Liquid crystal director distributions in hybrid aligned nematic cells with strong and weak polar anchoring boundaries are numerically analyzed. The cell can be changed to homogeneous or homeotropic orientation by controlling the anchoring, which have no threshold voltage and driving voltage can be reduced less than 0.5 volt.

 

The degree of isotropy in an elastomer stretched by a microelectromechanical system (MEMS) was perfected from 40.96% to 100%, which was achieved by relocating the applied forces in the MEMS and modifying the shapes of the elastomer. The effectiveness was proven by surface plasmon resonance that filtered purer colors.

 

This study demonstrates a low-voltage tunable photonic bandgap (PBG) device with less deformation in full visible region based on electrospun fibers of ferroelectric liquid crystal doped CLC (FLC-CLC) integrating with electrothermal film heater.

 

We propose dynamic rewritable phase grating based on a polymerized blue phase structure containing azobenzene liquid crystal. The phase grating comprised by periodic blue phase and the isotropic phase region by patterned ultraviolet radiation. Incorporating the reversible photoisomerization of the azobenzene, the device is featured by the optical-patterning and erasure.

 

This study focuses on the influences of light shutter architecture resulted from the adopted polymer networks. The proposed cholesteric liquid crystal (CLC) light shutter can be switched between transparent and scattering states under the illumination of UV lights. The applications of smart windows are also proposed in this study.

 

We propose to incorporate a proper amount of bent-core liquid crystal into rod-like cholesteric liquid crystal and investigate the voltage dependence of electro-optical responses and the formation of various textures. Under suitable voltages, we can get a defect-free uniform lying helix by the voltage-induced dielectric and strong flexoelectric effects.
