Yi Lin Tsai Award Candidate Study of Image sticking of liquid crystal cell with dielectric spectrum
Yi Lin Tsai,Chi Yen Huang,Ching Yu Chen,Chun Ying Huang,

We investigate dielectric spectrum (DS) of the liquid crystal (LC) cell. The obtained result reveals that the DS of the LC cell after DC stress is shift to the low frequency region. After stress, the DS of the LC cell is restored to the original position before DC stress. Furthermore, the restoring speed of the LC cell with image sticking is slower than that of the LC cell without image sticking.

Shang Yi Chih Award Candidate Liquid Crystal Lens with Double Hole-patterned Electrodes
Shang Yi Chih,Che Ju Hsu,Chi Yen Huang,

We fabricate the liquid crystal (LC) lens with two hole-patterned electrodes. The two hole-patterned electrodes have different aperture diameters, which effectively solve the disclination line of the LC lens with large diameter. In addition, the demonstrated LC lens with two-hole patterned electrodes has the features of coaxial dual focal lengths and aperture switching function.

Chao-Jui Hsu Award Candidate Room-Temperature-Processed Flexible n-InGaZnO/p-Cu2O Heterojunction Diodes and High-Frequency Diode Rectifiers
Chao-Jui Hsu,Wei-Chung Chen,Po-Ching Hsu,Chih-Wei Chien,Kuei-Ming Chang,Ching-Hsiang Chang,Wei-Kai Lee,Wen-Fang Chou,Hsing-Hung Hsieh,Chung-Chih Wu,

We report successful implementation of room-temperature processed flexible n-InGaZnO/p-Cu2O heterojunction diodes on plastic substrates by sputtering technique. The flexible didoes exhibited a ideality factor of 1.4. The frequency response of the flexible diode rectifiers indicated high-frequency operation up to 27 MHz. These characteristics indicate promise for applications in flexible electronics.

Yuan-Di Chen Award Candidate Optically and thermally alignment switch of liquid crystals cell coated with poly(N-vinylcarbazole) films
Yuan-Di Chen,Yu-Wen Tsai,Yen-Chen Liu,Ko-Ting Cheng,Andy Ying-Guey Fuh,

We study liquid crystal (LC) cell coated with poly(N-vinylcarbazole) (PVK) film under the exposure of ultraviolet (UV) light irradiation and temperature effect. UV exposure time is a key to determine the temperature required starting the switch of LCs alignment. Based on this effect, a TN grating is produced.

Jia-Hong Hsu Effects of Incorporating Salts with Various Alkyl Chain Lengths on the Recombination Zone Position of Light-Emitting Electrochemical Cells
Ray Sun,Chih-Teng Liao,Jia-Hong Hsu,Hai-Ching Su,

When doped with salts possessing proper sizes, nearly doubled device efficiency can be obtained due to improved carrier balance. It demonstrates a feasible strategy to improve device performance of light-Emitting electrochemical cells (LECs) and clarifies the physical insights of the effect of salt size on carrier balance of LECs.

Yi-Hsin Chen IGD Circuit In-Line Inspection on TFT Array Panel
Y. C. Wang,B. S. Lin,M. C. Chan,Yi-Hsin Chen,

In past, it cannot detect flaw in integrated gate driver circuit on thin-film-transistor array panel. We proposed in-process inspection with electro-optical measurement for that. The paper resulted a successfully inspection for the flaw on which including line defects and critical point defects in integrated gate driver circuit.

Chia-Yu Wu Coatable Circular Polarizers for Flexible OLED Display
Chia-Yu Wu,Mei-Chih Peng,Kuo-Chang Lee,Pao-Ju Hsieh,Kai-Sheng Shih,Yu-Chun Lin,

In this paper, a study of the manufacturing method and optical performance of the coatable circular polarizer was reported. The reflectance and viewing angle characteristics are close to the commercial product. By which, a feasible way to enhance the contrast of the display in ambient light condition was proposed.
