具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白,下文中将结合附图对本公开的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
本发明中描绘的流程图仅仅是一个例子。在不脱离本发明精神的情况下,可以存在该流程图或其中描述的步骤的很多变型。例如,所述步骤可以以不同的顺序进行,或者可以添加、删除或者修改步骤。这些变型都被认为是所要求保护的方面的一部分。
除非上下文中另外明确地指出,否则在本文和所附权利要求中所使用的词语的单数形式包括复数,反之亦然。因而,当提及单数时,通常包括相应术语的复数。相似地,用语“包含”、“包括”、“含有”和“具有”及其语法变型旨在包括性的并且表示可以存在除所列要素之外的另外的要素。在本文中使用术语“示例”之处,特别是当其位于一组术语之后时,所述“示例”仅仅是示例性的和阐述性的,且不应当被认为是独占性的或广泛性的。术语“第一”、“第二”、“第三”等仅用于描述的目的,而不能理解为指示或暗示相对重要性及形成顺序。
随着液晶显示屏的发展和应用,从外挂触摸(GFF)产品到内嵌式(In Cell)产品需要增加静电放电(ESD)能力,从而减少产品损伤。在本公开的实施例中,利用阵列工艺(Array)在端子的上下膜层增加电路走线,形成电容结构,从而保护端子,避免静电损伤,提升产品的良率,增加收益,提升产品测试端子(ET Pad)处的抗ESD能力。
根据本公开的技术方案,可以在阵列基板中的任意两个导电层中形成电容结构,端子可以与电容结构的电极板在同一层导电层中形成,也可以在电容结构之间的导电层中形成。
ESD通常都是环境以及摩擦引起的,形成电容结构后,ESD优先通过该电容结构进行放电,而不是在ET pad等的端子上进行放电。静电再通过电容释放到GND上,这样产品就不会受到损坏。在同一层上设计的原理是一样的,如果在同一层设计时,因电容结构连接到GND,静电更容易在电容上放电而不在ET pad放电。
本公开实施例的阵列基板可包括多个端子、第一导电层和第二导电层,第一导电层和第二导电层之间可包括绝缘层,第一导电层和第二导电层中 分别形成有构成电容结构的多个第一电极板和多个第二电极板,第一电极板和第二电极板彼此相对以构成电容结构。该电容结构至少对应一个端子,即该端子邻近电容结构,该电容结构可以保护端子以避免静电放电的影响。端子可与第一导电层或与第二导电层同层设置,或者端子可与第一导电层与第二导电层之间的第三导电层同层设置。应理解,在本文中,术语“同层设置”表示由同一膜层形成。
图1示出了相关的阵列基板的结构的示意图。如图1所示,阵列基板一般包括:衬底基板1、缓冲层2、TFT晶体管5、平坦层6、阳极金属层7、像素限定层8、有机发光层9、阴极10。TFT晶体管5可包括源极电极51、漏极电极52、栅极53、有源层54、栅绝缘层55。阵列基板还可包括栅隔离层56。可在阳极金属层7中形成阳极和遮挡层。当然对于不同的阵列基板,不局限于上述的结构。
本公开的实施例中提到的导电层可以是以下的任意层:形成源极电极51的层、形成漏极电极52的层、形成栅极53的层、有源层54、阳极金属层7、有机发光层9、形成阴极10的层。
本公开的实施例还提供一种阵列基板的制造方法,图2示出了根据本公开的实施例的阵列基板的制造方法的流程图。如图2所示,制造方法可以包括以下步骤:
步骤S201、在第一导电层中形成多个第一电极板,例如,构图第一导电层形成第一电极板;
步骤S202、在第二导电层中形成分别与第一电极板彼此相对的多个第二电极板,其中,第一电极板和第二电极板可构成电容结构,例如,构图第二导电层形成第二电极板;
步骤S203、在第一导电层或第二导电层中形成多个端子,或者在第一导电层与第二导电层之间的第三导电层中形成多个端子,该电容结构至少对应一个端子,例如构图第一导电层、第二导电层和第三导电层形成端子。
上述制造方法的步骤不限定执行的先后顺序。
以下以实施例对本公开的阵列基板进行详细的说明。
图3示出了根据本公开的实施例的阵列基板的示意图,如图3所示,在本实施例中,端子100与构成电容结构的电极板101在同层设置,例如可在形成源极电极51的层中形成端子100和电极板101。如图3所示,端子100与电极板101交替相间布置,为了避免端子100与电极板101之间发生短路,在端子100与电极板101之间可填充有绝缘材料。
电极板201与电极板101相对,构成电容结构。例如,可在阳极金属层7中形成多个电极板201。
在本实施例中,端子100的引线在其它的导电层中形成,可以避免端子100的引线与电容结构发生短路。例如,端子100的引线与有源层54同层设置,穿过有源层54与形成源极电极51的层之间的各层形成过孔(未示出),端子100的引线通过过孔与端子100连接。
在本实施例中,以衬底基板1为最底层向上看,在端子100之上的各个层中,在与端子100对应的位置处形成有通孔,通孔用于暴露出端子100,以使外界的引脚能接触到端子100。
在本实施例中,通孔在衬底基板1上的正投影至少部分覆盖端子100,通孔的大小不作限定,只要能暴露出端子100即可。
制造图3所示的阵列基板的方法,可包括以下步骤:

图4示出了根据本公开的另一实施例的阵列基板的示意图。图4所示的阵列基板与图3所示的阵列基板的区别在于,端子100与电极板201同层设置。

端子100与电极板201交替相间布置,为了避免端子100与电极板201之间发生短路,在端子100与电极板201之间填充有绝缘材料。
穿过在阳极金属层7与该形成阴极10的层之间的各层形成过孔,端子100的引线通过过孔与端子100连接。
在本实施例中,以衬底基板1为最底层向上看,在端子100之上的各个层中,在与端子100对应的位置处形成有通孔,以暴露出端子100。
通孔在衬底基板1上的正投影至少部分覆盖端子100,通孔的大小不作限定,只要能暴露出端子100即可。
制造图4所示的阵列基板的方法,可包括以下步骤:
在衬底基板1上形成缓冲层2、在缓冲层2上形成TFT晶体管5,在形成TFT晶体管5的有源层54中形成多个电极板101;并在TFT晶体管5的上方或下方相对的位置形成遮挡层(未示出);在形成TFT晶体管5后的衬底基板1上依次形成阳极、像素限定层8、有机发光层9和阴极10。在形成阳极的阳极金属层7中形成端子100的引线,在形成阴极10的层中形成多个端子100和多个与电极板101相对的电极板201。
本公开的实施例中的端子还可形成在电容结构的两电极板之间的导电层中。
图5示出了根据本公开的又一实施例的阵列基板的示意图。如图5所示,在本实施例中,可在有源层54中形成有多个电极板101,在形成栅极53的层中形成多个端子100和端子100的引线,在阳极金属层7中形成多个与电极板101相对的电极板201,电极板101与相对的电极板201构成电容结构。
在本实施例中,以衬底基板1为最底层向上看,在端子100之上的各 个层中,在与端子100对应的位置处形成有通孔,以暴露出端子100。
通孔在衬底基板1上的正投影至少部分覆盖端子100,通孔的大小不作限定,只要能暴露出端子100即可。
