<P>PROBLEM TO BE SOLVED: To reduce flicker, on stack/multi-projection using a plurality of projectors each having a liquid crystal double-speed display panel. <P>SOLUTION: When performing stack projection, the phases of the positive/negative frames of liquid crystal driving signals to the liquid crystal panels (12a, 12b) from the liquid crystal driving parts (44a, 44b) of the respective projectors (10a, 10b) via D/A convertors (48a, 48b) are reversed each other. When performing multi-projection, the phases of the positive/negative frames of the liquid crystal driving signals to the liquid crystal panels (12a, 12b) of the respective projectors (10a, 10b) which display adjacent images are made equal to each other. <P>COPYRIGHT: (C)2011,JPO&INPIT |
