Pretilt Angle Effects on Liquid Crystal Response Time

Properties of Nematic Liquid Crystals Doped with CdSe/ZnS Semiconductor Nanoparticales

“…% (табл.). Увеличение начального угла наклона директора является одним из факторов, влияющим на уменьшение времени отклика ЖК [38]. Одновременно с увеличением угла  p уменьшалось и пороговое напряжение, определяемое экстраполяцией зависимости фазовой задержки от напряжения [29].…”

Accurate and Efficient Modeling to Calculate the Voltage Dependence of Liquid Crystal-Based Reflectarray Cells

“…Firstly, accurate modeling of the intermediate biasing states in LC's that takes into account the anisotropy and inhomogeneity in the direction of the biasing field (longitudinal inhomogeneity) is applied and evaluated for first time for reflectarray cells. The inhomogeneous permittivity tensor is obtained for each voltage from the solution of the elastic problem related to the biasing of the LC [9]- [14]. Then, a stratified medium, which is derived from the segmentation of the corresponding tensor at each voltage, is used to model the LC and to calculate the reflection coefficient by using an electromagnetic simulator based on Spectral-Domain Method of Moments (SD-MoM), which in turns allows the extraction of the voltage dependence of the reflectarray cells.…”

Anchoring energy enhancement and pretilt angle control of liquid crystal alignment on polymerized surfaces

“…This indicates that smaller pretilt angle or more slanted pretilt angle is generated by polymer protrusions on the substrate surface. 16 Fig. 4(b) shows the simulated V-T curves of VA cells with same pretilt angle (88 • ) but with different anchoring energy.…”
