Publication number: 20230253532Abstract: A method includes depositing a layer comprising a photoinitiator and a curable material onto a surface and applying a nanoimprint mold on the layer of curable material to form a mesh comprising intersecting walls defining cavities. After applying the nanoimprint mold, the mesh is illuminated with light causing decarboxylation of the photoinitator to initiate curing of the curable material. After curing the curable material, the nanoimprint mold is removed and a wavelength converting material is deposited in the cavities to form an array of wavelength converting pixels.Type: ApplicationFiled: April 7, 2023Publication date: August 10, 2023Applicant: Lumileds LLCInventors: Danielle Russell Chamberlin, Erik ROELING, Daniel Bernardo ROITMAN, Kentaro SHIMIZU
