2:00 PM Introduction and Welcome

2:05 - 2:35 PM Jian Chen, Nanosys, Inc.
High efficiency LCDs using Quantum Dot Enhancement Film

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.

Bio: Dr. Jian Chen is Vice President of Research and Development at Nanosys, where he is leading the development of a new generation of lighting technology based on quantum dots. Since joining Nanosys in 2002, Dr. Chen has directed research efforts across a variety of applications. His leadership on quantum dot commercialization has led to key breakthroughs in performance and manufacturability.

Prior to joining Nanosys, Dr. Chen spent four years at Seagate Technology, developing spin-valve read-heads for magnetic hard-drives.

Dr. Chen has a bachelor's degree in Physics from Peking University, a Ph.D. in condensed matter physics from the Ohio State University, completed post doctorate research at the University of Florida and is the author of 26 patents.

2:35 - 3:05 PM Jacques Matteau, Indium Corporation
A novel method of managing joint stress, in a metallic bond made using reactive multilayer foils, at a user selected temperature (for applications of bonding LEDs to heat sinks)

Previously we have presented a joining method whereby materials of widely differing CTE were successfully bonded with no deformation at room temperature using reactive multilayer foils as the local heat source. This is unique in as far as creating a metallic bond with any other technique results in significant deformation upon cooling back to room temperature.

For many large area applications this deformation results in having to use mechanical methods to flatten these surfaces to their original shape, which is highly undesirable as such techniques are unpredictable and do cause yield loss when used. When reactive multilayer foils are used in the bonding process, no such deformation of materials occurs resulting in assemblies that can be effectively used as soon as they are bonded.

Critical to the use of parts at higher temperature is the need to minimize/manage joint stress in assemblies at a particular application temperature. This paper will demonstrate how this can be done effectively, with the use of a reactive multilayer foil in creating the bond.

3:05 - 3:30 PM Break

3:30 - 4:00 PM Bard Pedersen, Adesto Technologies
Reinventing Memory for Things (TM) - Application specific memory solutions for integrated, connected, and high-temperature applications

4:00 - 4:30 PM Lars Dugaiczyk, Luxim Corp.
High power radio-frequency plasma light sources for industrial applications
High frequency electrodeless discharge lamps are finding new applications in industrial applications such as UV curing, ellipsometry, and as broad spectrum light sources. Electrodeless lamps offer several advantages over conventional electroded mercury and metal halide lamps and LEDs including extended lifetimes with little degredation in output, and also produce a unique near-continuum blackbody-like spectrum suitable for specialized scientific and medical applications.

Bio: Lars Dugaiczyk is a process and product development engineer at Luxim Corp. He has worked in the lighting industry since 2006, developing products for commercial and military applications.

All presentations will be requested to be posted on the TFUG Proceedings webpages.
