Quantum dot tech for LCDs underway

Nanosys Inc. and the Optical Systems Division of 3M Company have collaborated to offer wide color gamut technology for consumer electronic displays. The companies will work together to commercialize Nanosys' Quantum Dot Enhancement Film (QDEF) technology, allowing LCDs to display 50 percent more color.

QDEF is a drop-in film that LCD manufacturers can integrate with existing production processes. It uses the light emitting properties of quantum dots to create an ideal backlight for LCDs.

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.
