Effect of Dielectric Anisotropy on Optoelectric Characteristics of Ferroelectric Liquid Crystal

  • 摘要: 提出了一种描述铁电液晶(FLC)介电各向异性的电路模型.分析了FLC介电各向异性对开关响应时间、特征时间、特征电压和极化反转电流的作用,以及铁电扭矩和介电扭矩对光透射率的影响。模拟分析显示,延迟时间随驱动电压幅度变化存在最小值,特征时间(特征电压)随二轴参量的提高而增加(减小).随二轴参量增大,介电扭矩的贡献将超过铁电扭矩;相应的极化反转电流由双极性转变为单极性;透射率无"明态"和"暗态"的交替,且峰值逐步降低.
