Description

触控面板及其制造方法 技术领域
本发明系有关触控技术领域，尤其涉及一种触控面板及其制造方法。
背景技术
触控面板（Touch Panel）已大量运用于消费、通讯、电脑等电子产品上，例如目前广泛使用的游戏机、智慧手机、平板电脑等，作为众多电子产品的输入输出界面。
触控面板一般包括布线板、设置于布线板上的感测电极层、线路层、保护层等。其中感测电极层一般为多个行电极、多个列电极相互交错形成的感应矩阵，且各感应矩阵中的行电极与列电极的交错点通过矩形绝缘垫隔开，防止在交错点相互短路。触控面板制造过程包含风刀、水洗等清洁步骤，在这些步骤中，绝缘垫在同一水平面上将受到风刀或水洗等外部冲击力的作用。但因为矩形形状的绝缘垫，其边缘与该些外部冲击力的方向是垂直关系，而使其单一受力边缘直接承受所有的外部冲击力，造成无法有效地分散冲击力，导致矩形绝缘垫存在较易断裂的问题。
发明内容
基于此，有必要提供一种绝缘垫抗冲击力强的触控面板，解决绝缘垫容易断裂的问题，以提高触控面板制程的良率。
一种触控面板，包括沿一第一方向排列的第一感应线、与所述第一感应线交叉的沿一第二方向排列的第二感应线、位于所述第一感应线与所述第二感应线交叉点将所述第一感应线与所述第二感应线绝缘隔开的绝缘垫，所述绝缘垫的边缘与外部冲击力的冲击方向在同一水平面上是非垂直关系。
在其中一个实施例中，所述绝缘垫中部沿该第一方向具有至少一延伸部分，及/或所述绝缘垫中部沿与该第一方向相反的方向具有至少一延伸部分。
在其中一个实施例中，所述第一感应线包含多个第一电极和多个连接相邻的所述第一电极的第一导线，所述第二感应线包含多个第二电极和多个连接相邻的所述第二电极的第二导线，其中所述第一电极、所述第二电极与所述第一导线是位在同一平面上。在其中一个实施例中，所述第一导线与所述第二导线的交叉点形成有所述绝缘垫。在其中一个实施例中，所述绝缘垫形成有过孔，且所述第二导线的两端通过设置在该绝缘垫的过孔而与所述第二电极连接。
在其中一个实施例中，所述绝缘垫是一非矩形形状的绝缘垫。
在其中一个实施例中，所述绝缘垫为六边形绝缘垫、菱形绝缘垫、椭圆形绝缘垫、八边形绝缘垫或葫芦形绝缘垫。在其中一个实施例，所述六边形绝缘垫延伸部分的内角角度大于90度。
在其中一个实施例中，所述六边形绝缘垫沿所述第一方向的长度为200微米至500微米，所述六边形绝缘垫沿所述第二方向的长度为300微米至700微米。
在其中一个实施例中，所述绝缘垫的厚度为1.1微米至1.9微米。
在其中一个实施例中，所述绝缘垫的侧面为斜面。
在其中一个实施例中，所述斜面与所述多个第一电极、所述第一导线所在平面的夹角大于30度小于80度。
此外，还有必要提供一种触控面板制造方法，包括如下步骤：
在一布线板上形成多个沿一第一方向排列的第一电极、多个导通连接相邻的所述第一电极的第一导线，以及多个沿第二方向排列的第二电极；在所述第一导线上分别形成绝缘垫，其中所述绝缘垫的边缘与外部冲击力的冲击方向在同一水平面上是非垂直关系；及在各所述绝缘垫上形成连接相邻的所述第二电极的第二导线。
在其中一个实施例中，所述绝缘垫中部沿该第一方向具有至少一延伸部分，及/或所述绝缘垫中部沿与该第一方向相反的方向具有至少一延伸部分。
上述触控面板，通过对绝缘垫形状的改良，改良后绝缘垫的边缘与外部冲击力的冲击方向在同一水平面上是非垂直关系，改良后的绝缘垫可以有效分散制程过程中的冲击力作用，增强绝缘垫的抗冲击能力，从而提高触控面板制程的良率。

具体实施方式
如图1所示，触控面板界定有一第一方向X及第二方向Y，在一较佳情况下，该第一方向X与该第二方向Y垂直。该触控面板包括沿第一方向X排列的第一感应线120、绝缘垫130与沿第二方向Y排列的第二感应线140。该触控面板更包括布线板110，此处的布线板110可以是传统触控面板采用的可透视的玻璃基板或者塑胶基板等，所述布线板110用以承载及/或保护形成在其上面的各元件，如第一感应线120、绝缘垫130与第二感应线140等。第一感应线120设置在布线板110上，第二感应线140与第一感应线120交叉。绝缘垫130位于第一感应线120与第二感应线140交叉点将第一感应线120与第二感应线140绝缘隔开，其中所述绝缘垫130的边缘与外部冲击力(如风刀或水洗等)的冲击方向在同一水平面上是非垂直关系。此非垂直关系可以分散绝缘垫130单一边缘在制程中遭受全部的冲击力（如冲击力沿着第一方向X或沿着与第一方向相反的方向冲击绝缘垫），而增强绝缘垫130的抗冲击程度，防止绝缘垫断裂，从而提高触控面板制程的良率。
其中，上述的绝缘垫可以是一非矩形形状的绝缘垫，或是所述绝缘垫的中部沿第一方向X有一延伸部分且沿与第一方向X相反的方向亦有一延伸部分，以下将以多个实施例揭露不同样态的绝缘垫及触控面板内部的详细结构。
如图2所示，图2绘示了一种可用于图1触控面板的结构。本实施例中，第一感应线220包括多个第一电极222及导通连接多个第一电极222的多个第一导线224，第二感应线240包括多个第二电极242及导通连接多个第二电极242的多个第二导线244。第二导线244可以采用金属材料或氧化铟锡（Indium Tin Oxides，简称ITO）材料制成。绝缘垫230位于第一导线224与第二导线244交叉点处，将第一导线224与第二导线244绝缘隔开。本实施例中，第二导线244的长度大于绝缘垫230的长度，第二导线244的两端直接与两个相邻的第二电极242连接。绝缘垫230可为一菱形绝缘垫，该菱形绝缘垫230沿第一方向X形成有一延伸部分，该延伸部分使得该菱形绝缘垫230受外部冲击力的边缘有复数个，藉此可以分散制程中风刀、水洗的冲击力量（如图2所示的F），进而减少绝缘垫被刮断的现象。在本实施例中，该菱形绝缘垫230沿与第一方向X相反的方向也形成有一延伸部分，藉由两侧都形成有延伸部分的菱形绝缘垫可确保分散来自不同方向的冲击力量。
如图3所示，图3绘示了又一种可用于图1触控面板的结构。本实施例中，第一感应线320包括多个第一电极322及多个导通连接两两相邻第一电极322的第一导线324，第二感应线340包括多个第二电极342及多个导通连接两两相邻第二电极342的第二导线344。第二导线344可以采用金属材料或氧化铟锡（Indium Tin Oxides，简称ITO）材料制成。绝缘垫330位于第一导线324与第二导线344交叉点上，将第一导线324与第二导线344绝缘隔开。本实施例中，第二导线344的长度小于绝缘垫330的长度，第二导线344的两端通过设置在绝缘垫330的过孔310与第二电极342连接。绝缘垫330为菱形绝缘垫。该菱形绝缘垫330的其它特性和作用与图2所绘示的实施例相同，此处不再赘述。
如图4所示，图4绘示了又一种可用于图1触控面板的结构。本实施例中，第一感应线420包括多个第一电极422及导通连接多个两两相邻第一电极422的多个第一导线424，第二感应线440包括多个第二电极442及导通连接多个两两相邻第二电极442的多个第二导线444。第二导线444可以采用金属材料或氧化铟锡（Indium Tin Oxides，简称ITO）材料制成。绝缘垫430位于第一导线424与第二导线444交叉点处，将第一导线424与第二导线444绝缘隔开。本实施例中，第二导线444的长度大于绝缘垫430的长度，第二导线444的两端直接与第二电极442连接。绝缘垫430采取六边形绝缘垫。在本实施例中，六边形绝缘垫430沿第一方向X形成有一延伸部分，且与第一方向X相反的方向也形成有一延伸部分。两侧都形成有延伸部分的六边形绝缘垫可行确保分散来自不同方向的冲击力量。
如图5所示，图5绘示了又一种可用于图1触控面板的结构。本实施例中，第一感应线520包括多个第一电极522及导通连接多个两两相邻第一电极522的多个第一导线524，第二感应线540包括多个第二电极542及导通连接多个两两相邻第二电极542的多个第二导线544。第二导线544可以采用金属材料或氧化铟锡（Indium Tin Oxides，简称ITO）材料制成。绝缘垫530位于第一导线524与第二导线544交叉点上，将第一导线524与第二导线544绝缘隔开。本实施例中，第二导线544的长度小于绝缘垫530的长度，第二导线544的两端通过设置在绝缘垫530的过孔510与第二电极542连接。绝缘垫530采取六边形绝缘垫。在本实施例中，六边形绝缘垫530沿第一方向X形成有一延伸部分，且与第一方向X相反的方向也形成有一延伸部分。两侧都形成有延伸部分的六边形绝缘垫可行确保分散来自不同方向的冲击力量。
在一实施例中，六边形绝缘垫430或六边形绝缘垫530延伸部分的内角角度 α 大于90度。内角角度 α 大于90度，保证六边形绝缘垫沿第一方向向外凸出，该延伸部分可有效分散外力的冲击作用。
上述实施例中，六边形绝缘垫430或绝缘垫530沿第一方向X的长度为200微米至500微米，六边形绝缘垫430或绝缘垫530沿第二方向Y的长度为300微米至700微米。采用此规格的六边形绝缘垫，既能保证起到较好的绝缘隔离效果，又可避免对形成第二导线544造成不良影响，例如第二导线544需要过长或过窄等。
绝缘垫的形状并不仅限于以上提及的几种，图6、图7、图8为绝缘垫的其他变形，即为如图6所示的椭圆形绝缘垫630、亦可为如图7中所示的八边形绝缘垫730或者为如图8所示的葫芦形状绝缘垫830。
如图9所示，在一实施例中，绝缘垫930的侧面为斜面。绝缘垫930位于第一感应线920与第二感应线940交叉点。斜面与包括第一电极、第一导线的第一感应线920所在平面的夹角 β 大于30度小于80度。将绝缘垫的边缘设计成斜坡状，可以降低绝缘垫边缘阻值过大的问题。
在一实施例中，绝缘垫的厚度为1.1微米至1.9微米。将绝缘垫的厚度控制在上述数值范围内，既可以将触控面板的厚度控制在允许的范围内，有利于触控面板的超薄化，又能保证绝缘垫足够的强度。
上述实施例中，多个第一电极、多个第一导线、多个第二电极位于同一平面，多个第二导线位于另一平面，第一电极、第二导线、第二电极可采用相同的材料，如ITO、奈米银、奈米碳管等。上述实施中，各绝缘垫可采用环氧树脂等具绝缘特性的材料。
如图10示，在加工时，可采取如下步骤加工出上述触控面板：步骤S1：先准备布线板，具体为准备所需规格尺寸的布线板，通常采用可透视玻璃或塑胶制成。用清洗剂将布线板需进行加工面清洗干净并干燥。
步骤S2：在布线板上形成多个沿第一方向排列的第一电极、多个导通连接相邻的第一电极的第一导线，以及多个沿第二方向排列的第二电极，其中第一电极、第一导线及第二电极可同时或非同时形成；
步骤S3：在各第一导线上分别形成绝缘垫，各绝缘垫的边缘与外部冲击力的冲击方向在同一水平面上是非垂直关系，例如各绝缘垫可以是一非矩形形状的绝缘垫，或是各绝缘垫中部沿第一方向具有至少一延伸部分；及
步骤S4：在各绝缘垫上形成连接相邻第二电极的第二导线。
在一实施例中，步骤S3中，在第一导线上形成的绝缘垫，绝缘垫中部除了沿第一方向具有至少一延伸部分。在一实施例中，绝缘垫中部沿与第一方向相反的方向亦形成有至少一延伸部分。
在一实施例中，绝缘垫的厚度为1.1微米至1.9微米。将绝缘垫的厚度控制在上述数值范围内，既可以将触控面板的厚度控制在允许的范围内，有利于触控面板的超薄化，又能保证绝缘垫足够的强度。
在绝缘垫上形成第二导线，第二导线可为ITO导线或者金属导线。第二导线与第一导线交叉设置，绝缘垫将第一导线与第二导线绝缘设置。
在一实施例中，绝缘垫形成有过孔，且第二导线的两端通过设置在绝缘垫的过孔而与第二电极连接。
绝缘垫的侧面为位斜面。斜面的倾角 β 大于30度小于80度。将绝缘垫的边缘设计成斜坡状，还可以降低绝缘片边缘阻值过大的问题。
绝缘垫的形状可以是图2与图3所示的菱形、图4与图5所示的六边形、图6所示的椭圆形、图7中所示的八边形或者图8所示的葫芦形等。
上述触控面板制造方法提供一种绝缘垫的边缘与外部冲击力的冲击方向在同一水平面上是非垂直关系的触控面板，可以分散绝缘垫单一边缘在制程中遭受全部的冲击力，减少绝缘垫结构在制程中断裂的概率，提高触控面板的制程良率。
容易理解，只要是存在通过绝缘垫将交叉的导体隔离的需求的触控面板，都可以使用上述绝缘垫的结构及触控面板的制造方法。
以上所述仅为本发明的较佳实施例而已，并非用以限定本发明的申请专利范围；凡其它未脱离发明所揭示的精神下所完成的等效改变或修饰，均应包含在下述的申请专利范围内。
