新一代的平面顯示器---有機電激發光顯示器(OLED；Organic Light Emitting Diode)，憑藉著OLED元件的優越條件；反應速度快、高亮度、高對比，逐漸在平面顯示器的市場上佔有一席之地，其輕薄短小的特色，更是顛覆了LCD顯示器的概念。但OLED材料壽命、元件性能差異問題，成為發展的一大阻礙。再著，OLED面板的不均勻，亦會造成畫面品質變差。因此，為了解決這個問題，需要設計更先進的畫素驅動電路來達到，高功能OLED-面板的目標。
近幾年來，許多補償型畫素驅動電路已被發表。在目前的研究中，分為電壓型和電流型。並依其驅動電路結構特性去解決; 如臨界電壓變異、電子移動率、或是儲存電容充放電時間過長等問題。本論文將針對儲存電容充放電時間過長的問題，設計出增加放電路徑的新型畫素驅動電路；提高畫面更新速度。應用於大尺寸面板上時，可以得到更高之解析度與更好的畫面品質。

New generation of Flat Panel Displays, Organic Light Emitting Diode (OLED) with fast response, high brightness, high contrast plays an important role gradually in the further market of flat penal display (FPD). The characteristics of OLED like as bright light、thin、short、small subverts the concept of LCD displays. But the life time of organic materials become the obstruction on the further development of OLED-FPD. In addition, the non-uniformity of OLED Panel could cause the quality of frames worse. Hence, for solve the problem, A more powerful Pixel driving circuit will be designed for achieving the high performance of OLED based FPD.
Recently, many researches were related to the compensating pixel driving circuits have reported. The catalogs of pixel driving circuits were divided into two types as voltage-driving circuit and current-driving circuit, which were used to solve the problems like the variation of the threshold voltage, the electronic mobility and the long time with storing capacitors charge and discharge. In this study, a novel pixel driving circuit with new discharged paths was design in order to solve the long time of charge and discharge. Theoretical and circuit simulation show this design can enhance the frame rates effectively. At the same time, it also achieves better performance such as higher resolution and quality of frame rate for the large size OLED panels.
