Description

偏光片贴附品质检测系统及方法 技术领域
本申请涉及一种品质检测方法，特别是涉及一种偏光片贴附品质检测系统及方法。
背景技术
液晶显示面板通常是由一彩膜基板(Color Filter，CF)、一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)以及一配置于两基板间的液晶层(Liquid Crystal Layer)所构成，其工作原理是通过在两片玻璃基板上施加驱动电压来控制液晶层的液晶分子的旋转，将背光模组的光线折射出来产生画面。按照液晶的取向方式不同，目前主流市场上的液晶显示面板可以分为以下几种类型：垂直配向(Vertical Alignment，VA)型、扭曲向列(Twisted Nematic，TN)或超扭曲向列(Super Twisted Nematic，STN)型、平面转换(In-Plane Switching，IPS)型及边缘场开关(Fringe Field Switching，FFS)型。
而在液晶显示器中，偏光片乃是不可或缺的构成组件之一，其用途是将原本不具偏极性的光线，产生偏极化，转变成偏极光，因此，液晶显示器就能利用此偏极光，加上液晶分子本身的扭转特性，来控制光线的通过与否以及色彩讯号的呈现。而近年来，随着液晶显示组件被广泛地应用于诸如文字处理器(Word Processor)、计算机屏幕、手机或液晶电视等各种电子设备中，偏光片的需求量也越来越大。因此如何提升生产制程效率与减少制程流程步骤，将是经营者须面对的经营问题。

为更进一步阐述本申请为达成预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本申请提出的一种偏光片贴附品质检测系统及方法其具体实施方式、结构、特征及其功效，详细说明如后。
一种偏光片10的剖面结构如第1a图所示，其主要包含有离形膜12、感压胶层14、聚乙烯醇(Polyvinyl Alcohol，以下简称为PVA)偏光基体层18、三醋酸纤维素(Triacetyl Cellulose，以下简称为TAC)支撑膜16与20，以及保护膜22。有时候，为了防止反射现象，偏光膜表面还会再予特殊处理，例如加上一层抗炫(Anti-glare)层或者抗反射层(Anti-reflection)。目前，市场上的偏光片仍以碘系偏光片为主流，这是因为碘系偏光片具有高光穿透性、高对比度，且具有较广域波长的偏光特性，而其制造上较为容易，相对也使其价格较为便宜。
