A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
Many expect that quantum dot display technology can compete or even replace liquid crystal displays (LCDs) in near future, including the desktop and notebook computer spaces and televisions. These initial applications alone represent more than a $8-billion addressable market by 2023 for quantum dot-based components.
The first commercial application of quantum dots was the Sony XBR X900A series of flat panel televisions released in 2013. [108] In June 2006, QD Vision announced technical success in making a proof-of-concept quantum dot display and show a bright emission in the visible
Quantum dot displays utilize quantum dots to produce pure monochromatic light. Most of the work designing LEDs based on silicon quantum dots have focused on electroluminescence of the silicon quantum dots. [45] [46] By changing the size of the SiQDs, the LED emission can be tuned from deep red (680 nm) to orange/yellow (625 nm). [47]
The technology uses 2 liquid crystal layers instead of one, and may be used along with a mini-LED backlight and quantum dot sheets. [72] [73] LCDs with quantum dot enhancement film or quantum dot color filters were introduced from 2015 to 2018.
Nanosys Quantum Dot Enhancement Film, or QDEF, is an optical film component for LED driven LCDs. Each sheet of QDEF contains trillions of tiny Quantum Dot Phosphors.QDEF enables LED-backlit LCDs to be brighter and more colorful by providing a high quality, tri-color white light from a standard blue LED light source.

Different sized quantum dots emit different colour light due to quantum confinement. Quantum engineering is the development of technology that capitalizes on the laws of quantum mechanics. Quantum engineering uses quantum mechanics as a toolbox for the development of quantum technologies, such as quantum sensors or quantum computers .
