摘要：

A new method of measuring the low tilt bias angles of liquid-crystal displays is proposed. It is based on the threshold characteristics of magnetocapacitance, which vary according to the relative direction of the magnetic field and the directors. The tilt bias angle is determined completely by geometrical configurations and without any fitting procedure. The method ensures accuracy up to 0.1°in the present example. Threshold field variations due to sample rotation in the magnetic field are calculated from the theoretical magnetocapacitive curves, and experimental results are in good agreement with them.
