利用刮刀技術均勻塗佈大面積有機材料層

Abstract

本論文以發展大面積溶液製程有機發光二極體之純刮刀製程為目的，研究重點在於純刮刀製程之大面積有機發光二極體的成膜均勻性問題。由於溶液製程有低成本、製程簡單、大尺寸製成、可連續式製程等優點，因此相對於利用熱蒸鍍製程之小分子有機發光二極體(OLED)更具有商業化之價值。 在本研究中，將之前本實驗室自行發展的純刮刀製程，以機械化的方式，取代原本的手動製程，得以更客觀的分析影響成膜厚度及均勻性的參數，減少人為因素所造成的不穩定性，在更大的塗佈範圍下，維持所需的有機薄膜厚度及均勻性，降低製程所需成本，使刮刀製程製作有機發光二極體在商業化具有更大的發展性。

The thesis develop solution-processed large-area organic light-emitting diodes(OLEDs) by blade-only coating method. Large-area uniform films and mutual dissolution between different organic layers are controlled. The advantages of blade-only method are low cost, easily fabricating large-area devices, and compatible with roll-to-roll process for high throughput. Replace the original method by mechanized way can analysis the parameters of film thickness and uniformity more objectively, reducing the instability by human factors, and can maintain the desired organic film thickness and uniformity in a larger range of coating. Reducing the costs of the method, and let the blade-only coating method to fabricate an organic light-emitting diodes have more development of commerce.
