Abstract

A pre-polymer matrix formulation for a polymer dispersed liquid crystal (PDLC) display includes, in one aspect, a monofunctional monomer, a trifunctional oligomer, and a trifunctional monomer. A product, in another aspect, includes a PDLC display formulation comprising a polymer matrix having a plurality of liquid crystal (LC) domains dispersed therein, wherein the polymer matrix comprises a polymerized product of a monofunctional monomer, a trifunctional oligomer, and a trifunctional monomer, and a pair of electrodes having the PDLC display formulation positioned therebetween. The PDLC display formulation is characterized as having a substantially constant optical transparency during application of a low power direct current (DC) electromagnetic field between the electrodes for a predefined duration of time.
