研究了多方向摩擦均匀液晶盒的取向特性。LC分子沿两个不同摩擦方向之间的轴沿着排列。摩擦强度、液晶盒厚度和环境温度显著影响液晶分子的最终取向。液晶分子的取向和多向摩擦单元的透射率可以根据环境温度来控制。提出了一个假设基片沿沿着不同摩擦方向具有不同沟槽密度的模型。液晶分子的弹性常数和粘度是影响液晶分子取向的关键因素。
The alignment characteristics of the homogeneous liquid-crystal (LC) cell rubbed multidirectionally were examined. LC molecules align along an axis between two different rubbing directions. The rubbing strength, cell thickness, and ambient temperature markedly influence the final orientation of the LC molecules. The orientation of the LC molecules and the transmission of a multidirectionally rubbed cell can be controlled according to the ambient temperature. A model that assumes substrate with various groove densities along various rubbing directions is presented. The elastic constant and the viscosity of the LC molecules are found to be the key factors that influence the orientation of the LC molecules.
