具体实施方式
为使本发明实施例的目的、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，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，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他实施例，都属于本发明保护的范围。
除非另外定义，本公开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。本公开中使用的“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。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”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。
在研究中，本申请的发明人注意到，OGS技术一般采用6次掩膜板(Mask)工艺，一般在基板上采用至少两层绝缘层和透明电极制作架桥，多层绝缘层的最大问题点是桥点很容易被看到，尤其是架桥的线宽越宽，绝缘层的厚度越大，桥点更容易被看到。光线照射到OGS触摸屏架桥结构时，由于光在透明电极和绝缘层的透射或折射不一样导致桥点很容易被看到，影响显示效果。
为了提高显示装置的显示效果。本发明实施例提供了一种OGS触摸屏基板架桥结构及其制造方法、OGS触摸屏及其制造方法及显示装置，在本发明实施例的技术方案中，通过采用一层绝缘层和两层透明电极制作架桥结构，省去多余绝缘层的设置，当光线照射在架桥结构上时，光线在第二透明电极上的透射及反射的效果相同，不会出现光线的亮度的差别，进而减小了架桥结构被看到的可能性，提高了显示装置的显示效果。
实施例一
本发明实施例提供了一种OGS触摸屏基板架桥结构，所述架桥结构包括设置于基板上的一层绝缘层和两层透明电极，所述两层透明电极为第一透明电极和第二透明电极，所述绝缘层设置在第一透明电极上，所述第二透明电极设置在绝缘层上，所述第一透明电极包括多个间隔设置的子电极，所述第二透明电极将子电极电连接。
如图1和图2所示，所述OGS触摸屏基板的架桥结构20包括设置在基板10上的一层绝缘层14和两层透明电极(第一透明电极11和第二透明电极15)，所述绝缘层14设置在第一透明电极11上，所述第二透明电极15设置在绝缘层14上，所述第一透明电极11包括多个间隔设置的子电极，所述第二透明电极15将子电极电连接。
在上述实施例中，通过采用一层绝缘层14和两层透明电极(第一透明电极11和第二透明电极15)制作架桥结构20，省去多余绝缘层的设置，当光 线照射在架桥结构20上时，光线在第二透明电极15上的透射及反射的效果相同，不会出现光线的亮度的差别，进而减小了架桥结构20被看到的可能性,提高了显示装置的显示效果。
在一个示例中，第二透明电极15与子电极连接时，在绝缘层14上设置有过孔16，第二透明电极15通过所述过孔16与子电极连接。在制作过程中，在形成的绝缘层14上对应每个子电极刻蚀出过孔16，在绝缘层14上形成第二透明电极15时，第二透明电极15通过过孔16与子电极连接，从而将子电极进行串联。
实施例二
继续参考图1及图2，本发明实施例提供了一种OGS触摸屏，该OGS触摸屏包括上述任一项所述的架桥结构20。
在上述实施例中，通过采用一层绝缘层14和两层透明电极(第一透明电极11和第二透明电极15)制作架桥结构20，省去多余绝缘层的设置，当光线照射在架桥结构20上时，光线在第二透明电极15上的透射及反射的效果相同，不会出现光线的亮度的差别，进而减小了架桥结构20被看到的可能性，提高了显示装置的显示效果。
在一个示例中，所述触摸屏还包括设置于所述基板上的黑矩阵12及设置于所述黑矩阵12上的金属引线13，所述绝缘层14覆盖所述金属引线13。
在上述实施例中，绝缘层14将基板10上的金属引线13覆盖住，从而省去了6次掩膜板工艺中形成在基板上的至少两层绝缘层中的至少一层，采用一层绝缘层14即可实现对金属引线13的保护。以6次掩膜板工艺在基板上形成两层绝缘层为例，在光线照射到架桥结构20上时，由于本发明实施例提供的OGS触摸屏中没有采用第二绝缘层，因此，通过上述描述可以看出本实施例提供的OGS触摸屏，通过采用设置在第一透明电极11上的绝缘层14来覆盖金属引线13，从而减少了一层绝缘层；进而减少光的透射或折射差异，减小了看到桥点的可能性；同时减少了一道工序，提高了产能。
实施例三
继续参考图1及图2，本发明实施例提供了一种显示装置，该显示装置包括上述任一种所述的OGS触摸屏。该显示装置可以为：液晶面板、OLED面板、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪 等任何具有显示功能的产品或部件。
在上述实施例中，通过采用一层绝缘层14和两层透明电极(第一透明电极11和第二透明电极15)制作架桥结构20，省去多余绝缘层的设置，当光线照射在架桥结构20上时，光线在第二透明电极15上的透射及反射的效果相同，不会出现光线的亮度的差别，进而减小了架桥结构20被看到的可能性，提高了显示装置的显示效果。
实施例四
本发明实施例提供了一种OGS触摸屏基板架桥结构20的制造方法，该方法包括：在基板10上形成第一透明电极11，第一透明电极11包括多个子电极；在第一透明电极11上形成绝缘层14；以及在绝缘层14上形成第二透明电极15，该第二透明电极15将子电极电连接。
通过采用一层绝缘层14和两层透明电极(第一透明电极11和第二透明电极15)制作架桥结构20，省去多余绝缘层的设置，当光线照射在架桥结构20上时，光线在第二透明电极15上的透射及反射的效果相同，不会出现光线的亮度的差别，进而减小了架桥结构20被看到的可能性，提高了显示装置的显示效果。
在一个示例中，所述在绝缘层上形成第二透明电极，所述第二透明电极将所述子电极电连接包括：在绝缘层14上形成裸露每个子电极的过孔16；以及在绝缘层14上形成第二透明电极15，第二透明电极15通过所述过孔16与子电极连接。
通过在绝缘层14上设置过孔16，从而实现了第二透明电极15将多个子电极电连接。
本发明实施例还提供了一种OGS触摸屏的制造方法，该方法包括上述OGS触摸屏基板架桥结构20的制造方法。
在该方法中，通过采用一层绝缘层14和两层透明电极(第一透明电极11和第二透明电极15)制作架桥结构20，省去多余绝缘层的设置，当光线照射在架桥结构20上时，光线在第二透明电极15上的透射及反射的效果相同，不会出现光线的亮度的差别，进而减小了架桥结构20被看到的可能性，提高了显示装置的显示效果。
在一个示例中，OGS触摸屏的制造方法在制造所述架桥结构20之前还 包括：在所述基板10上形成黑矩阵12及所述黑矩阵12上方(黑矩阵12的远离基板10的一侧)的金属引线13，所述绝缘层14覆盖所述金属引线13。
为了方便对本实施例提供的方法的理解，下面对其步骤进行详细说明。
步骤一、黑矩阵12工艺制作，例如，采用构图工艺(例如包括曝光、显影)完成第一道Mask工序(此工序也可用打印方式等实现)，如图3a所示。
步骤二、第一透明电极11的形成，例如，采用构图工艺(例如包括曝光、显影、刻蚀、剥离)完成第二道Mask工序，此工序形成ITO Pattern图形，如图3b所示。
步骤三、金属引线的形成，例如，采用构图工艺(例如包括曝光、显影、刻蚀、剥离)完成第三道Mask工序，此工序将金属引线图形完成，如图3c所示。
步骤四、绝缘层14的形成，例如，采用构图工艺(例如包括曝光、显影)完成第四道Mask工序并在第一透明电极11的上方做架桥结构20的过孔16，同时将结合区(在结合区中，第一透明电极11的子电极与第二透明电极15电连接)金属露出来，其他地方或金属引线13全部用绝缘层14保护起来，如图3d所示。
步骤五、第二透明电极15的形成，例如，采用构图工艺(例如包括曝光、显影、刻蚀、剥离)完成第五道Mask工序，此工序通过在过孔处的连接形成架桥结构20，同时在结合区形成对金属引线进行保护的第二透明电极15，其他地方的透明电极材料全部刻蚀掉，如图3e所示。
在上述实施中，通过采用一层绝缘层14和两层透明电极(第一透明电极11和第二透明电极15)制作架桥结构20，省去多余绝缘层的设置，当光线照射在架桥结构20上时，光线在第二透明电极15上的透射及反射的效果相同，不会出现光线的亮度的差别，进而减小了架桥结构20被看到的可能性,提高了显示装置的显示效果。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
本申请要求于2014年9月11日递交的中国专利申请第201410462843.3号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
