Abstract
A flat projection television comprising an imagine engine mounted adjacent a top of an enclosure and optically coupled to a collimator mirror, a flat mirror, a mirror assembly comprising a plurality of cylindrical mirrors, and a diffuser screen. The image engine includes a cylindrical lens which expands an outgoing image horizontally. The image engine projects the image downward from the top of the enclosure toward the bottom of the enclosure where the horizontally expanding image encounters the collimator mirror which collimates the expanding beam bringing the horizontal lines back into parallel with one another. The collimator mirror also reflects the collimated image towards the front of the enclosure where it encounters the flat mirror oriented to deflect the image upward into the mirror box location of the enclosure at an appropriate angle. As the image is projected from the flat mirror, it encounters the cylindrical mirrors of the mirror assembly which expand each horizontal line of the image to present a fully expanded and complete image on the diffuser screen.
