具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
本发明提供了一种用于触控面板的搭桥结构，图5是所述搭桥结构的平面示意图。所述搭桥结构包括金属桥1和设置在金属桥1上的绝缘块3，金属桥1具有超出绝缘块3的两个端部10，两个端部10分别用于与两个待连接的电极块电相连(图中标号a处所示)，所述搭桥结构还包括至少一个支撑部31，支撑部31的至少一部分位 于所述端部10的外侧，且支撑部31填充所述电极块与所述端部10之间的缝隙。
如上所述，通常触控面板包括设置在绝缘块3所在层上方的沿不同方向延伸的第一电极21和第二电极22。其中，第一电极21和第二电极22之间相互绝缘。第一电极21包括多个第一电极块210，在第一电极21的延伸方向上相邻的两个第一电极块210通过金属桥1电连接。在图5中，金属桥1的两个端部10分别与纵向相邻的两个第一电极块210电连接。
图6是示出一个第一电极块210与金属桥1的一个端部10连接的剖面示意图。由于支撑部31的至少一部分位于端部10的外侧，因此，当第一电极块210形成在绝缘块3所在层的上方时，支撑部31可以位于第一电极块210与金属桥1的端部10的交界处，将第一电极块210紧靠金属桥1的端部10的外侧的部分垫高(如图6所示)(即，由于第一电极块210与金属桥1的端部10在其交界处的高度差而产生的缝隙被填充)，从而调整了第一电极块210与金属桥1的端部10的连接处的形状，改善了第一电极块210的爬坡路径，使第一电极块210在金属桥1的端部10上方与金属桥1更好地搭接，有效避免了由于第一电极块210与金属桥1的端部10之间的高度差导致的断裂等问题，使所述搭桥结构的电连接更加稳定可靠，改善了触控面板的抗静电能力。
在本发明中，支撑部31可以全部位于金属桥1的端部10的外侧，如图6中所示；可替代地，支撑部31也可一部分位于金属桥1的端部10的外侧，另一部分位于金属桥1的端部10上，如图7中所示，本发明对此不作限制，只要支撑部31可以填充由于电极块210与金属桥1的端部10之间的高度差而产生的缝隙，使得第一电极块210的爬坡路径得到改善，从而避免第一电极块210发生断裂或者塌陷即可。
此外，支撑部31的最高点优选高于金属桥1的端部10，如图6和图7中所示。这是由于，当支撑部31的最高点高于金属桥1的端部10时，可以进一步确保由于第一电极块210与金属桥1的端部10 之间的高度差而产生的缝隙被填充，能够在最大程度上避免第一电极块210可能发生的断裂问题。
优选地，支撑部31的顶面设置为外凸的曲面(例如，弧面或球面)，相应地，第一电极块210通过所述曲面与金属桥1的端部10进行电连接，使得第一电极块210的爬坡路径得到改善，从而使本发明中的搭桥结构更加稳固。
在本发明中，支撑部31可以由任何的透明绝缘材料制成，例如，支撑部31可以由树脂材料制成。
进一步地，支撑部31可以与绝缘块3形成为一体，即两者同步形成。例如，可以采用半色调掩膜板，通过调整半色调掩膜板不同位置的透光率，同步曝光形成平板状的绝缘块3和顶面为外凸的曲面的支撑部31，这样无需增加多余的工艺步骤，即可实现本发明。
本发明还提供了一种触控面板。如上所述，以图5为例，所述触控面板包括沿第一方向延伸的第一电极21和沿第二方向延伸的第二电极22，并且第一电极21和第二电极22之间相互交错且绝缘。其中，第一电极21包括多个第一电极块210和多个搭桥结构，在第一方向相邻的两个第一电极块210通过搭桥结构电连接。其中，多个所述搭桥结构中的至少一个为本发明所提供的上述搭桥结构，第一电极块210形成在所述搭桥结构的绝缘块3所在层的上方，搭桥结构的金属桥1的两个端部10分别与在第一方向相邻的两个第一电极块210电连接。
本发明所提供的触控面板中，由于在第一电极块210与金属桥1的端部10交界的位置设置了支撑部31，使得第一电极块210被垫高，有效避免了由于第一电极块210与金属桥1的端部10之间的高度差导致的断裂等问题，从而避免了电连接失效或不良等问题，改善了触控面板的抗静电能力。
具体地，如图6中所示，第一电极块210包括位于支撑部31上的第一部分210a和位于金属桥1的端部10上的第二部分210b。由于支撑部31的最高点优选高于金属桥1的端部10，因此第一部分210a的最高点也高于第二部分210b，确保了第一电极块210与金属 桥1的端部10可以很好地搭接，能够在最大程度上避免第一电极块210可能发生的断裂问题。
当支撑部31的顶面为外凸的曲面时，第一电极块210中的第一部分210a为曲面部，第二部分210b为平面部，所述曲面部的最高点优选高于所述平面部，以使得第一电极块210的爬坡路径得到改善，并且使得所述搭桥结构更加稳固。
综上所述，本发明所提供的触控面板具有更好的电连接性能，同时增强了搭桥结构的稳固性，有效改善了触控面板的抗静电能力。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
