 背景技术
现行三维显示器技术有主动式快门眼镜，固定式偏光眼镜等需要佩戴眼镜的技术，以及柱状透镜及固定式光栅等不需要佩戴眼镜的技术。
采用固定式偏光眼镜技术的显示器在光出射面的外侧布置1/4波片，将显示器出射的线偏振光变成圆偏振光。再通过一片有固定图案的相位差1/2波长（180度）的相位延迟片，使得到达左眼和右眼的光信号分别经过相差半个波长的相位延迟后，形成左旋偏光和右旋偏光到达观察者。观察者佩戴的固定式偏光眼镜，左眼和右眼分别可以通过左旋偏光和右旋偏光，因此可以形成三维影像。固定式偏光眼镜技术由于需要在一个画面中同时显示左眼和右眼的信息，因此平面显示器所能表示的画面信息减少一半，这是固定式偏光眼镜技术最大的缺点。同时偏光眼镜技术会有一个方向上的视角限制。另外，在制程上，图形化的延迟片需要与显示器做精准的对位，制程比较复杂，并且对良率会有一定的影响，从而导致制造成本较高。

 本发明的最佳实施方式
为让本发明上述目的、特征及优点更明显易懂，下文特举本发明较佳实施例，并配合附图，作详细说明。
实施例一
如图1所示，为本发明提供的三维显示器的光路原理示意图，该三维显示器包括显示器1和液晶盒模块2。液晶盒模块2放置在显示器1和观察者之间。显示器1包含偏光板，液晶盒模块2包括液晶盒21和1/4波长相位延迟片22。显示器1中的双箭头线为显示器1的偏光板的透射方向。液晶盒21的上半部分把显示器发出的对应同一个完整显示画面的光的相位延迟0波长，液晶盒21的下半部分把显示器发出的对应同一个完整显示画面的光的相位延迟1/2波长，形成对应同一个完整显示画面的左旋偏光和右旋偏光。观察者佩戴的偏光眼镜3的左侧镜片附有1/4波片，右侧镜片附有-1/4波片，左眼和右眼分别可以通过左旋偏光和右旋偏光，形成三维影像。
如图2所示，本发明的第一较佳实施例三维显示器示意图。其中，显示器1为液晶显示器，显示器1包含偏光板。液晶盒模块2包括铁电型液晶（Ferroelectric Liquid Crystal）盒21和1/4波长相位延迟片22。铁电型液晶盒21具有1/2波长相位延迟，铁电型液晶盒21和1/4波长相位延迟片22贴合于液晶显示器1的出光面。液晶显示器1的偏光板吸收轴和铁电型液晶盒2的液晶分子的配向方向平行，1/4波长相位延迟片22和液晶显示器1的偏光板吸收轴夹45度角。铁电型液晶盒21上施加有电场以改变偏光方向。
当光经过铁电型液晶盒21时，在没有外加电压时偏光方向不变。如果对铁电型液晶盒21加适当大小的电压，铁电型液晶盒21的液晶分子的排列方向改变到另一个稳态，铁电型液晶盒21的1/2波长相位延迟会使偏光方向改变90度。1/4波长相位延迟片22和液晶显示器1的偏光板吸收轴平行，液晶显示器1发出的光经过铁电型液晶盒21后再经过1/4波长相位延迟片22，会因为偏光方向不同而分别形成左旋偏光和右旋偏光。然后分别由左右眼对应的偏光眼镜3来检偏，从而分离出左右眼图像，再由大脑将这两幅图像合成为具有三维效果的影像。
实施例二
本实施例的三维显示器的结构和实施例一的三维显示器的结构基本相同。本实施例和实施例一的区别在于，液晶显示器1的偏光板吸收轴和铁电型液晶盒21的液晶分子的配向方向夹22.5度角。铁电型液晶盒21的相位延迟为1/2波长， 1/4波长相位延迟片22和液晶显示器1的偏光板吸收轴平行。铁电型液晶盒21上施加有电场以改变偏光方向。
在没有外加电压时，铁电型液晶盒21对液晶显示器1的偏光板吸收轴的夹角为22.5度；对铁电型液晶盒21加适当大小的电压时，铁电型液晶盒21对液晶显示器1的偏光板吸收轴的夹角为-22.5度。铁电型液晶盒21的相位延迟分别使偏光方向分别改变45及-45度。1/4波长相位延迟片22和液晶显示器1的偏光板吸收轴平行，液晶显示器1发出的光经过铁电型液晶盒21后再经过1/4波长相位延迟片22，会因为偏光方向不同而分别形成左旋偏光和右旋偏光。然后分别由左右眼对应的偏光眼镜3来检偏，从而分离出左右眼图像，再由大脑将这两幅图像合成为具有三维效果的影像。
实施例三
如图3所示，为本发明第三较佳实施例三维液晶显示的示意图，该三维显示器包括显示器1和液晶盒模块2，显示器1包含偏光板。液晶盒模块2把显示器发出的对应同一个完整显示画面的光的相位延迟，并形成对应同一个完整显示画面的左旋偏光和右旋偏光。显示器1为液晶显示器。液晶盒模块2包含反铁电型液晶（Anti-Ferroelectric Liquid Crystal）盒21，反铁电型液晶盒21具有1/4波长相位延迟。反铁电型液晶盒21贴合于显示器1的出光面，显示器1的偏光板吸收轴和反铁电型液晶盒21的液晶分子的配向方向平行。反铁电型液晶盒21上施加有电场以改变偏光方向。当光经过反铁电型液晶盒21时，在没有外加电压时，相位延迟为零，偏光方向不变；如果对反铁电型液晶盒21加适当大小的正向电压，反铁电型液晶盒21的相位延迟会形成1/4波长的相位延迟；如果对反铁电型液晶盒21加适当大小的反向电压，反铁电型液晶盒21的相位延迟会形成-1/4波长的相位延迟。也就是说，反铁电型液晶盒21的三个稳态间的相位延迟分别为1/4及-1/4波长。显示器1发出的光经过反铁电型液晶盒21后，会因为相位延迟不同而分别形成左旋偏光和右旋偏光。然后分别由左右眼对应的偏光眼镜3来检偏，从而分离出左右眼图像，再由大脑将这两幅图像合成为具有三维效果的影像。
实施例四
本实施例揭示一种三维显示器的制作方法，包含如下步骤：提供显示器，显示器包含偏光板；在显示器的出光方向布置可将显示器发出的对应同一个完整显示画面的光的相位延迟，并形成对应同一个完整显示画面的左旋偏光和右旋偏光的液晶盒模块。
在本实施例中，液晶盒模块采用如下步骤制得：提供铁电型液晶盒，铁电型液晶盒具有1/2波长相位延迟；提供1/4波长相位延迟片；将铁电型液晶盒和1/4波长相位延迟片贴合于显示器的出光面，使得显示器的偏光板吸收轴和铁电型液晶盒的配向方向平行，1/4波长相位延迟片和显示器的偏光板吸收轴平行；在铁电型液晶盒上施加电场以改变偏光方向。
实施例五
本实施例揭示另一种三维显示器的制作方法，本实施例的三维显示器的制作方法和实施例四的三维显示器的制作方法基本相同。本实施例的和实施例四的区别在于，显示器的偏光板吸收轴和铁电型液晶盒的配向方向夹22.5度角，1/4波长相位延迟片和显示器的偏光板吸收轴平行。
实施例六
在本实施例中，液晶盒模块采用如下步骤制得：提供反铁电型液晶盒，反铁电型液晶盒具有1/4波长相位延迟；反铁电型液晶盒贴合于显示器的出光面，使得显示器的偏光板吸收轴和反铁电型液晶盒的配向方向平行；在反铁电型液晶盒上施加电场以改变偏光方向。
本发明并不限定铁电型液晶盒和1/4波长相位延迟片在显示器的出光面的贴合次序。
进一步的，还可以将液晶显示器的画面更新速度提高至两倍，使得左右眼的偏光眼睛获得更多的画面信息，画面更加流畅。
进一步的，还可以将铁电型液晶或反铁电型液晶与1/4波长相位延迟片整合成一个光学复合片，具体可通过粘接或者晶体分层生长实现，使用整合后的光学复合片在贴合到液晶显示器的出光面将减少工时，从而降低制造成本。
本发明的技术方案利用铁电型液晶盒或反铁电型液晶盒作为快速相位调制器，通过施加电场改变铁电型液晶盒或反铁电型液晶盒的液晶分子的排列方向，利用铁电型液晶盒或反铁电型液晶盒的相位延迟改变偏光方向，再经过1/4波长相位延迟片分别形成左旋偏光和右旋偏光，配合左右眼不同方向偏光眼镜，以达到三维显示的功能。本发明的技术方案避免了画面解析度降低一半的问题。
本发明采用的铁电型液晶和反铁电型液晶具有广视角的特性，本发明的三维显示器的视角不会受到影像。另外，由于铁电型液晶和反铁电型液晶的应答速度比向列型液晶的应答速度快，可以低于1毫秒以下，对三维显示器的亮度的影响比快门式三维显示器的低。图4A和4B为本发明的第三较佳实施例采用的反铁电型液晶的响应时间的实测结果。图4A表明了本发明的第三较佳实施例采用的反铁电型液晶在10伏外加电压下的响应曲线。图4B表明了本发明的第三较佳实施例采用的反铁电型液晶在10伏、15伏和20伏外加电压下的响应时间。在10伏外加电压下，实施例三采用的反铁电型液晶的开启时间（Response time, Ton）为0.792毫秒，关闭时间（Response time, Toff）为0.79毫秒。当外加电压升高到20伏时，第三较佳实施例采用的反铁电型液晶的开启时间（Response time, Ton）为0.753毫秒，关闭时间（Response time, Toff）为0.74毫秒。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
