Definition: Rear-Projection Television refers to a television in which the image is projected and reflected onto the screen from behind the screen, unlike traditional video and film projection in which the projector itself is placed in front of the screen, such as in a movie theater.

There are five basic elements in the construction of a rear-projection television.

First, there is the type of projector technology used to produce a video image.

Second, the type of lens assembly used to magnify the projected image.

Third, the necessity to employ a mirror to reflect the projected image.

Fourth, the screen upon which the reflected image is presented.

Fifth, the sealed box that contains all of the previous elements.
