Abstract

A rear projection display apparatus for displaying an image reduces parallax error. The display apparatus includes a housing, a transparent screen support having top and bottom surfaces, a translucent display screen removably adhereable to the top surface of the screen support, and a projector to project the image onto the display screen. Optionally, a series of mirrors may be provided to sequentially reflect the image from the projector onto the display screen. In a preferred embodiment, the housing is pivotally mounted on a base, and houses the display screen, screen support, mirrors and projector.
