Structure of Blue Phase III of Cholesteric Liquid Crystals

Structure of blue phase III of cholesteric liquid crystals.

We report large scale simulations of the blue phases of cholesteric liquid crystals. Our results suggest a structure for blue phase III, the blue fog, which has been the subject of a long debate in liquid crystal physics. We propose that blue phase III is an amorphous network of disclination lines, which is thermodynamically and kinetically stabilized over crystalline blue phases at intermediat...

Cholesteric to cholesteric phase transitions in liquid crystals

Numerical calculations of the phase diagram of cubic blue phases in cholesteric liquid crystals.

We study the static properties of cubic blue phases by numerically minimizing the three-dimensional, Landau-de Gennes free energy for a cholesteric liquid crystal close to the isotropic-cholesteric phase transition. Thus we are able to refine the powerful but approximate, semianalytic frameworks that have been used previously. We obtain the equilibrium phase diagram and discuss it in relation t...

Wetting of cholesteric liquid crystals.

We investigate theoretically the wetting properties of cholesteric liquid crystals at a planar substrate. If the properties of substrate and of the interface are such that the cholesteric layers are not distorted, the wetting properties are similar to those of a nematic liquid crystal. If, on the other hand, the anchoring conditions force the distortion of the liquid crystal layers the wetting ...

Blue-Phase Liquid Crystals for Projection Displays

A projection display using blue-phase liquid crystal (BPLC) is proposed. The fast-response BPLC enables field sequential projection display with suppressed color breakup. Methods for reducing the operating voltage are also discussed. Author
