Abstract: A light emitting device includes a first optical cavity bounded by cavity walls, a first light emitting diode located in the first optical cavity and configured to emit blue or ultraviolet radiation first incident photons, a first color conversion material located over the first light emitting diode and configured to absorb the first incident photons emitted by the light emitting diode and to generate first converted photons having a longer peak wavelength than a peak wavelength of the first incident photons, and a first color selector located over the first color conversion material and configured to absorb or reflect the first incident photons and to transmit the first converted photons.

Abstract: Embodiments of a display device are described. The display device includes a liquid crystal display (LCD) module and a backlight unit designed to emit a primary light in a first wavelength region of an electromagnetic (EM) spectrum. The LCD module includes an array of pixels having at least one pixel with a sub-pixel that includes a layer of luminescent nanostructures and a layer of fluorescent material. The layer of luminescent nanostructures absorbs the primary light and emits a second light in a second wavelength region of the EM spectrum different from the first wavelength region. The layer of fluorescent material absorbs the primary light that has passed through the layer of luminescent nanostructures, and emits a third light in the second wavelength region of the EM spectrum.

Abstract: 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 nanostructure-based color conversion (NS-based CC) layer and a light extraction layer. The NS-based CC layer 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 first portion of a secondary light having a second peak wavelength. The second peak wavelength is different from the first peak wavelength. The light extraction layer is optically coupled to the NS-based CC layer and is configured to prevent total internal reflection of a second portion of the secondary light. The light extraction layer has patterned features with one or more dimension in nanometer scale.
