本示例性实施例中,如图9、10所示,图9为本公开阵列基板母板另一种示例性实施例中阵列基板单元的结构示意图,图10为本公开阵列基板母板另一种示例性实施例中检测区的结构示意图。所述阵列基板单元还可以包括多个检测信号端32,每个检测信号端可以通过数据选择器161与多条信号线连接。相应的,阵列基板单元还可以包括多个开关电路33,所述阵列基板母板还可以包括多个位于所述检测区的公共探针垫2,所述公共探针垫、开关电路、检测信号端可以一一对应设置。在一一对应设置的所述公共探针垫、开关电路、检测信号端中,所述开关电路33可以连接所述第一控制信号端、所述第二控制信号端、所述公共探针垫2、所述检测信号端32,用于同时响应所述第一控制信号端、第二控制信号端的信号以导通所述公共探针垫和所述检测信号端。此外,如图9所示,阵列基板单元还可以包括多个子探针垫10,多个子探针垫10可以与多个检测信号端一一对应连接。其中,在检测区内,多个公共探针垫2可以相邻设置,相应的,外部检测设备与阵列基板母板的连接部可以包括多个相邻的探针,外部检测设备与阵列基板母板对接时,多个探针可以与多个公共探针垫一一对应接触。同理,多个子探针垫10也可以相邻设置,从而使得外部检测设备中的多个探针可以直接与多个子探针垫10一一对应接触。
本示例性实施例中,如图2、8、9所示,所述阵列基板单元可以包括位于切割线A-A两侧的检测电路区121和基板区122;所述阵列基板31可以集成于所述基板区122,所述开关电路33、子探针垫10、第三复位探针垫93、第四复位探针垫94、数据选择器161可以集成于所述检测电路区121;其中,所述切割线为在模组工艺中所述阵列基板母板的切割路径。在阵列基板母板完成检测等工艺后,可以沿切割线切割阵列基板母板,从而形成单个阵列基板。
应该理解的是,在其他示例性实施例中,所述阵列基板单元可以包括位于切割线同一侧的检测电路区和基板区;所述阵列基板集成于所述基板区,所述开关电路、子探针垫、第三复位探针垫、第四复位探针垫集成于所述检测电路区;其中,所述切割线为在模组工艺中所述阵列基板母板的切割路径。在阵列基板母板完成检测等工艺后,可以沿切割线切割阵列基板母板,从而形成单个阵列基板,该单个阵列基板包括有位于检测电路区的各个元器件。
本示例性实施例中,如图1所示,所述阵列基板母板还可以包括:多条第一栅线131、多条第二栅线132,多条第一栅线131沿行方向延伸,且连接同一行所述开关电路中的第一控制信号端;多条第二栅线132沿列方向延伸,且连接同一列所述开关电路中的第二控制信号端;所述第一栅极驱动电路4可以设置于所述阵列基板母板沿行方向的一侧,所述第一移位寄存器单元41的输出端连接所述第一栅线的一端;所述第二栅极驱动电路5可以设置于所述阵列基板母板沿列方向的一侧,所述第二移位寄存 器单元51的输出端连接所述第二栅线的一端。
本示例性实施例中,第一栅线131和第二栅线132自身存在压降,因此,远离第一栅极驱动电路的阵列基板单元相较于接近第一栅极驱动电路的阵列基板单元,其接收到第一栅线传输的驱动信号的驱动能力较弱。远离第二栅极驱动电路的阵列基板单元相较于接近第二栅极驱动电路的阵列基板单元,其接收到第二栅线传输的驱动信号的驱动能力较弱。从而本示例性实施例可能造成远离第一栅极驱动电路、第二栅极驱动电路一侧的阵列基板单元可能无法充分导通其中的开关电路。本示例性实施例中,如图7所示,为本公开阵列基板母板另一种示例性实施例的结构示意图。所述阵列基板母板还可以包括:第三栅极驱动电路14、第四栅极驱动电路15,第三栅极驱动电路14可以设置于所述阵列基板母板沿行方向的另一侧,包括多个级联的第三移位寄存器单元141,所述第三移位寄存器单元141的41输出端连接所述第一栅线的另一端;第四栅极驱动电路15可以设置于所述阵列基板母板沿列方向的另一侧,包括多个级联的第四移位寄存器单元151,所述第四移位寄存器单元151的输出端连接所述第二栅线的另一端。其中,所述第一移位寄存器单元、第二移位寄存器单元、第三移位寄存器单元、第四移位寄存器单元可以具有相同的结构。所述第一移位寄存器单元和第三移位寄存器单元可以同时向第一栅线提供驱动信号,第二移位寄存器单元和第四移位寄存器单元可以向第二栅线同时提供驱动信号,从而可以避免上述的“远离第一栅极驱动电路、第二栅极驱动电路一侧的阵列基板单元可以无法充分导通其中的开关电路”的技术问题。

本示例性实施例还提供一种阵列基板母板检测方法,用于检测上述的阵列基板母板,其包括:
利用所述第一栅极驱动电路和所述第二栅极驱动电路同时向目标阵列基板单元输入导通信号,以连接目标阵列基板单元的检查信号端和所述公共探针垫;
