Speaker: Jurgen Daniel, Palo Alto Research Center (PARC)
Title: Printed Electronics – Prospects and Challenges for Displays and Sensing Devices 

Abstract: Printed electronics is predicted to see substantial market growth in the near future. Although printing techniques have been routinely used for electronics applications in the past, the recent activities in printed electronics address a much wider materials set with the intent to achieve fully printed functional electronic devices. In the pursuit of this goal, the definition of ‘printing’ becomes often rather broad. This talk will give an overview of printed electronics and address prospects and challenges. The emphasis will be on inkjet technology which has the advantage of digital data printing and non-contact materials deposition. PARC’s activity in printed electronics includes flexible backplanes for electrophoretic displays and disposable sensor tapes to record events that can trigger traumatic brain injury. 

Speaker Background: Jurgen H. Daniel is Senior Scientist at the Palo Alto Research Center where his research includes printed electronics, display technologies, micro-electro-mechanical systems, and photovoltaics. Previously, he has worked at Oxford Instruments and at FEI Europe and in 1998 he was visiting scientist at the Matsushita Research Institute, Tokyo. He holds a Dipl. Phys. degree from the University of Erlangen-Nuremberg, Germany, and a Ph.D. in electrical engineering from the University of Cambridge, UK.

Speaker: Geoff Walker, Product Marketing Manager, NextWindow 
Title: LCD In-Cell Touch

Abstract: As the touch market has grown, the LCD manufacturers have become increasingly interested in participating in the market through integration of touch capability into LCDs. This technology, known as "LCD In-Cell", is a bit more complex than it seems at first glance. The LCD manufacturers are actually developing three different technologies (optical, contact-closure, and capacitive) and three different forms of integration (in-cell, on-cell, and out-cell). This seminar explores the characteristics, advantages, disadvantages and implications of all of these possibilities. Since all three of these technologies support multi-touch, the seminar begins with a definition & exploration of multi-touch as a foundation, as well as a very brief review of the touch market. 

Speaker Background: Geoff Walker is the Product Marketing Manager at NextWindow, the leading supplier of optical touchscreens used in Windows-7 touch monitors and all-in-one touch computers.

Title: Flexible Displays

Abstract: In this talk I will describe a short history of flexible electronic displays, some of the technical approaches towards achieving flexibility using both silicon-based and organic-based materials, with particular focus on manufacturing issues associated with flexible electronic displays. Despite the fact that plastic-based electronic displays were demonstrated around 30 years ago, there are still few commercial examples of flexible electronic displays. Therefore, I will also discuss some of the issues that have slowed adoption of flexible displays in the marketplace, and some technical and market challenges to enable these technologies to flourish.

Speaker: Dr. James Larimer, President of ImageMetrics, LLC 
Title: Image Artifacts in the Digital Era

Abstract: Over the past 40 years digital imaging technology has replaced analog technology for capturing, storing, transporting and reconstructing imagery. There has been a revolution and resulting technology paradigm shift in the imaging business. Today digital signal processing enables the creation of image content and has revolutionized the way artists use post-production technologies to alter the look of natural imagery or combine it with CGI. Liquid crystal light valves, micro-cavity light emitting plasmas, LEDs, OLEDs, and MEMS devices coupled with CCDs and CMOS sensors have invaded the imaging marketplace. One hundred years of experience with film and CRT based television produced an essential understanding of the unique distortion and artifacts produced by these technologies; these lessons must now be relearned as new technologies replace old ones. This lecture will outline the basic concepts to understand the interplay between the human visual system and the manner in which images today are processed by these new technologies. Image artifacts such as flicker, judder, jaggies, tone-scale distortion, color breakup, tone-scale banding, image smear, blurring, scaling and codex artifacts can be understood based upon the visual ergonomics or perceptual salience of artifactual signals produced by digital imaging technologies. Digital technologies have created a new array of image artifacts that compromise image quality and our ability to control it. Artifacts can be understood and managed if we understand how the eye codes and processes the image on the screen. Why these artifacts are particularly salient to the human visual system and how to control them is the subject of this talk.

Speaker Background: Dr. Larimer started his career as a university Professor and eventually Department Chairman, he directed the Sensory Physiology and Perception Program at the National Science Foundation before joining NASA as a Senior Scientist at the Ames Research Center. A 20-year career at NASA transformed his interests from human vision to the interaction of human vision with electronic imaging media.. He has held every office in the Bay Area Chapter of the Society for Information Display, and served as SID VP for the Americas and is an Associate Editor of JSID. He is now a consulting engineer in imaging technology.

Title: Display Interfacing – Managing the transitions and looking to the future

Abstract: The move to high speed serial display interfaces in handhelds is well underway, especially at HVGA formats and higher, yet a careful analysis that balances power, volume (size) and EMI with costs and your supply chain is always necessary. We’ll look at the capabilities of the new MIPI Alliance Display Serial Interface and VESA’s MDDI and show block diagrams of simple and more complex systems these interfaces allow. Perhaps the most active current debate is the optimal location of frame buffers that trade off cost and power consumption. Looking to the near future, display-as-subsystem concepts (touch and more complex backlight control for instance) highlight the need for a more universal or abstracted interface. Distributed mobile architectures that MIPI UniPro and concepts like Network on Terminal (NoTA) allow would provide a path to the next generation. I would like to reserve an extended time for discussion.

Speaker Background: James E (Jim) Schuessler currently works in system architecture and strategic marketing with National Semiconductor’s Personal Mobile Device segment. He chair’s the Mobile Industry Processor Interface (MIPI) Alliance Technical Steering Group and is past chair of the working group that created MIPI SLIMbus™.
