由于BM材质中含有碳元素，具有一定的导电性，因而形成有BM的区域比触控面板的可视区域(View area)更易发生静电击穿(Electro-Static discharge；简称：ESD)现象，使得在形成有BM的区域(简称：BM区)中，ITO图形中的触摸感应线、触摸驱动线与其他的图形单元之间更容易发生短路，从而影响触摸感应线和触摸驱动线之间电容的大小，进而影响触控面板的触摸效果。

在一些实施例中，所述透明导电图形还包括翅膀线，所述翅膀线为从第二主触控线上延伸出的，且设置方向与所述第二主触控线的设 置方向不同的从触控线，所述第二主触控线为所述多条触摸驱动线和所述多条触摸感应线中的一个，所述多个空置块包括所述重叠区域中与所述第二主触控线、所述翅膀线均相邻的第二空置块，以及所述重叠区域中与所述第二主触控线不相邻且与所述翅膀线均相邻的第三空置块。围绕所述第二空置块的间隙包括：所述第二空置块分别与所述第二主触控线、所述翅膀线之间的间隙、所述第二空置块与相邻的空置块之间的第三间隙和第四间隙；围绕所述第三空置块的间隙包括：所述第三空置块与所述翅膀线之间的间隙和所述第三空置块与相邻的空置块之间的第五间隙；所述第三间隙的延伸方向平行所述第二主触控线的设置方向，所述第三间隙从所述翅膀线开始直至延伸出所述黑矩阵的内边界第二距离终止，所述第四间隙的延伸方向平行所述黑矩阵的内边界，所述第五间隙的延伸方向平行所述翅膀线的设置方向，所述第二距离与所述可视区域中的图形单元的间隙宽度相等。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施例作进一步地详细描述。
如图1-1所示，图1-1是本发明实施例提供的一种触控面板10的 结构示意图，触控面板10包括衬底基板(图1-1中未标示)，该衬底基板可以为透明玻璃。在衬底基板上形成有黑矩阵101，黑矩阵101位于衬底基板边缘的环形区域(图1-1中的阴影区域)。形成有黑矩阵101的衬底基板上形成有透明导电图形102(图1-1中虚线框中的图形)，透明导电图形102和所述环形区域中的黑矩阵存在重叠区域W。为了更为清晰地进行说明，如图1-2所示，图1-2为图1-1中未对黑矩阵进行阴影标示的触控面板的结构示意图，透明导电图形102包括：多条横向设置的触摸驱动线1021和多条纵向设置的触摸感应线1022，以及多个空置块1023，多条横向设置的触摸驱动线1021和多条纵向设置的触摸感应线1022相互绝缘，每个空置块1023可形成所述透明导电图形中的一个独立图形单元。这些多个空置块可用于调节触摸感应线和触摸驱动线之间的互电容，改善触控面板的可视区域的光学效果。
在本发明实施例中，触摸驱动线1021和触摸感应线1022可以是通过一次构图工艺形成的同层设置的图形，通过设置间隙使两者绝缘。
进一步的，透明导电图形102还可包括多个导电桥1024，该多个导电桥用于电连接该多个横向设置的触摸驱动线。
位于重叠区域中的空置块的分布密度大于位于触控面板的可视区域中的空置块的分布密度。本发明实施例中，空置块的分布密度指的是在单位面积内空置块分布的紧密程度。单位面积内空置块的个数越多，其分布密度越大。
综上所述，对于本发明实施例提供的触控面板，透明导电图形中位于重叠区域中的空置块的分布密度大于位于可视区域中的空置块的分布密度，由于重叠区域中的空置块的分布密度较大，也即是，在单位面积中，重叠区域中的空置块的个数较多，重叠区域中的每个空置块的面积相对较小，在触摸驱动线或触摸感应线与空置块发生短路时，由于黑矩阵区中的空置块的面积较小，对触摸驱动线和触摸感应线之间的互电容的大小的影响较弱，从而有效减少了对触控面板的触摸效果的影响。
进一步的，多条横向设置的触摸驱动线和多条纵向设置的触摸感应线可形成多个十字结构M。如图2所示，每个十字结构M以及位于十字结构M四角的空置区N(该空置区类似于矩形区，图2以矩形虚线框示意性标出)内的多个空置块1023组成一个触控单元。示例的， 透明导电图形102可以由锡铟氧化物(ITO)制成。在一些实施中，透明导电图形102为轴对称图形，且存在两个互相垂直的对称轴。如图1-2所示，该透明导电图形102近似于矩形，这样可以保证触控面板的光学性能的一致性。
如图1-2所示，空置区中位于重叠区域中的空置块的分布密度均大于位于可视区域的空置块的分布密度。例如，图1-2中位于重叠区域W中的部分空置区N1中的空置块的分布密度大于位于可视区域的空置区N2的空置块的分布密度，本发明实施例中，可视区域也即是透明导电图形上除重叠区域之外的区域。
实际应用中，可能的是一个空置区的部分或全部处于重叠区域中，图1-1和图1-2是以空置区的一部分位于重叠区域中为例进行说明的。并且，透明导电图形102中的触摸驱动线和触摸感应线的个数是根据触控面板的尺寸来适应性设置的，图1-1和图1-2只是以3个触摸驱动线和3个触摸感应线为例进行说明。
在本发明实施例中，重叠区域中的空置块的分布规律通常是空置块的面积正相关于该空置块与主触控线的距离，也即是，空置块越靠近主触控线，其面积越小。该主触控线可以为触摸驱动线或触摸感应线。在一些实施例中，该重叠区域中的多个空置块的面积从远离到靠近主触控线依次减小。由于靠近主触控线的空置块的面积较小，当主触控线与该空置块发生短路时，对触摸驱动线和触摸感应线之间的电容的大小的影响较弱，从而有效减少了对触控面板的触摸效果的影响。
在一些实施例中，由于透明导电图形的空置块的形状各异，通常是不规则形状，不一定能保证重叠区域中的多个空置块的面积从远离到靠近触控线依次减小。因此，此时保证重叠区域中靠近触控线的空置块的面积小于预设面积即可，该预设面积为在该空置块与触控线短路时，对触摸驱动线和触摸感应线之间的电容的大小的影响小于预设程度时对应的面积。
图2至图10均为本发明实施例提供的触控单元的结构示意图，图2为其全部区域位于图1-1中可视区域内的触控单元L1的结构示意图，由图1-1可以看出，其全部区域位于可视区域内的触控单元的结构相同，且与触控单元L1的结构相同；图3至图6分别为存在部分区域位于图1所示的重叠区域的上边缘、下边缘、左边缘和右边缘的触控单元L2、 L3、L4和L5的结构示意图；图7至图10分别为存在部分区域位于图1所示的重叠区域的左上角、右上角、左下角和右下角的触控单元L6、L7、L8和L9的结构示意图。
透明触控电极102通常可以分为两类，带有翅膀(wing)线的透明触控电极和不带有翅膀线的透明触控电极。图1-1至图10中的透明触控电极102均为带有翅膀线的透明触控电极，由图1-1至图10可以看出，本发明实施例中的透明触控电极102还可以包括翅膀(wing)线，该翅膀线为从某一主触控线上延伸出的，且设置方向与该某一主触控线的设置方向不同的从触控线，该某一主触控线为触摸驱动线和触摸感应线的一个。设置有翅膀线的透明触控电极102的整体电阻较小，触控单元的衔接更顺畅。
图11为本发明实施例提供的不带有翅膀线的透明触控电极的触控单元的局部示意图。如图11所示，触控面板的透明导电图形包括重叠区域中与第一主触控线相邻的第一空置块，第一主触控线为触摸驱动线和触摸感应线中的一个，围绕第一空置块的间隙包括：第一空置块与第一主触控线之间的间隙、第一空置块与相邻的空置块之间的第一间隙以及第二间隙。该相邻的空置块可以为一个或多个。
示例的，假设图11中第一主触控线为触摸驱动线Tx，第一空置块为A，围绕第一空置块A的间隙包括：第一空置块A与第一主触控线Tx之间的间隙a1、第一空置块A与相邻的空置块之间的第一间隙a2以及第二间隙a3。
示例的，假设图11中第一主触控线为触摸感应线Rx，第一空置块为B，围绕第一空置块B的间隙包括：第一空置块B与第一主触控线Rx之间的间隙b1、第一空置块B与相邻的空置块之间的第一间隙b2以及第二间隙b3。
第一间隙的延伸方向平行第一主触控线的设置方向，第一间隙从透明导电图形的边界延伸出黑矩阵的内边界P第一距离F，第二间隙的延伸方向平行黑矩阵的内边界P，该第一距离F与可视区域中的图形单元的间隙宽度相等，通常为30um。这样可以保证可视区域的光学均匀性并且减少ESD的发生。该第二间隙的两个边界分别和黑矩阵的内边界P存在一定距离，其中靠近可视区域的边界与黑矩阵的内边界P的距离为上述第一距离F，另一个边界与该黑矩阵的内边界P的距离可以 为30um至90um，优选为30um。
图12为本发明实施例提供的带有翅膀线的透明触控电极的触控单元的局部示意图。如图12所示，透明导电图形还包括翅膀线Tw，翅膀线为从第二主触控线上延伸出的，且设置方向与第二主触控线的设置方向不同的触控线，第二主触控线为触摸驱动线和触摸感应线的一个。
透明导电图形可包括重叠区域中与第二主触控线、翅膀线均相邻的第二空置块，以及重叠区域中与第二主触控线不相邻且与翅膀线均相邻的第三空置块。
围绕第二空置块的间隙包括：第二空置块分别与第二主触控线、翅膀线之间的间隙、第二空置块与相邻的空置块之间的第三间隙以及第四间隙；围绕第三空置块的间隙包括：第三空置块与翅膀线之间的间隙和第三空置块与相邻的空置块之间的第五间隙。
示例的，假设在图12中第二主触控线为触摸驱动线Tx，第二空置块为C，第三空置块为D，翅膀线为Tw，围绕第二空置块C的间隙包括：第二空置块C分别与第二主触控线Tx、翅膀线Tw之间的间隙c1、第二空置块C与相邻的空置块之间的第三间隙c2以及第四间隙c3；围绕第三空置块D的间隙包括：第三空置块D与翅膀线Tw之间的间隙d1和第三空置块D与相邻的空置块之间的第五间隙d2。
第三间隙的延伸方向平行第二主触控线Tx的设置方向，第三间隙从翅膀线开始，直至延伸出黑矩阵的内边界P第二距离F终止，第四间隙的延伸方向平行黑矩阵的内边界，第五间隙的延伸方向平行翅膀线的设置方向，该第二距离F与可视区域中的图形单元的间隙宽度相等，通常为30um。这样可以保证可视区域的光学均匀性并且减少ESD的发生。该第四间隙c3的两个边界分别和黑矩阵的内边界P存在一定距离，其中靠近可视区域的边界与黑矩阵的内边界的距离为上述第二距离F，另一个边界与该黑矩阵的内边界的距离可以为30um至90um，优选的为30um。
需要说明的是，在一些实施例中，对于重叠区域中与第二主触控线不相邻且与翅膀线均相邻的第三空置块D，围绕其的间隙也可以不包括与翅膀线的设置方向平行的间隙，只要保证该第三空置块D的面积较小即可，例如，图12中，第三空置块也可以为E，则第三空置块 E与翅膀线Tw之间存在间隙e1和第三空置块E与相邻的空置块之间存在第五间隙e2，该第五间隙e2与翅膀线的设置方向不平行。
进一步的，在带有翅膀线的透明触控电极的触控单元中，如果有的触控单元的空置块仅与触摸驱动线或触摸感应线相邻，该空置块的结构可以参考图11所示的第一空置块A的结构。本发明实施例对此不作赘述。
采用图11和图12所示的空置块的构图方式来形成透明导电图形，可以保证与主触控线的相邻的空置块的面积较小，使得对触摸驱动线和触摸感应线之间电容的大小的影响小于预设程度。并且，只需在构图工艺中将掩膜版的透光区域或不透光区域的形状进行调整，就可以得到这样的透明导电图形，制作工艺较为简便。
进一步的，在一些实施例中，在存在翅膀线的情况下，重叠区域中的空置块的分布规律可以包括空置块的面积正相关于该空置块与翅膀线的距离，也即是，空置块越靠近翅膀线，其面积越小。
如图13所示，图13是一种传统的触控面板20的结构示意图(为了图13的清晰，未对黑矩阵进行阴影标示)，触控面板20包括：衬底基板；在衬底基板上形成有黑矩阵，黑矩阵位于衬底基板边缘的环形区域；形成有黑矩阵的衬底基板上形成有透明导电图形201，透明导电图形201的外边缘和黑矩阵的内边缘之间存在重叠区域，透明导电图形201包括：多条横向设置的触摸驱动线触摸驱动线和多条纵向设置的触摸感应线触摸感应线，以及多个空置块，多条横向设置的触摸驱动线和多条纵向设置的触摸感应线相互绝缘，且形成多个十字结构。每个十字结构以及位于十字结构四角的空置区内的多个空置块组成一个触控单元；透明导电图形201中每个触控单元L0的结构相同，相关技术中，通常将触控单元称为像素，图13的透明导电图形201实际上是由多个相同的像素形成的像素阵列。
因此，将图1-1、图1-2或图3至图10中提供的触控单元与图13提供的触控单元进行比较，可以明显看出，在本发明实施例提供的触控面板10中，黑矩阵与透明导电图形的重叠区域中空置块的分布密度明显大于传统的触控面板20中空置块的分布密度。也即是，在单位面积中，重叠区域中的空置块的个数较多，每个空置块的面积相对较小。在触摸驱动线或触摸感应线与空置块发生短路时，由于黑矩阵区中空 置块的面积较小，对触摸驱动线和触摸感应线之间的电容的大小的影响较弱，从而有效减少了对触控面板的触摸效果的影响。并且，本发明实施例中，改变的是透明导电图形的非显示区域中的空置块的结构，不影响其可视区域的显示。
在传统的触控面板20中，为了改善可视区域的光学效果，可视区域中相邻的各个图形单元的间隙宽度通常为30um(微米)，为了保证触控面板整体结构的均一性，透明导电图形上所有的图形单元的间隙宽度均设置为固定的宽度，也即是30um。本发明实施例中，图形单元可以为构成透明导电图形的最小独立图形，如空置块、触摸驱动线等。
但是，发明人经过多次的实验证实，在透明导电图形和黑矩阵的重叠区域中，两个相邻的图形单元的间隙宽度越大，产生短路的概率越低，因此，在本发明实施例中，位于该重叠区域中的任意两个相邻的图形单元的间隙宽度可以大于30um。这样会有效降低重叠区域短路的概率。
但是，当黑矩阵区内图形单元的间隙宽度增大时，单个触控单元的节点互容值会增大，当间隙宽度过大时(例如大于100um)，节点电容值的增大过多，这样黑矩阵区的节点电容值普遍比可视区域的节点电容值大很多，导致透明导电图形的均匀性差，影响触控面板边缘区域的触摸性能。与触摸驱动线、触摸感应线分别连接的驱动集成电路(英文：Integrated Circuit；简称：IC)芯片所能支持的间隙宽度的上限通常为100um(也即是，在间隙宽度为100um以内时，节点电容值在驱动IC芯片的可接受范围内，此时对触控面板边缘区域的触摸性能影响不大)，为了保证驱动IC芯片的有效驱动，在一些实施例中，如图14所示，本发明实施例所提供的触控面板10中，重叠区域中的任意两个相邻的图形单元的间隙宽度D1为100um。可视区域的间隙宽度D2依然可以为30um。
此外，导体表面有电荷堆积时，电荷密度与导体表面的形状有关，电荷密度在平缓的部位小，在尖的部位最大。因此，导体的尖端容易聚集电荷，当电荷密度达到一定的量值后，电荷产生的电场会很大，就容易会出现尖端放电现象。
本发明实施例中，为了避免尖端放电现象的产生，透明导电图形中任一图形单元的边角为圆角，而圆角相对于尖锐的锐角，其曲率较 小，实现图形的平滑过渡，能够减少电荷聚集，避免尖端放电现象的产生。
综上所述，对于本发明实施例提供的触控面板，透明导电图形中位于重叠区域中的空置块的分布密度大于位于可视区域中的空置块的分布密度，由于位于重叠区域W中的空置块的分布密度较大，也即是，在单位面积中，重叠区域中的空置块的个数较多，重叠区域中的每个空置块的面积相对较小，在触摸驱动线或触摸感应线与空置块发生短路时，由于黑矩阵区内的空置块的面积较小，对触摸驱动线和触摸感应线之间的电容的大小的影响较弱，从而有效减少了对触控面板的触摸效果的影响。
本发明的另外的实施例提供一种触控面板的制造方法，用于制造本发明上述实施例提供的触控面板10，如图15所示，该制造方法包括：
步骤301、在衬底基板上形成黑矩阵，该黑矩阵位于衬底基板边缘的环形区域。
示例的，可以通过沉积或涂覆工艺在衬底基板上形成黑矩阵层，再对该黑矩阵层通过一次构图工艺处理得到所需要的黑矩阵一次构图工艺可以包括光刻胶涂覆、曝光、显影、刻蚀和光刻胶剥离等工艺。形成有黑矩阵101的衬底基板103的截面视图如图16所示，俯视图如图17所示。
步骤302、在形成有黑矩阵的衬底基板上形成透明导电图形，透明导电图形的外边缘和黑矩阵的内边缘之间存在重叠区域，透明导电图形包括：多条横向设置的触摸驱动线触摸驱动线和多条纵向设置的触摸感应线触摸感应线，以及多个空置块，多条横向设置的触摸驱动线和多条纵向设置的触摸感应线相互绝缘。
示例的，可以通过沉积或涂覆工艺在衬底基板上形成透明导电层，再对该透明导电层通过一次构图工艺处理得到透明导电图形。一次构图工艺可以包括光刻胶涂覆、曝光、显影、刻蚀和光刻胶剥离等工艺。
在步骤302之前或步骤302之后，该方法还可包括：在衬底基板上形成多个导电桥，该多个导电桥用于连接该多个横向设置的触摸驱动线，该多个横向设置的触摸驱动线能够通过该导电桥进行信号的传输。在本发明的该实施例中，可以通过5次构图工艺，也称5mask(中文：掩膜)，或者6次构图工艺，也称6mask，形成该触控面板。在通 过5次构图工艺形成该触控面板的场景中，该导电桥由金属(Metal)材质形成；在通过6次构图工艺形成该触控面板的场景中，该导电桥由ITO材质形成，与透明导电图形的形成材质相同。
形成有导电桥和透明导电层的衬底基板俯视图可以如图1-1或图1-2所示。
位于重叠区域中的空置块的分布密度大于位于可视区域中的空置块的分布密度。多条横向设置的触摸驱动线和多条纵向设置的触摸感应线形成多个十字结构，每个十字结构以及位于十字结构四角的空置区内的多个空置块组成一个触控单元。每个位于重叠区域中的第一空置区中的空置块的分布密度均大于位于可视区域的第二空置区中空置块的分布密度，第一空置区和第二空置区在不同触控单元中的相对位置相同。
在一些实施例中，位于重叠区域中的任意两个相邻的图形单元的间隙宽度大于30um。
在一些实施例中，重叠区域中的任意两个相邻的图形单元的间隙宽度为100um。
在一些实施例中，透明导电图形中任一图形单元的边角为圆角。
可在一些实施例中，透明导电图形为轴对称图形，且存在两个互相垂直的对称轴。
本发明实施例中触控面板的制造方法的具体解释可以参考上述装置实施例中的相应描述，本发明实施例对此不再赘述。
综上所述，利用本发明实施例提供的触控面板的制造方法，由于透明导电图形中位于重叠区域中的空置块的分布密度大于位于可视区域中的空置块的分布密度，位于重叠区域W中的空置块的分布密度较大，也即是，在单位面积中，重叠区域中的空置块的个数较多，重叠区域中的每个空置块的面积相对较小，在触摸驱动线或触摸感应线与空置块发生短路时，由于黑矩阵区内的空置块的面积较小，对触摸驱动线和触摸感应线之间的电容的大小的影响较弱，从而有效减少了对触控面板的触摸效果的影响。
本发明的另外的实施例提供一种触控装置，其包括本发明的上述实施例中任一实施例提供的触控面板10。本发明实施例提供的触控装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、 导航仪等任何具有触控显示功能的产品或部件。
本发明的又一实施例还提供一种触控面板40，如图18所示，触控面板包括：
衬底基板(图18未标示)。
在衬底基板上形成有黑矩阵401，黑矩阵位于衬底基板边缘的环形区域；
形成有黑矩阵的衬底基板上形成有透明导电图形402，透明导电图形和环形区域中的黑矩阵存在重叠区域，透明导电图形包括：多条横向设置的触摸驱动线触摸驱动线和多条纵向设置的触摸感应线触摸感应线，以及多个空置块，多条横向设置的触摸驱动线和多条纵向设置的触摸感应线相互绝缘，每个空置块形成所述透明导电图形中的一个独立图形单元；重叠区域中的任意两个相邻的图形单元的间隙宽度大于30um。
在一些实施例中，重叠区域中的任意两个相邻的图形单元的间隙宽度为100um。图18以100um为例进行了标示。
传统的触控面板20中，如图13所示，为了改善可视区域的光学效果，可视区域中相邻的各个图形单元的间隙宽度通常为30um(微米)，为了保证触控面板整体结构的均一性，透明导电图形上所有的图形单元的间隙宽度均设置为固定的宽度，也即是30um。
但是，发明人经过多次的实验证实，在透明导电图形和黑矩阵的重叠区域中，两个相邻的图形单元的间隙宽度越大，产生短路的概率越低，因此，在本发明实施例中，位于该重叠区域中的任意两个相邻的图形单元的间隙宽度可以大于30um。这样会有效降低重叠区域短路的概率。
但是，当黑矩阵区内的图形单元的间隙宽度增大时，单个触控单元的节点互容值会增大，当间隙宽度过大时(例如大于100um)，节点电容值的增大过多，这样黑矩阵区的节点电容值普遍比可视区域的节点电容值大很多，导致透明导电图形的均匀性差，影响触控面板边缘区域的触摸性能。与触摸驱动线、触摸感应线分别连接的驱动集成电路(英文：Integrated Circuit；简称：IC)芯片所能支持的间隙宽度的上限通常为100um(也即是，在间隙宽度为100um以内时，节点电容值在驱动IC芯片的可接受范围内，此时对触控面板边缘区域的触摸性 能影响不大)，为了保证驱动IC芯片的有效驱动，在一些实施例中，如图18所示，本发明实施例所提供的触控面板10中，重叠区域中的任意两个相邻的图形单元的间隙宽度D1为100um。可视区域的间隙宽D2度依然可以为30um。
综上所述，本发明实施例提供的触控面板，由于重叠区域中的任意两个相邻的图形单元的间隙宽度大于30um，可有效降低重叠区域短路的概率，并且，在任意两个相邻的图形单元的间隙宽度为100um时，能够在保证驱动IC芯片的有效驱动的前提下，实现尽量减少重叠区域短路的概率。
需要说明的是，本发明实施例中所述的“相邻”是指两个图形通过间隙绝缘，但是挨得很近。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
