Red InGaN-LEDs Grown By Micro-Flow Channel MOVPE
Kazuhiro Ohkawa
The development of three primary colors (RGB) InGaN LEDs will be the key technology to realize monolithic full-color lighting and displays in the near future. We have developed micro-flow channel MOVPE that can grow high-In-content InGaN at raised temperatures of 60-100oC compared to conventional MOVPEs.

Investigation and Fabrication of All-Inorganic Solution Processed Quantum Dot Light Emitting Diodes
Hsin-Chieh Yu;Wei-Chun Liao;You-Xuan Zhao;Chih-Min Fu;Tzu-Hao Lee;Ya-Li Chang
All inorganic quantum dot light emitting diodes (QLEDs) consists of Zn(Mg)O nanoparticles electron transport layer (ETL) and NiOx hole transport layer (HTL) prepared by nanoparticles and sol-gel method were demonstrated. Operation characteristics of the fabricated devices including maximum luminance (Lmax) can be up to 50,088 cd/m^2.

Suppression of Current Collapse in GaN HEMTS Using Substrate Removal
Ji-Xuan Yang;Yueh-Ting Chen;Jian-Jang Huang
Dynamic output characteristics of AlGaN/GaN/Si HEMTs are analyzed before and after the local Si substrate removal. The current collapse can be suppressed after substrate removal. If we increase the negative gate bias at pulse condition, the current degradation of conventional HEMTs will become much worse than the one without substrate.

Study and Package of LiDAR-Embedded Smart Laser Headlight for Autonomous Vehicles
Yun-Huei Chen;Chun-Nien Liu;Zingway Pei;Yeong-Kang Lai;Pin Han;Wan-Shao Tsai;Wood-Hi Cheng
We demonstrated a LiDAR-embedded smart laser headlight module (LHM) for autonomous vehicles. This novel LiDAR embedded smart LHM with the unique highly reliable glass phosphor-converter layer is favorable for use in the next-generation high-performance autonomous vehicle applications, which were well satisfied the ECE R112 class B regulation.

GaN-based green resonant-cavity light emitting diodes with high output power
PO-HSUN TSAI;HENG LI;SHUO-YI KUO;BO-YAN CHEN;TIEN-CHANG LU
We optimize the RCLED structure by changing the p-GaN thickness, number of DBR pairs and quantum well shape. The light output power reaches the maximum of 80 mW. As the number of DBR pairs increasing, the LOP and FWHM decrease exponentially.

Efficient Hybrid Warm White Organic Light-Emitting Diode with Single-Emitting Layer of Thermally Activated Delayed Fluorescent and Phosphorescent Materials
chih wei huang;ting an lin;chen han lu;ken tsung wong;chung chih wu
In this work, we developed efficient hybrid warm white OLEDs using sky-blue TADF and orange phosphorescent emitters. SpiroAC-TRZ was chosen as the TADF blue emitter and OPH1 were chosen as the orange phosphors. The hybrid warm white OLED achieved an EQE of up to 31%
