Nanosys VP of R&D Dr. Jian Chen to speak at TFUG's Display and Lighting Conference in San Jose.

Abstract: Quantum dots are a new generation phosphor material that offers narrow emission line-width, high efficiency, wavelength tunability, and long lifetime.  By embedding green and red quantum dots in a flexible optical film -- quantum dot film – we achieved not only superior color saturation in LCDs that exceed OLED displays but also higher power efficiency than white LEDs for LCD backlights. Integration of quantum dots into LCDs can be readily achieved by making two changes in the manufacturing process: (1) replacing the white LEDs with blue LEDs; and (2) replacing the bottom diffuser with the quantum dot film in the backlight.  By utilizing the existing LCD color filters on the market today, 100% NTSC color gamut can be obtained using quantum dot films without sacrificing power efficiency.  The first commercial product using quantum dot films was introduced in 2013 in a tablet device.  More display products using quantum dot films will be launched in 2014 and 2015 that will greatly expand the color gamut of LCDs to 100% NTSC to enable Adobe-RGB and DCI-P3 color standards.
