Abstract
Abstract— We have developed an integrated poly‐Si TFT current data driver with a data‐line pre‐charge function for active‐matrix organic light‐emitting diode (AMOLED) displays. The current data driver is capable of outputting highly accurate (±0.8%) current determined by 6‐bit digital input data. A novel current‐programming approach employing a data‐line pre‐charge function helps achieve accurate current programming at low brightness. A 1.9‐in. 120 × 136‐pixel AMOLED display using these circuits was demonstrated.
