Description

立体影像显示系统 技术领域
本专利申请涉及一种立体影像显示技术，且特别是涉及一种立体影像显示系统。
 背景技术
图1绘示一种现有的立体显示器工作原理的示意图。现有的立体显示器是采用相位延迟（pattern retarder）技术，配合偏光眼镜来呈现出立体影像。如图1所示，在显示器的显示面板（未图示）一侧设置有一线偏振片10，而在彩色滤光片基板（未图示）一侧设置有λ/4阵列波片12。从显示器的背光模组（未图示）发出的光线，经过线偏振片10后会被极化形成线偏振光。线偏振片10的光轴与水平方向H成90°夹角，故只有偏振方向为垂直方向的光线能够通过线偏振片10，也就是说，通过线偏振片10后的光线为垂直偏振光。再者，λ/4阵列波片12的光轴方向有两种，一种为光轴方向与水平方向成45°夹角，另一种光轴方向与水平方向成135°夹角，这两种光轴沿着垂直方向呈交替排列，如图1所示。因此，来自线偏振片10的垂直偏振光经过λ/4阵列波片12后会同时形成右旋圆偏振光和左旋圆偏振光。
来自λ/4阵列波片12的左旋圆偏振光可以通过偏光眼镜14右眼镜片而进到观赏者的右眼，左旋圆偏振光因会被左眼镜片吸收而不会进到观赏者左眼，而来自λ/4阵列波片12的右旋圆偏振光可以通过偏光眼镜14左眼镜片而进到观赏者的右眼，右旋圆偏振光因会被右眼镜片吸收而不会进到观赏者右眼，如此人的左右眼接收到不同画面而能感受到影像立体效果。
图2绘示一种现有采用1/4λ相位延迟膜片21实现3D显示系统的示意图。如图2所示，因应立体影像的显示，彩色滤光片23上可划分成显示左眼影像的左色块区23L和显示右眼影像的右色块区23R，左色块区23L以及右色块区23R设置有黑色矩阵（black matrix, BM）22，以防止暗态漏光，左色块区23L以及右色块区23R分别对应于相位延迟膜片21的一相位延迟区21L以及另一相位延迟区21R。当影像信号从左色块区23L边界的黑色矩阵通过玻璃基板24后，接着进入所述相位延迟膜片21的另一相位延迟区21R的位置时，发射出大于θ角的光线，导致来自左色块区23L的光线会进入偏光眼镜14的相位延迟膜片142而被右眼镜片的右眼看到，或是自右色块区23R的光线会进入偏光眼镜14的相位延迟膜片141而被左眼镜片的左眼看到，从而造成影像串扰(cross-talk)。因此需要发展一种新式的立体影像显示器，以解决上述当液晶显示器产生影像信息串扰的问题。

如图3所示，液晶显示面板36，用于显示影像的面板，其由多个像素列，每个像素列包括多个像素区。在本实施例中，液晶显示面板36的入光侧以及出光侧分别设置第一偏光片34以及第二偏光片38，亦即第一偏光片34设置于背光板32与液晶显示面板36之间，第二偏光片38设置于液晶显示面板36与相位延迟膜40之间。第一偏光片34使来自背光板32的背光，使其偏振化。第二偏光片38使通过液晶面板的光线沿着透射方向V形成垂直偏振化光线，所述透射方向V与水平方向成90度。
如图3所示，液晶显示面板36包括薄膜晶体管阵列基板36a、液晶层36b以及彩色滤光层36c。液晶层36b设置在薄膜晶体管阵列基板36a和彩色滤光层36c之间。如图3所示，薄膜晶体管阵列基板36a设置于所述第一偏光片34和液晶层36b之间，薄膜电晶体阵列基板36a上设置的薄膜电晶体可控制液晶层36b内之液晶分子的偏转进而改变光线偏极化的角度。
如图3所示，彩色滤光层36c设置于所述薄膜晶体管阵列基板36a的一侧并且位于液晶层36b与相位延迟膜40之间，彩色滤光层36c用以使偏振光线产生色彩的变化。如图3所示，相位延迟膜40设置于所述第二偏光片38的一侧，穿过所述第二偏光片38的垂直偏振光通过相位延迟膜40以形成左旋圆偏振光和右旋圆偏振光。
偏光眼镜50是由左右偏振镜片53、54以及其上贴附的偏振膜片51、52所组成。
图4A是本专利申请实施例中液晶显示面板36在一图框周期的驱动方式的平面示意图；图4B是本专利申请实施例中液晶显示面板36在下一个图框周期的驱动方式的平面示意图；图5是本专利申请实施例中液晶显示面板36的驱动周期的对应时序图，水平方向H表示穿出图示所在的平面。如图4A以及图4B所示，在液晶显示面板36中，薄膜晶体管阵列基板36a包括多个第一像素列361和多个第二像素列362沿着所述透射方向V互相交替平行排列，透射方向V与水平方向H成90°夹角，其中在一图框周期T1内，所述多个第一像素列361输入对应的第一灰阶电压显示对应的第一图像画面，所述多个第二像素列362输入一第一黑画面电压显示一第一黑画面，在下一个图框周期T2内，所述多个第二像素列362输入对应的第二灰阶电压显示对应的第二图像画面，所述多个第一像素列361输入一第二黑画面电压显示一第二黑画面。
所述图框周期T1定义为所述第一图像画面与所述第二图像画面的显示时间间隔。所述下一个图框周期T2定义为所述第二图像画面与所述第一图像画面的显示时间间隔。在一实施例中，所述图框周期T1以及下一个图框周期T2小于或是等于8.3毫秒(ms)。所述图框周期T1以及下一个图框周期T2的倒数定义为图框速率，所述图框速率大于或是等于120赫兹(Hz)。但是不限于此。在一实施例中，图框周期T3等于图框周期T1。
如图5所示，相位延迟膜40包括对应于所述多个第一像素列361的第一相位延迟区L和对应于所述多个第二像素列362的第二相位延迟区R。换言之，相位延迟膜40具有两个不同的偏振方向，可经由适当设计，使得进入到观赏者左眼的影像在第一相位延迟区L具有第一偏振方向，而进入到观赏者右眼的影像在第二相位延迟区R具有第二偏振方向，而且偏光眼镜50设计成左镜片只允许具第一偏振方向的左眼影像通过，右镜片只允许具第二偏振方向的右眼影像通过。依此方式，当观赏者戴上偏光眼镜30时，左眼只会看到显示器提供给左眼的影像，右眼只会看到显示器提供给右眼的影像，可改善影像串扰的问题，观赏者即能感知到三维的立体影像。
继续参考图3、图4A以及图4B，所述薄膜晶体管阵列基板36接收所述偏振光并且以一图框速率沿着所述透射方向V依序交替驱动每条第一像素列361与每条第二像素列362。换言之，所述薄膜晶体管阵列基板36目前的一图框周期之内驱动每条第一像素列361，并且在下一个图框周期之内驱动每条第二像素列362。具体来说，薄膜晶体管阵列基板36以线扫描方式将数据写入第一像素列361与第二像素列362。举例来说，显示面板30的闸极驱动器30g由上而下以所述图框速率先驱动一显示画面中全部的第一像素列361，使源极驱动器30s将显示数据写入各个第一像素列361的第一像素区36a1中，如图4A以及图4B所示的红色(red, R)、绿色(green, G)、绿色(blue, B)像素电极；接着闸极驱动器由上而下以所述图框速率驱动所述显示画面中全部的第二像素列362，使源极驱动器将显示数据写入各个第二像素列362的第二像素区36b1中，如图4A以及图4B所示的R、G、B像素电极。
在所述图框周期T1内，所述第一黑画面的每个第二像素列362形成一第一插黑线363，以遮蔽通过所述第一偏光片34并且相对于每个第二像素列362的偏振光，亦即互相间隔排列的多条第一插黑线363形成第一黑画面。所述第一插黑线363与所述第一图像画面的每个第一像素列361互相交错排列。所述第一插黑线364对应所述第二相位延迟区R。在所述下一个图框周期T2内，所述第二黑画面的每个第一像素列361形成一第二插黑线364，以遮蔽通过所述第一偏光片34并且相对于每个第一像素列361的偏振光，亦即互相间隔排列的多条第二插黑线364形成第二黑画面。所述第二插黑线364与所述第二图像画面的每个第二像素列362互相交错排列。所述第二插黑线364对应所述第一相位延迟区L。在所述图框周期T1内，对应于所述第一图像画面的光线通过所述第二偏光片38以及所述相位延迟膜40的第一相位延迟区L，以形成左旋圆偏振光，在所述下一个图框周期T2内，对应于所述第二图像画面的光线通过所述第二偏光片38以及所述相位延迟膜40的第二相位延迟区R，以形成右旋圆偏振光。换言之，在第二相位延迟区R产生的左眼影像不会与对应于第一相位延迟区L的右眼影像重迭。在第一相位延迟区L产生的左眼影像不会与对应于第二相位延迟区R右眼影像重迭。
所述液晶显示面板还包括彩色滤光层36c，设置于所述第二偏光片38的另一侧并且位于所述相位延迟膜40的相对异侧，所述彩色滤光层36c包括第一滤光单元以及第二滤光单元，分别相对应所述第一相位延迟区R以及第二相位延迟区L。
综上所述，本专利申请的立体影像显示系统，通过液晶显示面板的图框速率与像素的插黑线的对应配置，将左眼影像以及右眼影像分别在不同的图框周期输出，使左眼影像以及右眼影像不会互相重迭串扰，可以增加立体影像显示系统的垂直视角，解决影像信息串扰(crosstalk)的问题。
虽然本专利申请已用较佳实施例揭露如上，然其并非用以限定本专利申请，本专利申请所属技术领域中具有通常知识者，在不脱离本专利申请的精神和范围内，当可作各种的更动与润饰，因此本专利申请的保护范围当视后附的权利要求范围所界定者为准。
