Description

背光模组 技术领域
本发明涉及一种背光模组， 尤其涉及一种利于窄边框化的背光模组。 背景技术
液晶显示装置（LCD, Liquid Crystal Display )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装置大部分 为背光型液晶显示装置， 其包括液晶显示面板及背光模组 （backlight module ) 。 液晶显示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， 两片玻璃基板中间有许多垂直和水平的细小电线， 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。 由于液 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， 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 CCFL(Cold Cathode Fluorescent Lamp, 阴极萤光灯管) 或 LED(Light Emitting Diode, 发光二极管)设置在液晶显示面板后方， 直 接形成面光源提供给液晶显示面板。 而侧入式背光模组是将背光源 LED 灯条（Light bar )设于液晶显示面板侧后方的背板边缘， LED 灯条发出的 光线从导光板（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。
请参阅图 1 , 在现有的背光模组设计中， 通常采用铆柱 200 来固定导 光板 300、 光学膜片组 400等光学组件， 但是因为铆柱 200用于铆接的部 分尺寸较大， 因此对空间的需求也较大， 即需要在铆柱 200与背板 500的 侧板 502之间预留一定的间隙 L, 这对背光模组的窄边框化设计产生了不 良影响。
而且在进行一般的窄边框设计时， 由于胶框对光学膜片组的限制作用 减小， 容易造成光学膜片组脱落， 造成光学品级的下降。 发明内容
