需要说明的是，当元件被称为“固设于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1，一实施方式的触摸屏10包括面板100及设于该面板100的其中一表面上的一触摸感应元件200。
面板100为透明板，例如，该面板100可以为玻璃板或透明塑料板。
该触摸感应元件200包括一透明的绝缘基材210、形成于该绝缘基材210一表面的导电层230。具体在图示的实施例中，该触摸感应元件200通过一光学透明胶层220贴合于该面板100上。
绝缘基材210为片状，材料为聚对苯二甲酸类塑料（PET）、聚碳酸酯（PC）或玻璃。绝缘基材210具有第一表面及与第一表面相对的第二表面。该导电层230位于该基材的第一表面。具体在图示的实施例中，该导电层230通过一基质层240附着于该绝缘基材210的第一表面。该基质层240为透明绝缘材料，例如，该基质层240为无溶剂紫外固化亚克力树脂。该基质层240上设有若干凹槽241，导电层230形成于所述凹槽241中。凹槽241的深度不小于所导电层230的厚度。在实际生产中，该基质层240同时可用于导电层230的成型。
请参阅图2，该导电层230包括相互间隔的若干第一导电线迹231及若干第二导电线迹233。具体在图示的实施例中，第一导电线迹231及第二导电线迹233由若干导电线呈网格状排列形成。网格呈菱形。该导电线位于该基质层240的凹槽241中。导电线的材料可以选自金、银、铜、铝、锌或其合金。
若干第一导电线迹231沿二维座标系的第一维方向排列，每一第一导电线迹231沿二维座标系的第二维方向延伸。每一第一导电线迹231包括一第一主线231a及自该第一主线231a向侧向延伸的若干第一侧枝231b。第一主线231a二维座标系的第二维方向延伸且相互平行，第一侧枝231b沿二维座标系的第一维方向延伸且相互平行。
第二导电线迹233排列成若干第二导电线迹列，每一第二导电线迹列包括若干沿二维座标系的第二维方向间隔排列的第二导电线迹233。第二导电线迹列对应位于一第一导电线迹231的侧向，每一,第二导电线迹列中的每一第二导电线迹233间隔排列，以与第一导电线迹231形成互感。每一第二导电线迹233包括一第二主线233a及自该第二主线233a向侧向延伸的若干第二侧枝233b。第二主线233a沿二维座标系的第二维方向延伸，第二主线233a的末端相互间隔。
具体在图示的实施方式中，二维坐标系为XOY直角坐标系，第一维方向为X轴，第二维方向为Y轴。当然，在发明中，二维坐标系也为其他坐标系，例如，二维斜角坐标系。
请同时参照图3，第二侧枝233b沿二维座标系的第一维方向延伸且相互平行，每一第二主线233a与对应的一第一主线231a相互平行。第一侧枝231b与第二侧枝233b位于对应的第一主线231a与第二主线233a之间，且间隔交叉排列，以与该第一导电线迹231形成互感。
导电层230进一步包括若干第一导电引线235及若干第二导电引线237，每一第一导电引线235电连接于一第一导电线迹231的端部，以将该第一导电线迹231与外部处理芯片或电路连接。每一第二导电线迹233连接于一第二导电线迹233的端部，以将该第一导电线迹231与外部处理芯片或电路连接。
第一导电引线235及第二导电引线237同样可以由若干导电线呈网格状排列形成。网格可以呈菱形。导电线的材料选自金、银、铜、铝、锌、镍或其的合金。
上述触摸屏10在工作时，导电层230的第一导电线迹231可以实施现触摸位置在二维座标系的第一维方向上的定位，导电层230的第二导电线迹233可以实现触摸位置在二维座标系的第二维方向上的定位，且第二导电线迹233在二维座标系的第一维方向及第二维方向上相互间隔，从而可以实现直正的多点触摸操作，无鬼点出现。另外，上述触摸屏10的导电层230形成于该绝缘基材210的一个表面上，相对于通过在绝缘基材210的两个表面上形成导电层230以实现触控操作的触摸屏10来说，上述触摸感应元件200结构及制程均更加简单。
需要说明的是，在上述实施例中，导电层230的第一导电线迹231、第二导电线迹233、第一导电引线235及第二导电引线237均由若干导电线呈网格状排列组成，然而，在其它的实施例中，第一导电线迹231、第二导电线迹233、第一导电引线235及第二导电引线237还可以由其他导电材料形成，如氧化铟锡（ITO）、高分子导电材料、石墨烯、碳纳米管等。
请参阅图4，图4示出了另一实施方式中的触摸感应元件400，其与前一实施方式中的触摸感应元件400基本相同，其不同之处在于：图4所示的实施方式中的触摸感应元件400的导电层430进一步包括若干配色线迹439。
请同时参照图5，配色线迹439分布于第一导电线迹431及第二导电线迹433之间且与第一导电线迹431、第二导电线迹433、第一导电引线435及第二导电引线437绝缘。配色线迹439的形状与第一导电线迹431、第二导电线迹433、第一导电引线435及第二导电引线437所形成的图案形状互补。
请参照图6，配色线迹439分布于第一导电线迹431、第二导电线迹433、第一导电引线435及第二导电引线437之间。配色线迹439由导电线形成，形成配色迹的导电线排列成网格状、锯齿状或折线状，并且形成配色线迹439的导电线与构成第一导电线迹431、第二导电线迹433、第一导电引线435及第二导电引线437的导电线断开，且每一网格单元的中部断开，导电线被截断处形成缺口439a，缺口439a沿二维座标系的第一维方向及第二维方向均呈直线排列。导电线的线径与组成第一导电线迹431、第二导电线迹433、第一导电引线435及第二导电引线437的导电线的线径相同。
配色线迹439可以使触摸感应元件400上的光线看起来更均匀，以提高使用者的舒适度。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
