Abstract:
A method of fabricating a multi-color display includes dispensing a photo-curable fluid that includes a color conversion agent over a display having a backplane and an array of light emitting diodes electrically integrated with backplane circuitry of the backplane, activating a plurality of light emitting diodes in the array of light emitting diodes to illuminate and cure the first photo-curable fluid to form a color conversion layer over each of the first plurality of light emitting diodes to convert light from the plurality of light emitting diodes to light of a first color, and removing an uncured remainder of the first photo-curable fluid. This process is repeated with a fluid having different color conversion components for another color.
