Quantum Dot (QD) technology offers the promise of efficient and relatively inexpensive liquid crystal displays (LCDs) with a large color gamut. Quantum dot displays now offer a variety of high color performance devices for applications ranging from 3” diagonal hand held smart phones to +85” diagonal TVs. Market research indicates that people clearly prefer these high color displays. Based on the ability to tune the emission wavelength and the narrow emission spectra, QDs are employed for use in LCD’s to improve the color gamut. The QDs produce a white backlight with very narrow and well defined primary colors. The primary colors can then pass through the color filters and transmit saturated primaries generating large color gamut displays. In order to make a commercial LCD application possible, a delivery format that maintains an air free environment and is easy to handle is required. This review will explore the application and material properties required to bring this technology to commercial success.
