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.
