摘要

The projection wall has a screen (34) in each section (22) for a picture display. Each screen is enclosed in a thin-walled housing section (36) of truncated pyramidal shape, extending against the projection direction and open at the end away from it. The angle of the pyramid in the horizontal and vertical directions is smaller than that between the outermost beams on the longer and shorter sides of the picture to be projected. At the open end of the housing section it has a stabilising frame (38) with detachable connectors to the wall. USE/ADVANTAGE - For transparency and/or video projection with low-cost, quality display and suppression of dividing lines.
