Flexible PDLC film for gray scale with fast dynamic response made by controlled polymer orientation

Polymer network, which is used as a matrix for dipersing liquid crystal droplets, may be oriented in one direction by applying an oblique external electric field during photopolymerization induced phase separation. Liquid crystal molecules are aligned in the same direction as oriented polymer network wall. In this way, a PDLC film with fast dynamic response and gray scale for display application may be obtained. The results of studies of this problem are presented.
