    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 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.

    Abstract: Embodiments of a device and a method of forming the same are described. The device includes a backlight unit and an image generating unit. The backlight unit includes an optical cavity having a top side, a bottom side, and side walls. The backlight unit further includes an array of light sources coupled to the optical cavity and a quantum dot film positioned within the optical cavity. The quantum dot film is configured to process light received from the array of light sources and the backlight unit is configured to transit the processed light to the image generating unit. The method includes providing an optical cavity having a top side, a bottom side, and side walls. The method further includes coupling an array of light sources to the optical cavity and supporting a quantum dot film within the optical cavity.
