| dc.description.abstract | 可撓式有機發光二極體(Flexible organic light-emitting diodes, FOLED) 是具潛力的顯示器以及照明元件，然而，其因壽命表現不佳而未能全面市場化。本研究提出一改善之軟性基板，供予可撓式有機發光二極體使用，以提升其散熱能力，進而延長元件之壽命。本研究藉由模擬分析、元件量測、光學原理以及熱學原理，成功推估並驗證該改善之軟性基板的散熱提升效益，其延長一般可撓式有機發光二極體之壽命為1.67倍。再參照市面上實際的顯示器產品之尺寸，模擬大尺寸模型之熱分布，進一步推估該改善之軟性基板應用於現今大型顯示器之可行性。本研究之成果將作為未來大型FOLED壽命提升的實作之參考 | zh_TW |
| dc.description.abstract | In this study, we propose a methodology to enhance the lifetime of flexible organic light-emitting diodes (FOLEDs). By means of improving the thermal conduction on the substrate, we can increase the efficiency of thermal dissipation of the FOLED and optimize its lifetime. Using self-developed model in simulation software, COMSOL, and Arrhenius equation, we estimated the lifetime firstly. Next, we measured luminance and thermal distribution of a small-area white FOLED via a luminometer and a thermographic camera. After the comparisons between simulation and measured results, we corrected the constructed model. Furthermore, we predicted the lifetime of large-area OLED lighting panels. This proposed substrate is expected to extend the lifetime and to improve OLEDs’ performance obviously. | en_US |
