摘要/描述

In this paper a two-dimensional (2-D) dynamicmodel, based on a tensor formulation and solved numericallyby combining finite elements and finite differences, is proposedand used for analyzing nematic liquid crystal (LC) test cells withinterdigital electrodes. We compare theoretical and experimentalresults concerning the switching behavior, response mechanism,and viewing angle characteristics of nematic LC pixel structureswhich use the in-plane-switching (IPS) mode. The good agreementobserved between theory and experiment in terms of electroopticalproperties validates our modeling and demonstrates itspotential for design optimization. We show that the proposed LCtest cells, using the in-plane-switching mode, ensure switching-ON and -OFF response times of 22 and 28 ms, respectively, andexcellent viewing angle characteristics.
