Description

液晶面板

面板„
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。
为了改善大视角液晶面板显示品质， 行业内一般采用将一个子像素 ( Sub-pixel )分为两个区域， 并将两区域的 V T曲线 (电压—穿透率曲线） 设置不一致， 从而通过两区域的 V T曲线的叠加来改善原本 V-T曲线， 最 终达到改善大视角液晶面板的显示品质。 如图 1 所示， 现有形成两区域不 一致的 V~T曲线的做法是在电容充完电后通过电容輛合使两区域 100、 200 产生电压差异， 最终使两区域 100 , 200 的 V-T 曲线不一致， 从而可以进 行叠加。 但是这种方法需要较大面积去设置耦合电容等电子器件， 这就不 利于像素开口率。 所述开口率是指除去每一个像素的配线部、 晶体管部 (通常采用黑色矩阵隐藏：）后的光线通过部分的面积与每一个像素整体的 面积之间的比例。 发明内容
