Abstract

Description

COA型液晶显示面板的制作方法及COA型液晶显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种COA型液晶显示面板的制作方法及COA型液晶显示面板。
背景技术
随着显示技术的发展，液晶显示器(Liquid Crystal Display，LCD)等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。
现有市场上的液晶显示装置大部分为背光型液晶显示器，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(CF，Color Filter)基板、薄膜晶体管(TFT，Thin Film Transistor)基板、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。然而，这种结构的液晶显示面板经常会出现彩膜基板与薄膜晶体管基板对位不良的问题，进而造成像素漏光或开口率低等问题。为解决上述问题，产生了COA结构的液晶显示面板，COA(Color Filter on Array)技术是将彩色滤光层制备在TFT基板上的技术，以形成彩色滤光片，因为COA结构的液晶显示面板不存在彩膜基板与阵列基板的对位问题，所以可以降低显示面板制备过程中对盒制程的难度，避免了对盒时的误差，因此黑色矩阵可以设计为窄线宽，提高了开口率。
液晶显示面板的显示原理通常为：背光通过下偏光片，形成偏振方向与下偏光片穿透轴平行的偏振光。偏振光通过RGB彩色滤光片后产生R，G，B三色的偏振光。R，G，B三色偏振光经过液晶层调整偏正方向，然后通过上偏光片(COA结构的液晶显示面板)；或者，R，G，B三色偏振光先通过液晶层，然后经过RGB彩色滤光片层产生R，G，B三色的偏振光，最后经过上偏光片出光(一般结构的液晶显示面板)。无论哪一种结构的液晶显示面板，液晶层在其中起到控制光量通过的阀门的作用，其显示原理得以实现的最重要的两个要素为：1、偏振光；2、RGB三原色。
目前，因为量子点(QD，Quantum-Dot)能够在背光的激发下发出的光具有波长窄(半波峰小)，色彩鲜艳(色浓度高)的特点，很多技术专注于将量子点应用在液晶显示面板中，以提高显示面板的色饱和度。与量子 点不同的是，量子棒(QR，Quantum-Rod)发出的激发光可以是偏振光，并且，通过控制量子棒的直径，可以控制从量子棒发出的光的波长。
