Description

一种触控电极结构及触控面板 技术领域
本发明涉及液晶显示领域，具体涉及一种触控电极结构及触控面板。
 背景技术
随着显示科技的进步，目前触控技术已经广泛应用于各显示面板。通常，为实现显示面板的触控功能，一种方案是将触摸面板与显示面板单独制作，然后将触摸面板贴合在显示面板的上表面形成完整的触控面板，但这种结构会增加触控面板的厚度，且需要额外的贴合工艺；另一种方案则是通过在显示面板的薄膜封装层上制作触控电极结构，从而实现显示面板的触控功能。
然而，通过在显示面板的薄膜封装层上制作触控电极结构的触控面板，为了实现部分电极之间的电性连接，通常是通过构建导电桥的方式实现；由于，这些导电桥通常为小面积的条状结构，因此导电桥两端与电极的接触面积同样较小，容易造成该接触处的连接阻抗偏高或者开路，进而降低触摸的灵敏度，增加延迟，并降低信噪比。

请参阅图1、图2，图1为本发明实施例提供的触控电极结构的平面性示意图；图2为图1所示的触控电极结构沿剖面线A-B截取的剖视图。本发明实施例的触控电极结构包括基板10以及多个触控单元11，触控单元11设置在基板10上。
需要说明的是，本发明实施例中的基板10，指的是用于承载该触控电极结构的基体构件。例如，以主动矩阵有机发光二极体面板为例，该主动矩阵有机发光二极体面板包括：层叠设置的基底、薄膜晶体管层、像素定义层、封装层以及触控电极结构，其中，设置在触控电极结构下面的基底、薄膜晶体管层、像素定义层和封装层，即为本发明实施例所提及的基板10。
结合图1、图2所示，每个触控单元11均包括：电极层20、导连接层40和绝缘层30。其中，电极层20包括第一图案化电极201和第二图案化电极202，且第二图案化电极202被第一图案化电极201分割成第一部分212和第二部分222；导电连接层40用于电性连接第一部分212和第二部分222，并与该电极层20在空间上隔离；绝缘层30位于电极层20和导电连接层40之间，且在绝缘层30上对应第一部分212和第二部分222上设有多个通孔301，以使该导电连接层40、第一部分212和第二部分222通过通孔301电性连接。

步骤S503，在所述电极层上形成一绝缘层，并在所述绝缘层上对应所述第一部分和第二部分上形成多个通孔；
步骤504,在所述绝缘层上形成导电连接层，并对所述导电连接层进行图案化处理，以形成网格结构的多条连接线，使所述导电连接层、第一部分和第二部分通过所述通孔电性连接。
本发明实施例提供的触控电极结构的制作方法中，各步骤均可参照以上所述的触控电极结构的描述，在此不做赘述。
本发明所述提供的触控电极结构及触控面板，通过设置一绝缘层置于电极层和导电连接层之间，且在绝缘层上对应第一部分和第二部分上设置多个通孔，以使导电连接层、第一部分和第二部分通过通孔电性连接，从而降低连接阻抗，进而提高触控灵敏度，减小RC延迟，提高信噪比。
请参阅图4、图5，图4为本发明另一实施例提供的触控电极结构的平面性示意图；图5为图4所示的触控电极结构沿剖面线A-B截取的剖视图。本发明实施例的触控电极结构包括基板60以及多个触控单元61，触控单元61设置在基板60上。
需要说明的是，本发明实施例中的基板60，指的是用于承载该触控电极结构的基体构件。例如，以主动矩阵有机发光二极体面板为例，该主动矩阵有机发光二极体面板包括：层叠设置的基底、薄膜晶体管层、像素定义层、封装层以及触控电极结构，其中，设置在触控电极结构下面的基底、薄膜晶体管层、像素定义层和封装层，即为本发明实施例所提及的基板60。
结合图4、图5所示，每个触控单元61均包括：电极层70、导连接层90和绝缘层80。其中，电极层70包括第一图案化电极701和第二图案化电极702，且第二图案化电极702被第一图案化电极201分割成第一部分712和第二部分722；导电连接层90用于电性连接第一部分712和第二部分722，并与该电极层70在空间上隔离；绝缘层80位于电极层70和导电连接层90之间，且在绝缘层80上对应第一部分212和第二部分222上设有多个通孔801，以使该导电连接层90、第一部分712和第二部分722通过通孔801电性连接。
进一步的，如图4所示，该导电连接层90为网格结构，其中，该网格结构包括多条交错且电性连接的连接线，连接线通过多个通孔801将第一部分712和第二部分722电性连接。具体的，该连接线包括：多条第一连接线901、多条第二连接线902、多条第三连接线903和多条第四连接线904，多条第一连接线901和多条第二连接线902一一交错且电性连接，多条第三连接线903和多条第四连接线904一一交错且电性连接，即，通过多条第一连接线901、多条第二连接线902、多条第三连接线903和多条第四连接线94形成一网格。以主动矩阵有机发光二极体面板为例，本发明实施例通过在每个触控单元61的导电连接层上形成一网格，从而使得多个触控单元61中形成网格结构的导电连接层90，进而可以避开像素发光区域，不影响以主动矩阵有机发光二极体面板的发光显示效果。
其中，在绝缘层80上对应第一部分712的通孔801与对应第二部分722的通孔一一对应。也就是说，位于绝缘层80上对应第一部分712的通孔801的形状、数量、排布等均与位于绝缘层80上对应第二部分722的通孔801一致。特别的，导电连接层90上的连接线均通过通孔801与第一部分712和第二部分722电性连接。
结合图4、图5所示，本发明实施例中，导电连接层90、绝缘层80、电极层70依次层叠设置在基板60上。另外，在本发明实施例中，电极层70的材质为透明导电薄膜；导电连接层90的材质为金属。
进一步的，请参阅图6，图6为本发明另一实施例供的触控电极结构的制作流程示意图。如图6所示，本发明实施例提供的触控电极结构的制作方法，包括以下步骤：
步骤S1001，提供一基板；

步骤1004,在所述绝缘层上形成形成一电极层，并对所述电极层进行图案化处理，以形成第一图案化电极和第二图案化电极，且所述第二图案化电极被所述第一图案化电极分割成第一部分和第二部分，所述第一部分、第二部分和连接线通过所述通孔电性连接。
本发明实施例提供的触控电极结构的制作方法中，各步骤均可参照以上所述的触控电极结构的描述，在此不做赘述。
本发明所述提供的触控电极结构及触控面板，通过设置一绝缘层置于电极层和导电连接层之间，且在绝缘层上对应第一部分和第二部分上设置多个通孔，以使导电连接层、第一部分和第二部分通过通孔电性连接，从而降低连接阻抗，进而提高触控灵敏度，减小RC延迟，提高信噪比。
