在塑料基板具轻、薄、耐冲击及可挠曲的优势下,取代玻璃基板应用于各种光学镀膜及导电膜制镀是未来发展之趋势。但塑料基板上在镀膜上也遭遇到一些瓶颈待克服,如薄膜附着性、低温镀膜所造成膜质不佳等问题。本文旨将针对在塑料基板上制镀各种薄膜之技术,包含光学级塑料基板选择、镀膜前处理及表面改质、各种镀膜制程及其应用的近况做一简单介绍。
More attentions are being given to pPlastic based devices have received increasing attention because of owing to their potential properties such as lightweight, thin, flexible and high impact resistance on the applications of integrated circuits (IC) and flat panel displays. Nowadays the Current demands on the flexible devices are more robust, high-thermal enduring that could be suitable appropriate for various kind of vacuum coating processes. This paper will illustratearticle describes the applications of vacuum coating technology on a plastic substrate. ThatExactly how to select a moderately plastic substrate for the vacuum coating purpose, pre-treatment of plastic substrate and various of coating process are is also discussed in this paper.
一、前言
未来塑料基板取代玻璃基板成为次世代显示器材料是可期的。因为塑料基板拥有较玻璃基板之轻、薄、耐冲击、可卷曲等优势,可应用于许多可携式及穿戴式显示装置,以提高使用寿命并增加使用范围。目前塑料基板镀膜在光电产业的应用有:
(一) 透明导电薄膜(Transparent Con-ductive Film):
利用塑料基材的特性,镀上透明导电膜作为电极,应用于触控式面板屏幕、液晶显示面板(LCD panel)、有机发光二极管(OLED)、电子书(e-book) 等,可增加产品的竞争力。除了更轻更薄外,可挠曲的基板优点更是未来被光电产业应用所吸引的主因。
(二) 抗反射防静电薄膜(Anti-reflection/ Anti-static):
抗反射膜能增加对比、降低反射并增加穿透率,同时经由膜层的设计,尚能有抗静电、耐污、防紫外线照射破坏的功能。以往将抗反射膜镀于玻璃上的需求已明显降低,取而代之的是在镀于塑料基材如偏光板、lightguide等,以增加产品的功能性。
(三) 表面硬化膜(hard coating):
