Description

采用半源极驱动结构的3D显示装置
【技术领域】
本发明是有关于3D显像技术,特别是有关于一种采用半源极驱动结构的3D显示装置。
【背景技术】
因为人的双眼具有一定间距的关系,双眼看到的物体的方向并非完全一致。因此,3D显示器利用人类的两眼视差,分别提供给两眼不同影像而产生立体效果。
参考图1所示,现有一种3D显像***是通过在液晶显示面板的光出射面上设置由一图案化的二分之一相位延迟层90及一四分之一波长相位延迟层91所构成的相位延迟片来向观看者输送偏振方向不同的影像,同时,观看者配戴偏振眼镜7,使其左眼接收单一偏振方向的影像,而右眼则接收另一偏振方向的影像,进而在大脑合成立体影像。一般来说,所述3D显像***的液晶显示面板是将其奇数列(或偶数列)的像素列所显示的影像作为左眼输入影像,而其它像素列则作为右眼输入影像。
如图1所示,所述3D显像***的液晶显示面板的影像会先通过偏光片转为线性偏振影像80。所述线性偏振影像80接着经过图案化的二分之一相位延迟片90之后,光线会分成两组偏振方向互相垂直的线性偏振影像81。所述两组线性偏振影像81经过所述四分之一波长相位延迟片91之后,即会输出包括左圆偏振影像及右圆偏振影像的影像82,以作为左眼输入影像与右眼输入影像。观看者配戴的偏振眼镜7的镜片71、72由四分之一波片及偏光片构成。所述包括左圆偏振影像及右圆偏振影像的影像82会先通过所述镜片71、72的四分之一波片而转成线性偏振影像,接着再经过所述镜片71、72的偏光片后,分别到达左、右眼。由于所述镜片71、72的偏光片具有不同偏振方向,使得使用者的左眼只能看到左眼输入影像,而右眼只能看到右眼输入影像,因而可达到三维影像的效果。
请参考图2所示,图2是现有3D显像***的液晶显示面板贴附相位延迟片的局部示意图。现有3D显像***的液晶显示面板包括多条栅极线51、多条与栅极线51交错的资料线50以及所述栅极线51与资料线50定义的像素区。所述像素区设有薄膜晶体管及像素电极52。所述像素区可分成多个像素列。现有3D显像***的相位延迟片60具有多个第一相位延迟区域60A及多个第二相位延迟区域60B,其中所述第一相位延迟区域60A与所述第二相位延迟区域60B是交错排列并且具有不同的液晶配向。而所述相位延迟片的第一相位延迟区域60A及第二相位延迟区域60B的交界处会位于相邻的像素列之间,通过相邻的像素列之间的黑色矩阵53来遮蔽第一相位延迟区域60A及第二相位延迟区域60B的交界处。
请参考图3所示,由于源极驱动电路的成本较栅极驱动电路高,为了源极驱动电路的使用,现有另一种3D显像***是采用半源极驱动电路(half source driver,HSD)的像素驱动结构,也就是将源极驱动电路的资料线50减半,而将栅极驱动电路的栅极线51加倍成为两条栅极线51a、51b,如此便能在相同像素数目下,降低源极驱动电路的资料线数目而减低成本。
然而,如图3所示,在半源极驱动电路的像素驱动结构中,当其中一像素电极52所连接的薄膜晶体管位于其上侧时,相邻的像素电极52连接的薄膜晶体管会位于所述像素电极52的下侧。由于像素区空间固定的关系,位于同一列上的相邻像素电极52的出光位置将会有所不同。为了遮蔽栅极线51、资料线50以及薄膜晶体管,黑色矩阵53会对应薄膜晶体管的位置而在栅极线51的两侧形成周期性的凸起,如图4所示。如此一来,在贴附如图2所示的相位延迟片60时,同一像素列中的相邻的像素电极52的透光量将会不一致,造成3D显像***的色偏问题。
故,有必要提供一种采用半源极驱动结构的3D显示装置,以解决现有技术所存在的问题。

请参考图5所示,图5是本发明采用半源极驱动结构的3D显示装置一较佳实施例的相位延迟片对应贴附在液晶显示面板的局部示意图。本发明的3D显示装置包括一液晶显示面板及一相位延迟片10。所述液晶显示面板包括多条栅极线20、多条资料线21,所述栅极线20与所述资料线21交错构成多个像素区,其中每一栅极线20对应每一像素区皆弯折成一拱形的容置区210,且每一像素区设有至少一开关单元25及至少一像素电极22,所述至少一开关元件25设于所述拱形的容置区210内并连接所述栅极线20及所述像素电极22,且优选为薄膜晶体管。所述相位延迟片是设于所述液晶面板的外侧。

由于本发明是采用半源极驱动结构的3D显示装置,位在同一列的像素单元中,所述第二资料线21b除了连接其中一像素单元的第二开关元件25b之外,还连接相邻像素单元的第一开关元件25a。
一般来说,所述液晶显示面板(图未示出)的主要结构包括第一基板、第二基板、液晶层、第一偏光片以及第二偏光片。第一基板可为为具有彩色滤光片(Color Filter,CF)的玻璃基板或其它材质的基板,所述彩色滤光片包括不同颜色的光刻胶单元。所述像素阵列则是设置于所述第二基板,也就是说,所述栅极线20、所述资料线21、所述开关元件25、所述像素电极22是设于第二基板上,所述栅极线21和资料线20定义的像素区即对应所述彩色滤光片的光刻胶单元。所述第一基板上的彩色滤光片还包括如图5所示的黑色矩阵23,用以对应遮蔽所述所述栅极线20、所述资料线21及所述开关元件25。所述液晶层是形成于第一基板与第二基板之间。所述第一偏光片是设置所述第一基板的外侧(亦即为第一基板的出光侧)。第二偏光片是设置第二基板的外侧(亦即为第二基板的入光侧)。所述3D显示装置更包含一背光模组,设于第二偏光片的外侧,以提供光源入射通过所述第二偏光片。而所述相位延迟片10是设置在所述第一偏光片的外表面。

本发明的3D显示装置的动作原理如下述:
所述液晶显示面板的第一偏光片会将液晶显示面板的出射光影像转成线偏振光影像;所述线偏振光影像接着通过所述相位延迟片10,其中通过所述第一相位延迟单元列10A的线偏振光影像会转换成左圆偏振光影像(或右圆偏振光影像);通过所述第二相位延迟单元列10B会转换成右圆偏振光影像(或左圆偏振光影像)。使用者可搭配圆偏眼镜来使其双眼分别接收左圆偏振光影像和右圆偏振光影像,进而产生立体视觉的效果。
再者,由于栅极线形成的容置区可容纳开关元件以及储存电容,位于同一列的相邻像素区的像素电极可相互对齐,而不必对应开关元件及储存电容的位置调整,亦即出光位置可维持一致,同时黑色矩阵23对应栅极线51的两侧也可不必形成周期性的凸起。因此,可避免相位延迟片发生贴附误差时所产生的色偏问题。
由上述说明可知,相较于现有技术的缺失,本发明让栅极线弯折形成容置区以容纳开关元件,使得同一列的相邻像素区的像素电极的出光位置可维持一致,进而可避免相位延迟片发生贴附误差时所产生的色偏问题。
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。
