目前，一种电容式内嵌触摸屏可通过在薄膜场效应晶体管(Thin Film Transistor，简称TFT)阵列基板上直接另外增加触控扫描线和触控感应线实现。在TFT阵列基板的表面制作两层相互异面相交的条状铟锡氧化物(Indium Tin Oxide，简称ITO)电极，这两层(ITO)电极分别作为触摸屏的触控驱动线和触控感应线，感应电容在两条ITO电极的异面相交处形成。该电容式内嵌触摸屏的工作过程为：在对作为触控驱动线的ITO电极加载触控驱动信号时，检测触控感应线通过感应电容耦合出的电压信号，在此过程中，如有人体接触触摸屏时，人体电场就会作用在感应电容上，使感应电容的电容值发生变化，进而改变触控感应线耦合出的电压信号。因此，根据电压信号的变化，就可以确定触点位置。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发 明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
发明人认识到，当前的电容式内嵌触摸屏的结构设计需要在TFT阵列基板上增加新的膜层，导致在制作TFT阵列基板时需要增加新的工艺，使生产成本增加，不利于提高生产效率。
图1为本发明一实施例提供的阵列基板的结构示意图，如图1所示，本实施例中的阵列基板包括：公共电极层102和像素电极层103；在图示的实施例中，公共电极层102形成在像素电极层103之上。
图2为图1中触控感应电极和触控驱动电极的分布示意图，公共电极层102包括触控驱动电极104，触控驱动电极104连接信号连接端(未示出，例如为触控驱动器)，所述信号连接端在包括该阵列基板的触控显示装置的显示阶段输出公共电平，且在触控阶段为高阻态。公共电极层102可以整层被划分为触控驱动电极，也可以部分被划分为触控驱动电极；如图2所示的示例中，公共电极层102包括纵向延伸的触控驱动电极104和横向延伸的公共电极条102a，该公共电极条102a与触控感应电极105对应，将其两侧的触控驱动电极104分隔开。
图3为图1中触控感应电极与像素电极的分布示意图，像素电极层103包括像素单元的像素电极106和触控感应电极105，触控感应电极105形成在两行相邻的像素电极106之间。
如图2所示，触控感应电极(Rx)105与触控驱动电极(Tx)104呈交叉设置。
在本发明至少一实施例中，为提高包含上述阵列基板的触控显示装置的触控效果，可使触控感应电极105与触控驱动电极104彼此垂直分布。
本发明的实施例不限于上述图示的示例，例如，也可以触控驱动电极104沿横向分布，而触控感应电极105沿纵向分布。
应说明的是，在具体应用中，前述的信号连接端可连接到驱动芯片，由此驱动芯片在显示阶段使信号连接端输出公共电平，且在触控阶段呈现高阻态。
在本发明至少一实施例中，所述触控感应电极105和像素电极106同层分开设置，且触控感应电极105和像素电极106之间不连接，即电绝缘。
在本发明至少一实施例中，公共电极层位于阵列基板的阵列基底101上，且公共电极层和像素电极层之间设置有保护层(绝缘层)，如图1所示。
本发明至少一实施例中的阵列基板中将触控驱动电极作为公共电极层的一部部分，触控感应电极作为像素电极层的一部分，因此，使用已知的触摸屏的工艺可以实现触控和显示的双重功能，可减少包含阵列基板的触控显示装置的制作成本，同时提高包含阵列基板的触控显示装置的生产效率。
本发明至少一实施例中，可使公共电极层中的触控驱动电极104为分隔排列的条状电极，如图2所示，公共电极层的部分结构为分隔排列的条状电极104a。例如，图2中所示的所有分隔排列的条状电极104a的宽度均相等，但是本发明的实施例不限于此。
为更好的说明触控感应电极和触控驱动电极的位置关系，图2中示出触控感应电极的相对位置关系，即，在公共电极层102的上方形成有与公共电极层102绝缘的例如ITO电极作为触控感应电极105，该触控感应电极105位于像素电极的周边，且与栅极线/源极线平行。该公共电极层102中与触控感应电极105对应的横向延伸部分102a，将两侧的条状电极104a间隔开，该横向延伸部分102a例如在显示时间段和触控时间段都被施加公共电压，作为公共电极。使用该公共电极隔离触控驱动电极和触控感应电极可以减少触控驱动电极和触控感应电极的互电容，可以提高触控的灵敏度。
如图3所示，每个触控感应电极105位于两行相邻的像素电极106之间，即沿着与栅极线平行的方向。在具体应用中，触控感应电极105与栅极线/源极线相互绝缘。本发明至少一实施例中的触控感应电极例如由氧化铟锡制成。
另外，结合图2和图3所示，每个触控感应电极105位于两行相邻的像素电极之间，而在触控显示装置中，对置基板(例如彩膜基板)的黑矩阵的位置对应于像素电极的周边，故在本发明至少一实施例中，触控感应电极105可位于黑矩阵115下方，如图5所示。也就是说，在像素电极周边增加横向电极(如图2所示的横向电极)作为触控感应电极。
本发明至少一实施例中的阵列基板可实现触控和显示的双重功能，进而 可减少包含阵列基板的触控显示装置的制作成本，提高触控显示装置的生产效率。
在本发明至少一实施例中，还可将公共电极层的触控驱动电极区域设置用于使多个触控驱动电极导通的过孔107，如图2所示。
结合图2和图4进行说明如下。在图4中，将相邻两列像素单元作为一像素单元组，相邻两列像素单元共用一条位于该两列像素单元之间的数据信号线109；相邻像素单元组之间设置有与所述数据信号线109平行的导电线108，每条导电线108通过过孔连接到一个触控驱动电极104。在另一个示例中，在相邻两行像素单元之间设置两条分别驱动这两行像素单元的栅线，由此构成双栅结构。
在本发明至少一实施例中，导电线可通过过孔将公共电极层102中位于同一列的多个条状电极导通，条状电极与触控感应电极的垂直分布。也就是说，公共电极层102中属于同一列的条状电极104a通过过孔107连接，且属于同一列的条状电极104a与所述触控感应电极105呈交叉设置。例如，属于同一列的条状电极可如图2的虚线框中的条状电极。
在本发明至少一实施例中，每条导电线108可通过至少一个(例如多个)过孔107与一个触控驱动电极104连接，和/或，一个触控驱动电极104连接到多条导电线108。
应说明的是，本发明至少一实施例中的数据信号线109和导电线108同层设置。如图4所示，本实施例中的导电线108与数据信号线109间隔分布，可减少数据信号线的数目。
在减少的数据信号线的地方增加导电线(如虚拟源极线)，可降低触控驱动电极的电阻电容(Resistance Capacitance，简称RC)负载，进而可以提高包含阵列基板的触控显示装置的触控效果，保证了触控所需的精度。
上述的过孔107可为金属凸起结构，方便与导电线电连接。
在本发明的至少一个实施例中，相邻行的像素单元之间具有两条栅极信号线。前述的像素单元可包括薄膜晶体管、包括像素电极的像素电极层和公共电极层，所述薄膜晶体管依次包括栅极、设置于所述栅极之上的栅绝缘层、设置于所述栅绝缘层之上有源层、设置于所述有源层之上的源极和漏极、以及设置于所述源极和漏极之上的钝化层等。通常，所述公共电极层直接设置 在所述钝化层之上，所述像素电极层设置在所述钝化层之下，并与所述薄膜晶体管的漏极相连接。在本实施例中，像素单元的层结构可以采用已知的结构，这里不对其进行详述。
本发明至少一实施例的阵列基板通过将公共电极层的一部分作为触控驱动电极，在像素电极的周边增加触控感应电极，由此可降低制备触摸屏的阵列基板的工艺，同时实现显示和触控的双重功能，进而可有效的减少包含阵列基板的触控显示装置的制作成本。
