2019 Program



   2019 Special Topics




SID's Sunday Short Courses offer a thorough introduction to topic fundamentals for students, scientists, and engineers looking to expand their technical breadth into a new area. The four-hour Short Courses differ from SID's 20-minute Symposium talks and 90-minute Seminars, which generally focus on the latest developments in specific technical areas, adding technical depth. By having these introductory courses at the start of Display Week, attendees can learn the fundamentals first, before absorbing advanced presentations on focused topics in the Seminars and Symposium.

S-1: Fundamentals of Quantum Dots and Their Application to Displays
The quantum dots (QDs) reviewed in this short course are chemically synthesized colloidal QDs. They are semiconducting nanocrystals, also known as artificial atoms. Their size is only a few nanometers, which is close to or smaller than their electron Bohr radius. A strong quantum confinement effect will occur, which is reflected by the fact that the emitted color of the QD is directly dependent on the size of the QD.
After years of research and development, state-of-the-art synthesized QDs are now known for their high quantum yield and narrow emission bandwidth, making them suitable for practical applications for displays, though there is still some development to be done for lighting applications. In this course, we will review the fundamentals of QDs, including their development history, the critical parameters to define QDs (size, composition, [core/shell or alloyed] structures, and shape, etc.), the cadmium (Cd) issue, and the physical properties of QDs (absorption, photoluminescence, quantum yield, bandwidth, blinking issues), etc. We will also introduce the development of applying QDs to displays, which includes photoluminescence (PL) and electroluminescence (EL).
• In PL, we will explain the application of QD as the backlight of an LCD; we will introduce QD Tube, QD enhancement film (QDEF), QD on-chip, and QD color filter applications. We will also discuss the remaining issues in the QD-LCD backlight.
• In EL, we will discuss the device structure and operating mechanism, ways to improve the device performance, degradation issues, etc. We will also describe inkjet printing of the color pixel patterning of the QLED.

S-2: Fundamentals of Virtual- and Augmented-Reality Technologies

Wearable computing is widely anticipated to be the next computing platform for consumer electronics and beyond. In many wearable computing applications, most notably virtual- and augmented-reality (VR/AR), the primary interface between a wearable computer and a user is a near-to-eye display. A near-to-eye display, in turn, is only a small part of a much more complex system that delivers these emerging VR/AR experiences. Other key components of VR/AR systems include low-latency tracking of the user’s head position and orientation, magnifying optics, sound synthesis, and content creation. It can be challenging to understand all of these technologies in detail due to the fact that only limited and fragmented educational material on the technical aspects of VR/AR exist today. This course serves as a comprehensive introduction to VR/AR technology to conference attendees. We will teach attendees how to build a head-mounted display (HMD). Throughout the course, different components of the VR system are taught and implemented, including the graphics pipeline, stereo rendering, lens distortion with fragment shaders, head orientation tracking with inertial measurement units, positional tracking, spatial sound, and cinematic VR content creation. At the end, attendees will have built a VR display from scratch and implemented every part of it. All hardware components are low-cost and off-the-shelf; the list will be shared with attendees. For maximum accessibility, all software is implemented in WebGL and using the Arduino platform. Source code will be provided to conference attendees.

Gordon Wetzstein is an assistant professor of electrical engineering and, by courtesy, of computer science at Stanford University. He is the leader of the Stanford Computational Imaging Lab, an interdisciplinary research group focused on advancing imaging, microscopy, and display systems. At the intersection of computer graphics, machine vision, optics, scientific computing, and perception, Professor Wetzstein's research has a wide range of applications in next-generation consumer electronics, scientific imaging, human-computer interaction, remote sensing, and many other areas. Prior to joining Stanford in 2014, Wetzstein was a research scientist in the Camera Culture Group at the MIT Media Lab. He received a Ph.D. in computer science from the University of British Columbia in 2011 and graduated with honors from Bauhaus University in Weimar, Germany, before that. His doctoral dissertation focuses on computational light modulation for image acquisition and display and won the Alain Fournier Ph.D. Dissertation Annual Award. Wetzstein is the recipient of an NSF CAREER award. He has won best paper awards at the International Conference on Computational Photography (ICCP) in 2011 and 2014, as well as a Laval Virtual Award in 2005.

Robert Konrad is a fourth-year Ph.D. candidate in the electrical engineering department at Stanford University, advised by Professor Gordon Wetzstein as part of the Stanford Computational Imaging Lab. His research interests lie at the intersection of computational displays and human physiology with a specific focus on virtual- and augmented-reality systems. Konrad has recently worked on relieving vergence-accommodation and visual-vestibular conflicts present in current VR and AR displays, as well as a computationally efficient cinematic VR capture system. He received his bachelor’s degree from the ECE department at the University of Toronto in 2014, and his master’s degree from the EE Department at Stanford University in 2016.

Nitish Padmanaban is a fourth-year Ph.D. candidate in the electrical engineering department at Stanford University, supported by an NSF Graduate Research Fellowship. Professor Gordon Wetzstein advises him as part of the Stanford Computational Imaging Lab. Currently, Mr. Padmanaban is focused on optical and computational techniques for virtual and augmented reality. In particular, he has spent the last couple of years working on building and evaluating displays to alleviate the vergence-accommodation conflict.
