Abstract

A projection and display apparatus comprising a light source (1) and a projecting means (2) for projecting light beams from the light source towards a screen. The apparatus comprises a first light-path (6) including an overhead printer sheet (16) to be displayed on the screen and a second light-path (7) including a slide projector film (23) to be displayed on the screen. The light beams are selectively directed towards either of the light-paths (6, 7). Liquid crystal shutters (15, 27) are interposed in each light-path and controlled by an electric voltage to selectively prevent or allow the passage of the light beams for selecting either of overhead printer sheet or slide projector film.
