What is "split screen"

n. 1 (context uncountable English) A display technique that consists into subdiving graphics that appear on a screen into nonmovable adjacent areas. 2 (context countable English) An instance of using the technique on the graphics of a screen.

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. There may or may not be an explicit borderline. Until the arrival of digital technology in the early 1990s, a split screen was accomplished by using an optical printer to combine two or more actions filmed separately by copying them onto the same negative, called the composite.

In filmmaking split screen is also a technique that allows one actor to appear twice in a scene. The simplest technique is to lock down the camera and shoot the scene twice, with one "version" of the actor appearing on the left side, and the other on the right side. The seam between the two splits is intended to be invisible, making the duplication seem realistic.

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. This is done in order to allow the simultaneous presentation of (usually) related graphical and textual information on a computer display. Split screen differs from windowing systems in that the latter allows overlapping and freely movable parts of the screen (the " windows") to present related as well as unrelated application data to the user, while the former conforms more strictly to the description given in the paragraph above.

The split screen technique can also be used to run two instances of an application, possibly with another user interacting with the other instance.

Split screen can refer to:

• Split screen (video production), the visible division of the screen
• Split screen (computer graphics), a display technique that consists of dividing graphics and/or text into non-movable adjacent parts
