2A03 IPS TFT-LCDの特性解析 : 非対称界面アンカリングとしきい値特性

抄録

The threshold behavior of the in-plane switching (IPS) mode LC cells with different (asymmetric) anchoring strength at two LC/substrate interfaces was investigated by linear stability analysis. Similarity in stability characteristics between the IPS mode and the surface stabilized ferroelectric mode was clarified. The analysis showed that, with parallel rubbing of the two substrate surfaces, only the (symmetric) switching initialized from the center of the liquid-crystal layer will occur even with the asymmetric surface condition.
