3 dimensional model of LCD pixel with TFT

Detailed LCD modeling in 3 dimensions

• Import of existing CAD data (e.g. GDS2) and post-processing for definition of material properties, alignment parameters and initial director configurations;
• easy definition and creation of models by integrated 3D editor that replicates a real mask deposition process;
• advanced meshing generator for minimum meshing time;
• self-adaptive tetrahedral mesh for accurate results with minimum number of nodes;
• reduced calculation times by mesh adaption to local geometries;
• user-adjustable meshing options from fast to accurate;
• initial relaxation of LC director;
• periodic boundary conditions;

• calculation of director configuration over subpixel area or a multitude of pixels;
• calculation of transmittance and reflectance over subpixel area or a multitude of pixels;
• evaluation of areas of interest for e.g. average luminance;
• calculation of stray capacitance between all electrodes;
• polarization state analysis, representation via Poincare Sphere or Stokes Parameters.

Typical applications for this comprehensive way of modeling include complex TFT-LCDs with MVA, PVA, S-IPS, FFS, TN, OCB etc..
