Screen refers to the white screen that is shown when a movie is shown.

Screen, a screen that projects enlarged images (pictures) when showing movies and slides. The original screen was made of white cloth. In order to improve the reflectivity of light and keep the reflected picture bright enough, the diffuse reflection screen used in general cinemas is made of cloth blank or plastic coated with barium sulfate or metal powder.

A screen for showing movies, originally made of white cloth. Later, cloth blanks coated with barium sulfate or metal powder or diffuse reflection screens made of plastic were often used. There are also reflective screens made of glass bead coatings and transmissive screens made of translucent materials. During the silent film period, the curtain was painted with dim white pigment, and the screen surface was flat, fixed with a permanent screen frame and erected on the projection platform.

After the sound film was born, rubber and plastic materials were used to make perforated screens because of the need of sound transmission. Let the speakers installed behind the scenes make sound through the screen. Cinemas generally use transparent screens. There is a small sound hole in the middle to facilitate sound penetration. Because there are main channel bass, white channel and left and right channels behind the screen. Cinema generally does not emphasize gain. Part 3D also needs to use a metal sound transmission screen.

The application scope includes: theme parks, museums, studios, film and television studios, national defense industry, golf simulators, architectural landscape attractions, churches, medical and educational facilities, conference room simulators, etc.

Characteristics of screen
