A movie theatre screen is much more than meets the eye. Behind the screen, there is a complex system of components that come together to produce the picture and sound that we see and hear. Generally, a movie theatre screen consists of a projection booth, projection lens, projector, sound system, and a movie screen. In the projection booth, the film is loaded onto the projector and the image is projected onto the screen. The projection lens is used to focus the light and adjust the size of the image. The sound system is responsible for amplifying the sound and ensuring that it is heard clearly. Keywords: movie theatre screen, projection booth, projector, lens, sound system.
