Description
技术领域
本发明是有关于液晶显示技术领域,特别是有关于一种液晶面板及其像素结构。
背景技术
在薄膜晶体管液晶屏幕的生产中,主要有两种配向方法:磨擦(rubbing)配向及光配向。磨擦配向会产生静电和颗粒的污染,光配向是一种非接触式的配向技术,利用紫外光照射在特殊材质的配向膜上,以使配向膜的高分子自动导向到紫外光照射的角度,故不会有使用磨擦配向方法所产生的问题。
然而,当使用光配向方法时,每个像素单元内部会形成特殊形状的暗纹。请参照图1,图1是像素单元10内的暗纹的示意图。这种暗纹大致包含位于像素单元10的中间部的十字型暗纹12,以及从十字型暗纹12的各个端点121出发,沿着像素单元10的直边或横边平行延伸的直边暗纹14及横边暗纹16,也就是整个像素单元10中会有类以“卐”或“卍”状的暗线带。然而,这些暗纹会影响像素的开口率,导致薄膜晶体管液晶屏幕的显示效果不佳。
故,有必要提供一种液晶面板及其像素结构,以解决现有技术所存在的问题。
发明内容
有鉴于此,本发明提供一种液晶面板及其像素结构,能提升像素结构的开口率。
为达成本发明的前述目的,本发明一实施例提供一种像素结构,其中所述像素结构包含:多个像素单元、多个黑色矩阵、多个数据线、多个公共电极及多个闸线。所述多个像素单元以阵列方式相邻设置,所述多个像素单元各具有进行一光配向时形成的:一横暗纹、一直暗纹、一第一横边暗纹、一第二横边暗纹、一第一直边暗纹及一第二直边暗纹。所述横暗纹平行所述像素单元的一横边。所述直暗纹平行所述像素单元的一直边,且所述直暗纹与所述横暗纹交错形成一个十字形。所述第一横边暗纹从所述直暗纹的一端朝平行所述横暗纹的一方向延伸。所述第二横边暗纹从所述直暗纹的另一端朝平行所述横暗纹的方向延伸,其中所述第二横边暗纹的延伸方向与所述第一横边暗纹的延伸方向相反。所述第一直边暗纹从所述横暗纹的一端朝平行所述直暗纹的一方向延伸。所述第二直边暗纹,从所述横暗纹的另一端朝平行所述直暗纹的方向延伸,其中所述第二直边暗纹的延伸方向与所述第一直边暗纹的延伸方向相反。所述多个黑色矩阵沿着所述多个像素单元的第一直边暗纹及第二直边暗纹重叠设置。所述多个数据线沿着所述多个像素单元的第一直边暗纹及第二直边暗纹重叠设置。所述多个公共电极沿着所述多个像素单元中的一部分的第一横边暗纹及第二横边暗纹重叠设置。所述多个闸线沿着所述多个像素单元中的另一部分的第一横边暗纹及第二横边暗纹重叠设置,其中所述多个闸线与所述多个公共电极交替的平行排列。
在本发明的一实施例中,每一所述像素单元的横暗纹及直暗纹是交错位在所述像素单元的一中心处。
在本发明的一实施例中,所述多个像素单元包含沿着所述像素单元的直边的一方向相邻设置的多个主像素单元及多个副像素单元。
在本发明的一实施例中,所述多个像素单元包含沿着所述像素单元的横边的一方向依序排列的多个红色像素单元、多个绿色像素单元及多个蓝色像素单元。
在本发明的一实施例中,每一所述像素单元的第一直边暗纹及第二直边暗纹的长度均为所述像素单元的直边的一半。
在本发明的一实施例中,每一所述像素单元的第一横边暗纹及第二横边暗纹的长度均为所述像素单元的横边的一半。
在本发明的一实施例中,所述多个黑色矩阵、所述多个数据线、所述多个公共电极及所述多个闸线皆是呈Z字形垂直拐弯设置。
在本发明的一实施例中,更包含多个光间隔物,位于所述多个像素单元之间。
在本发明的一实施例中,所述多个光间隔物沿着所述多个黑色矩阵及所述多个数据线重叠设置。
再者,本发明另一实施例提供一种液晶面板,其中所述液晶面板包含︰一阵列基板、一对向基板以及位在所述阵列基板及所述对向基板之间的一液晶层,所述阵列基板上具有一彩色光阻层,且所述彩色光阻层中设置有如上述的像素结构。
与现有技术相比较,本发明的像素结构及液晶面板透过将黑色矩阵、数据线、公共电极、闸线等元件重叠设置于暗纹处,以增加像素结构其他地方的开口率,进而提升液晶面板的显示效果。特别是,能增加COA(ColorfilteronArray)型液晶面板在阵列基板的彩色光阻层中的像素结构的开口率,及其液晶面板的显示效果。
为让本发明的上述内容能更明显易懂,下文特举优选实施例,并配合所附图式,作详细说明如下:

具体实施方式
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的特定实施例。再者,本发明所提到的方向用语,例如上、下、顶、底、前、后、左、右、内、外、侧面、周围、中央、水平、横向、垂直、纵向、轴向、径向、最上层或最下层等,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。
请参照图2所示,图2是本发明实施例的像素结构20的示意图。所述像素结构20包含多个像素单元22、多个黑色矩阵(blackmatrix)24、多个数据线(dataline)26、多个公共电极28及多个闸线(gateline)30。所述多个像素单元22系以阵列方式相邻设置。
当所述多个像素单元22进行一光配向,以使一配向膜(未绘示)的高分子自动导向到紫外光照射的角度时,所述多个像素单元22各会形成一横暗纹32、一直暗纹34、一第一横边暗纹36、一第二横边暗纹38、一第一直边暗纹40、一第二直边暗纹42。所述横暗纹32平行所述像素单元20的一横边44。所述直暗纹34平行所述像素单元22的一直边46,且所述直暗纹34与所述横暗纹32交错形成一个十字形。在一实施例中,每一所述像素单元22的横暗纹32及直暗纹34是交错位在所述像素单元22的一中心处48。所述第一横边暗纹36从所述直暗纹34的一端朝平行所述横暗纹32的一方向延伸。所述第二横边暗纹38从所述直暗纹34的另一端朝平行所述横暗纹32的方向延伸,其中所述第二横边暗纹38的延伸方向与所述第一横边暗纹36的延伸方向相反。在一实施例中,如图2所示,所述第一横边暗纹36朝左方延伸,所述第二横边暗纹38朝右方延伸。在另一实施例中,每一所述像素单元22的第一横边暗纹36及第二横边暗纹38的长度均为所述像素单元22的横边44的一半。所述第一直边暗纹40从所述横暗纹32的一端朝平行所述直暗纹34的一方向延伸。所述第二直边暗纹42从所述横暗纹32的另一端朝平行所述直暗纹34的方向延伸,其中所述第二直边暗纹42的延伸方向与所述第一直边暗纹40的延伸方向相反。在一实施例中,如图2所示,所述第一直边暗纹40朝上方延伸,所述第二直边暗纹42朝下方延伸。在一实施例中,每一所述像素单元22的第一直边暗纹40及第二直边暗纹42的长度均为所述像素单元12的直边46的一半。
所述多个黑色矩阵24及所述多个数据线26皆沿着所述多个像素单元22的第一直边暗纹40及第二直边暗纹42重叠设置。由于所述多个黑色矩阵24及所述多个数据线26会影响开口率,所以将这些元件的设置位置与所述第一直边暗纹40及所述第二直边暗纹42的位置重叠,以使所述像素结构10位于其他位置的开口率得以增加。在一实施例中,所述多个黑色矩阵24及所述多个数据线26呈Z字形垂直拐弯设置。
所述多个公共电极28沿着所述多个像素单元22中的一部分的第一横边暗纹36及第二横边暗纹38重叠设置。所述多个闸线30沿着所述多个像素单元12中的另一部分的第一横边暗纹36及第二横边暗纹38重叠设置,其中所述多个闸线30与所述多个公共电极28交替的平行排列。举例而言,在图2上方的第二横边暗纹38是与所述公共电极28重叠设置;位在图2中间的第一横边暗纹36及第二横边暗纹38是与所述闸线30重叠设置;及位在图2下方的第一横边暗纹36及第二横边暗纹38是与所述公共电极28重叠设置。换言之,所述多个闸线30与所述多个公共电极28交替的平行排列,且与所述第一横边暗纹36及所述第二横边暗纹38重叠。由于所述多个公共电极28及所述多个闸线30会影响开口率,所以将这些元件的设置位置与所述第一横边暗纹36及所述第二横边暗纹38的位置重叠,以使所述像素结构10位于其他位置的开口率得以增加。在一实施例中,所述多个闸线30与所述多个公共电极28呈Z字形垂直拐弯设置。
请一并参照图2及3所示,图3是本发明另一实施例的液晶面板50的剖面示意图。本发明的液晶面板50属于COA(ColorfilteronArray)型的液晶面板,也就是采用将彩色光阻层制作于薄膜晶体管阵列基板上的技术。所述液晶面板50包含一阵列基板52、一对向基板54以及位在所述阵列基板52及所述对向基板54之间的一液晶层56。所述阵列基板52上具有一彩色光阻层58,且所述彩色光阻层58中设置有前述的像素结构10。在一实施例中,在所述阵列基板52的内表面上设有所述像素单元22、所述数据线26、一部分的所述公共电极28及所述闸线30(未绘示于图3中),其中所述像素单元22是位在所述阵列基板52上的一彩色光阻层58中。在又一实施例中,在所述对向基板54的内表面上设有所述黑色矩阵24及另一部分的所述公共电极28。在另一实施例中,所述液晶面板50还包含有多个光间隔物60,位于所述液晶层56中,用以分隔出不同的液晶区域。由上方视角观之,所述多个光间隔物60位于所述多个像素单元12之间的交界处。在又一实施例中,在所述液晶面板50的俯视方向上,所述多个光间隔物60沿着所述多个黑色矩阵24及所述多个数据线26重叠设置。从图2及3中可知,在所述液晶面板50的俯视方向上,会影响开口率的多个器件,例如所述黑色矩阵24、所述数据线26、所述公共电极28、所述闸线30及所述光间隔物60均是与暗纹重叠设置,所以可以增加所述液晶面板50的像素结构12的其他处的开口率,进而提升所述液晶面板50的显示效果。特别是,能增加COA(ColorfilteronArray)型液晶面板在阵列基板52的彩色光阻层58中的像素结构12的开口率,及其液晶面板的显示效果。在一实施例中,所述阵列基板52上还可设置扫描线72、二绝缘层74及76、半导体层78、钝化层80及像素电极82等所述液晶面板50所需要的元件。
请参照图4,图4是本发明另一实施例的像素结构10A的多个像素单元12A的示意图。在一实施例中,所述多个像素单元12A可以包含沿着所述像素单元12A的直边46的一方向相邻设置的多个主像素单元83多个副像素单元84,其中所述副像素单元64可以辅助所述主像素单元83对于颜色的表现程度。
