A projector screen is a surface that reflects light from a projector to create an image. It is an essential component of any projection system, as it provides a clear and bright surface for the image to be displayed on.
Projector screens come in a variety of sizes, shapes, and materials. The most common type of projector screen is the pull-down screen, which is made of a flexible material that can be rolled up when not in use. Pull-down screens are available in a variety of sizes, and they can be used indoors or outdoors.
