Description

背光模组 技术领域
本发明涉及平面显示领域， 尤其涉及一种背光模组。 背景技术
液晶显示装置 （ Liquid Crystal Display, LCD )具有机身薄、 省电、 无 辐射等众多优点， 得到了广泛的应用， 如移动电话、 个人数字助理 ( PDA ) 、 数字相机、 计算机屏幕或笔记本电脑屏幕等。
现有市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 ) 、 一薄膜晶体管阵列基板 ( 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 )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， 再经由光学膜片组， 以形成面光源提供给 液晶面板。
随着社会的发展， 现在用户对液晶显示装所显示的画面的质量要求越 来越高， 为了提升画面的色彩饱和度， 通过改善背光单元中灯条的色度， 就可以提升画面的色彩饱和度， 现有的技术是在背光模组中上安装量子 条。
请参阅图 1和图 2， 图 1为量子条的立体结构示意图， 图 2为量子条 的剖面结构示意图， 如图 2所示， 量子条包括有效区 100与玻璃封装外围 300， 量子条横截面呈椭圓形， 因此在背光模组组装过程及运输过程中容 易产生量子条翻转， 导致出现光效果异常的现象， 同时由于量子条是玻璃 封装处理， 容易破损， 因此在模组结构设计中需要设计量子条固定支架， 起到固定量子条、 防止量子条弯曲偏转、 对量子条进行隔热保护等成为一 种必须。 发明内容
