Abstract

We investigated the electrooptical properties of CNT-doped LC cells. A tiny CNT dopant increases the threshold voltage and decreases the fall time of cells due to the increase in the elastic constant of LC-CNT dispersion. At a higher CNT concentration, the increase in the dielectric anisotropy of LC-CNT dispersion decreases the rise time and threshold voltage of the cell. We also found that the hysteresis reduction in CNT-doped LC cells is not completely attributed to the ion trapping by CNTs.
