具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本公开保护的范围。
相关技术中的阵列基板由于只在横向上具有gate层公共电极线,整个面板的公共电压的分布相对不均,公共电压不稳定,从而会造成显示不良。本公开实施例提供一种阵列基板,包括:透明的公共电极,多条第一公共电极线和多条第二公共电极线,所述多条第一公共电极线和多条第二公共电极线交叉设置,形成网格状,所述第一公共电极线通过第一过孔与所述公共电极连接,所述第二公共电极线通过第二过孔与所述公共电极连接。
本公开实施例中,为阵列基板的公共电极设置与其连接的网格状的公共电极线,能够有效降低公共电极的电阻,同时,由于公共电极线呈网格状分布,不是单纯的只有横向设置的gate层公共电极线,从而可以保证整个面板的公共电压的稳定均一,此外,由于网格状的公共电极线能够有效降低公共电极的电阻,从而可以相应减小每一条公共电极线的线宽,以提高开口率。
公共电极通常采用ITO等透明导电材料制成。
可选地,第一公共电极线和第二公共电极线可以采用金属导电材料制成,以有利于公共电极的电阻的减少。
然而,在本公开的其他一些实施例中,也不排除第一公共电极线和第二公共电极线采用透明导电材料制成,以提高开口率。
可选地,所述第一公共电极线和第二公共电极线形成的网格状结构覆盖公共电极所在区域。
本公开实施例中,所述第一公共电极线和第二公共电极线可以同层设置, 也可以异层设置。
当第一公共电极线和第二公共电极线同层设置时,所述第一公共电极线和第二公共电极线连接,为了避免与阵列基板的其他功能膜层上的图形造成干扰,该种情况下,第一公共电极线和第二公共电极线通常需要单独一层设置。
当所述第一公共电极线和第二公共电极线异层设置时,所述第一公共电极线和/或第二公共电极线可以与阵列基板上的其他功能膜层同层设置,以降低膜层厚度,可选地,还可以与其他导电层功能膜层同层设置,从而可以与该导电功能膜层通过一次构图工艺形成,节省mask数量,降低成本。
所述阵列基板还包括多条栅线,可选地,所述第一公共电极线可以与所述栅线同层设置,以节省mask数量,降低成本。进一步可选地,所述第一公共电极线可以与栅线平行设置。当然,在本公开的其他一些实施例中,也不排除所述第一公共电极线可以与栅线同层,且与栅线垂直设置的可能,此时,每一第一公共电极线需要在与栅线交叉的位置处断开。
所述第一公共电极线与所述栅线同层且平行设置时,可以是一行亚像素对应一条第一公共电极线,也可以是多行亚像素对应一条第一公共电极线。
所述阵列基板还包括多条数据线,可选地,所述第二公共电极线可以与所述数据线同层设置,以节省mask数量,降低成本。进一步可选地,所述第二公共电极线可以与数据线平行设置。当然,在本公开的其他一些实施例中,也不排除所述第二公共电极线可以与数据线同层,且与数据线垂直设置的可能,此时,每一第二公共电极线需要在与数据线交叉的位置处断开。
所述第二公共电极线与所述数据线线同层且平行设置时,可以是一列亚像素对应一条第二公共电极线,也可以是多列亚像素对应一条第二公共电极线。
请参考图,图1为本公开一实施例的阵列基板的俯视图,本公开实施例中的阵列基板为双栅型阵列基板,包括:多条栅线101和多条数据线102,相邻的两行亚像素之间设置有两条栅线101,相邻的两列亚像素之间,隔列设置一条数据线102,每一亚像素的公共电极103均分开设置。所述阵列基板还包括:多条第一公共电极线104和多条第二公共电极线105,所述第一 公共电极线104与所述栅线101同层且平行设置,所述第二公共电极线105与所述数据线同层且平行设置,所述第二公共电极线105设置于未设置所述数据线102的两列亚像素之间。所述第一公共电极线104和第二公共电极线105形成网格状。所述第一公共电极线104通过第一过孔106与所述公共电极103连接,所述第二公共电极线105通过第二过孔107与所述公共电极103连接。
本公开实施例中,利用双栅线型阵列基板隔列设置一条数据线的特殊结构,在未设置数据线的一列设置第二公共电极线,与第一公共电极线形成网格状的公共电极线,从而可以保证整个面板的公共电压的稳定均一,此外,由于网格状的公共电极线能够有效降低公共电极的电阻,从而可以相应减小每一条公共电极线的线宽,以提高开口率。
本公开实施例中,每一亚像素的公共电极103分开设置,处于同一行的公共电极103通过第一公共电极线104连通,处于同一列的公共电极103通过第二公共电极线105连通,从而使得整面公共电极103全部导通。
每一亚像素的公共电极分开设置的阵列基板,相关技术中,必须通过过孔以及上层金属(如源漏金属层或公共电极层)跨接布线使得相邻亚像素的公共电极导通,进而导通整面公共电极,这种设计不但增加了走线而且增加了走线与其它电极(如源漏电极、栅电极等)的交叠和侧向电容,电容的增加会使得负载增大,对亚像素充电同样造成影响。
本公开实施例中,无需设置跨接布线,在横向上通过第一公共电极线可将同行的公共电极连接起来,在纵向上通过第二公共电极线便可将同列的公共电极连接起来,结构简单,此外,还有效降低了公共电极与周边电极的电容,使得亚像素的充电更加容易。
请参考图2,图2为本公开另一实施例的阵列基板的剖面示意图,该实施例中的阵列基板与图1所示的实施例中的阵列基板的区别在于,公共电极103为条状公共电极,而图1所示的实施例中,公共电极103为块状公共电极。图2中,100为衬底基板,108为栅绝缘层,109为像素电极,110为绝缘层。
从图2中可以很明显的看出,通过第一过孔106和第二过孔107,公共 电极103可以与位于栅金属层的第一公共电极线104和位于源漏金属层的第二公共电极线105连接起来。其中第一过孔106为深过孔,第二过孔107为浅过孔。
本公开实施例中的阵列基板可以为HADS阵列基板,也可以为IPS阵列基板,或者其他类型的包括公共电极的阵列基板。
本公开实施例还提供一种显示面板,包括上述任一实施例中的阵列基板。
本公开实施例还提供一种显示装置,包括上述显示面板。
本公开实施例中的显示装置还可以包括驱动芯片,所述驱动芯片可以与第一公共电极线和/或第二公共电极线连接,用于通过第一公共电极线和/或第二公共电极线向公共电极传输公共电压信号。
本公开实施例还提供一种阵列基板的制作方法,包括形成透明的公共电极的步骤,以及形成多条第一公共电极线和多条第二公共电极线的步骤。所述多条第一公共电极线和多条第二公共电极线交叉设置,形成网格状,所述第一公共电极线通过第一过孔与所述公共电极连接,所述第二公共电极线通过第二过孔与所述公共电极连接。
可选地,所述第一公共电极线和第二公共电极线异层设置。
所述的阵列基板的制作方法,还包括形成多条栅线的步骤,可选地,所述第一公共电极线与所述栅线通过一次构图工艺形成,且平行于所述栅线。
所述的阵列基板的制作方法还包括形成多条数据线的步骤,其中,可选地,所述第二公共电极线与所述数据线通过一次构图工艺形成,且平行于所述数据线。
除非另作定义,本公开中使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性,而只是用来区分不同的组成部分。同样,“一个”或者“一”等类似词语也不表示数量限制,而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接,而是可以包括电性的连接,不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系,当被描述对象的绝对位置改变后,则该相对位置关系也相应地改变。
以上所述是本公开的可选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本公开所述原理的前提下,还可以作出若干改进和润饰,这些改进和润饰也应视为本公开的保护范围。
