A novel feedback‐type driving method for active matrix organic light diodes (AMOLEDs) is proposed for large‐size poly‐Si panel applications. The driver is composed of voltage and current DACs, current comparator, and feedback control circuits. We have performed the circuit simulations with 30‐inch HDTV panel conditions with both mobility and threshold variations of the driving TFT, and confirmed the pixel‐to‐pixel OLED‐current uniformity have been greatly improved compared to prior AMOLED pixels.
