coordinate the information exchange between FPGAs. Compared
to the previous model, the cost is greatly reduced, and the

Published: June 2017

Composition of siloxane hybrid material (hybrimer) was
optimized to fabricate glass‐fabric reinforced siloxane hybrid
(GFRHybrimer) with high transparency and thermal stability.
Refractive index of the hybrimer was precisely controlled by
changing the phenyl precursor and adding a low refractive
index crosslinker monomer. By measuring the thermal stability
of GFRHybrimer films fabricated with a refractive index
matched using cycloaliphatic epoxy oligosiloxane (CAEO), we
obtained an optimal CAEO composition. The optimized
GFRHybrimer film showed a high transparency (90%) and good
thermal stability (1% weight loss temperature of 365 ° C). Also,
the fabricated GFRhybrimer film showed a smooth surface (Rrms
= 0.265 nm), low coefficient of thermal expansion (~14 ppm/ ° C),
and high elastic modulus (7 GPa).

Published: June 2017

We report a simple method for reducing the response time of homogeneously aligned liquid crystal (LC) cells by using two‐dimensional confinement of the LCs. We have shown that the switching speed can be increased by serval fold in in‐plane switching and fringe‐field switching cells by introducing interdigitated electrodes parallel to the LC alignment direction. We also report an interdigitated pixel electrode structure with alternating tilts for a much wider viewing angle by aligning the LCs without a pretilt. In addition to a short response time and wide viewing angle, this device allows a much larger deviation of the LC alignment direction which is essential for mass production. Moreover, LCs with negative dielectric anisotropy can be used to minimize the transmittance decrease.

To improve the properties of QD film, much effort has been put for better efficiency and stability. Also, it has been suggested that the various forms of displays utilizing the benefit of the QDs would be followed in near future.

Published: June 2017

We demonstrate the fabrication of high performance InZnSnO thin‐film transistors (TFT) with the field‐effect mobility of 25 cm2/Vs on about 10 um‐thin polyimide substrate. Back‐channel etch (BCE) process in the bottom gate configuration is employed for easy implementation of devices with shorter channel length and smaller parasitic capacitance and cost‐effective fabrication compared with devices with etch‐stop layer (ESL). For highly uniform electrical characteristics with high field‐effect mobility, InZnSnO are deposited by high density plasma (HDP) sputtering which is assisted by microwave in order to enable the thin‐film more densified compared with conventional sputtering method. The combination of HDP sputtering method for oxide deposition and BCE process provides highly uniform electrical characteristics of TFTs with high mobility and cost‐effective method for their fabrication in large area flexible substrate.

P‐14: Prevention of Indium Segregation in BCE Type InGaZnO TFTs with Titanium Source/Drain
Authors: Kim Jeong Hyeon , Kim Byoung O , Seo Jong Hyun
Published: June 2017

Electrical properties of back channel etching type amorphous Indium‐gallium‐zinc oxide thin film transistors with pure titanium and two titanium alloy electrodes were compared. Among the three electrodes, new titanium alloy shows the best TFT performance both in terms of mobility and threshold voltage and pure titanium electrode shows the worst performance. In cases of titanium electrode, indium protrusions were observed on the surface of IGZO semiconductor after source/drain back channel etching. The poor electrical performance of titanium source/drain is attributed to indium protrusions acting as electron trap sites. In this study, a new mechanism on indium segregation is proposed and effective prevention method is suggested.

Published: June 2017

The effects of thermal annealing sequence on the performance of self‐aligned top‐gate amorphous InGaZnO (a‐IGZO) thin‐film transistors (TFTs) are investigated. The TFTs annealed before the formation of gate electrode exhibit good electrical performance, however, the TFTs annealed after the formation of gate electrode show abnormal electrical performance. It is shown that the performance of self‐aligned top‐gate a‐IGZO TFTs is very sensitive to the annealing sequence. As a result, an optimized annealing process is presented and demonstrated.

Published: June 2017

In plastic OLED (POLED) displays, bottom shield metal (BSM) layer is applied to eliminate the effect of mobile charges within plastic substrate. However, this BSM causes the abnormal kink effect, which is significantly different from the conventional LTPS TFTs with LDD. In the study, we investigated the abnormal kink effect in n‐type LTPS TFTs with BSM, especially, which is contacted by source electrode. Using experiments and TCAD simulation, we confirmed and analyzed that this kink characteristic is induced by source contacted BSM and strongly dependent on Active‐Buffer layer thickness, LDD length, and BSM length.

P‐220L: Late‐News Poster: Demonstration of an Occlusion‐Capable Optical See‐Through Head‐Mounted Display
Authors: Wilson Austin , Hua Hong
Published: June 2017

Most of the state‐of‐the‐art optical see‐though head‐mounted displays lack the ability to occlude the real scene and fail to render the virtual scene in high contrast with bright surroundings. Mutual occlusion is a strong contributor to the human visual system's ability to distinguish depth information and create a seamless integration of the real and virtual world. In this paper, we present a monocular prototype of an occlusion‐capable optical see‐through head mounted display and demonstrate its mutual occlusion capability and performance in bright environments. Our design currently uses an Organic LED (OLED) microdisplay coupled with a Liquid crystal on silicon (LCoS) type Spatial Light Modulator (SLM) to achieve a 30 degree diagonal FOV and 1920x1080 color resolution.

Published: June 2017

Efficient vacuum‐free‐processed quantum dot light‐emitting diodes (QLEDs) are reported in this paper. By printing liquid metal cathodes, vacuum‐free‐processed QLEDs exhibit a high current efficiency of ~60 cd/A and a maximum external quantum efficiency (EQE) of 14.8% for green devices, which are about 1.4‐fold higher than 42.5 cd/A (EQE 10.6%) for the devices with thermally evaporated Al cathodes. The improved performance is attributed to the reduction of electron injection caused by the GaOx thin film, which serves as an electron‐blocking layer, and thus improves the charge balance. The EGaIn based solvent‐free liquid metals are promising printable electrode materials for roll‐to‐roll manufacturing efficient QLED displays.

P‐169: Solution‐processed Organic Light‐emitting Diodes with a Polymeric Hole Transport Layer Crosslinked by Surface Initiated Oxidative Crosslinking
Authors: Jeon Sang Kyu , Lee Jun Yeob
Published: June 2017

A surface initiated oxidative coupling method of a carbazole
compound was used as a fabrication approach of a crosslinked
hole transport layer for solution processed organic light‐emitting
diodes. The surface initiated oxidative coupling method was able
to avoid damage by the organic solvent in the manufacturing
process. Moreover, the hole transport material was able to
prevent exciton quenching by the oxidizing agent and solved the
problem of luminous efficiency reduction of the organic light
emitting device because the oxidant was not in contact with the
emitting layer. As a result, the surface initiated oxidative
crosslinking method improved the luminous efficiency and lifetime
characteristics of the solution processed organic light‐emitting
devices.
