In-situ curing of color conversion layer in recess

A method of fabricating a multi-color display, comprising:

• dispensing a first photo-curable fluid over a display having an array of light emitting diodes disposed below a cover layer that spans the array of light emitting diodes and has an outer surface with a plurality of recesses that extend partially but not entirely through the cover layer such that the first photo-curable fluid fills the recesses, wherein each light emitting diode has a corresponding recess, the light emitting diodes are electrically integrated with backplane circuitry of a backplane, and the first photo-curable fluid includes a first color conversion agent;
• activating a first plurality of light emitting diodes in the array of light emitting diodes to illuminate and cure the first photo-curable fluid to form a first color conversion layer in a first plurality of recesses over the first plurality of light emitting diodes to convert light from the first plurality of light emitting diodes to light of a first color;
• removing an uncured remainder of the first photo-curable fluid;
• thereafter dispensing a second photo-curable fluid over the display such that the second photo-curable fluid fills recesses of the plurality of recesses that are not filled by the first color conversion layer, the second photo-curable fluid including a second color conversion agent, wherein at least one of the first photo-curable fluid and the second photo-curable fluid includes a solvent;
• activating a second plurality of light emitting diodes in the array of light emitting diodes to illuminate and cure the second photo-curable fluid to form a second color conversion layer in a second plurality of recesses over the second plurality of light emitting diodes to convert light from the second plurality of light emitting diodes to light of a different second color;
• removing an uncured remainder of the second photo-curable fluid;
• and
• after curing of the said at least one of the first photo-curable fluid and second photo-curable fluid, evaporating the solvent.
