Nanosys is a nanotechnology company located in Milpitas, California, founded in 2001. Nanosys designs products for displays based on quantum dots.
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 LCDs to be brighter and more colorful by providing a high quality, tri-color white light from a standard blue LED light source. Larger than a water molecule, but smaller than a virus, these tiny phosphors convert blue light from a standard Gallium Nitride (GaN) LED into different wavelengths based upon their size. Larger dots emit longer wavelengths (red), while smaller dots emit shorter wavelengths (green). Blending together a mix of dot colors allows Nanosys to precisely engineer a new spectrum of light to customer specifications.
The Quantum Dots are tuned to create better color by changing their size during fabrication to emit light at just the right wavelengths. Traditional light emitting materials such as crystal phosphors have a broad fixed spectrum. Quantum dots can convert light to nearly any color in the visible spectrum, giving display designers the ability to tune and match the spectrum more accurately to color filters while improving energy efficiency. Designed to replace the functionality of a diffuser sheet while actively converting color, QDEF can be added to an LCD's film stack with little change in overall thickness or manufacturing process (Fig 1).
QDEF was announced on May 17, 2011 at the Society for Information Display (SID) Display Week tradeshow. It has been adopted in products such as the Amazon Kindle Fire HDX 7 (2013) and the ASUS Zenbook NX-500 (2014).
At the Consumer Electronics Show 2015 it became known that Nanosys has licensed Samsung Electronics as well as 3M to manufacture QDEF products. QDEFs from 3M are used by top US TV brand Vizio (R-Series) as well as Chinese LED-backlit LCD TV manufacturers Hisense (ULED TV) and TCL (QLED TV) TV sets.
