附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明阵列基板的结构示意图；
图2是图1所示A的放大示意图；
图3是仿真实验结果曲线图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动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。
请参阅图1所示，本发明的阵列基板100包括衬底10、多条栅极线20、多个触控电极30、多条第二触控引线32和触控驱动单元50。所述多条栅极线20沿第一方向X排列。所述多个触控电极30阵列排布于所述衬底10上，每个触控电极30均通过各自对应的第二触控引线32连接至所述触控驱动单元50。触控驱动单元50在触控时段为对应触控电极30提供触控感测信号，在显示时段为对应触控电极30提供公共电压，并通过第二触控引线32传输至与其对应的触控电极30上。
请结合参阅图2，本发明中将每个触控电极30分割为多个呈条状的子电极33，所述多个子电极33在第二方向上间隔排列，所述第二方向与所述第一方向X相互垂直。第二方向每个子电极33的延伸方向与所述栅极线20的延伸方向相同。同一触控电极30中的多个子电极33之间通过第一触控引线31电性连接。所述栅极线20在所述触控电极30上的投影位于两个所述子电极30之间的间隔中。
为验证本发明的技术效果，本发明中以5.5”的触控显示屏进行估算，定义C1为触控电极对栅极线的电容，C2为第二触控引线对栅极线的电容，C3为其他的电容(包含触控电极对数据线、第二触控引线对数据线及触控电极间侧向电容之和)，R1为第二触控引线的电阻，如下表所示：
Figure PCTCN2016090607-appb-000001
请参阅图3，图3为将上述参数输入仿真软件的模拟仿真结果，a图为现有技术模拟结果，现有技术中触控电极为整片相连时，其响应时间为2.71us；b图为本发明设计方案的模拟结果，本发明中由于触控电极对栅极线的电容C1＝0，其仿真的响应时间缩短为2.25us。从图3中可以看出，本发明设计方案相对于现有技术的触控响应时间明显下降。本发明在不改变制程、不增加光 罩数量的情况下，将电容的负载(C Loading)降低，同时缩短了响应时间，提升触控灵敏度，改善了触控性能。
综上，本发明中将触控电极切割为多个间隔分布的子电极，栅极线在触控电极上的投影位于子电极之间的间隔中，从而使触控电极避开栅极线，在不改变触控电极大小的情况下，减小栅极线对触控电极之间的电容，进而减小触控时其他信号造成的干扰，提高了触控灵敏度，缩小了触控响应时间。
进一步具体的，请继续参阅图2，本发明的一个实施例中，所述第一触控引线31与所述子电极33设置于不同导电层中，因此在每个所述子电极33上均设置有过孔34，所述第一触控引线31与所述子电极33之间通过所述过孔34电性连接。更进一步的，每个所述子电极33上均设置有多个过孔34，所述多个过孔34沿第一方向X均匀排列。也就是说，所述触控电极30中包括阵列设置的多个过孔34。每个触控电极30中同一列的所述过孔34通过同一第一触控引线31电性连接。换而言之，每个触控电极30中，垂直于第一方向X(即第二方向)的多个过孔34之间通过同一所述第一触控引线31连接。可以理解的是，所述第一触控引线31的数量为多条，多条所述第一触控引线31沿所述第二方向延伸。
可以理解的是，本发明实施例对于触控电极30的大小和形状，以及触控电极30内子电极33的数量等均不做具体限制。例如，图2中触控电极30分为5个子电极33，这只是本申请所有实施例中的一种，本发明对此不作限制。
可以理解的是，每条子电极33上过孔34的数量也不作具体的限定。显而易见的，过孔的数量越多，其触控的灵敏度也就越高，相应的布线越复杂，制造成本也就越高。
本发明一个具体的实施例中，每个触控电极30中不相邻的两条所述第一触控引线31共同连接至同一所述第二触控引线32上，从而通过所述第二触控引线32将触控电极连接至所述触控驱动单元50。可以理解的是，与所述第二触控引线32相连接的第一触控引线31的数量越多，触控就越稳定，但是所需要的布线也就越多，成本也会随之上升。本实施例中，设置两条第一触控引线31不相邻也是为了提高触控的稳定性。
可以理解的是，本发明中多条第一触控引线31和多条第二触控引线32的 材料可以采用金属线，同时为了保证传输信号的效果保持一致，本发明实施例优选的所有触控引线的电阻相同。
本发明一个具体的实施例中，所述栅极线20和所述触控电极30设置于不同导电层，其中，所述栅极线20所在的导电层位于所述触控电极30所在的导电层的下方。具体的，在同一触控电极30中，每条栅极线20各自对应一个子电极33。
本发明中可以将第一触控引线31、多条第二触控引线32和所述栅极线20设置在同一导电层中。
本发明还提供一种触控显示屏，包括相对设置的彩膜基板和阵列基板，所述阵列基板为上述任意一种所述的阵列基板100。所述触控显示屏可以应用于包括但不限于为：电子纸、液晶电视、移动电话、数码相框、平板电脑等任何具有触控显示功能的产品或部件。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
