Simultaneous determination of the pretilt angle and the cell thickness of a liquid crystal cell.

This paper presents a simple method for determining the pretilt angle and cell thickness simultaneously, which are critical factors in liquid crystal displays. Their determination was achieved from the incident angles, where the transmittance was the same for each cell rotation with crossed polarizers and parallel polarizers, based on the crystal rotation method. Unlike the conventional crystal rotation method, which has a limited measurement range, the proposed method could cover all ranges of pretilt angles. [ABSTRACT FROM AUTHOR]
