Split-screen is a display technique that divides the screen into two or more sections, allowing different content to be shown simultaneously. This method is commonly used in video games, movies, and video conferencing applications, enabling users to view multiple perspectives or activities at once. In video games, split-screen allows multiple players to compete or cooperate on the same screen, enhancing the social experience. In movies, it can show parallel storylines or contrasting scenes. Applications like Zoom and Skype also utilize split-screen to facilitate group calls, making it easier for participants to see each other and shared content.
