Paper Abstract

Several different types of polymer dispersed liquid crystal (PDLC) systems have been developed in recent years. The transmission characteristics of each type depend on the materials used, the method of construction, and the addressing technique used to drive the system. Greater control over the transmittance response as a function of time is important for many display operations. The effect of using dual-frequency addressing and pulsed mode dual frequency addressing in controlling the transmittance response of one type of PDLC film has been investigated. The results suggest that the gray scale inconsistency as well as the hysteresis effect can be reduced by utilizing the frequency dependence of the dielectric anisotropy of the liquid crystal.
