| dc.description.abstract | 有機發光元件至今已經快速發展成一具有潛力的平面顯示技術，其中，主動矩陣有機發光元件以薄膜電晶體為底，能達到高品質的全彩顯示，是一個有潛力的顯示技術。為了能夠利用n型氧化物半導體薄膜電晶體的優點，希望能夠使用倒置式有機發光元件與之搭配。為了增長有機發光元件的壽命，必須設法使有機發光元件操作在低電流下仍然能有高發光亮度，因此希望製作出堆疊串接式有機發光元件。
在本論文的第一部份中，我們針對倒置式有機發光元件做深入探討。在電洞注入層方面，我們使用了新穎的有機電洞注入材料，並探討其對於元件的影響；在電子注入層方面，我們使用了數種不同的電子傳輸層材料做n型摻雜，並探討其對於元件的影響。最後，我們製作出了能與傳統非倒置式有機發光元件相匹敵的高效率、低操作電壓之磷光綠光倒置式有機發光元件。 在本論文的第二部份中，我們針對堆疊串接式有機發光元件做深入探討。我們分別使用「電洞傳輸材料/有機電洞注入材料/n型摻雜電子傳輸材料」與「電洞傳輸材料/電洞傳輸材料與有機電洞注入材料混合層/有機電洞注入材料/n型摻雜電子傳輸材料」兩種不同的載子產生層結構於堆疊串接式有機發光元件，並製作出高效率磷光綠光堆疊串接式有機發光元件，在高亮度下，堆疊串接式元件之電流發光效率大於單層標準元件之兩倍，發光功率效率亦大於標準元件。 | zh_TW |
| dc.description.abstract | Organic light-emitting devices (OLEDs) have been developed as a potential display technology. Active matrix organic light-emitting devices (AM-OLEDs) consisting of OLEDs and thin film transistors (TFTs) have been applied in displays due to their superb quality. Since most TFTs are n-type, it is desirable to use inverted OLEDs to connect with n-TFTs to achieve better performances. In order to enhance the lifetime of OLEDs, lower drive currents yet with high luminance are required; therefore, it is desirable to develop tandem OLEDs.
In the first part of the thesis, we investigated inverted OLEDs. For the hole-injection layer, we used novel organic hole-injection materials and investigated their effects on devices. For the electron-injection layer, we used several n-doped electron-transport materials and investigated their effects on devices. Finally, we fabricated green phosphorescent inverted OLEDs with high efficiency and low drive voltage, which are comparable with those of the conventional non-inverted OLEDs. In the second part of the thesis, we investigated tandem OLEDs. We used two different types of charge generation layers – “hole-transport material/ organic hole-injection material/ n-doped electron-transport material” and “hole-transport material/ mixed layer of hole-transport material and organic hole-injection material/ organic hole-injection material/ n-doped electron-transport material” – in tandem OLEDs, and fabricated phosphorescent green tandem OLEDs with high efficiency. At a high luminance, the current efficiency and power efficiency of the tandem OLEDs are twice higher and higher than those of the single-unit benchmark device. | en |
