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.
