Description

液晶显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种液晶显示装置。
背景技术
在显示技术领域，液晶显示装置(Liquid Crystal Display，LCD)等平板显示装置已经逐步取代阴极射线管(Cathode Ray Tube，CRT)显示装置。液晶显示装置具有机身薄、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)。通常液晶显示面板由彩膜(Color Filter，CF)基板、薄膜晶体管(Thin Film Transistor，TFT)阵列基板、夹于彩膜基板与薄膜晶体管阵列基板之间的液晶(Liquid Crystal，LC)及密封胶框(Sealant)组成。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，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，再经由光学膜片组，以形成面光源提供给液晶面板。
现有的液晶显示装置不论是采用直下式背光模组或是采用侧入式背光模组，其背光模组是独立于液晶面板设置的，因此设计时需要为背光模组预留一定的空间，使得液晶显示装置需要具有一定的厚度。随着显示技术的不断发展，薄型化的显示装置越来越受到消费者的青睐，传统的液晶显示装置已经无法满足人们对显示装置的薄型化的需求。
