The application of boundary element method to the resistance calculation problem in designing flat panel displays

Abstract

-Several techniques are presented for the efficient resistance calculation of wiring structures in flat panel display (FPD). The techniques are based on two-dimensional boundary element method (BEM), suitable for the geometry characteristics of the FPD structures. With an automatic strategy for boundary element partition and the analytical BEM-coupled approach, the proposed resistance solver shows good accuracy and fast computational speed. Numerical experiments demonstrate that the solver can be more than 10,000 times faster than the finite difference solver RAPHAEL while preserving good accuracy. And the proposed techniques accelerate the original BEM remarkably. Structures from real FPD designs have validated the efficiency of the proposed techniques.
