    Patent number: 3981573
    Abstract: A highly-compact audio-visual slide projection system which makes use of an array of co-planar rear-view screen sections forming a screen matrix for presenting images selectively derived from an adjacent array of individual slide projectors. Interposed between each screen section and its correspondingly-positioned projector on the same level therewith is a V-shaped reflector assembly whose inclined front leg faces the screen section and whose reversely-inclined rear leg faces the corresponding projector.
