ABSTRACT:
A rear screen projection system integrated into the passenger cabin of an airplane. The system has a projector that directs a picture into the inner cavity of a housing. Also attached to the housing is a screen that has a first surface that faces the audience and a second opposite surface exposed to the inner cavity of the housing. Located between the projector and the housing is a mirror that reflects the picture from the projector onto the second surface of the screen. The screen is transparent to light so that the audience can view the picture on the first surface of the screen. The mirror is positioned such that the distance between the projector and the top and bottom edges of the screen are essentially equal. The mirror is also positioned such that even with an overhead projector, the incidence of light is normal to the screen and the picture is directed down toward the audience.
