Nanosys is a nanotechnology company located in Milpitas, California and founded in 2001. The company develops and manufactures quantum dot materials for display products. Products Quantum Dot Enhancement Film (QDEF) 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. 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. 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 (M-Series Quantum, P-Series Quantum & P-Series Quantum X) as well as TV manufacturers Hisense (ULED TV) and TCL (QLED TV) TV sets. In 2020, Nanosys announced a supply agreement with Shoei Chemical, a Japan-based producer of nanoparticles, under which the latter became the sole manufacturing partner of QD materials. QuantumRail Announced just after CES in January 2010 as part of a commercial agreement with Korean consumer electronics manufacturer and LG subsidiary LG Innotek, the quantum rail is a glass capillary optical component containing red and green quantum dots that is inserted between the LEDs and the lightguide panel (LGP) of an LED LCD in manufacturing to improve color gamut.
