Description

曲面双面液晶显示器 技术领域
本发明涉及液晶显示领域, 尤其涉及一种曲面双面液晶显示器。 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, 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。 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 下式背光模组是将背光源例如 CCFL(Cold Cathode Fluorescent Lamp, 阴极 萤光灯管)或 LED(Light Emitting Diode发光二极管)光源设置在液晶面板后 方, 光线经扩散板均匀化后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。
近年来, 随着液晶显示技术的发展, 各大厂商陆续推出了曲面的液晶 显示器, 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, 会让用户的观赏距离拉长, 达到更好的观赏体验, 目前常见的曲 面液晶显示器多为曲面单面液晶显示器。 在商用显示器领域, 双面显示器 的应用也越来越广泛, 目前常见的双面显示器多为平面双面显示器, 对市 场的吸引力不是很大。 曲面双面液晶显示器相比平面双面显示器, 有着很 大的优势: 如提高对市场及消费者的吸引力、 形成品牌的差异化等。
