Patent number: 11973169Abstract: An optical isolation material may be applied to walls of a first cavity and a second cavity in a wafer mesh. A wavelength converting layer may be deposited into the first cavity to create a first segment and into the second cavity to create a second segment. The first segment may be attached to a first light emitting device to create a first pixel and the second segment to a second light emitting device to create a second pixel. The wafer mesh may be removed.Type: GrantFiled: September 4, 2020Date of Patent: April 30, 2024Assignee: Lumileds LLCInventors: Danielle Russell Chamberlin, Erik Maria Roeling, Sumit Gangwal, Niek Van Leth, Oleg Shchekin

Publication number: 20230313030Abstract: Photoactive organic ligands used to surface modify nanoparticles are described. The photo active organic ligands can be tailored to absorb radiation within a selected range of wavelengths. Upon absorption of radiation, the ligands react to alter the solubility of the ligand, and may be cleaved, and surface modification of the nanoparticles changes such that solubility of the nanoparticles changes. Coatings prepared with the surface modified nanoparticles can be radiation patterned and developed in accordance to methods described herein. Appropriate selection of a solvent as developer provides image formation facilitated by the difference in solubilities of the nanoparticles. Methods of radiation patterning the coatings are Luminescent nanoparticles surface modified with the photoactive organic ligands can be used to form down shifting light emission substrates suitable for use in electronic displays.Type: ApplicationFiled: April 3, 2023Publication date: October 5, 2023Inventors: Forrest S. Etheridge, Danielle Russell Chamberlin, Mehr Un Nisa Zaheer, Alexis V. Miranda, Marissa M. Tranquilli, Yu Kambe

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

Patent number: 11652134Abstract: A first component with a first sidewall and a second component with a second sidewall may be mounted onto an expandable film such that an original distance X is the distance between the first sidewall and the second sidewall. The expandable film may be expanded such that an expanded distance Y is the distance between the first sidewall and the second sidewall and expanded distance Y is greater than original distance X. A first sidewall material may be applied within at least a part of a space between the first sidewall and the second sidewall. The expandable film may be expanded such that a contracted distance Z is the distance between the first sidewall and the second sidewall, and contracted distance Z is less than expanded distance Y.Type: GrantFiled: June 3, 2022Date of Patent: May 16, 2023Assignee: Lumileds LLCInventors: Tze Yang Hin, Yu-Chen Shen, Luke Gordon, Danielle Russell Chamberlin, Daniel Bernardo Roitman

Publication number: 20220359799Abstract: A wavelength converting layer is partially diced to generate a first and second wavelength converting layer segment and to allow partial isolation between the first segment and the second segment such that the wavelength converting layer segments are connected by a connecting wavelength converting layer. The first and second wavelength converting layer segments are attached to a first and second light emitting device, respectively to create a first and second pixel. The connecting wavelength converting layer segment is removed to allow complete isolation between the first pixel and the second pixel. An optical isolation material is applied to exposed surfaces of the first and second pixel and a sacrificial portion of the wavelength converting layer segments and optical isolation material attached to the sacrificial portion is removed from a surface facing away from the first light emitting device, to expose a emitting surface of the first wavelength converting layer segment.Type: ApplicationFiled: July 26, 2022Publication date: November 10, 2022Applicant: Lumileds LLCInventors: Kentaro SHIMIZU, Hisashi MASUI, Yu-Chen SHEN, Danielle Russell CHAMBERLIN, Peter Josef SCHMIDT
