Abstract
Embodiments of a display device are described. The display device includes a backlight unit having a light source, a quantum dot film, and a radiation absorbing element. The quantum dot film is optically coupled to the light source and is configured to process light received from the light source. The radiation absorbing element is optically coupled to the quantum dot film and is configured to tune a spectral emission width of the processed light received from the quantum dot film to achieve over 90% color gamut coverage of a standard RGB color space.
