GLAZING COMPRISING A VARIABLE LIGHT DIFFUSION SYSTEM AND A PAIR OF ABSORBERS

摘要

The invention concerns a glazing comprising a substrate coated with a variable light diffusion system switching between a transparent state and a translucent state comprising a diffusing layer able to diffuse incident light at diffusion angles greater than the critical angle of total internal reflection at the interface between the substrate and the air and at least one pair of visible light absorbers separated from each other at least by the diffusing layer. The invention also concerns the use of said glazing as a projection or rear projection screen.
