The future of display technology
Quantum dot displays use an emissive layer of quantum dots to create the image the user sees. Because the quantum dot layer is excited electronically the need for a power-hungry backlight is eliminated, meaning quantum dot screens can be much thinner than contemporary plasma and LCD screens. Moreover, the stability of the inorganic quantum dots provides a considerably longer life expectancy than even the more advanced organic LED (OLED) screens.
QD screens are suitable for use in any situation where a plasma, LED or traditional CRT (cathode ray) display is found. From domestic televisions, to computer displays, to the screens of mobile phones. As well as this versatility, QD displays offer a number of striking benefits over older technologies: 
- Reduced power consumption
The absence of a backlight reduces the power consumption of QD displays significantly. - Improved definition and contrast.
Because LCD screens can never fully filter out their back light for darker areas of a picture, true blacks and the sharpest contrasts cannot be achieved, unlike QD displays which only emit light in those areas which are required to make the image. - Improved colour
Traditional CRT displays, though becoming less popular due to their bulk, have continued up to now to produce more vibrant images than plasma and LCD screens. A QD screen can render a greater range of colour variations than even the highest quality traditional CRT. - Manufacturing efficiency
During manufacture, quantum dots can be “printed” onto the substrate, in contrast to the vacuum deposition process currently used to make flat panel displays. Vacuum deposition wastes around 90 percent of the material used, while printing makes use of more than 95 percent of the material used.
