Yu-Wei Chang;Kuo-Chung Chu;Jung Han;Zhao-Jun Liu;Jia-Min Shieh;Hao-Chung Kuo;Chin-Wei Sher
In this study, colloidal quantum dots (QDs) were loaded into nanoporous Gallium Nitride by ink jet printing method. A full color micro LED array can be demonstrated by NP GaN. The novel and efficient method proposed here can accelerate color conversion microLED development by increase uniformity and efficiency.

Automatic Machine Vision for Mura Detection in Organic Light-emitting Diode Display
Chih-Yu Chu;Chieh-En Lee;Po-Yuan Hsieh;Jian-Jia Su;Chung-Hao Tien
The organic light-emitting diode (OLED) display unavoidably suffers from the uneven brightness phenomenon due to the manufacturing process, called Mura. In this work, we proposed an automatic detection algorithm via machine vision and human perceptual model. Proposed methodolgy successfully detect Mura in comparsion with current human on-line inspection.

Development of Anti-UV Structures for OLED Displays
Kai-Chen Lin;Yu-Hsing Lin;Bo-Kai Wang;Wei-Kai Lee;Hsien-Hung Chen;Yi-Hwa Song;Li-Wei Shih;Chung-Chih Wu
Strong resistance against solar/UV illumination induced degradation is a critical requirement for emerging and increasing outdoor, wearable, and vehicular applications of OLED displays. Here we report the development of effective anti-UV/HEV, high-transmittance structures for OLED panels based on modified DBR structures composed of UV-absorbing and dielectric materials.

a-IGZO Thin-Film Transistor-Based Differential Amplifier
Cheng-Fu Hsu;Chia-Chun Wu;Meng-Yu Ho;Feng-Yu Tsai;I-Chun Cheng
We demonstrated differential amplifiers composed of a-IGZO TFTs. The single-stage amplifier consists of differential pair and differential to single-ended conversion circuit. To improve the gain, active-load common-source amplifier is added to form the two-stage differential amplifier. The achieved voltage gain and cut-off frequency are 30.8 dB and 358 Hz, respectively.
