Abstract
A display device in the form of a slim screen projector has a beam-splitter and a reflector co-planar and in contact with each other. Incident light from a light source strikes the beam-splitter and reflector and a portion thereof is directed towards a mirror. Light from the mirror then passes through a louvre-screen via the beam-splitter and strikes a viewing surface on which a viewable image is formed.
