Abstract
The present disclosure generally relates to micro-ribbon structures used in display systems and methods of fabrication thereof. Individual fibers are made using an extrusion process whereby a core surrounded by an ink portion is extruded to create an individual fiber. The ink portion may include both an inner portion that is in contact with the core and an outer shell portion over the inner portion. The individual fibers are then bonded to adjacent fibers to create micro-ribbon structures. The micro-ribbon structures are of one color and spaced from adjacent micro-ribbon structures of a different color by a light blocking fiber. The micro-ribbon structures are each bonded to the light blocking fiber to create the color stripes used in the display system.
