 本发明的实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
请参阅图2，图2为本申请实施例提供的触控显示面板的结构示意图。
本申请实施例提供一种触控显示面板，包括：
基板10，以及设置在基板10上的多个电极20。
驱动芯片30，电极20通过走线40连接至驱动芯片30。其中，至少部分走线40与电极20处于不同层。
例如，基板10是玻璃基板、高导热铝基板或者是形成有聚酰亚胺（Polyimide，PI）的基板，也可以是薄膜晶体管（Thin Film Transistor，TFT）基板或者是有机发光二极管（Organic Light Emitting Diode，OLED）基板。多个电极20包括多个驱动电极以及多个感应电极。其中，该多个电极20均通过走线40连接至驱动芯片30上。并且，至少部分走线40与电极20处于不同层。
另外，在一些实施例中，部分走线40在基板10上的投影与电极在基板上的投影重合。
请继续参阅图2，多个电极20包括多个第一电极201和多个第二电极202。多个第一电极201在第一方向上电连接形成第一电极链210。多个第二电极在第二方向上电连接形成第二电极链220，走线40包括第一走线401和第二走线402。
第一电极链210与第二电极链220交叉设置。其中，第一电极链210通过第一走线401连接至驱动芯片30以及，第二电极链220通过第二走线402连接至驱动芯片30，且第一走线401与第一电极201位于不同层。
该第一电极201可以是感应电极，也可以是驱动电极。该第二电极202可以是感应电极，也可以是驱动电极。具体根据实际情况进行设定。多个第一电极201沿第一方向排布，并在第一方向上形成第一电极链210。多个第二电极202沿第二方向排布，并在第二方向上形成第二电极链220。其中，该第一电极链210与第二电极链220交叉设置，也即，第一方向与第二方向交叉。比如，在第一方向上，设置有M行第一电极201，在第二方向上，设置有N列第二电极202，其中M和N均为大于或等于1的正整数，如图2所示。在本申请实施例中，第一方向指的是第一电极201的布置方向，第二方向指的是第二电极202的布置方向，图2中第一电极201和第二电极202的位置仅仅只是示意，而不是对本申请的限制。
另外，在本申请实施例中，第一走线401与第一电极201位于不同层。例如，由第一电极201的内部引出第一走线401连接至驱动芯片30，其中，第一走线201沿第二方向延伸并沿第一方向排列。第二走线402由第二电极202的内部引出，且第二电极202通过第二走线402连接至驱动芯片30。
在本申请实施例中，将第一走线401与第一电极201设置在不同层，达到了在增大布线区域的同时不增加边框区域的目的，从而解决了触控显示面板的边框区域较大的技术问题。
在一些实施例中，与第二走线402相连接的第二电极202在基板10上的投影与第一走线401在基板10上的投影重合。
在一些实施例中，请参阅图3以及图4。第一电极201与第一走线401通过设置在第一电极201上的连接孔50连接。即，第一电极201上设置有一连接孔50，第一走线401通过连接孔50与第一电极201相连接。其中，根据连接孔50与驱动芯片30之间的距离，按照由远至近的顺序沿第二方向依次排布所述第一走线101。
比如，第一电极201设置有一连接孔50，第一走线401从连接孔50的位置引出。并且，第一电极201通过第一走线401与驱动芯片30相连接。在第二方向上，第M行第一电极201上的连接孔与第M-1行第一电极201上的连接孔不在同一直线上，第M-1行第一电极201上的连接孔与第M-2行第一电极201上的连接孔不在同一直线上，以此类推，这样便于第一走线201的布线，在此不再赘述。
请参阅图3~图5，在本申请的一些实施例中，该触控显示面板还包括：
多个导电桥203，导电桥203沿第二方向排列，且导电桥203与第二电极202位于不同层，导电桥203与第一走线401位于同一层。其中，相邻两个第二电极201通过一个导电桥203连接。
比如，相邻两个第二电极201通过一个导电桥203进行电性连接，使得位于同一列的第二电极202的信号可以通过第二走线402传输至驱动芯片30。需要说明的是，该导电桥203为跨线结构，该跨线结构使得相邻两个第二电极202之间的连接可以避开第一电极201。
在一些实施例中，第一走线401、第二走线201以及导电桥203均位于同一层。其中，第二走线402沿所述第一方向延伸并沿第二方向排列。
其中，由于第一方向与第二方向交叉，所以第一走线401与第二走线402至少部分交叉。并且，第一走线401与第二走线402至少部分垂直。在本实施例中，第一走线401与第二走线402至少部分交叉指的是第一走线401与第二走线402在基板10的投影上至少部分交叉，而并不是指第一走线401与第二走线402相交。也就是说，第一走线401与第二走线402垂直也指的是第一走线401与第二走线402在基板10的投影上至少部分垂直。
在一些实施例中，第一走线401与第二走线402位于不同层。其中，第二走线401沿第一方向延伸并沿第二方向排列。
其中，第一走线401与导电桥203位于同一层，具体请参见前面实施例。在本实施例中，第一走线401与第二走线402位于不同层，也就是说第二走线402与第一电极201以及第二电极202位于同一层。在另一种实施方式中，第二走线401和第一电极201、第二电极202以及第一走线401位于不同层。而第二走线401的设置方法与前面实施例的相同，在此不再赘述。
另外，第二走线402的设置可以结合前面两个实施例的方法进行设置，即一部分第二走线402、第一走线401以及导电桥203位于同一层。另一部分第二走线402、第一走线401以及导电桥203位于不同层，这样不仅便于第二走线402的布线，同时还可以增大第一走线401与第二走线402之间的间隙，减小第一走线401与第二走线402互相干扰的几率。具体的设置方法请参见前面实施例，在此不再赘述。
请参阅图6，相邻第一电极201与导电桥203之间还设置有一绝缘层601，以使相邻第一电极201与导电桥203相互绝缘。
以第一电极201为感应电极，第二电极202为驱动电极为例进行说明。具体的，第二电极202用于接收触控驱动信号，第一电极201用于产生触控感应信号。在第一电极201和第二电极202邻近的地方可以形成耦合电容，当人体接触到显示面板时，由于人体接地，手指与显示屏之间就会形成一个与上述耦合电容串联的电容，进而会造成第一电极201所检测到的电容减小并可产生相应的触控感应信号，由此再经过相应的转换就可以确定具体的触控发生位置。因此，为了使第一电极201和导电桥203绝缘。所以在相邻第一电极202与导电桥203之间设置一绝缘层601，以使第一电极201与导电桥203相互绝缘。在一些实施方式中，还可以在第一电极201和第二电极202上设置一保护层602，用以保护第一电极201和第二电极202，使得第一电极201以及第二电极202与位于其上的膜层绝缘。
在一些实施例中，第一电极201、第二电极202以及导电桥203均为网格状结构。
比如，可以将第一电极201、第二电极202以及导电桥203设置为网格状金属走线，一方面，可以减小第一电极201和第二电极202的阻抗，提高触控显示面板的触控灵敏度.另一方面，网格状金属走线的延展性好，还可以进一步提高触控显示面板的弯折能力。
在一些实施例中，网格状导电桥203至少部分与网格状第二电极202重合。
在一些实施例中，第一走线201与所述第二走线202的材料为透明氧化物。
在一些实施例中，第一走线101与第二走线201的材料相同，均为铟锡氧化物，以避免降低触控显示面板的开口率。
相应的，本申请还提供了一种显示装置，包括本申请任一实施例的触控显示面板。
在本实施例中，通过将第一走线401沿第二方向延伸并沿第一方向排列设置，且将第一走线401与第一电极201设置在不同层，达到了增大布线区域的同时不增加边框区域的目的，解决了触控显示面板的边框区域较大的技术问题。
以上对本申请实施例提供的触控显示面板以及显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
