P‐226: Late‐News Poster: Compact AMOLED Pixel Circuit Employing Double‐Gate TFT Achieving High Threshold Voltage Compensation Accuracy

Abstract

This paper proposes a compact active‐matrix organic light‐emitting diode pixel circuit using a double‐gate oxide thin‐film transistor (TFT). Due to the multifunctional characteristics of double‐gate TFT, the threshold voltage could be compensated more efficiently. The simulation showed better compensation performance in the proposed circuit than in one with only single‐gate TFT.
