摘要
在HAN液晶盒撤掉外加电压的过程 (即弛豫过程)中, 假定电压的开关时间为有限的, 把电压处理为时间的指数衰减函数。在这一假定下, 对撤掉外加电压后HAN液晶盒中指向矢的分布情况进行研究, 得到了对HAN液晶盒的弛豫过程有影响的电压开关时间的范围。
Abstract
In the process of moving the voltage applied on hybrid aligned nematic liquid crystal cell (i.e. relaxation process), switching time of voltage is assumed finite, and then the voltage in the relaxation process is handled as exponential attenuation function of time. Based on above assumption, the distribution of the director in hybrid aligned nematic liquid crystal cell is analyzed by numerical simulation and this paper get the range of switching time impacting on the relaxation process.
