摘要

The screen has independent projection surfaces (1-4), where each surface includes a frame on which translucent and foldable foils (19) are stretched. Each frame includes four strips and a circular edge (14), which is provided at a front side of the frame, and the foils are guided around the circular edge. Inner and outer surfaces of the frame are connected by the circular edge and form an angle within the range of 5-50 degrees.
