Abstract:
A method of fabricating a multi-color display includes forming a host matrix over a display having an array of light emitting diodes. The host matrix is sensitive to ultraviolet light. A first plurality of light emitting diodes in a first plurality of wells are activated to illuminate a portion of the host matrix to cause the portion of the host matrix to develop internal porous structures. A first photo-curable fluid including a first color conversion agent is dispensed. The first plurality of light emitting diodes in the first plurality of wells are activated to illuminate and cure the first photo-curable fluid to form a first color conversion layer over each of the first plurality of light emitting diodes, and an uncured remainder of the first photo-curable fluid is removed.
