    Abstract: 相較於傳統發光二極體(Light-emitting diode, LED),微型發光二極體(micro LED)因具有高解析度、高對比、高色彩飽和度、反應速度快及壽命長等特性,逐漸成為未來發展的重點項目之一,其相關研究也隨之備受關注。Micro LED屬於結合多領域的科技產品,為此,於元件製造前若能有效的模擬其溫度分佈與效能,將有助於後續元件整體規畫,而能降低製造成本。
    ;Compared with traditional light-emitting diodes (LEDs), micro light-emitting diodes (micro-LEDs) have the higher resolution, higher color saturation, longer lifetime, and a higher contrast ratio. Hence, this study will focus on micro-LED for more analyses on the overall chip-design to reduce the manufacturing costs.
    The purpose of this research is to establish a complete model simulating semiconductor characteristics and the electro-thermal coupling effects for the flexible micro LEDs. The model is constructed via the simulation software, COMSOL. Furthermore, a three-wall structure is investigated via three parameters, including wall-spacing, thermal conductivity, and thickness of the substrate, to know their effects on the quantum-well temperature. According to the simulation results, the quantum-well temperature can be reduced by increasing the thermal conductivity of the substrate, the thickness of the substrate, and the wall-spacing.
