  • Publication number: 20180122613
    Abstract: Systems and methods are described that relate to quantum dot (QD) structures for lighting applications. In particular, quantum dots and quantum dot containing inks (comprising mixtures of different wavelength quantum dots) are synthesized for desired optical properties and integrated with an LED source to create a trichromatic white light source. The LED source may be integrated with the quantum dots in a variety of ways, including through the use of a small capillary filled with quantum dot containing ink or a quantum dot containing film placed appropriately within the optical system. These systems may result in improved displays characterized by higher color gamuts, lower power consumption, and reduced cost.
