Abstract
We introduce a 5T2C pixel circuit in this paper to compensate TFT Vth variation in active matrix-organic light emitting diode (AMOLED) displays. Simulation results show that the emission current error is decreased to less than 10% with ±1V threshold voltage variation of the driving transistor, which is even less than 5% in middle and high level gray. This pixel circuit was used in the 15 inch IGZO TFT - AMOLED panel display of CSOT, and the lighting results show that the pixel circuit can greatly improve the uniformity of display’s luminescence.
