摘要：
The polymer dispersed liquid crystal (PDLC) having continuous liquid crystal domains in a three dimensional spongy-like polymer network shows a light transmission-light scattering upon electric field ON and OFF, respectively. The PDLC film can be used as a light valve for an active matrix display. The driving voltage of the PDLC was below 6 volt, low enough to be driven by thin film transistor (TFT). The electro-optical properties of the PDLC film strongly depended on the temperature of panel and the physical properties of the polymer matrix. A real moving picture-projector was developed by using the 3.1' amorphous silicon TFT-PDLC light valves. The brightness of the projector was about two times higher than that of TN-TFT projector.
