Abstract
A display as for images and/or information comprises a plurality of light-emitting fibers disposed in side-by-side arrangement to define a viewing surface. Each light-emitting fiber includes a plurality of light-emitting elements disposed along its length, each having two electrodes between which are applied electrical signals to cause the light-emitting element to emit light to display a pixel or sub-pixel of the image and/or information. The light-emitting fiber includes an electrical conductor disposed along its length to serve as a first electrode, a layer of light-emissive material disposed thereon, and a plurality of electrical contacts disposed on the light-emissive material to serve as the second electrodes of the light-emitting elements. Preferably, the conductors, light-emissive layer and plurality of electrical contacts are formed in a continuous process wherein a transparent fiber passes through a plurality of processing chambers for receiving the electrical conductor, the light-emissive layer and the plurality of electrical contacts thereon.
