SUNDAY SHORT COURSES


   2020 Program

   2020 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-4: Fundamentals of High-Efficiency/Long-Lifetime OLEDs

Byung Doo Chin will describe emerging technologies in the progress of organic light-emitting diodes (OLEDs), with special focus on the evolution of high-efficiency device performance. In spite of significant progress in many up-to-date features of flexible and large-area OLEDs, there still exist some critical issues to be resolved; for example, a stable and high-efficiency blue OLED and reliability in solution OLEDs. Therefore, related topics toward a development of novel materials and other aspects will be discussed in detail. This first part of the short course will also examine the issues of flexible device manufacturing with some future advancements, as well as the impact of light extraction for OLED display panels.

The second half of this short course will address the short operational lifetime of OLEDs, which by far has been the most critical and challenging issue in OLED R&D over the years. Jaesang Lee will introduce the current status of OLED lifetimes and the importance of long lifetimes from the product perspective. He will then explore the physical and chemical origins of OLED degradation derived from experimental and theoretical studies. The degraded by-product, or defects, in aged OLEDs are a determining factor in reducing device performance and may provide useful clues to understanding degradation mechanisms. Analysis of OLED defects and lifetime improvement strategies will be discussed.

Byung Doo Chin is a professor in the polymer science and engineering department at Dankook University, Korea. He received his B.S. from Yonsei University, and his M.S./Ph.D. degree from KAIST. Before joining Dankook University in 2009, he worked as a postdoctoral scientist at University of Massachusetts Amherst, and as a senior engineer at Samsung SDI R&D Center and Korea Institute of Science and Technology (KIST). His research fields for the past 18 or more years (with about 80 research papers) include AMOLED front-plane device physics and fabrication processes, quantum-dot light-emitting devices patterned by inkjet/nozzle printing, and light-extraction structures for flexible OLEDs.

S-5: Fundamentals of Micro and MiniLED Displays

In the first part of this short course, Chien-Chung Lin will focus on the physics of the light-emitting diode and the effects of miniaturization. The elements of micro/miniLED displays will be discussed and current trends and new developments revealed.

In the second part of the course, Keon Jae Lee will introduce flexible vertical GaAs/GaN microLEDs on plastic substrates using anisotropic conductive film (ACF), resulting in high optical power density. The superior properties of the flexible inorganic LED enable the dramatic extension of flexible displays toward not only wearable devices of light sources but also full-color flexible microLED displays for consumer TVs. Also discussed will be microLED stimulation of specific neural populations of the brain, one of the facile and reliable methods used in neuroscience for deduction of functional movement, complex behavior, and even long-range connectivity. Results show how a flexible LED can be used in implantable biomedical applications such as skin research and phototherapy.
