Description

阵列基板、显示面板和显示装置
技术领域
本实用新型涉及显示技术领域,具体涉及一种阵列基板、显示面板和显示装置。
背景技术
在液晶显示装置的制作过程中需要进行摩擦工序,摩擦工序是指用裹有尼龙布或棉布的摩擦辊,以一定方向和力度对阵列基板和彩膜基板上的取向膜表面进行摩擦,从而形成能让液晶有定向排列和预倾角的沟槽。
图1和图2为现有的显示面板中像素区的两种排列方式示意图,其中,对于ADS产品,取向方向沿图1和图2中的竖直方向。这就会导致以下问题:对于图1这种像素区规则排列为多行多列的显示面板而言,对其阵列基板或彩膜基板进行摩擦取向时,摩擦辊的一部分基本上一直对像素区P进行取向,另一部分始终对像素区P之间的间隔区进行取向,而由于基板上像素区P与间隔区的结构不同,导致像素区P和间隔区之间存在一定的段差,从而使得摩擦辊上对应于像素区P的部分和对应于间隔区的部分受力不同,进而导致长时间摩擦取向后,摩擦辊上的绒布形态分布不均,取向过程中容易出现取向不良。而对于图2这种像素区交错排列的显示面板而言,对其阵列基板或彩膜基板进行摩擦取向时,摩擦辊的一部分周期性地与间隔区和像素区接触,取向辊受力的均匀性比对图1的显示面板取向时稍有改善,但是长时间使用后还是会对取向结果造成不良影响。
实用新型内容
本实用新型旨在至少解决现有技术中存在的技术问题之一,提出了一种阵列基板、显示面板和显示装置,以减少取向过程中的取向不良。
为了解决上述技术问题之一,本实用新型提供一种阵列基板,包括多条栅线、多条数据线以及设置在所述栅线所在层和所述数据线所在层上方的第一取向层,所述栅线和所述数据线交叉设置,以将所述阵列基板划分为多个像素区,所述像素区的长度方向与所述第一取向层的取向方向之间成锐角。
优选地,多个像素区排列为多行,所述栅线沿行方向延伸,所述取向方向与所述行方向垂直。
优选地,所述像素区的长度方向与所述第一取向层的取向方向之间的夹角在10°~25°之间。
优选地,任意一条数据线中,该数据线的位于同一行中的相邻两像素区之间的部分的延伸方向与所述像素区的长度方向相同。
优选地,所述像素区内设置有像素电极,所述像素电极包括沿所述取向方向排列的至少两个子电极部,每个所述子电极部上均形成有多个狭缝,同一像素电极中的相邻两个子电极部上的狭缝的延伸方向不同。
优选地,每个所述子电极部上的狭缝的延伸方向与所述取向方向之间的夹角相同。
优选地,每个所述子电极部上的狭缝的延伸方向与所述取向方向之间的夹角均在5°~20°之间。
相应地,本实用新型还提供一种显示面板,包括阵列基板和与所述阵列基板对盒设置的对盒基板,所述阵列基板为本实用新型提供的上述阵列基板,所述对盒基板上朝向所述阵列基板的一侧设置有第二取向层,所述第二取向层的取向方向与所述像素区的长度方向成锐角。
优选地,多个像素区排列为多行,所述对盒基板上还设置有与所述像素区一一对应的色阻块,所述色阻块的颜色种类为n,n为大于等于3的整数;
在同一行中,依次排列的n个色阻块的颜色互不相同;
依次排列的n行色阻块中,位置对应的n个色阻块颜色互不相同。
相应地,本实用新型还提供一种显示装置,包括本实用新型提供的上述显示面板。
在本实用新型中,由于本实用新型的阵列基板的像素区的长度方向与阵列基板上第一取向层的取向方向成锐角,因此,在对阵列基板上的第一取向层进行摩擦取向时,摩擦辊与间隔区短暂接触后很快就会与像素区接触,从而使得摩擦辊基本上一直处于与像素区接触的状态,从而使摩擦辊表面不同区域受力更均匀,表面绒毛形态分布更均匀,减少长时间使用后出现的取向不良现象,提高显示产品的质量。相类似地,对盒基板上的第二取向层的取向方向也与像素区的长度方向成锐角,在对第二取向层进行取向时,摩擦辊表面的不同区域受力也更加均匀,防止长时间使用后产生取向不良的现象。另外,像素区的像素电极采用双畴结构,能够减少色偏现象;对盒基板上依次排列的n行色阻块中,位置对应的色阻块的颜色不同,从而提高色域。

具体实施方式
以下结合附图对本实用新型的具体实施方式进行详细说明。应当理解的是,此处所描述的具体实施方式仅用于说明和解释本实用新型,并不用于限制本实用新型。
作为本实用新型的一方面,提供一种阵列基板,如图3所示,包括多条栅线10、多条数据线20以及设置在栅线10所在层和所述数据线20所在层上方的第一取向层,栅线10和数据线20交叉设置,以将所述阵列基板划分为多个像素区P,如图3和图4所示,像素区P的长度方向与所述第一取向层的取向方向之间成锐角。
其中,像素区P内设置有像素电极30、薄膜晶体管等结构,像素区P与数据线20、栅线10所在区域(即,像素区P之间的间隔区)在阵列基板的厚度方向上形成段差。当像素区P的长度方向或宽度方向与取向方向一致时,在对第一取向层进行摩擦取向过程中,摩擦辊上部分区域始终与像素区P接触摩擦,另一部分区域始终与间隔区接触摩擦,而导致摩擦辊受力不均;即使相邻两行的像素区交错设置,也会因为摩擦辊的一部分区域周期性的与像素区和间隔区交替设置,而导致长时间取向后摩擦辊受力不均的情况。
在本实用新型中,由于像素区P的长度方向与取向方向之间成锐角,因此,在对阵列基板上的第一取向层进行摩擦取向时,摩擦辊与间隔区短暂接触后很快就会与像素区P接触,从而使得摩擦辊基本上一直处于与像素区P接触的状态,从而使摩擦辊表面不同区域受力更均匀,表面绒毛形态分布更均匀,减少长时间使用后出现的取向不良现象,提高显示产品的质量。
其中,所述取向方向可以沿所述阵列基板的长度方向或者宽度方向。在本实用新型中,如图3所示,多个像素区P排列为多行,栅线10沿行方向(具体可以为阵列基板的长度方向)延伸,所述取向方向与所述行方向垂直。
具体地,像素区P的长度方向与所述第一取向层的取向方向之间的夹角在10°~25°之间,进一步具体地,如图4所示,该夹角为15°,从而减少摩擦辊与间隔区的接触时间,同时防止像素区P过于倾斜而影响显示效果。
另外,数据线20的延伸方向总体上与像素区P的长度方向一致,如图3所示,数据线20总体上是从左上方向右下方倾斜的,任意一条数据线20中,该数据线20的位于同一行中的相邻两像素区P之间的部分的延伸方向与像素区P的长度方向相同。而数据线20位于相邻两行之间的部分可以与像素区P的长度方向相同,以使得整条数据线20成直线状;也可以如图3中所示,数据线20位于相邻两行之间的部分与像素区P的长度方向不同,使得数据线20成弯折状,从而使相邻两行像素区P位置对应的两个像素区P交错。
进一步地,结合图3和图5所示,像素区P内设置有像素电极30,像素电极30包括沿所述取向方向排列的至少两个子电极部31,每个子电极部31上均形成有多个狭缝32,同一像素电极30中的相邻两个子电极部31上的狭缝32的延伸方向不同。优选地,每个子电极部31上的狭缝32的延伸方向与所述取向方向之间的夹角相同。如图5所示,像素电极30包括两个子电极部31,两个子电极部31的狭缝32的延伸方向不同,但与取向方向之间的夹角相同,也就是说,两个子电极部31上的狭缝32是上下对称的,从而形成双畴结构。与单畴结构相比,由于在单畴结构的显示面板中,从显示面板的一侧观看时,观看方向与液晶分子的长轴方向一致,另一侧观看时,观看方向与液晶分子的短轴方向一致,从而导致不同方向看到的显示效果不同,发生色偏现象;而对于采用双畴结构的显示面板,初始状态下液晶分子的长轴方向与取向方向一致,在通电进行显示时,两个子电极部31的分别沿图5中的单向箭头方向偏转,从而在显示面板的任意一侧观看时,观看方向与一部分液晶分子的长轴方向一致,同时还与另一部分液晶分子的短轴方向一致,进而改善色偏。
其中,每个子电极部31上的狭缝32的延伸方向与所述取向方向之间的夹角均在5°~20°之间,从而保证液晶分子在偏转时出现杂乱,改善显示效果。其中,该夹角具体可以为7°。
作为本实用新型的另一方面,提供一种显示面板,该显示面板包括本实用新型提供的上述阵列基板和与所述阵列基板对盒设置的对盒基板,所述对盒基板上朝向所述阵列基板的一侧设置有第二取向层,第二取向层的取向方向与像素区P的长度方向成锐角。本实用新型的显示面板尤其适用于高级超维场转换模式(Advanced Super Dimension Switch,简称ADS)和高开口率(High Opening rate)H-ADS模式的产品中,即,所述第二取向层的取向方向与所述第一取向层的取向方向相同。第二取向层与所述对盒基板之间还可以设置有黑矩阵50,如图6所示,黑矩阵50与每相邻两个像素区P之间的间隔区对应,以对间隔区的栅线10、数据线20进行遮挡。
和阵列基板上的第一取向层的取向过程相同地,尽管对盒基板上对应于像素区P和间隔区的部分在厚度方向上有段差,但是,由于第二取向层与像素区P的长度方向也成锐角,因此,摩擦辊对第二取向层取向时,与间隔区部分接触时间很短,基本一直处于与像素区P的第二取向层接触的状态,提高摩擦辊受力的均匀性,改善取向效果。
进一步地,如图6所示,所述对盒基板上还设置有与像素区P一一对应的色阻块40,像素区P排列为多行,色阻块40也相应地排成多行,色阻块40的颜色种类为n,n为大于等于3的整数。其中,在同一行中,依次排列的n个色阻块40的颜色互不相同,如图6中,色阻块40的颜色包括红R、绿G、蓝B三种,红绿蓝三种颜色的色阻块40轮流排列;并且,为了提高显示面板的色域,依次排列的n行色阻块40中,位置对应的n个色阻块40的颜色互不相同,需要说明的是,所述的“位置对应”是指在各行中的排列次序相同,即,前三行中,每行从左到右(或从右到左)的第i个色阻块40的颜色不同,i大于零且小于等于每行中的像素区的个数。
作为本实用新型的再一方面,提供一种显示装置,包括本实用新型提供的上述显示面板。
以上为本实用新型提供的阵列基板、显示面板和显示装置的描述,可以看出,在本实用新型中,由于本实用新型的阵列基板的像素区的长度方向与阵列基板上第一取向层的取向方向成锐角,因此,在对阵列基板上的第一取向层进行摩擦取向时,摩擦辊与间隔区短暂接触后很快就会与像素区接触,从而使得摩擦辊基本上一直处于与像素区接触的状态,从而使摩擦辊表面不同区域受力更均匀,表面绒毛形态分布更均匀,减少长时间使用后出现的取向不良现象,提高显示产品的质量。相类似地,对盒基板上的第二取向层的取向方向也与像素区的长度方向成锐角,在对第二取向层进行取向时,摩擦辊表面的不同区域受力也更加均匀,防止长时间使用后产生取向不良的现象。另外,像素电极采用双畴结构,能够减少色偏现象;对盒基板上依次排列的n行色阻块中,位置对应的色阻块的颜色不同,从而提高色域。
可以理解的是,以上实施方式仅仅是为了说明本实用新型的原理而采用的示例性实施方式,然而本实用新型并不局限于此。对于本领域内的普通技术人员而言,在不脱离本实用新型的精神和实质的情况下,可以做出各种变型和改进,这些变型和改进也视为本实用新型的保护范围。
