Description

液晶显示设备及立体影像显示设备 技术领域
本发明涉及一种液晶显示设备，尤其涉及一种支持薄膜式偏光(film pattern retarded, FPR)技术的立体影像显示设备。
 背景技术
液晶显示器(Liquid Crystal Display，LCD)轻、薄、低耗电等优点，被广泛应用于计算机、移动电话及个人数字助理等现代化信息设备。一般来说，液晶显示器包含液晶显示面板及背光模块(backlight module)，由于液晶显示面板自身不会发光，因此液晶显示器必须仰赖背光模块内的光源来发出光线。由背光模块内的光源所发出的光线，经过液晶显示面板的液晶，藉由液晶的转向，来调整传递至使用者的光线强度，进而输出影像。
随着科技发展，二维的显示技术已经无法满足观赏者的观赏需求；因此，三维显示技术遂应运而生，三维显示技术藉由双眼视差，以允许观赏者观赏到立体影像，让观赏者彷佛有身历其境的感觉。
请参阅图1，图1绘示现有立体影像显示设备100和圆偏眼镜130的示意图。立体影像显示设备100包含背光模块110、显示面板140、偏光片(polarizing plate)130以及1/4波长阵列波片120。
显示面板140包含由数个像素组成的像素阵列141、彩色滤光片142以及位于像素阵列141以及彩色滤光片142之间的液晶层(未绘示)。显示面板140上的像素阵列141包含多条左眼像素行单元(left-eye pixel line unit) L与多条右眼像素行单元(right-eye pixel line unit) R。多条右眼像素行单元R与该多条左眼像素行单元L是交替排列，其中左眼像素行单元L是用来依据左眼信号显示左眼影像，右眼像素行单元R是用来依据右眼信号显示右眼影像。彩色滤光片142则包含用来显示红、蓝、绿三原色的滤光单元146以及位于任两个相邻滤光单元146之间的黑色阵列(Black matrix)层142b。当光线通过红、蓝、绿三原色的滤光单元146后，就会显示出对应的颜色，但是光线将不会通过黑色阵列层142b。
由背光模块110所产生出来的光线，穿过滤光单元146的偏光片144后成为线偏振光。偏光片110的透射光方向与水平方向A呈90度的夹角。
接着，由偏光片144射出的线偏振光会射入1/4波长阵列波片(λ/4 pattern retarder plate)120。1/4波长阵列波片120具有多条第一延迟片121和多条第二延迟片122。多条第一延迟片121和多条第二延迟片122是交替排列，第一延迟片121的光轴方向与水平方向A的夹角为45度，第二延迟片122的光轴方向与水平方向A的夹角为135度。从右眼像素行单元R射出的光线经过偏光片144以及第一延迟片121后，会变为右旋圆偏振光；从左眼像素行单元L射出的光线经过偏光片144以及第二延迟片122后，会变为左旋圆偏振光。
最后，右旋圆偏振光及左旋圆偏振光会入射至圆偏眼镜130。圆偏眼镜130由第一延迟片121、第二延迟片122和偏光片133组成。左右眼镜片的1/4波长波片121、122的光轴方向分别为45度和135度，而偏光片133的透射光方向都为垂直于水平方向A(亦即90度)。因此，形成的左旋圆偏振光可以透过左眼镜片，而右旋圆偏振光可以透过右眼镜片。在本实施例中，由于左旋圆偏振光是对应到左眼信号，右旋圆偏振光是对应到右眼信号，因此观察者戴上圆偏眼镜130，双眼就可以分别看到不同的左眼影像与右眼影像，并在人脑感知成看到了3D影像。
然而，在观赏者观赏三维影像时，左(或右)眼影像也会有少部分进入右(或左)眼通道，这样便会产生影像串扰(Crosstalk)，这影像串扰的大小会直接影响到三维的观赏效果。
业界对于串扰的防止，一般会采用黑色阵列层143来遮挡上下两行的像素。请参阅图2，其绘示图1像素阵列141与彩色滤光片142组装后，黑色阵列层143与像素相对位置的示意图。为了简化图式，图2所示的像素阵列141仅包含两行像素，然而，像素阵列141实际上包含更多像素。此外，图2亦仅绘示出部分的黑色阵列层143(仅绘示出像素210与像素220交界处)。黑色阵列层143位于所有像素的交界处，用来阻挡光线通过两像素210、220之间。
黑色阵列层143用来遮挡分别对应上下两行的像素210与像素220，然而，这样的架构有其缺点。对于像素210内的主像素212与次像素211或像素220内的主像素222与次像素221来说，黑色阵列层143覆盖主像素212的宽度A1小于覆盖次像素211的宽度A2，所以黑色阵列层143覆盖主像素212的面积小于覆盖次像素211的面积，这样导致同一像素210内的主像素212和次像素211显示的定义区域(domain)不对称，进而造成视角偏差的问题。
因此，业界须开发一种新的立体影像显示设备，以解决上述问题。

 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1绘示现有立体影像显示设备和圆偏眼镜的示意图。
图2绘示图1像素阵列与彩色滤光片组装后，黑色阵列层与像素相对位置的示意图。
图3绘示本发明立体影像显示设备的示意图。
图4为图3的局部放大图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施之特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「顶」、「底」、「水平」、「垂直」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参阅图3，图3绘示了本发明立体影像显示设备300的示意图。立体影像显示设备300包含对应第一行的第一像素310、对应第二行的第二像素320、薄膜晶体管313、323、以及黑色阵列层330。第二像素320与第一像素310为相邻像素，也就是说，第二像素320与第一像素310对应相同的数据线(以数据线方向排列)，但却分别对应两相邻的扫描线(未绘示于图中)；因此，第一像素310与第二像素320是用来显示对应观赏者不同眼的影像，举例来说，第一像素310可用来显示左(右)眼影像，而第二像素320便对应地用来显示右(左)眼影像。
立体影像显示设备300另包含有数条扫描线340与数条数据线350，这些扫描线340与数据线350相互垂直。此外，图3所示的立体影像显示设备300仅包含两行像素，然而，立体影像显示设备300实包含更多像素，如此的相对应变化，亦属本发明的范畴。另外，图3亦仅绘示出部分的黑色阵列层330(仅绘示出第一像素310与第二像素320交界的地方)。黑色阵列层330位于所有像素的交界处，用来阻挡光线通过两像素310、320之间。
第一像素310包含第一主像素311以及第一次像素312，第二像素320包含第二主像素321以及第二次像素322。主像素与次像素共享同一薄膜晶体管。于本实施例中，第一主像素311以及第一次像素312共享薄膜晶体管313，而第二主像素321以及第二次像素322共享薄膜晶体管323；也就是说，当薄膜晶体管313接收到所对应的扫描线340传来的扫描信号而开启时，将数据线350的数据信号传递至第一像素310所包含的第一主像素311与第一次像素312，当薄膜晶体管323接收到所对应的扫描线340传来的扫描信号而开启时，将数据线350的数据信号传递至第二像素320所包含的第二主像素321与第二次像素322。
此外，于本实施例中，主像素与次像素的排列方式有所不同，如图3所示，第一主像素311与第一次像素312并非如现有的架构，而是以水平方向(朝扫描线340延伸方向)排列。
上述的排列方式可以避免前述的问题。黑色阵列层330亦覆盖于第一像素310与第二像素320之上，以用来遮挡分别对应上下两行的第一像素310与第二像素320。然而，于本实施例中，黑色阵列层330会均匀地遮盖第一像素310所包含的第一主像素311与第一次像素312以及第二像素320所包含的第二主像素321与第二次像素322。对于第一像素310内的第一主像素311与第一次像素312来说，由于第一主像素311与第一次像素312已经以水平方向排列，因此两者被黑色阵列层330覆盖的宽度A3、A4均相同；而对于第二像素320内的第二主像素321与第二次像素322来说，其被黑色阵列层330覆盖的宽度A3、A4亦相同。
请参阅图4，图4为图3的局部放大图。图4仅绘示出第一像素310与黑色阵列层330，以说明彼此的相对关系。黑色阵列层330所覆盖的区域，对于第一像素310内的第一主像素311与第一次像素312来说，其宽度(A3+A4)都是相同的；同理可推知，黑色阵列层330所覆盖的区域，对于第二像素320内的第二主像素321与第二次像素322来说，其宽度(A3+A4)都是相同的。所以同一像素210内的主像素212和次像素211的定义区域的比例是相同的，因此，本发明液晶显示设备便不会有显示区域不对称的状况，进而也解决了现有技术中视角偏差的问题。
相较于现有技术，本发明提供一种液晶显示设备，其藉由重新排列每一像素的主像素与次像素位置，使得各像素被黑色阵列层遮挡之后，不会有显示区域不对称的问题，进而解决视角偏差的缺点。
综上所述，虽然本发明已以较佳实施例揭露如上，但该较佳实施例并非用以限制本发明，该领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
