A display system comprising: a screen having a concave screen surface positioned so as to be visible to a user of the system; said screen comprising a plurality of screen elements supported adjacent one another so as to form said concave screen surface, each of the screen elements comprising a respective faceplate comprising optical fibers extending adjacent each other so as to transmit light therethrough between two opposing faceplate surfaces; one of said faceplate surfaces being a concave display image output surface; and the other of said faceplate surfaces being an image input surface; and a respective light engine having a respective field of pixels each transmitting light corresponding to imagery comprising serial images of said light engine; and the fibers of the associated faceplate receiving the light of the pixels of the light engine and together transmitting said light from the light engine coherently to the image output surface thereof so that the images of the light engine are displayed on the image output surface; said faceplates abutting each other along adjacent edges thereof with the image output surfaces of said faceplates together form ing a substantially smooth and continuous curved portion of the screen surface so that the imagery displayed on the screen surface through said faceplates from the associated light engines is continuous between said faceplates, characterized in that some of the screen elements are kite-shaped wherein the input surfaces of the faceplates of the kite-shaped screen elements are planar and kite-shaped, and the images from the light engines are kite-shaped and substantially the same size as the input surface of the associated faceplate, wherein the planar and kite-shaped input surfaces are angled relative to each other, wherein some of the screen elements are kite-shaped having two connected short sides and two connected long sides, and being configured so that the screen elements together form a polygonal portion of the concave screen surface, and wherein the kite-shaped faceplates each have four planar side walls (57,59) that are perpendicular to the planar image input surfaces; and wherein the planar side walls are fixedly secured to support structures that hold said faceplates in position such that the faceplates together provide said concave screen surface as a continuous and smooth spherical display surface. a screen having a concave screen surface positioned so as to be visible to a user of the system; said screen comprising a plurality of screen elements supported adjacent one another so as to form said concave screen surface, each of the screen elements comprising a respective faceplate comprising optical fibers extending adjacent each other so as to transmit light therethrough between two opposing faceplate surfaces; one of said faceplate surfaces being a concave display image output surface; and the other of said faceplate surfaces being an image input surface; and a respective light engine having a respective field of pixels each transmitting light corresponding to imagery comprising serial images of said light engine; and the fibers of the associated faceplate receiving the light of the pixels of the light engine and together transmitting said light from the light engine coherently to the image output surface thereof so that the images of the light engine are displayed on the image output surface; said faceplates abutting each other along adjacent edges thereof with the image output surfaces of said faceplates together form ing a substantially smooth and continuous curved portion of the screen surface so that the imagery displayed on the screen surface through said faceplates from the associated light engines is continuous between said faceplates, characterized in that some of the screen elements are kite-shaped wherein the input surfaces of the faceplates of the kite-shaped screen elements are planar and kite-shaped, and the images from the light engines are kite-shaped and substantially the same size as the input surface of the associated faceplate, wherein the planar and kite-shaped input surfaces are angled relative to each other, wherein some of the screen elements are kite-shaped having two connected short sides and two connected long sides, and being configured so that the screen elements together form a polygonal portion of the concave screen surface, and wherein the kite-shaped faceplates each have four planar side walls (57,59) that are perpendicular to the planar image input surfaces; and wherein the planar side walls are fixedly secured to support structures that hold said faceplates in position such that the faceplates together provide said concave screen surface as a continuous and smooth spherical display surface.
