Abstract

See full text

An LED is fabricated with a composite layer including quantum dots (QDs), wherein the QDs are provided in a silicone paste. A plurality of QD silicone paste reservoirs each contain a provided silicone paste with QDs of different wavelengths. Further, a silicone paste reservoir containing a clear silicone paste. A paste mixing chamber, in to which the QD paste reservoirs and the silicone paste reservoir supply their respective pastes, mixes together the pastes and form a mixed QD silicone paste. A silicone mixing and metering component receives the mixed QD silicone paste from the paste mixing chamber, and further receives A silicone and B silicone from a respective A silicone reservoir and a B silicone reservoir, measures, and mixes the mixed QD silicone paste with the A and B silicones to form a silicone polymer composite. A dispensing component receives to the silicone polymer composite from the mixing and metering component and dispenses the composite to a molding tool.
