发明名称 Projector screen made from a composite glass
摘要 A projection screen (1) made of a laminated glass which has at least two glass plates (3, 4) bonded to each other by means of a layer of plastic (2) is described. In order to create advantageous construction conditions, it is proposed that the glass plate (3) facing the projection bears on its outer side (6) a translucent ceramic coating extending at least over the projection area and that the glass plate (4) facing away from the projection preferably has a surface roughness preventing reflections.
