进一步地，所述第二触控电极图形结构15包括第二子图形结构151，所述第二子图形结构151包括第二主体1513及分支1514。本实施方式中，所述第一主体1413沿第一方向(例如图1中X方向)延伸，所述第二主体1513沿不同于所述第一方向的第二方向(例如图1中Y方向)延伸。图1中仅示例性出几个第一子图形结构141及几个第二子图形结构151。
由于所述第二子图形结构151包括第二主体1513及与所述第二主体1513相连的分支1514，在不增加第一触控电极图形结构14与第二触控电极图形结构15的重叠点的情况下，增加的分支1514能够提供额外的感应量(ΔCm)，亦能够提高触控结构100的电容变化率(ΔCm/Cm)，从而进一步提高触控结构100及触控显示装置10的触控效果。
在一具体实施例中，请参阅图2，所述触控显示装置10还包括基板11、阳极层12、发光层13、阴极层17、封装层18及衬底19。所述基板11设置于所述衬底19上。所述基板11为薄膜晶体管阵列基板。阳极层12、发光层13、阴极层17及封装层18依次层叠设置于所述基板11。所述阳极层12图形化设置于所述基板11上，所述阴极层17图形化设置于所述发光层13上，所述第一触控电极图形结构14设置于所述阴极层17的间隙，所述第二触控电极图形结构15设置于所述封装层18上。所述封装层18亦作为所述第一触控电极图形结构14与所述第二触控电极图形结构15之间的绝缘层，从而使所述第一触控电极图形结构14与所述第二触控电极图形结构15相互电性绝缘。所述第一触控电极图形结构14为触控驱动电极(Tx，transport)，所述第二触控电极图形结构15为触控感应电极(Rx，receive)。
所述发光层13包括多个间隙130(如图1所示)，从而形成多个相互间隔设置的像素131(如图1所示)，所述第一触控电极图形结构14与所述第二触控电极图形结构15对应所述发光层13的间隙130设置。请再次参阅图1，所述第一触控电极图形结构14与所述第二触控电极图形结构15异面围成多个像素区101，每个像素区101至少设置一个像素131。由于所述第一触控电极图形结构14、所述第二触控电极图形结构15避开像素131设置，如此能够提 高所述触控显示装置10的光学效果，从而提高所述触控显示装置10的显示品质。
第一子图形结构141在基板11上的正投影与第二子图形结构151在基板11上的正投影的交叠面积为零。所述第一触控电极图形结构14与所述第二触控电极图形结构15异面绕每个像素131形成绕设图形106，即绕设图形106围成像素区101。所述绕设图形106至少包括一个缺口1061，即绕设图形106为非封闭图形，在增加所述触控显示装置10的触控面积的同时，能够提高光的透光量，从而提高所述触控显示装置10的光学效果。可以理解，第一触控电极图形结构14与第二触控电极图形结构15绕至少一个像素131形成绕设图形106，绕设图形106包括至少一个缺口1061。
更为具体的，请参阅图3，第一触控电极图形结构14还包括第一连接布线143。多个第一子图形结构141彼此分开且呈阵列排布。多个第一子图形结构141的第一主体1413通过第一连接布线143与触控显示装置10的主板电连接。
请参阅图4，第二触控电极图形结构15还包括第二连接布线153。多个第二子图形结构151彼此分开。多个第二子图形结构151通过第二连接布线153与触控显示装置10的主板电性连接。设触控显示装置10中的多个第一子图形结构141及多个第二子图形结构151所在区域为触控活动区，本实施方式中，第一连接布线143在所述触控活动区沿所述第二方向延伸，第二连接布线153在所述触控活动区沿所述第一方向延伸。
请再次参阅图3，所述第一子图形结构141的分支1414包括第一分支1415、第二分支1417及第三分支1419。第一分支1415的第一端与第一主体1413连接，所述第二分支1417由所述第一分支1415的第二端弯折延伸。第三分支1419的一端与第一主体1413连接。第三分支1419与第一分支1415分别位于第一主体1413的两侧。本实施方式中，第一分支1415与第一主体1413的连接点与第三分支1419与第一主体1413的连接点相同。于其他实施例中，第一分支1415与第一主体1413的连接点与第三分支1419与第一主体1413的连接点可以不相同。
进一步地，像素区101包括第一像素区1011及第二像素区1013。第一主体1413、第一分支1415及与所述第一分支1415连接的第二分支1417围成第 一像素区1011。第一主体1413、第三分支1419围成第二像素区1013。
可以理解，第一子图形141可以省略第三分支1419，以方便设置于第一触控电极图形结构14的边缘区域的第一子图形结构141布线。
其中，第一像素区1011通过第一主体1413部分、一个第一分支1415及一个第二分支1417围成；第二像素区1013通过第一主体1413部分及一个第三分支1419围成。
本实施方式中，第一方向X与第二方向Y大致相互垂直，第一分支1415与第三分支1419沿第二方向Y延伸，第二分支1417沿第一方向X延伸，第二分支1417与第一主体1413大致平行设置。本实施方式中，每个第一子图形结构141的第一分支1415的数量为三个，三个第一分支1415沿所述第一方向间隔设置，每个第一子图形结构141的第二分支1417的数量对应第一分支1415的数量。每个第一子图形141的第二分支1417与其第一主体1413之间设置一个像素131。第一连接布线143与第一主体1413的一个端点连接，第一连接布线143及三个第一分支1415间隔排列。可以理解，第一子图形141还包括第四分支(图未示)，所述第四分支与所述第三分支1419远离第一主体1413的端部相接，以增加触控线路，从而增加感应量，所述第四分支与第二分支1417可以平行设置。
请参阅图4，每个第二子图形结构151包括一个第二主体1513及分支1514。所述第二主体1513沿所述第二方向Y延伸。分支1514由第二主体1513的一端弯折形成。所述第一分支1415与所述第二主体1513平行设置。所述分支1514与所述第一主体1413平行设置。所述第二主体1513的长度可以依据布线需求进行设定。第二连接布线153可以与第二主体1513交叉连接。
请再次参阅图1，从触控显示装置10的俯视图显然可得，第二子图形结构151的分支1514位于第一像素区1011所在区域，第二子图形151的第二主体1513可以设置在第一像素区1011所在区域，第二主体1513亦可以从第一像素区1011所在区域延伸进入与所述第一像素区1011相邻的第二像素区1013所在区域。
本实施方式中，相邻的像素131之间排布一条、两条或多条线路，增加了触控显示装置10的触控面积，从而提高触控显示装置10的感应量。
请进一步参阅图5与图6，所述第一触控电极图形结构14与所述第二触控电极图形结构15异面交错从而形成交错区域107，所述第一触控电极图形结构14在所述交错区域107的线宽小于所述第一触控电极图形结构14在其余区域的线宽。所述第二触控电极图形结构15在所述交错区域107的线宽小于所述第二触控电极图形结构15在其余区域的线宽。
具体的，第一连接布线143与第二连接布线153异面交错形成交错区域107，第一连接布线143在所述交错区域107的线宽小于第一连接布线143在其余区域的线宽，第二连接布线153在所述交错区域107的线宽小于第二连接布线153在其余区域的线宽。可以理解，不限定第一连接布线143的数量与第二连接布线153的数量及排布方式，不限定第一连接布线143与第二连接布线153的异面交错数量。
交错区域107无法与手指作用，故交错区域107为触控显示装置10的无效触控区域。所述第一触控电极图形结构14与所述第二触控电极图形结构15的非交错区域为触控显示装置10的有效互容区。将所述第一触控电极图形结构14在所述交错区域107的线宽小于所述第一触控电极图形结构14在其余区域的线宽，相当于所述第一触控电极图形结构14在交错区域107作缩小设计从而了减少了Cm(互电容)的背景值，增大了所述有效互容区的ΔCm的感应量，进而提高了电容变化率(ΔCm/Cm)。
可以理解，第一触控电极图形结构14与所述第二触控电极图形结构15的图形(即布线结构)可以互换。
可以理解，所述基板11可以省略，换而言之，触控结构100可以直接安装于需触控功能的设备，从而方便更换，所述基板11可以不为阵列基板，所述基板11可以设置为其他基板，例如，所述基板为绝缘材料制成的基板。
请参阅图7，本发明第二实施方式提供一种触控显示装置30。所述触控显示装置30与所述触控显示装置10的结构大致相似，不同在于，所述第一触控电极图形结构34与所述第二触控电极图形结构35的布线排布。

通过于第一子图形341的第一主体3413设置分支3414，于至少一个第二子图形35的第二主体3513设置分支3514，而第一触控电极图形结构34与第二触控电极图形结构35的重叠点维持不变(图7所示为6点)，通过增加的分支提供额外的ΔCm。在Cm值基本不变情况下，ΔCm增大，从而提高了ΔCm/Cm值。
所述第一触控电极图形结构34与所述第二触控电极图形结构35异面围成多个像素区601(如图7所示)。每个像素361周侧的绕设图形为非封闭图形，在增加所述触控显示装置30的触控面积的同时，能够提高光的透光量，从而提高所述触控显示装置30的光学效果。
