Abstract
A method of manufacturing a polymer dispersed liquid crystal, PDLC, film, the method comprising: forming a region of liquid polymer (206) on a substrate (212); depositing one or more liquid crystal, LC, formulations (214) into the liquid polymer; and thereafter curing (234) the liquid polymer (206) to thereby induce phase separation between the polymer (206) and the liquid crystal formulations (214), resulting in PDLC pixels (236) which are phase separated from the surrounding, cured polymer—thereby producing a PDLC film.
