The device used to project movies is called a projector. Projectors are designed to take images from a source, such as a film reel, digital media, or a computer, and display them on a larger screen for an audience. Modern projectors utilize various technologies, including digital light processing (DLP) and liquid crystal display (LCD), to deliver high-quality visuals and sound. Historically, film projectors were common in theaters, while digital projectors have become prevalent in both commercial and home entertainment settings. Projectors have evolved significantly, making it easier for people to enjoy cinematic experiences in diverse environments, from cinemas to classrooms.
