High-quality, wide viewing angle autostereoscopic LCD display with directional backlight, hybrid spatial- temporal-control and optimized system design with genetic algorithm.
Jian-Ying Zhou,

A directional backlight based autostereoscopic display system with a hybrid spatialand temporal-control is demonstrated to have a number of distinct advantages over conventional lenticular- or barrier based autosteresocopy. The optical design of the system is based on the optimized figure of merit, a new definition for autostereoscopic display. Low cross talk, homogeneous viewing effect are all made possible with the optimized design. Wide viewing angle is demonstrated with a specially tailored backlight arrangement, and extension of z-viewing distance is also proposed and demonstrated.

Jian-Yu Wang Award Candidate Enhanced Stress Reliability of a-IGZO TFT by Dual-Channel-layer Structure
Jian-Yu Wang,Zingway Pei,Hsin-Cheng Lai,Chien-Hsun Chen,

In this study, we reported amorphous indium gallium zinc oxide (a-IGZO) thin film transistor (TFTs) with a single-source double-layer concept processed on a glass substrate. The Al2O3 layer for gate dielectric material was deposited by atomic layer deposition (ALD). The a-IGZO TFT exhibit mobility of around 14.4 cm2/Vs. The mobility could be further increase by fine tuning the a-IGZO deposition condition. This technology is suitable to integrate into LCD or OLED implementing display.

Kuan-Hsun Wang Award Candidate Deep ultraviolet annealing and patterning for sol-gel InGaZnO TFT
Kuan-Hsun Wang,Hung-Cheng Lin,Stehlin Fabrice,Hsiao-Wen Zan,Olivier Soppera,Chang-Hung Li,Fernand Wieder,Bo-Hung Yeh,

A IGZO precursor solution was developed to fulfill the requirements for direct photopatterning at micro and nanoscale and for achieving semi-conducting properties with DUV annealing at moderate temperature. The effect of DUV annealing was investigated. The process opens the door towards low-cost large-area technology.

Mao-Hsiu Huang Award Candidate Object Images Quality Improvement For Transparent Displays With Different Array Structure Of AMOLED
Mao-Hsiu Huang,Yu-Hsiang Tsai,Wei-De Jeng,Ting-Wei Huang,Mang Ou-Yang,

In transparent display, when object light passes through the edge of transparent region, diffraction would cause image blur on the edge of the object image. In this paper, diffraction effect of transparent type active-matrix organic light-emitting diode (AMOLED) was simulated, and used different transparent types of pixels to reduce the diffraction effort. After simulating the array structure, 43% diffraction width in X direction and 30% diffraction width in Y direction can be reduced in the transparent type processed by stagger.

Zi-Yang Huang Award Candidate The simulation and reduction of display moiré with digital image processing technique
Yu-Lin Tsai,Zi-Yang Huang,Chi-Fu Chang,Chung-Hao Tien,

The objective of this paper is to analyze and eliminate moiré image arising from the liquid crystal display (LCD). The analysis and judgment of moiré degradation is based on Fourier transformation and human vision systems. The elimination of moiré behavior is to search optimum solution in the searching space through the particle swarm optimization (PSO). The verification result shows that moiré pattern can be predicted and judged. The moiré free range can be found by PSO in the design example.
