| 摘 要： | 提出将电路级模拟器扩展应用到二维铁电液晶(FLC)的光电混合系统。依照铁电液晶的理论模型建立等效电路,通过调整时序脉冲及驱动源波形,灵活地控制晶胞厚度、面积、粘滞系数、入射偏振角和自发极化强度等典型参数,实现了开关响应特性的动态模拟。比较铁电液晶与扭曲向列型液晶(TN)显示盒的差异。结果表明,该技术方法不仅适用于FLC结构参数指标的优化,而且对于其它集成光学器件的仿真技术研究也是一种有益地探索。

Study on structure parameter of two-dimension ferroelectric liquid crystal by electronic model |
| |
| Abstract: | In order to optimize the overall performance of a two-dimension ferroe lectric liquid crystal (FLC) device and optoelectronic-system design, an approa c h that simulates the FLC in its electrical environment seems more appropriate. T he cell separation and area, input polariser orientation and rotational viscosit y in addition to the spontaneous polarization are discussed. Relations between this parameters and electro-optic response are simulated using Pspice electron i c model in various conditions. The differences between FLC and conventional TN c ases are compared. The results well show simulation and experiment has excellen t agreement. With additions to the model, it is expected to be able to simulate optoelectronic commix device. |
