Abstract

A display as for images and/or information comprises a plurality of linearly addressed 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 which is linearly addressed by signals provided by a drive circuit at one end thereof. Linear addressing signals are either optical signals or electrical signals, and may be frequency modulated, digitally encoded or analog encoded. A detector associated with each pixel detects the linear addressing signal and decodes same to activate and deactivate organic or inorganic light-emitting material elements. Thus, the light-emitting elements emit light to display a pixel or sub-pixel of the image and/or information. The light-emitting fiber may include a transparent fiber as substrate for propagating the optical signals therethrough and may include electrical conductors disposed along its length for propagating the electrical signals.
