Description

偏光与彩色滤光功能整合膜的制备方法及液晶显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种偏光与彩色滤光功能整合膜的制备方法及含有该偏光与彩色滤光功能整合膜的液晶显示面板。
背景技术
液晶显示装置(LCD，Liquid Crystal Display)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括液晶显示面板及背光模组(backlight module)。通常液晶显示面板由彩膜基板(CF，Color Filter)、薄膜晶体管基板(TFT，Thin Film Transistor)、夹于彩膜基板与薄膜晶体管基板之间的液晶(LC，Liquid Crystal)及密封胶框(Sealant)组成；其成型工艺一般包括：前段阵列(Array)制程(薄膜、黄光、蚀刻及剥膜)、中段成盒(Cell)制程(薄膜晶体管基板与彩色滤光膜基板贴合)及后段模组组装制程(驱动电路(IC)与印刷电路板压合)。其中，前段阵列(Array)制程主要是形成薄膜晶体管基板，以便于控制液晶分子的运动；中段成盒(Cell)制程主要是在薄膜晶体管基板与彩色滤光膜基板之间添加液晶；后段模组组装制程主要是驱动电路压合与印刷电路板的整合，进而驱动液晶分子转动，显示图像。
液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，通过玻璃基板通电与否来控制液晶分子取向，改变背光模组的光线的偏振状态，并藉由液晶显示面板两侧设置的偏光板实现光路的穿透与阻挡，达到控制透光量的目的；通过RGB彩色光阻层将透过液晶层的光线进行过滤吸收，使得每个像素的光在射出后都是由三原色(RGB)构成，不同的像素对应发出不同颜色的光，利用空间混色原理，从而实现全彩显示。可见，偏振光和RGB三原色是其显示原理得以实现最重要的两个要素。
现在常用的偏光片只具有偏光的功能，主要有碘系和染料系，其制作原理为将聚乙烯醇(polyvinyl alcohol，PVA)等高分子膜浸泡于含多价碘离子或偏光染料的溶液中，再将PVA高分子以单一轴方向拉伸；PVA分子受外力拉伸后会在一个方向上排列，促使吸附在PVA分子上的碘分子或染料分子和PVA分子同方向排列；拉伸后的细长碘分子或染料分子会吸收平行于碘分子长轴方向振动的光，透过垂直于碘分子长轴方向振动的光，即 得到能够形成偏振光的偏光片。
现有的液晶显示面板，偏振光是由偏光片形成的，而RGB三原色则由RGB彩色光阻层提供，需要使用上下两片偏光片，TFT基板或CF基板上需要设置RGB彩色光阻层，结构及制程复杂，制作成本高。
