Abstract

本发明提供一种PDLC显示装置的制作方法及PDLC显示装置。本发明的PDLC显示装置的制作方法，通过黑色矩阵与基板围成数个像素凹槽，并向数个像素凹槽内分别填充聚合物分散液晶与红色量子点的混合物、聚合物分散液晶与绿色量子点的混合物、及聚合物分散液晶，制成聚合物分散液晶基板，并贴合阵列基板，安装蓝光背光模组，从而制得PDLC显示装置；消除了漏光和混色现象，同时节省了配向层和偏光片的制程，提高了生产效率，降低了生产成本。本发明的PDLC显示装置，采用上述方法制得，至少具有红、绿、蓝及模糊四种显示效果，可用于特殊需求的场所，并消除了漏光和混色现象，同时无需设置配向层和偏光片，生产效率较高，生产成本较低。

Description

PDLC显示装置的制作方法及PDLC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PDLC显示装置的制作方法及PDLC显示装置。
背景技术
薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)包含彩色滤光片基板(Color Filter Substrate，CF Substrate)和薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFT Substrate)，基板相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。液晶显示器是通过电场对液晶分子取向的控制，改变光的偏振状态，并藉由偏光板实现光路的穿透与阻挡，实现显示的目的。
可以说，当前不论是大中小尺寸的显示器，均被LCD占据着绝对的市场。而在当前的LCD应用市场中，可用于大型商场、超市、酒店大堂、影院、教育、医疗以及其它人流汇集的公共场所的终端显示设备得到了越来越多的需求和应用，其正以每年30％以上的速度增长着。
另一方面，聚合物分散液晶(Polymer Dispersed Liquid Crystal，PDLC)作为液晶调光阀，近年已被广泛关注和使用。其是将低分子液晶与预聚物相混合，在一定条件下经聚合反应，形成微米级的液晶微滴均匀地分散在高分子网络中，再利用液晶分子的介电各向异性获得具有电光响应特性的材料，它主要工作在散射态和透明态之间并具有一定的灰度。聚合物分散型液晶显示器具有很多优点，例如不需偏振片和取向层，制备工艺简单，易于制成大面积柔性显示器等,目前已在光学调制器、热敏及压敏器件、电控玻璃、光阀、投影显示、电子书等方面获得广泛应用。其工作原理是在无外加电压的情形下，膜间不能形成有规律的电场，液晶微粒的光轴取向随机，呈现无序状态，其有效折射率n0不与聚合物的折射率np匹配。入射光线被强烈散射，薄膜呈不透明或半透明状。施加了外电压，液晶微粒的光轴垂直于薄膜表面排列，即与电场方向一致。微粒之寻常光折射率与聚合物的折射率基本匹配，无明显介面，构成了一基本均匀的介质，所以入射光不会发生散射，薄膜呈透明状。因此，在外加电场的驱动下，PDLC具备光开关特性，而且透明程度还会随着施加电压的增大而沿一定曲线式的提高。
同样，量子点作为新兴的显示器用材料，已经得到了广泛的认可和关注。量子点(quantum dot)是准零维(quasi-zero-dimensional)的纳米材料，由少量的原子所构成。粗略地说，量子点三个维度的尺寸都在100纳米(nm)以下，外观恰似一极小的点状物，其内部电子在各方向上的运动都受到局限，所以量子限域效应(quantum confinement effect)特别显著。其具有激发光谱宽且连续分布，而发射光谱窄而对称，颜色可调，光化学稳定性高，荧光寿命长等优越的特性，是一种理想的发光材料。当前量子点根据能量的获得方式不同而主要有两类，其一为光致发光，其二为电致发光。量子点发光颜色是通过量子点的尺寸效应，即通过控制量子点的形状、结构和尺寸，以调节其能隙宽度、激子束缚能的大小以及激子的能量蓝移等电子状态。
