Signboard for displaying optical images

摘要: The present invention constitutes a display system (10) for alpha-numeric and graphic images. provides signboard on which varying images of comparably large dimensions can be made to appear. comprises an input matrix (12), (14), number optical conductors (16) such as fibers interconnect corresponding parts the matrixes. Optical focused front face (15) appear in expanded form (24) output matrix. may constructed from small units (60) comprising bundle (62), block (22), group (66). These easily manufactured by process involving limited steps.
