Projection systems, which include projector screens, are the necessary equipment used for presentations. Projector screens are particularly useful when you deliver information to large gatherings or to groups seated in rooms more than 30 feet away from you. The projector screen makes your message visible from farther away.
Projection configurations may be either front or rear. In front-projection, the projector is placed in the presentation room, with the lens aimed directly at the projector screen standing at the front.
Making message visible from afar
The projector screen and associated equipment are positioned depending on their types and the particular lens employed.
