Optical Characterization of the Twisted Nematic Liquid Crystal Display

  • Carolina Rickenstorff (a1) and A. S. Ostrovsky (a1)

Abstract

A simple optical characterization technique is developed for to find the amplitude and phase modulation modes for the twisted nematic liquid crystal display (TN-LCD). The developed technique is based on intensity and pixel shift measurements of the interference pattern obtained from the TN-LCD sandwiched between two polarizers in a modified Young's experiment. Particularly, specimen LC2002 Holoeye is characterized and its amplitude and phase modulation curves as a function of image's gray level, bright B and contrast C are presented.
