Description

触控基板和触控显示装置 技术领域
本发明的实施例涉及一种触控基板和触控显示装置。
背景技术
一体化触控(One Glass Solution，OGS)已成为目前触控产业的主导技术方向。OGS只需一层玻璃，使得自身的重量、厚度大幅降低，同时透光性提高，因此能够较好地满足智能终端轻薄化需求并且提升显示效果。
已知技术中的OGS包括横向和纵向交叉设置的触控电极。由于触控电极自身具有一定的电阻，使得通过信号线向该触控电极输入信号时，远离信号输入端处的触控电极接收的信号发生衰减，导致远离信号输入端处的触控电极接收的信号强度明显小于靠近信号输入端处的触控电极接收的信号强度，或者根本无法接收到信号，从而使得该OGS触控屏无法精确地进行触控检测。
发明内容

在一个示例中，每个所述图案组中所述两个绑定图案的相邻侧边上均具有凹部和凸部，并且其中一个所述绑定图案的凸部伸入另一个所述绑定图案的凹部中。
在一个示例中，所述绑定图案的凸部的形状为矩形、三角形和梯形中的一个，并且所述绑定图案的凹部的形状与所述凸部的形状互补。
在一个示例中，每个所述图案组中所述两个绑定图案的相邻两个侧边上分别设置有均匀分布的多个凹部和凸部。
在一个示例中，每个所述图案组中所述两个绑定图案的间距大于或等于10μm。
在一个示例中，多个所述图案组沿所述图案组的宽度方向并列设置。
在一个示例中，相邻所述图案组的间距大于每个所述图案组中所述两个绑定图案的间距。
在一个示例中，相邻所述图案组的间距为50μm至150μm。
另一方面，提供了一种触控显示装置，包括上述任一种的触控基板。

具体实施方式
为使本发明的实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图对本发明的实施例的技术方案进行清楚、完整的描述。显然，所描述的实施例仅是本发明的一部分示例性实施例，而不是全部的实施例。基于所描述的本发明的示例性实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其它实施例都属于本发明的保护范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本发明专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“上”、“下”、等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
为了解决已知OGS技术中的前述缺陷，图1示出了一种采用双边走线的方案，即：从双侧同时向触控电极10输入信号，以减小触控电极10上不同位置处接收的信号强度不同的问题。
图1仅以一个横向触控电极10连接一组双边走线为例进行举例说明。如图1所示，上述双边走线分别通过与其相连接的绑定图案20(Bonding PIN，也可称为PIN)与柔性印刷电路板(Flexible Printed Circuit，简称为FPC)进行绑定(Bonding)，其中双边走线的PIN 20分布在同一列(即，沿PIN的长度方向分布)，通过导电胶(Anisotropic Conductive film，简称为AFC)与FPC连接。导电胶在连接PIN 20和FPC时需要一定的按压力，使导电胶中的导电粒子发生破裂，才能实现PIN 20和FPC的电连接。
然而，在按压过程中，如图1所示，由于两个PIN 20沿其长度方向呈一列分布，使得两个PIN的总长度较长，故而在按压时容易导致按压力不均匀(例如：可能仅按压到了其中一个PIN 20、而按不到另一个PIN 20)，使得这两个PIN 20上的导电胶中的导电粒子不能充分破裂，进而导致双边走线中的一侧走线不能与FPC上的端口电连接，从而不能接收到信号，由此可能无法实现采用双边走线期望达到的效果，仍会出现触控电极10接收的信号强度不同的问题。
本发明的实施例提供一种触控基板，如图2所示，该触控基板01包括在衬底基板上横纵交叉设置的多个触控电极10，其中，图2仅是以两个横向触控电极10为例进行示意的。分别与同一个触控电极10的两端连接的两个绑定图案20构成一个图案组200，其中，每个图案 组200中的两个绑定图案20沿绑定图案的宽度方向W-W’并列设置，并且这两个绑定图案20相邻且互不接触。
由于上述触控基板中的触控电极两端分别连接的两个绑定图案构成图案组，且该图案组中的相邻且不接触的两个绑定图案沿该绑定图案的宽度方向并列设置，在此情况下，一方面，相比于图1所示方案中两个绑定图案沿长度方向呈一列构成的长度(至少为两个绑定图案长度之和)而言，图2所示实施例中沿宽度方向并列设置的两个绑定图案组成的图案组的长度为单个绑定图案的长度，从而使得该图案组的长度减小，进而能够减小因图案组的长度过长导致的受力不均。另一方面，该图案组中两个绑定图案在宽度方向上相邻且不接触，当绑定图案与柔性印刷电路板进行绑定时，按压头将沿该宽度方向进行按压，因此在宽度方向上，能够保证绑定图案受到比较均匀的按压力。综上所述，当包括上述图案组的触控基板与柔性印刷电路板进行绑定时，能够减小因图案组的长度过长导致的受力不均，进而降低双边走线的绑定图案与柔性印刷电路之间导通不良的几率。
此处需要说明的是，两个绑定图案20相邻且互不接触是指，在一个图案组200中的两个绑定图案20为两个独立结构，两者之间不连接。本领域的技术人员应该理解到，如果图案组200中的两个绑定图案20直接连接形成一体结构，当该一体结构的绑定图案20直接与FPC上的一个金手指进行绑定时，容易导致该一体结构通过双边走线向触控电极10的两端分流的信号强度不同，进而造成触控检测不准确的现象，因此，需要保证一个图案组200的两个绑定图案20互不接触且形状大小相同，以使得两个绑定图案20上传输的信号强度相同。
另外，当上述触控基板01通过导电胶与FPC进行绑定时，现有的导电胶中的导电粒子的直径一般在5μm左右，并且导电粒子在受压时会发生一定的形变，从而使得导电粒子与FPC的接触面积增加。因此，为了避免在按压过程中一个导电粒子同时跨越相邻的两个绑定图案20而导致两个绑定图案20之间发生电连接，在一个示例中，相邻两个绑定图案的间距可大于或等于10μm，以避免向触控电极10的两端分流的信号强度不同的现象。
在此基础上，上述触控基板01中包括横纵交错的多个触控电极10， 为了便于对包括多个触控电极10相连接的各个绑定图案20的触控基板01进行集成化控制，如图2所示，可以将多个图案组200沿图案组的宽度方向(也即绑定图案的宽度方向W-W’)并列设置，其中图2是以两个图案组200为例进行说明的。
在一个示例中，由于与一个触控电极10连接的一个图案组200中的两个绑定图案20上的输入信号和输出信号一致，因此同一个图案组200中的两个绑定图案20不存在信号干扰现象；而对于不同的触控电极10，由于需要通过对各个触控电极10进行单独的信号输入和输出以实现触控位置的检测，因此相邻图案组200的间距大于每个图案组200中两个绑定图案20的间距，以避免相邻两个图案组200中的信号发生干扰。
在一个示例中，相邻图案组200间距为50μm至150μm，能够在避免相邻两个图案组200中的信号发生干扰的同时实现对触控基板01的集成化控制。
在此基础上，当绑定图案20与FPC进行绑定并且按压头沿绑定图案宽度方向W-W’进行按压时，对于同一图案组200中的两个绑定图案20，在该宽度方向上仍然可能出现一个绑定图案20受到按压而另一个绑定图案20未受到按压的情况，进而导致双边走线的绑定图案20与FPC之间导通不良。为了解决该技术问题，在一个实施例中，如图3a所示，同一图案组200中的两个绑定图案20的相邻侧边上均具有凹部201和凸部202，其中一个绑定图案20的凸部202伸入另一个绑定图案20的凹部201中。以此方式，当在按压头沿绑定图案宽度方向W-W’进行按压时，能够进一步增加上述两个绑定图案20同时受到按压的几率，从而进一步降低了双边走线的绑定图案20与FPC之间导通不良的几率。
在此基础上，为了进一步增加同一图案组200中两个绑定图案20同时受到按压的几率，在一个实施例中，如图3a所示，在上述两个绑定图案20的相邻两个侧边分别设置有均匀分布的多个凹部201和凸部202。
对于上述绑定图案20的凹部201和凸部202的设计，可以如图3a所示，凹部201为矩形，凸部202形状与该凹部201形状互补，即也为 矩形；还可以如图3b所示，凹部201为梯形，凸部202形状与该凹部201形状互补，即也为梯形；当然，凹部201还可以为三角形，此时凸部202形状与该凹部201形状互补，即也为三角形；本发明的实施例对此不作限定，只要能够使得同一图案组200中一个绑定图案20的凸部202与另一绑定图案20的凹部201形状互补从而可以伸入该凹部201中即可，以提高同一图案组200中两个绑定图案同时受到按压的几率。
本发明的实施例还提供一种触控显示装置，该触控显示装置包括上述任一实施例中的触控基板，由此也具有与前述实施例提供的触控基板相同的有益效果。由于前述实施例已经对触控基板的结构和有益效果进行了详细的描述，此处不再赘述。
需要说明的是，在本发明的实施例中，触控显示装置至少可以包括液晶显示装置和有机发光二极管显示装置。例如，本发明实施例提供的触控显示装置可为液晶显示器、液晶电视、数码相框、手机或平板电脑等任何具有触控显示功能的产品。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
