Abstract: This article provides an overview of the basic structure, principle and preparation methods of polymer dispersed liquid crystal (PDLC) devices. The current development status and trend of PDLC devices are highlighted, including color devices based on dichroic dyes and flexible devices based on flexible transparent electrodes. The applications of PDLC in smart windows, privacy protection and sensors are summarized. Finally,the challenges of color and flexibility of PDLC devices are described and research direction are prospected.
