Description

具标记检查的偏光板贴附装置及其检查方法 技术领域
本申请涉及一种改善偏光板误配的方法，特别是涉及一种具标记检查的偏光板贴附装置及其检查方法。
背景技术
一般液晶平面显示器若依驱动显示方式，可分为简单矩阵型与主动矩阵型两种，简单矩阵型显示器主要是在上、下面板分别设置交错的透明电极及填充液晶，电极交差的格子状部位就是液晶面板的画素，两方向的电极是由外部提供驱动电压来控制画素的两极电位差，达成驱动画素中液晶的转动；而主动矩阵型显示器则是在面板上的每一画素位置点上设置开关组件及储存讯号的辅助电容，各画素驱动是由画素上的薄膜晶体管组件独立控制。
不论是简单矩阵型显示器或主动矩阵型显示器，其面板外侧均须贴附一片偏光板，主要用途是在有电场与无电场时使光源产生位相差而呈现明暗的状态，用以显示字幕或影像，若面板与偏光板间残留有异物、杂质等污染物时，则会影响显示的品质，因此显示器的液晶面板在制作过程中保持面板及偏光板的清洁与对位就相当重要。
在液晶显示器中，偏光板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，偏光板的需求量也越来越大。因此如何提升生产制程效率与提高产品良率，将是经营者须面对的经营问题。

本发明的实施方式
以下各实施例的说明是参考附加的图式，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。
附图和说明被认为在本质上是示出性的，而不是限制性的。在图中，结构相似的单元是以相同标号表示。另外，为了理解和便于描述，附图中示出的每个组件的尺寸和厚度是任意示出的，但是本申请不限于此。
在附图中，为了清晰起见，夸大了层、膜、面板、区域等的厚度。在附图中，为了理解和便于描述，夸大了一些层和区域的厚度。将理解的是，当例如层、膜、区域或基底的组件被称作“在”另一组件“上”时，所述组件可以直接在所述另一组件上，或者也可以存在中间组件。
另外，在说明书中，除非明确地描述为相反的，否则词语“包括”将被理解为意指包括所述组件，但是不排除任何其它组件。此外，在说明书中，“在......上”意指位于目标组件上方或者下方，而不意指必须位于基于重力方向的顶部上。
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具标记检查的偏光板贴附装置及其检查方法其具体实施方式、结构、特征及其功效，详细说明如后。
偏光板，其在至少一面上具有含有相位差薄膜的功能的层合光学薄膜。构成所述偏光板的偏光子，例如对于聚乙烯醇(PVA)或PVA之一部分进行甲醛化的聚合物等所构成的薄膜，以适当的顺序或方法实施以碘或二色性染料等所构成的二色性物质的染色处理、拉伸处理、交联处理等所得的薄膜，自然光入射时，成为直线偏光而透过。特佳为使用光的透过率高，偏亮度优异。
构成偏光板的偏光子的厚度一般适合使用5～80μm。偏光子除了上述PVA系薄膜外，具有同样特性的其他薄膜也可使用。例如由环状烯烃系树脂所构成的薄膜，以适当的顺序或方法实施染色处理、拉伸处理、交联处理等，或涂布二色性物质的溶液，使其配向，或为线栅(Wire Grid)型的偏光子。
通常，偏光板由偏光子、相位差薄膜、保护薄膜所构成，但是以构成偏光板的相位差薄膜的形态，将层合光学薄膜介于接着剂或黏着剂，贴合于偏光子的至少一面来使用。层合光学薄膜可在A层侧与偏光子贴合，或在B层侧与偏光子贴合。这种偏光板因相位差薄膜具有优异的耐热性、耐湿性、耐药品性等特性，且具有作为保护薄膜的充分的功能，因此在偏光子上被层合具有作为相位差薄膜功能的层合光学薄膜的面上，可不必在另外层合保护薄膜。所述偏光板为仅在偏光子的单面被层合具有作为相位差薄膜功能的层合光学薄膜的构成时，偏光子的另一面可被层合例如三乙酰基 纤维素(TAC)、环状烯烃系树脂薄膜、丙烯酸系树脂薄膜等公知的保护薄膜。
所述层合光学薄膜与偏光子的贴合、保护薄膜与偏光子的贴合是将各层介于感压接着剂、热硬化接着剂、光硬化性接着剂等公知的接着剂或黏着剂，予以接着来制造。黏着剂、较佳为透明性优的接着剂，具体而言，例如天然橡胶、合成橡胶、乙酸乙烯/氯乙烯共聚物、聚乙烯醚、聚乙烯醇、丙烯酸系树脂、改性聚烯烃系树脂等的黏着剂及具有羟基、胺基等的官能基的前述树脂等中添加含有异氰酸酯基的化合物等硬化剂的硬化型黏着剂；聚胺基甲酸乙酯系的干层合用接着剂；合成橡胶系接着剂；环氧系接着剂等。所述偏光板较佳为含有自反射防止层及防眩层的至少1种的层，且设置于与偏光子相反侧的保护薄膜面的外侧为佳。
