Design of a zonal plate PDLC display

Abstract

In this work we present our studies of the optical properties of electrically switched Fresnel Zonal Plate using polymerdispersed liquid crystal (PDLC) materials. Our design is interpreted by using a theoretical approach to light scattering in PDLC films that relates optical transmittance and the order parameters, characterizing both the orientational structures inside bipolar droplets and orientational distribution of the droplets. The theory relies on the Rayleigh-Gans approximation and uses the Percus-Yevick approximation to take into account the effects due to droplet positional correlations.
