Abstract: A rear projection unit has a screen mounted in a frame which supports a projector at a desired position in relation to the screen. The projector can thereby be positioned in various ways and the frame reduced and enlarged according to the requirements of the projection unit. The projection unit has a tapering shape and light absorbing material so that internal reflections are minimized and light absorption is maximized to enhance clarity of the screen. The frame itself is configurable with the arms being pivotable and extendable. A light absorbing material is stretched over the frame and a fan included to cool a projector within the unit and draw air into the unit through the material thereby serving the dual purpose of cooling and filtering air. A new material for absorbing light is also provided.
