如图1所示,采用GOA(gate on array,闸极驱动电路基板)技术的具有闸极阵列驱动的显示面板,包括彩色滤光片基板10、阵列基板20、驱动器30和闸机驱动电路40,通过采用闸机驱动电路40制作在阵列基板20上,代替由外接硅芯片制作的驱动芯片以驱动薄膜晶体管的通断。由于GOA(gate on array,闸极驱动电路基板)技术可以直接在显示面板的显示区域周围设置闸机驱动电路40,简化制作程序,提高显示面板的整合度,使得显示面板可以实现超薄设计。
采用闸机驱动电路进行闸极驱动时,电容负载电路如图2所示,驱动器发送的时钟电压讯号100经讯号线发送至主动开关,讯号线所产生的讯号电阻200,讯号电容300和并联在主动开关的控制端b和主动开关500的第一端a之间的并联电容400。讯号电阻200、讯号电容300和并联电容400均落在第一端a和控制端b上,电路负载过重,影响时钟讯号传输效果。
为了解决上述技术问题,本发明实施例提供了一种阵列基板,如图3所示,阵列基板,包括:第一基板1;形成于第一基板1上的第一导电层2;形成于第一导电层2上的第一钝化层3,且第一钝化层3覆盖部分第一基板1;形成于第一钝化层3上的第二导电层4;形成于第二导电层4上的第二钝化层5,且第二钝化层5覆盖部分第一钝化层3;形成与第二钝化层5上的第一电极层6,第一电极层6覆盖部分第一导电层2、第一钝化层3、第二导电层4和第二钝化层5;形成于第一电极层6上的液晶层7;形成于液晶层7上的第二电极层8;形成于第二电极层8上的第二基板9;第一导电层2包括多条第一走线21,第二导电层4包括多条与各第一走线21对应的第二走线41,其中,各第一走线21通过对应的第一电极层6的走线连接对应的第二走线41;各第一走线21上设置有目标区域91,各第二走线41在对应连接的第一走线21上的投影位于对应的目标区域91里面,目标区 域91是用于降低第一走线21与第二电极层8之间电容的区域。
其中,第一走线21的目标区域91是指用于降低第一走线21与第二电极层8之间的电容的区域。目标区域91内的第一走线21可以是镂空状态,目标区域91内的第一走线21还可以设置有凹槽、凹槽中填充有非导电材料,以减小平板间电容。即目标区域91内的这部分第一走线21(可以是实体金属,也可以是第一走线21上的镂空部分等)与所对的第二电极层8之间形成的电容C1小于目标区域外的这部分第一走线21与第二电极层8之间形成的电容。具体实现方式不仅限于此处所举的两个例子。本发明实施例采用在第一走线21与其对应的第二走线41的重叠区域设置目标区域91,有效降低闸机驱动电路走线的电容值,减小闸机驱动电路走线负载及降低平板功率。
在其中一个实施例中,如图3至图5所示,目标区域91包括第一走线21与各第二走线41形成的跨线区域911。跨线区域911,是指第一走线和第二走线交叉不连接的部分。本发明实施例采用在第一走线21与各第二走线41的跨线区域设置目标区域91,有效降低闸机驱动电路走线的电容值,减小闸机驱动电路走线负载及降低平板功率。
在其中一个实施例中,如图4和图5所示,目标区域91还包括第一走线21与第二走线41的交叉连接区域912。交叉连接区域912是指和第二走线41在对应连接的第一走线21上的投影有交集的区域。在第一走线21与第二走线41交叉连接处区域912挖孔或填充树脂等非导电材料,降低电容,从而降低闸机驱动电路的电路负载。
在其中一个实施例中,如图3至图5所示,第一钝化层3在目标区域91覆盖部分第一基板1。第一钝化层3在目标区域91覆盖部分第一基板1,即第一走线21上挖设有孔,在该孔处无导电材料,第一钝化层3填充该部分区域,并与第一基板1接触,降低平板电容,从而降低闸机驱动电路走线的电容值。
在其中一个实施例中,如图3至图5所示,目标区域91填充有非导电材料。在目标区域91填充树脂等非导电材料,减小平板间电容,以降低闸机驱动电路走线的负载。
在其中一个实施例中,如图3至图5所示,第一导电层2上形成有第一类导电桥接洞,第一电极层6覆盖于第一导电层2上。
在其中一个实施例中,如图3至图5所示,第二导电层4上也形成有第二类导电桥接洞,第一电极层6覆盖于第二导电层4上。
在其中一个实施例中,如图3至图5所示,第一类导电桥接洞至少为两个。
在其中一个实施例中,如图3至图5所示,第二类导电桥接洞至少为两个。
在其中一个实施例中,液晶层7具有一介质系数,介质系数包括平行向量的介电系数与垂直向量的介电系数。在各第一走线21上形成第一类导电桥接洞,并同时将第一电极层6覆盖于第一导电层2上,透过导电桥接洞传送电压讯号于第一电极层6及第二电极层8,因而使液晶层7的所述介质系数趋近为平行向量的介电系数(举例:由电压信号大小控制介电系数方向的倾斜度),而有效进一步降低闸机驱动电路走线的电容值。同理,在各第二走线41上形成第二类导电桥接洞,并同时将第二电极层8覆盖于第二导电层4上,透过导电桥接洞传送电压讯号于第二电极层8及第二电极层8,因而使液晶层7的所述介质系数趋近为平行向量的介电系数(举例:由电压信号大小控制介电系数方向的倾斜度),而有效进一步降低闸机驱动电路走线的电容值。
一种显示面板,如图1、图5所示,包括彩色滤光片基板10、驱动器30和上述阵列基板20。本发明实施例提供的显示面板,驱动器30产生的时钟讯号给到阵列基板20上的第一走线21和第二走线41,以驱动薄膜晶体管,在各第二走线40对应的第一走线21上设置目标区域91,使得该第二走线41在第一走线21上的投影落在该目标区域91内,即使得第二走线41与其连接的第一走线21的交叠处的电容最小化,从而降低闸机驱动电路40走线的电容值,降低平板功率。
在其中一个实施例中,目标区域91可以包括第一走线21与各第二走线41形成的跨线区域911,和/或,第一走线21与第二走线41的交叉连接区域912。
一种阵列基板制作方法,包括:
提供第一基板;在第一基板上形成第一导电层;在第一导电层上形成第一钝化层,且使得第一钝化层覆盖部分第一基板;在第一钝化层上形成第二导电层;在第二导电层上形成第二钝化层,且使得第二钝化层覆盖部分第一钝化层;在第二钝化层上形成第一电极层,且使得第一电极层覆盖部分第一导电层、第一钝化层、第二导电层和第二钝化层;在第一电极层上形成液晶层;在液晶层上形成第二电极层;在第二电极层上形成第二基板;在第一导电层上形成多条第一走线,在第二导电层上形成多条与各第一走线对应的第二走线,各第一走线通过对应的第一电极层的走线连接对应的第二走线;在第一走线上形成有目标 区域,第二走线在第一走线上的投影位于目标区域里面。需要说明的是,本实施例中的名词释义与上述实施例中相同,工作原理也相同,在此不做赘述。其中,目标区域91可以包括第一走线21与各第二走线41形成的跨线区域911,和/或,第一走线21与第二走线41的交叉连接区域912。
在本申请中的某些实施例中,显示面板可以包括液晶面板,液晶面板可以包括开关阵列基板,彩色滤光层基板与形成于两基板之间的液晶层,显示面板还可以是OLED(Organic Light-Emitting Diode,有机电激光显示)面板或QLED(Quantum Dot Light Emitting Diodes,量子点发光二极管)面板。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
