A Monte Carlo Simulation of a Twisted Nematic Liquid Crystal Display

Liquid Crystal Lattice Models Ii. Confined Systems

Monte Carlo simulations of lattice spin models represent a powerful method for the investigation of confined nematic liquid crystals and allow a study of the molecular organization and thermodynamics of these systems. Here some models of confined liquid crystals, such as polymer dispersed liquid crystals, twisted nematic, in-plane switching liquid crystal displays and hybrid aligned films are d...

Computer Simulations of Nematic Displays

Monte Carlo simulations of electroptical devices based on a nematic Lebwohl-Lasher liquid crystal model with suitable boundary conditions are presented. The simplicity of the model allows an investigation of various effects like the influence of an external field strength and that of anchoring at the oriented surfaces of the display cell. Moreover suitable order parameters are introduced to fac...

Reflective twisted nematic liquid crystal displays. II. Elimination of retardation film and rear polarizer

Reflective twisted nematic liquid crystal displays consisting of just one input polarizer, a liquid crystal cell, and a rear reflector are discussed. We first show that all such display modes reported in the literature can be depicted systematically in a series of parameter space diagrams. Then by making use of such diagrams as a guide, we show that other new high quality reflective display mod...

Columnar liquid crystals formed by bowl–shaped mesogens. A Monte Carlo study

We have investigated the stacking of model bowlic mesogens, and the nematic and columnar liquid crystal phases they form upon cooling– down from an isotropic liquid. Starting from an attractive–repulsive interaction obtained generalising the Gay–Berne pair potential to bowlic shapes, we have performed extensive off–lattice Monte Carlo NPT computer simulations of samples of various sizes: N = 10...
