Abstract
Abstract There is disclosed a light transmitting display assembly provided with a source of electromagnetic radiation in the visible spectrum and comprised of a display board containing information and formed with channels into which ends of optical fibers of an optical fiber bundle are selectively positioned and after positioning the surface of the display board is coated with microbeads wherein the source of electromagnetic radiation is directed into the other ends of the optical fibers of the optical fiber bundle to provide a light transmitting display assembly capable of wide angle viewing.
