Abstract (en)
[origin: EP0911791A2] This consists of a sheet (1) provided with the graphic images to be displayed, complemented with a transparent sheet (2) the surface of which facing (3) the actual sheet (1) is provided with a succession of axially juxtaposed semi-cylindrical relieves (4), whereas the opposite face is totally plane. The display sheet consists of strips with the same breadth as the optical semi-cylinders with which the transparent sheet is provided. The optical effect caused by the various semi-cylindrical surfaces and depending upon the viewing angle to the plane of paper, allows one of the graphic images arranged on the display sheet to be observed and not so the remainder. <IMAGE>
