Claim 21:
22. The method of claim 1, further comprising:
ejecting a second photocurable composition onto the array of micro-LEDs, wherein the second photocurable composition includes second quantum dots, second quantum dot precursor materials that comprise metal atoms or metal ions corresponding to metal components present in the quantum dots, a chelating agent configured to chelate the quantum dot precursor materials, one or more monomers, and a photoinitiator;
activating a second plurality of micro-LEDs from the array of micro-LEDs to illuminate the photocurable composition over the second plurality of micro-LEDs with light in the second wavelength band that causes the photoinitiator to initiate polymerization of the one or more monomers and causes the quantum dots to emit light in a different third wavelength band in the visible light range; and
removing an uncured portion of the second photocurable composition from the array of micro-LEDs.
