具体实施方式
本申请实施例提供了一种阵列基板,如图1所示,该阵列基板包括多条沿第一方向Y延伸且沿第二方向X排列的虚设引线(dummy)3和数据线(未示出),所述第一方向Y与所述第二方向X交叉;所述虚设引线与数据线同层设置,每一所述虚设引线3包括多条沿第一方向Y延伸且相互断开的导线4。
本申请实施例提供的阵列基板,由于虚设引线包括多条沿第一方向延伸且相互断开的导线,与现有技术设置一整根虚设引线相比,当位于同层的虚设引线与数据线发生短路时,与数据线短路的导线的长度减小,数据线的电压降低程度减小,从而可以避免出现显示暗纹,提高显示效果,提升用户体验。
可选地,本申请实施例提供的如图1所示的阵列基板中,每一所述虚设引线3中不同所述导线4在沿第一方向Y延伸的同一直线上。可以保证虚设引线在阵列基板所在区域均匀排列,进一步保证产品的显示均一性。
可选地,如图1所示,不同所述导线4的长度相等。从而可以保证数据线电压降低的程度相同。
可选地,本申请实施例提供的如图1所示的阵列基板还包括阵列分布的触控电极5,所述阵列分布的触控电极包括多个触控电极列6,所述触控电极列6的列方向为所述第一方向Y,每一所述虚设引线3中的所述导线4的条数与一所述触控电极列6中触控电极5的个数相等。这样,便于阵列基板的结构设计,同时使得形成多段导线的工艺易于实现。
可选地,在所述阵列基板所在的平面内,每一触控电极列的正投影与至少一条所述虚设引线的正投影存在重叠区域。
可选地,本申请实施例提供的如图1所示的阵列基板,在所述阵列基板所在的平面内,每一所述虚设引线3中,相邻两条所述导线4之间的间隔区域的正投影,落入每一触控电极列6中相邻两个所述触控电极5之间的间隔区域的正投影。
本申请实施例提供的如图1所示的阵列基板,每一条虚设引线3中导线4的条数与触控电极列6中触控电极5的个数相等,这样,便于阵列基板的结构设计,同时使得形成多段导线的工艺易于实现,在此基础上,每一条虚设引线3中不同导线4的长度相等,从而可以保证每一导线的长度最短,最大程度减小数据线电压降低。
可选地,所述阵列基板还包括阵列排布的像素单元以及多条沿所述第一方向延伸且沿所述第二方向排列的触控引线,每一所述触控电极至少与一条所述触控引线连接,所述阵列排布的像素单元包括多个像素单元列,所述像素单元列的方向为所述第一方向,所述虚设引线的数量和所述触控引线的数量之和等于所述像素单元列的数量。
如图1所示,阵列基板包括与触控电极5连接的触控引线2,还包括与触控引线2和虚设引线3连接的驱动电路7,所述驱动电路7为所述虚设引线3提供公共电压信号以及为所述触控引线2提供公共电压信号和触控信号,触控引线2与触控电极5电连接位置为区域24。图1中以每一触控引线与触控电极通过两个区域24电连接为例进行说明,在具体实施时,触控引线与触控电极也可以只有一个连接区或更多的连接区,本申请不进行限制。图2为部分像素单元与引线关系示意图,图3中,每一像素单元8包括三个子像素单元9,每一子像素单元由相互交叉的栅线Gate和数据线Data划分,每一子像素单元9包括与栅线和数据线连接的薄膜晶体管10(TFT)以及与TFT连接的像素电极11,每一像素单元8组成的像素单元列对应一条虚设引线3或触控引线2,这样可以保证引线的数量与像素单元列的数量相等,从而可以保证产品的显示均一性。此外,当每一所述虚设引线中不同所述导线沿第一方向重合,可以保证引线在阵列基板所在区域均匀排列,进一步保证产品的显示均一性。
需要说明的是,每一触控电极列对应N个像素单元列,每一触控电极列包括M个触控电极,当M<N,且每一触控电极连接1条触控引线时,为了保证显示均一性,每一触控电极列覆盖区域需要设置N-M条虚设引线。图1只是以每一触控电极列的正投影覆盖1条虚设引线的正投影为例进行说明,在实际设计阵列基板结构时,为了保证显示均一性,需要根据M、N以及每一触控电极连接的引线的条数来确定每一触控电极列需要对应多少条虚设引线。此外,图1中的触控电极为矩形,当然触控电极也可以是其他形状,阵列基板触控电极的形状以及引线设置可以根据实际需要进行选择。
可选地,每一所述触控引线包括位于不同层、通过过孔连接且重叠设置的第一子触控引线和第二子触控引线,所述第二子触控引线与所述数据线同层设置。即虚设引线与第二子触控引线同层设置。位于不同层且重叠设置的第一子触控电极和第二子触控电极通过过孔连接,从而能够降低触控引线的电阻,将第二子触控引线与数据线同层设置可以简化阵列基板制作工艺。接下来分别以图2中沿AA’、BB’的截面图为例,对本申请实施例提供的阵列基板的结构进行举例说明,如图3所示,图2中沿AA’的截面的阵列基板包括:衬底基板12、栅极13、栅绝缘层14、有源层15、源极16、漏极17、与漏极17连接的像素电极11、与源极16和漏极17同层设置的数据线18和第二子触控引线19、第一绝缘层20、通过设置在第一绝缘层20上的过孔21与第二子触控引线19连接的第一子触控引线22、第二绝缘层23、以及通过设置在第二绝缘层23上的过孔21与第一子触控引线22连接的触控电极5。其中,第二子触控引线19可以称为SDT(Source Data Metal)线,第一子触控引线22可以称为TPM(TouchPanel Metal)线,本申请实施例中与SDT线同层设置的虚设引线可以成为dummy SDT线,在垂直阵列基板方向上,与dummy SDT线重叠的区域,还可包括与第一子触控引线22同层设置的dummy TPM线,dummy TPM线也可包括多条沿第一方向延伸且相互断开的导线,如图4所示,图2中沿BB’的截面的阵列基板包括:衬底基板12、栅极13、栅绝缘层14、有源层15、源极16、漏极17、与漏极17连接的像素电极11、与源极16和漏极17同层设置的数据线18和虚设引线3、第一绝缘层20、dummy TPM线24、第二绝缘层23、以及触控电极5。
本申请实施例提供了一种显示面板,包括本申请实施例提供的上述所述的阵列基板。本申请实施例提供的显示面板例如可以是触控与显示驱动器集成(Touch and DisplayDriver Integration,TDDI)型显示面板,可以是液晶显示面板,也可以是有机发光二极管显示面板。
本申请实施例提供了一种显示装置,包括本申请实施例提供的显示面板。
本申请实施例提供的显示装置例如可以是手机、平板电脑等装置。
基于同一发明构思,本申请实施例还提供一种阵列基板的制备方法,该方法包括:在衬底上形成虚设引线的图案和数据线的图案的步骤;
其中,每一所述虚设引线的图案包括:多条沿第一方向延伸且相互断开的导线的图案。
可选地,形成虚设引线的图案具体包括:利用包括多个沿同一方向延伸且相互断开的开口的掩膜板形成所述虚设引线的图案。
接下来对本申请实施例提供的阵列基板制备方法中采用的掩膜板进行举例说明,如图5所示,掩膜板25包括多个沿第一方向Y延伸且相互断开的开口26,且部分开口沿第一方向重合,例如区域27中的多个开口沿第一方向Y重合,在利用该掩膜板蒸镀金属材料,便可在衬底上区域27对应的部分形成多条沿第一方向重合且断开的导线,构成一条虚设引线。具体的,例如可以在衬底上形成触控引线的图案以及数据线的图案;之后再利用如图5所示的掩膜板形成虚设引线的图案。
综上所述,本申请实施例提供的阵列基板及其制备方法、显示面板、显示装置,由于虚设引线包括多条沿第一方向延伸且相互断开的导线,与现有技术设置一整根虚设引线相比,当位于同层的虚设引线与数据线发生短路时,与数据线短路的导线的长度减小,数据线的电压降低程度减小,从而可以避免出现显示暗纹,提高显示效果,提升用户体验。本申请实施例提供的阵列基板,每一条虚设引线中导线的条数与触控电极列中触控电极的个数相等,这样,便于阵列基板的结构设计,同时使得形成多段导线的工艺易于实现,在此基础上,每一条虚设引线中不同导线的长度相等,从而可以保证每一导线的长度最短,最大程度减小数据线电压降低。本申请实施例提供的阵列基板,虚设引线的数量和触控引线的数量之和等于像素单元列的数量,从而可以保证产品的显示均一性。此外,当每一所述虚设引线中不同所述导线沿第一方向重合,可以保证引线在阵列基板所在区域均匀排列,进一步保证产品的显示均一性。
显然,本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样,倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内,则本申请也意图包含这些改动和变型在内。
