Abstract:	有機發光二極體(OLED)近年來蓬勃發展，在面板顯示與照明應用領域逐漸被重用，其相關研究也隨之備受關注。OLED是個結合許多領域的科技產品，因此，在元件製造之前若能有效的模擬其效能，對元件製作的整體規劃必定能有更多的分析以降低製程成本。而藉由輸入真實材料特性於模擬模型，以及以實驗量測元件效能，將可修正模型參數並驗證模型，使模擬系統準確度更高。本論文目的為建立一套適用於OLED元件光熱電整合的模擬，並藉由實驗量測元件以驗證此套模擬是準確可行的；在此處使用COMSOL軟體先建構一套OLED三維的光模型，藉由設定幾何尺寸、各層材料折射率以及邊界條件，模擬OLED元件的出光效能，再結合本實驗室已建置之熱電模擬技術，藉由電功率能量轉換的比例分配，來達到光熱電模擬整合的目的。為了驗證此光熱電模擬系統，本研究利用相關光學儀器量測實際元件的出光效能，與光模擬之結果做比對，並修正模型參數，更利用熱影像儀，實際量測元件的熱分布，與熱模擬之結果做比較。最後，將此兩部分結果分析比較，探討元件電功率的能量轉換比例，以確定模擬模型之準確度。;With the development of solid state lighting in recent years, OLED has gradually been prevalent in display and lighting applications. If the performance of an OLED device can be simulated before the fabrication, it will be helpful for planning the manufacture and reducing the costs. By importing the given characteristics of the materials into the simulation, we can analyze the OLEDs through the simulated and experimental results and prove the accuracy of the simulation model. In this study, we built a three dimensional photo-electro-thermal simulation model by the software, COMSOL Multiphysics. First, we constructed the optical model and assigned the related parameters. After receiving the simulated out-lighting results, we combined the optical model and the pre-built electro-thermal model by the ratio of energy. This combined model can simulate not only the luminous performance but also the temperature distribution of the element. In order to verify the simulation model, we measured the luminous performance and temperature distribution by using instruments, such as the integrating sphere, the lux meter and the thermal camera. Finally, we compared the simulated and experimental results to prove the accuracy of the simulation model and discussed the energy ratios in the optical and electro-thermal models according to the energy conversion theory.
