Electro-optical Characteristics of Splay-aligned Twisted Nematic Liquid crystal Display

Abstract

Electro-optical characteristics of a splay-aligned (SA) twisted nematic (TN) liquid crystal display (LCD) are calculated and are compared with those of an uniform-aligned (UA) TN-LCD. The liquid crystal orientation of the SA TN-LCD for the voltage range around the threshold voltage is different from that of the UA TN-LCD and this results in different electro-optical characteristics for the SA TN-LCD especially at oblique incidences.
