Patent number: 10475971Abstract: Quantum dots and methods of making quantum dots are described. A method begins with forming quantum dots having a core-shell structure with a plurality of ligands on the shell structure. The method includes exchanging the plurality of ligands with a plurality of second ligands. The plurality of second ligands have a weaker binding affinity to the shell structure than the plurality of first ligands. The plurality of second ligands are then exchanged with hydrolyzed alkoxysilane to form a monolayer of hydrolyzed alkoxysilane on a surface of the shell structure. The method includes forming a barrier layer around the shell structure by using the hydrolyzed alkoxysilane as a nucleation center.Type: GrantFiled: July 19, 2018Date of Patent: November 12, 2019Assignee: Nanosys, Inc.Inventors: Shihai Kan, Jay Yamanaga, Charles Hotz, Jason Hartlove, Veeral Hardev, Jian Chen, Christian Ippen, Wenzhuo Guo, Robert Wilson

Patent number: 10243114Abstract: Embodiments of a display device including barrier layer coated quantum dots and a method of making the barrier layer coated quantum dots are described. Each of the barrier layer coated quantum dots includes a core-shell structure and a hydrophobic barrier layer disposed on the core-shell structure. The hydrophobic barrier layer is configured to provide a distance between the core-shell structure of one of the quantum dots with the core-shell structures of other quantum dots that are in substantial contact with the one of the quantum dots. The method for making the barrier layer coated quantum dots includes forming reverse micro-micelles using surfactants and incorporating quantum dots into the reverse micro-micelles. The method further includes individually coating the incorporated quantum dots with a barrier layer and isolating the barrier layer coated quantum dots with the surfactants of the reverse micro-micelles disposed on the barrier layer.Type: GrantFiled: March 5, 2018Date of Patent: March 26, 2019Assignee: Nanosys, Inc.Inventors: Jason Hartlove, Veeral Hardev, Shihai Kan, Jian Chen, Jay Yamanaga, Christian Ippen, Wenzhuo Guo, Charles Hotz, Robert Wilson

Publication number: 20190064591Abstract: Embodiments of a display device are described. A display device includes a backlight unit having a light source and a liquid crystal display (LCD) module. The LCD module includes a phosphor film and a filter element. The phosphor film is configured to receive a primary light, from the light source, having a first peak wavelength and to convert a portion of the primary light to emit a secondary light having a second peak wavelength. The second peak wavelength is different from the first peak wavelength. The filter element is optically coupled to the phosphor film and is configured to allow the secondary light to pass through the filter element and to block an unconverted portion of the primary light from passing through the filter element.Type: ApplicationFiled: August 22, 2018Publication date: February 28, 2019Applicant: Nanosys, Inc.Inventors: Ernest Lee, Jason Hartlove, Shihai Kan, Jian Chen
