Abstract
The sign change of dielectricanisotropy at the characteristic crossover frequency of a nematic mixture is utilized in twisted nematicliquid crystal displays for turn‐off (decay) time reduction. This can be obtained by either (a) a two‐frequency addressing or (b) a high‐frequency erasing scheme where the high frequency is above the crossover frequency. Data are presented on Eastman Kodak 11900 nematic mixture.Keywords
