具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，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。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“耦接”和“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“连接”和“串接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。又如，描述一些实施例时可能使用了术语“耦接”以表明两个或两个以上部件有直接物理接触或电接触。然而，术语“耦接”或“通信耦合(communicatively coupled)”也可能指两个或两个以上部件彼此间并无直接接触，但仍彼此协作或相互作用。这里所公开的实施例并不必然限制于本文内容。
“A、B和C中的至少一个”与“A、B或C中的至少一个”具有相同含 义，均包括以下A、B和C的组合：仅A，仅B，仅C，A和B的组合，A和C的组合，B和C的组合，及A、B和C的组合。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
“上/上方”、“下/下方”、“行/行方向”以及“列/列方向”等指示的方位或位置关系的术语为基于附图所示的方位或位置关系，仅是为了便于说明本公开的技术方案的简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。
例如，在某些情况下，涉及“行方向”的实施例可以在“列方向”的情况下实施等等，相反亦如此。将本公开所述方案进行90°旋转或镜像后亦属本公开要求保护的权利范畴。
如图1、图2a、图2b以及图3所示，本公开的一些实施例提供一种阵列基板02。在该阵列基板02中，采用内嵌式(in cell)的触控结构，将用于实现触控功能的触控电极集成于阵列基板02的内部，实现对触摸位置的检测。
请参阅图3，该阵列基板02包括：衬底基板1、设置于衬底基板1一侧的公共电极层2、第一导电层3以及第二导电层4。
第一导电层3设置于公共电极层2靠近或远离衬底基板1的一侧。例如，如图3所示，第一导电层3相对于公共电极层2靠近衬底基板1。再如，在另一些实施例中，第一导电层3相对于公共电极层2远离衬底基板1。
第二导电层4设置于公共电极层2靠近或远离衬底基板1的一侧。例如，如图3所示，第二导电层4相对于公共电极层2靠近衬底基板1。再如，在另一些实施例中，第二导电层4相对于公共电极层2远离衬底基板1。
请参阅图1、图2a和图2b，其中，公共电极层2包括阵列式布置的多个公共电极21。
此处，阵列式布置可以是排布成多行和多列，例如，图1中以4行6列进行示意。设定多个公共电极21排列的行方向为第一方向D1，列方向为第二方向D2。可以理解的是，多个公共电极排列的行方向和列方向相互交叉，即第一方向D1与第二方向D2相互交叉，例如第一方向D1与第二方向D2相互垂直。
在本公开实施例中，在阵列基板02驱动的显示阶段，公共电极层2与阵列基板02的像素电极层7配合形成电场，以驱动显示面板的各子像素PX进行显示。请参阅图1，在阵列基板02驱动的触控阶段，公共电极层2的多个公共电极21中的一部分公共电极21被复用为第一触控电极211，多个公共电 极21中的另一部分公共电极21被复用为第二触控电极212，以实现触摸位置的检测。即，公共电极层2既具有驱动显示的功能，又具有触摸位置检测的功能，实现了对公共电极层2的复用。由此，相对于相关技术中，既设置用于实现显示功能的公共电极层，又设置用于实现触摸位置检测功能的触控电极层的技术方案，本公开实施例提供的阵列基板02可以减小阵列基板02的整体厚度，简化阵列基板02的内部结构。
请参阅图1、图2a、图2b和图3，第一导电层3包括多条电极连接线31。沿第一方向D1排列的每行第一触控电极211被多条电极连接线31中的至少一条电极连接线31串接，这相当于形成了沿第一方向D1延伸的多行第一触控电极条211C。
示例性地，如图4所示，每行第一触控电极211被一条电极连接线31串接。这样，在实现每行第一触控电极211被串接成一行第一触控电极条211C的前提下，布线较简单。
示例性地，如图1所示，每行第一触控电极211被多条电极连接线31串接。这样，每行第一触控电极条211C中的各个第一触控电极211之间，通过多条电极连接线31传输第一触控信号S1，可以提高第一触控电极条211C上信号的传输速度和均一性，从而在阵列基板02实现触摸位置检测功能时，提高触摸位置定位的准确性。
在本公开实施例中，如图1所示，串接一行第一触控电极211的多条电极连接线31可以均沿第一方向D1延伸，且沿第二方向D2并列设置。
在图1中，串接一行第一触控电极211的多条电极连接线31的数量以4条为例进行示意，在本公开的其他一些实施例中，串接一行第一触控电极211的多条电极连接线31的数量可以是3条、5条、6条、7条、8条等。
请继续参阅图1、图2a、图2b和图3，第二导电层4包括多条第一触控信号线41和多条第二触控信号线42。其中，每条第一触控信号线41被配置为传输第一触控信号S1；每条第二触控信号线42被配置为传输第二触控信号S2。
需要说明的是，在本公开的实施例中，每条第一触控信号线41和每条第二触控信号线42均与触控芯片01电连接。在本公的实施例的附图中，左侧标有第一触控信号S1的导电线是第一触控信号线41；左侧标有第二触控信号S2的导电线是第二触控信号线42。以及，出现在下文中的各条虚拟触控信号线46，与触控芯片01不连接。并且在各个附图中，沿第二方向D2延伸的导电线中，既没有标第一触控信号S1也没有标第二触控信号S2的导电线，是 虚拟触控信号线46。对此，下文中不再赘述。
请继续参阅图1、图2a、图2b和图3，沿第一方向D1排列的每行第一触控电极211(即每行第一触控电极条211C)与多条第一触控信号线41中的至少一条第一触控信号线41耦接。这样，每行第一触控电极211，可以通过其所耦接的各条第一触控信号线41，从触控芯片01处获得第一触控信号S1，或者向触控芯片01传输第一触控信号S1。
示例性地，如图1所示，第1行第一触控电极211(即第1行第一触控电极条211C)中，位于第2列的第一触控电极211与一条第一触控信号线41耦接。又因第1行的各第一触控电极211被4条电极连接线31串接，这样一来，第1行的各第一触控电极211与该条第一触控信号线41耦接。
此处，在图1中，与每行第一触控电极211耦接的第一触控信号线41的数量以1条为例进行示意。在本公开的其他一些实施例中，与每行第一触控电极211耦接的第一触控信号线41的数量可以是2条、3条、4条、5条等。
此处需要说明的是，在本公开提供的实施例中，第n行是指在第二方向D2上，从上往下数第n行；第m列是指在第一方向D1上，从左往右数第m列。另外，在下文中提到的，第x条电极连接线31是指在第二方向D2上，从上往下数第x条电极连接线31；第y条第一触控信号线41、第y条第二触控信号线42、第y条虚拟触控信号线46分别是指在第一方向D1上，从左往右数第y条第一触控信号线41、第y条第二触控信号线42、第y条虚拟触控信号线46。
请继续参阅图1、图2a、图2b和图3，每个第二触控电极212或沿第二方向D2排列的每列第二触控电极212与多条第二触控信号线42中的至少一条第二触控信号线42耦接。这样，每个第二触控电极212或沿第二方向D2排列的每列第二触控电极212，可以通过其所耦接的各条第二触控信号线42，从触控芯片01处获得第二触控信号S2，或者向触控芯片01传输第二触控信号S2。
示例性地，如图1所示，每个第二触控电极212与一条第二触控信号线42耦接。
示例性地，如图10所示，沿第二方向D2排列的每列第二触控电极212与一条第二触控信号线42耦接，这相当于形成了沿第二方向D2延伸的多列第二触控电极条212C。
此处，在图1中，每个第二触控电极212所耦接的第二触控信号线42的数量以1条为例进行示意。在图10中，沿第二方向D2排列的每列第二触控 电极212所耦接的第二触控信号线42的数量以1条为例进行示意。在本公开的其他一些实施例中，每个第二触控电极212或沿第二方向D2排列的每列第二触控电极212所耦接的第二触控信号线42的数量可以是多条，例如2条、3条、4条、5条等。
并且，在图1中，为了清楚地示出各条第一触控信号线41、各条第二触控信号线42和各条电极连接线31，以及它们与各个公共电极21的连接关系，将各条第一触控信号线42、各条第二触控信号线42和各条电极连接线31画在了各个公共电极21的上方，但是这并不代表它们的实际膜层位置。
另外，图1～图3仅示意出了阵列基板02的局部，该阵列基板02中包括的公共电极21的实际数量远多于图1～图3示意出的数量。图1～图3所示出的公共电极21的数量仅为示例。
基于此，本公开上述实施例提供的阵列基板02包括了两种触控电极，一种为多行第一触控电极条211C，另一种为多个第二触控电极212或多列第二触控电极条212C。这两种触控电极形成了互容式触控结构，即在触控阶段，多行第一触控电极条211C被配置为驱动电极和感应电极中的一种，多个第二触控电极212或多列第二触控电极条212C被配置为驱动电极和感应电极中的另一种。驱动电极和感应电极之间形成电容，即驱动电极和感应电极分别构成了电容的两极。
在人的手指触摸触控区域时，影响触摸点附近驱动电极和感应电极之间的耦合，从而改变了触摸点附近驱动电极和感应电极之间的电容量。在进行触摸检测时，检测电容大小，驱动电极发出驱动信号，感应电极接收感应信号，这样可以得到所有驱动电极和感应电极之间的电容值大小，即整个触控屏的电容变化量数据，从而可以计算出每一个触摸点的坐标。这样，即使触控区域有多个触摸点，也能计算出每个触摸的真实坐标，即可以实现多点触控。
而且，由于本公开实施例提供的阵列基板02的显示功能和触控分时进行，两种功能相互之间的干扰较少，因此触控灵敏度较高。
在一些实施例中，各第一触控电极条211C被配置为驱动电极，用于在进行触摸位置检测时被加载驱动信号TX。各第二触控电极212或各第二触控电极条212C被配置为感应电极，用于在驱动信号TX的作用下产生感应信号RX。
示例性的，各第一触控电极条211C被配置为驱动电极；相应地，各条第一触控信号线41被配置为驱动信号线。在触控阶段，各条第一触控信号线41 向其所耦接的各第一触控电极条211C传输进行触摸位置检测所需的驱动信号TX。各第二触控电极212或各第二触控电极条212C被配置为感应电极；相应地，各第二触控信号线42被配置为感应信号线。在触控阶段，各第二触控信号线42从其所耦接的各第二触控电极212或各第二触控电极条212C处获取进行触摸位置检测所得到的感应信号RX，并传输感应信号RX。
在一些实施例中，各第二触控电极212或各第二触控电极条212C被配置为驱动电极，用于在进行触摸位置检测时被加载驱动信号TX。各第一触控电极条211C被配置为感应电极，用于在驱动信号TX的作用下产生感应信号RX。
示例性的，各第二触控电极212或各第二触控电极条212C被配置为驱动电极；相应地，各条第二触控信号线42被配置为驱动信号线。在触控阶段，各条第二触控信号线42向其所耦接的各第二触控电极212或各第二触控电极条212C传输进行触摸位置检测所需的驱动信号TX。各第一触控电极条211C被配置为感应电极；相应地，各条第一触控信号线41被配置为感应信号线。在触控阶段，各第一触控信号线41从其所耦接的第一触控电极条211C处获取进行触摸位置检测所得到的感应信号RX，并传输感应信号RX。
需要说明的是，如图2a、图2b和图3所示，阵列基板02的每个子像素均包括设置于衬底基板1上的薄膜晶体管TFT和像素电极71。公共电极层2可设置在薄膜晶体管TFT和各个像素电极71所在的像素电极层7之间，或者设置在像素电极层7远离衬底基板1的一侧。
需要说明的是，在本公开提供的各实施例中，位于公共电极层2的各公共电极21为一块块独立的块状电极，一个公共电极21可以对应一个像素电极71，如图2a和图2b所示，也可以对应多个相邻的像素电极71(或者说“覆盖相邻的多个像素电极71”)。
薄膜晶体管TFT包括栅极32、有源层10、源极43和漏极44；源极43和漏极44分别与有源层10接触，漏极44与像素电极71电连接。其中，栅极32处于栅电极层3＇中，源极43和漏极44位于源漏电极层4＇中。
在一些实施例中，如图3所示，第一导电层3为栅电极层3＇，第一导电层3位于衬底基板1与公共电极层2之间。也就是说，第一导电层3中的多条电极连接线31位于栅电极层3＇中。可以理解的是，栅电极层3＇还包括多个栅极32和多条栅线(图3中未示意出栅线)。由此，各条电极连接线31、各个栅极32和各条栅线33可以通过同一构图工艺形成，从而无需额外设置形成各条电极连接线31的步骤，达到了简化阵列基板02的制作工艺的效果。
例如，如图2a和图2b所示，各条电极连接线31与各条栅线33之间相互平行设置。可以理解的是，各条电极连接线31与各个栅极32和各条栅线33之间相互电性绝缘。
请继续参阅图3，在一些实施例中，第二导电层4为源漏电极层4＇，第二导电层4位于栅电极层3＇与公共电极层2之间。也就是说，第二导电层4中的多条第一触控信号线41和多条第二触控信号42线位于源漏电极层4＇中。可以理解的是，源漏电极层4＇还包括多个源极43、多个漏极44、多条数据线(图3中未示意出数据线)。由此，各条第一触控信号线41、各条第二触控信号42、各源极43、各漏极44以及各条数据线可以通过同一构图工艺形成，从而无需额外设置形成各条第一触控信号线41和各条第二触控信号42的步骤，达到了简化阵列基板02的制作工艺的效果。
例如，如图2a和图2b所示，各条第一触控信号线41、各条第二触控信号42和各条数据线45之间相互平行设置。可以理解的是，各条第一触控信号线41、各条第二触控信号42、各源极43、各漏极44以及各条数据线45之间相互电性绝缘。
基于此，由于栅电极层3＇和源漏电极层4＇为阵列基板02中用于形成薄膜晶体管TFT的膜层，只需要对它们的图案和电连接关系做出上述的设计，即可将多条电极连接线31设置于栅电极层3＇，将多条第一触控信号线41和多条第二触控信号线42设置于源漏电极层4＇，从而无需增加新的导电层，即可实现互容式触控。也就是说，将多条电极连接线31的制备兼容于栅电极层3＇的制备中，将多条第一触控信号线41和多条第二触控信号线42的制备兼容于源漏电极层4＇的制备中，从而能够在不增加构图工艺的前提下，将用于触控的结构集成于阵列基板02内部，并且实现互容式触控。
在阵列基板02中，不同导电层之间设有起隔离作用的绝缘层，例如，如图3所示，设于有源层10和栅电极层3＇之间的栅极绝缘层11、设于栅电极层3＇和源漏电极层4＇之间的层间介质层5＇、设于源漏电极层4＇和公共电极层2之间的第二绝缘层6、设于像素电极层7与公共电极层2之间的第三绝缘层8。
本公开实施例中的薄膜晶体管TFT可以是底栅型薄膜晶体管，也可以是顶栅型薄膜晶体管。
在一些实施例中，如图3所示，在薄膜晶体管TFT是顶栅型薄膜晶体管的情况下，在垂直于衬底基板1且由靠近衬底基板1指向远离衬底基板1的方向上，衬底基板1上依次设置有有源层10、栅极绝缘层11、栅电极层3＇、 层间介质层5＇、源漏电极层4＇和第二绝缘层6。在第二绝缘层6远离衬底基板1的一侧还设置有公共电极层2、像素电极层7和位于二者之间的第三绝缘层8，其中，公共电极层2可相对于像素电极层7更靠近或者更远离衬底基板1，本公开实施例的附图中以公共电极层2相对于像素电极层7更靠近衬底基板1为例进行示意。
可见，基于上述结构，源漏电极层4＇和栅电极层3＇之间设有一层绝缘层，即层间介质层5＇。也就是说，在第一导电层3为栅电极层3＇，第二导电层4为源漏电极层4＇的情况下，对于具有顶栅型薄膜晶体管的阵列基板01而言，第一导电层3与第二导电层4之间设有层间介质层5＇。
在一些实施例中，在薄膜晶体管TFT是底栅型薄膜晶体管的情况下，在垂直于衬底基板且由靠近衬底基板指向远离衬底基板1的方向上，衬底基板上依次设置有栅电极层、栅极绝缘层、有源层、源漏电极层和第四绝缘层。在第四绝缘层远离衬底基板的一侧还设置有公共电极层、像素电极层和位于二者之间的第五绝缘层，其中，公共电极层可相对于像素电极层更靠近或者更远离衬底基板。
可见，基于上述结构，源漏电极层4＇和栅电极层3＇之间设有一层绝缘层，即栅极绝缘层11。也就是说，在第一导电层3为栅电极层3＇，第二导电层4为源漏电极层4＇的情况下，对于具有底栅型薄膜晶体管的阵列基板02而言，第一导电层3与第二导电层4之间设有栅极绝缘层11。
下面以本公开实施例提供的阵列基板02的薄膜晶体管TFT是顶栅型薄膜晶体管为例，对如何利用电极连接线31将沿第一方向D1排列的每行第一触控电极211串接进行说明。可以理解的是，本公开的实施例包括但不限于下述实施例中提供的实现方式。
在一些实施例中，如图1和图3所示，阵列基板01还包括：设置于第一导电层3与第二导电层4之间的第一绝缘层5，及设置于第二导电层4与公共电极层2之间的第二绝缘层6。由上面的描述可知，在第一导电层3为栅电极层3＇，第二导电层4为源漏电极层4＇且阵列基板02的薄膜晶体管TFT是顶栅型薄膜晶体管的情况下，该第一绝缘层5即为层间介质层5＇。
继续参阅图1和图3，第一绝缘层5中设有贯通第一绝缘层5的多个第一过孔P1，以及第二绝缘层6中设有贯通第二绝缘层6的多个第二过孔P2。结合图1和图3所示，每行第一触控电极211依次通过多个第二过孔P2中的一些第二过孔P2和多个第一过孔P1中的一些第一过孔P1与至少一条电极连接线31耦接(图1中仅以四条电极连接线31为例进行示意)。
示例性的，如图1所示，每行第一触控电极211中的各第一触控电极211依次通过4个第二过孔P2和4个第一过孔P1与4条电极连接线31耦接。
在一些实施例中，如图3所示，多个第一过孔P1与多个第二过孔P2一一对应，也就是说，一个第一过孔P1对应于一个第二过孔P2。多个第一过孔P1中的每个第一过孔P1在衬底基板1上的正投影与相对应的第二过孔P2在衬底基板1上的正投影至少部分重叠，以使第一过孔P1与相对应的第二过孔P2形成套孔结构P。
基于此，如图3所示，实现公共电极层2中的第一触控电极211与栅电极层3＇中的电极连接线31的电连接，需要在两个膜层之间的第一绝缘层5和第二绝缘层6中制作过孔，而直接制作一个穿透第一绝缘层5和第二绝缘层6这两个绝缘层的过孔，由于孔深较大，因此可能会出现刻蚀不良。上述实施例通过分别制作一个第一过孔P1和与该第一过孔P1相对应的一个第二过孔P2，以形成一个穿透两个绝缘层的套孔结构P，这样可以降低刻蚀难度，并且可提高第一触控电极211与电极连接线31之间的接触良率。
在一些实施例中，如图1所示，每行第一触控电极211对应至少一行套孔结构P。每行套孔结构P中的各套孔结构P，沿第一方向D1排列，且与每行第一触控电极211中的各第一触控电极211分别相对应。
例如，如图1所示，第1行的4个第一触控电极211对应4行套孔结构P。在这4行套孔结构P中，第1行的套孔结构P包括4个套孔结构P。这4个套孔结构P与第1行的4个第一触控电极211一一对应。
同样，第2行、第3行、第4行的套孔结构P中的各行套孔结构P也分别包括4个套孔结构P，这4个套孔结构P也与第1行的4个第一触控电极211一一对应。也就是说，第1行的4个第一触控电极211中的各个第一触控电极211，对应4个位于不同行的套孔结构P。
基于此，如图1所示，将串接每行第一触控电极211的至少一条电极连接线31中，每条电极连接线31沿第一方向D1延伸设置，每条电极连接线31通过该行第一触控电极211对应的一行套孔结构P，与该行第一触控电极211中的各第一触控电极211耦接。
例如，如图1所示，第1条电极连接线31，通过第1行的套孔结构P与第1行的第一触控电极211中的各第一触控电极211耦接。
下面仍以本公开实施例提供的阵列基板02的薄膜晶体管TFT是顶栅型薄膜晶体管为例，对如何将沿第一方向D1排列的每行第一触控电极211与第一触控信号线41耦接进行说明。可以理解的是，本公开的实施例包括但不限于 下述实施例中提供的实现方式。
如图3所示，第二绝缘层6中设有贯通第二绝缘层6的多个第二过孔P2。请参阅图1，每行第一触控电极211通过多个第二过孔P2中的至少一个第二过孔P2与至少一条第一触控信号线41耦接。
示例性的，如图1所示，在每行第一触控电极211中，其中一个第一触控电极211，通过4个第二过孔P2与一条第一触控信号线41耦接，其他第一触控电极211，通过4条电极连接线31与该个第一触控电极211连接。这样，每行第一触控电极211则与一条第一触控信号线41耦接。
以第1行第一触控电极211为例：
第1行第一触控电极211中，处于第2列的第一触控电极211通过4个第二过孔P2与一条第一触控信号线41耦接。又因第1行第一触控电极211被4条电极连接线31串接，这样一来，在触控阶段，可以通过第1行第2列的第一触控电极211所耦接的一条第一触控信号线41，向第1行第2列的第一触控电极211传输第一触控信号S1，再由串接第1行第一触控电极211的这4条电极连接线31，将第一触控信号传输给第1行第一触控电极211的其余各个第一触控电极211，从而实现第1行第一触控电极211与一条第一触控信号线41耦接。
在一些实施例中，如图1所示，每行第一触控电极211中的每个第一触控电极211对应至少一列第二过孔P2，每列第二过孔P2中的各第二过孔P2沿第二方向D2排列。
示例性的，如图1所示，以第1行第2列第一触控电极211为例：
第1行第2列第一触控电极211对应一列第二过孔P2，这列第二过孔P2包括4个第二过孔P2，这4个第二过孔P2沿第二方向D2排列。
图1中以每行第一触控电极211中的每个第一触控电极211对应一列第二过孔P2为例进行示意。在本公开的一些实施例中，每行第一触控电极211中的每个第一触控电极211所对应的第二过孔P2的列数可以是多列，例如2列、3列、4列、5列等。
基于此，请继续参阅图1，将每行第一触控电极211所耦接的至少一条第一触控信号线41中，每条第一触控信号线41沿第二方向D2延伸设置。每条第一触控信号线41，通过该行第一触控电极211中的一个第一触控电极211对应的一列第二过孔P2，与该行第一触控电极211耦接。
示例性的，如图1所示，以第2条第一触控信号线41为例：
第2条第一触控信号线41沿第二方向D2延伸设置，并且通过第1行第 2列的第一触控电极211对应的一列第二过孔P2，与第1行第一触控电极211耦接。
请继续参阅图1，每行第一触控电极211所耦接的至少一条第一触控信号线41中，每条第一触控信号线41，通过该行第一触控电极211中的一个第一触控电极211对应的一列第二过孔P2，与该行第一触控电极211耦接。其中，该个第一触控电极211对应的一列第二过孔P2所在的位置称为该行第一触控电极211的第一触控信号接入点41L。也就是说，第一触控信号接入点41L是每行第一触控电极211所耦接的至少一条第一触控信号线41中，每条第一触控信号线41将第一触控信号S1传输给该行第一触控电极211的位置。也可以说，第一触控信号接入点41L是每行第一触控电极211与每条第一触控信号线41耦接的位置。
例如，如图1所示，以第1行第一触控电极211为例：
第1行第一触控电极211耦接有一条第一触控信号线41。其中，该条第一触控信号线41，通过第1行第2列第一触控电极211对应的一列第二过孔P2，与第1行第一触控电极211耦接。第1行第2列第一触控电极211对应的一列第二过孔P2所述在的位置，即为第1行第一触控电极211的第一触控信号接入点41L。
可以理解的是，每行第一触控电极211所耦接的第一触控信号线41的条数，与每行第一触控电极211的第一触控信号接入点41L的数量一致。
在一些实施例中，每行第一触控电极211所耦接的第一触控信号线41的条数为一条，则每行第一触控电极211的第一触控信号接入点41L的数量为1个。例如，如图1和图5所示，第1行第一触控电极211所耦接的第一触控信号线41的条数为1条，则第1行第一触控电极211的第一触控信号接入点41L的数量为1个。
在一些实施例中，每行第一触控电极211所耦接的第一触控信号线41的条数为两条，则每行第一触控电极211的第一触控信号接入点41L的数量为两个。
在一些实施例中，请参阅图5，各行第一触控电极211的各个第一触控信号接入点41L，在衬底基板1上的正投影的排布呈倒V字形(图5中虚线W1和W2组成的图形)。
下面参考图5，对上述各行第一触控电极211的各个第一触控信号接入点41L，在衬底基板1上的正投影的排布所呈现的“倒V字形”进行说明：
如图5所示，第一触控信号线41包括第一端411和第二端412，其中， 第一端411被配置为与触控芯片01连接。阵列基板02沿第一方向D1延伸的两侧分别为第一侧02A和第二侧02B，其中，在第一触控信号线41延伸方向上，第一端411指向第二端412的方向上，第一侧02A更靠近第一端411。各个第一触控信号接入点41L到阵列基板02的第一侧02A的距离为第一距离h。
沿第一方向D1将阵列基板02均分为两份的均分线称为阵列基板02的中间线W3。各个第一触控信号接入点41L到阵列基板02的中间线W3的距离为第二距离d。
其中，各个第一触控信号接入点41L对应的第二距离d和第一距离h的关系为：第二距离d随着第一距离h的减小而变大。也就是说，各行第一触控电极211的各个第一触控信号接入点41L中，每个第一触控信号接入点41L到阵列基板02的第一侧02A的第一距离h越大，该个第一触控信号接入点41L越靠近阵列基板02的中间线W3；每个第一触控信号接入点41L到阵列基板02的第一侧02A的第一距离h越小，该个第一触控信号接入点41L越远离阵列基板02的中间线W3。这样使得各行第一触控电极211的各个第一触控信号接入点41L，在衬底基板1上的正投影的排布呈倒V字形。
例如，如图5所示，第一行第一触控电极211的第一触控信号接入点41L到阵列基板02的第一侧02A的第一距离h最大，第一行第一触控电极211的第一触控信号接入点41L最靠近阵列基板02的中间线W3。第一行、第二行、第三行、第四行、第五行、第六行、第七行、第八行第一触控电极211的第一触控信号接入点41L到阵列基板02的第一侧02A的第一距离h依次逐渐变小，它们到阵列基板02的中间线W3的第二距离d依次逐渐变大。这样，第一行、第二行、第三行、第四行、第五行、第六行、第七行、第八行第一触控电极211的第一触控信号接入点41L在衬底基板1上的正投影的排布呈倒V字形。这样，各个第一触控信号线41的有效段，即各个第一触控信号线41的各个第一触控信号接入点41L到阵列基板02的第一侧02A之间的这一段，较长的有效段排布在较靠近阵列基板02中间的位置，较短的有效段排布在较远离阵列基板02中间的位置。由此，可以减小在阵列基板02的边缘部分被损坏时，各个第一触控信号线41的有效段被破坏的几率，例如即使左上角和/或右上角被损坏了，也不会切断第一触控信号线41。
如图6、图7a、图7a和图8所示，在本公开的一些实施例中，在第二导电层4设置有沿第二方向D2延伸的多条虚拟触控信号线46。通过设置该多条虚拟触控信号线46，可以减弱各行第一触控电极211的驱动信号衰减和降 低各行第一触控电极211的检测信号失真率，进而提高触控阶段触控位置定位的准确性。
下面仍以本公开实施例提供的阵列基板02的薄膜晶体管TFT是顶栅型薄膜晶体管为例，对如何通过在第二导电层4设置沿第二方向D2延伸的多条虚拟触控信号线46，提高触控阶段触控位置定位的准确性的这些实施例进行说明。
在一些实施例中，如图8所示，多条虚拟触控信号线46与多条第一触控信号线41和多条第二触控信号线42同层设置于第二导电层4。如图7a、图7a所示，各条虚拟触控信号线46与各条第一触控信号线41和各条第二触控信号线42相互平行设置。
可以理解的是，各条第一触控信号线41、各条第二触控信号线42、各源极43、各漏极44各条数据线45以及各条虚拟触控信号线46之间相互电性绝缘。
如图8所示，第一导电层3与第二导电层4之间设置有第一绝缘层5，第一绝缘层5中设有贯通第一绝缘层5的多个第一过孔P1。请参阅图6，每行第一触控电极211中的每个第一触控电极211对应至少一列第一过孔P1，每列第一过孔P1中的各第一过孔P1沿第二方向D2排列。
请参阅图6、图7a、图7a和图8，第二导电层4还包括沿第二方向D2延伸的多条虚拟触控信号线46。如图6所示，每行第一触控电极211中，除与至少一条第一触控信号线41耦接的第一触控电极211外，其它每个第一触控电极211对应至少一条虚拟触控信号线46。
请继续参阅图6，至少一条虚拟触控信号线46中的每条虚拟触控信号线46，通过其对应的第一触控电极211所对应的一列第一过孔P1，将经过该列第一过孔P1的各电极连接线31电性连通。
这样一来，多条虚拟触控信号线46、多条电极连接线31以及多条第一触控信号线41形成一个电性连通的网络，该网络的交汇点(位于P指向的点)分布于各行第一触控电极211的各第一触控电极211上。在触控阶段，第一触控信号S1通过该网络传输至各行第一触控电极211的各第一触控电极211。从而使得各第一触控电极211电阻减小，进而减弱各行第一触控电极211的驱动信号衰减和降低各行第一触控电极211的检测信号失真率，以此提高了触控位置定位的准确性。
例如，以第1行第一触控电极211为例：
第1行第一触控电极211中，除与一条第一触控信号线41耦接的第2列 第一触控电极211外，其它3个第一触控电极211中的每个第一触控电极211对应1条虚拟触控信号线46。其中，每条虚拟触控信号线46，通过其对应的第一触控电极211所对应的一列第一过孔P1，将经过该列第一过孔P1的各电极连接线31电性连通。
例如，第1列第一触控电极211对应1条虚拟触控信号线46，且该第一触控电极211对应一列第一过孔P1，该列第一过孔P1包括4个第一过孔P1。该条虚拟触控信号线46，将经过该4个第一过孔P1的4条电极连接线31(即，上起第1条、第2条、第3条、第4条电极连接线31)电性连通。
同样，第1行第一触控电极211中，第3列、第4列的第一触控电极211也分别对应的一条虚拟触控信号线46，这两条虚拟触控信号线46也将该4条电极连接线31电性连通。
这样一来，第1行第一触控电极211所对应的3虚拟触控信号线、4条电极连接线31，以及1条第一触控信号线41形成一个电性连通的网络，该网络的交汇点分布于第1行第一触控电极211的各第一触控电极211上。在触控阶段，第一触控信号S1通过该网络传输至第1行第一触控电极211的各第一触控电极211。
在一些实施例中，如图6所示，多条虚拟触控信号线46为多条不与触控芯片01连接的第一触控信号线41,且多条虚拟触控信号线46中的至少一条虚拟触控信号线46具有多处断口E。即，多条虚拟触控信号线46与多条第一触控信号线41的区别在于多条第一触控信号线41与触控芯片01连接，而多条虚拟触控信号线43不与触控芯片01连接，并且多条虚拟触控信号线46中的至少一条虚拟触控信号线43具有多处断口E。
在另外一些实施例中，多条虚拟触控信号线43不与触控芯片01电连接，即，多条虚拟触控信号线46中的各条虚拟触控信号线46不具有断口E。
在本公开的实施例中，多处断口E的位置至少包括但不限于以下三种情形：
一、如图6所示，多处断口E中的至少一处断口E在衬底基板1上的正投影位于沿第二方向D2的相邻两个第一触控电极211在衬底基板上的正投影之间。即，多处断口E中的至少一处断口E在沿第二方向D2的相邻两个第一触控电极211之间。也可以说，多条虚拟触控信号线46中的至少一条虚拟触控信号线46，在沿第二方向D2的相邻两个第一触控电极211之间断开。例如，如图6所示，第1条虚拟触控信号线46，在第1行第1列的第一触控电极211，与第2行第1列的第一触控电极211之间断开。
可以理解的是，当第2行第1列的第一触控电极211上加载有第一触控信号S1时，与其耦合的虚拟触控信号线46上也加载有第一触控信号S1，如果该条虚拟触控信号线46，在第1行第1列的第一触控电极211，与第2行第1列的第一触控电极211之间不断开，则加载有第一触控信号S1的该条虚拟触控信号线46将会对第1行第1列的第一触控电极211造成影响，容易引起第1行第一触控电极211与第2行第一触控电极211之间的信号串扰，影响触控位置定位的准确性。。
二、如图6所示，多处断口E中的至少一处断口E在衬底基板1上的正投影位于沿第二方向D2的相邻的一个第一触控电极211和一个第二触控电极212在衬底基板1上的正投影之间。即，多处断口E中的至少一处断口E在沿第二方向D2的相邻的一个第一触控电极211和一个第二触控电极212之间，也就是说，多条虚拟触控信号线46中的至少一条虚拟触控信号线46，在沿第二方向D2的相邻的一个第一触控电极211和一个第二触控电极212之间断开。例如，如图6所示，第一条虚拟触控信号线46，在第2行第1列的第一触控电极211，与第3行第1列的第二触控电极212之间断开。
可以理解的是，在触控阶段，第2行第1列的第一触控电极211上所加载的第一触控信号S1，与第3行第1列的第二触控电极212上所加载的第二触控信号S2为两种不同种类的信号。这两种不同种类的信号，一者为驱动信号，另一者为感应信号。如果该条虚拟触控信号线46，在第2行第1列的第一触控电极211，与第3行第1列的第二触控电极212之间不断开，则第2行第1列的第一触控电极211上所加载的第一触控信号S1，与第3行第1列的第二触控电极212上所加载的第二触控信号S2之间容易相互干扰，影响触控位置定位的准确性。
三、多处断口E中的至少一处断口E在衬底基板1上的正投影位于沿第二方向D2的相邻两个第一触控电极211在衬底基板1上的正投影之间。并且，多处断口E中的至少一处断口E在衬底基板1上的正投影位于沿第二方向D2的相邻的一个第一触控电极211和一个第二触控电极212在衬底基板1上的正投影之间。
下面仍以本公开实施例提供的阵列基板02的薄膜晶体管TFT是顶栅型薄膜晶体管为例，对如何实现每个第二触控电极212或沿第二方向D2排列的每列第二触控电极212与第二触控信号线42耦接进行说明。可以理解的是，本公开的实施例包括但不限于下述实施例中提供的实现方式。
在一些实施例中，如图8所示，第二绝缘层6中设有贯通第二绝缘层6 的多个第三过孔P3。请参阅图6，每个第二触控电极212通过多个第三过孔P3中的至少一个第三过孔P3与至少一条第二触控信号线42耦接。
请继续参阅图6，在一些实施例中，每个第二触控电极212对应至少一列第三过孔P3，每列第三过孔P3中的各第三过孔P3沿第二方向D2排列。
基于此，将每个第二触控电极212所耦接的至少一条第二触控信号线42中，每条第二触控信号线42沿第二方向D2延伸设置。每条第二触控信号线42通过该第二触控电极212对应的一列第三过孔P3，与该第二触控电极212耦接。
例如，如图6所示，第4行第1列第二触控电极212耦接有一条第二触控信号线42，该条第二触控信号线42沿第二方向D2延伸设置。第4行第1列第二触控电极212对应一列第三过孔P3，该列第三过孔P3包括4个第三过孔P3，这4个第三过孔P3沿第二方向D2排列。该条第二触控信号线42通过该4个第三过孔P3，与第4行第1列第二触控电极212耦接。
可以理解的是，如图9所示，本公开实施例提供的阵列基板具有触控区域021，和位于触控区域021至少一侧的周边区域022。例如，在一些实施例中，如图9所示，周边区域022位于触控区域021沿第二方向D2的下侧。
请继续参阅图9，在一些实施例，每列第二触控电极212所耦接的各第二触控信号线42在周边区域022相互耦接，以使每列第二触控电极212串接。
例如，如图9所示，第1列第二触控电极212中的两个第二触控电极212，分别耦接有一条第二触控信号线42，这两条第二触控信号线42在周边区域022相互耦接，以使第1列第二触控电极212中的两个第二触控电极212串接在一起。
在一些实施例中，如图8所示，第二绝缘层6中设有贯通第二绝缘层6的多个第三过孔P3。请参阅图10，每列第二触控电极212通过多个第三过孔P3中的至少一个第三过孔P3与至少一条第二触控信号线42耦接。
图10以每列第二触控电极212通过多个第三过孔P3中的8个第三过孔P3与一条第二触控信号线42耦接为例进行示意，可以理解的是，本公开的实施例包括但不限于此。
请继续参阅图10，每列第二触控电极212对应至少一列第三过孔P3，每列第三过孔P3中，各第三过孔P3沿第二方向D2排列，且各第三过孔P3与每列第二触控电极212中的各第二触控电极212分别相对应。每列第二触控电极212所耦接的至少一条第二触控信号线42中，每条第二触控信号线42沿第二方向D2延伸。每条第二触控信号线42通过该列第二触控电极212对 应的一列第三过孔P3，与该列第二触控电极212耦接。
例如，如图10所示，以第1列第二触控电极212为例：
第1列第二触控电极212对应一列第三过孔P3，其中，该列第二触控电极212包括两个第二触控电极212，该列第三过孔P3包括8个第三过孔P3。该两个第二触控电极212中的各个第二触控电极212对应4个第三过孔P3。该列第二触控电极212耦接有一条第二触控信号线42，该条第二触控信号线42沿第二方向D2延伸。该条第二触控信号线42通过上述8个第三过孔P3，与第1列第二触控电极212耦接。
请参阅图11和图12，在一些实施例中，多个公共电极21中的一部分公共电极21被复用为第一触控电极211，形成了多个第一触控单元X。多个公共电极21中的另一部分公共电极21被复用为第二触控电极212，形成了多个第二触控单元Y。
请继续参阅图11，在一些实施例中，多个第一触控单元X中的每个第一触控单元X包括至少一个第一触控电极211；以及多个第二触控单元Y中的每个第二触控单元Y包括至少一个第二触控电极212。
示例性的，如图11所示，24个公共电极21中，12个公共电极21被复用为第一触控电极211，形成了3个第一触控单元X，这3个第一触控单元X中各个第一触控单元X包括4第一触控电极211。24个公共电极中，12个公共电极21被复用为第二触控电极212，形成了3个第二触控单元Y，这3个第二触控单元Y中各个第二触控单元Y包括4个第二触控电极212。
本公开提供的实施例，关于第一触控单元X和第二触控单元Y的布置方式，包括但不限于以下三种方式：
一、如图12所示，在一些实施例中，沿第一方向D1，第一触控单元X和第二触控单元Y交替布置。
二、如图12所示，在一些实施例中，沿第二方向D2，第一触控单元X和第二触控单元Y交替布置。
三、如图12所示，在一些实施例中，沿第一方向D1，第一触控单元X和第二触控单元Y交替布置；以及沿第二方向D2，第一触控单元X和第二触控单元Y交替布置。这样，可以使得第一触控单元X和第二触控单元Y在整个触控区域内均匀分布，从而提高触控效果。
在一些实施例中，第一触控单元X包括2～8个第一触控电极211；第二触控单元Y包括2～8个第二触控电极212。图12仅以第一触控单元X包括4个第一触控电极211，第二触控单元Y包括4个第二触控电极212为例进行 示意。
在一些实施例中，如图11和图12所示，阵列基板02的触控区域021被划分为多个子区域F，多个子区域F中的每个子区域F内布置有两个第一触控单元X和两个第二触控单元Y；每个第一触控单元X包括四个第一触控电极211，每个第二触控单元Y包括四个第二触控电极212。
也就是说，如图11和图12所示，在阵列基板的触控区域021，多个公共电极21中的16个公共电极21被划分为一个子区域F，形成多个子区域F。这16个公共电极21中的8个被复用为第一触控电极211，形成两个第一触控单元X，每个第一触控单元X包括四个第一触控电极211。这16个公共电极21中的8个被复用为第二触控电极212，形成两个第二触控单元Y，每个第二触控单元Y包括四个第二触控电极212。
即，在阵列基板的触控区域021，多个公共电极21中的16个公共电极21为一组进行设计。当然也可以是其他个数为一组进行设计，例如15个公共电极21为一组进行设计，17个公共电极21为一组进行设计，18个公共电极21为一组进行设计。
在一些实施例中，第一触控单元X和第二触控单元Y相邻的区域边界可以不完全是直线空隙，例如设置为相互咬合的曲线或者折线边界，这样可以形成更好的触控效果。
在本公开的实施例中，多个公共电极中的各公共电极(即各第一触控电极211和第二第二触控电极212)的形状包括多种形状，例如正方形，矩形、菱形、多边形等。在上述实施例以及下述实施例中，仅以多个公共电极中的各公共电极的形状为正方形为例进行示意，可以理解的是，在本公开的实施例包括但不限于此。
在本公开的实施例中，多个公共电极中的各公共电极(即各第一触控电极211和第二第二触控电极212)的形状相同。或者，多个公共电极中至少一个公共电极的形状与多个公共电极中其他公共电极的形状不相同。
在本公开的实施例中，多个公共电极中的各公共电极(即各第一触控电极211和第二第二触控电极212)的大小相同。或者，多个公共电极中至少一个公共电极的大小与多个公共电极中其他公共电极的形状不相同。
在本公开的实施例中，多个第一触控电极211中的各第一触控电极211的形状，与多个第二触控电极212中的各第一触控电极212的形状相同。例如，如图3所示，多个第一触控电极211中的各第一触控电极211的形状，以及多个第二触控电极212中的各第一触控电极212的形状均为正方形或矩 形或菱形。或者，多个第一触控电极211中的各第一触控电极211的形状，与多个第二触控电极212中的各第一触控电极212的形状不相同。
在本公开的实施例中，多个第一触控电极211中的各第一触控电极211的大小，与多个第二触控电极212中的各第一触控电极212的大小相等。例如，如图3所示，多个第一触控电极211中的各第一触控电极211的形状，与多个第二触控电极212中的各第一触控电极212的大小相等。或者，多个第一触控电极211中的各第一触控电极211的大小，与多个第二触控电极212中的各第一触控电极212的大小不相等。
如图13所示，本公开的实施例还提供一种触控显示装置1A，该触控显示装置1A包括上述任一实施例的阵列基板02，以及触控芯片01。
请参阅图1，触控芯片01与阵列基板02的多条第一触控信号线41和多条第二触控信号线42耦接。触控芯片01被配置为，向多条第一触控信号线41中的每条第一触控信号线41提供进行触摸位置检测所需的第一触控信号S1，向多条第二触控信号线42中的每条第二触控信号线42提供进行触摸位置检测所需的第二触控信号S2。

示例性的，该对向基板03可以为彩膜基板；或者，当该阵列基板02为COA(color filter on array)型阵列基板时，即阵列基板02上制作有彩色滤色膜时，对向基板03可以为盖板，例如为盖板玻璃(Cover glass)。
在上述触控显示装置1A为液晶显示装置的情况下，在上述阵列基板02中，每个子像素均包括有像素电极和公共电极，该阵列基板02与对向基板03对盒封装形成液晶显示装置所包括的液晶显示面板后，该液晶显示面板可以为AD-SDS型(Advanced-Super Dimensional Switching，高级超维场开关)面板，通过位于阵列基板02侧的像素电极与公共电极之间产生的边缘电场，使电极间以及电极上方的取向液晶分子都能在平行于显示面板显示面的平面方向内发生偏转，从而可在增大视角的同时提高液晶层的透光效率。
上述触控显示装置1A还可包括提供背光的背光模组、驱动电路部分等，具体结构此处不再赘述。
