Abstract
We investigate how miscellaneous parameters influence the velocity of the disclination line in a bistable chiral splay nematic liquid crystal (BCSN LC) device, using a model derived from the relationship of the free energy loss rate with dissipation energy. The disclination velocity is consistently coupled with the free energy difference between two stable states, rotational viscosity, and damping factor, in which the free energy difference is the most influential. The relationships between the energy difference and the parameters of the BCSN LC device were elucidated by examining the portrait of bistable curves. The calculated velocities of the disclination motion were also confirmed by comparing them with the measured results.
