触摸屏按工作原理可以分为电阻式和电容式两种。目前，电容式触摸屏在电子产品上的应用日益普及。电容式触摸屏是利用人体的电流感应进行工作的，是一种通过电极和人体特性结合来感应触摸信号的触摸屏。在人体(手指)触摸屏幕时，由于人体电场作用，手指与触摸屏的导体层间会形成一个耦合电容，触摸屏上电极产生的电流会流向触点，从而能够准确计算出触摸点的位置。
通常，触摸屏的导电膜是至关重要的部分，导电膜包括导电层和绝缘基材两部分，导电层主要是氧化铟锡(Indium Tin Oxide；简称：ITO)通过真空镀膜、图形化蚀刻的工艺形成于绝缘基材上，再将该导电膜通过胶粘层贴附在透明玻璃面板上，从而形成触摸屏。
现有触摸屏上导电层的结构如图1所示，包括第一图案电极1和第二图案电极2，其中第一图案电极1在X向上排列，第二图案电极2在Y向上排列，相交叉的部分形成为触控感应点。现有技术中，通常第一图案电极1和第二图案电极2均形成为如图1所示的菱形，结构比较单一，且存在容易受外界的杂讯干扰的问题。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开进行详细描述。
本公开具体实施例所述触控面板，包括导电层，所述导电层包括多个相互平行、沿Y向设置的第一电极层和多个相互平行、沿X向设置的第二电极层，其中所述第一电极层包括多个依次连接的第一图案电极，所述第二电极 层包括多个依次连接的第二图案电极，其中：
所述第一图案电极形成为六边形，相邻两列所述第一电极层之间的区域对应设置多个所述第二图案电极，且位于同一列、相邻两个所述第一图案电极之间具有第一连接端，位于同一行、相邻两个所述第二图案电极之间具有第二连接端，所述第一连接端和所述第二连接端在平行于所述导电层的平面上的投影至少部分重合。
本公开所述触控面板中，将第一图案电极的形状设计为六边形，第二图案电极位于相邻两列第一图案电极之间的区域，第二图案电极的形状与尺寸依据第一图案电极的形状与尺寸设计，相较于现有技术第一图案电极和第二图案电极均形成为菱形的结构形式，形成为一种新型的电极图形，且两列第一图案电极可以设计大面积的第二图案电极，构成大面的TX图形，能够有效屏蔽外界的杂讯。
本公开以下实施例中，统一将多个第二电极层的排列方向定义为X方向，将多个第一电极层的排列方向定义为Y方向，具体地该X方向和Y方向为十字交叉，但可能并非与通常方位的水平和竖直相对应。
另外，本领域技术人员可以理解，第一电极层和第二电极层可以位于一个平面内，也可以不位于一个平面内。当第一电极层和第二电极层可以位于一个平面内时，至少第一电极层和第二电极层的连接端之间还设置有电绝缘层，因此在相邻两个第一图案电极的第一连接端和相邻两个第二图案电极的第二连接端之间设置有电绝缘层。
图2为本公开第一实施例所述触控面板中导电层的平面结构示意图。图3为图2所示导电图案的局部结构示意图。
参阅图2和图3，在第一实施例中，触控面板的导电层包括沿Y向设置的第一电极层和沿X向设置的第二电极层，其中第一电极层包括多个依次连接的第一图案电极10，第二电极层包括多个依次连接的第二图案电极20，且第一图案电极10形成为六边形，第二图案电极20位于相邻的两列第一图案电极10之间。
具体地，第二图案电极20的边缘形状依据相邻接的第一图案电极10的边缘形状设置，这样，如图2所示第二图案电极20的图形与第一图案电极 10的图形如拼图形式，依据导电层的整个平面相组合。
此外，位于同一行、相邻两个第二图案电极20的第二连接端与位于同一列、相邻两个第一图案电极10的第一连接端在平行于导电层所在平面上的投影至少部分重合，该导电层所在平面同样为与第一图案电极10和第二图案电极20平行的平面。参阅图3所示，本公开实施例中，相邻两个第一图案电极10之间具有第一连接端，相邻两个第二图案电极20之间具有第二连接端，其中第一连接端处通过电极层直接连接，且在第一连接端处的X方向上具有宽度G；而在第二连接端处设置有搭桥，通过搭桥跨过相邻两个第一图案电极10的第一连接端使相邻的两个第二图案电极20连接。可以理解的是，在实际触控面板的构图中，第一图案电极10和第二图案电极20的连接形式并不仅限于该种方式，也可以形成为连接两个第二图案电极20的第二连接端通过电极层直接连接，连接两个第一图案电极10的第一连接端通过搭桥连接的结构。
另外，结合图2和图3，第一图案电极10形成为关于X向和Y向均对称的六边形形状，且包括两个相对且平行于Y向的边缘11；所述第二图案电极20的形状包括两个相对且平行于X向的边缘21。具体地，所述第一图案电极在Y方向上的尺寸为Py，在X方向上的尺寸为D，所述第二图案电极在X方向上的尺寸为Px，在Y方向上的尺寸为Py。参考图2和图3，以相邻两个第一图案电极10关于X向平行的两个中心线12和相邻两个第二图案电极20关于Y向平行的两个中心线22所划定的区域说明第一图案电极10和第二图案电极20的结构尺寸，可以理解的是，相邻两个第一图案电极10关于X向平行的两个中心线12之间的距离等于所述第一图案电极在Y方向上的尺寸，也即为Py，相邻两个第二图案电极20关于Y向平行的两个中心线22之间的距离等于所述第二图案电极在X方向上的尺寸，也即为Px。图3所示则为相邻两个所述第一图案电极10关于X向平行的中心线12之间以及相邻两个所述第二图案电极20关于Y向平行的中心线22之间区域所构成的图形，也即图2中区域A的图形。
本公开实施例中，位于相邻两行的两个所述第二图案电极20之间的间隙为E，该间隙E在图3中所反映的结构为：第一图案电极10关于X向平行的 中心线12与第二图案电极20关于X向平行的边缘21(参阅图2)之间具有间隙H，其中H的数值等于E/2。
较佳地，第一图案电极10与第二图案电极20的各对应边缘之间也均具有间隙E。
本公开实施例中，当所述第一图案电极10在Y方向上的尺寸为Py，所述第二图案电极20在X方向上的尺寸为Px时，也即参阅图3，位于同一列且相邻两个所述第一图案电极10关于X向平行的中心线之间的距离为Py，位于同一行且相邻两个所述第二图案电极20关于Y向平行的中心线之间的距离为Px时，对于第一图案电极10，在X方向上的尺寸为D，也即两个相对且平行于Y向的边缘11之间的距离为D；对于第二图案电极20，关于Y向平行的中心线与相邻近的关于Y向平行的边缘之间的距离为C时，较佳地，上述各数值的取值依据如下表1确定，其中Px与Py的值可以为相等也可以为不等。

本公开第一实施例所述触控面板的导电层中，利用以上的结构设计，相较于现有技术第一图案电极和第二图案电极均形成为菱形的结构形式，本公开形成为一种新型的电极图形，且根据图2，两列第一图案电极之间的第二图案电极相较于现有技术的菱形图形面积增大，构成大面的TX图形，能够有效屏蔽外界的杂讯。
此外，本公开还提供第二实施例的触控面板，在该第二实施例中，在相 邻接的第一图案电极与第二图案电极之间还设置有第三图案电极，且第三图案电极围绕第一图案电极的边缘设计，此外每一第一图案电极的中心部分还设置有第四图案电极。
利用相分隔设置于第一图案电极与第二图案电极之间的第三图案电极和第四图案电极，产生互电容，达到调节第一图案电极与第二图案电极之间的电容的效果，本公开第二实施例中，较佳地，通过增加的第三图案电极和第四图案电极，将整个导电层的电容值调节至0.8至3PF之间，以能够兼容触控面板所连接驱动芯片的电容值，并搭配不同厂家的驱动芯片。此外，较佳地，本实施例的触控面板的电容值设计在1.1至1.6PF之间的触控效果最佳。
如图4为本公开第二实施例中所述导电层的平面结构示意图。图5为图4所示导电图的局部放大结构示意图。在第一实施例的基础上，本公开第二实施例所述触控面板的导电层中，第一图案电极10与第二图案电极20之间增加了第三图案电极30，第一图案电极10的内部增加了第四图案电极40。
结合图4与图5，第一图案电极10和第二图案电极20的形状与第一实施例中相同。具体地，第一图案电极10形成为六边形，第二图案电极20位于相邻的两列第一图案电极10之间，第二图案电极20的边缘形状依据相邻接的第一图案电极10的边缘形状设置。
此外，位于同一行、相邻两个第二图案电极20的第二连接端与位于同一列、相邻两个第一图案电极10的第一连接端在平行于导电层的平面上的投影至少部分相重合。参阅图3所示，本公开实施例中，相邻两个第一图案电极10具有第一连接端，通过电极层直接连接，且第一连接端在X方向具有宽度G；而相邻两个第二图案电极20具有第二连接端，设置有搭桥，通过搭桥跨过相邻两个第一图案电极10的第一连接端使相邻的两个第二图案电极20连接。
另外，结合图4和图5，第一图案电极10形成为关于X向和Y向均对称的六边形形状，且包括两个相对且平行于Y向的边缘11；所述第二图案电极20的形状包括两个相对且平行于X向的边缘21。
所述第一图案电极在Y方向上的尺寸为Py，在X方向上的尺寸为D，所述第二图案电极在X方向上的尺寸为Px，在Y方向上的尺寸为Py。参考 图2和图3，以相邻两个第一图案电极10关于X向平行的两个中心线12和相邻两个第二图案电极20关于Y向平行的两个中心线22所划定的区域说明第一图案电极10和第二图案电极20的结构尺寸，可以理解的是，相邻两个第一图案电极10关于X向平行的两个中心线12之间的距离等于所述第一图案电极在Y方向上的尺寸，也即为Py，相邻两个第二图案电极20关于Y向平行的两个中心线22之间的距离等于所述第二图案电极在X方向上的尺寸，也即为Px。
图5所示则为相邻两个所述第一图案电极10关于X向平行的中心线12之间以及相邻两个所述第二图案电极20关于Y向平行的中心线22之间区域所构成的图形，也即图4中区域B的图形。
本公开实施例中，位于相邻两行的两个所述第二图案电极20之间的间隙为E，该间隙E在图5中所反映的结构为：第一图案电极10关于X向平行的中心线12与第二图案电极20关于X向平行的边缘21(参阅图2)之间具有间隙H，其中H的数值等于E/2。
在上述结构的基础上，沿第一图案电极10和第二图案电极20的边缘之间设置有第三图案电极30，本公开实施例中，第一图案电极10形成为六边形，第三图案电极30可以形成为沿第一图案电极10的每一边缘设置的结构，也可以形成为只沿第一图案电极10的一个边缘或者几个边缘设置的结构，另外第三图案电极30沿第一图案电极10的边缘设置的各部分之间可以为连接，也可以为断开(如图5所示)，具体依据需要调节电容量的多少确定。
另外，为保证第一图案电极10和第二图案电极20在连接端处的触摸感应敏感度，设置于第一图案电极10的第一连接端处两侧的第三图案电极30，靠近第一连接端的顶面应该与第一连接端具有预定距离，如图5所示的，距离I。
进一步，本公开第二实施例中，第四图案电极40的形状与第一图案电极10的形状相同，且设置于第一图案电极10的中心处。
且较佳地，参阅图5，第三图案电极30与第一图案电极10之间、第三图案电极30与第二图案电极20之间、第四图案电极40与第一图案电极10之间具有间隙E；第三图案电极30的宽度为A，第一图案电极10的宽度为B， 根据图4，第一图案电极10形成为六边形的环状结构，本实施例中所述第一图案电极10的宽度是指环状结构的内环边缘至外环边缘的垂直距离；另外第一图案电极10的两个相对且平行于Y向的边缘11之间的距离为D。
较佳地，上述各数值的取值依据如下表2确定：

采用上述的尺寸设计时，能够将触控面板的电容值设计在0.8至3PF之间，以能够兼容触控面板所连接驱动芯片的电容值(通常驱动芯片的电容值在1至3PF之间)，并搭配不同厂家的驱动芯片。以下表格3中给出了各结构尺寸采用上述范围的其中一数值时所获得电容值，实验证明，当各结构尺寸采用上述范围限定的数值时，能够将触控面板的电容值设计在0.8至3PF之间，以兼容触控面板所连接驱动芯片的电容值，具体地Px、Py、A、B、D、G、H、I、E的单位为mm。

本公开具体实施例的另一方面，为避免应用于显示器时，上述结构中的横向和竖向的电极形成干涉条纹，较佳地，将第一图案电极、第二图案电极、第三图案电极和/或第四图案电极的边缘制成为波纹形状，如图6所示，波纹 的宽度L在0.1mm至0.3mm之间，角度α为120至160度。
