Description

触摸屏、 显示屏和触摸屏制作方法
技术领域
本发明实施例涉及通信技术领域, 尤其涉及一种触摸屏、 显示屏和触摸 屏制作方法。 背景技术
触摸屏 (Touch Panel, 简称 TP) 作为人机交互模块, 在手机、 平板电脑 和个人计算机 (Personal Computer, 简称 PC ) 等电子设备中的应用越来越广 泛, 对其尺寸 (薄厚度和大尺寸) 和成本 (低成本) 的要求也越来越高。 轻 薄型电子设备因可以实现更好的视觉性能、 握触手感和便携性, 一直是业界 追求的目标。
TP主要包括保护盖板(cover lens )和触感层(sensor) 。 保护盖板可以是 玻璃、 蓝宝石、 聚碳酸酯 PC、 聚甲基丙烯酸甲酯 (Polymethyl Methacrylate, 简称 PMMA) 等。 触感层包括触控电极和基材, 触控电极目前常用的是氧化 铟锡 (Indium Tin Oxide, 简称 ITO ) 材料, 一些新型的 ΙΤΟ替代材料, 如金属 网 (metal mesh) 、 金属纳米线 (nano wire) 、 碳纳米管和石墨烯等也可作为 触控电极材料; 基材一般为玻璃、 聚对苯二甲酸乙二醇酯 (Polythylene Terephthalate, 简称 PET ) 、 环烯烃聚合物 (Cyclo Olefin Polymer, 简称 COP) 触感层在触摸屏、液晶显示屏 (Liquid Crystal Display, 简称 LCD)的位置会 影响电子设备的性能、 厚度和成本。
图 1为现有技术中的显示屏 GFF结构示意图, 图 1A为现有技术中的显示屏 GF结构示意图, 图 1B为现有技术中的显示屏 GF2结构示意图, 图 1C为现有技 术中的显示屏 GG结构示意图。 如图 1、 图 1A、 图 1B、 图 1C所示, 目前最常用 的结构为薄膜式(Glass-Film-Film, 简称 GFF) I ( Glass-Film, 简称 GF) / GF2/ 玻璃式(Glass-Glass, 简称 GG) GFF/GF/GF2/GG或 (plexiglass-Film-Film, 简 称 PFF ) I (plexiglass-Film, 简称 PF ) /PF2架构。 GFF/GF/GF2架构是 sensor制 备在 PET基材上, 然后用光学胶 (Optical Clear Adhesive, 简称 OCA) 等将两 层或单层的触感层贴合到保护盖板和液晶显示模块 (LCD Module,简称 LCM) 之间。 GG架构是触感层制备在玻璃上, 然后和保护盖板贴合。 采用上述的 TP/LCD架构, 贴合良率低, 保护盖板、 触感层、 PET、 LCD每经过一道贴合 制作程序, 良品率就会大打折扣; 同时由于 PET基材和 OCA胶的存在, TP/LCD 结构的厚度和用材成本都会增加。
为了实现电子设备的轻薄化, 现有技术一中采用一体化触控 (One Glass Solution, 简称 OGS ) 技术就是把触感层与保护玻璃集成在一起, 在保护玻璃 内侧镀上 ITO导电层, 直接在保护玻璃上进行镀膜和光刻, 由于节省了一片玻 璃和一次贴合, 触摸屏能够做的更薄且成本相对较低。 由于 OGS保护玻璃和 触感层是集成在一起的, 通常为了提高生产效率而采用大片制程, 需要先强 化保护玻璃, 然后镀膜、 蚀刻等, 最后切割。 强化过的玻璃切割是非常困难 的, 为了方便或能够切割, OGS保护玻璃的强化深度要浅, 这影响了最终 OGS 触摸屏的强度; 并且最后切割玻璃会造成玻璃边沿形成一些毛细裂缝, 这些 裂缝也降低了保护玻璃的强度。
现有技术中也有采用 In-Cell技术和 On-Cell技术, In-Cell技术是指将触摸屏 功能嵌入到液晶像素中的方法, 即在显示屏内部嵌入触摸传感器功能, 这样 能使屏幕变得更加轻薄; On-Cell技术是指将触摸屏嵌入到显示屏的彩色滤光 片基板和偏光片之间的方法, 即在液晶显示屏上配触摸传感器。 采用 In-Cell 技术和 on-cell技术制作触摸屏由于需要整合到 LCD当中, 增加了工艺流程, 制 程相对复杂、 良品率偏低、成本高。采用 In-Cell技术制作触摸屏还要嵌入配套 的触控 IC, 否则很容易导致错误的触控感测信号或者过大的噪音。
现有技术中存在的问题是, 制程复杂、 成本高。 发明内容 本发明实施例提供一种触摸屏、 显示屏和触摸屏制作方法, 以克服现有 技术中触摸屏制程复杂、 成本高的问题。
第一方面, 本发明实施例提供一种触摸屏, 包括: 保护盖板、 显示屏, 所述显示屏包括: 偏光片; 其中, 所述偏光片的保护层的表面设置有至少一 层的触感层, 所述触感层包括触控电极。
结合第一方面, 在第一方面的第一种实现方式中, 所述偏光片包括第一 保护层、 第二保护层和偏光片基体, 所述第一保护层和所述第二保护层分别 位于所述偏光片的基体相对的两面; 其中, 所述偏光片的保护层的表面设置 有至少一层的触感层, 包括以下任意一种或者多种的组合:
