Abstract

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.
