What exactly is a quantum dot?

A significant improvement on existing LCD or LED methods, the technology works by shining blue light through nanocrystals of varying size from two to ten nanometres, which absorb light of one wavelength and emit light of another, very specific wavelength. Each dot emits a different colour depending on its size. A film of quantum dots of a size suitable to produce red and green light is added in front of the screen’s backlight. Generating light via the quantum dots narrows the wavelength of the red and green light produced, meaning less light is caught by the LCD filter. This means better colour rendition and brighter colours.
