In part one, Jae Kyeong Jeong will present a concise course covering the fundamental principles of thin-film transistor (TFT) device physics and fabrication processes. The primary focus will delve into the rationale behind material selection, device architectures, and strategies for enhancing the performance of oxide TFTs. Additionally, the session will explore the essential unit processes and integration techniques used in the established low-temperature polysilicon (LTPS) TFTs. A comparative analysis between LTPS and oxide TFTs will be provided, highlighting their respective advantages and limitations. This discussion will offer valuable insights into the emerging low-temperature polycrystalline oxide (LTPO) technology. Finally, the presentation will address the underlying mechanisms responsible for device instabilities, including carrier trapping, hot carrier injection, and joule heating. 

In part two, Seung Hee Nam will introduce various thin-film transistor (TFT) devices, processes, and characteristics used in OLED display experiments and fabrications.

S-2: Organic Light Emitting Diodes – State-of-the-Art and New Frontiers for the Display Industry and Beyond

Malte C. Gather

Professor
University of Cologne, University of St. Andrews

As solid-state light sources based on amorphous organic semiconductors, organic light-emitting diodes (OLEDs) are now widely used in modern smartphone displays and TVs. The molecular nature of organic semiconductors means that the entire arsenal of organic chemistry is available to enhance and tune the properties of OLEDs. In addition, the materials used in OLEDs have an amorphous morphology and can be processed by thermal evaporation in high vacuum or even be printed. This opens possibilities to tailor and optimize device performance through stacking of different materials and numerous types of optical optimization. It also allows direct and monolithic integration of OLEDs on a vast variety of substrates, from large glass panels with TFT backplanes to silicon chips and mechanically flexible plastic films. This compatibility with different substrates sets OLED technology apart from most other lighting technologies and has been crucial to their success in the display industry. 

 

This course will review the basic properties of OLEDs, the material classes currently being developed for the next generation of even more efficient OLED displays, and methods for device fabrication in an R&D environment. Specific focus will be on optical considerations, including characterization of overall efficiency, optimization of outcoupling efficiency and spectral characteristics, and the importance of transition dipole orientation. Time permitting, emerging applications of OLEDs in the biomedical arena will also be discussed. 

 

Malte C. Gather is Humboldt Professor and founding director at the Centre for Nano- and Biophotonics at University of Cologne and holds a co-appointment at University of St Andrews. His research interests are at the interface of photonics and material science, with particular focus on OLEDs and light-matter coupling, and applications of these to information displays and biophotonics. He studied physics and material sciences at RWTH Aachen University and Imperial College London and received his PhD from University of Cologne in 2008. He previously worked at University of Iceland, Harvard University, TU Dresden and University of St Andrews.

S-3: Waveguides for Mixed Reality: Principles and Applications

Andreas Georgiou

Independent Consultant

Reality Optics, Ltd.

Future mixed-reality headsets will undoubtedly use waveguides to achieve a spectacle form factor and, if required, optical see-through. Mixed-reality waveguides were unheard of 10 years ago but are now receiving billions of dollars in investment. This course will present the operating principles for diffractive and reflective waveguides and give examples of their use in existing MR products. The gratings theory is described for diffractive waveguides, emphasizing the k-space representation. Different grating technologies are then presented, including Volume Bragg Gratings (VBGs), Surface Relief Gratings (SRGs), and Polarization Gratings. Reflective waveguides are also described, including their manufacturing methods, advantages over diffractive waveguides, and shortcomings. Finally, the operation of a few existing waveguide-based headsets is described. At the end of the course, the attendee will understand the primary function of the waveguide as a combiner and an exit pupil expander and learn the different approaches to creating one. 

Andreas Georgiou is an independent consultant with Reality Optics, Ltd., with a particular interest in computational problems in optics. He has worked in diffractive optics for over two decades and over a decade in mixed-reality optics. Georgiou enjoys innovating with head-mounted displays, three-dimensional displays, and sensors by combining physics, mathematics, engineering, and software. Before his current position, he has worked with many product groups at Microsoft (Surface, HoloLens, Azure, and Kinect), developed micro-confocal endoscopes for surgery, designed space instruments for Mars, and developed the first truly holographic display. He obtained his Ph.D. in optics from the University of Cambridge and is also an engineering research fellow at Robinson College, Cambridge. He has over 30 patents and over 20 peer-reviewed publications on head-mounted displays, data storage, holographic displays, and data transmission.

Following decades of research and development, quantum dots (QDs) have now become a mainstay of display technology. The power and utility of QDs relies on quantum size effects, which emerge as a material is shrunk to nanoscale dimensions and open an entirely new toolbox to control the absorption and emission of light. Based on this precise control, QDs can deliver unrivaled display brightness, color volume, and responsiveness across a wide variety of platforms and formats. This short course presentation will cover the basics of QD operation from physics to chemistry to optics, discuss the ways these materials can be optimized to perform in specific display applications, and finally address continued areas of research to unlock the displays of tomorrow. 

 

Ilan Jen-La Plante is a senior staff scientist at Nanosys, where she leads photoluminescent quantum-dot (QD) materials development. As a member of the R&D team since 2016, she has contributed to many of Nanosys’ commercial technologies, including the development of bright and narrow heavy-metal free QDs for QD enhancement film technology, highly absorptive QDs for QD color conversion, and QD encapsulation methods to enable operation without external gas barrier films. In addition to her work at Nanosys, she has studied QD nanomaterials at the University of California, Berkeley, Ben-Gurion University of the Negev, and Columbia University where her research has resulted in >30 peer-reviewed publications and >10 patent applications (six granted).

 

Carissa Eisler is an assistant professor in the Chemical and Biomolecular Engineering Department at UCLA.
