REFLECTIVE PROJECTION SCREEN COMPRISING A VARIABLE LIGHT SCATTERING SYSTEM

摘要

The invention relates to a glazing used as projection screen operating in reflection, comprising a front face, onto which the image is projected, and a rear face. The glazing comprises a variable light scattering system comprising a functional film capable of switching between a transparent state and a scattering state and a coating comprising at least one mirror layer, said coating being separated from the front face at least by the functional film.;The invention also relates to the use of a glazing as projection screen, to a projection system and to a projection method using said glazing.
