Manipulating and Enhancing Optical Performance of OLEDs with Curved and Three-dimensional Structures
Wei-Kai Lee;Zih-Rou Cyue;Po-Jui Chen;Li-Yu Yu;Hoang Yan Lin;Guo-Dong Su;Chung-Chih Wu

Making use of the advance of OLED technologies and characteristics of OLEDs, we explore and discuss the possible uses of curved and three-dimensional structures for manipulating or enhancing optical performance of OLEDs, such as light extraction, emission distribution etc.

High brightness and deep-red emission organic light-emitting diodes employing the ITO-free substrate
Chieh-Hsin Chen;Yi-Nan Lin;Chih-Chien Lee;Shun-Wei Liu

In this work, we demonstrated a deep-red emission organic light-emitting diode (OLED), which showed high brightness, low operational voltage, and low-efficiency roll-off. The deep-red emission OLED can be employed in photobiomodulation therapy (PBMT), such as wound healing, hair growing, and skin rejuvenation.

High-Efficiency Organic Light-Emitting Diodes Using High-Index Transparent Electrode
Yu-Hsin Huang;Chung-Chih Wu

This work reports the adoption of high index transparent electrode as a new avenue for greatly boosting OLED efficiency. By using the Nb-doped TiO2 electrodes with a high refractive index of 2.4, along with high-performance organic materials, a high EQE of 41.5% is realized for conventional planar OLEDs.

New Pixel Circuit with Threshold Voltage and Leakage Current Compensation Scheme for Wearable AMOLED Displays
Sung-Chun Chen;Yu-Sheng Lin;Chih-Lung Lin

This work presents an active-matrix organic light-emitting diode (AMOLED) pixel circuit for 15 Hz frame rate display applications. Simulation results show that the relative current error rates are less than 4%. Moreover, the OLED emission current fluctuations during the 66.6 ms emission period have significant improvements.

Flexible a-IGZO Thin-Film Transistor Based Differential Amplifier
YU-SHU HUANG;Cheng-Fu Hsu;Shu-Ming Hsu;Wen-Hsuan Lai;Feng-Yu Tsai;I-Chun Cheng

A flexible differential amplifier comprising 8 a-IGZO TFTs is demonstrated on polyimide substrates. It exhibits a gain of 11.6 dB, cut-off frequency of 620 Hz and CMRR of 15.3 dB. Furthermore, similar performance is observed when the flexible amplifier is inwardly and outwardly bent to a radius of 1 cm.
