dc.description.abstract | 在有機發光二極體(OLEDs)顯示應用當中,高效率白光有機發光二極體可搭配彩色濾光片而實現大面積與高解析度,或是作為背光及照明光源等等。若採用堆疊串接式結構之OLED元件,在相同亮度下,可降低所需之操作電流,或者在相同操作電流下提高亮度,對於OLED操作壽命與可靠度之增進具有顯著效果,適合應用於高亮度或是省電的產品。本篇研究期望藉由光學模擬與元件結構設計,包括更換材料、調整各層厚度、變換發光層位置等方式,針對單一發光單元結構以及堆疊串接式結構,探討較高外部量子效率之白光OLED元件結構。
本篇論文之研究步驟大致分為製程量測實驗與模擬研究。製程方面主要使用熱蒸鍍系統製作薄膜與元件,接著透過各量測儀器,將樣品進行量測與分析,可得各有機材料之光物理特性以及元件之效能。模擬方面會將取得之光物理特性作為參數,進行元件的耦合出光效率、頻譜之光學模擬,透過計算將模擬結果轉換為外部量子效率以及色度座標,另外,量測實際元件所得的頻譜用以驗證光學模擬軟體之有效性。本論文進行了單一發光單元結構以及堆疊串接式結構白光元件之模擬設計,將優化之元件與基準元件做效率比較,以獲得最佳增進效率之元件結構。 | zh_TW |
dc.description.abstract | In organic light-emitting diodes (OLEDs) display applications, high efficiency white OLEDs (WOLEDs) can be used with color filters to achieve large area and high resolution displays, or as backlight and lighting sources. With using Tandem OLEDs, the required operating current can be reduced under the same brightness, or the brightness can be increased under the same operating current. It has a significant effect on the improvement of OLED operating life and reliability, and is suitable for high brightness or power saving products. This study aims to study the structure of WOLED devices with high external quantum efficiency (EQE) for single light-emitting unit architecture and tandem architecture through optical simulation and design, including varying materials, adjusting layer thicknesses, changing the position of the emission layer, etc.
The research steps of this study were roughly divided into experiment and simulation studies. In experiments, a single-chamber thermal evaporation system was mainly used to fabricate thin films and devices, and then samples were measured and analyzed through various instruments, and the photophysical properties of each organic material and the performance of the devices were obtained. In simulation, the obtained photophysical characteristics will be used as parameters to carry out optical simulation of optical out-coupling efficiency and spectrum of OLED devices, which would be converted into EQE and CIE coordinates through calculation. The spectra obtained by measuring the fabricated devices were used to verify the optical simulation software. The simulation studies of single light-emitting unit and Tandem WOLED devices were carried out, and the EQE of the optimized devices were compared with the reference devices to obtain the best device structures. | en |
