下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
发光二极管（Light Emitting Diode，LED），是一种固态的半导体器件，它可以直接把电转化为光。 LED的内在特征决定了它是最理想的光源去代替传统的光源，它有着广泛的用途。
薄膜晶体管（Thin-film transistor，TFT）是场效应晶体管的种类之一，大略的制作方式是在基板上沉积各种不同的薄膜，如半导体主动层、介电层和金属电极层。薄膜晶体管对显示器件的工作性能具有十分重要的作用。
彩色滤光片（Color filter，CF）是一种表现颜色的光学滤光片，它可以精确选择欲通过的小范围波段光波，而反射掉其他不希望通过的波段。彩色滤光片通常安装在光源的前方，使人眼可以接收到饱和的某个颜色光线。有红外滤光片，绿色，蓝色等。
背光模组（Back Light Unit ，BLU）为液晶显示器面板的关键零组件之一。功能在于供应充足的亮度与分布均匀的光源，使其能正常显示影像。
液晶显示器（Liquid Crystal Display，LCD）。如图1所示，目前，LCD 的构造是在两片平行的玻璃基板当中放置液晶盒，下基板玻璃上设置TFT，即形成TFT基板，上基板玻璃上设置彩色滤光片，即形成CF基板，通过TFT基板上的信号与电压改变来控制液晶分子的转动方向，从而达到控制每个像素点偏振光出射与否而达到显示目的。但是，在现有的LCD显示产品中，发光二极管(Light Emitting Diode，LED)尺寸通常在毫米级，每颗LED发光的照射区面积也比较大，且受限于分区数。所以，目前的LCD产品的光源分区数量难以实现大幅提高，对比度和暗态显示效果不佳。
本发明实施例中提供一种液晶显示模组，该液晶显示模组包括：该液晶显示模组包括背光模组及设于该背光模组上方的液晶显示面板，该液晶显示面板包括三层显示基板和两层液晶单元，该三层显示单元和所述两层液晶单元交替设置。
本发明实施例中液晶显示模组包括背光模组及设于该背光模组上方的液晶显示面板，液晶显示面板包括三层显示基板和两层液晶单元，三层显示单元和两层液晶单元交替设置，当背光模组背光源点亮时，通过对第一层液晶的控制，可使光线通过或被阻挡, 从而使通过第一层显示单元的光线实现像素级(微米级) 的细化，提升了液晶显示模组的对比度及暗态品位。
进一步的，该三层显示基板包括两层薄膜晶体管TFT阵列基板和一层彩色滤光片CF基板。进一步的，如图2所示，为本发明实施例中提供的一个液晶显示模组的实施例，该三层显示基板包括第一TFT阵列基板、第二TFT阵列基板和CF基板，该两层液晶单元包括第一液晶层以及第二液晶层，该第一液晶层设于该第一TFT阵列基板与第二TFT阵列基板之间，该第二液晶层设于第二TFT阵列基板与CF基板之间，即每两层显示单元之间填充液晶。进一步的，该第一液晶层和该第二液晶层两侧用框胶密封。
本发明实施例中，该第一TFT阵列基板可以和第二TFT阵列基板中的像素对齐，通过第一TFT阵列基板对光线的细化及第一TFT阵列基板与第二TFT阵列基板的精准对位，最终透过与CF基板的光线改变为以像素为单位进行显示，从而大幅提升了LCD的对比度和暗态显示效果。
进一步的，该液晶显示面板还可以包括贴附于该CF基板上远离第二TFT阵列基板一侧的上偏光片及贴附于第一TFT阵列基板的下表面上的下偏光片。
其中，该第一TFT阵列基板可以包括靠近所述第二TFT阵列基板一侧的上表面以及远离所述第二TFT阵列基板一侧的下表面，该第一TFT阵列基板的下表面上直接制作形成有金属遮光层，如由Al-Nd、Mo、Cr、CrOx、Ta、MoW、Cu、Al等材料制作而成的金属遮光层。进一步的，金属遮光层位于下偏光片的外围。
在本发明中，金属遮光层是直接制作形成在第一TFT阵列基板的下表面上，且与第一TFT阵列基板为一体。本发明摒弃了传统的胶带贴附方式，而是通过制程直接将金属遮光层制作在第一TFT阵列基板的下表面上，金属遮光层与第一TFT阵列基板形成为一体，使得第一TFT阵列基板本身即自带有用于遮光功能的金属遮光层，从而无需在后续组装时再另外贴附不透光胶带。
