Title: Motion: Displays & Perception
Abstract: This talk will begin by covering the basics of the predominant display technology for television: Liquid Crystal Displays (LCDs), and referred to as LCTV for this application. After setting the foundation for several dimensions of image quality such as spatial, color, temporal, and dynamic range, as well as the corresponding human visual system capabilities along those dimensions, the talk will focus in on the main problem that has hindered the LCTV: motion. Since their introduction, LCDs were known for having a slower and asymmetrical temporal response compared to CRTs, which led to motion blur and flicker, respectively. For many years this hindered the use of LCD technology for television. Improving the temporal response time and the use of digital overdrive techniques led to a substantial reduction in motion blur. Still, some residual blur was visible in panned textures and scrolling text. Further analysis considering human visual system smooth-pursuit eye tracking combined with the hold-type temporal aperture used with LCTV has identified the remaining sources of blur. New techniques such as backlight flashing, black data insertion, and frame rate conversion reduce the motion blur to nearly that of CRT levels. However, the CRT is not necessarily the ultimate benchmark, as it suffers from its own artifacts, especially in the spatial dimension and with slow velocities. This talk will describe the key spatio-temporal properties of the visual system relevant to motion blur, and the various approaches used in LCTV technology toward improving overall moving picture sharpness.
Speaker Background: Scott Daly received a B.S. EE degree in 1980 from North Carolina State University, and then worked for a number of years with early high-resolution laser scanning systems at Photo Electronic Corporation in Florida. Shifting from hardware to wetware, he obtained an M.S. in Bioengineering from the University of Utah in 1984, with a thesis in neurophysiology on temporal information processing of cone photoreceptors. He then worked from until 1996 in the Imaging Science Division at Eastman Kodak in the fields of image compression (receiving a technical Emmy award), image fidelity models, and image watermarking. At Sharp Laboratories of America in Camas, Washington, he led a group on display algorithms. Eventually becoming a research fellow, he had opportunities to apply visual models towards digital video and displays, including starts in human interaction with wall-sized displays, audio perception and stereoscopic displays. These topics led him to recently join Dolby Laboratories in 2010 to focus on overall fundamental perceptual issues, and toward applications whose aim is to preserve artistic intent throughout the entire video path to reach the viewer. He received the Otto Schade award (for applied vision science) from SID in 2011 and is currently a member of IEEE, SPIE, and SID.

Title: The ICDM International Display Measurement Standard - SID's First Standard
Abstract: The ICDM (International Committee for Display Metrology) is the first standards development group within SID. This is the same metrology group who wrote the FPDM (Flat Panel Display Measurement standard) for VESA. Now that the group is part of SID, the ICDM is working on the final stages of the most comprehensive display measurement standard yet produced, the IDMS (International Display Measurement Standard). The standard defines metrology for a number of new areas, including 3D/stereo, motion artifacts measurements and assessment, temporal measurements never standardized before, dynamic contrast, front projector and projection-screen metrics, many grayscale and color-scale metrics, touch screens, expanded metrology for ambient contrast and other reflection measurements…and much more! The IDMS catalogs standardized methods to characterize displays of almost every type, with a range of measurements from common parameters often used to market displays, to state-of-the-art methods which capture important operating characteristics that have never had standardized quantification methods. In addition to the standardized measurements, the IDMS includes information on analysis methods applied to measurements, tutorials, overviews, metrology discussions, tables, references and a glossary, hundreds of metrology and reference items all within one cover. Joe’s presentation will consists of an overview of the ICDM and the IDMS standard, along with brief descriptions of some of the specialized areas included in the standard. If you have any interest in measuring and evaluating the quality of displays, don’t miss this meeting!

Speaker: Ted Sun, Ph.D., Founder, Sun Innovations
Title: Novel Emissive Projection Display on Fully Transparent and Black Screens
Abstract: A novel emissive projection display (EPD) system was recently developed by Sun Innovations. It is comprised of a fully transparent fluorescent screen and a dark light image projector. The screen can be applied to any glass window or windshield, without affecting visible light transmission. The dark light projector can be based on either a DLP (digital light processor) or a laser-scanner display engine. This display combines the best of both worlds from conventional projection and emissive display technologies. Like a projection display, the screen has no pixel structure and can be manufactured roll-to-roll; the display is scalable. Like plasma or CRT, the display is emissive with superior image quality and large viewing angles. It enables a fully transparent display on windows or windshields. The transparent emissive coating can also be applied to a pitch-black substrate for an innovative front-projection display on a black screen, with superior image contrast at low projection power. This fundamentally new display platform can enable multiple major commercial applications.
Speaker Background: Dr. Ted Sun graduated with a Bachelors Degree in Chemical Physics from the University of Science and Technology of China (USTC) in 1993, with thesis work on synthesis and characterization of iron oxide nano-particles. He did pioneering work with Prof. Peter Schultz at Lawrence Berkeley National Lab on combinatorial synthesis and screening of various functional materials. Ted received his Ph.D. in Chemistry from the University of California at Berkeley in 1998. He worked at GE Global Research as a project leader and senior staff scientist, and as the technology leader at two other high-tech businesses in Silicon Valley before founding Superimaging in 2004 and Sun Innovations in 2006. His research covers various areas of advanced materials and their applications, including lighting, displays, bio-medical imaging, solar cells, industrial coatings, anti-counterfeiting, etc. He is author of 15 peer-reviewed articles (three in Science) and over 50 patents in the United States alone (>30 have been issued). He is the Principle Investigator and recipient of numerous research grants and awards in the US and China. The transparent display technology that he invented just won the 2011 R&D 100 Award.

Speaker: Ken Werner, Principal, Nutmeg Consultants
Title: AMOLED Displays: Current Developments and Reckless Predictions
Abstract: The development of OLED displays has been a rocky road, with prediction after prediction running into delays and revisions. That’s typical for the development of new display technologies, but the huge promise of OLED coupled with the technology’s apparent simplicity made the delays particularly frustrating. Now, Samsung Mobile Display (SMD), the primary manufacturer of active-matrix OLEDs (AMOLEDs), can’t keep up with the demand, and both SMD and LG Display are planning to ramp up Gen 5.5 fabs in mid-2011. These are exciting times for AMOLED, and we can expect an array of new AMOLED-based products, but the melodrama is not over. As it turns out, although AMOLED technology appears simple, it isn’t. Great advances have been made on materials and device structure, resulting in vastly improved efficiency and lifetime, but the lifetime of blue emitters is still seriously deficient for many applications. Also, although the processes used for making both the OLED frontplanes and active-matrix backplanes are responsible for the technology’s current success, they are (at least in part) about to be pressed into use for the new, much larger fabs that will soon begin production – even though they have distinct limitations for even today’s generation. Process scalability is a critical issue if OLED displays are to be manufactured in larger sizes at a cost that allows them to be used in high-volume products. Therefore, it is not surprising that significant resources are being devoted to new processes that are suitable for fabs larger than Gen 5.5. In this overview, I will explore recent developments and current issues, and make some very specific (and perhaps slightly reckless) predictions about the immediate future.
