具有光伏电池的液晶显示模组的制作方法及其制得的液晶显示模组
技术领域
本发明涉及液晶显示领域， 尤其涉及一种具有光伏电池的液晶显示模 组的制作方法及其制得的液晶显示模组。 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， 通过玻璃基板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 ) ― 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显示面板。 然而， 背光源发出的光只有 6%左右可以透过液晶显示面板， 这就造成大量光能被浪费。
通常液晶显示面板由彩膜基板 ( CF , Color Filter ) 、 薄膜晶体管基板
( TFT , Thin Film Transistor) , 夹于彩膜基板与薄膜晶体管基板之间的液晶 ( LC , Liquid Crystal )及密封胶（Sealant )组成， 其成型工艺一般包括： 前段阵列 （Array )制程（薄膜、 黄光、 蚀刻及剥膜） 、 中段成盒（Cell ) 制程（ TFT基板与 CF基板贴合 )及后段模组组装制程（驱动 IC与印刷电 路板压合） 。 其中， 前段 Array制程主要是形成 TFT基板， 以便于控制液 晶分子的运动； 中段 Cell制程主要是在 TFT基板与 CF基板之间添加液 晶； 后段模组组装制程主要是驱动 IC压合与印刷电路板的整合， 进而驱 动液晶分子转动， 显示图像。
现有的 TFT基板的第一与第二金属电极， 对背光模组的光有一定的遮 挡， 使得背光模组所发出的光线不能完全被液晶显示面板所利用， 造成了 光能损耗。
光伏电池是通过光电效应或者光化学效应直接把光能转化成电能的装 置， 为了提高液晶显示装置中的背光源的光的利用率， 本领域技术人员在 液晶显示面板中加入光伏电池， 该光伏电池吸收多余的光能， 并将光能转 化为电能， 为液晶显示面板的元件或配件供电， 充分利用背光源所发出的 光能， 节省了对外部电能的消耗。
然而， 现有技术是将制作好的光伏电池集成于液晶显示面板中， 制程 较为复杂， 生产周期也较长， 进而增加了生产成本， 且该光伏电池容易受 到外界水汽、 氧气等侵蚀、 氧化， 导致光伏电池使用寿命低。 发明内容
