对于所述第一连接部、第二连接部、第三连接部和第四连接部中的至少一个连接部，该连接部所在第一触控电极的其他至少两个连接部在所述基材上的正投影的中心的第一直线连线沿第一方向延伸，该连接部所在的第二触控电极的其他至少两个连接部在所述基材上的正投影的中心的第二直线连线沿第二方向延伸，第一直线连线与第二直线连线相交于一相交点，该连接部在所述基材上的正投影的中心位于所述相交点远离所述开孔区域中心的一侧，该连接部在所述基材上的正投影的中心与所述开孔区域中心的直线连线在第一方向上的正投影的长度大于等于所述相交点与所述开孔区域中心的直线连线在第一方向上的正投影的长度，该连接部在所述基材上的正投影的中心与所述开孔区域中心的直线连线在第二方向上的正投影的长度大于等于所述相交点与所述开孔区域中心的直线连线在第二方向上的正投影的长度。
采用上述触控面板，通过对开孔区域周围的第一触控电极的第一子电极和第二触控电极的第二子电极的形状以及连接关系进行设计，避免了使用额外的架桥结构绕过开孔区域连接同一第一触控电极中的被开孔区域隔断两相邻第一子电极或同一第二触控电极中的被开孔区域隔断两相邻第二子电极。在保证开孔区域周围的第一子电极和第二子电极的触控功能的同时，降低了工艺难度，增强了抗静电能力。
本公开一些实施例提供一种触控显示面板，图1示出了本公开一些实施例的 触控显示面板的平面结构示意图，图2示出图1中所述触控显示面板沿A-A’的截面结构示意图。如图1和图2所示，触控显示面板1000包括显示面板100和位于显示面板100显示面一侧的触控面板200。触控面板200通过第一粘合剂301贴附在显示面板100的显示面一侧，显示面板100例如为OLED显示面板，触控面板200采用外挂方式与显示面板贴合形成触控显示面板。本领域技术人员可以理解的是，在其他实施例中，触控面板200也可以集成在显示面板100内，采用IN-CELL的方式形成触控显示面板。在一些实施例中，触控显示面板1000的长宽比为2～2.5，例如为2.14。在一些实施例中，触控显示面板1000的四个角处为圆角，即触控显示面板1000在四个角处具有弧形边缘。
如图1和图2所示，在一些实施例中，触控显示面板1000还包括位于触控面板200远离显示面板一侧的偏光片400，贴附在位于触控面板200远离显示面板一侧。触控显示面板1000包括触控显示区域AA以及位于触控显示区域AA中的开孔区域HA。开孔区域HA贯穿显示面板100、触控面板200以及偏光片400。本领域技术人员可以理解的是，在一些实施例中，偏光片400可以省略。
本公开中所述的触控显示区域AA指的是触控显示面板的屏幕区域，对应显示面板100的显示区域和触控面板的触控区域。可以采用机械冲压打孔、激光打孔等方式在开孔区域HA中开孔，用于放置摄像头等组件。在一些实施例中，可以将触控面板200与显示面板100贴合后同时形成贯穿两者的开孔。在另一实施例中，还可以对触控面板200与显示面板100两者分别开孔，然后再将两者贴合，使得两者的开孔对应连通为一贯穿触控面板200与显示面板100两者的开孔。
对于显示面板100来说，显示面板100包括开孔区域HA和围绕开孔区域HA的有效显示区域DA，对于触控面板200来说，显示面板100包括开孔区域HA和围绕开孔区域HA的有效显示区域TA。有效显示区域DA和有效显示区域TA，两者可以统称为有效触控显示区域。
在一些实施例中，如图1和2所示，触控显示面板1000还包括盖板500，盖板500通过第二粘合剂302贴合在偏光片400远离触控面板200的一侧，用于起到保护其他组件的作用。
以下具体解释触控面板200的具体结构，本公开一些实施例提供一种触控面板，图3示出了根据本公开一些实施例的触控面板的局部平面结构示意图。如图3所示，触控面板200包括：基材201以及设置在基材201上的多个第一触控电 极210和多个第二触控电极220。所述多个第一触控电极210沿第一方向X延伸，至少一个第一触控电极210包括多个相互电连接的第一子电极211；所述多个第二触控电极220沿第二方向Y延伸，第二方向Y与第一方向X相交，例如第二方向Y与第一方向X垂直，至少一个第二触控电极220包括多个相互电连接的第二子电极221。在多个第一触控电极210和所述多个第二触控电极220的相交处设置有多个连接部230，至少一个连接部230位于沿第一方向X相邻的两个第一子电极211之间并将所述相邻的两个第一子电极221电连接，并且位于沿第二方向Y相邻的两个第二子电极221之间并将所述相邻的两个第二子电极221电连接，在所述至少一个连接部230处，所述第一触控电极210和第二触控电极220彼此电绝缘。
结合图1和后续的图10-13，可以认为，每个第一触控电极10包括多个相互电连接的第一子电极211以及位于相邻的两个第一子电极211之间并将相邻的两个第一子电极211电连接的多个第一连接子部2301，每个第二触控电极20包括多个相互电连接的第二子电极221和位于相邻的两个第二子电极221之间并将相邻的两个第二子电极221电连接的多个第二连接子部2302。第一连接子部2301和第二连接子部2302具有部分重叠面积，且它们构成的层叠结构为连接部230。所述触控面板200具有开孔区域HA，开孔区域HA被有效触控区域TA所包围。第一触控电极210和第二触控电极220以及连接部230均位于有效触控区域TA中。如图3所示，所述连接部230包括第一连接部231、第二连接部232、第三连接部233和第四连接部234，所述开孔区域HA被所述第一连接部231、第二连接部232、第三连接部233和第四连接部234围绕，所述第一连接部231、第二连接部232、第三连接部233和第四连接部234相较于其他连接部230更加靠近开孔区域HA。其中所述第一连接部231和第二连接部232在第一方向X上相邻且均与同一第一子电极211(记为第一子电极11，见图3)电连接，所述第三连接部233和第四连接部234在第一方向X上相邻且均与同一第一子电极211(记为第一子电极12，见图3)电连接，所述第一连接部231和第三连接部233在第二方向Y上相邻且均与同一第二子电极221(记为第二子电极22，见图3)电连接，所述第二连接部232和第四连接部234在第二方向Y上相邻且均与同一第二子电极221(记为第二子电极21，见图3)电连接。
对于所述第一连接部231、第二连接部232、第三连接部233和第四连接部 中234的至少一个连接部230，本实施例中，以第二连接部232为例进行说明。该第二连接部232所在第一触控电极210的其他至少两个连接部在所述基材上的正投影的中心的第一直线连线沿第一方向延伸，例如为该第二连接部232所在第一触控电极210在所述基材201上的正投影的沿第一方向X的直线状中线v。该第二连接部232所在的第二触控电极220的其他至少两个连接部在所述基材201上的正投影的中心的第二直线连线沿第二方向延伸，例如为该第二连接部232所在的第二触控电极220在所述基材201上的正投影的沿第二方向Y的直线状中线h。第一直线连线和第二直线连线相交于一相交点M，可以认为该相交点M位于该第二连接部232所在的第一触控电极210以及该第二连接部232所在的第二触控电极220的交叉处。该第二连接部232在所述基材201上的正投影的中心位于所述相交点M远离所述开孔区域HA的中心N的一侧，该第二连接部232在所述基材201上的正投影的中心与所述开孔区域HA中心N的直线连线在第一方向X上的正投影的长度大于等于所述相交点M与所述开孔区域HA的中心N的直线连线在第一方向X上的正投影的长度，该连接部232在所述基材201上的正投影的中心与所述开孔区域HA的中心N的直线连线在第二方向Y上的正投影的长度大于等于所述相交点M与所述开孔区域HA的中心N的直线连线在第二方向Y上的正投影的长度。整体上看，该第二连接部232在所述基材201上的正投影的中心相较于所述相交点M更加远离所述开孔区域HA的中心N。
在一些实施例中，该连接部232在所述基材201上的正投影的中心与所述开孔区域HA中心N的直线连线长度大于所述相交点M与所述开孔区域HA的中心N的直线连线长度。
在一些实施例中，该连接部232不位于其所在第一触控电极210的其他至少两个连接部在所述基材上的正投影的中心的第一直线连线上，例如该连接部不位于该第二连接部232所在第一触控电极210在所述基材201上的正投影的沿第一方向X的直线状中线v上。在一些实施例中，该连接部与其所在第一触控电极210的其他连接部中至少一个的连接与直线状中线v为一个夹角。例如，所述夹角取值范围为锐角，即大于0°，且小于90°。例如，所述夹角取值范围为10°～80°，20°～70°，30°～60°，40°～50°。当然，也可以是其他非直角的锐角取值。
该连接部232不位于所在的第二触控电极220的其他至少两个连接部在所述 基材201上的正投影的中心的第二直线连线上，例如该连接部232不位于该连接部232所在的第二触控电极220在所述基材201上的正投影的沿第二方向Y的直线状中线h上。。在一些实施例中，该连接部与其所在第二触控电极220的其他连接部中至少一个的连接与直线状中线h为一个夹角，所述夹角取值范围为锐角，即大于0°，且小于90°。例如，所述夹角取值范围为10°～80°，20°～70°，30°～60°，40°～50°。当然，也可以是其他非直角的锐角取值。
在上述实施例中，该第二连接部232所在第一触控电极210的除了该第二连接部232的其他连接部230在基材201上的正投影的中心(以下可以简称为其他连接部230的中心)均位于该第一触控电极210在所述基材201上的正投影的沿第一方向X的直线状中线v上，该第二连接部232所在第二触控电极220的除了该第二连接部232的其他连接部230在基材201上的正投影的中心均位于该第二触控电极220在所述基材201上的正投影的沿第二方向Y的直线状中线h上。该种结构便于触控面板200的设计。
基于上述设计，可以使得位于开孔区域HA附近的与该第二连接部232电连接的第一子电极11和第二子电极21具有较大的面积，以保障开孔区域HA附近触控子电极(包括第一子电极和第二子电极)的触控效果，避免在靠近开孔区域HA附近的区域触控失效。
在本文中，除非另外限定，连接部的中心通常指的是该连接部在基材上的正投影的中心。
在一些实施例中，相邻的第一子电极只通过第一连接部电连接，相邻的第二子电极只通过第二连接部电连接。
在一些实施例中，开孔区域的中点到第一连接部，第二连接部，第三连接部，第四连接部在基材上正投影中心的距离中的至少两个不同。
在一些实施例中，开孔区域的中点到第一连接部，第二连接部，第三连接部，第四连接部基材上正投影中心的距离均不相同。
以下为更加直观地了解上述实施例的优点，将上述实施例与如下介绍的相关技术方案进行对比说明。
图4示出了相关技术中的触控面板200’的局部结构示意图。如图4所示在相关技术中，触控面板200’包括基材201以及设置在基材201上的多个第一触控 电极210和多个第二触控电极220。所述多个第一触控电极210沿第一方向X延伸，至少一个第一触控电极210包括多个相互电连接的第一子电极211；所述多个第二触控电极220沿第二方向Y延伸，第二方向Y与第一方向X相交，例如第二方向Y与第一方向X垂直，至少一个第二触控电极220包括多个相互电连接的第二子电极221。在多个第一触控电极210和所述多个第二触控电极220的相交处设置有多个连接部230，至少一个连接部230位于沿第一方向X相邻的两个第一子电极221之间并将所述相邻的两个第一子电极221电连接，并且位于沿第二方向Y相邻的两个第二子电极221之间并将所述相邻的两个第二子电极221电连接，在所述至少一个连接部230处，所述第一触控电极210和第二触控电极220彼此电绝缘。如图4所示，对于任一第一触控电极210，其上的多个连接部230的中心均位于该第一触控电极210在基材201上的正投影的沿第一方向X的中线上，对于任一第二触控电极220，其上的多个连接230的中心均位于该第二触控电极220在基材201上的正投影的沿第二方向Y的中线上。
为了实现全面屏设计，需要在触控面板200’上打孔，由此设计开孔区域HA，本领域中开孔的直径一般为3mm-5mm，例如为4mm。为避免触控面板200’中的开孔对触控效果造成较大的影响，通常将开孔区域HA的中心设置在相邻四个连接部的中心形成的矩形的中心附近，该四个相邻的连接部的中心分别位于该矩形的四个顶点处。此时可以尽量避免开孔区域覆盖或者进可能少的覆盖连接部230，使得尽可能多的第一触控电极210和/或第二触控电极220保持信号的畅通。
如图4所示，开孔区域HA的中心位于第一电极部231、第二连接部232’、第三连接部233、第四连接部234的中心为四个顶点的矩形的中心附近。开孔区域HA覆盖第二连接部232’，若在开孔区域HA打孔，则第二连接部232’可能被去除，此时第二连接部232’所在的第一触控电极210会出现断路，即原本由第二连接部232’电连接的其所在的第一触控电极210的第一子电极11和第一子电极13断开，第二连接部232’所在的第二触控电极220会出现断路，即原本由第二连接部232’电连接的其所在的第二触控电极220的第二子电极21和第二子电极23断开。为了使得触控第二连接部232’所在的第一触控电极210和第二触控电极220保持信号畅通，相关技术中可以通过额外的第一架桥电连接第一子电极11和第一子电极13，并且可以通过额外的第二架桥电连接第二子电极21和第二子电极23，第一架桥和第二架桥均绕开开孔区域HA设置。然而通过绕开开孔 区域HA进行金属架桥后，会导致开孔区域HA附近的由第一架桥电连接第一子电极11和第一子电极13，以及由第二架桥电连接第二子电极21和第二子电极23抗静电能力差。并且如图4所示，第一子电极11和第二子电极21由于被开孔区域HA截去一部分导致两者的面积较小，即使通过架桥的方式保证第一子电极11所在的第一触控电极210和第二子电极21所在的第二触控电极220均保持信号畅通，第一子电极11和第二子电极21处的触控效果也会较差，导致在该位置处的触控不能识别。
比较图4所示的相关技术与图3所示的实施例方案，可见图4中的第二连接部232’的中心对应图3中所示的相交点M，图3所示的实施例的方案可以认为是将图4所示的相关技术中第二连接部232’朝向远离开孔区域HA的方向移动而获得，例如移动至图3中第二连接部232所在的位置，并且改变第一子电极11、第一子电极13、第二子电极21，第二子电极23的形状。使得移动后的第二连接部232(如图3所示)避开了开孔区域HA的位置，且第一子电极11和第一子电极13通过第二连接部232电连接，第二子电极21和第二子电极23通过第二连接部232电连接。不需要额外设置金属架桥，避免了抗静电能力差的问题。并且比较图3和图4所示，图3中的第一子电极11相较于图4所示的相关技术中的第一子电极11的面积明显增大，图3中的第二子电极21相较于图4所示的相关技术中的第二子电极21的面积明显增大，基于该种设置在图3所示的实施例中，位于开孔区域HA附近的与该第二连接部232电连接的第一子电极11和第二子电极21具有较大的面积，以保障开孔区域HA附近触控子电极(包括第一子电极和第二子电极)的触控效果，避免在靠近开孔区域HA附近的区域触控失效。
本领域技术人员可以理解的是，触控面板200’上的开孔需要与显示面板上的开孔对准，在一些特定情况下，当第一子电极211和第二子电极221采用如图4所示的排列方式规则排布且第一子电极211和第二子电极221的尺寸为某一设定值时，触控面板200’上的开孔的中心可能会靠近某一连接部，即使采用在有相关技术的方案的基础上移动该连接部也很难避免采用架桥的方式来保证该连接部所在第一触控电极210和/或第二触控电极220的信号通畅。此时可以通过调整第一触控电极210的宽度和/或第二触控电极220宽度来使得触控面板200’上的开孔的中心位于在相邻四个连接部的中心形成的矩形的中心附近。这里所说的 第一触控电极210的宽度可以认为是图4中具有菱形或正方形形状的第一子电极211在第二方向Y上的对角线的长度，第二触控电极220的宽度可以认为是图4中具有菱形或正方形形状第二子电极221在第一方向X上的对角线的长度。
继续参见图3，继续以第二连接部232为例，该第二连接部232位于沿第一方向X彼此相邻的第一个第一子电极11和第二个第一子电极13之间，且与所述第一个第一子电极11和第二个第一子电极13均电连接，所述第一个第一子电极11比所述第二个第一子电极13更靠近所述开孔区域HA，所述触控面板200还包括位于所述第二个第一子电极13远离所述第一个第一子电极11一侧的第三个第一子电极14，所述第三个第一子电极14与所述第二个第一子电极13彼此相邻且通过第五连接部235电连接。所述第三个第一子电极14为正常第一子电极。这里所说的正常第一子电极指的是有效触控区域TA中的基本具有规则图案，例如为菱形、正方形、网格线等，的第一子电极。
该第二连接部232位于沿第二方向Y彼此相邻的第一个第二子电极21和第二个第二子电极23之间，且与所述第一个第二子电极21和第二个第二子电极23均电连接，所述第一个第二子电极21比所述第二个第二子电极23更靠近所述开孔区域HA，所述触控面板200还包括位于所述第二个第二子电极23远离所述第一个第二子电极21一侧的第三个第二子电极24，所述第三个第二子电极24与所述第二个第二子电极23彼此相邻且通过第六连接部236电连接。所述第三个第二子电极24为正常第二子电极。这里所说的正常第二子电极指的是有效触控区域TA中的基本具有规则图案，例如为菱形、正方形、网格线等，的第二子电极。
相较于图4所示的相关技术，图3所示的实施例可以认为是在图4所示的相关技术的基础上将第二连接部232’远离开孔区域HA的中心移动。相应的改变第一个第一子电极11和第二个第一子电极13的面积，具体地，增大第一个第一子电极11的面积，减小第二个第一子电极13的面积，同时相应地改变第一个第二子电极21和第二个第二子电极23的面积，具体地，增大第一个第二子电极21的面积，减小第二个第二子电极23的面积，使得位于开孔区域HA周围的第一子电极和/或第二子电极的面积避免过小，进而避免在该处触控不佳或触控失效的问题。
在一些实施例中，参见图3，所述第一个第一子电极11的面积不小于正常 第一子电极，例如为所述第三个第一子电极14的面积的50％，所述第二个第一子电极的面积不小于正常第一子电极，例如为所述第三个第一子电极14的面积的70％。所述第一个第二子电极21的面积不小于正常第二子电极，例如为所述第三个第二子电极24的面积的50％，所述第二个第二子电极的面积不小于正常第二子电极，例如为所述第三个第二子电极14的面积的70％。由此可以使得于开孔区域HA周围的第一子电极和/或第二子电极的面积避免过小，面积均一性好，进而避免在该处触控不佳或触控失效的问题。
图5-图7分别示出了一些实施例中的触控面板的局部平面结构示意图。图5所示的触控面板的平面结构相当于在相关技术基础上将第二连接部232和第四连接部234均进行类似图3所示的在相关技术基础上将第二连接部232远离开孔区域HA中心的移动；图6所示的触控面板的平面结构相当于在相关技术基础上将第二连接部232、第三连接部233和第四连接部234均进行类似图3所示的在相关技术基础上将第二连接部232远离开孔区域HA中心的移动；图7所示的触控面板的平面结构相当于在相关技术基础上将第一连接部231、第二连接部232、第三连接部233、第四连接部234均进行类似图3所示的在相关技术基础上将第二连接部232远离开孔区域HA中心的移动。
如图5-7所示，位于开孔区域HA周围的第一子电极11、第一子电极12、第二子电极21和第二子电极22中的至少一个的面积相对于相关技术增大，使得于开孔区域HA周围的第一子电极和/或第二子电极的面积避免过小，面积均一性好，进而避免在该处触控不佳或触控失效的问题。
在一些实施例中，如图7所示，通过在相关技术基础上将第一连接部231、第二连接部232、第三连接部233、第四连接部234远离开孔区域HA中心的移动，增加第一子电极11、第一子电极12、第二子电极21和第二子电极22的面积同时压缩与它们相邻的其他的第一子电极211和第二子电极221的面积。例如将第一连接部231远离开孔区域HA中心的移动，在增加第一子电极11的面积的同时压缩与第一子电极11相邻的第二子电极25的面积。
本领域技术人员可以理解的是，当相关技术中开孔区域HA具有预定大小时，可以采用图3，5-7中所示的实施例来进行改进。开孔区域HA的面积S满足如下公式：
2S1≤S≤4S1
其中，S1为正常第一子电极和正常第二子电极的面积的平均值。
当开孔区域HA过小，在相关技术中可能开孔区域HA周围不存在触控不佳或失效的问题，当开孔区域HA过大，即使采用图3，5-7中所示的实施例，也依然可能需要采用额外桥接的方式来保证第一触控电极210和/或第二触控电极220的信号导通。
在一些实施例中，正常第一子电极和正常第二子电极形状和面积均相同。
图8为图3中开孔区域HA处的局部放大图，图8中示出了开孔区域HA，位于开孔区域周围的第一子电极11、第一子电极12、第二子电极21和第二子电极22的一部分。如图8所示，第一子电极11、第一子电极12、第二子电极21和第二子电极22均位于有效触控区域TA中，有效触控区域TA围绕开孔区域HA。触控面板200还包括走线区域WA，走线区域WA围绕开孔区域HA设置，并位于有效触控区域TA和开孔区域HA之间。
如图8所示，触控面板200还包括位于走线区域WA的防裂环240，采用导电材料制成，所述防裂环240围绕所述开孔区域HA设置，为具有至少一个第一开口241的环形，所述防裂环240在所述第一开口241处断开。防裂环240用于防止在开孔区域HA打孔时的产生的裂纹的蔓延，避免有效触控区域TA受到影响。防裂环240为不连续的环形，避免导电材料制成的封闭环形导致信号屏蔽。
如图8所示，触控面板200还包括位于走线区域WA的防静电环250，防静电环250围绕所述防裂环240设置，为具有至少一个第二开口251的环形，第二开口251例如为Z型开口，防静电环250配置为防止静电进入有效触控区域TA造成不良影响。防静电环250在第二开口251处断开，为不连续的环形，避免导电材料制成的封闭环形导致信号屏蔽。第二开口251与所述第一开口241对齐。
如图8所示，触控面板200还包括位于走线区域WA和有效触控区域TA边界处的连接环260，连接环260围绕防静电环250。连接环260为不连续的环形，包括第一连接子环261、第二连接子环262、第三连接子环263和第四连接子环264。第一连接子环261和第二连接子环262在第一子电极11和第二子电极21的边界处断开，第二连接子环262和第三连接子环263在第二子电极21和第一子电极12的边界处断开，第三连接子环263和第四连接子环264在第一子电极12和第二子电极22的边界处断开，第一连接子环261和第四连接子环264在第一子电极11和第二子电极22的边界处断开。第一连接子环261、第二连接子环 262、第三连接子环263和第四连接子环264分别与第一子电极11、第二子电极21、第一子电极12、第二子电极22对应，并分别与第一子电极11、第二子电极21、第一子电极12、第二子电极22电连接。每个连接子环与其对应的子电极的相对位置关系基本一致。
以下主要以第三连接子环263及其对应的第一子电极12为例来进行解释说明。图9为图8中的结构沿B-B’的截面结构示意图。如图8和9所示，第三连接子环263与第一子电极12直接电接触，具体地，第三连接子环263位于第一子电极12远离基材201的一侧，并且第三连接子环263在基材201上的正投影落入第一子电极12在基材201上的正投影内。第三连接子环263与第一子电极12并联，可以降低第一子电极12的阻抗，减少通过第一子电极12的信号的衰减。第一子电极12可以采用透明导电材料例如ITO、IZO制成，第三连接子环263例如单层结构，可以采用金属材料制成，直接与第一子电极12搭接。
防裂环240和防静电环250中的至少一个例如可以为双层结构，包括第一子层和第二子层，第一子层与第一子电极12可以采用相同材料同层设置，第二子层可以与第三连接子环263采用相同材料同层设置。
如图8和图9所示，触控面板还包括位于第三连接子环263远离基材201一侧并且依次远离基材201设置的第一绝缘层270和第二绝缘层280。
在一些实施例中，第一子电极11、第二子电极21、第一子电极12、第二子电极22均采用相同材料同层设置。
在一些实施例中，图3还示出了触控面板200角部处的结构示意图，如图3所示，触控面板200的角为圆角，即触摸面板200在其角处具有弧形边缘。本领域技术人员可以理解的是，触控面板200具有四个角，图3中仅示出了一个角来举例说明。
如图3所示，触控面板200包括第七连接部237，第七连接部237位于触控面板200的弧形边缘附近，第七连接部237与至少一个与所述弧形边缘相邻的第一子电极211或第二子电极221电连接.。该第二连接部237所在第一触控电极210的其他至少两个连接部在所述基材上的正投影的中心的第五直线连线沿第一方向延伸，例如为该第七连接部232所在第一触控电极210在所述基材201上的正投影的沿第一方向X的直线状中线v1。该第七连接部237所在的第二触控电极220的其他至少两个连接部在所述基材201上的正投影的中心的第六直线 连线沿第二方向延伸，例如为该第七连接部237所在的第二触控电极220在所述基材201上的正投影的沿第二方向Y的直线状中线h1。第五直线连线和第六直线连线相交于一相交点M1，可以认为该相交点M1位于该第七连接部237所在的第一触控电极210以及该第七连接部237所在的第二触控电极220的交叉处。该第七连接部237在所述基材201上的正投影的中心位于所述相交点M1远离所述弧形边缘的一侧。
在图4所示的相关技术中，存在与图3中的第七连接部237相应的第七连接部237’，如图4所示，第七连接部237’其位于触控面板200’的弧形边缘附近，其与至少一个与所述弧形边缘相邻的第一子电极211或第二子电极221电连接。第七连接部237’所在第一触控电极210的所有连接部在所述基材上的正投影的中心均在一条直线上，第七连接部237’所在第二触控电极220的所有连接部在所述基材上的正投影的中心均在一条直线上。此时，与所述弧形边缘相邻的第一子电极211或第二子电极221面积过小，在弧形边缘附近处可能会存在触控失效的问题。
相较于图4所示的相关技术，图3所示的实施例可以认为是在图4所示的相关技术的基础上，将第七连接部237’远离弧形边缘移动，由此可以相应的增加与所述弧形边缘相邻的第一子电极211或第二子电极221面积，避免在该处存在触控不佳或触控失效的问题。
本领域技术人员可以理解的是，图5-7中的触控面板亦可包括如图3所示的弧形边缘区域，在此不再赘述。
图10为图3中触控面板的局部放大示意图，示出了一个连接部以及与该连接部相邻且电连接的两个第一子电极和两个第二子电极，以两个第一子电极均为正常第一子电极，两个第二子电极均为正常第一子电极进行举例说明。
如图10所示，连接部230包括第一连接子部2301和第二连接子部2302。第一连接子部2301沿第一方向X延伸，电连接沿第一方向X相邻的两个第一子电极211。第二连接子部2302沿第二方向Y延伸，电连接沿第二方向Y相邻的两个第二子电极21。第一连接子部2301和第二连接子部2302相互电绝缘，它们之间具有第一绝缘层270。
图11为图10中的结构沿线C-C’的截面示意图。如图10和图11所示，第一子电极211和第二子电极221位于同一电极层，记为第一电极层291，该第一 电极层291设置在基材201上，例如采用透明导电材料例如为ITO、IZO等制成。第二连接子部2302可以与沿第二方向Y相邻的两个第二子电极221为一体结构，即第二连接子部2302亦位于第一电极层291中，第二连接子部2302与包括第一子电极211的第一触控电极210和包括第二子电极221的第二触控电极220同层设置。第一连接子部2301位于第二电极层292。第二电极层292位于第一电极层291远离基材201一侧，例如采用金属材料制成。且第一电极层291和第二电极层292之间设置有第一绝缘层270。第一绝缘层270中设置有过孔271，第一连接子部2301的一个端部通过过孔271与一个第一子电极211电连接，第一连接子部2301的另一个端部通过过孔271与另一个第一子电极211电连接，使得两个第一子电极11通过桥接的方式电连接。如图11所示，触控面板200还包括位于第二电极层292远离基材201一侧的第二绝缘层280，用于保护第一连接子部2301。

图13为图12中的结构沿线D-D’的截面示意图。如图12和图13所示，第一子电极211和第二子电极221位于同一电极层，记为第一电极层291，该第一电极层291设置在基材201上，例如采用透明导电材料例如为ITO、IZO等制成。第一连接子部2301可以与沿第一方向X相邻的两个第一子电极211为一体结构，即第一连接子部2301亦位于第一电极层291中，第一连接子部2301与包括第一子电极211的第一触控电极210和包括第二子电极221的第二触控电极220同层设置。第二连接子部2302位于第二电极层292。第二电极层292位于第一电极层291远离基材201一侧，例如采用金属材料制成。且第一电极层291和第二电极层292之间设置有绝缘层270。绝缘层270中设置有过孔272，第二连接子部2302的一个端部通过过孔272与一个第二子电极221电连接，第二连接子部2302 的另一个端部通过过孔272与另一个第二子电极221电连接，使得两个第二子电极221通过桥接的方式电连接。如图11所示，触控面板200还包括位于第二电极层292远离基材201一侧的第二绝缘层280，用于保护第二连接子部2302。
本文中所说的连接部230是指由图10或图12中虚线框表示的部分，包括第一连接子部2301和第二连接子部2302的层叠结构，连接部230在基材100上的正投影的中心由如图10或图12中的S表示，即为图10或图12中虚线框表示的部分的中心，中心S所在的位置可以用于表示连接部230的所处位置。本领域技术人员可以理解的是在图3-7中，为了方便绘图，仅以“+”来表示连接部230，以“+”的中心表示连接部230在基材201上的正投影的中心S。
在一些实施例中，连接部230中的第一连接子部2301可以为一条或更多条，连接部230中的第二连接子部2302亦可以为一条或更多条。图10和图12中，仅给出了连接部230具有一条第一连接子部2301和一条第二连接子部2302的示例。
图14为根据本公开一些实施例的触控面板的局部放大示意图，如图14所示，连接部230具有两条第一连接子部2301和一条第二连接子部2302。图14中所示的结构相较于图10中所示的结构增加了一条第一连接子部2301，第一连接子部2301所在层以及与两相邻的第一子电极11的连接关系及连接方式与图6中所示的结构基本上相同，在此不再赘述。
在一些实施例中，如图14和图17所示，所述连接部230为虚线框所示的长方形。在一些实施例中，所述连接部230在第二方向Y上长度大于在第一方向X上的长度。在一些实施例中，所述连接部230在第二方向Y上长度小于等于在第一方向X上的长度。在一些实施例中，所述连接部230在第二方向Y上长度约为0.6mm，在第一方向X上的长度为0.55mm。在另一些实施例中，所述连接部30在第二方向Y上长度范围约为0.5-0.7mm，在第一方向X上的长度范围约为0.45-0.65mm。此处的约是指不严格限定数值边界，允许工艺和测量误差范围内的数值。
本领域技术人员可以理解的是第一连接子部2301和/或第二连接子部2302可以为直条状(如图10，12所示)、弯折条状(如图14所示)、弯曲条状等，只要能够保证与其电连接的两个第一子电极或两个第二子电极电导通即可，在此不作具体限定。
本领域技术人员可以理解是，前述的例举的连接两个正常第一子电极和两个正常第二子电极的连接部230的结构及连接关系同样适用于连接非正常第一子电极和/或非正常第二子电极的连接部。
在前述实施例中，均以相邻的第一子电极211和第二子电极221的边界为直线状边界进行举例说明，然而在一些实施例中，相邻的第一子电极211和第二子电极221的边界可以为其他形状，例如为折线状。以下以图7中的标号为11的第一子电极211和标号为25的第二子电极221的边界来举例说明。
图15为根据本公开一些实施例的触控面板的局部放大示意图，仅示出了标号为11的第一子电极211和标号为25的第二子电极221的一部分以及它们之间的边界。如图15所示，第一子电极211和第二子电极221的边界60呈折线状，该边界60包括多个首尾相接的折线段，任意两相邻折线段之间均呈钝角β，该钝角β的范围为120°～140°。例如，任意两相邻折线段之间的钝角β均为130°。相较于第一子电极211和第二子电极221之间的边界呈直线状(图15中的条状虚线示出了呈直线状的边界)的情况，该种设置可以进一步调节相邻的第一子电极211和第二子电极221的尺寸，如图7和图15所示，可以进一步增大标号为11的第一子电极211的尺寸，缩小标号为25的第二子电极221的尺寸，使得两者的尺寸更加均衡。在一些实施例中，第一子电极211和第二子电极221的边界60呈折线状，该边界60包括多个首尾相接的折线段，任意两相邻折线段之间均呈钝角β，该钝角β的范围为120°～140°，且至少两个钝角取值不同。
图16A为图15中区域Z的放大示意图，如图16A所示，标号为11的第一子电极211和标号为25的第二子电极221之间的边界60包括位于第一子电极211和第二子电极221之间的第一虚设电极62和第二虚设电极64，第一虚设电极62和第二虚设电极64均为折线状，且两者基本上平行设置，这里所说的第一虚设电极62和第二虚设电极64基本平行指的是，第一虚设电极62和第二虚设电极64均包括多个折线段，第一虚设电极62的每个折线段均与第二虚设电极64对应的折线段平行设置。且第一虚设电极62相较于第二虚设电极64更加靠近第一子电极211，第二虚设电极64相较于第一虚设电极62更加靠近第二子电极221。边界60还包括位于第一子电极211和第一虚设电极62之间的第一间隔61、位于第一虚设电极62和第二虚设电极64之间的第二间隔63，以及位于第二虚设电极64和第二子电极221之间的第三间隔65。第一间隔61使得第一子 电极211和第一虚设电极62电绝缘，第二间隔63使得第一虚设电极62和第二虚设电极64电绝缘，第三间隔65使得第二虚设电极64和第二子电极221电绝缘。第一间隔61、第二间隔63以及第三间隔65均为折线状，且三者基本上平行设置。
在一些实施例中，第一虚设电极62和第二虚设电极64均处于浮置状态。
在一些实施例中，第一虚设电极62、第二虚设电极64、第一子电极211和第二子电极221采用相同材料同层设置。该种设置可以使得第一子电极211和第二子电极221所在的区域与边界60所在的区域的透过率尽可能地接近，使得整个触控面板的透过率尽可能地均匀。
在一些实施例中，图16B为图15中区域Z的放大示意图，如图16B所示，其与图16A所示的实施例的区别在于，标号为11的第一子电极211和标号为25的第二子电极221之间的边界60仅包括一个虚设电极66，虚设电极66均包括多个折线段。边界60还包括位于第一子电极211和虚设电极66之间的第一间隔61’、以及位于虚设电极66和第二子电极221之间的第三间隔65’。第一间隔61’使得第一子电极211和虚设电极66电绝缘，第三间隔65’使得虚设电极66和第二子电极221电绝缘。第一间隔61、及第三间隔65均为折线状，且两者基本上平行设置。相较于图16A所示的实施例，本实施例中，由于减少了一个虚设电极和一个间隔，相邻的第一子电极211和第二子电极221的面积可以做得更大，提升触控效果。更进一步地，图16B中各间隔的宽度相较于图16A中各间隔的宽度可以做得更小，例如缩小一半，此时相邻的第一子电极211和第二子电极221的面积可以做得更大，提升触控效果，并且有利于消影。
本领域技术人员可以理解的是，任意相邻的第一子电极211和第二子电极221之间的边界均可以采用上述类似的设置。
图17示出了根据本公开一些实施例的触控面板的局部放大示意图，图17主要示出了一个连接部230的具体结构及该连接部周边的结构。连接部230为图17中虚线框表示的部分，包括第一连接子部2301和第二连接子部2302构成的层叠结构，为所述层叠结构所在的规则区域。与图14中示出的连接部230类似，图17中的连接部230包括两个第一连接子部2301(即第一第一连接子部311和第二第一连接子部312)和一个第二连接子部2302以及与第一第一连接子部311的两端分别电连接的第一过孔411和第二过孔412、与第二第一连接子部312的 两端分别电连接的第三过孔413和第四过孔414。在本文中，连接部可以为一规则区域(例如具有矩形或其他形状)，连接部在基材上的正投影的中心，可为该规则区域在基材上的正投影的中心。
如图17所示，连接部230连接位于上侧的第一子电极211和位于下侧的第一子电极211，并且连接部230连接位于左侧的第二子电极221和位于右侧的第二子电极221。任意相邻的第一子电极211和第二子电极221之间的边界60为折线状，类似图15中所示出的边界。图17中仅示出了边界60靠近连接部230的一部分。

在一些实施例中，第一连接子部2301在第一方向X上的最大长度与第二连接子部2302在第一方向X上的最小长度的比值在2.75和3.25之间，例如为3。
在一些实施例中，所述第二连接子部2302的边缘包括第一折线段321，第二折线段322，第三折线段323和第四折线段324。在一些实施例中，第一折线段321与第四折线324段平行，且定义为与第一方向X和第二方向Y均相交的第三方向Z1。在一些实施例中，所述第二折线段322与第三折线段323平行，且定义为与第一方向X，第二方向Y，第三方向Z1均相交的第四方向Z2。第三方向Z1和第二方向Y的锐角夹角可以为5°～25°，例如为20°。第四方向Z2和第二方向Y的锐角夹角可以为5°～25°，例如为20°。
