Progress in Luminous Array Film (LAFi) with Plasma Tube Technology for Seamless Tiling Super-large-area Display.
Terukazu Kosako, Shinoda Plasma Co., Kobe, Japan. A newly developed flat sealing process provides a minimal seam when overlapping transparent tube edge connections. Using these techniques, it is possible to produce an expandable 1 meter x 2 meter standalone display module.

The Study of Picture Quality of OLED TV with WRGB OLED Structure
Jong-Kun Yoon, OLED Development Group, LG Display Co., Ltd., Gyeonggi-do, Korea. After introducing the world’s first WRGB-based large-screen OLED TV last year, LG presents the results of a recent picture quality study of OLED TVs. 

Testing 3D Stereo Displays: Techniques and Challenges
Adi Abileah, Planar Systems, Beaverton OR.  Each 3D technology has unique measurement challenges. Extinction ratio and variations between the eyes are among the parameters measured to determine image quality and stereo effect. 

Efficiency Improvement of Fluorescent Blue Devices by Molecular Orientation of Blue Dopants
Toshinari Ogiwara, Idemitsu Kosan Co., Ltd., Chiba, Japan.  In a study of the relationship between the molecular shape of fluorescent blue dopants (BDs) and molecular orientation, BDs with larger ovality showed a higher orientation factor and higher EQE over 10% in a fluorescent blue device. 

The Need for Speed in Touch Systems
Albert Ng, Microsoft Corporation, Redmond, WA. Touch-to-display latency, frame rate, and motion blur greatly impact the user experience of a touch system. Using a custom device, the authors achieve latencies down to ~1ms, with frame rates up to 1000Hz.

Ink-jet Printed 17-inch AMOLED Display with Amorphous IGZO TFT Backplane
Ze Liu, BOE Technology Group Co., Ltd., Beijing, China.  A 17-inch full-color active-matrix organic light-emitting diode (AMOLED) display has been developed, which uses amorphous indium-gallium-zinc oxide (IGZO) thin film transistors and ink-jet printing technology.

High Efficiency Waveguide Display System with Achromatic Volume Hologram and a Prism In-coupler
Zhengmin Wu, Beijing Institute of Technology, Beijing, China. A waveguide display system with high efficiency is proposed that uses an embedded in-coupling prism and an out-coupling reflective volume holographic element.

 
 Development of IGZO-TFT and Creation of New Devices Using IGZO-TFT
Yoshiharu Kataoka, Sharp Corporation, Mie, Japan.  A high-performance LCD using IGZO was produced for the first time in the world.

Advanced Glass Substrate for the Enhancement of OLED Lighting Out-coupling Efficiency
Nobuhiro Nakamura, Asahi Glass Co., LTD., Yokohama, Japan.  An out-coupling technology using a high refractive index glass scattering layer with white OLED shows an efficiency 2.1 times higher than that of reference materials. 
 

The Joys of Being Digital for Low-Power, Mobile, Multi-Media Devices
Richard S. Payne, Pixtronix Inc., Andover, MA.  A digital MEMS technology helps deliver low power consumption, exceptional image quality, and ease of manufacturing.
  

 Highly Efficient White OLEDs with Over 100 lm/W for General Lighting
Kazuyuki Yamae, Panasonic Corporation, Eco Solutions Company, Osaka, Japan.  High-performance all-phosphorescent white devices on a light-outcoupling substrate made from high-index materials showed an extremely high efficacy.
