本文提出了一种基于纳米粒子掺杂聚合物薄膜生产双液晶（LC）排列配置的方法。实验结果表明，用非偏振紫外光穿过光掩模照射涂覆在具有均匀取向层的基材上的纳米颗粒掺杂预聚物薄膜，引起预聚物聚合，最终分别在未聚合和聚合区域中产生均匀和垂直取向层。均匀（垂直）和混合排列的双液晶排列配置可以通过将处理过的基底与具有均匀（垂直）排列层的另一基底组合来实现。此外，还演示了双液晶配向层在相位光栅和透反射液晶显示器中的应用。
This paper proposes an approach for producing dual liquid crystal (LC) alignment configuration based on nanoparticle-doped polymer films. Experimental results indicate that illuminating a nanoparticle-doped pre-polymer film, coated onto a substrate with a homogeneous alignment layer, with unpolarized UV light through a photomask causes the polymerization of pre-polymer, ultimately generating homogeneous and vertical alignment layers in unpolymerized and polymerized regions, respectively. The dual LC alignment configuration of the homogeneous (vertical) and hybrid alignments can be achieved by combining the treated substrate with another substrate that has a homogeneous (vertical) alignment layer. Additionally, the applications of the dual LC alignment layer in phase gratings and transflective LC displays are demonstrated.
