Drop-down screen and motorized wall. Easy-to-install as you just have to fix the structure that holds the screen funky inside. It is a very comfortable kind of screen for meeting rooms, schools and similar, as they allow the screen to collect within seconds, leaving the wall for other uses (such as a blackboard) or simply decorative issues. Model that is connected to mains and the folding and unfolding of the screen is done motorized. Models with the metal grid of black and white. Models made of PVC fabric and fiberglass for better projection quality and in 16:9 format.
