3M chooses quantum dots for LCD color boost

June 5, 2012 — Nanosys Inc. will supply the Optical Systems Division of 3M Company with quantum-dot-based technologies to provide wide color gamut for consumer electronic displays, allowing liquid crystal displays (LCDs) to display 50% more color.

 3M and Nanosys will work together to commercialize Nanosys’ Quantum Dot Enhancement Film (QDEF) technology. QDEF is a drop-in film that LCD manufacturers can integrate with existing production processes. It utilizes the light-emitting properties of quantum dots to create an ideal backlight for LCDs. The QDEF product took a gold award in the Display Component of the Year category of Society for Information Display (SID)’s Display Industry Awards this week.

Current LCDs are limited to displaying 35% or less of the visible color spectrum. Wide color gamut displays will enable more immersive and truer-to-life displays.

Color performance “has been largely neglected for the last decade,” said Jason Hartlove, president and CEO of Nanosys, adding that the drop-in quantum dot technology offers competitive advantage to LCD manufacturer against new display technologies such as organic light-emitting diodes (OLEDs).

A quantum dot’s precise light-emission wavelength allows QDEF to create an ideal white backlight specifically for LCDs. The film packages trillions of quantum dots into a thin film inside an LCD backlight unit, without new equipment or process changes for the LCD manufacturer.
