(FR) ECRAN DE RETROPROJECTION
Abstract: front page image
(EN)The invention relates to an optical plate (12), in particular in a screen for a projection displaying device comprising on the first face thereof, optical elements (14) for erecting rays received from a light source in the form of a beam of rays in a first direction on the plane of a main axis (AA'). A second face (16) is embodied in such a way that it erects the beam in a second direction which differs from the first direction, preferably along the main axis (AA').
