Title: Flexible flat color display

Abstract: A flexible electronic color display includes a light-emitting diode (LED) matrix formed from an interweaved weft of conductive strands and warp of light-emitting diode (LED) fiber of a conductive core coated with a p-doped semiconductor and then an n-doped semiconductor of light-emitting polymer. Each conductive strand physically and electrically couples to each LED fiber at one location to form an LED that may activated as a pixel. Alternating LED fibers of different hues may provide a color display, especially for a relatively fine weave or for displays viewed from a distance. Alternatively, conductive strands and LED fibers may be selected having sufficient transparency that layers of multiple LED matrices, each having a selected hue, may form a color flexible display. In addition, methods for fabricating the LED matrix and for detecting and eliminating flaws from the LED matrix allow for economical manufacture.
