A quantum dot, which is 10,000 times smaller than the width of a human hair, can emit light at a very precise wavelength. The ability to control the spectral output of a quantum dot allows QDEF to create an ideal white backlight specifically designed for LCDs. Trillions of these quantum dots are packaged into a thin film that fits inside an LCD backlight unit. QDEF replaces a similar film already found inside LCD backlights, which means that adding QDEF to manufacturing processes requires no new equipment or process changes for the LCD manufacturer.
Precision alignment of RGB color wavelengths emitted by a QDEF to the color filter should have a significant impact on color purity on LCDs. Check out the photos of a QDEF enhanced iPad; the difference is quite noticeable.
