Zusammenfassung:	A multi-projection screening system may include a projection apparatus projecting an image, a plurality of projection surfaces onto which the image is projected, a polymer dispersed liquid crystal (PDLC) panel disposed in some of the plurality of projection surfaces, and a server controlling the PDLC panel. A method of controlling a PDLC panel may include the steps of checking whether an image is projected onto the PDLC panel and controlling a color displayed on the PDLC panel. A multi-projection screening method may include the steps of projecting an image onto a projection surface disposed in the front of a theater, checking whether an image is projected onto a PDLC panel, and controlling a color displayed on the PDLC panel. In accordance with embodiments of the present invention, a totally uniform image can be provided, and a sense of difference between front and side projection images can be prevented from occurring.
