可應用於微發光二極體之可撓式高導熱基板技術

Project Details

Description

he Micro-LED technology becomes a hot topic in resent display and lighting research fields. Meanwhile, some international companies gradually develop and hold its key techniques. However, the flexible Micro-LED is at the budding stage. The flexible Micro-LED can be applied to wearable displays, biosensors, monitoring and stimulating devices for the medical equipment, such as the pacemaker, etc. Although the flexible Micro-LED is an awaited device, it faces two challenges: the induced strain-issue and the low heat-dissipation efficiency due to the flexible substrate. Since most flexible substrates are made of plastics with the heat conductivity less than 5 W/mK, they will cause the much heat to accumulate inside the devices, resulting in the quantum efficiency and the shorten lifetime. Thus, this research project focused on the technology of flexible Micro-LED and dealt with the issue of heat-dissipation. Our group, based on the experiences over the optical-thermal and electrical integrated modeling of OLED, as well as the researches on flexible OLED, developed the electro-thermal modeling techniques for flexible Micro-LED in this project. Also, we designed and fabricated a high thermal-conductive flexible substrate by doping technique. The verified electro-thermal modeling and the fabrication of high thermal-conductive flexible substrate both benefit the thermal dissipation and the performance of the flexible Micro-LEDs.
