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.

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. The display device includes a first sub-pixel with a first quantum dot (QD) film and a first filter element. The QD film receives both UV light and blue light and converts a portion of the received light to emit a secondary light different from the UV and blue light.

The second sub-pixel has a second filter element that allows blue light to pass through the second filter element, and the second filter element blocks the UV light from passing through the second filter element.
