Is the movie a big screen or a big screen?

The film uses a screen. Screen is a white curtain used to show traditional projection movies, usually dull white paint, which does not emit light itself. Usually the size is larger, and the common size is between 15-30 meters, which can bring more shocking visual experience. The screen is the carrier of the film. Without it, watching movies would be impossible. The high-gain screen can resist the influence of ambient light on projection and present a more stable viewing effect. It should be noted that the movie screen is sometimes called a screen, but it refers to the display screen on a TV or computer monitor, which is relatively small in size, and the common size is between 20 and 50 inches, so the viewing experience is more private. Therefore, movies are the big screen, not the big screen.
