具体实施方式
下面结合附图和实施例对本公开作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与发明相关的部分。
需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。
另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。
应该理解的是，尽管在这里可使用术语第一、第二等来描述不同的元件，但是这些元件不应受这些术语的限制。这些术语仅是用来将一个元件与另一个元件区分开来。例如，在不脱离示例实施例的范围的情况下，第一元件可以被命名为第二元件，类似地，第二元件可以被命名为第一元件。如在这里使用的术语“和/或”包括一个或多个相关所列的项目的任意组合和所有组合。
应该理解的是，当元件或层被称作“形成在”另一元件或层“上”时，该元件或层可以直接地或间接地形成在另一元件或层上。也就是，例如，可以存在中间元件或中间层。相反，当元件或层被称作“直接形成在”另一元件或层“上” 时，不存在中间元件或中间层。应当以类似的方式来解释其它用于描述元件或层之间的关系的词语(例如，“在...之间”与“直接在…之间”、“相邻的”与“直接相邻的”等)。
本文中使用的术语仅是为了描述特定实施例的目的，而不意图限制实施例。如本文中所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式。还将理解的是，当在此使用术语“包含”和/或“包括”时，说明存在所述特征、整体、步骤、操作、元件和/或组件，但不排除存在或附加一个或多个其它特征、整体、步骤、操作、元件、组件和/或它们的组合。
在本文中，如无特别说明，表述“位于同一层”、“同层设置”一般表示的是：第一部件和第二部件可以使用相同的材料并且可以通过同一构图工艺形成。表述“位于不同层”、“不同层设置”一般表示的是：第一部件和第二部件通过不同构图工艺形成。
相关技术中的穿戴式电子手表中包括触控显示屏和电子元器件，发明人发现电子手表上的触控显示屏无法实现类似传统机械表的机械轮盘功能的数字轮盘功能。对相关的穿戴式产品来说，使用者很难通过滑动手表触控屏幕边沿外围来实现类似于机械手表的机械轮盘功能。
本公开提供一种触控面板，包括：基材以及设置在基材上的多个第一触控电极和多个第二触控电极。多个第一触控电极沿第一方向延伸，至少一个第一触控电极包括多个相互电连接的第一子电极；多个第二触控电极沿第二方向延伸，第二方向与第一方向相交，至少一个第二触控电极包括多个相互电连接的第二子电极。在多个第一触控电极和所述多个第二触控电极的相交处设置有多个连接部，至少一个连接部位于沿第一方向相邻的两个第一子电极之间并将所述相邻的两个第一子电极电连接，并且位于沿第二方向相邻的两个第二子电极之间并将所述相邻的两个第二子电极电连接，在所述连接部处，所述第一触控电极和第二触控电极彼此电绝缘。所述触控面板上设有触控区域以及围绕触控区域的非触控区域，所述多个第一触控电极、多个第二触控电极均位于所述触控区域中，所述多个连接部包括沿第一方向依次远离所述非触控区域布设的第一连接部、第二连接部以及第三连接部，所述第一连接部、第二连接部以及第三连接部沿第一方向依次两两相邻，所述第一连接部在基材上的正投影的中心与所述第二连接部在基材上的正投影的中心之间的距离小于所述第二连接部在基材上的正投影的中心 与所述第三连接部在基材上的正投影的中心之间的距离。
在一些实施例中，所述第一连接部是最靠近所述非触控区域的连接部。
采用该种触控面板，可以增大位于触控面板的触控区域和非触控区域的边界处的第一子电极和第二子电极的面积，改善触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，实现数字轮盘功能。
本文中所述的数字轮盘功能指的是滑动触控面板的触控区域的边缘区而触发的触控功能。例如对于包括触控面板的电子装置，例如为电子手表，人体手指滑动屏幕边缘区激发滑动触控信号，由电子装置的控制器接收滑动触控信号，并在电子手表上进行特定显示，以此实现数字轮盘功能。通过数字轮盘功能的实现，可以开发出更加丰富多彩的生活、学习和工作应用场景。例如我们可以通过在电子装置，例如为电子手表，的边缘区的上下滑动来设定闹钟的定时、屏幕亮度的调节、声音大小的调节、播放音乐速度的快慢以及多功能画面的切换等。
图1为根据本公开一些实施例的触控面板的平面结构示意图。如图1所示，本公开一些实施例提供一种触控面板，触控面板包括基材100以及设置在基材100上的多个第一触控电极10和多个第二触控电极20。多个第一触控电极10沿第一方向X延伸，每个第一触控电极10包括多个相互电连接的第一子电极11。多个第二触控电极20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。每个第二触控电极20包括多个相互电连接的第二子电极21。在多个第一触控电极10和所述多个第二触控电极20的相交处设置有多个连接部30，每个连接部30位于沿第一方向X相邻的两个第一子电极11之间并将所述相邻的两个第一子电极11电连接，并且位于沿第二方向Y相邻的两个第二子电极21之间并将所述相邻的两个第二子电极21电连接，在所述连接部30处，所述第一触控电极10和第二触控电极20彼此电绝缘。
结合图1和后续的图6-9，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11以及位于相邻的两个第一子电极11之间并将相邻的两个第一子电极11电连接的多个第一连接子部31，每个第二触控电极20包括多个相互电连接的第二子电极21和位于相邻的两个第二子电极21之间并将相邻的两个第二子电极21电连接的多个第二连接子部32。第一连接子部31和第二连接子部32具有部分重叠面积，且它们构成的层叠结构为连接部30。
所述触控面板10上设有触控区域TA以及围绕触控区域TA的非触控区域 NA，所述多个第一触控电极10、多个第二触控电极20均位于所述触控区域TA中。
本文中，第一触控电极10可以是触控驱动电极和触控感应电极中的一个，第二触控电极20可以是触控驱动电极和触控感应电极中的一个另一个。其中触控驱动电极用于接入触控发射信号，触控感应电极用于基于触控发射信号感应出来的触控感应信号。
本领域技术人员可以理解的是图1仅仅是示意性的示出了触控面板的平面结构，用于表明第一触控电极10、第二触控电极20以及连接部30之间的相对位置关系，并不用于指示上述各组件的实际尺寸，在实际应用中，第一触控电极10的第一子电极11、第二触控电极20的第二子电极21以及连接部30的尺寸相对于整个触控面板来非常小。
图2为图1中A区域的平面示意图，图2示意性地示出了触控面板周边区域的平面结构，图2仅示出了触控区域TA的一部分，省略了非触控区域NA。结合图1和图2可知，触控区域TA包括靠近非触控区域NA的边缘区以及被边缘区围绕的中间区，位于触控区域TA的中间区中的第一子电极11和第二子电极21基本上均为规则的图案，例如为菱形、正方形，网格线等。位于触控区域TA的边缘区中的第一子电极11和第二子电极21中的至少一些为不规则的图案，特别是与非触控区NA邻接的第一子电极11和第二子电极21。
如图1和2所示，多个连接部30基本上呈阵列排布。以沿第一方向延伸的一列连接部30为例。该列连接部30包括沿第一方向X依次远离所述非触控区域TA布设的第一连接部301、第二连接部302以及第三连接部303。所述第一连接部301、第二连接部302以及第三连接部303沿第一方向X依次两两相邻。
值得注意的是，这里所说的第一连接部301、第二连接部302以及第三连接部303沿第一方向X依次两两相邻指的是，在该列连接部30中，第一连接部301和第二连接部302为彼此相邻的连接部，两者之间不存在其他连接部，第二连接部302和第三连接部303为彼此相邻的连接部，两者之间不存在其他连接部。在本实施例中，第一连接部301为该列连接部30中最靠近下侧非触控区域NA的连接部。
该列连接部30对应的第一触控电极11包括第一方向X依次远离所述非触控区域NA排布的、依次两两相邻的第一个第一子电极111、第二个第一子电极112 和第三个第一子电极113，第一个第一子电极111邻接于所述非触控区域NA。第一连接部301位于所述第一个第一子电极111和所述第二个第一子电极112之间，且与所述第一个第一子电极111和所述第二个第一子电极112均电连接。第二连接部302位于所述第二个第一子电极112和所述第三个第一子电极113之间，且与所述第二个第一子电极112和所述第三个第一子电极113均电连接。所述第三连接部303位于所述第三个第一子电极113远离所述第二连接部302一侧，且与所述第三个第一子电极113电连接。
如图2所示，第一连接部301在基材100上的正投影的中心与所述第二连接部302在基材100上的正投影的中心之间的距离小于所述第二连接部302在基材100上的正投影的中心与所述第三连接部303在基材100上的正投影的中心之间的距离。
与该列连接部30相邻的多列连接部30以及它们对应第一触控电极10均采用类似的设置。如此，该些第一触控电极10的与非触控区域NA邻接的第一子电极的面积相较于相关技术明显增大，改善了触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，进而实现数字轮盘功能。
图3为相关技术中触控面板的部分平面示意图，图3的结构与图2相对应，如图1和3所示，多个连接部30基本上呈阵列排布。以沿第一方向X延伸的一列连接部30为例。该列连接部30与图2中举例说明的列连接部30相对应。该列连接部30包括沿第一方向X依次远离所述非触控区域TA布设的第一连接部301’、第二连接部302’以及第三连接部303’。所述第一连接部301’、第二连接部302’以及第三连接部303’沿第一方向X依次两两相邻。图3中所示的第一连接部301’、第二连接部302’以及第三连接部303’分别对应图2中所示的第一连接部301、第二连接部302以及第三连接部303。
该列连接部30对应的第一触控电极11包括第一方向X依次远离所述非触控区域排布的、依次两两相邻的第一个第一子电极111’、第二个第一子电极112’和第三个第一子电极113’，第一个第一子电极111’邻接于所述非触控区域NA。第一连接部301’位于所述第一个第一子电极111’和所述第二个第一子电极112’之间，且与所述第一个第一子电极111’和所述第二个第一子电极112’均电连接。第二连接部302’位于所述第二个第一子电极112’和所述第三个第一子电极113’之间，且与所述第二个第一子电极112’和所述第三个第一子电极113’均电连接。 所述第三连接部303’位于所述第三个第一子电极113’远离所述第二连接部302’一侧，且与所述第三个第一子电极113’电连接。图3中所示的第一个第一子电极111’、第二个第一子电极112’和第三个第一子电极113’分别对应图2中所示的第一个第一子电极111、第二个第一子电极112和第三个第一子电极113。
如图3所示，第一连接部301’在基材100上的正投影的中心与所述第二连接部302’在基材100上的正投影的中心之间的距离等于所述第二连接部302’在基材100上的正投影的中心与所述第三连接部303’在基材100上的正投影的中心之间的距离。图3中，与该列连接部30相邻的多列连接部30以及它们对应第一触控电极10均采用类似的设置。如图3所示，相关技术中，位于触控区域TA与非触控区域NA边界处的第一子电极11的面积很小，其中一些第一子电极11的面积小于等于正常子电极的面积的50％。这里所说正常子电极指的是位于触控区域TA中间区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(后续亦称为正常第一子电极)和/或第二子电极(后续亦称为正常第二子电极)。由于相关技术中，位于触控区域TA与非触控区域NA边界处的一些第一子电极和/或第二子电极面积过小，导致触控区域的边缘区的触控信号强度较小，触控信号与背景噪声信号无法分辨，不能实现数字轮盘功能。
为了方便理解，图2所示的实施例提供的触控面板可以相当于在图3所示的相关技术的基础上，将最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动，与该行连接部30中的各连接部30相连接的第一子电极和第二子电极的形状相应调整，使得位于触控区域TA与非触控区域NA边界处的第一子电极和/或第二子电极的面积具有较好的相对均一性，避免面积过小，改善触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，实现数字轮盘功能。
最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动的距离小于或等于正常第一子电极沿第一方向X的最大跨度或任意边上两点之间最大长度(后续简称为沿第一方向X的最大长度)的1/2。也就是说，如图2所示，第一连接部301在基材100上的正投影的中心与所述第二连接部302在基材100上的正投影的中心之间的距离与所述第二连接部302在基材100上的正投影的中心与所述第三连接部303在基材100上的正投影的中心之间的距离的差小于或等于所述第二连接部302与所述三连接部303之间的所述第三 个第一子电极113沿第一方向X上的最大长度(即第三个第一子电极113沿第一方向的对角线的长度)的1/2。在一些实施例中，最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动的距离小于或等于正常第一子电极沿第一方向X的最大跨度或任意边上两点之间最大长度的大约1/2。此处的大约1/2中的大约指的是不严格限定界限，允许工艺和误差测量范围内的数值。
此时，即可以使得位于触控区域TA与非触控区域NA边界处的第一子电极和/或第二子电极的面积具有较好的相对均一性，又可以避免任意两相邻的连接部30之间距离过小。触控面板中连接部30通常包括金属架桥，金属架桥因其材料特性就决定了其光透过率几乎为零，若两相邻的连接部30之间距离过小，该两相邻连接部的两金属架桥在人眼视觉上就相连在了一起。当触控面板引用至包括触控屏幕的电子装置中时，屏幕上将会出现黑点轮廓，这将严重影响屏幕的画面展示。
为了清楚体现图2中最靠近下侧非触控区域NA的一行连接部30相对于图3中所述的相关技术的位置变化，图11同时示出了图2和图3中的结构，如图11所示，最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动的距离为d1，正常第一子电极，例如为第三个第一子电极沿第一方向X的最大跨度或任意边上两点之间最大长度为L1。
在一些实施例中，对于最靠近下侧非触控区域NA的一行连接部30，在移动前，如图3和11所示，该行连接部30中各连接部30在基材100上的正投影的中心均位于沿第二方向Y延伸的直线上。在移动后，如图2和图11所示，该行连接部30中各连接部30在基材100上的正投影的中心亦均位于沿第二方向Y延伸的直线上。也就是说，该行连接部在移动时整体平移。
在一些实施例中，移动后的连接部30与第一方向和第二方向上的连接部均在一条直线上，且与此连接部最相邻的四个电极的面积均小于正常第一子电极的面积。
在一些实施例中，最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动的距离等于正常第一子电极沿第一方向X的最大长度的1/4。也就是说，如图2所示，第一连接部301在基材100上的正投影的中心与所述第二连接部302在基材100上的正投影的中心之间的距离与所述第 二连接部302在基材100上的正投影的中心与所述第三连接部303在基材100上的正投影的中心之间的距离的差小于或等于所述第二连接部302与所述三连接部303之间的所述第三个第一子电极113沿第一方向上的最大长度的1/4。
在一些实施例中，最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动的距离小于或等于正常第一子电极沿第一方向X的最大跨度或任意边上两点之间最大长度的大约1/4。此处的大约1/4中的大约指的是不严格限定界限，允许工艺和误差测量范围内的数值。
在一些实施例中，如图2所示，与所述第一连接部301相邻的所述第一个第一子电极111和所述第二个第一子电极112的面积均占到所述第二连接部302与所述第三连接部303之间的第三个第一子电极113的面积的大约50％～100％，其中第三个第一子电极113为一正常第一子电极。与所述第一连接部301相邻的两个第二子电极21的面积均占到与所述第三连接部303相邻且电连接的两个第二子电极21中的更加远离所述非触控区域的一个(为一正常第二子电极)的面积的大约50％～100％。特别是在触控区域和非触控区域之间的边界为弧形时，与所述第三连接部303相邻且电连接的两个第二子电极21往往与非触控区域的距离是不同的，更远离非触控区域的那个第二子电极21通常会更靠近触控区域的中心位置(当触控区域为圆形时)。此处的大约指的是不严格限定界限，允许工艺和误差测量范围内的数值。
在相关技术中如图3所示，编号为1，2，3，4的第一子电极的面积均等于正常第一子电极的面积。编号为5，6，7，8的第一子电极的面积明显小于正常第一子电极的面积，尤其是编号为5和8第一子电极的面积过小，小于正常第一子电极的面积的50％。导致触控区域的边缘区的触控信号强度较小，触控信号与背景噪声信号无法分辨，不能实现数字轮盘功能。触控面板中的某一点的触控信号强度与在该点处的模拟探测电容数值变化量正相关，模拟探测电容数值变化量可以表示手指触碰该点时该点处的电容信号变化量。在图3中，M点处的模拟探测电容数值变化量为0.0805pF，N点处的探测电容数值变化量为0.0348pF。
而在本公开的一些实施例中，如图2所示，编号为1-8的第一子电极的面积均为正常第一子电极的面积的50％～100％。以最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动的距离等于正常第一子电极沿第一方向X的最大长度的1/4的情况为例。具体地，编号为1，2，3，4的 第一子电极的面积均大约等于正常第一子电极的面积的75％。编号为5，6，7，8的第一子电极的面积均大于或等于正常第一子电极的面积的50％，其中编号为6，7的第一子电极的面积均约等于正常第一子电极的面积的77.3％。同时编号为22，23，24的第二子电极的面积均大于正常第二子电极的面积的75％，例如，编号为22，24第二子电极的面积大约为正常第二子电极的面积的85.4％，编号为23第二子电极的面积大约为正常第二子电极的面积的86.4％。在图2中，M点处的模拟探测电容数值变化量为0.1323pF，N点处的探测电容数值变化量为0.0772pF。
相较于相关技术，尽管上述实施例压缩了编号为1，2，3，4的第一子电极的面积，但通过位于触控区域的边缘区的第一子电极和第二子电极的面积的调整，改善了触控区域的边缘区中第一子电极和第二子电极的面积均一性，并且M点处的模拟探测电容数值变化量增加了1.64倍，N点的模拟探测电容数值变化量增加了2.21倍。由此，改善了触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，进而实现数字轮盘功能。
如上所述，图2所示的实施例提供的触控面板可以相当于在图3所示的相关技术的基础上，将最靠近下侧非触控区域NA的一行连接部30整体沿第一方向X远离非触控区域NA移动，该行连接部30中的各连接部沿第一方向X远离非触控区域NA移动的距离相等。本领域技术人员可以理解的是，在一些实施例中，该行连接部30中的各连接部30沿第一方向X远离非触控区域NA移动的距离可以不相等，或者在一些实施例中，该行连接部30中的各连接部30沿与第一方向X呈一定夹角的方向远离非触控区域NA移动，只要能到达到改善了触控区域的边缘区中第一子电极和第二子电极的面积均一性的效果即可。
图4为图1中B区域的平面示意图，图4示意性地示出了触控面板周边区域的平面结构，图4仅示出了触控区域TA的一部分，省略了非触控区域NA。结合图1和图4可知，触控区域TA包括靠近非触控区域NA的边缘区以及被边缘区围绕的中间区，位于触控区域TA的中间区中的第一子电极11和第二子电极21基本上均为规则的图案，例如为菱形、正方形、网格线等。位于触控区域TA的边缘区中的第一子电极11和第二子电极21中的至少一些为不规则的图案，特别是与非触控区NA邻接的第一子电极11和第二子电极21。
如图1和4所示，多个连接部30基本上呈阵列排布。以沿第二方向Y延伸 的一行连接部30为例。该行连接部30包括沿第二方向Y依次远离所述非触控区域TA布设的第四连接部304、第五连接部305以及第六连接部306。所述第四连接部304、第五连接部305以及第六连接部306沿第二方向Y依次两两相邻。
值得注意的是，这里所说的第四连接部304、第五连接部305以及第六连接部306沿第二方向Y依次两两相邻指的是，在该行连接部30中，第四连接部304和第五连接部305为彼此相邻的连接部，两者之间不存在其他连接部，第五连接部305和第六连接部306为彼此相邻的连接部，两者之间不存在其他连接部。在本实施例中，第四连接部301为该行连接部30中最靠近右侧非触控区域NA的连接部。
该行连接部30对应的第二触控电极21包括第二方向Y依次远离所述非触控区域NA排布的、依次两两相邻的第一个第二子电极211、第二个第二子电极212和第三个第二子电极213，第一个第二子电极211邻接于所述非触控区域NA。第四连接部304位于所述第一个第二子电极211和所述第二个第二子电极212之间，且与所述第一个第二子电极211和所述第二个第二子电极212均电连接。第五连接部305位于所述第二个第二子电极212和所述第三个第二子电极213之间，且与所述第二个第二子电极212和所述第三个第二子电极213均电连接。所述第六连接部306位于所述第三个第二子电极213远离所述第五连接部305一侧，且与所述第三个第二子电极213电连接。
如图4所示，第四连接部304在基材100上的正投影的中心与所述第五连接部305在基材100上的正投影的中心之间的距离小于所述第五连接部305在基材100上的正投影的中心与所述第六连接部303在基材100上的正投影的中心之间的距离。
与该行连接部30相邻的多行连接部30以及它们对应第二触控电极20均采用类似的设置。如此，该些第二触控电极20的与非触控区域NA邻接的第二子电极的面积相较于相关技术明显增大，改善了触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，进而实现数字轮盘功能。
图5为相关技术中触控面板的部分平面示意图，图5的结构与图4相对应，如图1和5所示，多个连接部30基本上呈阵列排布。以沿第二方向Y延伸的一行连接部30为例。该行连接部30与图4中举例说明的行连接部30相对应。该行连接部30包括沿第二方向Y依次远离所述非触控区域TA布设的第四连接部 304’、第五连接部305’以及第六连接部306’。所述第四连接部304’、第五连接部305’以及第六连接部306’沿第二方向Y依次两两相邻。图3中所示的第四连接部304’、第五连接部305’以及第六连接部306’分别对应图5中所示的第四连接部304、第五连接部305以及第六连接部306。
该行连接部30对应的第二触控电极21包括第二方向Y依次远离所述非触控区域排布的、依次两两相邻的第一个第二子电极211’、第二个第二子电极212’和第三个第二子电极213’，第一个第二子电极211’邻接于所述非触控区域NA。第四连接部304’位于所述第一个第二子电极211’和所述第二个第二子电极212’之间，且与所述第一个第二子电极211’和所述第二个第二子电极212’均电连接。第五连接部305’位于所述第二个第二子电极212’和所述第三个第二子电极213’之间，且与所述第二个第二子电极212’和所述第三个第二子电极213’均电连接。所述第六连接部306’位于所述第三个第二子电极213’远离所述第五连接部305’一侧，且与所述第三个第二子电极213’电连接。图五中所示的第一个第二子电极211’、第二个第二子电极212’和第三个第二子电极213’分别对应图4中所示的第一个第二子电极211、第二个第二子电极212和第三个第二子电极213。
如图5所示，第四连接部304’在基材100上的正投影的中心与所述第五连接部305’在基材100上的正投影的中心之间的距离等于所述第五连接部305’在基材100上的正投影的中心与所述第六连接部306’在基材100上的正投影的中心之间的距离。图5中，与该行连接部30相邻的多行连接部30以及它们对应第二触控电极20均采用类似的设置。如图5所示，相关技术中，位于触控区域TA与非触控区域NA边界处的第二子电极21的面积很小，其中一些第二子电极21的面积小于等于正常子电极的面积的50％。这里所说正常子电极指的是位于触控区域TA中间区的具有规则图案，例如为菱形、正方形等，的第一子电极(后续亦称为正常第一子电极)和/或第二子电极(后续亦称为正常第二子电极)。由于相关技术中，位于触控区域TA与非触控区域NA边界处的一些第一子电极和/或第二子电极面积过小，导致触控区域的边缘区的触控信号强度较小，触控信号与背景噪声信号无法分辨，不能实现数字轮盘功能。
为了方便理解，图4所示的实施例提供的触控面板可以相当于在图5所示的相关技术的基础上，将最靠近右侧非触控区域NA的一列连接部30整体沿第二方向Y远离非触控区域NA移动，与该列连接部30中的各连接部30相连接的第 一子电极和第二子电极的形状相应调整，使得位于触控区域TA与非触控区域NA边界处的第一子电极和/或第二子电极的面积具有较好的相对均一性，避免面积过小，改善触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，实现数字轮盘功能。
最靠近右侧非触控区域NA的一列连接部30整体沿第二方向Y远离非触控区域NA移动的距离小于或等于正常第二子电极沿第二方向Y的最大跨度或任意边上两点之间最大长度(后续简称为沿第二方向Y的最大长度)的1/2。也就是说，如图4所示，第四连接部304在基材100上的正投影的中心与所述第五连接部305在基材100上的正投影的中心之间的距离与所述第五连接部305在基材100上的正投影的中心与所述第六连接部306在基材100上的正投影的中心之间的距离的差小于或等于所述第五连接部305与所述六连接部306之间的所述第三个第二子电极213沿第二方向Y上的长度(即第三个第二子电极213沿第二方向的对角线的长度)的1/2。在一些实施例中，最靠近右侧非触控区域NA的一列连接部30整体沿第二方向Y远离非触控区域NA移动的距离小于或等于正常第二子电极沿第二方向Y的最大跨度或任意边上两点之间最大长度的大约1/2。此处的大约1/2中的大约指的是不严格限定界限，允许工艺和误差测量范围内的数值。
此时，即可以使得位于触控区域TA与非触控区域NA边界处的第一子电极和/或第二子电极的面积具有较好的相对均一性，又可以避免任意两相邻的连接部30之间距离过小。触控面板中连接部30通常包括金属架桥，金属架桥因其材料特性就决定了其光透过率几乎为零，若两相邻的连接部30之间距离过小，该两相邻连接部的两金属架桥在人眼视觉上就相连在了一起。当触控面板引用至包括触控屏幕的电子装置中时，屏幕上将会出现黑点轮廓，这将严重影响屏幕的画面展示。
为了清楚体现图4中最靠近下侧非触控区域NA的一行连接部30相对于图5中所述的相关技术的位置变化，图12同时示出了图4和图5中的结构，如图12所示，最靠近右侧非触控区域NA的一列连接部30整体沿第二方向Y远离非触控区域NA移动的距离为d2，正常第二子电极，例如为第三个第二子电极沿第二方向Y的最大跨度或任意边上两点之间最大长度为L2。
在一些实施例中，对于最靠近右侧非触控区域NA的一列连接部30，在移动 前，如图5和12所示，该列连接部30中各连接部30在基材100上的正投影的中心均位于沿第一方向X延伸的直线上。在移动后，如图4和图11所示，该列连接部30中各连接部30在基材100上的正投影的中心亦均位于沿第一方向X延伸的直线上。也就是说，该列连接部在移动时整体平移。
在一些实施例中，移动后的连接部30与第一方向和第二方向上的连接部均在一条直线上，且与此连接部最相邻的四个电极的面积均小于正常第二子电极的面积。
在一些实施例中，最靠近右侧非触控区域NA的一行连接部30整体沿第二方向Y远离非触控区域NA移动的距离等于正常第二子电极沿第二方向Y的最大长度的1/4。也就是说，如图4所示，第四连接部304在基材100上的正投影的中心与所述第五连接部305在基材100上的正投影的中心之间的距离与所述第五连接部305在基材100上的正投影的中心与所述第六连接部306在基材100上的正投影的中心之间的距离的差小于或等于所述第五连接部305与所述六连接部306之间的所述第三个第二子电极213沿第二方向Y上的最大长度的1/4。
在一些实施例中，如图4所示，与所述第四连接部304相邻的所述第一个第二子电极211和所述第二个第二子电极为212的面积均占到所述第五连接部305与所述六连接部306之间的第三个第二子电极213的面积的50％～100％，其中第三个第二子电极213为一正常第二子电极。与所述第四连接部304相邻的两个第一子电极11的面积均占到与所述第六连接部306相邻且电连接的两个第一子电极11中的更加远离所述非触控区域的一个(为一正常第一子电极)的面积的50％～100％。特别是在触控区域和非触控区域之间的边界为弧形时，与所述第六连接部303相邻且电连接的两个第一子电极11往往与非触控区域的距离是不同的，更远离非触控区域的那个第一子电极11通常会更靠近触控区域的中心位置(当触控区域为圆形时)。
如上所述，图4所示的实施例提供的触控面板可以相当于在图5所示的相关技术的基础上，将最靠近右侧非触控区域NA的一列连接部30整体沿第二方向Y远离非触控区域NA移动，该列连接部30中的各连接部沿第二方向Y远离非触控区域NA移动的距离相等。本领域技术人员可以理解的是，在一些实施例中，该列连接部30中的各连接部30沿第二方向Y远离非触控区域NA移动的距离可以不相等，或者在一些实施例中，该列连接部30中的各连接部30沿与第二方向 Y呈一定夹角的方向远离非触控区域NA移动，只要能到达到改善了触控区域的边缘区中第一子电极和第二子电极的面积均一性的效果即可。
图1中C区域的具体结构与B区域的具体结构类似，两者相对于触控面板沿第一方向X的轴线大致镜像对称，在此不再赘述。图1中D区域的具体结构与A区域的具体结构类似，两者相对于触控面板沿第二方向Y的轴线大致镜像对称，在此不再赘述。
本实施例中的方案相较于相关技术，通过位于触控区域的边缘区的第一子电极和第二子电极的面积的调整，改善了触控区域的边缘区中第一子电极和第二子电极的面积均一性，改善了触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，进而实现数字轮盘功能。
在上述实施例中，触控区域TA与非触控区域TA的边界为圆形。本领域技术人员可以理解的是在其他实施例中，触控区域TA与非触控区域TA的边界为圆形还可以为其他形状，例如为椭圆形。更进一步地，只要触控区域TA与非触控区域TA的边界的至少一部分弧形或使得位于触控区域TA与非触控区域TA的边界处的第一子电极和/或第二子电极面积均一性差即可采用本公开的设计思路，将临近触控区域TA与非触控区域TA的边界的至少一个连接部沿远离非触控区域TA的方向移动，进而调整与其相连接的触控第一子电极和/或第二子电极面积，改善触控区域TA与非触控区域TA的边界处的第一子电极和/或第二子电极面积均一性，改善触控区域和非触控区域的边界处，即触控区域的边缘区的触控效果，进而实现数字轮盘功能。
图6为图1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，其中两个第一子电极均为正常第一子电极，两个第二子电极，均为正常第二子电极。
如图6所示，连接部30包括第一连接子部31和第二连接子部32。第一连接子部31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11。第二连接子部32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31和第二连接子部32相互电绝缘，它们之间具有绝缘层。在本文中，上述连接部30可以看成是第一连接子部31和第二连接子部32的层叠结构所在的规则区域。图7为图6中的结构沿线E-E’的截面示意图。如图6和图7所示，第一子电极11和第二子电极21位于同一电极层，记为第一电极层51， 该第一电极层51设置在基材100上。第二连接子部32可以与沿第二方向Y相邻的两个第二子电极21为一体结构，即第二连接子部32亦位于第一电极层51中，第二连接子部32与包括第一子电极11的第一触控电极10和包括第二子电极21的第二触控电极20同层设置。第一连接子部31位于第二电极层52。第二电极层52位于第一电极层51远离基材100一侧。且第一电极层51和第二电极层52之间设置有绝缘层40。绝缘层40中设置有过孔41，第一连接子部31的一个端部通过过孔41与一个第一子电极11电连接，第一连接子部31的另一个端部通过过孔41与另一个第一子电极11电连接，使得两个第一子电极11通过桥接的方式电连接。图8为图1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，其中两个第一子电极均为正常第一子电极，两个第二子电极，均为正常第二子电极。
如图8所示，连接部30包括第一连接子部31和第二连接子部32。第一连接子部31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11。第二连接子部32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31和第二连接子部32相互电绝缘，它们之间具有绝缘层。
图9为图8中的结构沿线M-M’的截面示意图。如图8和图9所示，第一子电极11和第二子电极21位于同一电极层，记为第一电极层51，该第一电极层51设置在基材100上。第一连接子部31可以与沿第一方向X相邻的两个第一子电极11为一体结构，即第一连接子部31亦位于第一电极层51中，第一连接子部31与包括第一子电极11的第一触控电极10和包括第二子电极的第二触控电极20同层设置。第二连接子部32位于第二电极层52。第二电极层52位于第一电极层51远离基材100一侧。且第一电极层51和第二电极层52之间设置有绝缘层40。绝缘层40中设置有过孔42，第二连接子部32的一个端部通过过孔42与一个第二子电极21电连接，第二连接子部31的另一个端部通过过孔42与另一个第二子电极21电连接，使得两个第二子电极21通过桥接的方式电连接。
本文中所说的连接部30是指由图6或图8中虚线框表示的部分，包括第一连接子部31和第二连接子部32构成的层叠结构，连接部30在基材100上的正投影的中心由如图6或图8中的S表示，即为图6或图8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30的所处位置。本领域技术人员可以理解的是在图1-5中，为了方便绘图，仅以“+”来表示连接部30，以“+” 的中心表示连接部30在基材100上的正投影的中心S。
在一些实施例中，连接部30中的第一连接子部31可以为一条或更多条，连接部30中的第二连接子部32亦可以为一条或更多条。图6和图8中，仅给出了连接部30具有一条第一连接子部31和一条第二连接子部32的示例。
图10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10所示，连接部30具有两条第一连接子部31和一条第二连接子部32。图10中所示的结构相较于图6中所示的结构增加了一条第一连接子部31，第一连接子部31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10和图15所示，所述连接部30为虚线框所示的长方形。在一些实施例中，所述连接部30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30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30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31和/或第二连接子部32可以为直条状(如图6，8所示)、弯折条状(如图10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。
在一些实施例中，第一连接子部31沿第一方向X的最大长度等于一正常第一子电极沿第一方向X上的最大长度的大约1/4，正常第一子电极例如为图2中所示的第二连接部302与所述第三连接部303之间的第三个第一子电极113。第二连接子部31沿第一方向X的最大长度等于一正常第一子电极沿第一方向X上的最大长度的大约1/4，正常第二子电极例如为图5中所示的第五连接部305与所述第三连接部306之间的第三个第二子电极213。大约指的是不严格限定界限，允许工艺和误差测量范围内的数值。
在一些实施例中，正常第一子电极沿第一方向X上的最大长度与正常第二子电极沿第二方向Y上的最大长度可以相等，也可以不相等。
在前述实施例中，均以相邻的第一子电极11和第二子电极21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11和第二子电极21的边界可以为其他形状，例如为折线状。以下以图2中的标号为6的第一子电极和标号为22的第二子电极21的边界来举例说明。
图13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6的第一子电极11和标号为22的第二子电极21的一部分以及它们之间的边界。如图13所示，第一子电极11和第二子电极21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11和第二子电极21之间的边界呈直线状(图13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11和第二子电极21的尺寸，如图2和图13所示，可以进一步增大标号为6的第一子电极11的尺寸，缩小标号为22的第二子电极21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11和第二子电极21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14为图13中区域Z的放大示意图，如图14所示，标号为6的第一子电极11和标号为22的第二子电极21之间的边界60包括位于第一子电极11和第二子电极21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11，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21。边界60还包括位于第一子电极11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21之间的第三间隔65。第一间隔61使得第一子电极11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21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11和第二子电极21采用相同材料同层设置。该种设置可以使得第一子电极11和第二子电极21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。
本领域技术人员可以理解的是，任意相邻的第一子电极11和第二子电极21之间的边界均可以采用上述类似的设置。
图15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15主要示出了一个连接部30的具体结构及该连接部周边的结构。连接部30为图15中虚线框表示的部分，包括第一连接子部31和第二连接子部32构成的层叠结构，为所述层叠结构所在的规则区域。与图10中示出的连接部30类似，图15中的连接部30包括两个第一连接子部31(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32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15所示，连接部30连接位于上侧的第一子电极11和位于下侧的第一子电极11，并且连接部30连接位于左侧的第二子电极21和位于右侧的第二子电极21。任意相邻的第一子电极和第二子电极21之间的边界60为折线状，类似图13中所示出的边界。图15中仅示出了边界60靠近连接部30的一部分。

在一些实施例中，第一连接子部31在第一方向X上的最大长度与第二连接子部32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32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°。
