请参照附图中的图式，其中相同的组件符号代表相同的组件。以下的说明是基于所例示的本申请具体实施例，其不应被视为限制本申请未在此详述的其它具体实施例。
请参照图2，图2为本申请的触控面板的第一实施例的结构示意图。
本第一实施例的触控面板划分为显示触控区D1和设置在显示触控区D1一侧的非显示触控区D2，触控面板包括显示触控芯片11、触控连接线12、接地连接线。
显示触控芯片11设置在非显示触控区D2，用于实现面板的显示和触控功能，其包括用于连接显示触控区D1的以实现触控功能的第一触控引脚111和空余的第二触控引脚112；触控连接线12设置在显示触控芯片11和显示触控区D1之间，连接显示触控区D1和第一触控引脚111；
接地连接线设置在非显示触控区D2，连接显示触控区D1的地相和第二触控引脚112。
本第一实施例将空余的第二触控引脚112通过接地连接线连接于触控面板的地相，当有干扰信号或静电窜入第二触控引脚112时，干扰信号和静电会经接地连接线导走，避免了显示触控芯片11内部信号的相互干扰和避免了显示触控芯片11内部电路被静电击伤。
在本第一实施例中，接地连接线包括连接于第二触控引脚112的接地支线131和连接于显示触控区D1的地相的接地主线132，接地支线131连接于接地主线。
接地主线132包括设置在显示触控芯片11下面的第一接线段1321和连接于第一接线段1321且位于触控连接线12外侧的第二接线段1322，第二接线段1322连接显示触控区D1的地相。
其中，接地连接线预先连接于显示触控区D1的地相和连接于非显示触控区D2中的用于绑定显示触控芯片11的绑定部件，且埋设在显示触控芯片11的下面，当显示触控芯片11绑定在非显示触控区D2时，显示触控芯片11的第二触控引脚112通过导电胶与绑定部件电性连接。
另外，第二接线段1322有两段，分别设置在整个触控连接线12的两侧，以和第一接线段1321连接形成包围整个触控连接线12的结构。将整个接地主线132包围住整个触控连接线12，当静电从外界窜入时，静电会想接触到接地主线132，可避免静电窜入触控连接线12，降低了静电进入触控连接线12的风险。
且两侧的第二接线段1322均连接于显示触控区D1的地相，以提高了将静电和干扰信号导出的效率。
在本实施例中，由于第一接线段1321最为接近第二触控引脚112，因此将接地支线131连接于第一接线段1321，以缩小连接距离。
接地支线131的宽度小于接地主线的宽度。
在第二实施例中，如图3，本第二实施例和第一实施例的不同之处在于，是基于第一实施例的基础上，触控连接线12设置有至少两组，接地主线还包括设置在相邻两组触控连接线12之间的第三接线段1323，第三接线段1323沿着两组触控连接线12之间的边缘延伸并形成一连接第一接地段1321的迂回线段。
在本第二实施例中，触控连接线12设置有两组，但并不限于此，可根据实际情况进行设置。
当显示触控芯片11具有两组触控引脚时，将每组触控引脚的第二触控引脚112均设置在两侧或四周的边缘区，第一触控引脚111设置在中间区域，这样的设置，一方面便于规划触控连接线12和接地连接线，另一方面以便接地连接线包围触控连接线12。
其中，第三接线段1323可以直接连接于第一接线段1321，也可以连接于位于两组触控引脚之间的两段接地支线131。本第二实施例中，采用连接于位于两组触控引脚之间的两段接地支线131，一方面接收材料，降低成本；了另一方面与两侧触控引脚之间的接地支线131连接，起到进一步降低干扰的目的。
而在两组触控连接线12之间设置迂回状的第三接线段1323，使得整个接地主线132从内到外彻底的包围了触控连接线12，当静电从内窜入时，先窜入第三接线段1323，降低了静电窜入触控连接线12的风险，进而保护了显示触控芯片11。
本申请还涉及一种显示触控装置，包括触控面板和设置在所述触控面板背面的铁背板，所述触控面板划分为显示触控区和设置在所述显示触控区一侧的非显示触控区，其中所述触控面板包括：
显示触控芯片，设置在所述非显示触控区，用于实现面板的显示和触控功能，包括用于连接所述显示触控区的以实现触控功能的第一触控引脚和空余的第二触控引脚；
触控连接线，设置在所述显示触控芯片和所述显示触控区之间，连接所述显示触控区和所述第一触控引脚；
接地连接线，设置在所述非显示触控区，所述接地连接线连接所述显示触控区的地相或接地的所述铁背板。
在本申请的显示触控装置中，当所述接地连接线连接所述显示触控区的地相时，所述接地连接线包括连接于所述第二触控引脚的接地支线和连接于所述显示触控区的地相的接地主线，
所述接地主线包括设置在所述显示触控芯片下面的第一接线段和连接于所述第一接线段且位于所述触控连接线外侧的第二接线段，
所述第二接线段有两段，分别设置在整个所述触控连接线的两侧，使得所述接地主线包围整个所述触控连接线，所述第二接线段连接所述显示触控区的地相。
在本申请的显示触控装置中，所述触控连接线设置有至少两组，所述接地主线还包括设置在相邻两组所述触控连接线之间的第三接线段，所述第三接线段沿着两组所述触控连接线之间的边缘延伸并形成一连接所述第一接地段的迂回线段。
在本申请的显示触控装置中，所述接地支线连接于所述第一接线段。
在本申请的显示触控装置中，所述接地支线的宽度小于所述接地主线的宽度。
在本申请的显示触控装置中，所述接地支线通过导电胶和所述第二触控引脚连接。
在本申请的显示触控装置中，当所述接地连接线连接所述铁背板时，所述接地连接线通过FPC柔性电路板连接于所述铁背板。
相较于现有技术的触控面板及显示触控装置，本申请的触控面板及显示触控装置将空余的第二触控引脚通过接地连接线连接于触控面板的地相或接地的铁背板，当有干扰信号或静电窜入第二触控引脚时，干扰信号和静电会经接地连接线导走，避免了显示触控芯片内部信号的相互干扰和避免了显示触控芯片内部电路被静电击伤；解决了现有的触控面板及显示触控装置由于闲置的触控引脚，容易接收外界静电和显示干扰信号，导致触控效果不佳的技术问题。
