A movie, television, or computer screen on which two or more separate images are displayed
In film and video production, split screen is the visible division of the screen, traditionally in half, but also in several simultaneous images, rupturing the illusion that the screen's frame is a seamless view of reality, similar to that of the human eye.
Split screen is a display technique in computer graphics that consists of dividing graphics and/or text into non-movable adjacent parts, typically two or four rectangular areas.
An optical or special effects shot in which two separate images are combined on each frame.
