Description

触控屏及柔性显示器 技术领域
本发明涉及触控面板制造技术领域，尤其涉及一种触控屏及柔性显示器。
背景技术
轻薄化是柔性显示器发展的方向。触控屏(Touch)与用于水氧阻隔的水氧阻隔层(Barrier Film)是柔性显示器常用的两种材料。传统的做法是：Touch与Barrier layer分别制作在不同片柔性基材上，在柔性显示器中，这二者之间会用胶水进行粘合。传统的做法共有两片柔性基材，且二者之间需再用胶水进行粘合，不利于柔性显示器的轻薄化，不利于节省材料成本，也不利于模组贴合制程；柔性显示器的厚度越厚，贴合界面越多，越不利于弯折、卷曲、扭曲等机械性能的提升，限制了柔性显示器的使用。
发明内容
基于上述问题，本申请提供一种触控屏及柔性显示器，减小触控屏厚度，增强柔性屏应用。
本申请提供一种触控屏，包括触控层及层叠于水氧阻隔层，所述触控层包括基底层及导电膜层，所述导电膜层及水氧阻隔层层叠于所述基底层上。
其中，所述导电膜层与水氧阻隔层分别设于所述基底层两个相对的表面。
其中，所述导电膜层与水氧阻隔层层叠所述基底层的同一表面上。
其中，所述导电膜层与所述基底层连接，所述导电膜层层叠所述水氧阻隔层上。
其中，所述水氧阻隔层与所述基底层连接，所述水氧阻隔层层叠所述导电膜层上。
本申请所述的柔性显示器，包括柔性显示屏及叠于所述柔性显示的触控屏，其特征在于，触控屏包括触控层及层叠于水氧阻隔层，所述触控层包括基底层及导电膜层，所述导电膜层及水氧阻隔层层叠于所述基底层上。
其中，所述导电膜层与水氧阻隔层分别设于所述基底层两个相对的表面。
其中，所述导电膜层与水氧阻隔层层叠所述基底层的同一表面上。
其中，所述导电膜层与所述基底层连接，所述导电膜层层叠所述水氧阻隔层上。
其中，所述水氧阻隔层与所述基底层连接，所述水氧阻隔层层叠所述导电膜层上。
其中，所述柔性显示器包括偏光片，所述偏光片包括顶偏光膜、偏振层、底保护层，所述底保护层、偏振层、顶偏光膜依次层叠于所述触控屏上。
本发明所述的触控屏中将导电膜层的基底层作为水氧阻隔层的基板，相较于现有技术节省了一层基板，进而减小了触控屏整体厚度，提高柔性触控屏的弯折、扭曲的性能。

请参阅图4，在其它实施方式中，所述水氧阻隔层13层叠于所述导电膜层12上。所述水氧阻隔层13可以对导电膜层12起到保护作用。
请参阅图5，本申请第三实施例中，所述导电膜层12与水氧阻隔层13层叠第二表面112上。其中一种实施方式是，所述水氧阻隔层13与所述基底层11连接，所述导电膜层12层叠于所述水氧阻隔层13上。

本发明所述的触控屏中将导电膜层的基底层作为水氧阻隔层的基板，相较于现有技术的具有独立的承载基板的导电膜层与偏光片均为单独制作，再通过胶水粘贴来说，本申请的触控屏节省了一层基板，进而减小了触控屏整体厚度，提高柔性触控屏的弯折、扭曲的性能。
以上所述是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
