Abstract: A method of printing structures on a reconstructed wafer includes positioning a plurality of semiconductor dies on a support substrate, anchoring the plurality of semiconductor dies to the support substrate by printing a plurality of anchors that extend across edges of the semiconductor dies onto the support substrate and thus form a reconstructed wafer, and printing one or more device structures on the pluralities of semiconductor dies while anchored on the support substrate. The printing operations include ejecting droplets of a liquid precursor material and curing the liquid precursor material.

Abstract: A light-emitting device includes a plurality of light-emitting diodes, a first cured composition over a first subset of the light-emitting diodes, and a second cured composition over a second subset of light-emitting diodes. The first cured composition includes a first photopolymer and a blue photoluminescent material that is an organic, organometallic, or polymeric material, embedded in the first photopolymer. The second cured composition includes a second photopolymer and a nanomaterial embedded in the second photopolymer. The nanomaterial is selected to emit red or green light in response.

Abstract: A method of fabricating a multi-color display includes dispensing a photo-curable fluid over a display having an array of LEDs disposed below a cover layer. The cover has an outer surface with a plurality of recesses, and the photo-curable fluid fills the recesses. The photo-curable fluid includes a color conversion agent. A plurality of LEDs in the array are activated to illuminate and cure the photo-curable fluid to form a color conversion layer in the recesses over the activated LEDs. This layer will convert light from these LEDs to light of a first color. An uncured remainder of the photo-curable fluid is removed. Then the process is repeated with a different photo-curable fluid having a different color conversion agent and a different plurality of LEDs. This forms a second color conversion layer in different plurality of recesses to convert light from these LEDs to light of a second color.
