发明名称 Rear-projection screen
摘要 The invention relates to a rear-projection screen whose optical and mechanical properties can be optimized substantially independently of one another. The back of the screen is provided with a two-dimensional structure of anamorphotic lenses in which a Fresnel lens may be integrated. The screen comprises a light-absorbing layer with transparent apertures in order to reduce the ambient light reflected by the screen.
