Sapporo City
Sapporo City in Hokkaido is the northernmost city designated bygovernment ordinance in Japan with a population of around 2
million. Sapporo is known for the functional rectangular grid ofstreets and avenues as a city modeled after Kyoto. The word
"Sapporo" is originated from the Ainu (indigenous people ofJapan) language and is well known as the host city for the 1972
Winter Olympics. Dishes using local Hokkaido produce andseafood rank high amongst the many charms of Sapporo, as well
as being known for the annual snow festival and YOSAKOI SoranFestival.

Places of Interest
Odori Park
Odori Park divides the city center into north and south. It stretches
for about 1.5 km, covering 12 blocks, and the grounds around the
TV tower located there provide an oasis for people living andworking in the surrounding office district.
In every corner of the park, you will find attractions, monuments,
art work (including pieces by the famous Isamu Noguchi),play-areas, fountains, and of course the beauty of the seasonal
flowers and trees. The park is home to 4,700 trees of 92 species
such as lilacs, elms, Japanese zelkovas, azaleas and cherrytrees. Many events are held here throughout the year including theworld-famous Snow Festival.
Jozankei Onsen (Spa)
A 75-minute bus tour from JR Sapporo station takes you to one of
the largest hot springs in Japan, Jozankei. The history of Jozankei
dates back to 1866, when Miizumi Jozan, an ascetic monk, discovered the hot springs and opened a healing spa on the upper
Toyohira River. The hot spring waters that bubble out of the groundat Jozankei spa resort contain sodium chloride, which is colorless,transparent, and mildly salty. These are common qualities of thewater in Japanese spas.
http://jozankei.jp/en/
Susukino
Susukino is Japan's largest entertainment district north of Tokyo,
however it is not an official designation of any municipality. There
are said to be approximately 4,500 bars and restaurants, including
Ramen Yokocho, a narrow lane lined with shops serving
Sapporo's famous ramen.

Invited VR Headset with Human-Eye Resolution*Osku Sahlsten1
1. Varjo Technologies Oy (Finland)With current display manufacturing methods, it would be very hard to
produce a single near eye display that offers 60 pixels / degree resolution over the whole field of view and is small enough to fit into the headset. In case of greater than 90-degree field of view, basically 6k x 6k
panel would be required. With the high refresh rates of virtual reality applications, this would mean also very large data transfer rates and highrendering load on GPU´s.Varjo overcome these challenges by composing the single eye image from two different display sources, while minimizing the effect on total rendering load. High angular resolution isused on the area where it is mostly needed. Precise analysis of displays with geometrical- and optical adjustments is needed to blend the2 separate images to a one uniform scene.

Co., Ltd. (China)

In order to improve the color washout of multi-domain vertical alignment (MVA) LCD in low gray cale, a new pixel design with reduced color washout and high transmittance is proposed. In the new pixel design,
the ITO slit angles of the R/G/B sub-pixels are changed to varying degrees, and the central V-Trunk is blocked by metal. As a result, the color
washout is greatly improved (about 40%) without loss of transmittance.

contrast ratio, the picture quality reconstructed by LCD is better. LCD
module is constructed by back light and optical switch. And the LC is
not an ideal optical switch, so the contrast ratio of LCD is lower than

A novel Four-Photomask complementary metal oxide semiconductor(CMOS) technology for low temperature polycrystalline silicon (poly-Si)
thin film transistors (LTPS TFTs) was proposed in the first time. The
combination of poly-Si layer and P plus (P+) region definitions within
one lithography process was realized by a half-tone photomask. In thispaper, the characteristics of TFTs within a half-tone Poly-Si Photomask
of lithography processes were reported and compared with electricalcharacteristics of typical Six-Photomask lithography processes. The
Integrated Poly-Si Photomask Technology can be applied to reduce thenumbers of photomask of making an IGZO and LTPS Hybrid TFTs

The contrast ratio is a important index for the LCD optics. The higher
contrast ratio, the picture quality reconstructed by LCD is better. LCD
module is constructed by back light and optical switch. And the LC is
not an ideal optical switch, so the contrast ratio of LCD is lower than

This work reports the experimental research results of the retardation
change of a reactive mesogen type quarter-wave plate (QWP) by bending when the slow axis the QWP is oriented with the bending axis according to perpendicular or parallel directions. Moreover, the effect of
the retardation changes on the antireflective properties of a quasi-circular polarizer taken accounts for an organic light-emitting diode in thesimulation. Based on the obtained results, we assign that the light leakage reduced gradually with bending effect in the vertical viewing orientation, while it was increased in the horizontal viewing direction regardless of the orientation of the slow axis.

In this study, we report a significant phenomenon that EL performancesfor 3D materials, such as CsPbX3, are governed by adjacent chargetransport layers, which is possibly due to nonradiative recombination
resulting from the small exciton binding energy. To overcome this issue,
we developed a new electron transport layer (ETL) that enhances exciton confinement effect in 3D CsPbX3. Consequently, we achieved ultra-high brightness of 500,000 cd/m2 at a very small operating voltage

produce a single near eye display that offers 60 pixels / degree resolution over the whole field of view and is small enough to fit into the headset. In case of greater than 90-degree field of view, basically 6k x 6k
panel would be required. With the high refresh rates of virtual reality applications, this would mean also very large data transfer rates and highrendering load on GPU´s.Varjo overcome these challenges by composing the single eye image from two different display sources, while minimizing the effect on total rendering load. High angular resolution isused on the area where it is mostly needed. Precise analysis of displays with geometrical- and optical adjustments is needed to blend the2 separate images to a one uniform scene.

High-resolution electron microscopy requires an electron source withhigh brightness and resolution. We simulated and fabricated the carbon
nanotube (CNT) cold cathode with high resolution. For the simulation,
we used SOURCE 2D simulator and fabricated self-focused CNT
based electron beam. The beam shows micron scale resolution with
optimized self-focused CNT beam design. The beam spot size depends
on the various parameters, such as depth, width and driving conditions.

Effects on X-ray Imaging Quality by Manipulation ofCold Cathode Emitter Density*Jisoo Oh1, Yi Yin Yu1, Kyu Chang Park1
1. Kyung Hee University (Korea)

The relationship between the density of electron emitters and x-ray image quality has been investigated. Under diode mode, x-ray images
have been successfully acquired even under 30kV of bias. The electron
emitters were selectively patterned VACNTs. With respect to the inter-emitter pitch, even at the same electrical energy, different patterns
showed different image qualities. By optimizing the CNT pattern, we expect that we can develop a high-resolution x-ray source without using
additional focusing components.

Invited VR Headset with Human-Eye Resolution*Osku Sahlsten1

With current display manufacturing methods, it would be very hard to
produce a single near eye display that offers 60 pixels / degree resolution over the whole field of view and is small enough to fit into the headset. In case of greater than 90-degree field of view, basically 6k x 6k
panel would be required. With the high refresh rates of virtual reality applications, this would mean also very large data transfer rates and highrendering load on GPU´s.Varjo overcome these challenges by composing the single eye image from two different display sources, while minimizing the effect on total rendering load. High angular resolution isused on the area where it is mostly needed. Precise analysis of displays with geometrical- and optical adjustments is needed to blend the2 separate images to a one uniform scene.

A voltage range of 0 to 30V and afrequency of 12.5KHz clock signal is used for the ripple counter as input clock input. A high output level of ~27.4V and a low output level of~4 or 5V are measured at the 2nd and 3rd stages’ output node of theripple counter. Their frequencies are one quarter and one eighth of the
input signal’s frequency. The output signal of the proposed ripple counter changes when its input signal falls to low level from high.

Although organic-inorganic halide perovskites continue to generateconsiderable interest with the high potential to be widely applied in avariety of optoelectronic devices, there are some critical obstacles topractical applications such as the toxicity of lead, the relatively low field
effect mobility and the strong hysteresis during operation. Here we develop a universal approach to significantly improve mobility and operational stability, and reduce the hysteresis of perovskite-based transistors simultaneously through coupling low-dimensional lead-freeperovskite material (C6H5C2H4NH3)2SnI4 (hereafter abbreviated as(PEA)2SnI4) with embedded conjugated polymers wrapped semiconducting carbon nanotubes (semi-CNTs). In the (PEA)2SnI4/semi-CNTs
hybrid systems, semi-CNTs can contribute as smooth tracks for carriers
to transport with less scattering and trapping of perovskite grain boundaries. We also demonstrate the extraordinary performance of(PEA)2SnI4/semi-CNTs hybrid phototransistors with ultrahigh photoresponsitivity and photosensitivity, which is found to be on a par with thebest devices available to date.
