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.

Abstract: Embodiments of the present disclosure relate to advanced polishing pads with tunable chemical, material and structural properties, and new methods of manufacturing the same. According to one or more embodiments of the disclosure, it has been discovered that a polishing pad with improved properties may be produced by an additive manufacturing process, such as a three-dimensional (3D) printing process. Embodiments of the present disclosure thus may provide an advanced polishing pad that has discrete features and geometries, formed from at least two different materials that include functional polymers, functional oligomers, reactive diluents, addition polymer precursor compounds, catalysts, and curing agents. For example, the advanced polishing pad may be formed from a plurality of polymeric layers, by the automated sequential deposition of at least one polymer precursor composition followed by at least one curing step, wherein each layer may represent at least one polymer composition, and/or regions of different compositions. Embodiments of the disclosure further provide a polishing pad with polymeric layers that may be interpenetrating polymer networks.

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.
