Description

阵列基板及该阵列基板的断线修补方法 技术领域
本发明涉及显示技术领域,尤其涉及一种阵列基板及该阵列基板的断线修补方法。
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器大部分为背光型液晶显示器,其包括壳体、设于壳体内的液晶显示面板及设于壳体内的背光模组。液晶显示面板是液晶显示器的主要组件,但液晶显示面板本身不发光,需要借由背光模组提供的光源来正常显示影像。
通常液晶显示面板由两片玻璃基板贴合而成,且在两片玻璃基板之间灌入液晶,分别在两片玻璃基板的相对内侧设置像素电极、共用电极线,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。
在液晶面板中,液晶的像素电极电压主要是通过薄膜晶体管(Thin Film Transistor,TFT)开关进行控制的。在TFT开关组件中,尤其是超高分辨率的液晶面板,提供图像信号的数据线线宽很窄,在制造工艺过程中容易发生断线,需要采用激光进行断线修补动作。在广视角的液晶面板技术上,为了提高开开口率及液晶的响应速度,通常会在液晶面板的阵列基板上制作有机层如色阻层或平坦层。当数据线产生断线缺陷时,由于有机层的厚度较大,无法直接进行断线修补,需要先用一种镭射进行去除有机层动作,然后再进行熔接补线动作。因此,镭射能量能耗大,耗费时间长,采用镭射去除后接触面凹凸不平,容易导致接触不良,进而直接影响产品的良率。
