Transparent Antenna for Automobile Developed
A research team led by Prof. Jae-Woo Park of the School of Electrical Engineering & Computer Science, KAIST, developed a transparent antenna for the next-generation automobiles, university authorities said on Monday (Aug. 17).
The development was made possible through joint researches with the Hyundai-Kia Automotive Group; Winncom, a car antenna manufacturer; and a group of researchers led by Han-Ki Kim of the Department of Display Materials Engineering at Kyung Hee University in Seoul.
The transparent antennas were developed in two kinds -- one for the HSDPA (High-Speed Downlink Packet Access), a new protocol for mobile telephone data transmission, and the other for transmitting and receiving radio wave for emergency call.
Using the transparent electrically conductive film formation technology, the transparent antennas are to be mounted on the windshield of a vehicle.
"The development of transparent antenna represents a step forward for the advancement of the next-generation automotive electronic technology," said Seong-woo Kim, a senior researcher at the Hyundai-Kia Group.

Prof. Choi Unveils Method to Improve Emission Efficiency of OLED
A KAIST research team led by Prof. Kyung-Cheol Choi of the School of Electrical Engineering & Computer Science discovered the surface plasmon-enhanced spontaneous emission based on an organic light-emitting device (OLED), a finding expected to improve OLED"s emission efficiency, KAIST authorities said on Thursday (July 9).
For surface plasmon localization, silver nanoparticles were thermally deposited in a high vacuum on cathode. Since plasmons provide a strong oscillator decay channel, time-resolved photoluninescene (PL) results displayed a 1.75-fold increased emission rate, and continuous wave PL results showed a twofold enhanced intensity.
"The method using surface plasmon represents a new technology to enhance the emission efficiency of OLED. It is expected to greatly contribute to the development of new technologies in OLED and flexible display, as well as securing original technology," Prof. Choi said.
The finding was published in the April issue of Applied Physics Letters and the June 25 issue of Optics Express. It will be also featured as the research highlight of the August issue of Nature Photonics and Virtual Journal of Ultrafast Science.

International Workshop on Flexible Displays Held on Aug. 21-22
An international workshop on flexible displays will be held at KAIST on Aug. 21-22.
The workshop organized by Center for Advanced Flexible Display Convergence (CAFDC) in KAIST is designed to share ideas on the latest research developments and explore future trends in organic displays. Organic displays made from organic light-emitting diode (OLED) materials have recently made a real impact in consumer electronics and emerged as one of the most important technologies in the development of next-generation flexible displays.
"The workshop is expected to provide an important opportunity to showcase latest technological developments using organic light-emitting diode and examine them from the perspectives of the next-generation flexible display," said Dr. Kyung-Cheol Choi, KAIST professor of electrical engineering and computer science who heads the CAFDC.
The event will feature some of the world-renowned scholars in organic display including Prof. Stephen R. Forrest of the University of Michigan, Prof. Bernard Kippelen of Georgia Tech, and Prof. Takao Someya of the University of Tokyo, as theme presenters. It will also draw a slew of domestic scholars in the industry and academia.

Home-Grown Transparent Thin Film Transistor Developed
KAIST, Aug. 6, 2008 -- A KAIST research team led by Profs. Jae-Woo Park and Seung-Hyup Yoo of the Electrical Engineering Division has developed a home-grown technology to create transparent thin film transistor using titanium dioxide., university authorities said.The KAIST team made the technological advance in collaboration with the LCD Division of Samsung Electronics and the Techno Semichem Co., a local LCD equipment maker. Transparent thin film transistor continues to enjoy a wealth of popularity and intensive research interest since it is used in producing operating circuits including transparent display, active-matrix OLED (AMOLED) display and flexible display.
The new technology is significant in that it is based on a titanium dioxide, the first such attempt in the world, while the technologies patented by the United States and Japan are based on ZnO.
Researchers will continue to work on securing technological reliability and developing a technology to mass-produce in a large-scale chemical vapor deposition equipment for the next couple of years.
"The development of technology to produce transparent thin film transistor will help Korean LCD makers reduce its dependence on foreign technologies, as well as maintain Korea"s status as a leader of the world"s display industry," said Prof. Park.
KAIST has applied for local patent registration of the technology and the process is expected to complete by this October or November. International patents have been also applied for in the U.S., Japan and Europe.
The new technology was introduced in the latest edition of the Electron Device Letters, a journal published by the Institute of Electrical and Electronics Engineers or IEEE, a New York-based international non-profit, professional organization for the advancement of technology related to electricity. It will be presented at the International Display Workshop 2008 on Dec. 5 in Niigata, Japan.

Youngseok Son and Yongjoon Chun won a prize of Commerce, Industry and Energy Minister
Youngseok Son and Yongjoon Chun, doctorate students at circuit design and system application lab of Electrical Engineering Division, won a prize of Commerce, Industry and Energy Minister (Silver prize) at the 7th Semiconductor Design Contest hosted by the Korean Intellectual Property Office.
Their work exhibited at the contest is ‘a driving circuit for the improvement of image quality of AMOLED display’.
AMOLED display is gaining attention as a next-generation display for its numberless advantages compared to AMLCD and PDP, however, problems over the image quality and lifespan of the display have disturbed the substantial development. Their work verified its electrical features by proposing and designing the driving method and circuit for the improvement of the image quality and lifespan of AMOLED display. The announced driving method was named ‘Transient Cancellation Feedback (FCF)’ and its concept was published in SID 2006. Their work was evaluated to overcome the limitation of the existing driving methods by providing an intrinsic Active Matrix structure, different from the existing driving methods.
It is also evaluated to strikingly enhance the speed and accuracy of data current driving through TCF driving. It is expected to significantly enhance the image quality and lifespan of AMOLED displays by applying TCF driving.
