A 3D silver screen, also known as a silver lenticular screen, is a type of projection screen that was popular in the early years of the motion picture industry and passed into popular usage as a metonym for the cinema industry. The term silver screen comes from the actual silver (or similarly reflective aluminum) content embedded in the material that made up the screen’s highly reflective surface.
Acoustic Performance Screens are perforated to facilitate the acoustic performance of behind-screen speakers. For most cinema auditorium, standard perforated pattern is used. For close viewing (less than 5m/16ft), mini-perforated pattern is recommended.
Non-perforated screens are available for use when there are no speakers situated behind the screen.
The general environment where the screen is installed should be kept reasonably clean to avoid dirt and dust build-up. Screens can be periodically cleaned using a soft brush or cloth, doing this vertically with limited pressure. Screens can be cleaned using a damp cloth wetted with water and a mild detergent. Under no circumstances should screens be cleaned with abrasive materials or harsh chemicals such as acids, bleaches or solvents.
