Abstract

本发明提供一种显示面板及其制作方法,通过在彩膜基板上靠近液晶层的一侧设置与黑色矩阵相对应的矩阵电极,由于矩阵电极与公共电极信号连接,因此矩阵电极和公共电极之间不存在电压差,无论在通电和不通电状态下,位于矩阵电极与阵列基板的公共电极之间的液晶层都不会发生偏转,一直呈不透光状态,使得面板相邻像素之间的光线不会产生干扰,消除了面板的大视角色偏,改善LTPS显示面板的显示品质。

Description

显示面板及其制作方法
技术领域
本发明涉及显示技术领域,尤其涉及一种显示面板及其制作方法。
背景技术
随着显示技术的发展,液晶显示器(LiquidCrystalDisplay,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LTPS显示面板及背光模组(backlightmodule)。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,两片玻璃基板中间有许多垂直和水平的细小电线,通过通电与否来控制液晶分子改变方向,将背光模组的光线折射出来产生画面。
通常液晶显示面板由彩膜(CF,ColorFilter)基板、薄膜晶体管(TFT,ThinFilmTransistor)基板、夹于彩膜基板与薄膜晶体管基板之间的液晶(LC,LiquidCrystal)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(TFT基板与CF基板贴合)及后段模组组装制程(驱动IC与印刷电路板压合)。其中,前段Array制程主要是形成TFT基板,以便于控制液晶分子的运动;中段Cell制程主要是在TFT基板与CF基板之间添加液晶;后段模组组装制程主要是驱动IC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。
低温多晶硅(LowTemperaturePolySilicon,LTPS)是广泛用于中小电子产品中的一种液晶显示技术。传统的非晶硅材料的电子迁移率约0.5-1.0cm2/V.S,而低温多晶硅的电子迁移率可达30-300cm2/V.S。因此,低温多晶硅液晶显示器具有高解析度、反应速度快、高开口率等诸多优点。目前,LTPS显示面板在高端手机、平板电脑上已获得广泛应用,IPHONE6S手机、LGG4手机、KindleFireHdx平板电脑等产品均使用LTPS显示面板。然而,部分LTPS显示面板会出现大视角色偏的情况,用户从较大视角倾斜着看LTPS显示面板时会发现面板的显示偏离了正常的颜色水平。
如图1所示,为现有的LTPS显示面板的结构示意图,所述LTPS显示面板包括相对设置的彩膜基板100与阵列基板200、及夹设于所述彩膜基板100与阵列基板200之间的液晶层300,所述彩膜基板100包括第一衬底基板110、设于所述第一衬底基板110上的黑色矩阵120和彩色光阻层130、以及设于所述彩色光阻层130上的平坦层140;所述阵列基板200包括第二衬底基板210、设于所述第二衬底基板210上的TFT层220、设于所述TFT层220上的像素电极230、设于所述像素电极230上的绝缘层240、及设于所述绝缘层240上的公共电极250,当人眼从较大角度观看显示面板时,从阵列基板200的一个像素单元透过的光会从彩膜基板100中的两个像素单元透出,使人眼感受到色偏。因此,有必要提供一种LTPS显示面板,以解决该技术问题。
发明内容
本发明的目的在于提供一种LTPS显示面板,通过在彩膜基板上靠近液晶层的一侧设置与黑色矩阵相对应的矩阵电极,使得LTPS显示面板中相邻像素之间的光线不会产生干扰,消除了面板的大视角色偏,改善LTPS显示面板的显示品质。
本发明的目的还在于提供一种LTPS显示面板的制作方法,制作方法简单,制得的LTPS显示面板可消除大视角色偏,改善LTPS显示面板的显示品质。
为实现上述目的,本发明提供一种LTPS显示面板,包括相对设置的彩膜基板与阵列基板、及夹设于所述彩膜基板与阵列基板之间的液晶层;
