Patent number: 11506929Abstract: 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 light source is configured to emit a primary light having a first peak wavelength. The LCD module includes a first sub-pixel having a phosphor film and a second sub-pixel having a non-phosphor film. The phosphor film is configured to receive a first portion of the primary light and to convert the first portion of the primary light to emit a secondary light having a second peak wavelength that is different from the first peak wavelength. The non-phosphor film is configured to receive a second portion of the primary light and to optically modify the second portion of the primary light to emit an optically modified primary light having a third peak wavelength that is different from the first and second peak wavelengths.Type: GrantFiled: August 14, 2019Date of Patent: November 22, 2022Assignee: Nanosys, Inc.Inventors: Ernest Chung-Wei Lee, Charles Hotz

Patent number: 11275205Abstract: A display device is provided having a quantum dot formed directly on a surface or substrate of a backlight unit, without requiring an intervening layer. An optically transmissive layer is formed thereon. The quantum dot film may be provided that includes a population of optical features to permit the omission of additional films, such as a separate optical film. A population of optical features may include a population of embedded microspheres to achieve optical effects, to improve the overall thickness uniformity of the quantum dot film, or both. Additionally or alternatively, the quantum dot film may be provided having optical features embossed thereon, such as reflective and/or refractive features, prisms, grooves, grooved prisms, lenticular lenses, micro-lenses, micro-spheres, any other lenses, pitches, or other suitable brightness enhancement and/or optical features. Thereby, a separate optical film may be omitted from the overall device structure.Type: GrantFiled: July 24, 2019Date of Patent: March 15, 2022Assignee: NANOSYS, Inc.Inventor: Ernest Chung-Wei Lee
