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, start-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 |
With the rapid advances in real-time 3D sensing, perceptual computing, and immersive display technologies in recent years, a new class of virtual/augmented/mixed/merged reality (VR/AR/MR) devices is increasingly blurring the border between the real and the virtual words. In this short course, we will present a tutorial of these technologies and applications, covering the system-level requirements from psychophysical and human-factors considerations, the advances in 3D motion tracking with visual-inertial sensing techniques, perceptual computing and graphics processing, spatial-light modulation and display technologies, end-to-end system architectures, and state-of-the-art and emerging applications towards achieving life-like immersive and interactive experiences.
Achin Bhowmik is the chief technology officer and executive vice president of engineering at Starkey, which is the largest hearing technology company in the US. Starkey is a privately held medical devices business with more than 5,000 employees and operations in more than 100 countries worldwide. In this role, he is responsible for leading the company’s research and engineering efforts. Prior to joining Starkey, Dr. Bhowmik was vice president and general manager of the Perceptual Computing Group at Intel Corporation. There, he was responsible for R&D, engineering, operations, and businesses in the areas of 3D sensing and interactive computing, computer vision and artificial intelligence, autonomous robots and drones, and immersive virtual and merged reality devices. Previously, he served as the chief of staff of the Personal Computing Group, Intel’s largest business unit.
As an adjunct professor and guest lecturer, Dr. Bhowmik advises graduate research and teaches courses on human-computer interactions and perceptual computing technologies at the University of California, Berkeley, Stanford University, Liquid Crystal Institute of the Kent State University, Kyung Hee University, Seoul, and the Indian Institute of Technology, Gandhinagar. Dr. Bhowmik was elected as a Fellow of the Society for Information Display (SID). He serves on the board of advisors for the Fung Institute for Engineering Leadership at UC Berkeley, the executive board for SID, and the board of directors for OpenCV. He received the Industrial Distinguished Leader Award from the Asia-Pacific Signal and Information Processing Association. He has over 200 publications, including two books and 34 issued patents.

S-3: Fundamentals of Flexible OLEDs and Manufacturing of Flexible OLEDs |
Professor Jang Hyuk Kwon will describe flexible OLED materials and device structures based on the industrial activities aiming for flexible AMOLEDs. The critical aspect of OLED materials, flexible substrates, flexible films, OLED structures, and thin-film encapsulation technologies will be emphasized. We will address the basic principles of flexible AMOLEDs and discuss the current technical status of challenging technologies based on flexible material and device structure viewpoints.
Professor Min Chul Suh will describe how to manufacture flexible AMOLEDs. For example, we will cover various topics related to materials and processes such as flexible substrates, flexible film handling techniques, OLED pixel-forming technology, thin-film encapsulation technology, etc. We will also discuss the current technical status of challenging technologies based on flexible electronics.
Jang Hyuk Kwon is a professor in the Department of Information Display at Kyung Hee University in Seoul, Korea. He received his Ph.D. in 1993 in chemistry at the Korea Advanced Institute of Science and Technology. He started his first job working with display R&D at Samsung SDI. He was an original member of the OLED team at Samsung. He has also been involved in many OLED and AMOLED projects, many of which are slated for future displays. He was especially honored to be the leader in charge of the set-up of OLED device and material technology for manufacturing at Samsung.
