Comparison between a liquid-crystal display television screen using Nanosys Quantum Dot Enhancement Film (left) and a standard one (right).

Research into nanocrystals has recently been translated into the production of commercial devices. In May 2011, the company Nanosys announced a product called the Quantum Dot Enhancement Film6. This is a thin layer of quantum dots that convert the blue light of a GaN light-emitting diode into bright colours and can be used in liquid-crystal displays. Furthermore, the Amazon Kindle uses quantum dot technology for enhanced definition.
