液晶面板的暗点修复方法及液晶面板
本发明涉及液晶显示技术领域， 尤其涉及- 法.及液晶面板 0
液晶显示器具有机身薄、 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器大部分为背光型液晶显示器， 其包括液晶面 板及背光模组 ( backlight module ) 。 液晶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， 并在两片玻璃基板上施加驱动电压来控制液 晶分子的旋转方向， 以将背光模组的光线折射出来产生画面。 由于液晶面 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， 因此， 背 光模组成为液晶显示器的关键零组件之一。 背光模组依照光源入射位置的 不同分成侧入式背光模组与直下式背光模组两种。 直下式背光模组是将发 光光源例如 CCFL(Cold Cathode Fluorescent Lam , 阴极萤光灯管）或 LED(Light Emitting Diode, 发光二极管)设置在液晶面板后方， 直接形成面 光源提供给液晶面板。 而侧入式背光模组是将背光源 LED 灯条 ( Lightbar )设于液晶面板侧后方的背板边缘， LED 灯条-发出的光线从导 光 ( LGP, Light Guide Plate )一侧的入光面进入导光板， 经反.射和扩散 后从导光板出光面射出， 在经由光学膜片组， 以形成面光源提供给液晶显 示面板。
为了提高大视角的显示品质， 即使斜视角与正视角的颜色一致性好， 液晶面板的像素结构通常会釆用一种称作电荷分享型的像素结构 （ charge- share pixel ) ， 如图 1 所示， 该电荷分享型的像素结构主要是将一主像素 ( Main Pixel ) 分割为第一子像素 ( Sub Pixel ) 100与第二子像素 200两部 分， 其中第一子像素 100 包括一连接至第一栅极线的第一薄膜晶体管 T100, 第二子像素 200 包括一连接至第一柵极线的第二薄膜晶体 T200及 一分别连接至第二薄膜晶体 T200 与第二栅极线的第三薄膜晶体管 T300。 当第一薄膜晶体管 T100 与第二薄膜晶体管 Τ200 通过第一柵极线输入控制 信号而同时被开启时， 第一子像素 100 的液晶电容 Ckj G。与第二子像素 200 的液晶电容 Cjc2。。具有相同的灰阶电压； 随后第三薄膜晶体管 T300 通过第 二棚 _极线输入控制信号而被开启， 因为第一子像素 100的液晶电容 Ck l00与 分压电容 Ccsl。。、 Ccs2。G之间的电荷分享， 使得第一子像素 100 的液晶电容 CiCiG。具有不同于第二子像素 200的液晶电容 Ck2G。的灰阶电压， 进而改善斜 视角的色偏现象， 提高大视角的显示品质。
现有的技术水平， 液晶面板不可避免地会存在一个或数个有缺陷的主 像素。 为了提高液晶面板的良率， 就需要对该些有缺陷的主像素进行暗点 修复， 而现有的暗点修复方法是将第一薄膜晶体管 T100的源极 ( Source ) 的接线、 漏极（Drain ) 的接线及第二薄膜晶体管 T200的漏极（Drain ) 的 接线切断 （图 i 中的 X 所示） ， 同时将主像素的透明导电薄膜 （氧化铟 锡、 ITC Indium tin oxide )和公共电极 ( Com线） 焊接短.路（如图 1 中 粗黑线所示） ， 从而将有缺陷的主像素修复成常暗状态， 提升液晶面板的 良率。 利用该方法对存在缺陷的主像素进行暗点修复費时较长， 所需的修 补工具设备较多， 会导致产能降低， 增加生产成本。 发明内容
本发明的目的在于提供一种液晶面板的暗点修复方法， 通过将具有亮 点缺陷的主像素的分压电容的上下两层金属层焊接短路来实现暗点修复， 该方法操作简单， 可以节省修补时间， 减少修补工具， 提高产能， 降低了 生产成本。
