Specialty application rear projection screen. The Holo Screen is a holographic rear projection screen for point-of-sale applications in retail stores, window displays, airports, banks and other high traffic areas. Available in sizes up to 108” x 300”, the Holoscreen features an advanced holographic technology that displays images rear projected from 18-35 degrees. The result is a remarkably bright and clear image – even in brightly lit environments. The transparent display allows viewers to look at and see through the screen.
