提出了一种新型的有源矩阵有机发光二极管显示器像素补偿电路，该电路采用耦合效应掩膜技术对驱动薄膜晶体管的阈值电压进行正负补偿。采用In-Zn-O薄膜晶体管工艺制作了20个分立补偿像素电路。经测量，所提出的像素电路的非均匀性显著降低，平均值为8.6%。此外，有机发光二极管发射电流在6小时连续工作期间保持恒定，这也证实了所提出的像素电路的有效性。
This paper presents a novel compensation pixel circuit for active‐matrix organic light‐emitting diode displays, in which the coupling effect mask technology is developed to compensate the threshold voltage of driving thin‐film transistor whether it is positive or negative. Twenty discrete compensation pixel circuits have been fabricated by In‐Zn‐O thin‐film transistors process. It is measured that the non‐uniformity of the proposed pixel circuit is significantly reduced with an average value of 8.6%. Furthermore, the organic light‐emitting diode emission current remains constant during 6 h continuous operation, which also confirms the validity of the proposed pixel circuit.
