Description

触控面板及显示设备 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种触控面板及显示设备。
 背景技术
随着触摸屏技术的发展，以及消费者对触控产品外观及触控感受的要求越来越高，越来越多的触控屏方案商采用先进工艺技术希望将触控屏黑边框做的越来越窄，甚至无边框。
现有触控面板的简化示意图如图1所示，为了实现触控的识别，除了需要在FPC（Flexible Printed Circuit，柔性电路板）所在端部a设置连接端子以及走线之外，还需要在两个侧边（b和c）设置连接端子以及走线。
即传统的触控屏通过丝印导电金属线作为触控电极与外部处理器间电信号传递的媒介，为了掩盖此信号导线，触控屏基板上需要增加一个宽的、不透明的、用来遮挡走线区的边框，此设计使触控屏的边框较宽。为了使触控屏在有限的尺寸上显示尽量多的内容，将信号导线所占据的边框面积减小，极力营造无视界的显示效果，是提高市场竞争力的关键所在。

采用溅射蒸发方法，在透明基板的两个表面同时镀上一层氧化铟锡ITO。
S703：在氧化铟锡上图案化处理形成间隔线。
采用光刻法等方式，在氧化铟锡上图案化处理形成间隔线，间隔线将氧化铟锡分割为触控区域。
S704：设置连接端子。
采用柔性金属，在基板的侧边设置连接端子，各连接端子分别连接一个触控区域。
S705：连接柔性电路板。
将柔性电路板与各连接端子电连接，并封装，生成最终的触控面板。
根据上述实施例可知：
本发明通过在基板2个表面分别设置触控膜层，并通过图案化间隔线，将触控膜层分割为触控区域，并且仅在基板的一个侧边设置连接端子以及走线；相较于现有技术中需要在3个侧边设置连接端子及走线的方式，减少了需要设置连接端子及走线的侧边数量，这样就是实现触控面板的无边框设计，满足消费者对触控产品外观及触控感受的要求。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
