Abstract
A number of light-emitting fibers in side-by-side array comprise a display. Each fiber includes a number of light-emitting elements disposed along the length of one surface of an optical fiber, such as an electro-luminescent material, e.g., an OLED material, disposed between hole injecting and electron injecting electrodes. Contacts on the top ones of the electrodes are connected by a conductor disposed transverse to the longitudinal direction of the fiber. The conductors are preferably deposited on the optical fibers by mask deposition, preferably utilizing masks adapted for contemporaneously depositing a metal conductor across a plurality of fibers. Electronic circuits having patterned conductors corresponding to the transverse conductors may be connected thereto by solder, conductive adhesive and the like.
