Implementation of Tensor Model into 3D FEM Simulator for Liquid Crystal Displays
We report our successful implementation of tensor model in three-dimensional finite element method (FEM) simulator for the first to our knowledge. The accuracy of the FEM simulator was verified with the experimental data for the optically compensated bend (OCB) mode. The 3D-FEM tensor-model-based simulation revealed that the spaly-to-bend transition occurs only at 4 V while the vector-mdel based FEM solver provides an erroneous transition voltage of 8 V. The FEM code implemented in this work is based upon the Landau-de Gennes Q tensor model as well as the models of Dickmann and Nakagawa. We thoroughly investigated the moleculardynamic behavior of liquid crystal molecules in the OCB mode in order to understand the physics of operation.
