现有巿场上的液晶显示装置大部分为背光型液晶显示装置,其包括壳 体、 设于壳体内的液晶面板及设于壳体内的背光模组( Backlight module ) 。 传统的液晶面板的结构是由一彩色滤光片基板( Color Filter )、 ——薄膜晶体管阵歹 [J基板 ( Thin Film Transistor Array Substrate , TFT Array Substrate )以及一配置于两基板间的液晶层( Liquid Crystal Layer )所构成,其工作原理是通过在两片玻璃基板上施加驱动电压来控制 液晶层的液晶分子的旋转,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装置的关键组件之一。 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 是将发光光源例如阴极萤光灯管( Cold Cathode Fluorescent Lamp , CCFL )或发光二极管( Light Emitting Diode , LED )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 ( Light bar )设于液晶面板侧后方的背板边缘处, LED灯条发出的光 线从导光板 ( Light Guide Plate , LGP )—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,再经由光学膜片组,以形成面光源提供给 液晶面板。
