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