Definitions

  • the present invention relates to the field of display technologies, and in particular, to a method for fabricating a PDLC display device and a PDLC display device.
  • a Thin Film Transistor-Liquid Crystal Display includes a Color Filter Substrate (CF Substrate) and a Thin Film Transistor Substrate (TFT Substrate), and the substrate exists on the opposite side. Transparent electrode.
  • a layer of liquid crystal molecules (LC) is sandwiched between the two substrates. The liquid crystal display controls the orientation of the liquid crystal molecules by the electric field, changes the polarization state of the light, and realizes the purpose of display by the penetration and blocking of the optical path by the polarizing plate.
  • the current large, medium and small size display is occupied by the LCD in an absolute market.
  • terminal display devices that can be used in public places such as large shopping malls, supermarkets, hotel lobbies, theaters, education, medical care, and other crowds are getting more and more demand and application. More than 30% of the speed is growing.
  • PDLC Polymer Dispersed Liquid Crystal
  • the method comprises the steps of: mixing a low molecular liquid crystal with a prepolymer, and polymerizing under certain conditions to form a micron-sized liquid crystal droplet uniformly dispersed in a polymer network, and then using the dielectric anisotropy of the liquid crystal molecule to obtain electro-optic light.
  • the material of the response characteristic which mainly works between the scattering state and the transparent state and has a certain gray scale.
  • the polymer dispersed liquid crystal display has many advantages, such as no need for a polarizing plate and an alignment layer, a simple preparation process, and easy to manufacture a large-area flexible display, etc., and has been in optical modulators, thermal and pressure sensitive devices, electronically controlled glass, Light valves, projection displays, e-books and other aspects have been widely used.
  • the working principle is that in the absence of an applied voltage, a regular electric field cannot be formed between the films, and the optical axis of the liquid crystal particles is randomly oriented and appears disordered, and the effective refractive index n0 does not match the refractive index np of the polymer. The incident light is strongly scattered and the film is opaque or translucent.

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。

步骤2、如图3-图4所示，在所述黑色矩阵11、数个像素凹槽12、及第一基板10上形成整面的公共电极13。
具体地，采用溅射的方式形成整面的公共电极13。
具体地，所述公共电极13为透明电极；优选的，所述公共电极13的材料为氧化铟锡(ITO)或氧化铟锌(IZO)。
步骤3、如图5所示，提供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；以每三个相邻的像素凹槽12作为一个像素单元，分别向所述像素单元中的第一、第二个像素凹槽12内填充聚合物分散液晶和红色量子点的混合物与聚合物分散液晶与绿色量子点的混合物，分别构成红色子像素凹槽121、绿色子像素凹槽122，向所述像素单元中的第三个像素凹槽12内填充聚合物分散液晶，构成蓝色子像素凹槽123，得到聚合物分散液晶基板1。
具体地，所述红色子像素凹槽121中的红色量子点与绿色子像素凹槽122中的绿色量子点分别在蓝光的激发下发出红、绿光；所述蓝色子像素凹槽123中的聚合物分散液晶可以使蓝色背光透过从而显现出蓝色。
具体的，所述聚合物分散液晶基板1中，每个像素单元还可以包括白色子像素凹槽，所述白色子像素凹槽内填充有红光量子点、绿光量子点、及聚合物分散液晶的混合物。
具体的，所述聚合物分散液晶基板1中，每个像素单元还可以包括黄色子像素凹槽，所述黄色子像素凹槽内填充有黄光量子点与聚合物分散液晶的混合物。
具体地，所述聚合物分散液晶与红色量子点的混合物、及聚合物分散液晶与绿色量子点的混合物中，所述红色量子点或绿色量子点与聚合物分散液晶的质量比为5％～10％。
步骤4、如图6-图7所示，提供阵列基板2，所述阵列基板2包括第二基板20、设于第二基板20上的薄膜晶体管层21、及设于所述薄膜晶体管层21上的像素电极层22；所述像素电极层22包括分别与数个像素凹槽12相对应的数个像素电极221。
