Paper Abstract

Polymer dispersed liquid crystals have received much attention recently due to their potential applications in projection and direct view displays. In this paper, the effect of curing conditions, i.e., UV lamp power, exposure time and curing temperature, on the electro-optic properties of PDLC films are reported for both direct view and projection applications. The variation of electro-optic properties with variation of film thickness for different liquid crystal mixtures is also reported. The results presented indicate that an optimum curing temperature and lamp power exist at which an optimum contrast can be achieved for a given film thickness.
