Abstract: A LED display fabrication tool includes a plurality of chambers including an initial chamber, a final chamber, and a plurality of intermediate chambers, and the plurality of chambers are arranged to form a transfer line from the initial chamber to the final chamber with each intermediate chamber coupled by a first sealable port to a prior chamber in the transfer line and by a second sealable port to a subsequent chamber in the transfer line. The plurality of chambers include first and second dispensing chambers to deliver first and second color conversion precursors onto a workpiece for fabrication of a light emitting diode (LED) displays, and first and second washing/drying chambers to remove uncured portions of the first and second color conversion precursors. First and second curing stations cure the precursors.

Abstract: A photocurable composition includes quantum dots, quantum dot precursor materials, a chelating agent, one or more monomers, and a photoinitiator. The quantum dots are selected to emit radiation in a first wavelength band in the visible light range in response to absorption of radiation in a second wavelength band in the UV or visible light range. The second wavelength band is different than the first wavelength band. The quantum dot precursor materials include metal atoms or metal ions corresponding to metal components present in the quantum dots. The chelating agent is configured to chelate the quantum dot precursor materials. The photoinitiator initiates polymerization of the one or more monomers in response to absorption of radiation in the second wavelength band.
