Special Topics of Interest on Oxide-Semiconductor TFT (OXT)
Oxide semiconductor TFTs have already occupied an important positionin the industry ﬁeld of ﬂat panel displays. Constituent materials,
fabrication processes, characteristic enhancement technology, life-time
prolonging techniques, etc. have become mature technologies. On theother hand, there is great room to improve the characteristics. All theauthors will present novel oxide semiconductor materials, new device
structures, solution processes, post-deposition processes, etc.
Moreover, they will also propose emerging applications beyond theconventional ones. Don't miss them!!

Special Topics of Interest on Quantum Dot Technologies (QDT)
This topic will cover all aspects of the science and technologies of
Quantum Dot (QD) and Quantum Rod (QR), ranging from materials
research, device structure and properties, device applications for lighting
and display, manufacturing and high color gamut of display using QD.
This topic will specialize in QD Technologies (QDT) for the purpose of9establishing a venue for revitalization in each ﬁeld.
A highlight for IDW’18 will be the development of GaN nanocolumn LED
for monolithic micro-LED displays, and the narrow band-edge emission
from chalcopyrite semiconductor quantum dots, ligand materials toenhance luminous efﬁciency and stability of perovskite quantum dots,
and recent progress of QD materials (PH-WS), applications of quantum
dot materials, high brightness nano/micro LED, energy-saving displays
and lighting devices (MEET-WS), perovskite QD technologies, lightemitting transistors with QD and the evaluation of carrier transport
properties by impedance spectroscopy method (OLED-WS) .

Special Topics of Interest on AR/VR and Hyper Reality (AR&VR)
Augmented reality (AR) and virtual reality (VR) applications employing highperformance display devices such as sensors, cameras with tracking
capabilities, and computer graphics technologies have shown signiﬁcantprogress in the past few years.
This year we have organized six oral and three poster sessions ranging
from hardware to software systems. The IDW ’18 is a venue to access theversatile state-of-the-art in AR and VR.

Special Topics of Interest on Automotive Displays (AUTO)
One of the applications of display systems is in transportation systems
including automobiles. From 2016, Automotive Displays (AUTO) was
initiated as the new Special Topic of Interest (STI) where a lot ofpresentations concerning automobile displays were given. In 2018, WSs
such as VHF, DES, INP, UXC, 3D, and PRJ will organize the AUTO. In“these sessions”, you can hear new technological presentations, forexamples, the Head-Up Display (HUD) that can give a stable display
regardless of ambient light changes, and the gesture touch display inwhich users do not have to directly touch the surface of the display.
Furthermore, ﬂight deck display development will be reviewed. This
AUTO will surely interest audiences such as users and designers ofautomobiles.

Special Topics of Interest on Wide Color Gamut and Color
Reproduction (WCG)
Thanks to rods and three color cones in our retinas, we can enjoy thehigh dynamic range and wide color gamut (WCG). We need tounderstand our rods, cones, and nerve systems, and then to develop
suitable materials, components, displays, and systems with color-gamutexpansion and color-reproduction technologies based on color/color
vision research and WCG-related standardization.
Now in its second year as a Special Topics of Interest (STI), WCG STI is
attracting more attention and the sessions have subsequently been
expanded. One oral session in LCT-WS, one poster session in FMC-WS,
and two oral and one poster sessions in VHF-WS await audiencescomposed not only of color enthusiasts but also those who just wish tolisten in. The color-related materials and displays in LCT and FMC, color
perception in VHF are not to be missed. With novel achievements incolor vision and color conversion, you are sure to ﬁnd yourself drawn into
a whole new world of color.

Special Topics of Interest on Haptics Technologies (HAP)
Haptic technologies have been attracting attention in various ﬁelds as anext-generation technology to provide new user experiences. As a forum
for discussing the integration of display technologies and haptic
technologies, we have planned the special topic of interest on haptics
display technologies, following on from the last IDW. The many invited
talks will be given by leading Japanese researchers on topics such as
human haptic perception and measurement, presentation, andmodulation of haptic information, including pseudo-haptic display
technologies for shape and human-centric ﬂexible shape haptics
technologies. In the demonstration session, participants can actually10

"experience" the technologies related to the talks.

NAGOYA
The city of Nagoya is located in the center of Honshu, the mainisland of Japan, and has good access to Tokyo, Kyoto, Osaka andall other areas. Central Japan International Airport (Centrair) is thegateway of Central Japan to the sky, and is only about 30 min.
away from Nagoya station by railway. Nagoya is famous for thebirthplace of three notable feudal lords, Oda Nobunaga, Toyotomi
Hideyoshi and Tokugawa Ieyasu. They were active persons in the
16th century. There are many heritages such as Nagoya castle,
Atsuta Shrine, Tokugawaen, and so on. In Nagoya, traditional
industries like ceramics and textiles, and today’s key industries
like automobiles, aviation, and machine tools have been developed.
The local “Nagoya-meshi” such as Hitsumabushi, Misokatsu,
Kishimen-Noodle, Misonikomi etc. differ from those of Tokyo andOsaka foods and are the great variety and unmatched originality.
The Nagoya Congress Center, with a design motif of a swan
poised for flight, is located about 6 km from Nagoya station and isaccessible from Nagoya station about 20 minutes by subway anda further 5-minute walk.

PLACES OF INTEREST
Nagoya Castle
This is a castle built in 1612 for the Owari Tokugawa Family. The
current donjon was reconstructed in 1959. The 3rd floor throughthe 5th floor were remodeled in 1997 and were used to exhibit
artifacts depicting the lives of the feudal lords and ordinary
citizens of Nagoya in those days, as well as telling the story behind
the golden Shachihoko. Access: a 5-minute walk from the“Shiyakusho” subway station.
Atsuta Shrine
The Atsuta Shrine is the 2nd largest shrine after the Ise Shrine
and about 6.5 million people visit there annually. Shogun
Nobunaga prayed for the victory of the war here and the “Nobunagabei walls” were made by him in 1560. In the Atsuta Jingu Museum,
about 4,000 articles have been collected which were donated bypeople ranging widely in class from the Imperial Family and
Shogun to common persons. Access: a 5-minute walk from MeijoLine “Jingu-Nishi” station or Meitetsu Nagoya-Line “Jingu-Mae”
station.
The Tokugawa Art Museum
The Tokugawa Art Museum is known for its collection of “Daimyo
Dogu,” the precious treasure of the Owari Tokugawa feudal lords.
The collection includes over 10,000 items such as armors andswords belonging to Hideyoshi, Ieyasu and successive feudallords of the Owari Tokugawa clan. Access: a 10-minute walk fromthe JR Ozone station.
Toyota Commemorative Museum of Industry and Technology
The Toyota Group established this museum to help people
understand the importance and wonder of “making things” andthe “originality and research” behind it, which have become harder
to see as the high technology of industries has evolved in recent
years. Access: a 3-minute walk from “Sako” station on the Meitetsu
Nagoya-Line.

G. T. Li*,**, W. Wu**, F. Zhu**, J. J. Liu**, Y. H. Meng**, S. Li**,
H. Zhou**Peking Univ., China**Shenzhen China Star Optoelect. Tech., China

We improved the NBTS stability of BCE a-IGZO TFT with COA structure by using organic PV2 layer, which is attributed to less residual H2O
molecule in the device resulting from high vapor penetration of organic
PV2. We also optimized PV1 deposition condition to achieve good
PBTS stability and uniformity.
