提出了一种新的用于有源矩阵有机发光二极管（AMOLED）的电压编程像素电路，该电路采用可溶性有机薄膜晶体管（OTFT）。该电路由四个开关TFT、一个驱动TFT和一个存储电容组成，并用HSPICE进行了仿真。所提出的电路可以补偿由OTFT的阈值电压退化引起的OLED电流的不均匀性。仿真结果表明，与传统的2-TFT像素电路相比，3V阈值电压偏移对应的OLED电流变化减少了30%。
A new voltage-programmed pixel circuit using soluble-processed organic thin film transistors (OTFTs) for an active matrix organic light emitting diode (AMOLED) is proposed. The proposed circuit is composed of four switching TFTs, one driving TFT and one storage capacitor, which is simulated by HSPICE. The proposed circuit can compensate for the non-uniformity of OLED current caused by the threshold voltage degradation of the OTFT. The simulation results demonstrate that the variation of OLED current corresponding to a 3V threshold voltage shift is decreased by 30% compared to the conventional 2-TFT pixel circuit.
