Description

曲面液晶显示装置 技术领域
本发明涉及液晶显示领域， 尤其涉及一种曲面液晶显示装置。 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。 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。
近年来， 各大厂商陆续的推出了曲面的液晶显示装置， 整体而言， 曲 面的液晶显示装置从边缘到边缘都能提供最佳的观看效果， 而普通的液晶 显示装置在屏幕边缘方面的呈现能力一直相对不太理想。 曲面液晶显示装 置整片屏幕朝用户方向包围的弧形设计， 可提供宽阔的全景影像效果， 不 论是在屏幕中央还是边缘四周， 都能够带来同样的视觉享受， 并且在近距 离观看时还减少了离轴观看的失真度。 此外， 曲面的液晶显示装置会让用 户的观赏距离拉长， 达到更好的观赏体验。 因此， 相比于普通的液晶显示 装置， 曲面液晶显示装置有着很大的优势： 1、 品牌的差异化； 2、 更宽广 的可视角度； 3、 减少近距离观看的失真度。
请参阅图 1， 为现有的一种曲面液晶显示装置， 其包括： 背光模组 100、 设于背光模组 100上的胶框 300、 设于胶框 300 内的液晶显示面板 500及设于液晶显示面板 500上的前框 700， 所述背光模组 100的导光板 102呈曲面设置， 而背光模组 100的背光源 104需要对应导光板 102的入 光面， 这就使得固定背光源 104的散热板 106呈一定的斜度设置， 而为了 配合曲面液晶显示装置的整体结构， 前框 700的侧板 702需要竖直设置， 这就导致侧板 702与散热板 106之间存在一个很大的间隙 762， 不利于实 现曲面液晶显示装置的窄边框化。 发明内容

所述背板 22由铁钣金制成， 其厚度为 0.8~lmm。
所述散热板 28由铝钣金制成。
所述背光模组 2还包括设于弧形导光板 24朝向背板 22的底面的底反 射片 23及位于弧形导光板 24上方且放置于胶框 4内的光学膜片组 25。
由于前框 8直接形成朝向安装部 284的连接部 842， 省略了现有的背 板的侧板， 缩短了前框 8的侧板 84与弧形导光板 24之间的间距， 进而可 以降低前框 8 的前板 82 的宽度， 实现曲面液晶显示装置的窄边框化。 以 本实施例中背板 22由厚度为 0.8~lmm的铁钣金制成为例， 该前框 8的前 板 82的宽度可以降低 0.8~lmm。
同时， 由于前框 8的侧板 84直接锁合于散热板 28的安装部 284上， 胶框 4一端部 42抵靠所述安装部 284背对背光源 26的外侧面， 且位于连 接部 842—侧， 这就进一步缩短了前框 8的侧板 84与弧形导光板 24之间 的间距， 从而实现了曲面液晶显示装置的窄边框化。
综上所述， 本发明的曲面液晶显示装置， 通过在前框的侧板上设置朝 向散热板的安装部凸出的连接部， 并通过该连接部锁合于散热板， 从而将 前框与散热板连接在一起， 不需要在该锁合位置设置背板的侧板， 并有效 缩短前框与弧形导光板之间的间距， 利于实现曲面液晶显示装置的窄边框 化。
以上所述， 对于本领域的普通技术人员来说， 可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形， 而所有这些改变和变形 都应属于本发明权利要求的保护范围。
