如图2所示，本实施例提供的触控结构包括多个触控电极2和遮光层3。其中，触控电极2可以通过金属线构成，多条金属线围成多个重复的网格单元，每一网格单元即为一个触控电极2，其中每个网格单元可以呈菱形，即每个触控电极2可以呈菱形。多个触控电极2设于同一层，以构成触控层，且相邻的触控电极2之间具有电极间隙4，以防止触控电极2之间相互短路。遮光层3设于多个触控电极2的一侧，即遮光层3设于触控层的一侧，遮光层3与电极间隙4的位置相对应，即遮光层3对应设置在电极间隙4 的上方，即遮光层3在触控层上的正投影位于电极间隙4内。
在具体实施时，先制作出多个触控电极2，在多个触控电极2的一侧涂布一层遮光材料，进而对涂布的遮光材料进行曝光显影，以在电极间隙4的上方形成遮光图案，该遮光图案即构成遮光层3。其中，遮光层3所采用的遮光材料可以为黑矩阵光刻胶。
本实施例在电极间隙4的上方设置遮光层3，以在触控结构应用在显示面板时，避免触控电极2之间的电极间隙4过大引起显示面板显示亮度不均的问题，从而提高显示面板的显示均匀性。
进一步地，如图3所示，所述触控结构还包括保护层5，保护层5设于触控层与遮光层3之间。具体地，保护层5设于多个触控电极2上，遮光层3设于保护层5上。其中，保护层5的材料可以为有机材料，保护层5用于对多个触控电极2进行保护。
进一步地，如图2所示，所述多个触控电极2包括多个第一触控电极21和多个第二触控电极22；所述第一触控电极21和所述第二触控电极22相互绝缘且交叉设置，形成互容式电极结构。
需要说明的是，第一触控电极21可以为触控感应电极（RX），第二触控电极22可以为触控驱动电极（TX）。第一触控电极21与第二触控电极22整体为十字交叉设置，且第一触控电极21与第二触控电极22在交叉处电性绝缘，使得第一触控电极21与第二触控电极22相互绝缘。
具体地，所述多个第一触控电极21沿第一方向延伸设置为多列，且每列相邻的第一触控电极21电性连接；所述多个第二触控电极22沿第二方向延伸设置为多行，且每行相邻的第二触控电极22电性连接。

具体地，如图3所示，所述第一触控电极21和所述第二触控电极22的交叉处设有金属线6，每列相邻的第一触控电极21通过所述金属线6电性连接。
需要说明的是，金属线6属于触控层，即金属线6与第一触控电极21、第二触控电极22同层设置，每列相邻的两个第一触控电极21之间均设有一金属线6，且金属线6的两端分别与其相邻的两个第一触控电极21连接，从而实现每列相邻的两个第一触控电极21的电性连接。保护层5还设置在金属线6上，用于对金属线6进行保护。
具体地，如图3所示，触控层远离遮光层3的一侧设有架桥7，即所述多个触控电极2远离所述遮光层3的一侧设有架桥7，且所述架桥7与所述第一触控电极21和所述第二触控电极22的交叉位置相对应；每行相邻的第二触控电极22通过所述架桥7电性连接。
需要说明的是，架桥7与触控层位于不同层，即架桥7与第一触控电极21、第二触控电极22、金属线6不同层设置。架桥7可以位于触控层的下方，且每行相邻的两个第二触控电极22之间均对应有一架桥7。每行相邻的两个第二触控电极22可朝向其对应的架桥7延伸，以分别与架桥7的两端连接，从而实现每行相邻的两个第二触控电极22的电性连接。
本实施例中每列相邻的两个第一触控电极21在触控层中电性连接，而每行相邻的两个第二触控电极22在触控层中断开，并通过与触控层不同层的架桥7实现电连接，避免第一触控电极21与第二触控电极22短路，有效保证第一触控电极21和第二触控电极22的相互绝缘。
进一步地，如图3所示，所述金属线6与所述架桥7之间设有绝缘层8，且所述绝缘层8中设有通孔81，每行相邻的第二触控电极22通过所述通孔81与所述架桥7电性连接。
需要说明的是，绝缘层8用于对金属线6和架桥7进行绝缘。绝缘层8可以设置在触控层与架桥7之间，具体地，绝缘层8设于架桥7上，第一触控电极21、第二触控电极22、金属线6设于绝缘层8上，保护层设于第一触控电极21、第二触控电极22、金属线6和绝缘层8上。
每行相邻的两个第二触控电极22所对应的绝缘层8中两个通孔81，且两个通孔81与对应的架桥7两端的位置相对应。每行相邻的两个触控电极22可分别延伸至其对应的通孔，与其对应的架桥7连接，从而实现每行相邻的两个第二触控电极22的电性连接。
进一步地，所述触控结构还包括缓冲层9；所述架桥7设于所述缓冲层9上，所述绝缘层8还设于所述缓冲层9上。
在具体实施时，先形成缓冲层9，在缓冲层9上形成架桥7，在缓冲层9和架桥7上形成绝缘层8，在绝缘层8上形成第一触控电极21、第二触控电极22和金属线6，进而在第一触控电极21、第二触控电极22、金属线6和绝缘层8上形成保护层5，最后在保护层5上形成遮光层3。
由上述可知，本实施例提供的触控结构，能够多个触控电极之间具有电极间隙，在电极间隙的上方设置遮光层，避免电极间隙过大引起显示面板显示亮度不均的问题，从而提高显示面板的显示均匀性，提高显示效果。
参见图4，是本发明实施例提供的显示面板的结构示意图。
如图4所示，所述显示面板包括基板31、发光层32和触控结构33。其中，柔性基板31的材料可以为聚酰亚胺PI，触控结构33为上述实施例中的触控结构，在此不再详细赘述。发光层32设于柔性基板31的一侧，触控结构33设于发光层32远离柔性基板31的一侧。
其中，发光层32包括多个间隔设置的子像素，多个间隔设置的子像素呈阵列排布，且相邻子像素之间具有像素间隙，触控结构33中的多个触控电极2的金属线与像素间隙对应设置，即多个触控电极2在发光层32上的正投影位于像素间隙中，从而不影响子像素的正常显示。
进一步地，如图4所示，显示面板还包括薄膜封装层34、偏光片35和柔性盖板36。其中，薄膜封装层34设于发光层32和触控结构33之间，偏光片35设于触控结构33远离柔性基板31的一侧，柔性盖板36设于偏光片35远离柔性基板31的一侧。薄膜封装层34用于对发光层32进行封装。
由上述可知，本实施例提供的显示面板，能够多个触控电极之间具有电极间隙，在电极间隙的上方设置遮光层，避免电极间隙过大引起显示面板显示亮度不均的问题，从而提高显示面板的显示均匀性，提高显示效果。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
