Polymer dispersed liquid crystals for high efficiency displays

摘要

Polymer dispersed liquid crystal (PDLC) films serve as the basis for a variety of high-efficiency electro-optical effects. In the most general sense, as PDLC materials consists of micron-sized domains of a liquid crystal, with the domain size determined by a continuous polymer matrix running through the film. Depending on the choice of liquid crystal and polymer, a variety of electro-optical effects have been demonstrated. Of these effects, scattering and dichroic-based displays are the most advanced, although development of cholesteric and smectic-based PDLC materials is of high interest.
