴向Y折射率no等于第一透明基板112和第三透明基板132的折射率no，液晶分子1141、1341的第一轴向X折射率ne指的是光线方向垂直与第一轴向X时液晶分子1141、1341对光线的折射率，液晶分子1141、1341的第二轴向Y折射率no指的是光线方向垂直与第二轴向Y时液晶分子1141、1341对光线的折射率液晶分子1141、1341有长轴X和短轴Y之分，在本实施例中，优选地，液晶分子1141、1341的第一轴向X为其长轴X，第二轴向Y为其短轴Y。在这两个轴的方向上的折射率是不相等的，假设长轴X的折射率为ne，短轴Y的折射率为no，我们以ne＞no为例进行说明。图3中仅以液晶分子1141进行说明，可以理解的是液晶分子1341与液晶分子1141 类似。
请进一步参阅图4和图5，图4是本发明优选实施例的显示器在其第一透镜单元或第二透镜单元在非聚焦状态下的液晶分子倒向示意图，图5是本发明优选实施例的显示器在其第一透镜单元或第二透镜单元在聚焦状态下的液晶分子倒向示意图。本实施例以正型液晶分子为例(负型液晶类似)，图4为控制单元没有加电压(在第一透明基板和第二透明基板之间不产生电场，类似的，或者是在第三透明基板和第四透明基板之间不产生电场)的情况，此时液晶分子1141、1341长轴X在垂直于第一显示面板12的方向排列，当入射偏振光的偏振态为如图4所示水平方向B-B时，此时第一液晶层114或第二液晶层134对于入射光ss的折射率为no，而第一透明基板112或第三透明基板132的折射率同样为no，由于折射率在入射光ss的传播方向上没有发生变化，入射光ss不会发生折射，第一透镜单元111或第二透镜单元131不形成透镜聚焦，即第一透镜单元111或第二透镜单元131处于非聚焦状态；图5为控制单元加电压(在第一透明基板和第二透明基板之间产生电场，类似的，或者是在第三透明基板和第四透明基板之间产生电场)的情况，此时液晶分子长轴X在平行于第一显示面板12的方向排列，当入射偏振光的偏振态为如图5所示水平方向B-B时，此时第一液晶层114或者第二液晶层134对于入射光ss的折射率为ne，而第一透明基板112或第三透明基板132的折射率为no，而ne＞no，此时光会发生折射，且产生透镜聚焦效果，即第一透镜单元111或第二透镜单元131处于聚焦状态。上图4和图5中仅以液晶分子1141为例进行说明可以理解的是对应的液晶分子1341与之类似。
请进一步参阅图6，图6是本发明另一实施例的可在2D和3D模式之间切换的显示器在图1中预定方向A-A上的横截面图。本实施例与上述实施例区别在于，显示器进一步包括第一封装盒15以及第二封装盒16，第一封装盒15位于第一透镜面板11和第一显示面板12之间，第二封装盒16位于第二透镜面板13和第二显示面板14之间，控制单元通过控制第一封装盒15和第二封装盒16 以分别控制入射到第一透镜单元111和第二透镜单元131的偏正光的偏振态，从而分别控制第一透镜单元111和第二透镜单元131在聚焦状态和非聚焦状态之间切换。优选地，第一封装盒15和第二封装盒16为TN cell，且与第一显示面板12和第二显示面板14平行。即在本实施例中，液晶分子1141、1341不需要旋转即可实现第一透镜单元111和第二透镜单元131在聚焦状态和非聚焦状态之间切换，优选地，液晶分子1141、1341的长轴X沿平行于第一显示面板12的方向排列。
请参阅图7，图7是本发明可在2D和3D模式之间切换的显示器的控制方法的优选实施例的流程图。在本实施例中，该控制方法采用上文描述的显示器实现，控制方法包括以下3D显示的步骤：
步骤S11：控制显示器交替地在第一状态和第二状态下进行切换，其中在第一状态下，第一显示面板处于显示状态，第一透镜面板上的第一透镜单元处于聚焦状态，以使第一显示面板所显示的元素图像经第一透镜单元聚焦后投射至观察者，在第二状态，第一显示面板处于透明状态，第一透镜面板上的第一透镜单元处于非聚焦状态，第二显示面板处于显示状态，第二透镜面板上的第二透镜单元处于聚焦状态，以使第二显示面板所显示的元素图像经第二透镜单元聚焦且经第一显示面板和第一透镜面板透射后投射至观察者。
控制方法还包括2D显示的步骤：
步骤S12：控制第一显示面板处于显示状态，第一透镜面板上的第一透镜单元处于非聚焦状态，或者控制第一显示面板处于透明状态，第二显示面板处于显示状态，第一透镜面板上的第一透镜单元和第二透镜面板上的第二透镜单元均处于非聚焦状态。
可以理解的是步骤S11和S12先后顺序可以相互调换。
本发明通过设置第一透镜面板和第二透镜面板分别包括沿预定方向排列的第一透镜单元和第二透镜单元，且通过控制第一透镜单元和第二透镜单元能够在对入射光线产生折射的聚焦状态和不对入射光线产生折射的非聚焦状态之间 进行切换，且设置第一透镜单元和第二透镜单元沿预定方向彼此错开，能够较好的同时改善显示器的解析度和观看视角
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
