摘要：
This investigation elucidates the transient behavior associated with switching between two stable states of a bistable chiral-tilted homeotropic nematic liquid crystal device. Experimental results reveal that the applied pulse voltages and durations not only determine the final states but are interestingly related to the relaxation time. When a suitable pulse voltage is applied, the minimum relaxation time can be obtained by adjusting the pulse duration. Analyzing the hydrodynamic behavior of the liquid crystal directors explicates the switching mechanism and relaxation processes. The principles that underlie the design of the waveforms to have the minimum relaxation time are obtained. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2993742]
