Transmission-type screen for video projector

摘要

The screen (10 on its rear side is provided with vertically running, inwardly arched lenses 11), and each lens is formed in the same manner, in that they refract the light beams coming from the Fresnel lens so that the light is spread in a horizontal plane between each two of the inwardly arched lenses (11) on the picture-producing screen (10) rear side.
