Full screen display on face A; or
[0053] When the second control module 12 is used, each projection device C1 is controlled to project a corresponding video image in its corresponding main display area. The projected video images can be independent of each other, that is, displayed on the main display surface A Multiple video images instead of a whole coherent video image.
[0054] To sum up, in the preferred embodiment of the present invention, the first control unit 1 can control different projection devices C1 in the main projection device group C to project corresponding videos in the corresponding main display area on the main display surface A.
