Abstract

1443151 Projection screens TIMOTHY BAK-KWAN LEUNG 17 Oct 1975 31354/72 Heading G2X [Also in Divisions H1 and H4] A three-dimensional effect is imported to cinepictures back-projected on to a display screen by affixing the smooth surface of a transparent sheet of glass or plastics material to the front surface of the screen, the other surface of the sheet being formed with a plurality of parallel semi-cylindrical rectilinear lenses, the convex surfaces of which face outwards, contact one another tangentially throughout their length, and have not been subjected to non-reflecting treatment or provided with a non-reflecting layer. The semi-cylindrical lenses may extend vertically, horizontally or diagonally off the screen.
