Domains and domain switching in antiferroelectric liquid crystal displays

Experimental Investigation of Domain Wall Motion and Switching in Antiferroelectric Liquid Crystal Displays

“…The wall that separates both domains will move in the direction that favours this state that corresponds with an absolute energy minimum. In [3] it is explained that there exists a threshold value V t ( fig. 1) where both local energy minima are equal, and where the wall motion stops.…”

“…1) where both local energy minima are equal, and where the wall motion stops. According to the simple model used in [3], this V t is independent of the surface anchoring constant γ, so that in principle, even with a statistically varying γ, all domain wall motion could be stopped. However one should keep in mind that during the holding period the voltage over the pixel is disturbed by the cross talk signals.…”

“…a bright domain grows at the expense of a neighbouring dark domain or vice versa. In previous publications we described the theory and simulation results of homogeneous switching [2] and of domain wall motion [3]. In the present paper these two ways of switching and their relative importance are investigated for the specific case of an antiferroelectric display, which is addressed by the addressing scheme of the full color prototype of Nippondenso [4].…”

Antiferroelectric polarization switching and dynamic scaling of energy storage: A Monte Carlo simulation

“…On the other hand, there have been only a few simulation reports on the polarization switching of AFE materials. 29,30 In addition, no simulation on the scaling studies of AFE materials has been available to the best of our knowledge. We are only aware of the work of Misirlioglu et al which deals with a two-dimensional Ising model to simulate the FE-AFE hysteresis.…”
