有機發光二極體(OLED)的研究近年來被受關注，在元件製程前若能有效的模擬預測其效能，必能對材料的選擇上有更多分析及有效的降低製程成本。然而，建構一套模擬系統仰賴著元件的各項分析實驗，藉由量測材料的特性回饋至模型才能更準確的表現其元件特性，且利用實驗驗證模擬結果也有助於日後的誤差分析。 本論文使用COMSOL建構一套OLED的三維熱模型，並且利用暫態熱阻量測法測出有機層的熱阻參數，代入熱模型中模擬出實際OLED元件的表面熱分布。為了驗證此熱模擬，本研究建構了一套熱分布的量測系統，其利用熱電耦及熱影像儀，量測出實際元件的熱分布，以便與熱模擬結果比對。接著利用元件的量測結果進行OLED能量轉換的分析，其使用輝度計量測元件的出光表現，並將之與溫度量測結果分析比較，以探討其能量轉換的趨勢。 ;In recent years, more and more researchers have paid attention to the OLEDs. If the characteristics of an OLED device can be simulated before fabrication, it will be helpful for selecting materials and reducing manufacturing costs. However, to establish a simulation system relies on multiple experiments, such as measuring the characteristics of the material. The measured results are used as feedback for improving the accuracy of the simulation model and also helpful for further erroneous analyses. In this study, we built a three dimensional thermal simulation model by the software of COMSOL Multiphysics and used transient thermal resistance measurement method to measure the thermal resistance of the organic layer. By means of our thermal model, the temperature distribution on an OLED device can be simulated. In order to verify this thermal model, we constructed a system by using a thermocouple and a thermal imager to measure the actual temperature distribution of OLEDs. Meanwhile, we measured the luminous performance of OLEDs and compared it with the measured temperature distribution to know the energy conversion trend.
